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.

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 :)

    • Hi All, I'm based in Sydney and want to get hold of 4 stock R34 GTT wheel caps as pictured. Cheers
    • Haha im flattered! Although my poor boat is collecting dust in the garage, as it hasn’t been driven in like 6 months. I forgot the to put the trickle charger on too, so the battery is likely toast now.. I have the frenchys kit. It is fantastic. My only gripe was that the hard lines from the firewall needed some tweaking, however, this was mainly due to my specific turbo and dump combo. The weight and size packaging is much nicer too. I think I have some pics on my build thread somewhere.. my justification for the kit was more “why not” I had gone to the trouble to modernise just about every other part of the car..
    • Actually, ethanol has probably never been cheaper, on a tax free basis, than petrol. With fuel excise being what it is, and only being levied on the hydocarbon component, not the ethanol component, and ethanol for non-drinking purposes not being subject to liquor excise - E85 was cheaper, but not because the combustible liquid itself was particularly cheaper.
    • Maybe? If changing the cat to a higher flowing cat, caused the turbo to spool more quickly, and those areas of the map had not been tuned for the boost level it is now seeing, then yes you would need a re-tune. How dangerous it is running without the updated tune would depend on how far out the tune is with the now higher boost levels, how the engine protection has been setup, is the ECU compensating with a wideband sensor, is the boost control closed loop blah blah million other things... But yeah having said that, I wouldn't be surprised if changing out the cat for a high flow, in say a full 3" exhaust, made no noticeable difference at all. 
    • Ah yep. I asked a auto electrician about getting a cheap rebuilt alternator vs a new one. He also said he used to it back in the day but it ended up costing similar to what a new one would and recommended getting a new one,.
