A beginners DIY journey to ITB/Turbo
20 Attachment(s)
Im Will,
A long time lurker, second post ever. My first post was on a hunt for finding something that doesn't exist, and for good reason (Psht, see noobness here: https://www.miataturbo.net/diy-turbo...-flange-86517/). I had no idea what I was doing, and definitely needed to do the almighty research. I have never had much of a plan or direction for the car, I just wanted to make it fun to drive and do all of it in my garage. 1994 1.8l, previously owned and driven into the ground by a clutch kicking couple. I bought it late 2014 so I didn't drive it much. Winter of 14/15 it got suspension components and the ITB's. As well as all of the cosmetic stuff. Summer of 15 I took it to a ton of auto crosses and one hometown drift event for fun. This winter was a big push to make some power since it already has control. So Ill start at the beginning, and dump a ton of pics because that's my favorite part about forums... If you have any questions feel free to ask. There are video links scattered throughout. Ive compiled them here. Miata first start: http://vid1219.photobucket.com/album...331_205937.mp4 Miata first drive: http://vid1219.photobucket.com/album...401_180746.mp4 Miata lunch break: http://vid1219.photobucket.com/album...40174561_n.mp4 Manifold time lapse: http://vid1219.photobucket.com/album...02058928_n.mp4 340whp Civic: http://vid1219.photobucket.com/album...s/GOPR3008.mp4 340whp build thread: http://www.d-series.org/forums/showc...ld-thread.html The day I bought it. August 4, 2014. (Note my 340whp 1.6l civic(I sold it to fund more Miata fun though)) https://www.miataturbo.net/attachmen...ine=1460707079 Order of business numero uno... Control 15x9 Advanti Storm S1's, 225 R-S3's FM Vmaxx Extreme Sport pack w/ sways Full poly bushings https://www.miataturbo.net/attachmen...ine=1460707079 Then some safety with a HDHCHTDD. https://www.miataturbo.net/attachmen...ine=1460707079 I also always liked the look of the 1.6 dash, so when a friend of mine decided to junk her NA (also previously owned by the clutch kickers) I tossed in a few bucks for a ton of spare parts. https://www.miataturbo.net/attachmen...ine=1460707079 Thought number one for power... Supercharged ITB Miata. But I decided not to mess with a ton of throttles bodies and syncing them. https://www.miataturbo.net/attachmen...ine=1460707079 Then this came... 6758. But Im not going to use it. After doing all that research I decided to take some advice and shoot for a low hp setup. https://www.miataturbo.net/attachmen...ine=1460707079 Had to control it, so ordered this jazz. https://www.miataturbo.net/attachmen...ine=1460707079 And put it together. https://www.miataturbo.net/attachmen...ine=1460707079 https://www.miataturbo.net/attachmen...ine=1460707079 https://www.miataturbo.net/attachmen...ine=1460707079 https://www.miataturbo.net/attachmen...ine=1460707079 |

I have to say, for a diy it worked... But Id be pissed if I had to install this as an installer. There weren’t enough relief cuts for hardware on the flange and the vacuum line nipples are directly in the way of the lower studs. But whatever, it worked. https://www.miataturbo.net/attachmen...ine=1460707134 The ITB's I scored were AE111's. The flange was made for AE101's. So I went to Harbor Freight and borrowed a compressor for a bit. Top pic courtesy of T3. https://www.miataturbo.net/attachmen...ine=1460707134 On, the sound neat. https://www.miataturbo.net/attachmen...ine=1460707134 Car didn’t come with AC. I did a proper depowerd rack PS delete, and if it wasnt obvious by the dash pic I got rid of all the HVAC. https://www.miataturbo.net/attachmen...ine=1460707134 And one of my first rollers with it setup to FM recommendations for ride height and alignment.

