The GTP I bought has a spun bearing, she runs, but its kinda loud. Now the question is whats more economical. Having a shop, hone/bore and throw in some new rings, rods, crank and bearings. Or getting a used ebay motor for say $650-700 and eventually build up the old motor?

Id say the max budget would be 1000-1200$ for the time being, kids popping out soon so I cant go crazy yet.

If the shop route id prefer the shop to install the lower end, I can reassemble the rest myself.

If ebay engine, what models can exactly just swap in wise, I see compatible models but do they really just drop in?

One more thing, any sites that do sell a crank/rod/piston setup in 1 package?

P.S.S Is there a difference between the 4 door and 2door GTP's motor wise? Or will 4 door fit in 2 door and vise versa?
