justin911 Posted March 11, 2006 Share Posted March 11, 2006 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 Link to comment https://www.sau.com.au/forums/topic/109249-hks-gt-rs-rb25det/ Share on other sites More sharing options...
Busky2k Posted March 12, 2006 Share Posted March 12, 2006 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!

Beeble Posted March 12, 2006 Share Posted March 12, 2006 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 Posted March 12, 2006 Author Share Posted March 12, 2006 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. Link to comment https://www.sau.com.au/forums/topic/109249-hks-gt-rs-rb25det/#findComment-2012422 Share on other sites More sharing options...

Beeble Posted March 12, 2006 Share Posted March 12, 2006 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 Posted March 12, 2006 Author Share Posted March 12, 2006 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 Posted March 12, 2006 Share Posted March 12, 2006 ^ 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.

Reedy Posted March 12, 2006 Share Posted March 12, 2006 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 Posted March 12, 2006 Share Posted March 12, 2006 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 Link to comment https://www.sau.com.au/forums/topic/109249-hks-gt-rs-rb25det/#findComment-2013299 Share on other sites More sharing options...

FATGTS-R Posted March 12, 2006 Share Posted March 12, 2006 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 Posted March 13, 2006 Author Share Posted March 13, 2006 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 ?
