4G63 vs 4B11 what are the difference?

Oh hai, you're a Tomei dealer. /ubbthreads/images/graemlins/smile.gif

 

it is in depth and answers all my questions!

I believe there was an evo x over on evo m that made 670ish whp on an internally stock engine so I believe the 4b11 is going to be quite worthy. Since when has Mitsu downgraded?

Here is what I have found after driving my RA for 6 months.

Mitsu has really tightened up the ECU programming so that you can't mod anything without reflashing.

The MIVEC head is noisy. When the motor is at full operating temp, the valve train rattles. (the dealer say they all do it which I call BS but I don't have anything to compare to).

Other than that, I would bet that the 4G and the 4B stock turbo blocks w/stock internals will handle about the same power.

Well combine the puck style shim over bucket lifter with crappy mitsu castings and I would say for sure the head will be noisy for sure but nothing that could be fixed with 8-12 hours of lifter reshiming /ubbthreads/images/graemlins/uhh.gif
