oh, and as for your first question, the boost hoses should be the same actual hoses, but maybe different length. probably a different restrictor pill in the wastegate hose. not sure about that because i never tried to install my VF37. i also did away with the JDM factory boost control solenoid before it went in the car. but the radiator hoses should fit just fine. and all the electrical stuff plugs right up as long as you have the JDM engine harness. i will say that the power steering hose does not fit on the PS pump. there's an extra bend in the JDM one. so you'll have to use your USDM PS pump. and also, the AC compressor doesn't match up to the USDM AC lines. all easily remedied by just transferring over the three accessories over to your new motor.
