At the moment my engine doesn't sound to healthy, as I can hear the big ends at start up, so it's still a while to go before I get problems with the engine.
Unfortunetly, I'm not too sure if it's the 7rib 4age or 3 rib...
About 1 year ago, I replaced the engine from a corolla... Not sure what the specs are on this engine, as the old MR2 4age engine blew up. (Alas, swapped it for the rolla engine)
What I have noticed though is that it doesn't have EGR system
(removed) and the O2 sensor has been cut (The one in the cast iron manifold, not sure if there should be one in there)
Hey _T_.... How much are you selling the 100Kw pistons for?
When you performed the piston swap on the AW11, did you have to do anything else to get it running? What size exhaust did you upgrade to.... Exhaust is something that needs to be done as well.
