So I went ahead and bought a gt35r off a member here. I did this after talking with a few people witch led me to this plan. AEM FIC, z23 maf, 850cc injectors, top mount manifold, greddy intake manifold, and gt35r. With the aem fic I'll be able to run a max boost of 25psi and clamp the maf so I don't get fuel cut. Going to keep the motor stock for this summer and shoot for 400whp on stock motor.

Cmon, a 35r and 850cc's? Go for ID1600's.

18psi

All this and then you go with a piggyback and run a MAF?

Son, I am disappoint

Oh wow, a piggyback. I didn't realize... unsubscribe time.

I am about to a order a FIC for the 2j it will give me much better fuel control and it will give me timing control. It is a great unit for what it is. Good luck with the new build.

It's piggyback and maf until next summer for when I build the motor everyone on the sr20 forums said don't waste the time with full ems until it's needed. They said for 400whp piggyback. I also might look into the EPROM chip that is tunable. I just like the aem more as I have used it in my last miata until I went diypnp. Erin I'm limited by the side feeds for injectors but fiveomotorsports now sells 1000&1200cc injectors.

Sean the fic is going for 300 shipped I'll pm you the link.

Great build! You sure do know how to work fast.
I am also in the middle of an sr20det swap, and its really quite interesting to see somebody elses approach to a common goal.
I wouldn't mind seeing a better pic of that oilpan, looks like you just started from scratch?
Also, do you know what kind of spool to expect out of a gt35r? I'm personally looking at a gt3071r twin scroll, but If the spool difference is negligible, maybe I'll step it up!

Anyways maybe we can bounce ideas off each other or something, and you should check out my build! Lol the link is in my sig

miatamike203

Yes the oil pan I did from scratch it dosnt look to perrty but it works. I like your oil pan a lot but I don't have a tig welder or the funds to pay a machine shop to machine the oil one down.

Not to sure of the spool I'm going to get with the 35r but I can't see it bei g very laggy on a 2.0L. A lot of the eve guys run it and make good numbers and power curve. If I had the money I would do a HTA3076R. That turbo will give you 30r spool with 35r power. I boxed my rear end in and then used c channel for the diff mount. Should also help stiffen the rear subframe.

I am wondering how I'm going to do my speedo I had to take the tail housing off the tranny to fix the shifter forks. I'm wondering if I could swap over the miata stuff to make it all work.

Boost_addict

I will most certaintly be copying your plan of stiffening the subframe as part of the mount if that's cool . As far as the speedo, I think I'll be going with a standard electronic one.. Screw the miata cluster.. Neither the speedo or tach will do us any good.

Anyways, sweet to see your progress.

miatamike203

The Tach should work i dont see why not unless the tach sig from the sr20 ecu is not a normal 4cylinder tach sig. My tach worked with the rotary i had in there i could tell you what wire is the tach wire on the dash if you need the info. I dont care if you copy any thing lol.


I just ordered the ebay copy of the greddy intake manifold and the copy of the Tread Stone cast log style manifold for the SR. Now just to get the MS2 parts ordered and built. Then ill need injectors and fuel rail the good thing is i dont need to change the side feeds to top feeds. www.fiveomotorsport.com sell side feeds that flow up to 1200cc for only 350.00.

Have you already bought your turbo? The 35r?

Have you already bought your turbo? The 35r?

miatamike203

Yes i alread got the turbo on the way from rlogn.

Boost_addict

Cool it will be interesting to see how well it spools

Nice work, will the engine mount unbolt from the body side?

miatamike203

Nope the engine is mounted to the subframe.

cool

how you going about making sure the trans stays aligned with the diff.

miatamike203

The diff just needs a bracket to hold it up. It already has two mounts that will hold it strait. I made the tranny mount so i could adjust left and right so i could get it strait. Now that i have the drive shaft im going to bolt everything in. then measure the gaps on the u joint. Once those gaps are the same i have it strait.

So today i got my new cast iron tread stone copy top mount log style t3 manifold today. I ended up having to drill the holes bigger and grinding the head flange down a bit as it was hitting the water outlet no biggy. Other then that it is a nice peace for 80 shipped. =]

Now just waiting for the turbo to come and the new intake manifold.

Sorry for no pic my fiancees car was broken into and they stole my camera and a few other things so idk when more pics will be coming.
