Modded 86 Slower than V6

Coupe50h · 01-13-2007, 12:48 AM

Did the 86 have the lame flatop pistons dark5.0? I cant remember, but with the heads shaved and an e-cam the clearance is too close, and will cause problems.

Almost sounds like your describing a neon srt-4? if so those things are pretty quick, if it wasnt, then dont ever race one until you get your problems figured out.
I would dyno it, a guy in the dyno shop could probaly point you in the right direction. if you do have 86 heads then get rid of them if you want to see any power.

It wasn't a SRT-4 maybe an SXT

As far as clearance goes, it's been running since 2000 like this, about 30k miles. Per the PO

Others are telling me to go MASS Air, the Speed Density can't handle this cam, not enough Vacum. SD would be cheaper and easier than going to a new cam and would be beneficial down the road. That's the way I'm leaning for now, unless someone has a reason not to.

Thanks,

Well I can tell you this. I had an E303, ported stock heads and a ported cobra intake and had my 88GT convertible running like a top with speed density.

On the other had I much prefer mass air.
