Sup y'all ,

I'm a french canadian called Franck

So long story short I bought an 04 MSM bone stock from a baby boomer six years ago.
The initial plan was to wake her up a bit with simple bolt on , which I actually did ..... But as you guys might already know modding a car is a slippery slope , and a steap one I would say.

So here I'm at with a " DIY pieces together FM2ish turbo kit " . I'm gonna write down my parts list to show you exactly where I'm at and after that I'll discuss what my futur plans are for the 19's summer.

Engine / Turbo kit :
-FM cast manifold
-Garrett .64a/r gt2560 journal bearing
-Ebay "thick" intercooler
-2.5 inch exhaust with cats , resonator and muffler
-K1 forged rod
-Supertech 9:5 cr with wiseco rings( 83.5mm bore)
-ACL race bearing
-ARP main stud
-ARP head stud
-BE stage 2+ billet oil pump
-Stock damper that as been rebalance with all the rotating assembly
-Heavily hand ported head
-Stock valve
-Volvo stiffer valve spring
-Gates kevlar timing belt
-Custom built fuel rail
-Custom built catch can
-AEM fuel pressure regulator
-Qmax collant reroute with 94,00 head gasket
-Vtcs delete with port matching runner porting ( also did port the bottle neck shape at the entry of the manifold)
-Blox ball and spring MBC
-Turbosmart Kompack blow off valve
-Resurfaced oem flywheel
-ACT XT 6puck clutch kit


Fuel / Electronics / ECU :
-Begi oem ECU reflash (junk I know)
-AEM FIC piggyback ( to be able to tweak over the reflash)
-Boomslang patch harness
-MAF relocated post turbo
-Begi 450cc fuel injectors
-Aeromotive 340lph fuel pump
-Fuel system converted to return style
-AEM wideband
-AEM boost gauge

Chassis :
-STD R3 coilover
-STD ajustable link kit
-Paco Motorsports adjustable rear upper control arms
-OEM mazda 3.63 ring and pinion
-Rota slipstream 15x8+35 wheel
-Hankook RS4 225/45
-OEM hard top with garage star bracket
-Soft top deleted












So right now I'm pushing 23psi with 94 pump gas on this setup which I hope to believe is making in the "neighbourhood of 300whp" . My goal for next summer is to make 350whp on a mustang dyno . But I need a setup with rooms for improvement ... like 400whp will be needed a couple a months later when i start to feel "dope sick"

I know there's some less desirable parts in my setup (like exhaust size , ECU etc...) but keep in mind I started with some bolts on that slowly escaladed in what you see today . I'd say after the two first summer I rly started to buy overkill parts that I knew would be able to serve me later when the build gets out of hands.

Parts list for 2019 summer:
-AEM EMS-4 or maybe Infinty-6
-Injector 650 , 850 , 1000 (what size should I consider since I don't have acces to E85)
-Bigger Garrett turbo
*ATI super damper (do I rly need one at this point??)
*Maybe upgrade a part of the exhaust to 3in , from the downpipe to the cats while deleting the cats
*Maybe EWG with a dump ( would it be enought if I keep my current exhaust or am I still killing spool?? )
*Maybe watermeth if needed

The turbo choice is my biggest dilema , I have an eye on several different model :
-GEN2 GTX2867r
-GEN1 GTX2971r
-GEN2 GTX3071r

What turbo do you guys think would meet my goals the best , considering this is a street car and that I don't mind too much about lag as long as when the boost kicks in all hell brakes loose!! I'm mostly doing "supra stuff " ... burnouts , turning corner sideways , pulls on the highway , enjoi some twisty from time to time and maybe doing like a couple amateur drag nights .

I've been a long time lurker here and I don't wanna get spoon fed !! I just want opinion and advices form people who are more knowledgeable than me in turboed miata . I know how you guys are around here and I want your honest opinion,

I'm not completly clueless I'm a machiniste and I know a tricks or two about welding too. I did actually build my car all by myself with the help of a childhood friend who happens to work at a speedshop . I've learn everything I know from him .

Welcome to the forum. If you are not concerned with spool and are doing "Supra" highway stuff, I'm using a GTX2867R above 320whp and have destroyed a 6speed. I have just installed the BMW trans and will be turning up the power. A BW EFR will make more power everywhere so do consider it.

