Though I'm reminded from my subie days, the MLS gaskets for the up pipe would squeal like a banshee if flange surfaces would warp. Like a Reed whistle. |
Wired in two 6-50r outlets.
https://cimg7.ibsrv.net/gimg/www.mia...2bae806b46.jpg I'm tired as shit for paying so much money on small jobs like replacing a flex pipe or welding a bung. Time to pick up filler rod, tungsten and start practicing. https://cimg9.ibsrv.net/gimg/www.mia...445ec97111.jpg Tomorrow, if the weather holds out, I'll try to check compression on the miata and Datsun, and rip the Datsun head off. Then test some wheel fitment on Kmo25's car |

Weather held - post compression update!
I need to craft a timing chain wedge since those don't exist anymore before we can continue further. Pulled the intake manifold off, and unbolted the exhaust manifold. This head doesn't have the oiling rail like I thought it would. Leakdown numbers were: Cyl 1 - 6% Cyl 2 - 6% Cyl 3 - 4% Cyl 4 - 7% Cyl 5 - 20% Cyl 6 - bubbling out the coolant hose. I'm thinking cylinder 5 and 6 are related, maybe losing compression through the gasket. Hopefully pull this off and learn more. https://cimg0.ibsrv.net/gimg/www.mia...3fd1f092b4.jpg https://cimg4.ibsrv.net/gimg/www.mia...5b19d56a1a.jpg https://cimg2.ibsrv.net/gimg/www.mia...005da87ff4.jpg https://cimg7.ibsrv.net/gimg/www.mia...31675f4c2c.jpg https://cimg3.ibsrv.net/gimg/www.mia...2835e10eff.jpg https://cimg0.ibsrv.net/gimg/www.mia...e3aa0d3f49.jpg |
Tested leakdown past my rings today (no head).

400whp on a 6 speed?
People seem to say that after 330lbft (which i assume is less than you have given hp) 4th goes. Do you just keep swapping them out or do you have a methodology for survival? I have no intention of hitting these numbers currently unless i win the lottery but you seem to be safe in a world of dying boxes. |
Last time it dyno'd successfully, it put down 402whp/375 torque. It had a boost leak. I fixed the boost leak and 18psi/Vladitune had reworked the map, it made enough to slip the "unslippable" FM2 clutch on the dyno. After replacing that, and retuning it, it makes enough HP that wheels spin from the torque in third gear. So I'm not sure what it made before putting it down for maintenance. This was all while I had 38% leakdown on one of the cylinders.
Honestly it's been mostly mechanical empathy. Not clutch dumping and I have no reason to launch from a dig. Everything else has been a failure point, clutches, axles snapping etc. Now that those are fixed and replaced, I'm putting the stress right back onto the gears. It's inevitable and I can feel it in my bones, that a broken trans is just around the corner. I have a BMW 6 speed on standby, but honestly can't bring myself to spend more on this car. If something like a trans failure happens, I'll probably just start parting things out to downgrade and pay for a kswap kit. Or any other reason to start fresh on an NB1 shell. https://cimg7.ibsrv.net/gimg/www.mia...ebfb4054b4.jpg |
Even in my wildest dreams I do not wish to top 348whp which should be under the 330lbft 4th gear death limit so I just wondered.
I'd love to say I'd have the empathy but unable to pull out of a junction, i'm going to forget and launch it like i was at the strip. My plan includes four power level currently. 232bhp - I've been told this is easy to breach and safe on a 1.6 232whp - I've been told this is on the safe limit for a 1.6 348bhp - When the 1.6 goes this will be my first 1.8 goal 348whp - This is my balls out dream but I do not wanted to be changing parts every few weeks so it may be a pipe dream. |
Empathy isn't a full time requirement, but more helps. I've definitely done a couple hard launches for fun, but I'm at a point where carelessness becomes dangerous. Full tilt, will that bump put me in a wall? Am I willing to go to jail for this speed? Honestly, it just takes some common sense and having enough to lose to keep you in check. Keep in mind my build is from the age when EFR's were few, and transmission upgrades were near non-existent. ::shaking cane:: Back in my day there weren't any easy button options like KMiata and Trackspeed kits. What a time to be alive; they've paved a path of reliability for future generations.
People say this and that, a lot of it can be conjecture if they don't have first hand experience. Echo chamber of old "common knowldge." Like why people are still buying Begi/Bell/Max-G products is beyond anyone on this forum. I chose if it ain't broke don't fix it. The trans is the last thing I've had to touch in my car (since first swapping it in) aside from my stock dash and carpet. That being said, this thread is only my experience. You can plan your perfect build all you want, but the best car is the one that runs, not that sits in a garage for years waiting to be completed. You're wasting money having power goals in stages in my opinion. Don't bother with a 1.6L, that preceded the first post of my build thread. The same amount of money you'd be spending on modifying and building up a 1.6L, simply because you already have it, is lost in all comparable power gains if you just invested an extra $400 on a bare block, crank, and head...even if it's a lowly BP05. Build to be overengineered, and don't replace parts. I'd argue build it for 400hp, but run it at 250hp. There's nothing wrong with a factor of safety. When you feel ready for more, add boost, add ethanol, add injector duty cycle....there free upgrade. Spend once. You've been told a lot of things by a lot of people, but the above is told by someone who: - Had a 1.6L - Built a BP4w - Built a BP6D - Had two different Borg Warner EFR Turbo's and three different housings (from t25 not t4 twin scroll) - Has had three built heads - Replaced a clutch two times because it's been overpowered - Had three intercooler setups - Had three radiator setups - Had three suspension setups - Had two brake setups - Had two different set of ID injectors (ID1000/1300) - Had two different fuel pumps - Had three different fuel rails ...and so much more. Set your end goal, stick with it, don't cheap out where it counts or you will pay for it much more down the line. Take your girlfriend/boyfriend/spouse out with what you've saved because they are being real patient with your hobby. There are a ton more people on this forum who've been here a hell of a lot longer than me and have earned their Sage status because they've been through every stage of this tenfold. I'd say read up on what some of those guru's have done and take that over any clubroadster, fb, low post count chatter. Research is your friend here, and you're already off to a good start, just be wise about your build approach. |
:likecat: Set final goals before starting. Some things you can only guess... will I track the car, for instance. But, one should contemplate such things and give it your best shot.
|
I will echo: buy once, cry once. Outside of the parts costs, think of how much labor you are duplicating by going in stages? I don't know you, but I know that for me my free time is very valuable and has multiple competing demands placed upon it. Ultimately, working in the garage took a back seat to work, family, and other obligations so now I'm paying someone else to turn the wrenches and get my project back on the road. Had I got stuck at the equivalent of your Stage 2, Stages 3 and 4 would have been a pipe dream. Instead I'm able to get to my goals nearly within my adjusted budget because I planned ahead and got the stuff I needed to support my goals two years ago.
|
I approve of K swap NB1. Do that.
|
Could even add his fancy 6758 Twin scroll to the K swap for added pucker factor
|
Buy once, cry once.....man, I wish I knew that one before I started all this :rofl:
I wish I started on an NB This is why it's hard for me to put this car back together right now lol. |
Don't worry I'm not planning on buying more than once for almost anything.
Manifold and turbo are the only bought twice, things. |

