has any one ever used or seen anyone use a Forced Performance Green turbo on a sr motor. I am able to pick one of them up for around $300(list price is 1300). what are you thoughts on using a dsm turbo on a sr? how many mods would I have to make? also just in general is FP a good company?
here is a link to the turbo and specs.http://linux.forcedperformance...Turbo
thankyou your your time and info

Forced Performance turbo
If you research that turbo a little you will see how far it has taken DSM's. It has been the BEST--still is-- bolt on 50trim for DSM's period. Has put all too many in 11's on pump gas. That is one bad turbo man, i have been in DSM's for too long (I am sure some can relate :p) and finally came over here.
It would do very well on an SR; howeer depending on your power goals it may not be what you want. You will definetly need a custom manifold and/or turbine flange for it, a custom o2 housing--or you could use a DSM o2 huosing and o2 sensor and use a custom flange for the downpipe- and DP flange to bolt to it, water/oil lines will need to be custom as well (which isn't to hard at all actually) as well as either getting creative with some silicone hoses or having a 90* elbow welded on to the compressor housing.
Buuuuuut if you have high expectations then if its in GOOD shape it may be worth it. Otehr wise you will probably save time/money going with something like an Big T28. Good luck!

actually the Garrett GT25 R is capable of 450 hp if you get the .86 AR version and the .64 AR is capable of 400.

I dont have numbers yet cause i still need to get some more stuff before i hit the dyno . It is a t25 with new internals , and it comes back looking brand new! bolts right in , no real problems . The only numbers i know are MAF % at certain RPM. so maybe you could contrast that to your T25 , but i hit almost 100% airflow well before the redline.

I think with a custom tubular manifold, greddy intake manifold, and pretty aggressive cams, with an aggressive tune, you MIGHT be able to get a little over 400. Secret Services has tuned many of the .86 A/R turbos to around 400 hp and these guys are the shiznit when it comes to tuning.
Check out the current issue of Modified magazine. They tuned Enjuku's car to 544rwhp on a stock block.

Just because you own one, doesn't mean it can't get to 450. What is your setup by the way.
Also, for the Big28, does it matter if you get the DSM Big28 or the silvia one? I accidently ordered the bIG28 and already emailed the guy to cancel it, but they seem to not replying their email very well and i'm oversea, always missed the time to call them.

It does matter which one you get.

friend of mine locally made 396@20psi on .86 GT25R so far on 93 octane, stock exhaust manifold, stock intake manifold.

supporting mods are (at least what i can remember):
Greddy VSPLGreddy DP/Apexi N1/greddy turbo outletJWT ECUJWT Cams (can't remember specs on them)50lb top feed injectors/JWT rail/Nismo FPRsome fuel tuning electronics similar to old school AFC's (dont remember brand)Cobra MAF/pop charger
runs were done on BP/Amoco 93 octane gas. stock exhaust manifold, stock intake manifold/throttlebody. ~20psi on the highest run. runs were on a dynojet dyno, done at Balanced Performance in Sugar Hill, GA. Tuned by Ed Senf. i may have left out a few small things but that's the basics of it all. he also has water/alky injection which he has yet to run. the 396hp run was made while the clutch was slipping horridly, and his dyno chart shows the sudden drop in torque/hp when it happens. i believe he's got a new clutch on the way though:D

there are 2 different GT25R compressor trims, one flows 44lbs/min and one flows 39lbs/min, which may be making the difference everyone is talking about with the .86 only making 389hp
soooooooooo how about that Big28.. let's talk about that.
Could I run a big28 on stock injectors at low boost till I get some larger ones? How much whp do you think a big28 can push? I know it's not bb, but I don't really care that much about quick spool, I more just care about holding power till redline and cfm.

wheel... probably won't be much different on stock boost. What the Fp28 allows you to do is run more than 1 BAR of boost without the efficiency problems. It will probably be a few more horsepower at stock boost but not a lot.
