turbo question...don't rip on me to hard

[godspeed]

ok first off, yes i suck at spelling so you don't have to point that out, and two searching for something like turbo or s15 turbo or gt this gets you so much that i just gave up... so here is my question, is the s15 turbo a good choice to go on a s13 sr...i can pick them up here for around $4-500, and i know that it builts right up, yes i know you have to do fuel things, im thinking about going with nismo injectors 550 or 720's but im not sure on that to, how much hp can an s15 turbo make on an s13...is a t3/t4 a better turbo, i know the t3/t4 comes in diffrent specs but just a genaral ?...or does the gt turbos mount up to the ex/manifoild or do you have to get a new one with that turbo, i see them here for about $800...thanks

The S15 turbo should yeild around the low 300's. You will need to upgrade your fuel though...the Nismo 550's will be enough (720's are too much).

A T3/T4 will give you more power and a better top end. You will need a custom exhaust mani for that though. You can select so many different trims on this turbo that you can have a 460 hp top end machine (that would require those 720's) or a mid-high 300's (use the 550's in this scenario), very streetable, power (read, not a lot of lag).

When you say GT turbos, do you mean Garret or HKS. They are different... But so you know, some of them will bolt up, and others will not. Check the flanges...if they are T2 series or T25, they should bolt right up.

Since you haven't said anything about it, be sure to get a FMIC.

If you are not looking for more than ~350rwhp, the S15 should suffice your needs.

edit: I forgot to add that you will be towards the limits of the S15 T28

as for the fmic, will it be ok to get that later, and just not push the psi on the s15 turbo to much, it sucks if i had the cash i could get both now cheap, they always have used s13 stuff here...looks good to, but i am going to fly back when i have cash and go on a shopping spree, by the way if you guys ever want to go to japan check out this site, http://www.iace-usa.com ...fly from L.A. is ussally the cheappest, i have seen prices on there for 330 round trip...thats what i am going to do...i really want to go with the t3/t4 later on, do you think this is a good choice or should i go with an hks or a garret? I have plenty of time to think about that later..thanks guys!

The T3/T4 is a proven good turbo for little money. If you do plan on going with it later, don't buy another turbo now...especially since you won't be able to take advantage of it (no FMIC!). The HKS turbos are soo expensive...if you're pressed for cash, don't even consider them. If you've got the money, then don't hesitate to buy one (make sure you pick the right one!). They are awesome turbos!

Just my $.02

brand new s15 turbos can be bought for only $900. thats a pretty damn good price.

[godspeed]

actually i think im going to get an illeagal job here so i should get the cash to get both the fmic and the s15 turbo...so people can get 350whp with this no bs..can i just get the s15 injectors..they run around $200 bucks here...well if they have them, they come and go.

Ouch! That's a baaad price. You can get a Forced Performance rebuilt full T28 w/ bb for less than that! If you don't know who forced performance is, ask the dsm guys. They make some of the best turbos on the market today and are HIGHLY knowledgable. Check them out, http://www.forcedperformance.net (look under 300zx turbos, the prices are in pairs, but they will seperate them).

The S15 injectors should be fine for this application...but I would get 550's just in case I want to get a larger turbo in the future.

And keep this illegal jazz to yourself.

its just a club job, everyone here that works at a club isn't soposed to be working...

[WDRacing]

Just so I understand you correctly, you have SR20DET already in a S13 and you want to install a S15 model turbine?? I would say not to bother, assuming I'm correct. Get the T3/T4 or a 3037BB from HKS. I prefer the 3037 but I don't like to go cheap.

FMIC should be almost considered essential for any forced induction vehicle. Being in Tokyo, you should be able to snag a used one from a GTR pretty easy.

no, i don't have a s13 yet, engine or car, i will be going back to america in april, so while i'm here i'm trying to get stuff and then when i return i'm going to buy the car and the engine...as for saying you don't like the s15 turbo, well thats cool but it looks like my best and cheapest option, im sure i will want biger and better later but for $400 i think its a good choice to go with...as for the fmic...i can use a used gtr one...is that a good choice?

yeah i looked at the t28 on their page but the compressor outlet is at the wrong angle(~10 degrees) in order to be a stock replacement (~90 degrees). which is what I am interested in.

:nono That can be removed and rotated. The flanges are what's important, and they are t2 (t25).
