I`d like to hear your opinion:


An 03` 6sp Z has a UR flywheel, and some weight loss. What would be your choice for the next piece?

- AAM angled spacer
-Motordyne spacer (1/4`` or 3/8``)
-KJR crank pulley
-UR pulley
- Crawford Plenum
-leave it at that
-other

I`m looking for a modest (realistic), but noticeable gain in performance - as I received from my flywheel. Longevity and no headaches are also a priority.

I`m thinking the spacers are a good bang for the buck, but I`m wondering about leaks.

The plenum has a higher price on it, but has a lot of positive feedback. Would it help much without any other breathing mods? (this could be asked of the spacers too).

The pulleys seem logical b/c of the flywheel already being light. More revviness than ever.

What do you think???

 

I have the Motordyne spacer and couldn't be happier. No leak issues ever nor now after a few thousand miles.

Good luck

 

If you want to experience noticeable gains by a single mod, putting headers on is probably one of the best NA mods you can do. Butt dynos from around the world have provided proven gains that are sure to make you smile! ;o)

We are currently running a special on our Strup headers:
