Anyone know what a running 4g63 engine is worth. Maybe buy a used one but don’t want to over pay for it.

4g63 is interference. Valve damage depends on how far it jumped. Are you looking for a 4g to replace a 420?

i guess I still learn sum everyday still ha haThat's about right, and 4g64 in the NT spyder... but Mitsubishi built other cars... and Hyundais used mitsu motors for a while also, so you'll see them in various configurations... the 4g63 is kinda like Mitsibishi's version of the Chevy small block - around for years in a bunch of different cars and configurations.I thought it was only 420a and 4g63’s atleast for the 2G’s

<edit> And I think the 1G used a NT 4g63 instead of the 420a (but that information can be found on this site somewhere)
