K20A Block Compression

Re: K20A Block Compression
What do you mean by k20a base block? LIke k20a3?
Do you have a vtec head?
Rule of thumb, when you jump 1 whole compression point, that should be around 10HP increase if everything is done right.

Re: K20A Block Compression
No, a K20A3 doesn't have enough camshaft for 12.5:1 compression. You will pick up some power over a stock K20A3, but you need more aggressive cams to go with the increased compression to really make power. You will need a way to tune the engine... like KPro or something similar. The good news is that if you build it right, you CAN make a K20A3 base engine make more power than a JDM K20A Type R engine.
