    You cracked me up, Justin. Lol. I meant it for the daily driver, not all out track car.

    For turbo, the best is to go 1 exhaust for each bank. And if it's 1-2 divider, then a split Y (looks opposite to the letter Y) is the way to go.

    Those arms from Megan, right? They don't look like they have rubber in them, so they may make the ride bouncy.

    No questions are stupid. Only people's actions are stupid when they go against common sense. Lol. 1) You need that bracket for the drive belt to be routed since you remove the hydraulic fan pump. 2) You can use any hi-pressure braided hose. Anything that can handle more than 250 psi will be...

    94 SC400 wont rev past 700 RPMs

    I still don't see a big need to bypass the fuel pump ECU. If it's bad, then get a good used one. lol.

    Check the fuel pressure regulator, or change out with a good one. Do you get sparks at all ignition wires?

    single turbo size??? will a T3 work?

    I'd rather go with T4 to deal with less backpressure and overheating.
