Ok here is the idea i had. to get 400-500 hp. now in increasing the compression by shaving the head how much can you shave it with out the engine not working or what the recommended is? second is if i put all new valves and valve spring or even over sized with over sized pistons at .20 or .40 can achieving at least 400hp on the 7M-GE be possible? the guy at suprastore.com said its not.

Im in the process of restoring an 87 supra with the 7M-GE engine i live in IL so it the only one i can find and i dont really want to go through the problems the turbo can cause plus it will be more of a cop magnet lol. i was going to go with a 3" stainless steal blitz exhaust. a cold air intake as well. a 144 amp alternator, 550cc fuel injectors and a 255lph walbro fuel pump to back it up. also the guy at suprastore.com said the most i would get out of the engine is maybe 265hp. i dont think that sounds right is the GE and the GTE that different i thought it was just the added turbo getting ride of the distributor the arraignment of how spark plug wires are run and the 3000 throttle body.