Deuce

Thanks man ,

I did consider the EFR at some point but I just can't fit one in my current setup without changing almost everything .

I'm fully aware that my exhaust isn't big enough for what I'm planning to do .So that's why I'm considering to redo my down pipe 3in and a part of the mid pipe while deleting the cats but I'm unsure if the gain are rly worth it .I'm also considering doing an EWG dump . Or maybe do both ?? I'm trying to find a good solution with what I already have , it may not be the right way but I just can't picture myself trashing my whole exhaust .

Is-there anything to gain from this that justifies the hassle ?? I'm open to suggestions !!

How do you like your BMW trans so far ?? Are you using the Getrag diff too ??

I'm fully aware my trans will be on borrowed time once I get to 350whp+ , but the BMW doesn't rly appeal to me cause I don't see any gain "gearing wise" if done with the miata diff. It still gonna run out of gear pretty quick since every gear are pretty much the same or shorter and the overdrive doesn't change neither.


I'll wait till I break my trans before overthinking it , but until now I leaning toward TurboII trans . Every gear is just a bit longer which seems like a better combo with the miata diff.

I'm using the 363 rear gear and the 6-speed BMW trans which is very close in ratios to the six-speed Miata trans.

At around 300 horsepower the three inch free-flowing exhaust would make a big difference in both spool and efficiency according to data I've seen. It will be even more important on the top side of 300.

There's no reason to use an external wastegate as you go up in power. If your wastegate is functioning properly and controlling your Boost to prevent boost creep (which usually occurs at lower boost levels and not higher ones) there is no reason to go external wastegate. And there is definitely no reason to run a wastegate as a dump. There's plenty of volume in a 3-inch pipe to handle what goes through the turbine and what goes through the wastegate. Plus, having driven two open wastegated cars I can tell you it's extraordinarily annoying after about 6 minutes. And it tends to summon law enforcement from blocks away at some inopportune moments.

Deuce

Thanks for opening my eyes on EWG . I had a misconception idea about the fact that the "dump" is a way to evacuate as mush gases as a bigger downpipe while in fact it doesn't cause the same amount of gases still needs to go thru the turbine housing/downpipe to generate the same boost .

andyfloyd

The build looks really good. I have one question,....how are you running 23psi on 450cc injectors?

For the ECU run a Megasquirt. I would say 850cc injectors should suit it well. I would run a Squaretop manifold as well if you can.

Deuce

Thanks man

My tuner could answer this question better than me . But for what I know we are rising the fuel pressure in proportion of boost with the fuel pressure regulator . And if I recall correctly we are at 86% duty cycle on the 450cc .

I did consider the megasquirt at some point because of all the praise I see around here , but the thing is in my area most tuner only wanna deal with either AEM or ECUmaster . As they say you could get the best ECU in the world if no one wanna mess with it than it's useless.

How hard are they to learn on ?? Cause I do like the idea of being able to do it myself

The square tops are pretty expensive in my area , in fact the new skunk2 plenum are waayy cheaper .... like half price loll . And correct me if I'm wrong but I should still be able to hit my 350whp goal with the stock plenum .

Deuce

Sup y'all , I got a small update

I got my hands on a GT2971r aka GT3071r-wg with a destroyed compressor wheel and damage comp housing .

My friend's shop is specialize in rebuilding and upgrading turbocharger , so he's gonna take care of rebuilding the BB cartridge . We also decided to put a billet 11 blades comp wheel and a 9 blades 90trim turbine wheel . For the comp housing I bought a chinese T04B knock off with intergrate anti surge .

The turbine housing is a T2 64a/r so it should bolt right up where the old one is without any modification. I do have to machine the turbine housing to fit the bigger wheel but it's no big deal for me , I'll probably do it myself at my friend's shop since they have the proper tooling for this.

Bottom line I'm gonna end up with a GTX2971r for almost half price , it's all about going fast for the less amount of money !!

Received my wheels last friday , gotta say they're pretty neat

Deuce

Sup y'all , got a little update

The snow as finally all melted down here in Montréal !! So I should get my car out of storage next weekend .

My GTX2971r is done , finally decided to stick to my current downpipe with IWG for this summer since it will be a drop in replacement deal .









