Hey guys I am new to the G35 world and I keep hearing RevUp and NonRev up motors. I just got a 2004 G35 coupe 6spd sports package etc. Sow which engine do I have lol- thanks and sorry for the noob question just have always had BMWs!

 

you dont have Revup on your O4....i believe Revups are only on 05-06+ 6MT G35's.
someone please correct me if im wrong

 

you are correct

 

ok so I have the non revup---- what is the best mod for that engine? (plenum, mrev2, spacer, etc)

 

best mod meaning..
like HP/TQ wise?
spacer,intake,exhaust,headers etc.wont do much for Gains without a good/proper tune..
the only way to get the most out of our VQ's is to go FI

 

if you have any doubts, u should try wiki too..

the DE engines have one intake..

 

best NA non-revup bang for the buck mod is a plenum spacer (e.g. MD 5/16 spacer).

 

Best mod for a non-revup is the SEARCH option between quick links and new posts. Welcome to the thread and yes the MD Spacer is the best bang for the buck 5/16th or 1/2 inch your choice no difference really. Good luck
