As far as the "top swap" goes I'd just grab it all from a junkyard. Would be a lot cheaper. Heck, they even show up on here now and then. If you need to tune it then get an HP Tuner or the like. Then throw in some headers and call it done.

I was thinking about wrenching as much as I can off of an L32 and have ZZP reflash me to the GTP image (only $40 for reflash since they did my original tune, cheaper than $500 for HPTuners lol.)


Do you think I should just not oil the K&N filter then? I don't really get what the oil does if I clean it regularly unless it makes it aqua-phobic or something.
