i was going to do similar conversion but i decided to go the 18rg.. i have read that the ct26 goes well on the 22re or a t03.. my opinion i agree with those 2 options you can get a ct26 for nothing i have seen them for 300 bux in good cond aparently.. for a good t03 you wil be looking at round 500-1500 depending on the condition.. the t03 flows alot better then ct26 being garret.. well thats my opinion anyway.
