M20 Turbo => M50 turbo fun.

That's even a lot for a stock m50, and they handle boost wayy better.

Going a new direction! Swapping in an m50. Anyone wanna buy a m20 with 128k on it? Also hooked to an auto trans so it was never over revved. Getting a m50 with 135k on it. Hopefully I don't have to replace too much. Too bad I just spent a bunch on money on that damn m20..

Why the change of direction? I love me some M20 but mine is healthy at the moment. No need for another one yet, otherwise i'd be after you about it.

I get easily persuaded I think.. The m50 is more modern and parts are easier to find I guess? And I figured if I'm going to spend a bunch on machine work and stuff to have a decent motor, why not just start with the m50? I don't know. Tell me why not.

Your logic is definitely sound.
It would be silly to try and say the M20 is a better engine than the M50 but I think the point at which my jimmies become rustled is when someone has an M20 in a poor state of tune (see also too cheap to hunt down vac. leaks and replace old parts) swaps in a junkyard M50 and pretends the M20 was a total un-fixable pile and the M50 is a rocketship, when in reality, a tune up would have likely yielded the same performance increase.
One thing to keep in mind about the M20, is that in NA form, it was a very highly optimized engine for its day. The LS1 is praised for being such an optimized engine with only 2 valves per cylinder, but when you do the math, the M20 has a specific output very close or equal to that of the LS1 (depending on the version of LS1) and that is with an archaic EFI system and relatively low compression ratio. Being reasonably optimized means that there is not a whole lot to gain unlike a 350 chev with 190 hp which gains 100hp with a carb, manifolds, and a cam.
So yes, the M50 is a more advanced engine, has more area under the torque curve, is more refined, and capable of making more power with less sacrifice down low, but the M20 aint a bad gig either, especially when the cost of replacement is so low, especially when your snail-obsession gets out of hand.

if you are like this guy and know what you are doing
you could have yourself a reliable turbo m20 with little lag that screams on the track.
A turbo M50 will make a little more power with less boost than an M20 and might be the better choice if you want to keep the internals stock.
If it were me I would probably do the M20 just because I feel that if the heat of the turbo caused a cracked head or if the bottom end blew out, another healthy M20 engine could be dropped in for hardly anything.
