Especially the VET has VVL and is there anyone here who knows about subaru engines? can ypu giv their equivalent engines for these engines?

SR20VET although more powerful, it is rare and hard to find parts for. So it is easier to get the simpler SR20DET and make it stronger to take more boost and make more power.

If I remember correctly, JUN RACING has made 1000hp engines based on the SR20DET. They practically replaced everything except the block and crank.