Then I scumbagged my tuner into tuning this thing




Went with the fab9 tuning trigger wheel since it can be both mounted on the OEM and ATI damper. I don't plan on buying an ATI this summer .


Got a set of used 950cc injector for cheap at my friends' shop , they been pressure tested by them so it's all good (no picture tho)

And finally I bought 9 K series COP for like 45$ at Kenny U Pull. Better have some spares than not enuff loll




Decided to go with these for various reason:
-Availability in my area
-Price
-Undeniable capability ( seen alot of drag honda doing well over 200hp per cylibder running those )
-Undeniable dependability ( even got spares loll )
-There pretty tall so it's gonna be an easy deal to machine a bracket for my 04 valve cover
-Because they're all in one piece unlike LS coils where you have the igniter and the coil wire separate. (It's better looking IMO)

So that' pretty much it for right now .

The parts list got a bit more modest since last november because meanwhile I had to change my beater , something I hadn't plan on doing this year but hey such is life.

Still think I'll be able to hit my goal of 350whp this summer with what I have .

Don't be shy , I'm a nice person ..... I'm Canadian

In for Dyno

Deuce

Thanks man

I will gladly provides my dyno sheet , especially since from what I know I'm the only one running a GTX2971 trim 90 on a basic bp .

I know they're pretty popular in the 2.0 NC , but doesn't rly compare

Again I'm not doin' anything that hasn't been done before but I still feel I have a solid combo and I can't wait to see the result

Mudflap

now your talking!

Hi guys ,

Yesterday I took the car off storage .

Did an oil change and built a block off plate on the oil pan for the return of the MSM catch can .

I've also finally manage to identify why my straps were shreding themself by the end of last summer ...... well it appears that the outer ring of my oem damper is sitting sideways .

I'll just order an ATI damper tomorow . Didn't rly wanted to buy one but I guess it's time now .

Also this week I'm taking my valve cover off for machining and building the COP bracket . I'll try to snaps a couple a pics of the processe .

I don't care what anyone says, I've always liked those wheels.

90LowNSlo

I don't care that you don't care about what I say. (I like them too, 5 spokes look good in the right shades...)

Deuce

I'm with you guys

Regamaster's are in my top 3 favorite wheel of all time .

Deuce

The K series COP adapter plate is done only need some paint .

Deuce

Sup guys ,

I'm having some issues with the MS3 maybe you guys can help me a bit cause I'm lost right now .

So two weeks ago I installed the MS3 in the car .

Since I have a laptop that has been built after 95 it doesn't have serial port .
So i picked my friends serial to usb cable and downloaded a windows driver to make it work .
I basicly never been able to make my lap top communicate with the ECU with that cable .
Decide I should try to start the car anyway with the base map just to see what's up.
Car fires right up and idle

Since the car started right up decided to move forward with changing the injectors while I ordered a serial to usb adaptor from diyautotune.
Put the 950cc in pretty easely no major issues , no leak , errthing fine.

Which brings us to last week end , haven't received my adaptor from DIY yet .
So I borrowed the old *** laptop from a friend who happens to have a serial port right in it. ( he only use it to tune the MSD box for his top alchool dragster )
The lap top immediatly connects with the ECU , change the injector size to 950cc and rescale them to 31.5 iirc. ( yes I did hit the burn button )
Try to start the car up , engine's doing some bangs in the exhaust but just won't start .

After a while the engine gets flooded , get the plugs out and dry the whole thing up.
Then try starting it again but the engine just sits there cranking not doing any effort , no bangs in the exhaust litterally nothing but cranking.
Obviously after a while it gets flooded again ,get the plugs out and dry the whole thing up again

THE UNTHINKABLE HAPPEN MY FRIENDS LAP TOP CRASH LIKE NO TOMOROW BLUE SCREEN THE WHOLE THING !!

So my friends computer is still complitly down and I still haven't received my adaptor yet.
So till I receive it I can't do **** but ask you guys what did i miss ?

I've check the 4 coil pack and they are all making fire , i got obviously fuel and air....

What am I missing ?

Anybody as an idea of what's going on ?

Thanks

Injector dead times

x_25

Yeah, check that. I accidently had mine set to 500% correction cruve and had 10ms of fuel at idle on 640cc injectors. Had the same results.
