what year 2.3 engine are you using , I know the early ones had piston skirt cracking problems, which were know top also lead to high blow by , then later all the inside engine parts fitting loosely in a 5 gallon bucket , one cheep fix if you can find them is the old 79 to early 80,s turbo pistons , they had a carb and not fuel injection , they were 9 to one and forged TRW,s with the ford logo on them, put them in a baylner boat I use to have that came with the 2.3 engine , which use to eat pistons , ( at least the way I ran the boat, Fast and Stop ) that cured it and also used the turbo 2.3 oil cooler off the 84 up T-Birds , good luck on your next race ,
