91 camry 3SGTE swap questions

[milisd]

i doing a 3sgte swap into my 91 camry as soon as possible. im getting a 3rd gen motor out of a celica AWD.wireing harness and ECU all come with it. im putting the 3sgte in and leaving it stock cuz i still want it to be reliable because i put a lot of miles on and alot of highway miles at that. i think i have mostly everything figured out but i still have a few questions, correct me if im wrong but heres what i know im going to have some trouble with. im going to need to modify my rear engine mount cuz it will be alittle off, i will need to fabricate a down pipe to come off the turbo (unless a celica down pipe works, idk) the questions i have is...will my stock fuel pump from the 3sfe work with the 3sgte under stock boost? will the MAF sensor from the 3sfe work too? Will the "CARS WIRING HARNESS" plug directly into the 3sgte ECU? and will my tach, cooling guage and fuel guage still work? will i be able to hook up my cruise control (important cuz i do 400mile all highway driveing trips at least 2 times a month.). no to important, but does anyone know what kind of fuel mileage drops i can expect? the engine i got has the AWD transmission so can i just take the transfer case off and will it be just like a normal front wheel drive celica and work fine with drive shafts, or should i just leave my stock tranny in like i plan on doing? and please dont give me the speal about how im going to blow my stock tranny up, im not going to beat the shit out the car, just ocassionally and in a striaght line down the highway and stuff like that, im not going to be slamming gears down the strip. i think thats all i have for questions. Thanks in advance.
