well the DE can probably reach the power levels of the E but for some reason some of the scca or whatever one of those smaller us racing series is, uses the ka24e.

all i know is that its some nasty compression, with a high rev limit and a wild, basically unstreetable cam. i have heard the idle is really high and it lopes and bogs unless its running on race gas and thats how its tuned. i could be wrong. i know matt has his little recipe he posts up every so often.

something along the lines of
9500 rev
high cr
3.73 or something gear
game over.

i wouldnt mind getting an 89 base (the lightweight) and stripping it, throwin in a cage, and getting an n/a sohc built with some itb's and a decent setup where i could still drive it on the street duh. i hear these race cars are pushing 300 n/a or something crazy like that. and they were using itb's too iirc. no idea but sounds crazy.

sr20de rwd wouldnt be hard either. and i know those things have some pretty wild n/a setups too.
