Anyone Have A Gt Rs Or Gt Ss Turbo On Their Rb20

[AntonRx7]

Anyone have one on their R32 and what is it like lagwise, wat sorta power etc.

Also which turbo would you recomend the RS or SS

[AntonRx7]

the brand is HKS if that helps

[1400r]

from my understanding a Gt ss is just like a stock replacement turbo ie base model hks turbo the gtr-s would be interesting as its supposed to have the responce of a 2530 but top end is equal or greater to a 2540 so if you can afford one go for it. I'd say you should go for a ride in 32 or ceffy with a 2530 and see if you like the responce of it I know I was shocked how laggy mine felt with a 2530 after hearing how non laggy these turbos are.

[AntonRx7]

yeah i don't know anyone with a 2530. so you recon a gt RS turbo would be better than a 2530? its gona cost me 3k to get a brand new one installed (the GT RS

we have twin 2530's on our GTR.....yet to see a GT RS powered car come even close to our power levels. Dont be fooled by the marketing ploy of HKS...the 2530 is the best small turbo they have ever produced.....Why do you think MINES run them on their curcuit R34.

I can assure you an Rb20 would make a boatload more power with a GTRS turbine than it would with a 2530.

[AntonRx7]

the guys that i may get the gtrs from recon that it would be too laggy on my r32 cause its a rb20 and auto

[Roy]

Huh... you are basing feedback from a twin GTR setup to a single on an RB20....im keen to see what a GT-RS can do on an RB20...but no Rb20 owners have come up with the coin yet so the masses wait patiently

I imagine a GT-SS would be very similar to the 2510, so can make a pretty solid 200rwkws at 1.1-1.2bar

The GT-RS seems to make 250rwkws on RB25s, its yet to be seen if on an RB20 they make the same numbers with the same boost. Im gueesing it can make 240-250rwkws , but may need 1.3bar to do so, and may only make that sort of boost at around 4,500rpm....

The above is just pub talk...so just some guessing looking at what other cars are doing with these turbos

[AntonRx7]

so it may be better to stick with GT SS so i don't ahve to run so much boost as it is a standard engine with front mount exhaust filter fuel pump, i will get injector and tune wafter when i can afford it but engine is gona stay standard for a long while

[1400r]

I'd just buy a Garrett turbo something close to 2530 or 2510 if I was going to go new and sticking with the auto trans should cost you under $2,000 easy no need to spend 3,000 on a gtr-s if you will be happy with 220 ish

[netrati]

I don't know how the SR20 compares to the RB20 as far as power output goes, but I currently have an HKS GT-RS turbo on my SR20 making 250rwkw. Boost is 1.2bar, 260/12mm cams, PowerFC D-Jetro, port and polished head, 1.1mm headgasket for 8.8:1 compression.

[AntonRx7]

i got quote 2700 to suply and fit a 2530 Garret turbo brand new. for the extra money i would rather go for the gtrs due to the workshop is more know that will do it for 3k.

Unless i can find a garret install for more like 2000 no ones seems to want to give me a price and if they do they recon you need lots of custom stuff. like manifold etc which doesn't make sense. (i figure they don't know wat they are on about)

[boostn32]

a mate has a HKS GTRS that has been fully rebuild, and done in japan not here. never been on an engine since rebuild, it basically brand new. hes only after $2400

[AntonRx7]

thanks but i'd rather get the whole kit in and done for 3000. That way i know its brand new and i don't have to get oil lines etc

[netrati]

$2400 is a little steap for that turbo used, rebuilt or not.

[boostn32]

k hows $2150 sound

[1400r]

contact horse power in a box he has them (bolton Garrett turbos for rb20) for around $1890 and fit it your self you big girlie girl he he jk if I can fit a 2530 you can fit a bolt on turbo trust $1100 is a lot of money for something you can do yourself.

[netrati]

HKS GT-RS turbo brand new should be around $1900US. Take 1400r's advice and install it yourself!

[RedDrifter]

Bugger the GTR-s was the one I should have got.

How efficent would one be at 20psi on a RB20 ?

[AntonRx7]

don't oyu need to weld the dump pipe and stuff though. i changed the turbo myself on my wrx so i would be able to manage i just want to make sure i get all the parts i need with no welding
