if i were to look at the car, i wouldnt spend over 2k. If it was in perfect running order i would consider purchasing it for between 3-4500 depending on overall condition.
Also flashing cel = cat.
a nice and clean gsr can fetch 4500+ in the right areas. The door handle is easy, just rekeying it might be work if you dont have someone to do it for you. the door handle is 2 bolts and you thats pretty much it.
they are modeled after the ITR manifold, so most likely slightly bigger as the ITR was ported and polished from factory. But i dont remember my hondata gasket being bigger than the ports.
TB bore is the same on the OD. Location of the throttle body is a lot lower. Thats why GSR intake arms are longer...
itr arm is too short for the gsr intake.
good luck trying to find an OBD1 p72. I would switch to a 1st gen skunk or blox manifold which are ITR styled ones. if its smog you are worried about, skunk2 pro is carb legal.
everything works if you run an obd1 ecu. except the butterflies, those will not open if you dont use an obd1 p72.
I have a virgin p28 for sale if youre interested. Its the preferred obd1 ecu. Shoot me a PM.
caster isnt a wear angle and doesnt do anything to the handling if you have a caster split like that. I track with a caster split thats bigger than that. I wouldnt worry about it.
