i also ave a CA18DET thats fully built, and its almost done, should be around 400-500whp on pump gas.

but i have a KA as a daily, which will eventually be my drift car.

i wanna know what all you gys recomend for a little more power, i know i need to do the 248/248 cams, but other things than that,

current mods are.

NO air filter(dont flame)stock exhausts with test pipe, and no axle-back.timing is up.compression is between 190-200i also have a 6puck stage 3 in it, with a welded diff.AIV/EGR is blocked off, but a bit "ghetto" but it works.

what are some other little things i could do? fyi, its the strongest KA ive ever had, and the strongest ka that anyone around my area has seen.

ive been thinking of boost, but would rather have it NA. just to see what i can do..

what i was gonna do is 370cc injectors, n60 maf, wideband o2 and a tunr from emance. From what I read it should give you a better powerband and about 10+ whp

190-200 is great compression- definitely keep that NA.I'm guessing you want to keep this cheap- ebay header might help things out.If you're willing to shell out a bit more, I'd recommend some aftermarket cams (Brian Crower, PDM) and ecu tuning of some sort.I loved my KA after upgrading to a lightweight flywheel, but you might want to keep the stock for drifting to maintain that inertia (not sure- drifting not in my repertoire).
