This is my buddies 1981 928 with a LT1 conversion

Im not a huge fan of the swaps but he did a really good job. Its about as quick as a chipped and cat deleted 951, so Id say thats quite a bit quicker than the stock 4.5L

KuHL 951

It's just not the same though unless it has 7 oil leaks

That thing sounds down right mean. Nice job!

Nice job on the swap, but it just doesnt sound right... sounds like any camaro at the drag strip...though it does sound mean as hell

I like it but I really wish he would have installed another 4.5L along with his turbo kit that was previously installed.

what 4.5L engine is that?

Wait, back up a bit. He removed a twin turbo 4.5 for an LT1?

Not judging, just looking for clarification.

He removed a single turbo 4.5L as a rod didn't hold up to well under the high boost levels. So he installed a cammed LT1 (I don't see the intellect in it either). I have the kit currently and will fit it to a 928 one day. Its a very simple set up.

How high? My 81 is the same short-block and I've been running 17psi for a few years now. 12psi before that.

Another local supercharged 928 (87) has been pushing 30psi longer than my car has been supercharged.

Rod issues are very rare with 928's.

ooops, duh.....nevermind...

I suppose this one was a odd case. The turbocharger that was used in the application is a little larger than my 61-1 and the boost settings were always 15-25lbs depending how heavy his foot felt. The car was wicked.
