TPI Swap
Just bought a L98 from an 88 IROC and I'm gonna swap it into my LG4 Z28 5-speed, so i have a couple questions...
1.) L98s were all auto's, so what all do I need to switch on the Rotating Assembly to meet up with a T5
2.) 1988 was a MAF year correct? Cuz I need a air filter box and wiring harness still.
3.) Will the Stock Computer from the IROC work for my 5 speed or not, or will i just need to switch the PROM?
Thanks for the help guys.
