03 gsxr 750 motor in an 83 gs750E frame

[Guest]

hello guys. i had been a member on here a few years back and ended up selling my gs. well after it had been in a really bad flood and left sitting for a few years it ended up with me again. as of right now its just a frame and a title for me. i have the opportunity to get an 03 gsxr 750 with a salvage title and i would like to put the 03 motor in the 83. i know that the frame design is completely different but im not really all that worried about that. im thinking i will have to ditch the airbox and find a fuel tank that i can weld the pump mount into. my main question is has anyone on here done a motor swap like this (twin spar frame motor in a cradle style frame) and down draft fuel injected setup with a frame and fuel tank that was designed for a regular set of carbs and no pump in the tank? any and all input is welcome in regards to this build.
a bit of background on me i guess. im not new to bike or motor swaps. my last build wasnt as complicated as this but wasnt that far off.

Welcome back. That would be a powerful swap. If you ran a custom intake setup to account for the angle of thise throttle bodies, you should clear the gas tank. The other issue is how large is the radiator for that motor. You may run into clearance issues. Aesthetically, the rad is going to look out of place, imho. A member did a watercooled swap, but I can't find the thread.ill see if I can find it

as of right now im almost tempted to just cut the head tube off, make a jig, and make a whole new frame.

or just run the lowest profile pod filters i can and tune the motor with a power commander to compensate for the volume of air it would be getting. not really worried about power as my other bike has about 180 at the rear wheel and weighs about 375 pounds dry. give or take. built 08 gsxr 1000 motor in a 98 gsxr 750 frame. a few other little things done here or there
