Hi, do you guys know any company out there that make a rotrex kit for our beloved B series engine?

No company has made a kit, but someone over in Europe has done it.

We have been looking for a kit for a while I have a customer that wants one on his B20Vtec powered DA integra.

kraftwerks is coming out with a b series race kit but don't know when. I emailed them a while back about it but they never returned my email.

Uncle Dave

I will call Brian in the morning then and find out directly from Kraftwerks,last time I asked they said they where not going to do a kit.

C'mon kraftwerks, there are still a lot of us B series out here that are hungry for ROTREX.

Look up ATI pro charger! they sell a carb legal b series centrifugal supercharger, check out my build! 300+hp @6psi retuning at 12psi shooting for 375+hp. Did i mention people have twin charged there b series with this unit and a turbo setup together lol.

retuning at 12psi shooting for 375+hp.
Nice setup. Got chance to retune the new setup yet? Can this s/c push over 400 whp on a build engine?

wunfstgsr

not yet! sometime mid sep. Im ordering a 12psi pulley soon so it should get retuned very soon stay tuned on my build thread. Yes this can push some big numbers on a built motor, churches said they only had one other pro charger they tuned and it was on a sleaved B series and made a lil over 415 hp with 14 psi, with a custom header and cams and a custom intake manifold you could make a beast, im debating on twin charging it with a turbo in the future or go all custom with the header cams and a more race inspired intake manifold and 2.0 l w/sleaves and boost 15-20psi and see what it makes. by this time it will be a full out race car and i wont get away with daily driving it like im now. and even now its heavilly modified but i have it somewhat street legal with the carb stickers i have on the mods such as the DC carb stamp i welded on my SK2 alpha tri y header to throw off cops.
