Got my gasket set and don't know what to make of this. The head gaskets are both right side. Is this wrong should I return it for the left one or flip it around and run it?????

I have my answer to the head gaskets. The fel-pro tech said and I quote(Flip the gasket for the left side just make sure the arrow points to the front of the engine.) So engines going back together just fine. Decided to go with a different M-62 I pulled from a car at work. Much cleaner but ??'* injectors are bigger and it has a 70mm TB, I have a 56or57 mm for it now. What are the advantages to having bigger injectors and TB?

more fuel and more air entering the motor... as long as its not too much and the computer and handle the difference you should get a much better response and some added power this way... will be a lil lower on fuel efficiency but hey... whats power without a price... you may if possible consider getting it scanned for KR and/or getting it tuned once up and running

what year is it off of??? that could be the reason in the difference

Hey, you've got quite a project! If you leave on the supercharger and injectors from the 92 engine, everything will work just fine given that it'* hooked up correctly. If you use the newer supercharger, the one that 94-95 SSEis had, you will need to get a new tune put on your PCM. You need to contact Sinister Performance if you'd like to use the bigger supercharger.
Sinister Performance, LLC.
The owner is known as Darth Fiero on a lot of 3800 forums.

The question of Series 1 to Series 2 part interchangeability was brought up. The article for installing a supercharger on an NA engine doesn't cover the Series 1 because it'* so different. It doesn't use OBD 2 with which we're familiar, and most of the engine shapes and sizes are different. Look for turbocharged400sbc on this forum and on 3800pro.com to see the Series 1/2 hybrid that was started. They tried putting Series 2 heads on a Series 1 block, but that'* where they stopped. You need a custom LIM because the heads are so different in design. Pretty much nothing swaps over directly, but with plenty of cutting and welding I guess anything is possible.

You have a really cool project. I suggest for simplicity'* sake that you stay with the 92 supercharger, but you can go to the 94-95 version with the bigger throttle body if Darth Fiero can burn the proper tune for you. Tuning a Series 1 is much different from a Series 2 because the OBD 1 system needs to have a chip burned with new info as opposed to the Series 2 simply getting a new tune via the OBD 2 port. It'* only difficult in that you need to get a tune burned to a chip, but I guess nothing should be hard for you with all the awesome work you've done so hard. Once you jump that hurdle, you should be set tuning-wise and ready to start the engine.

Did someone mention my name like a month back?

Search on "Frankenbonne" for some insight to a similar project done in the past. (In my garage, I have pretty good knowledge of it).

First issue I see is possible wiring harness/connectors/pcm. The 91'* pcm will not be programmed for boost and fueling of it.

The TA mount on the passenger side might not be a problem. Pull your coolant tank and see if the holes are in the body. They were in Frankie'* case.

You are cruising.

I'am stuck on the TB becuase of the gasket I pulled the supercharged from a 93 SSE. I'm not sure what year this whole setup even came off of. Every gasket the local gm parts place had was for 96 thru 99. Couple more trips to the auto parts store and I'll get it. I read someone say 94/95 this I will try. THX Everthing else is great with this project have not gotten to the hard parts yet but soon.

Yeah, go to any local parts store and get a 94-95 throttle body gasket.

Well nobody here in town has the TB gasket for my app. Anyone know where to get 70mm TB gasket for 94-95 SSEI online? THX On a more positive note Today I pulled the motor from a 93 SSEI with 49K original miles took the engine wiring harness, motor mounts, tranny, supercharger, headers & axles with me. Ends up the engine had a huge hole in the side of it. But everthing else was fine, no play in the pulley on the */C and tranny is already remaned will take the GM reman #* and try to get more info on miles. I think this trans needs a shift kit and stall for my project car.
