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 :no: could only find 1 referance which was in the sticky rb25det turbo upgrade thread :D

thanks :laugh:

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!

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

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??

^ 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. :D

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 :P

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.

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 ?

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

2535 at 14psi....

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!

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
