hey guys

i've got a garrett T3/T4 A/R .60 turbo on my rb25

and im just wondering if its laggier than what its meant to be.

STARTS coming on boost at 4500 rpm, to me this seems much laggier than it should be

everything else is more or less stock, apart from 3" exhaust, pod, boost controller etc.

thanks guys

.6 exhaust housing or front cover? why would u put an after market turbo on with a stock ecu, unless ofcourse you want to rebuild your motor in a few months time once u blow it up.

get an after market computer and get it tuned, might help it, but all depends on the size of the exh housing aswell...

.60 front cover, not sure of rear housing

i put it on because it was the turbo that came on the rb25 that i bought.

Honestly get yourself a stock turbo and put it back on. Power difference probably wont be that much different consdering everything else is stock and holding it back. You'll get good response and better midrange, 4500rpm is crap. Then save up for a proper decent turbo.

That's what i would do anyway.

you will need an aftermarket ecu or even just an safc to start unlocking the power and helping to reduce the lag. Then you will find out you might also need a fuel pump, injectors and afm as your stock ones are maxing out

However im guessing the T3/T4 turbo is oldskool and is only plain bearing? (possible only oil cooled) therefore it will be laggy they some somethign newer which is ball bearing

    • Nah, don't bother doing any actual measurements on the car. Just go ask the inter-f**king-net.
    • I currently have 18 x 9 +30 on the front with 18 x 10.5 +38 on the rear. Absolutely regretted it. Ended up putting 15 mm spacers on front and 25 mm spacers on the rear. Not to mention the rears were like a mm from hitting the coilovers. Definitely would go more aggressive then what you were originally planning. Keep in mind my guards are rolled and cars fair low so you might possibly need to roll guards depending how aggressive you go and how low the car is. Im not an expert but the 18 x 8.5 +25 18x9.5 +30 Sounds like it would sit much better.
    • Hey guys, sorry i have been researching for a few months and absolutely cannot wrap my head around this. I am about to order some rims to fit my R34 Gtt with coilovers My original plan was to order Rota grid R in 18x8.5 +30 235 40 R18 Fronts 18x9.5 +35 255 35 r18 rears But then the thought in my head said this isnt aggressive enough. I want the most concave spokes i can get without too much of poke and scrubbing   So my thoughts now is  18x8.5 +25 18x9.5 +30   My question is will this be the most aggressive i could get it without any guard rolling and does the type of rim style affect the offset / size.   Thanks everyone.
    • Lower parts are there. On passenger seat, bright yellow bit is the release mount. On drivers, bright yellow bit is the lower buckle for the other side. My bet is lowers are tucked out of the way as much as possible for visuals.
    • I'm guessing its a 4 point harness, 3 of the 4 belts are visible. I'm guessing the hidden belt is tucked down between the seat and door.
