I purchased a 4g64 block and upgraded all the intervals to forged and am putting the stock evo 8 head on it. Just wondering what type of power increase I should see with the 2.4 compared to the 2.0 and with the forged internals

 

I predict torque will increase nicely......

 

Like they say there is no replacement for displacement.

 

Bore the 4g64 to 87mm and you will love the gains. This why we eclipse guys love the hybrid.

 

Or put a 4g63 crank in it , a set of long rods and make a destroyer 2.1l and be able to review passed 9k safely

 

Or build a 2.0 4g63 because it'll rev to over 9k without issue.

 

IIRC someone on this forum wrote that the stock oil pump cavitates above 8400rpm. Thus one would need an underdrive cog.
