what specific T2 manifold do you have?
Do you have a matching T25 downpipe for the manifold?

 

well the guy i got it from lemme swap it out for a t3/t4 off of someones civic that i can either sell it and recoup my money or trade it for a t25 or 28 so a cheap lesson indeed

 

Basicly but it was a guy that lives 10 minutes from me so i swapped it out with a t3/t4 that could be either sold or traded.

 

Its one of the weld your own deals but i had a welder buddy go over it and he seems to think its ok (guy has ballistic armor welding certifications and is pretty thorough with what he does). got a matching dp too so we shall see where this goes

 

its a used weld your own manifold style but ive had my welder go over it and he seems to think its good. guys got a ballistic armor cert so hes not exactly inexperienced. came with a matching dp with no flange

 

thats good. get rid of the T3 turbo and find a cheap T25 from a Nissan s13 silvia (240sx). these are very popular turbos with miatas, perform well and are cheap.

 

Get a T25, above all.
Theres so much more knowlege to base your build off from with a T25. Its a popular turbo in the Miata world, so finding matching hardware is also easy.

if you dont mind the wait for shipping, i hear Kraken is pumping out a bunch of T2/3/4 manifold/downpipe combos

 

I'm so confused.

I vote throw it all out and start over.

 

Yep. this build is full of poo and it hasn't really even started. You need to step back and start over.

first things first- What is your budget?

What computer are you going to use? MS2, 3, 3x,3pro?

Figure out your power goal- this helps determine the best turbo and other bits (injectors etc.)

Figure out what manifold- or provide some pictures and specs of your current one. Just because a certifies welder says it looks good, does not mean that it is. material thickness is the kicker here. you dont want to go through all this only to have the mani crack in a month.

Figure out what turbo you are going to run. dont make a seat of the pants decision here. A 2560 garrett is a great turbo. Pretty easy to find on Nissan Silvia forums. I believe you want one with a 5 bolt downpipe.

lets start with this for now.

 

I dont really have a set budget, originally it was going to be a greg peters kinda build but then i ordered mspnp2 from 949 and so far thats been the most expensive thing. I was looking for somewhere in the neighborhood of 200ish hp, wasnt even really concerned with the numbers tbh just to make the car a bit more fun than it is now. Ive been piecing this together over the course of a month as far as the misc parts go, ordered some denso injectors from the rx8, a universal charge pipe kit (2.5), the manifold and DP, Innovate Lc2 and DB AFR Meter... Still waiting for the MS to come in but most all of everything is here except the turbo

 

What manifold and downpipe do you have?

 

One of those homebrew manifolds that you weld up yourself and the downpipe that came with it bought it off the classifieds in here.

 

Why is this so hard? Nobody knows what you're talking about.

Point us to the manifold and downpipe, to show us what manifold and downpipe you have. If you can't do that, then post pictures.

 

I see the trend now: make terrible choices based on absolutely zero research. By cheap crap. Try to piece it all together after the fact and somehow "make it work".

In which case, carry on

Heres what I bought

 

your injectors are junk too, scrap them. This is the wrath of buying first and learning second.

manifold looks ok, downpipe will need a bit of work obviously.

DUDE, just buy an MK Turbo kit and be done. you absolutely cannot beat his price with your current knowledge.

 

Even Greg Peters isn't doing a "greg peters build" anymore.

 

Can't say i recognize that downpipe flange. GL fam.

 

the lack therof wasnt a concern at the time, still isnt really I had bought a flange to weld to a downpipe anyway

 

I'm aware. Like I was saying though I was gonna copy the broke and boosted build but MS sounded much better than trying to fool the stock ecu to take boost.
