yeah, i'm on the old gte rid of those bloody turbos bandwagon too. if you just paid $300 to get one rebuilt and you're willing to do it for another then that's $600 that could have been used on a more effiecient and appropriate turbo for what you are wanting to achieve.

if you go forged pistons you're up for a grand, but so far you haven't had any piston probs, even with big boost pressure. rings may be just old, and compression can't be too much of a problem if you've been hammering 14psi into it.

reuild a motor to stock, at least you know the bores will be honed and new rings are doing the sealing.

save the money from the forgies to buy a fully programmable computer and 'sort out' your turbo issues, whether it be runnning them within their efficiency range or replacing them with bigger thems or an it.

the a15et(t) has plenty of potential!
