Inside of a Buschur Racing engine with lots of abuse
I am not going into details on sleeving 4g63's, sorry. For those of you that would buy from me you don't have to worry, we'll do what's best for you. For those of you that won't, figure it our on your own

i cant see sleaving making much differance on the Evo. you are still limited to the cylinder spacings so you are only going to gain a very small amout of extra cc from doing it. also i think you could loose strength. that advangtage of the 4G63 over lets say a sleaved Scooby engine is the fact that the cylinder walls are actually an integeral part of the block. there are no joins or splits it all the same metal. you dont get this with ally blocks.
not saying that they cant be strong if designed right (have a look at the racing Ecotec motors!) but i dont see an advantage in sleaving an iron block.

Alright, my car is back together. Somewhere through the process of taking it apart and putting it back together I decided rather than freshening it up we'd put in a new engine since it was this close anyway. I've been wanting to run one of our aluminum rod engines and I had one done on the engine stand.
Also, I was incorrect on the mileage on the car, it has just over 9,000 miles on it, not 8,000. Not a big difference but wanted to be clear.
I have another thread with pictures of it put back together with the new header, Tial housing and new alternator. Good stuff.
Thanks for all the interest.

This first one is a picture of all four pistons that came out of our black shop car. This engine was in the car since October of 2006 through October of 2007. It was a 2 liter, has seen over 11,000 rpm, over 50 psi of boost. Quite a bit of dyno time, MANY track passes and this is what was in the car when it ran 8.88 and the 172.4 mph record MPH pass. The engine eventually split a cylinder wall (stock block not hard blocked). We took it apart to change the head gasket and freshen it up and found it cracked.
I can't believe how much abuse those have been through and the first thing to give was the Mitsu block.
