SR20 Reliability Build Questions

not worth it. You'll spend more time and effort and cash putting forged pistons into an SR20DET just to have it fail (unless it's built by mazworx) than it would cost to do an OEM 2jz-gte swap and carry 470rwhp on pump gas with OEM internals and NOT fail.

forged pistons are great in theory but in my experience, due to the excess piston wall clearance and other engine building issues specific to the sr20det, they never work out the way you would expect.

And this is overlooking the fact that we are still talking 122 cubic inches. Totally not worth the 400+ power mark in a daily driver application. I would rather push 150+ cubic inches (or 350cid hint hint) and drive that 3000lb vehicle around. OR keep it below 340rwhp leave the oem internals in the 2.0 and keep it as stock as possible and drive it till she passes a ring.
