i dont know alot about them at all... i currently have the un pulley and a jwt pop charger, i was lookin for a new mod and some one recomended the Motordyne Iso Thermal MREV2, do i need a regular plenum spacer before i get that? is it safe for my car? any insight would be great.... thank you!!!

 

search. All you needs is a 5/16 spacer. No need for anything else.

The MREV2 is a modified lower collector of the one you already have.

 

you could also go w/ AAM's angled plenum spacer too:


here's the link to it

 

good mod to have, gives you some extra juice

 

Seems all the guys I know with Z's have the spacers and love them.

I would highly suggest it, from what I hear its real easy to do yourself also

 

I have both the 5/16 Motordyne spacer and the iso-thermal lower collector. Best mod I've ever done to a car! Not only can you actually feel the extra power, but the engines behaves better and pulls more smoothly than before throughout the entire rpm band, and revs more freely.

I'm on 93 octane gas always, so I haven't even had the dyno tune yet (waiting until I finish all my mods). Even without the tune, the whole engine feels "better." If you don't have access to 93 octane, you may want to go with just the spacer unless you plan on getting a reflash or a dyno-tune.

Furthermore, Tony at Motordyne is a true hero of the 350z tuning movement and a true advocate for each of his customers. Can't beat that.

 

Sorry but I am all talked about plenum spacers.

 

Props to you for starting another thread about the most talked-about mod on this website.

Clearly you haven't checked the top 100 questions thread, or searched, or seen the intake/exhaust rules. I'd start there if I were you, before starting anymore threads.
