Talk about cheaply turbo-ing a 5sfe, BADDDDDDD Options

at least its a 5th gen owner.

Wouldn't it be hard to run 10psi due to the engine running bad when not boosting? The timing would be hard to figure I imagin.

why would engine run bad while not boosting? i assumer youre talking about restriction of compressor blades. well if properly designed it should not provide a large restriction. however it will be more restrictive, and since we dont want a really slow car under normal driving, were planning on powering the motor continuosly from alternator(at a lower power) during normal driving (to provide around 0.5-1psi of boost). we thought of using a bypass valve, but thought the other idea to be much better and simpler. i dont get what your trying to say about timing.

No, I'm talking about how the car adjusts the the amount of air going through it. I just figured it would screw it up to have the on and off again high levels of boost. I think it's more than workable on low levels, but I don't know about high levels. It just seems like it would run weird. I don't know though.

why would it screw it up? the engine management responds to incoming data in milliseconds. even conventional turbocharged cars arent always at high boost (or boost at all). i assume youve seen a boost gauge on a turbo car theyre not always at max boost. keep in mind, with our setup we likewise are going to need fuel system upgrades, fuel management, and a intercooler.
