i wanna do vtec in my 93 teg. i have a 50 shot right now and i want to run the nitrous on the vtec motor. i had my heart set on a c5 for a while, then someone told me they have an all aluminum bottom end (the sleeves are aluminum) but i'm not real sure on this source. I know the c1 would be good, but if the c5 has sleeves made of a stronger metal that'll withstand a 50 shot..... i'll get it. i want to run 14's without sprayin. If the gsr motor will do it....i'll get it. but i feel that the c5 will run 14's no problem.
