I pulled a engine from a 92ls400 I tried to filp the exhaust manifold. The oil filler is in the way when I pulled the a/c on the other side the alt I'd in the way. So ? Is what manifold are best. I've seen crown work but none in the us. http://pages.ebay.com/motors/link/?nav=item.view&id=190827359686&alt=web

Didn't know if these or 2uz work better. I'm planning twin turbo setup

 

lextreme's turbo fab forum is where you want to be. iirc you have to relocate the filter and flip the alternator if you're going to run a front-mount turbo on the xUZ motors.

 

thanks for your info. im on lextreme but cant post for some reason. looks like ill have to look in the the alternator thing.
