There are 4g63 wideblocks and 4g63 Narrow blocks. The only known KM132 that has a narrow block bell housing pattern came off a 2.0 MightyMax/D50 all others use the wideblock.

All Turbo DSM's 90-99 use a Narrowblock 4g63. As long as its turbo from the factory then its a narrow 4g63. But to make your life eaiser you will want a 90-92 4g63. The other years use a 7bolt motor which is proan to premature crank bearings.

Did it NEED to be a AWD DSM?
No, but all awd dms are turbo. There are front wheel turbo models as well. The 90-94 were called GS Turbo where as the 95+ were called GST.
Keep in mind after 1992.5 the 4g63 narrow block were 7 bolt motors. Meaning the six bolt starion flywheel will not bolt to the crank. If you were looking for a factory turbocharged 4G63 I'd be on the lookout for a 1989.5-1992.5 Mitsubushi Eclipse, Eagle Talon, Plymouth Laser. It could be front wheel drive or AWD I just wouldn't pass em' up in the u pick it yard. Like you said it's pretty easy to tell between SOHC vs. DOHC. Pop hood...Nope. There are other models, like the Galant VR4, that had the 4G63T but, I have no info on them. I try to keep stuff as simple as possible and those cars are pretty rare in my neck of the woods so I don't even spend time looking for them. I may have passed a few up a not even known it.
Also the SOHC to DOHC swap seems fairly simple. DJ's laid it all out for us. About the only advantages for finding a turbocharged narrow block engine is for the oil squirters and reinforced main caps. But even those can be bought and added.

The 2.4's are wide, the 2.0's are BOTH unfortunately from what I have seen int he junkyards-you have to visually confirm it.
As far as someone building it-I will gladly someone point me in the right direction to an R&R+ a stronger base plate-because I will be making at least 500whp as soon as the car hits the streets. On the dyno- I will turn it up past 7XX and see if it holds if Im confident of it.
The tranny I just picked up is in good condition. There is some input shaft "side to side" play, but I dont know whats acceptable. It feels as much as the RX-7 Tii trannies I have had. Would the pilot bearing take care of this slop?
