Well the 122 is on-and works-unfortunately to make it work I had to use all the 112 kit to adapt it so now that i have done that i do not have a 112 to sell that fits a cts-v.

I will get an installed pic tomorrow. to make it work i had to take the complete 112 kit-disassemble it down to the blower case and do the same with my 122 kit. in the end i had to redrill/oblong the holes and mount the 122 blower case on the 112 intake manifold. Then once the 122 was mounted on the 112 intake all the origional Cadillac 112 parts would fit on (except I upgraded to a 90 mm throttle body. I used cathedral port et performance heads in my new engine build so i could continue to use my cathedral port intake. I am glad i kept my 112 kit until i was ready to put it all back together or nothing would have worked for me. to do it again i would try to get a tvs1900 compressor assembly and put it on the old intake manifold-it looks like a direct swap from the 112. i should have taken some pics during the process but i was so frusturated with the little information I was getting from Members or the forums that i just went for it and made it work. With a 416 cubic inch motor I was not prepared to put my 112 back one and did not want to go n/a either. the car goes on the dyno on thursday and I am hoping to put down 650 ish to the ground without meth. If i can help anyone with the swap let me know-again i apoligize for not taking pics during the reassembly but i was frusturated and determined to make it work....

In for the pictures, are you 100% positive you ONLY used the 122 blower? how was the alignment on the back pulley and the jack shaft? what holes did you oblong?

I only used the blower case-the rear drive pulley/rear case housing is the same between both blowers. The only holes i had to oblong were the holes in the intake manifold wherte the blower case bolts onto the intake. Everything else was direct bolt on.

For anyone looking to do the same in the future, is it possible to just use F-body/GTO pulleys?
