Wow amazing about time you got on here even if i did have to do it all for you This car is unreal guys the amount of custom work hes done on it incredible especially for a guy that does it for a hobby not a job his work is as good as if not better than some business' do.

EDIT a goood job by me i posted the thread and made a few errors ignore the double listing of injectors i didnt realise he's changed them since then

Nice looking car. Looks like a great job you've done on all the fabricated parts :thumbsup:

How/why did you end up with L36 heads on a L67 bottom-end?

 

[Pub247]

I'll answer this one motor has been rebuilt for turbo setup hance the use of eco heads as using l67 manifold wasnt going to work with turbo setup. George at proflow built the motor

Seems obvious now you say it

So I gather the pistons/rods/crank etc are all the L67 boost-ready parts then? Sounds like a good setup

Hey mate top looking car, I'm considering getting mine sprayed black. I read the power output, but what kind of torque does it have? Have you ran it at the 1/4?

PS. Pretty sure they are VY GTS rims, not VX.

Yep thats pretty much it theres no difference really between blocks

I wasn't sure when i posted the thread for him what rims they were i knew they were gts of some sort. New setup isnt complete yet but i'm sure when he takes it down the quarter he'll let people know. torque on the new setup should be beyond the 500nm mark

I feel like a prick for answering all his replies

 

[holdenhero]

Haha, nah its cool.

What torque did he have on previous setup?
