Default Deuce's MSM built tread

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 with 28rs cold side housing
-Ebay "huge/thick" intercooler
-2.5 inch exhaust with cats , resonator and muffler ( all tig welded stainless steel mandrel bent tubing)
-K1 forged rod (reason for my choice being that they are 40 gram lighter than any other option )
-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 (by someone who does head work for a living)
-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
-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













I'm sure there's some stuff I'm forgetting but whatever that's pretty much it. 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" ahaha.

I know there's some less desirable parts in my setup (like exhaust size , ECU etc...) but keep in my 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. And that's the way I wanna pursue it.

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

Don't tell me external dump are hella loud I know what I'm getting myself into.

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


all in 86a/r

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 .

"Team work makes the dream work" as they say loll


thanks y'all

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.

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.

Thanks for opening my eyes on EWG . I had a misconception 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 .

So then I'll redo my downpipe and the first half of the midpipe in 3in and delete my cats . I think it's a nice compromise for better performance while keeping the car somewhat "quiet".

Parts list for 2019 summer:
-AEM EMS-4
-Injector 650 , 850 , 1000 (what size should I consider since I don't have acces to E85)
-Bigger Garrett turbo
-Upgrade the downpipe and part of mid pipe to 3in while deleting the cats
*ATI super damper (do I rly need one at this point??)
*Maybe a skunk2 trottle body
*Maybe add watermeth if needed

Up to now is there anything else in my parts list that is wrong or missing or that someone wants to clarify !?

Don't be shy

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.

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 Haltech . 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 been self sufficent

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 . I think I'm in need of a bigger trottle body before the intake

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
