You CAN swap a HO long block into your Renix Jeep and keep all the Renix accessories except for the intake and exhaust manifolds. The runners of the Renix manifolds won't line up properly on the HO head so get the HO stuff. Since you'll be getting the HO intake manifold, get the TB to go with it. You'll need to lightly modify your Renix TPS to fit.

is there a write up on this, because there are a few suttle differences between the renix and HO engines. i am pretty much in the same boat geitin is.
