after a year of searching for the answer to the issues I had in the FG XR6T and a change of workshops, I have finally joined the 400 club.

what was supposed to be a fairly normal test session at Sydney Dragway after a retune and fuel system upgrade, turned out to be a long journey.

the fg nosed over at 330ft and lost all power. after packing up, I started it up and got a death rattle that sounded like an old state transit train. thinking it was finally the end of the 3576 turbo (had a great run over the 3 years, 335rwkw on 98 and 373rwkw on Powerplus E85) boy was I wrong.

11 weeks (a delay in transport, a break in and a hospital trip) I finally picked up my car today.

Justin at Blacktrack Performance in Cardiff, has transformed the FG into an absolute weapon.

The turbo was upgraded to a GT35/82R, we also added a Gibson Chromemoly HD tailshaft, and the cause of the death rattle..... one stuffed flexplate. so we added a Nizpro HD upgraded plate and ARP bolts.

the result. First run on E-flex was a staunch 466.3rwkw.

considering the Fg is also my S/ST drag car (11.00 to 12.99 class) I had the tune reduced to 438rwkw and another flex for a Mrs tune at 396rwkw.

the change is unbelievable, driving back to Sydney (with the occasional squirt) the fuel economy was below 9.2l/100km (best I ever got was a 12.2 and that was stock) yet smash the pedal, and even im trying to climb out of the boot lol.

so mods done are:

wlabro 460l E85 pump and larger cradle

1000d injectors

Gibson HD 900hp tailshaft

Nizpro HD flexplate

Plazmaman HD valve springs

GT35/82R turbo, flapper mod and 12psi actuator

Xforce 4 inch dump, 5 inch cat and 3 1/2 inch catback

Rapid Systems V2 intercooler, piping and battery relocation.

next step is to test the tune and see where abouts in the10's we are.

cheers

That graph looks beautiful

I know hey. all 3 of them are similar (the 466 one is a big ragged but still... :-) )

Well done bud

Can I say awesome power for those mods - sure its a gt3582 and not a gtx3582?!?

Do you know what boost its pushing?

Why the change of tuner ?

lol thanks. nah definitely a gt (wasn't game to push the extra $$ with the finance minister.. in enough trouble already lol)

new hands, new ideas, wanted a change after nearly 7yrs

I know what that's like

My mods list is very similar to yours though manual not auto, so was interested in what boost you running?

It was 39degC with intake temps starting to climb on the day I got it tuned last month so I got CMS to leave it where it was at 15psi on 98

Will be going back early next year for re-tweak on 98 and eflex tune

thinking maybe need to upgrade tailshaft first though..!

true. running 18psi on flex tunes

glad I did the tailshaft mod now with the extra power. well worth it dude.

Damn that's good power for 18psi!

Guessing the tailshaft set you back $1200-1500?

I was looking at what a couple of other guys have done on here... chromoly re-tube of existing by Propeller Shaft services in bankstown

Got a price of $500 iirc

yeah bout $1500 plus fitting. re-tubes are heaps cheaper though.

been sick of doing things twice, so went the full replacement this time lol
