does neone know if the intense racing shortblock is a good buy or am i better off to build my own motor? ne input is much appreciated.

I'd probably consider a ZZP race engine if you were gonna do anything. From what I hear, the bottom ends of these engines are finicky about how they are rebuilt.

ok. well i was thinkin of building my own engine. i was goin to go with eagle rods,8.0:1 je pistons, and the xpz hot cam.

If you build, build high compression. Low compression is no fun, and no way to make good power.

yup and the car can still move with a decent speed when the belt breaks

well i plan on running a smaller pulley. right now im riunnin a 3.4. I would like to go intercooled and go smaller. If i do that with high compression is it goin to hurt the motor?

with the high compression you will not need to go to a smaller pulley. the S/C can spin slower and be more efficiant

so what would be a good compression ration to run with on a 3.4 pulley non-intercooled?

I intend to get mine up near where the L36 is...which is 9.5:1. I'd like to get it higher than that, but without spending big money, it's just not gonna happen.

bc i know they make the je pistons in 8.0,8.5, and 9.9:1

But, if you do that, you have to rebuild the bottom end. Kind of up to you if you want to do that far in to it or not. I would leave the bottom end alone, most likely. Depends on the miles somewhat.

well i have to rebuild it neways bc it broke two rods and cracked both pistons.

I see. How bad are the cylinder walls?

the cylinder walls suprisingly are in really good shape. the motor only had 70k on it.

With the M90 you want higher compression for an all out build. I'm going to be very close to 10:1 after I throw in an L26 shortblock this winter.
With a turbo you want to go lower compression because they are much more efficient.

ok. i appreciate the info man. hey do you know if neone makes a strong set of rods for these motors or are the L32 rods as good as it gets?

Really, L32 rods are about as good as it gets. I don't think anybody makes anything for these engines. Even what you find on Intense and what not is just factory stuff.

ok cool. yeah i talked to todd allen at intense and he said they are using the L32 rods in both of there 8 second cars. and the grand prix is making 1000hp at the crank.
