Hello,new guy to the group, picked me up an 86 MM. got it for a good price as it had sat for near 20 years in a barn, yup, a true barn find. got it home, did all the usual things required to bring it back to life. got it running and it ran very well, smooth on all 4, nice idle etc. but it smoked,,,, alot. tried all my tried and true methods to release the stubborn piston rings, but no luck. decided to just get a rebuilt long block,, seemed like alot were available and the price was OK, so ordered one and removed the anemic g63b and took it apart to ship back the core. while waiting, did the needed bodywork and painted it the original r52 california red, wow,, sure is red lol. after a bit of waiting,, called to see where the new long block was,, was at that time informed there is no sure thing,, anywhere. called all kinds of other rebuilders,, got the same answer.. so,, took old one apart, saw it was not too bad inside, bought standard rebuild kit and replaced all pistons, bearings, seal etc. any wear items, and pumps. reinstalled, weber carb upgrade, runs great, but must have worn out more then it looked cause it only has 20 lbs oil pressure at hot idle. that didn't freak me out as much as finding out there is like 0 hotrod stuff for this motor. so,,, looked at all the swap postings on here, knew i could do the 350 chevy swap, but it had alot of knit picky issues that would delay things, and I kinda like driving this cool little gocart. looking around at the 4g63, but not any around here that i liked, all 7 bolt, high miles etc. Then,,,, found this. a guy parting out his 91 eclipse gsx. got rear ended about about 1000 miles after he built this motor:
Engine- 6 bolt bored 20 over with wiseco pistons, h-beam rods, ACL bearings, ARP hardware, cometic head gasket, mild ported 1g head, BC 272 cams, BC springs, adjustable cam gears, all new gaskets and seals. Pte 50trim journal bearing turbo w/ stock dsm houseing, tubular manifold w/ external dump, turbonetics wastegate, turbonetics BOV, forged manual boost controller, 3” turbo back exhaust, big FMIC, AEM wideband, fuel lab fpr kit, 255 pump, ETS 1000cc injectors low impedance, evo 8 ecu, 4bar map sensor. and a cutdown harness and 2 more complete harnesses, including fuse box. i do believe this is over kill for my poor little Mighty Max, but,, its mine now need to do all those things needed to install, hardest being the intake,, but i have just enough skills to pull it off. have already found this site to be extremely useful, and will keep all informed about the build. wish me luck and thanks for adding me to the gang. Thanx,, Mike
