Yeah a DIY twin turbo kit

. I couldn't imagine how long the write up alone would take. Pictures and stuff of the process would be cool though.

will do for sure. it will probably take a month or so to do. try and built it in june and yearly july. as soon as the snow melt and sled go by by im getting the suncoast in. as soon as the banks goes im getting EFI LIVE. then need guages, airdog, tierod, pitman support, and then the turbo and start making the pipe. only thing im worried about it oil hook up and the wastegates.

haha, wont be to bad. you should see some of the suspension writups i do on sleds and talking about valving. got 20 pages on info going back and forth on a mod to a polaris prox suspension and tuning for it. i can make it worth everyone's time. now does anyone have a use s475 or s478 turbo around? dont know which to go with, the s475 is only 600 buck, s478 is 900. i can get to a/r's 1.10 or 1.32

what do you guys thing here for a large turbo. im between 2 turbos. the B2 s400 is 650, 74.5 compressor wheel 1.32 a/r. the s475 is 600 bucks and has a 75mm compressor wheel i can get 1.10a/r or 1.32a/r. the s478 is 880 with a 78mm compressor wheel and 1.10a/r or 1.32a/r. any guys that know a little more aobut turbos want to give me a little advice. also wastegate, 40mm or 50mm? i think i can get away with a 40mm

thats what she said, hahah. well i just dont know if its worth going to a s478. i dont know if i can make it worth while. if i had a bd or htt as a smaller turbo them ya, then again im thinking of upgrading to on in the future so many do the bigger turbo them?

with the stock turbo i would prob say stay with the S400 or S475 or else your offset between the 2 will be hard to work with when setting it all up.
