When you add a turbo (or a SC) to your stock honda engine, there are really only 3 things that can happen to cause your engine to blow up.
1. Running Lean: If you run lean, it causes the air/fuel mixture to burn hotter, which, under the right circumstances, can melt pistons(which will cause a whole shitload of other problems in ur engine )
The solution: use 440 cc injectors, a hondata, and GET YOUR CAR TUNED PROPERLY
2. Preignition: Preignition is when the air/fuel mixture in your engine explodes prematurely due to the air/fuel mixture becomming too hot. Engines that are turbo'd or have high compression (10.0:1 or higher) are at high risk for this. Its caused by a variety of factors, the biggest being ignition timing, fuel grade, manifold air temperatures. If your car pings because of preignition, your are likely to blow a hole in your pistons.
The solution: Use the highest grade fuel possible, retard your ignition timing by .5 degrees for every pound of boost, and GET YOUR CAR TUNED PROPERLY.
3. Bearings becomming too hot: When you add horsepower to an engine, you are also adding to the pressure put on the bearings that sit between the crankshaft and the rods. When you add pressure to the bearings, you increase friction, which increases the temperature of the bearings. As you should know, the crankshaft is cooled and lubricated by oil. If the temperature of the bearings on the crankshaft exceeds the boiling point of your oil, all hell breaks loose. The first thing that happens, is all the oil boils off. Within milliseconds of your oil vaporizing, the crankshaft essentially becomes welded to the rods, which, in a matter of a few revolutions, WILL bend/break rods and probably throw some of the rods through your cylinder walls. Regular oil boils off at about 350 degrees farenheit. Good synthetic oil boils at about 550 degrees farenheit, AND lowers the has a lower coefficient of friction, which in turn significantly lowers the amount of heat that is produced in the first place.
The solution: Use high quality SYNTHETIC oil in your car. If you are dumb enough to turbo your engine and still use regular oil, you are going to end up with an engine that looks like this:
Notice what the bearings look like?
Honda does two things that makes their engines last so long (400k if taken care of and not raced).
1. Honda builds the engines to exact tolerances, meaning, they put everything exactly where it should be, and not a micrometer to the left or right.
2. They overbuild their engines...they make them so they can withstand levels of stress which they will probably never see.
If you make sure to use good synthetic oil, high grade fuel (103 octane race fuel if you boost over 6 psi), and get your car 'tuned' properly, you will have no trouble boosting your motor a reasonable amount.
my friend has bought a turbo kit from that site and was boosting about 8 or 9 psi no prob on a 3rd gen lude. all he got was a fmu not a new fuel pump and his car is the almost the same as the owners of that sites except that his car is a auto. tom the owner of that site know s what he is talking about... i trust him!
