Hks gtss vs S15 turbo

[sideways boy]

So has anyone got experience of both of these turbos?
Im undecided on which one to get.
Is the gtss worth the extra few hundred quid?
How do they compare as regards spool and top end?

ive the s15 one and its great, plenty of power for what i use the car for, very quick spool with power pretty much all the way through the rev band. max power is circa 320 bhp iirc??

If you can go the extra few quid, the gtss is a better turbo

Ya Money wouldnt be an issue Darren. Does it have a better top end than the S15?

well if money aint an issue get a gtrs and a set of 550 injectors and make some real ponies

gtss will flow to about 360hp

u will need a re-map anyway to get the most from a gtss too

do you have an aftermarket ecu?

hav had 3 gt-ss turbos on my car, great turbo. great spool. i was making 355bhp with 555cc's z32, poncams, etc.......... the last one i used was onn a gtr twin turbo setup, smaller exhaust, better spool, bit less power but had more torque

the oil restrictor in the oil feed got blocked in my last one, killed the turbo. then i ran an s15 turbo. nice little turbo. but no comparison to the gtss...

however..... they are a fragile turbo in my opinion(espically the bearings) , if i was buying again id go for the garrett equivlant. or maybe the slightly larger gt2871r. hope this helps.

I ran one for 4 years on a drift car so i dont think they are that fragile

Also they are made by garrett for HKS with a larger exhaust turbine etc compared to a normal t28

one model gt2871r is the same as gtrs. There are a good few gt2871r models with a lot of differences

pretty sure this is the one to go for http://www.turbobygarrett.com/turbob..._472560_15.htm

i put a lot of reasearch into it when i was buying one but have kind of forgot half of it now

Rule of thumb would be smaller exhaust turbine A/R is more responsive, larger A/R more peak power at higher rpm
