I wouldn't do it yourself then. I've rebuilt a VW bus engine and worked on several bikes torn apart, but i'm not sure i'd be ready to tackle my 4g63 just yet. A turbo kit is MUCH easier than rebuilding a block. Its all pretty much bolt on vs. actually having to measure precisely. The hardest thing with a turbo kit or swap is getting the old bolts off and the new stuff to fit...

but if you have the time and patience, do it! The amount you'll learn from it is well worth it! :thumbsup
