i wouldn't put a turbo on the stock motor. i have one myself, and was asking the same question. ur only going to be able to boost 4-5 pounds. thats only 40-50 horsepower, not much when u only have 115 stock. i have NoS on mine. its a 50 shot pill, set up as a fogger. which is equivelant to a 30 shot. thats only 30 horsepower. it still gets up for sohc non-vtec though. even without NoS. what im planning on doin with mine is fully building my motor, run low compression, and slap a t66 turbo on it. but i want to have a more powerful motor, and also hear v-tec again. so i think im just goin to swap the k20a2 into my car. after i save up for awhile, and get lucky enough to find a wrecked rsx at a junkyard. thought i might be able to help u out with that. goodluck
