the ka compression ratio is also higher. i say he can do 250whp safely on the 370cc injectors. were it me, id try it, and if the a/f wasnt at a safe level then id upgrade. its not my car though and the the deatschwerks 440s are cheap enough that you'll only spend an extra $100 (if that) over the cost of a set of 370s.
250whp is plenty. with the massagin of done on my 25 its probably close to 240-250whp and my 14 will slide just fine. where people get into trouble is they ask more of their ka than they should. if you want to get 300whp then your lookin at a head gasket and since you've replaced the head gasket you might as well do the pistons cause they'll go soon too. its becomes a vicious cycle when the car was supposed to be cheap fun. its like gettin a stripper pregnant.
