Aussie ls1 turbo build Gday guys, this is my 88 holden, {gm}, vl commodore.
The running gear took me a bout 3 months to complete, and its my v8 turbo, and i love it.
Modifications are, ls1 engine 346 cube, all stock exept for 1000cc id injectors,fuel rails, 92 mm throttle body, commetic head gaskets, arp head studs, cleaned up bowls to drop comp , duel valve springs, comp cam, moroso oil pump,harmonic balancer, and rod bolts.
It has a precision pt 8847, precision 66mm gate, modified truck manifolds, through a 4 inch exhaust.
It runs a 2 speed b&m glide, 2500 converter, through a 9inch diff. Tyres are 275x60x15.
It makes 700hp on 14psi, using pump e85. And 750 hp atw on 17psi.
I drive it to the track, which is about 60 kms away, and its rub a n 8.97 @151.7mph on screwed radials, full exhaust, filter etc, just strap the chute on.
I drive it at least a couple hundred miles a week, the wife and kids love it.
I was going to take it out again, but i found out my turbo is stuffed.
Ive posted some pics, cheers for the help from this forum, much appreciated.

nice job,
Got any pic's of the turbo side manifold ?
did you have to cut the fire wall to get down pipe to clear ?
I'm building a VK LS turbo, motors in, gotta work on manifolds, haven't been able to find a forward facing factory manifold that will clear cassis rails yet..

Not mine, but someone on LS1Tech did fab this. Obviously they cross over to the other side, but it could route downwards into the turbine and then the DP could pass underneath ?
I've saved loads of photos from turbo setups and various manifolds, i can email them
