Sorry for reviving old thread but in search of building a responsive setup too, bought the car with GT2860-5 already which i find laggy but don't want to go to the hassle of replacing the turbo's with say a -7 or -9, recently bought Tomei cam gears hoping to get a tune soon with those and get abit more torque low end, car currently makes 262KW, not searching for power atm, response is my main goal for now, any suggestions?

Mods are:

Arc airbox with Stock AFM

Power FC

GT2860-5

700cc injectors

HKS exhaust

Tomei Cam gears

Thanks

Cam gears and a good tune might net you ~300rpm but that'll be best case scenario really at the end of the day.

Overall the only two 'simple' options to improve the response is capacity or downsizing turbos.

Thanks for the reply, will put up a post soon to see if someone wants to swap -5's for -9 or -7's with cash adjustment depending on condition of my turbo's as i don't know what condition they are in, obviously not expecting brand new -7's or -9's haha.

Should be stock ceramics, then -7 -9 -5 -10 T88

When you had -9s and I had -7s yours was heaps better response wise, I found the -7s to not be that great

Stock ceramics FTW response wise though for sure

Keep in mind that was with stock cams too with -9's.

My tomei type b's I'm running now were a bit of a disappointment down low for off idle to 3000 rpm response.

I was surprised how good the stock cams are!

Got advised there won't be much difference if i swapped out the -5's for -7 or -9, will just waste my money since i already have the -5's in, so adding tomei cam gears, tomei poncams, arp head studs, and valve springs, hopefully after a tune it will sharpen response abit more than it is now :)

    • Does it make a difference in your turbo having a shorter life if you have a cat converter as it causes that back pressure versus less/no back pressure with a decat? (Not sure if this is accurate) Also slightly different question if you went from a oem cat to a decat or vice versa will it require a tune? I heard if you change the dump pipe onwards it requires a tune?
    • No. Have only gotten as far as contemplating the task of having to put in the required fairly heavy wiring and fusing to run it (along with the big alternator), and preferring not to. But otherwise, it would be nice to have a little extra freedom as to exactly where the compressor is located and free up some space around the exhaust side of the engine.
    • Following from this in a related by not closely-related sense... Because I was buying a bunch of other GKTech stuff, I got some rear subframe collars. The history that leads up to this is: 25+ years ago the car arrived into the country with stock subframe bushes. At some point shortly thereafter I added Whiteline pineapple rings, set up neutral, and it improved the rear end behaviour. Well, it is my vague memory that I was happier with it with them in. Less axle tramp on launches, generally better, etc etc. ~2012 it got a new non-HICAS subframe with new stock bushes. No pineapple rings. I reckon that ever since then I've been dissatisfied with the axle tramp. Recently I've been f**king around a lot with all aspects of the suspension. One contemplation has been to relocate the rear lower control arm front mount points (and do the other things needed to make that work) to improve longitudinal rear grip by getting rid of some of the stupid anti-squat that Nissan ladled into the R32. But.... before doing that I thought I'd put some collars in. And.... The collars are good. The rear sounds a little bit different, but there has been no significant increase in NVH coming up into the body. In terms of rear behaviour - expansion joints on long sweeping elevated freeway ramps that would sometimes cause the rear to jiggle around a bit, no longer seem to do so. It appears that jamming chunks of metal into the gaps in the rubber so they can't move much is a really good thing. And the launch behaviour and general forward traction situation seems to be greatly improved too. It's impossible to be really sure, because the tyres are completely shagged - they are freakishly willing to let go right now. But as an A-B test with the same tyres it certainly seems to grip up a lot better. Highly recommended to anyone who still has stock bushes.
    • Bit off topic maybe but has anyone had a crack at one of those aftermarket electric compressors ? Bit of a search came up with one put out by Speedy Air Spares. Looks interesting and looks as if you'd have to run a big arse alternator. Found this out after the fact as my air con compressor packed it in and soon after my alternator ! !
    • Yes. Needs new ports. Usually just achieved by screwing an adapter onto them. Be aware that any AC compressor that hasn't been used in a long time will very likely have dried out seals and will not hold gas. Oh, and obviously you will require a new receiver-dryer also.
