Gtr Tune

[GODZILR32]

Hey guys how much can i gain and what can i achieve just by tuning my "stock" 32 gtr and is it expensive

cheers

[levinboy]

Define stock??

Exhaust cam gears and power fc and a little more boost I saw a gain of 57kw at the wheels 203 to 260awkw and good fuel economy surprisingly

Cost wise:

Cam gears-$200-400

Power fc -$800-1400

Tune-$600-1200+ depending on tuner

Exhaust something over 3inch cost varies

Oh and search next time and look at the rb26 dyno thread

[DVS JEZ]

Full exhaust 3.5inch after cat, cam gears as above then a nistune ($1100 supplied fitted and tuned)

Oh and a boost controller to up the boost to a max of 12psi

Agreed, except boost, 12psi is stock on a GTR, pull out the restrictor and you get 15psi, a good boost controller will help boost come on a bit sooner by not letting the waste gate "creep" open.

I use 15psi everyday driving/track events and 19psi for drags and dyno with no problems on stock turbos

IIts got a 3 inch exhaust and pod filters. I haven't even driven her yet as I bought it while on swing. I'm really just wondering how much can be done.with a tune and maybe restrictor removed if its not already

[levinboy]

Tune can gears and restricter removed you will be able to get 240+awkw on the std turbos, depending on the tuner

I wielded 260awkw with std turbos, exhaust, 14psi, cam gears and power fc tune

Have a look at the RB26 dyno result thread, top of this page, to see different set up results

^ summed up perfectly.

[GODZILR32]

RReccomended cam gears?

[N1GTR]

Tomei, Racepace, JUN, Toda. Ross (Local) is bringing out a set soon too which will be very well priced and made.

[levinboy]

A few for sale in for sale section too last time I checked

[GODZILR32]

JJust bought a set of adjustable cam gears from an Australian company called ozsome motorsports they SEEM to be.very similar to tomei you can pick like 10 colours they only.cost 90 bucks direct from the manufacturer with free postage. I'm going to take them into a garage when I get them to get an opinion if they think its ok ill see how it goes. if anybody wants feedback pm me

Throw away the fasteners that come with them, and go get some quality fasteners (hi-tensile etc) to use with them

Cheers have you heard of or used these before?any comments? The fasteners are they the bolts to the cam or the adjusters?

[Moodles2]

Adjusters, they tend to come with cheap fasteners. If/when they let go the cam gear will be set to the extreme advance or retard position which is guaranteed to smash at least 12 valves into pistons, 24 if unlucky.

[SargeRX8]

Scary stuff. I couldn't trust adjustable can gears...

[sinistaGTR]

Deal I'm going for is tomei cams and cam gears for roughly 1k plus postage to aus..... Decent deal