First day autocrossing it in Helena Montana.
https://www.miataturbo.net/attachmen...ine=1460707170 The previous clutch kicking owner taking a ride in it for the first time after a year of it being in my possession. https://www.miataturbo.net/attachmen...ine=1460707170 The front fenders are full of bondo, and every panel has a different color white on it. So I cut em up for style points. Ive got a fresh set of fenders on the shelf, but paint and body is way down on the list. https://www.miataturbo.net/attachmen...ine=1460707170 Another AE111 pic when the motor was out. Details on why it was out further down... https://www.miataturbo.net/attachmen...ine=1460707170 One of them there lighter flywheels. This has been my first car with a lightened flywheel. Its definitely a different driving style, but the rev matching for downshifts is much smoother and doesnt seem to unsettle the suspension as much. https://www.miataturbo.net/attachmen...ine=1460707170 Most of these pics are in no particular order. Im literally just going through my photobucket frame by frame and posting em up. Mmmm, that EFR https://www.miataturbo.net/attachmen...ine=1460707170 Then I started amassing large quantities of things. https://www.miataturbo.net/attachmen...ine=1460707170 Time for some words from the fabricator. So I basically dove into this head first. I saw lots of different ways to buy the skinned cat, but I like skinning those little shits myself. Last year I tig welded for the first time at work. I work for the local police department. I am the fleet manager for a ~70 vehicle fleet. The kicker is that I also do all the maintenance as well and fabrication needed. Ill post up a few of those fabrication pics before I go on with my own project. They were my practice after all. Project number one with the tig was a computer base. https://www.miataturbo.net/attachmen...ine=1460707170 https://www.miataturbo.net/attachmen...ine=1460707170 Next I mass produced some mounts for the cameras that face into the rear cage of the patrol vehicles. https://www.miataturbo.net/attachmen...ine=1460707170 ###### |

I dont have any good pics of this aluminum ramp I made for the new animal control truck I outfitted. But here was a weld from one of the center supports.
https://www.miataturbo.net/attachmen...ine=1460707245 https://www.miataturbo.net/attachmen...ine=1460707245 Then I made this rad slide out shelf for the generator on the CSI truck. The only thing I didn’t make were the actual ball bearing slides. This was all mig welded though... But the fabrication part was a god learning experience. https://www.miataturbo.net/attachmen...ine=1460707245 https://www.miataturbo.net/attachmen...ine=1460707245 https://www.miataturbo.net/attachmen...ine=1460707245 https://www.miataturbo.net/attachmen...ine=1460707245 https://www.miataturbo.net/attachmen...ine=1460707245 That was basically it for work projects that required welding. Then I got a couple projects that required me to try my hand with the mill. That was a lot of fun. The projects were easy, Im satisfied with the turnout. This is a bracket that holds a particular box in a particular spot, but the original plastic bracket didn’t hold up to the weather while placed atop a telephone pole. https://www.miataturbo.net/attachmen...ine=1460707245 https://www.miataturbo.net/attachmen...ine=1460707245 https://www.miataturbo.net/attachmen...ine=1460707245 ###### |

Next up was a similar box that required a tinted lexan window to be inlayed in the box as well as similar brackets made. The fitment turned out better than I expected. But then again as long as the work piece is square it should be easy. I had to use the 1” bit because the corners are a 1/2” radius and I didn’t have that large of an end mill.
https://www.miataturbo.net/attachmen...ine=1460707268 https://www.miataturbo.net/attachmen...ine=1460707268 https://www.miataturbo.net/attachmen...ine=1460707268 https://www.miataturbo.net/attachmen...ine=1460707268 So yeah, I have a light background of fabrication. I like to dabble... Alright, back on track with the Miata stuff! My DIY ABS door cards with red/black pull handles. They are actually bolted to the doors, not the cards. https://www.miataturbo.net/attachmen...ine=1460707268 One of the past owners was a speaker guy. So there were huge holes in the package shelf. I tried getting a used one, but then a buddy gave me an idea to use license plates to cover the holes. Its my special spot for stickers now. (This car is in Montana, the plates are from when I was stationed in Colorado and Texas). https://www.miataturbo.net/attachmen...ine=1460707268 Here comes a pic dump!!! My manifold building process Refresher pic of parts used. https://www.miataturbo.net/attachmen...ine=1460707268 SR20 T25 is being used. The EFR is just too big for the current stock block. https://www.miataturbo.net/attachmen...ine=1460707268 https://www.miataturbo.net/attachmen...ine=1460707268 https://www.miataturbo.net/attachmen...ine=1460707268 ###### |

