Default Rough draft...setup...thing

Here's my rough draft of a setup I've come up with. It's a rough draft because there are some blanks where I haven't really decided what I want or will wait to see what kind of deals I get before I decide. I'm not building it for a good 9 or 10 months so I'm going to slowly collect the parts over that period of time so I can try to get the best deals.

Going for ~200-220 whp @ 8-10psi

14B w/ O2 housing
JGS Mani
Custom 2.5" DP w/ flex pipe & O2 bung
WB O2 sensor & AFR guage
<2.5" race pipe or free flowing cat> *is a race pipe really THAT loud?
FM turbo single-outlet exhaust
<insert oil feed & drain line kit here, inexpensive kit or DIY>
Emanage blue
boost guage
SMIC
RX-7 330cc or Supra 305cc injectors
ACT Extreme Clutch & Fidanza Fywheel
<insert MBC here, possibly DIY>
<insert BOV here>
<insert turbo timer here>
<insert fuel pump here, if needed> (I'm told the the stock pump will probably be fine for my goals)

One of the main reasons I went with the 14B is my DSM friend is replacing a lot of the crap in his car so he's selling me a good condition 14B, O2 housing, J-pipe, SMIC and lower I/C piping for $175. I'm planning on getting a MIG welder so I can get some practice in and hopefully be good enough to fab some of my own piping by the time installation time rolls around next summer.

Comments/opinions/suggestions/airborne feces/mumbling welcome

I would go with fluxcore over mig, cheaper and easier. And later on you can convert to mig

My car has a race pipe and an Enthuza Budget Turbo exhaust and the exhaust is a nice sounding loud. With the cat in place, the exhaust is noticably quieter.

My friend has a Spec Miata and his car sounds very loud. So, for N/A you want the cat in place, for a turbo setup, no cat is liveable.

It sounds like you have all the bases covered for a 200rwhp car. I don't really think you need to waste money on a turbo timer.

I'm still kind of new the whole welding thing so thanks for the suggestion, I'll go that route.

Sounds good, looks like I'll go with a race pipe then. I kind of thought it would be quieter with a turbo opposed to N/A, but it's always good to hear it from someone else. And about the turbo timer, if I can score a used Greddy or HKS timer for like $30-50 I wouldn't mind spending the extra bucks.

I applaud you for trying to get more power with less boost, but, unless you have an incredibly efficient setup, you're probably going to be hitting more like 180-200rwhp with 8-10psi from that turbo.

It's still a perfectly legit goal to aim for, though, as there are things us DIYers could learn from a really efficient build.

Yeah, we'll see. If I can get close to 200 I'd be happy... if I'm able to hit like 205 or 210, I'd be in heaven. Aim high, hit somewhere right below... or something like that

I have almost the same plan, except Im using a 16g. I think the spool will suffer though.. so the t25 isnt off the table yet.

Yeah, I went with the 14B because it has similar spool to the T25, but the exhaust fan in the 14B is much bigger and doesn't run out of boost near the top-end like the T25.
