well, I can't use the hiboost cause I have a full length rad and full length condensor. I know ION is impossible to get and MAM's is too expensive and I don't know if t he perrin will fit because of the same reason. It would help if I wasn't eliminating half of the kits out there.
I think the BEGI kit costs around 600 if i'm not mistaken, and I believe it allows for a bigger rad. I'm not 100% sure right now. You should look into it.
