Tips for the I4s

Long story short, I might replace my automatic trans. V6 with a manual trans. I4. I'm looking at a '90. Any tips as to what I should look for and what I should ask about? Thanks, Rupert

I think you may need a new ECU and new Wiring harness too.

If you really want a stick it would be cheaper to sell your current troop and buy another used one.

Oops, yeah, that's what I meant. I'm going to buy another Trooper with an I4 and a manual transmission. What should I look for?
