Harrop HTV1320

[W1CKED]

Hey, i iz WICKED. I have a cobalt 2.4. Since Harrop came out with the TVS for the LSJ, i have been wanting to slap one on my 2.4. I asked around with some questions I had and got reffered here. LOL

So what I wanna know is, what is the limit on the stock internals? Ive heard SOOO many different answers. Some people say under 250, but i heard from a real reliable source that other than the pistons and rods, 325 is safe. Thing is, with FWD, im not planning on making any more than 300ish Hp.

So, I guess i wanna know your guys thoughts, and also, where can i find some internals for this motor? The only thing i can seem to find is the JBP Cams and such.

Thanks for helping out


PS. How come i dont have access to change my Sig?!

With only 300 whp as your goal, you won't need internals. There are cars on here making 350+ on the stock internals.

However, I'm not sure our 2.4l is exact same as yours. Ours is the LE5.

[W1CKED]

yes i have the LE5.

Thats awesome news. Do you know an estimate of when pistons/rods are needed?

For me, and I'm a bit neurotic about these things, I'd do it for anything over 350 wheel. Others may tell you different.

I'm not sure what the threshold is.

Welcome to Performance Autowerks!

Try them.

[ELJonesy]

what cams are you finding?

[W1CKED]

just the JBP cams. I heard ****ty things about them. If i planned on getting cammed id prolly just do regrinds.

thanks for the link Mr. Stone
