How many of you have blown a motor? - from Honda Tech with 35+ posts on blown engines/trans from turbo's....
For high boost (over 15psi) you will need (unless your car's basically new)
White Smoke
White smoke out the exhaust, does not always mean a blown head gasket. Which some fools are to stupied as not to beleive it... However trying to convience them differently, is like telling somebody that something is hot and will burn them, yet they will still try to feel/pick-up it. It can be caused by the engine running a little to rich (especially if seen in boost) or from a bad sensor. One example is when running N2O, and the extra fuel that is added when it's been activated. N2O is odderless and coloress so it cannot be causing it. This is also a visual clue when someone is using it. When I had the supercharger installed, I was told that I should be seeing a little white smoke too when in boost. I also saw an HF with a bad dist., it had white smoke pouring out of the exhaust, until it was replaced. When adjusting the fuel pressure on mine, it to will have white smoke out the exhaust at idle if it's set a little too high.
Fuel & Ignition
High boost engine, you are going to have difficulty making it run right without an aftermarket fuel/ignition management system; basically a new ecu. These are available from a variety of sources, like Zdyne, Electromotive, and Simple Digital Systems. My knowledge is from research instead of experience, but I would just about guarantee this is what anyone else will tell you.
Turbo Wear - posted by: integracon
Unless it's EXCESSIVE shaft play, there is really no way to determine it's out of tolerance without using the proper tools.(ie. taking it to a turbo rebuild shop). Your talking thousanths of an inch here or there. I had mine rebuilt and by just using his eyes and jiggling the shaft back and forth the Turbo guy couldn't even tell until he put it on his machine to measure it.
The best way to "quick check" excessive shaft play is to see if you have any
scorring on the housing. Since the shaft spins so fast, any excessive play will
cause wobbling and should show on the housing. Again, mine was so close, I had
no scorring, just bad boost response.
MAP & Check Valves - (Code 3 or
5)
A check engine light will appear if the stock map reads anything over .08psi. You can use check valves, just simple aquarium check valves, three of them should do it. Or, you can go with a "Missing Link", however I have read/seen posts, that they are not very relaible. Peeps were still throwing MAP codes occasionally.