I actually bought a tig welder for this project. It was a used Thermal Arc TA185TSW. I outfitted it with a CKWorldwide Gass Lens Kit.
Second bottle and regulator for purge. https://www.miataturbo.net/attachmen...ine=1460707295 Starting out. https://www.miataturbo.net/attachmen...ine=1460707295 This was dumb, I ended up not using a jig like this. Instead I used a bit more math. https://www.miataturbo.net/attachmen...ine=1460707295 https://www.miataturbo.net/attachmen...ine=1460707295 Took it apart, started with the math.

Here is where it gets disappointing. Summer was quickly approaching and I still had to make an ITB plenum if I wanted this to work. I felt crunched for time, I had already done so much this winter and I was really ready to drive this thing again. So I bailed on the ITB's for this summer.
I did make a couple drawings to scale so that I can work on it this summer without the car being down. Unfortunately it is unethical for me to use things like the mill and lathe at work for personal use. So I have to farm out machine work for some of the plenum. But whateves, it’ll happen next winter. Super accurate drawing #1!! https://www.miataturbo.net/attachmen...ine=1460707477 and #2 on Google Sketchup free. https://www.miataturbo.net/attachmen...ine=1460707477 Once I swallowed my pride it was hammer time to get it running. https://www.miataturbo.net/attachmen...ine=1460707477 https://www.miataturbo.net/attachmen...ine=1460707477 https://www.miataturbo.net/attachmen...ine=1460707477 https://www.miataturbo.net/attachmen...ine=1460707477 https://www.miataturbo.net/attachmen...ine=1460707477 https://www.miataturbo.net/attachmen...ine=1460707477 ####### |

Fine work sir, I'm impressed. Love seeing a nice DIY turbo setup, and this delivers.
I like your progress on the DIY itb/plenum setup. If I ever went to ITBs with a turbo, I would take the same approach you are. |
Other than the no BOV your setup is awesome.
|
Many props awarded. Love the DIY stuff.

I like your progress on the DIY itb/plenum setup. If I ever went to ITBs with a turbo, I would take the same approach you are. I really wanted to make a dual plenum design, but I couldn't find a manufacturer that would sell me just a hammer formed cone. And I don't know the first thing about making a die or hammer forming aluminum. But who knows, maybe in the next 6 months I'll source it and change the design up a bit. One of the biggest benefits I saw with the dual plenum design is use of available space. Things get tight at the strut tower. So tight that I'll probably end up having to remove the two triangular braces to make room. Which reminds me, I still need to do a bunch of chassis strengthening.... |

To preface this next part I'll say a few words. When I first went on to build my civic I got heckled a little. But I didn't care. My boss, friend and mentor at the time, gave me his copy of Maximum Boost. Now sure, that book is a little outdated. But the information is still valuable. So with the information as my tools I dove into that one. But I bought all my parts for that build or had someone else make them. That thing managed 340whp in a 1.6l and had room to go still. I had a bov on that, but at 16 psi I could still hear surge. Probably could have used a larger bov. Back to that BEGi kit. A member asked a question about why the kit didn't come with a bov. This was the response he received. "The sole purpose of a BOV (bypass valve, anti-surge valve, other......) is to surpress a funny noise when lifting off the throttle. The noise is proportional to the boost. Low boost systems have nothing to gain from a a BOV. If your intentions are to escalate the power, add in the BOV on the initial purchase, or select it somewhere along the the way. Corky Not enthused about using popular parts that I don't need." Being my plans no longer called for a ton of boost I said screw it, no bov for me. The flutter as a result of surge doesn't sound harsh at all. I like to compare it to a locals MR2 that is pushing over two times the estimated power with no bov. His sounds violent, he really gets that high pitched choo choo noise. So, what's it going to hurt? My $50 T25 Garrett? Maybe my factory 190k motor? Whatever the risk, which I don't see it being much, I've accepted the potential for failure. Much like my manifold. If I was being safe I would have made it out of mild steel, then I could have been a little more careless with building it since the thermal expansion would be less and result in it being less prone to stress cracks. But instead I went stainless, I took the risk that my welds(and material choice), that aren't flawless, will lead to the manifold falling prematurely. I hope none of this sounds like I'm being a dick, it's just how I came to the conclusion of not running a bov. |
We're not heckling, just telling you that running without a BOV is a good way to blow the seals on your turbo. Or do other damage.

