will 2g gst cam gears fit on a 420?? I'm pretty sure they won't but wanted to ask just to know.

While the subject is up tho, what all is interchangable between the two motors if anything??

 

only stupid question is the one you don't ask.....
cam gears are different,actually nothing is interchangeable between a 4g63 and a 420a,except for universal stuff,turbo,boost controller,gauges,etc...the 420a is a chrysler motor,the 4g is mitsu

 

Well I knew the motors were made by the two differant makers but thought it was worth asking lol

I just barely started learnin my honda before I swapped to eclipes, so I'm still learnin here
