1)Look at the compression first...... New engine can get 100 KPA of compression, old engine that has 75 KPA still consider ok...... Last time Wood's engine reaches 50 KPA but no blow, he choose to rebuilt the engine wisely....... So he pay less...
2)Look for the air-fuel ratio, do a dyno..... 12.5 AF is considered normal, Amemiya's remap spec say 13.5 AF(but still consider risky, becos our petrol is low grade compare to Jap, easy to face knocking)...... 14 AF is
......
3)Check oil metering pumps condition, carbon can clog the hose...... If OMP not working, then no lubrication.....
4)Try pre-mix, it can help further lubrication..... Ask Goober for more info..... Some may not agree, but wth, i gonna do that later...
5)Rev it once a while to get rid carbon.....
6)Run in engine properly..... You need luck in choosing second hand car.....

With pre-mix, will it be more carbon or less or the same? It is my concern to try something out of the factory recommended way.

Well, I don't know how to rebuilt an engine. But put a used part together with new parts, the old parts will reach its life span faster than the new one. So, the next rebuilt will be sooner than an all new engine. So, you may save for the initial cost. But may pay more (2 times workmanship $$) at the end. If buy a new engine, any usable old parts can be sell for recovering some cost. Of cause, rebuilding the engine without changing any parts other than seals/o-ring/gasket is different story.

I agree with kean..... Rebuilts are very common...... Very seldom ppl buy completely new engines.... Not saying buying a new engine is not good.... of course if can afford its good, BUT...... its just not nessesary if all u need are 2 new rotor housings, apex seals, corner seals. side seals (if needed), overhaul kit (gasket set)......
And yeah, RE-Amemiya, Knight Sports, FEED etc etc etc all rebuild engines...... Its just more cost efficient.......
