that an ok size for running a full exhaust set up? and what does the diff in size really do?

A 75mm is more than enough. You should be fine so long as you stick with a name brand.

A larger t/b reduces the restrition in the intake tract, so the engine makes more power. On a bolton only n/a setup you will only see 2-4 RWHP at the most, but most people claim to get a better throttle response.

That is a t/b and inlet plenum, and one hell of a price too. I have the BBK t/b and a C&L plenum, but the BBK one should be fine, there is not much they can do to screw it up anyway.

does a t/b and plenum help more if you have nitrous,,,,

If you have forced induction, you will probably see higher gains than if you were N/A.

how much do they usually cost,,, i should prolly just stick with getting 4.10s b4 the t/b and plenum right..???

so1o2k3

yeah get the 4.10's. I think a decent set of T/B and Plenum would cost around $300.

ok ... i will have to get the t/b and plenum later down the road,,,,after the 4.10s
