Im an indecisive guy, input swap vs boost.

[Kozworth]

Swap now, boost when that gets boring.

I would do this, but from what ive read the m50 does not really give that much gains hp/torque wise (mostly just newer technology and 'reliability.. I dont mind the m20 its reliable and easy enought to work on).

If I could find one, i would do an m30 swap but the issue is finding one that isnt overpriced or local..

I came across this site a while ago..

And I noticed that the 2.7 eta based stroker seemed to yeild a lot more torque and hp.. but when I googled I found a dyno that said it hit 150whp. So I do not know what to believe, because last time I thought that my m20b25 was atleast 160whp with the chip.
