This time the engine will be built with Crower rods, Pro Mod head studs, cometic head gasket, new cam chain, all new bearings/seals and a fresh valve job. It will be bullet proof as long as I don't let it detonate again.....Detonation will kill any engine..... If I put straight race gas in it to keep detonation away, the engine will support 450-500hp.....

maybe you were confused when I said a "blown" engine would haul a$$??

I didn't literally mean "blown", you know..

tagging along for update pics. going to pull apart my old engine (2000gsxr600) and get everything mic'ed and make sure everything is in spec before replacing bearings, cam chain and any other "expendable" parts.

Should make a pretty sweet go cart/buggy engine. Althought i may be better off selling it and using something with more low end torque...like a V twin. But rebuilding the motor is just for fun anyway.

ROUND 1 of goodies showed up.....

First wave of parts came in today. I can at least build the shortblock this weekend.....

Pistons....the other white meat???
Pistons....the other white meat???
Pistons....the other white meat???

The freshly rebuilt turbo should be in early next week. I found out the head is worse then I thought, all the exhaust seats are cooked so its getting shipped to Indiana for a full rebuild and Serdi valve job....

Stay tuned, saturday I should have a pic documentary of the lower end build up.

ok... I am not familiar with water injection.... is this direct injection of mist into the air box or water spray onto a intercooler to make the charge air colder and more dense?

Yeah its very high pressure, 100psi, spraying in a small jet that atomizes the water/methanol into a fine mist, its injected into the up pipe right by the turbo. Bascially is designed to cool the incoming charge as well as cool the chambers. During combustion, this water vapor expands and cools everything, its main purpose is to keep detonation down, thats what causes the melt downs. You can mix water and methanol and gain a cooling effect which "could" make more hp, or run straight water which has a better cooling affect and helps keep detonation away....thats what I am going to do. The whole thing is mainly an added safety feature to help protect the investment I now have in this motor.

Only under boost, I will trigger it to come on at 8lbs of boost, I normally run 10lbs. If you notice, I ported the hole on the turbine housing, thats the wastegate port. I ported that sucker out to a full 38mm(to match the wastegate piping) and that should help keep the boost creep down. I was getting about 2-3lbs of boost creep, another factor in the melt down. Now it "should" hold right at 10lbs which is the absolute limit for 93 octane and low compression. Water injection adds to the safety limit. It should make 250rwhp reliably like that and I shouldn't have a problem running it out in 6th gear(although I won't try it again on pump gas). Then when I turn the boost up to 17-18lbs on race gas, it should make 300-320hp....the turbo is out of steam then.
