I hink the mrev2 and spacer count as one mod in my book, since it is a combo. Isn't the mrev2 for the non revup engines and isn't the 06 MT a rev up engine? Also the stillen "cold air box" will give you no gains. Get a cold air intake (AEM, NISMO)

 

In that case, an exhaust and high flow cats are considered one mod, and headers and high flow cats just another single mod.

They're two completely different mods that complement each other VERY well. That's why its used as a combination very often.

True, the stillen airbox will not give you any gains, but you are worse off with a CAI (long ram). Long ram CAI tend to lose low end power, and will not yield any significant power up top. Point is, don't get an intake if your only concern is power.

And no, the MREV2 is considered a product for the rev-up engine, although it can be used with a non rev-up.

^^ what he said

 

yo soo, for speed would i be better off with cai? sri? or pop charger wit z tube?

 

why does everyone go with 5/16 wouldn't 1/2 be better? especially when going FI?

 

tell us if you feel a difference once all this is installed!

 

+15 lbs of torque makes the MREV and spacer a very good mod by themselves.

 

Most go with the 5/16" spacer because everything still fits and looks like stock and it makes a slightly higher average power.

The 1/2" spacer will make a little less TQ but it will make a little more HP at the top end.


If you do road course or drag racing, get the 1/2" spacer. Otherwise, its best to get the 5/16".

 

Will you get the max preformance out of the spacer if you are running stock exhaust.

 

It pretty much makes the same gains on fully stock or fully modified cars.
