How difficult would it be to swap the 1G 4G63 engine into the 2g Eclipse Rs? Would it bolt up to the 420A's transmission or would you need the 1g transmission? What else needs to be done? I searched a little but i dodnt find much.

 

i beleve you would need the other tranny becuse a 4g63 sits assed backwards from a 420a. so the motor mounts would have to be moved. and you would need a new ecu as well there is alot of work to swap. it would be easy if you could get a whole eclipse that has ben smacked in the rear but everthing up front is fine. it would make it alot easier.

 

The only reason Im asking is cause I wanted to get a 2g eclipse but the GST/GSX are very expensive here so I was going ot get an rs and swap the engine in but I might get a 1g instead or Ill deal with it and pay more for the Gst/Gsx. I have always wanted a Gsx so maybe Ill just go that route and spend more money on an upgraded turbo.

 

the best way is get a totaled 1g that the rear section is gone than swap everything. you might have trouble going from obd2 to obd1 some states will fail the emision/inspection if it has been changed from obd2.

 

any swap to an older motor is illegal for emissions. Go buy a turbo eclipse and save your money and time.

 

how is it possible for honda owners to mix and match and swap all sorts of engines into there hondas. Newer and older hondas.???

 

No not really. Hell I've seen Hondas with the 4g63 swap and I've seen Mini Coopers with the 2.2VTEC swap and still pass emissions as if it were stock.

 

the only thing that woudl be illegal is the visual inspection for having a different engine but the dmv can issue an engine swap as legal right? Or if its converted couldnt I do the smog myself and jsut write it down as visual passed?

 

yes its still easy to pass emissions because they cant easily diagnose that your motor is swapped, however, it is a fact that it is illegal to swap an older motor. I have a 6bolt myself and will never pass emissions visual because i have dangling harnesses.

 

people swap on the 6 bolt for the 7 bolt is that still an illegal swap?
