I know this might be a dumb question, but what will give me more enjoyment out of my Z. I have an automatic, would the lightened crank pulley or high flow cats/ testpipes be better. I plan on doing both, but only have the money to do one this month or until after christmas. I am considering bang for the buck and sheer response/feel.

 

bang for the buck, go with testpipes. first get some type of intake, spacer then testpipes. save up and get all three.

 

TP's will yield more power, plus increase throttle reponse. The only drawback is the nasty smell, so if you can withstand the smell of unburned gasoline then you should be okay.

When I installed my KJR crank pulley, I didn't feel a thing.

 

I believe i was told to go with the MREV2 rather than a spacer, should i be getting both? Are the gains from these two items noticeable?

 

Is that the pulley that uses the stock belt?

 

UR Crank Pulley, 5/16th iso thermal plenum spacer, MREV2, HFC/TPs

edit*--actually you have automatic--dont get the plenum spacer

 

No space since its an auto, may i ask why? or does this have to with rev-up motor vs non rev-up

 

revup--non revup

 

Yeah its the stock size, I didn't want to damage the accessories.

 

+1 I like the sound of TP.

 

Hfc/tp.

 

Can someone pls elaborate, why is spacer not appropriate for 5AT?
I was in fact thinking of getting Motodyde 5/16 Isothermal as my next mod for my 5AT Touring, since I alredy have Popcharger, Crawford HFCs and alluminium pulleys.