I do not have the time to jump ship to a 1.8 so will not. When the 1.6 goes the 1.8 will be ready and simply slotted in. Someone will gain a manifold and turbo i cared for greatly for less. |

Sounds like you have all the information you need then! Hopefully you will populate a build thread someday.
It is my birthday tomorrow and I'm fitting parts then so yes the thread will begin very soon :) |
If I'm the statistical anomoly, then definitely err on the side of caution. Take a bunch of pictures! Happy early birthday :party::party::party:

This is the exact reason my powertrain is still bone stock even though the rest of the car is fairly wild. Buying once and crying once on my planned powertrain is turning out to be a gross number on my spreadsheet, but I know its the right way of doing things and will cost me the least in the long run for my end goal. |
I regret nothing about the BMW 6-speed swap, as a data point.
|
^ I can 2nd that, only with the bmw 5speed. I love it!
|
Stop talking about BMW transmissions! I'm in enough hot water with the wife as it is.
|
I'm struggling to find the will power to spend more on this car. - _-
|
The K Miata BMW shifter feels like a bolt action rifle. And the Billet machined aluminum flywheel is really sexy.
|
Some changes in living situation and finances are going to be happening in the next couple months that is going to make it much harder to continue with the car. As everyone already knows, its better to part a car out to recoup costs but I may be posting a feeler soon just to get a sense of what this might be worth to folks. I'm sure I'll get a lot of offers for $3000 because no one wants to inherit this kind of vehicle unless it was self built.
Otherwise I may be proceeding with a partout sooner than anticipated. I'd have loved to get one more season out of it, but I need to make a fiscally responsible decision now more than ever. Edit: Merry Christmas! https://www.miataturbo.net/miata-par...partout-99840/ |
Maybe we should temp-ban you to prevent a partout, lol.

Hello all, time for an update.
It's winter again which mean I'm in crisis mode trying to figure out if I have motivation to continue this project. As many folks already know, I struggle from time to time with parting out and starting over from scratch. I've talked to Shibby about it for over a year, and he finally pulled the gun and decided to move on. Buy His Stuff Here. I made the mistake of tabulating a for sale list and was staggered how much I have in this Miata and saddened about the amount required to cage it and buy a Kmiata trans kit to make it as reliable as can be. I just don't think I can cross that hurdle. Even though I already have the Getrag transmission on standby. Then it's axles...then its..... I've described it recently like being in a bad relationship. You've settled, you're comfortable, don't have the will power to change, but secretly look at other cars/projects and think of what could be. I question if I actually enjoy working on this car, it has no nuance. I love working on my friends' cars and find the quality of work is generally higher than what I commit to working on my own. It comes and goes in waves; the urge to part out because it makes financial sense. But sentimental thoughts reel it back in, and it's a pretty tumultuous cycle. I have to admit, I could use the liquidated assets for other things right now, house stuff, accelerate loan payments, even pick up a shell and start over with a more modest build that would be more huckable around the track. Tax return this year is pretty garbage so that doesn't help....that would have been my ticket for the BMW trans kit. I feel like I've crumbled at the finish line before me. It's just a question of part out now - rip the bandaid off, part out later after enjoying it for one last summer/MATG, or try to sell it whole and take a massive loss but be done cold turkey. As it sits the car is not assembled. Head is coming back from the shop soon. Lot's of changes to the setup that I may or may not actually get to run depending on how things go. This will be the third iteration of the build and there's still a make-or-break test I need to do. Leakdown past the rings. If it sucks, then I honestly wonder if that'll be the tipping point. If everything is fine, then I might just mindlessly continue reassembly and squeeze one more season and a couple track days in before parting ways. If there is any catastrophic failure, I don't think I'll rebuild. If the stock 6 speed shreds after 18psi tickles the megasquirt, then I don't think I'll rebuild. New for 2019: Refreshed head with cams. I suspect leaky valves, so I had it sent off for a checkup. Also sporting the Supermiata reroute. I also happened to stumble on another set of tomei cams and impulsively purchased them which I fully regret. 2019 year of regrets. Fluidampr - just something to try. No reason really, the Supermiata damper had been fine but again, I've been impulsive because boredom. Twin scroll manifold Top mount ramhorn. I'm keeping the EFR6758, but going to try out the 0.8 A/R T4 turbine housing. It's probably a bad idea, but this bad idea has been brewing for nearly two years; I'd even spoken to Abe about it before he committed more time to family. It's just been an ear worm after talking to matrussell122, Geoff at Full-Race, and a couple other folks. Just want to try something different because I'm bored and need stimulation. If it sucks, at least we will have data, and I can always go back to the trusty old single scroll. Ridge Fabrication was able to jig my Artech manifold so it keeps the same downpipe position and compressor housing orientation. It's an easy comparison because downpipe and intercooler are untouched. Very cost effective. Dual port IWG and 4 port EBC. I still envy Aidan's potentiometer controlled boost set points. Aero?! I have a splitter, designed by afm that I've been meaning to mount for some time. I also have a 9 Lives Wing because I'm cheap on the aero. Or I could sell it all and part the car out. I don't know. I already picked up a paint matched trunk for $100 so I can cut it up for the uprights. ABS Knuckles?! still need to replace all the bearings and hubs. I'd also like the transfer the SADFab upper spherical bushings but will likely have to torch the sleeves out of the current knuckles. I want to pirate the ABS sensors for possible traction control. Or just get rid of it. If you made it this far, thanks for listening to my complaints. Just in a pretty bad funk. Your reward https://cimg7.ibsrv.net/gimg/www.mia...b044f09fe9.jpg Getting messy https://cimg8.ibsrv.net/gimg/www.mia...310ab31bc8.jpg TLDR; Financial priorities are changing. I'm not sure if this project does it for me anymore. I kinda want to start from scratch. I don't know if I should reassemble once more, enjoy and part out...or just start gutting it while I'm ahead. If I catch some inspiration to try one last time we can look forward to a cammed VVT head with a twin scroll setup for science. I have too much pride to start a go-fund-me for trans kit, but would gladly take stickers and poscats instead. Hi buddy, interested in those T4TS results !! Did you test it? |
He parted out the car. As far as i know im currently the only one with a TS BP motor and its sold to another member but hasnt picked it up yet. However there should be dyno results by end of summer.

Who is the new owner? Thanks in advance |
Nope never put the motor in the car. Built the motor and shortly after I put an UBER head on the motor i said f*** it and went to a K swap

Anyway I would like to see that test. Keep going man! |
