Who does end and center housing lapping at a good price? The closer to New Mexico the better. Just trying to get my rebuild started, and this is my only obsticle around here if you say you have a rotary to a mechanic they run away screaming and the funny part is that everyone that I spoke to has never even seen the inside of a rotary engine but all they can say is how hard it is to rebuild one. Any help would be great.



Thanks.

Out of about 50people that I have tailked to only one person had something bad to say about it, he basically put me down for wanting to build my motor, but I think thats because he did a botched job on his own, he also just did a sr20 rebuild and blew his new engine beacuse he did not break it in properly. I am no stranger to working on engines and have even helped rebuild a few and some of those were even rotaries, I think that if you are mechanically knowlageable it will not be a problem plus there are a few very good guides and DVDs to help you like the one from drift.com, that is probably the best one out right now.

Oh okay, on a daily basis I'm lapping stuff to .0005 but the stuff I'm machining isn't as big...and I'd prolly lose my job if they cought me doing it! Nice to know in theory I could possibly do it...
