So I am looking at buying a slightly modified 86 turbo Z.
The car has had the T1 converted to the T2 blow thru, with T3 rods and pistons, has +20's, and fwd performance ecu. My question is, how weak is the 525? I know they're junk compared to 555's and 568's, but I'd like to race it ever so often but I'm not sure how it will hold up to that combo. If it breaks, how hard is it to swap in a A555 or 520? I'm really wanting to get back into the turbo Mopars and this little car is slick.
