Yea the gouge has a lip that i can feel with my finger nail..Not terrible but i wouldt feel real safe about it if i didnt bore it out.Will boring it out 0.20 over up my compression much?SupraDupra500 said:can you feel the "gouge" with your fingernail? some vertical gouging is normal from thrust. i built a 7m without boring it and got away with it. some you can hone out. i did that. but some DO have to be bored out.. i just honed the hell out of the cylinders.. thats just because i HAD to get the car running. i suggest taking your time and bore it

What are your horsepower goals?
A lot of people will just take the 7M-GE, put on a fresh headgasket with ARP hardware, GTE ECU, necessary turbo conversion parts and go from there.
You can run a pretty decent amount of boost and put down some respectable horsepower.
Again, it's all just a matter of what your goals are for this motor!

I live in the Indianapolis Area and I have had my '89T (stock) for 10 years (I bought the car with a Salvage Tiltle from Brickyard Imports in Brooklyn, IN). I rebuilt the engine when I got it and have never had any head gasket problems (then again I am running the stock CT26). I love the car and its alot of fun to drive. As long as you do all the work correctly and don't cut corners, you will not be disappointed.
