If the revup engine has 300 hp, could I still use the plenum spacer for the revup engine if I dont have one?? Or is it specifically designed for tha engine??

 

It's designed for the 287hp motor. I have already tried. Same thing with Cams. Couldn't switch them out.

 

wait, now I' confused. Can someone go into a little detail about the plenum spacers please. I want one, I live ine New Orleans so it really only gets cold for about a month, so I don't think I need the copper one. I ave the 287hp engine too. Which one should I be looking to get??

 

If you just have the 287 engine just get the spacer.

 

wouldnt it be better for me to get the iso thermal spacer?? Just wondering. Or would just the spacer be god enough??

 

There's an iso thermal spacer for the revup engine, though it is more expensive than the spacers for the 287bhp engine. Just check the website http://www.motordyneengineering.com/350Z.asp

I'm thinking about getting one, but am waiting for some dynos comparisons like what was done with the other spacers.
