Thanks guys

Hey out of curiosity, I was wondering what would happen if I rebuilt my EA82T with non-turbo pistons, and put everything back together as if it is a turbo, but disable the turbo (remove impellers?) so that there is no boost. Would the timing or anything be affected such that the car would not run well or else fail CA smog? I appreciate the honest feedback from the Subaru gurus out there. Thanks.

Thanks. I'm actually planning to ditch the turbo and need to decide which block to use. The 86 GL block has been decked enough that I will have to use HG shims.

Hello all, I'm trying to rebuild/replace my EA82T and have read on here that the blocks are the same. Hence, some confusion. Below are some pictures. First, a picture of the EA82T block from my 86 GL10: Second, a picture of the block from an 87 XT (non turbo MPFI) engine I bought from a junkyard What is the extra cavity for in the GL10 block? What can I get away with? Third, a picture of one of the pistons from the 87 XT engine. I has been bored 0.5mm over. But this looks like an "interference" design to me and I thought all EA82's were non-interference? Does anyone recognize what these pistons are from? thanks much for looking and providing some help. I hope these pics can be enlarged somehow at least when viewing....

Subaru rookie here, looking for some guidance. My story: last year bought a 1986 GL10 4WD Turbo wagon for $300. California car, body straight, paint is good, interior is good. Seller had bought the car with blown head gaskets, pulled the engine, tore it down to short block then decked the block and machined the heads. The engine had gotten hot enough that the timing covers melted. OK so I checked the pistons at their highest point and they protrude past the block 0.020-0.025". Seller told me I could get custom thickness gaskets from Cometic. Saw cracks in the heads between the valves, so I pulled the valves to investigate further. The cracks in the worst case are at least an inch deep, and go to within 3/8" of the seat. Junk, so I hear. Searched for replacement heads, reman, whatever and looks like could cost me $500. Contacted Cometic and since they don't have dies, they can't make MLS gaskets for this car, but with dxf file or gasket samples they can make shims from copper. I am not stuck on keeping the turbo. I just want a decent stock running car. This thing is going to be used by my kids in a year or so. I live in California and do NOT want to deal with the smog referee. "Been there done that" when I put a GTI motor in my vw caddy, and it was a nightmare. Seems like the simplest thing to do is find a non-turbo MPFI motor (best case), or else a SPFI motor, and put it in. Can anyone tell me if this will cause any trouble with normal smog check in Ca? If I switch to non-turbo MPFI how much wiring or ECU change needed? How much more wiring/ECU changed needed for SPFI? I saw reference to GD's writeup on swapping to SPFI from EA81 etc and would like to see that but can't find it. Can someone point me to it? Thanks in advance
