Eventually, When My Fgxr6T Turbo Dies.............

[nelsonian101]

Haven't posted in this section before but here goes.....

I've already raked up over 130,000kms on my fgxr6t. Most work/freeway kms but take it to the circuit (Wakefield, Eastern Creek, Marulan) about 4x/year.

My current mods are panel K&N filter, xr8 intake/snorkel. Stepped pwr intercooler/alloy piping. Bosch ev14 52lb injectors, 5" 100cpi cat.

The car currently runs anywhere between 15 and 18psi boost between 285 and 310rwkw. Last 50,000kms have been over 15psi.

Don't take it drag racing but when I take it to the circuit, it gets pushed as hard as I can for 5 laps at a time with careful emphasis on cooldown.

Have used the good stuff 10W 40 Royal Purple engine oil ($99 5litres!) since after run in from 7,500kms. Oil/filter is usually changed every 7,500kms or 8 weeks for me.

Toyed with the idea of an Earls filter but decided to get the stock one replaced at 80,000kms. This may change when the inevitable happens.

My question is turbo choice.

I love the fast spool up/low lag the smaller fg compresser wheel provides, and want to retain this characteristic.

I am after throttle response putting power down carefully on corner exit at the track (why v8's are superior at the track!) and am afraid if I go to the bigger turbo found on the BF, I will lose this gradual power down control.

I'm not after massive dyno numbers but a lower boost 320-330rwkw would be nice, if possible on a low lag turbo.

Any suggestions?

Thanks.

You can get the stock turbo to 320 - 330! Mine got to 327 b4 I changed the turbo to a Gtx 3540 spec.

What boost level to get 330rwkw on the stock turbo?

and how do you find the lag characteristics of the gtx compared to the stock fg turbo with the small compressor wheel?

Thanks.

Have a lot to learn about these new turbos.

Do these bolt straight on to the fgxr6t and does it offer the fast throttle response I am after?

Made 327 on 19 lbs. The Gtx has a bit more lag than the stocker but you must remember its a fair bit bigger and had a .70 front cover. But it can yield close to 500 rwkws with the right set up.

gtx3076r should spool fast and deliver the same power as a 3582r (standard ba/bf fg f6 turbo)

Those X series Garretts are certainly an improvement on the originals!

GT3592 and a little shot of giggle gas down low

Sounds like you just need to upgrade your gear bud.

Better cooler, intake, exhaust and boost should come right down and you'll make your 330 with your small turbo.
