Looking for performace parts

[Challenger266]

I have a 87 300zx non turbo. I am looking for aftermarket oversize cams, having a hard time finding them at jegs or others like that.

Anybody point me at a better source?

Lots of good Z31 specific cam info here http://www.xenonzcar.com/z31/camspecs.html The Z31 is kinda the redheaded stepchild of the Z family, even though it was the best selling model, not much aftermarket support. If you want more go out of an n/a your best bang for the buck is a turbo swap or turbo conversion. The turbo was 190 hp stock, 30 over the n/a. Add an intercooler and boost controller and you can hit 250+ whp. Upgrade the turbo, injectors, head gaskets, head studs and 400+ whp is attainable.

MSA (zcarparts.com) for most things Z Car
Certified muffler has the Z31 exhaust market on lock
