Skyline95 Posted September 1, 2005 Author Share Posted September 1, 2005 How much power are you chasing Jordan? <{POST_SNAPBACK}> Well im using standard rods so as long as it makes 350rwkw i am happy with that, since i have to keep the revs below 6500-7000rpm Link to comment https://www.sau.com.au/forums/topic/86101-rb2630-r34-n1-r32-gtr/#findComment-1558369 Share on other sites More sharing options...
itbmils Posted September 1, 2005 Share Posted September 1, 2005 Hey J I have almost the same setup - but I have used the std RB26 bottom end. I do have dump pipes – HKS style, with the short twin pipes from the turbo down to the engine pipe (+25awkw just from them I think) I do have a 3.5” exhaust front to back I also have the PFC and the Apexi EBC plus the R34 N1s, forged bottom end with std rods (linished and shot peened for good measure) with some minor head work too (competition valve seats are the main upgrade) BUT I have not got 600cc injectors, I still have the std 440cc, and I still run with the std AFMs Now for the good news - I currently get just over 300rwkw and about 292awkw running 18psi (easy) I plan to change the AFMs and injectors within 6 months and expect to get to 350awkw comfortably. My next upgrade ?may? Also include a bigger FMIC – and I hope to get the same power levels at lower boost (dreaming I know) HtH Link to comment https://www.sau.com.au/forums/topic/86101-rb2630-r34-n1-r32-gtr/#findComment-1558404 Share on other sites More sharing options...

dangerous_daveo Posted September 1, 2005 Share Posted September 1, 2005 To give you an idea my mechanic did one of these with the N1 twins a few years back, and they couldnt find a dyno back then that could hold the car down to tune it out to redline. They were using R32 N1s as well. It made 350rwhp at 4000rpm then just spun up on the dyno no matter what they did. And my mechanic said he would NEVER EVER put his foot flat in that car, it was too scary, yet he's fine driving 500+hp RVRs. That said, the engine did have a fair bit more work than yours. Id say you will easy make that power and it will come on like nothing else. Will be one fun as car!

sewid Posted September 1, 2005 Share Posted September 1, 2005 I agree with Fatz, go the HKS GT-RS turbos instead of the N1s. Link to comment https://www.sau.com.au/forums/topic/86101-rb2630-r34-n1-r32-gtr/#findComment-1559520 Share on other sites More sharing options...
manage13 Posted September 2, 2005 Share Posted September 2, 2005 I agree with Fatz, go the HKS GT-RS turbos instead of the N1s. <{POST_SNAPBACK}> Agreed! GT-RS set up on a 3Ltr is pretty good.

pnblight Posted September 2, 2005 Share Posted September 2, 2005 Not that i disagree the gtrs arn't a good turbo, it's just i have not seen any of them product much better top end at all over (GT2560R/HKS 2530) for the reduced low down responce and spool up. It might just be no body has found the right setup or posted a thread on it. I think markgtr34 made around 570rwhp is the best i have heard about, but i know of plenty mid 500rwhp twin 2530/gt2560r/t517z etc so my point is ,is 20rwhp worth loosing bottom end and responce. pete Link to comment https://www.sau.com.au/forums/topic/86101-rb2630-r34-n1-r32-gtr/#findComment-1560536 Share on other sites More sharing options...
Blitz Posted September 2, 2005 Share Posted September 2, 2005 Good point Pete, I too look forward to seeing a properly setup GTR running the GT-RS turbos producing some big horsepower.

discopotato03 Posted September 10, 2005 Share Posted September 10, 2005 2535's would be a little less laggy than GT-RS's , their compressors measure 69mm where RS's are 71.1 so a little less innertia all else being equal .
