Well first of all thanks for the good comment's, The mod is actually really simple, will try to post the proceedure soon. As for the turbine side, that has been a real disapointment. The work that went into the compressor housing was simple compared to the work of the larger turbine wheel. The power increases were not worth the trouble, at least at the 650cc size. I would like to see what the larger compressor/turbine size would produce when I get around to putting the 750 crank and pistons in the 650 turbo cases. As for the balancing there was no problem with getting the upgraded compressor to balance with the stock turbine wheel, likewise with the larger turbine. This project of putting the larger turbo parts to the seca is just something for me to play with, and not to try to build BIG horsepower, The seca is just to unstable to try and do that to. No Fun intended to my fellow seca owners, but if your looking for a fast turbo bike, go find a 750 Kawi, they got more power stock than the seca modified does. I know I have both.

We'll just to be truthfull, I made that swingarm to accept the larger rear wheel and added 4 inches to it to keep the front down, the bracing was actually a after thought, and didn't help for s*@t, just looked nice . But show me a seca that needs a longer swingarm to keep the front down, and I'd be impressed! As for the 900 turbo seca, find me a xj900 motor and I'll try it, been looking for a while to find a engine. Don't think the frame would like it to much,not to mention that the front forks and brakes on both 82 & 83 model's are we'll ,um , ok they suck really bad.Just my two cent's.
