Hks Gt-rs - Rb25det

[justin911]

hey kiddies

Anyone slapped a GT-RS in there rb25det ??? I'm mainly just looking for some dyno graphs please and peoples comments who *actualy* have/had the turbo in there car.

Im trying to decide weather to get a gt-rs or a 2535, I know the gtrs is bigger but i wouldnt mind that if its not that much laggier.

Im sure theres 10000 ppl who have got one, and i did try seaching could only find 1 referance which was in the sticky rb25det turbo upgrade thread

thanks

I'd definitely go the GT-RS, why go the 2535 which is only a little bigger than the stocker?? The GT-RS's response on the SR20 is quite good and on the RB25 it'd be a lot better again!

Back when i was looking at power graphs etc... they seemed to range from 230-260rwkw for the most part, with the occasional freak 290 or so. one guy has over 300!

You'll be right on the cusp of needing injectors (i did mine) or a fuel reg and a Z32afm (i also did this).

Much of a muchness between the GTRS and the GCG Hiflow.

very happy with my choice.

good luck!

[justin911]

cool thanks for the info guys im not realy to concerned with the max power it will make though, moreso when it starts to make boost etc etc.

[justin911]

beeble you got a dyno graph or anything exciting for me to see pls ??

[Beeble]

comes on boost around 3000, full boost (15psi in my case) by ~3500, dies off around ~6500.

Lag is about the same as the stock item, obviously slightly more, but you're never caught lagging out of corners etc...

[justin911]

cool thanks again Sounds like it wont be to laggy at all

I know everyone uses a diff dyno and 10000 factors can change your reading but i thought people were making like 240ish kw @ 14psi with the 2535's ? I thought the GTRS would make slightly more power at the same psi??

[Beeble]

^ i pulled 251 on a different dyno (friend of a friend works on commo's a lot in his shop and has one).

And as i said, people are making a reliable 260rwkw on that turbo, different cars, different dyno, different day.

I don't have aftermarket cams, maybe some of those do?

For what it's worth, a friend's ~260rwkw 200SX runs neck and neck with my lowly 230kw. He gets a fatter number on his dyno sheet. I still manage to sleep soundly at night.

[justin911]

ooooo uve sold me

just need to find one now, thanks again

Not to laggy had one for a year and would highly recommend it.

I got 270rwkw with an exhaust cam, power fc and 555cc injectors and usual mods and I got it from greenline.

[180bfj20det]

Now please dont take this the wrong way. I find it hard to beleive a turbo that looks identical to the stock s14 sr20 t28 with simply a 71 compressor wheel could put out in the 250-260rwkw range....its not the 71 compressor I find unbeleivable, but the small 0.64 exhaust housing with 53mm turbine...

I have one in front of me now, and dam it looks so small (the 0.64 housing).

This thread is about dyno sheets and the HKSGTRS, how about some times sheets to go with it..??

BTW, out goes the door for my GT30r and in for the gtrs

[justin911]

cant add anything to your argument..... but i noticed you said you got one infront of you... wana sell her ?

[FATGTS-R]

I'd hazard a guess the two dyno sheets in this thread so far are a lot more closer than the 40rwkw difference it looks at face value.

The 230 sheet was NOT in shootut mode and done in January which is summer so if it was a hot day it would of read higher in shootout mode.

The 270 was in shootout mode but with an inlet temp of 53 so had it not been in shootout it would of read lower.

[justin911]

reedy also has an exhaust cam, whereas beeble didnt........

Just as a direct comparison, on the same Racepace dyno:

2535 at 14psi....

Have you considered the GCG Highflow? I can personally vouch for it Got one in the Stagea

[justin911]

see now uve complicated the issue hehe thanks though.

would i be correct in saying that the gt-rs will give you the highest figure with the right mods ?

like i've seen a few gtrs graphs that are 270-300kw or so... can you get that sorta figure with a 2535 ?

ive never seen a 2535 with that sort of power but u wont want any more than what i have now... they are a great turbo, and you can pick them up cheap! im more than happy to show you how they go!

im getting mine all finished up this week im hoping so ill let you know how i go also.
