Followed the link into here from Wiki. I am so new to this that I do not even have a Gt4 yet. I am looking at a couple of ST165 locally to fix up as a project with my son. You all seem to specialize in the later two gens, but thought I would ask for opinions. Both the cars are in good mechanical shape (CA USA, no rust) with the minor exception that both have blown motors. I know minor stuff. I can get my hands on JDM clips and motors at a reasonable price. Looking at the engine compartment has left me wondering how difficult it is to pull and replace the motors on these. I can see daylight in a few spots, not as bad as some cars (Ford Taurus comes to mind) but not like an old datsun or chev that you could stand on the ground inside the engine bay and drink a beer while working.

Do these need to come out the bottom or can they be pulled UP with minimal effort?
I am looking at JDM ST185 engines to drop in. Will these bolt up without too much effort? Can I convert to the air to air if I install a hood scoop? Should I skip the ST165 altogether because it is just... you know... undesirable?
I do have a fondness for overlooked performance machines, but I know that parts for cars like Honda are just way easier to find. How bad is it trying to find parts for the interior and exterior?
So as I said, looking for some opinons. Planning to buy this weekend if one of the cars looks good. FYI, prices are in the $500 - $1k USd for these. As I mentioned, interiors , exteriors are ok. The $500 one looks like crap after sitting under a tree for a year, the $1k claims to be very clean and covered. Figure if I can clean them up and install a $1.5k motor it should be a good ride with some resale value if we decide to move up or out.
My two bits.
