I have a '87 2.5 turbo diesel, and well its slow. From 0-60 it moves like a snail! But after 60 it goes. I know it needs the k-1 spring replaced (jerk from 2-3) but is that causing the slowness? Also would seafoaming it help anything?

Slow? Its not a street light racer..

That said think Air in & Air out. It's going to get the turbo to spool faster. Is the wastegate or bypass "stuck" where the turbo is basically useless..

Have you checked the Turbo at all? (spins freely & easily) If so then continue to:

Air Filter
Exhaust Flow
Wastegate
Bypass

Sound like mine when I bought it. I bet you have no boost signal going to you ALDA on the top of your IP. Look at all your vacuum and pressure lines and check for breaks and leaks. Try to run a hose from the port on the upper intake to the ALDA.
