so i was recently presented witht he opportunity to trade my turbo ka24de 240sx for an e30 with an m20 motor running 16psi. My question is, what are these motors good for, 16psi, seem awfully high for a stock na motor. He has the turbo dynamics stage one kit on it.

They're stout motors, mine has over 400k on it. Not sure about 16psi, I'd trad though, a boosted M20 is a beast. Raw torque and power band.

Depending on if its got an ETA bottom end and head gasket/head studs thats about the top of what it can run. A stock M20B25 is only good for about 10psi depending on the tune. Many have run higher but it won't last.

The stock pistons are cast and are only good for maybe 330whp.
