Default Gr4v3r's First Turbo Miata

Hey everyone! Over the next few weeks I will be embarking in my first turbo build (don't give me too much credit a shop is doing most the work) so I wanted to have a place to document my progress and ask any questions without flooding the boards with new threads.

Background: About a 2 years ago i bought a 2013 Scion FRS which opened my eyes up to the joys of a lightweight nimble cars. The problem was every mod i wanted to do to the car was breaking the bank. Pretty much everything was going to cost me ~1000 per upgrade and it got me thinking, maybe I don't need a new expensive car to mod, maybe I should give this miata thing a try. So that's what I did. I put my sweet new supercharged FRS for sale and went looking for a cheap little NA miata.

FRS:


After selling the FRS I bought my first miata. It was a modded 96 with a maacco paint job and stripped interior.



I loved the car and used it to get into autox and I was hooked. I attended every autox event this year and thought the car was a blast to drive. The problem was I hated the aesthetics of the car and how aged it was. It was on its second engine and had about 200k on the dinged up body.

That is when I found my current miata. I found this car 10 hours after it was posted on craigslist. It was a bone stock 94 with 50k miles and 1 owner.

Day of purchase:



I spent the next week swapping over the parts I wanted to keep and then put the 96 up for sale. I brought over the wheels, tein flex coilovers, racing beat tubular front sway bar, and nb2 seats I had purchased. I changed all the fluids, bought a nardi wheel, a motiv shift **** and a hard top to top her off. Thats where she sits today.

Current miata:









I have loved racing the miata in the str class but now that the season is over and I have learned a ton I started to miss having power. So that brings us to today. I did a ton of research on turbo miatas and finally bit the bullet on a used kit. Here is a list of parts I got.

FM Manifold/2.5" Downpipe
Trackspeed Engineering 10MM inconel studs with locking hardware installed
FM 2.5" downpipe trans tunnel brace
FM Silicone intercooler piping
FM turbo intake
Turbosmart recirculating valve
Ebay Intercooler (has a dented tube from a something hitting it, but is only cosmetic.)
SR20 T25 rebuilt before installation with new 7psi Garrett wastegate
FM turbo heatshield
ACT Clutch
RX7 Injectors
MSPNP2 by Brain

Which arrived today!!



Well that's my intro. I will use the rest of the thread to ask questions and post updates. I would love some advice from everyone as this is my first build and dont want to repeat mistakes others have made.

Looks good. If I was you, I would get the injectors cleaned and tested and install them along the MS. Make sure the car runs on the MS before you turbo it. You are also going to need a wideband O2 sensor, you can buy one from 949 racing for around $170

The shop I am going to has a used wideband/boost gauge in 1 I will be installing. I am also going to send the injectors out tonight to be safe.

Injectors were sent in to deutsch werks and the car was dropped off at Moto East in PA on Friday. Here's to hoping we can begin operating this week! Sorry I'm not as capable as most of you all, I wish I could do this in my garage :(

Having trouble deciding if I should get a light weight flywheel. I will be replacing the clutch so now would be the time for it but I feel like $350 is best spent elsewhere. Thoughts?

I just found the Build section of the forums under the Media section. Can a mod please move this thread there? Sorry about that.
