Im thinking about about buying the Mrev2 and i have a few questions.

1. should i go with the 5/16 or 1/2 and whats the difference2. iso or reg?3. will the stock crossbar fit over the the mrev2 and new spacer?

1st off be sure that you have the Rev-up lower collecter (easy if you redline 7k rev-up/6600 non rev-up) I think revup collector came in 04 1/2 if you dont have the rev-up just get the 5/16" spacer.

If you do have rev-up Go 5 1/6" spacer AND mrev2 lower collector the 1/2" spacer doesnt give enough increase to justify the extra money the 5 1/6" is better bang for buck and if you dont get the MREV2 lower collector you will just be wasting your money.

The "ISO option" is a Gasket (Isothermal Gasket) it helps with heat soak you could really go either way on that for the money depending on what youre trying to do its a $50 difference for probably minimal gain but it cant hurt.

Pretty sure the stock strut bar still fits. heres a handy linkhttp://motordyneengineering.com/350Z.htm