I don't feel heckled. For the most part the info and threads I've crossed through on this forum has been very helpful. Stubborn in the other hand, I am. :) |

Still have a long way to go. I need to make a bunch of stuff for temperature control. Previous owners left no under tray or even fender liners it. The issue is easily seen at highway speeds. It runs warmer at 80mph (yay Montana highways!) than it does sitting and idling non stop. A front splitter and boxing off the rad/intercooler should help immensely. |
indeed, get proper ducting in there and you should be good to go.

move your AIT bung to the intercooler outlet endtank...
use that, now empty, pre-tb hole for your boost source. |

use that, now empty, pre-tb hole for your boost source. This is how I see it. IAT temps will be negligible between the end tank and 1' of charge piping. The boost source for the IWG is already right there next to the IAT sensor. I suppose my logic for putting it there was so that the IWG was seeing actual pressure at the TB rather than at the compressor outlet. I also put the IAT sensor in that location because its sorta where it ended up. When it was equipped with ITB's I extended the harness to sit right above the passenger strut tower. So it kinda just worked out that way. |
Because the IAT sensor will heat soak in the engine bay and make for false temp readings.
Cant tell if your boost source is post throttle body, but that is a bad place for it to be. Part throttle will cause overspinning the turbo. And with no BOV even more turbo go boom. |

I'm not doubting that I have nothing to lose by moving the sensor. But this is no hot weather application. Up here in the mountains it doesn't get real warm. The folks down south may have different experiences... That being said, I believe that in my application it is in a perfectly fine and easily accessible location. If something changes or it becomes inefficient, Ill change the design. Boost source for the IWG is pre throttle body. Literally right next to the IAT sensor. |
Boost source is fine then.
It actually is worse in cold weather. The engine bay heatsoaks and it can cause issues. You don't have to listen to any of it, but this is all from a lot of peoples experience. I think I even took a video recently of heating up the outside of the sensor and seeing my AIT go up and the Megasquirt added fuel even though my actual intake air temp was cooler. Car went rich and started stumbling. Video is somewhere around. |

Warm air is less dense, requires less fuel sorta thing. I know under boost more fuel can be used to cool the engine, but I'm assuming you did this test at idle. |

So while I was in there I pulled the intercooler and moved the iat sensor to the end tank. So far I haven't done any logs in the new position. But I can only assume what soak there was should now be gone. I also picked up an EBC that I'll hopefully sick in sooner or later. |
Just seeing this thread now, looks great. Lots of DIY still which is awesome. How much solder/electronics experience did you have going into the Megasquirt build? Did you use a particular build guide?

Hey, D-series buddy! Glad to see youre now on the other best car forum on the web.

Go to radio shack. Buy one of their smaller DIY Arduino kits ($20) and a cheap low amp soldering iron. And just follow the directions and see if you can set it up. If you can follow the directions and make it work, you've probably got what it takes. I literally chipped my first ecu and built my MS using a $15 pen style 20 watt radio shack soldering iron and some solder braid I got at a pawn shop. Link to the Arduino kit. https://www.radioshack.com/products/...ant=7188616645 Here are just a few of the links I used. Some stuff is outdated. https://www.diyautotune.com/support/...n/diypnp-v1-5/ https://www.miataturbo.net/useful-sa...asquirt-13676/ Engine Management Megasquirt DIYPNP "How-To" - Step-By-Step Instructions - Miata Forumz - Mazda Miata Chat Forums Basically everything you need you can find. Some of it takes some searching, but trust me the info is all out there to be had. The trick is using the right search words. Which you will figure out as you go. Start with the diyautotune link. From there that first link can be broken down into almost all of what you will need. My issue was that I learn things differently probably than most. It can sometimes be difficult for me to conceptualize certain things. Which is why I was constantly looking for other writeups that explain the same thing, but in a way I understood. I would say I have an undiagnosed learning disability. But don't tell anyone... You just have to believe that you can do it. But if your only reason for doing the DIY is because its cheaper I think you're gonna have some difficulties. I went the DIY route (with the ecu and everything else) to prove to myself and the nay sayers that I could do anything I set my mind to. I still cant pick up chicks though...

I believe every forum has something to offer though. Even though some of those forums are only good for a laugh... But where would I be without DSO. Also, I made a splitter. https://www.miataturbo.net/attachmen...ine=1463026747 https://www.miataturbo.net/attachmen...ine=1463026747 https://www.miataturbo.net/attachmen...ine=1463026747 https://www.miataturbo.net/attachmen...ine=1463026747 https://www.miataturbo.net/attachmen...ine=1463026747 |

That TIG finger, you watch Jody on Welding Tips and Tricks?

You need a welding jacket unless you want lots of sun burn on your arms. I have been there, done that.

His channel is where I learned 90% of what I know.

So, for the first time ever racing with my local autox I finally won a pint glass. I was racing in XP, which the car is way underclassed for. But with the gutted interior and everything else I kinda get stuck in the catch all class. Not a big deal, and it will never be competitive. But my whole deal with the Miata is just to challenge myself on a mechanical level and have fun all the while. I would say I succeeded that goal and then some. And there is still a ton of stuff left that I want to mess with.
But anyway, heres the pint glass for taking first in Prepared today(this is the first time Ive ever received any sort of "trophy" in autox). Attachment 183726 Said scratched GoPro lens. Attachment 183727 And a lap from today. This wasn't one of my faster laps, seems I failed to record any of the decent laps. And don't mind the hood prop banging around in the trunk. It appears as though I accidentally left it in there after lunch. YouTube Video: |

Oh how our plans change...
First, its notable to mention that the thread title should no longer include "ITB". I sold my setup to someone else. What happened was I experienced some detonation and cracked the top of a piston off. Long story short, I decided to rebuild it using an eBay rebuild kit with the intentions of saving up to go V8. Well again, plans change. I experienced some more detonation causing the same outcome. I tried listing a few things for sale. Like a full LSD swap, trans, motor for rebuild, for sale. Had no real interest in the matter. So I let the car sit for about 6 months. Now, Ive started amassing parts to build my 1.8. I have... Supertech 83.5 8.6:1 pistons, Wiseco XX rings, except through some ordering mistakes I was freely upgraded to 8.5:1 Wiseco's ACL Race main/rod bearings ARP main/head studs eBay H-beam rods w/ 3/8 ARP2000 bolts Gates water pump/ racing timing belt kit BE oil pump gears Balanced internals/rotating assy balanced fly/clutch assy Ive also got a trade in the works for a BP4W head. All I have to do is finish a couple extra sets of these fender braces Ive been making for my car. The trade kinda fell in my lap after posting a pic on a Facebook page. I cant afford to build the head this year, yet... so the plan is to run it but build it next winter. Beings Im a diy type Im building my own rod balancing jig. So I will balance the piston/rod assy and weight match the bearings/rings. But Ill have my machinist do the crank/fly/clutch. Ill check the rods/pistons on his equipment to be sure its all good though. Been working my ass off doing OT to support this winters build. Det monitoring will be a huge priority this go round... but Ill still tune it myself. Ill just have a lot more to lose this time, which is incentive to spend more time tuning it. Ive already got an electronic style det can setup built and plan to buy a knocklite style setup as well. Here are some pictures for your viewing pleasure...

Damn, these are almost perfectly balanced (within .5g) out of the box!

Finished my jig and balanced the rods tonight. Practiced on a few stock rods before getting to the new ones. Seemed to work well, but I will still be testing them against my machinists rod balancer next time I go out there.

Nice DIY setup; expect it to be fairly accurate!
