I was wondering how much horsepower we can get out of our motors without a turbo and cost wise.

suscribed to see where this goes i hope the price stays under 1500 for like 200hp...

but the 200 mark hasnt been broken yet..

Well, if you've stricken forced induction from the books in your budget, you're likely going to land around 200 ponies for about 2-3000 dollars. One of the most beneficial elements, the engine management will cost you about a thousand dollars for a good one. I don't know if anyone makes individual throttle bodies for the d-17 although I doubt it. I believe that your best bet is going to be to start replacing internals such as cams, cam gears, pulleys. It's going to cost a considerable amount of money, but you could also yank the engine, bore out the block to increase displacement. ALthough I don't know much about that. I think it would cost more then it's worth it in my opinion. But it's up to you. Remember, I don't know the actual ratio of weight to power, I read in import tuner a while back that if you rip out 14 pounds or something like that from your car it's like gaining one horse power. I think you would have to gut most of the unnecessary weight as well as beef up the motor.

Its gonna cost more than building a boost motor. Mostly because you don't have any other choice but to do major head work. I'm not talking about a hog job, you gotta have someone who really knows how to build a SOHC head work it over. Its gonna cost you some serious money. Boost on the other hand, could basically care less, its getting shoved down a hole, and its gonna fill the cylinders. Port jobs on turbo motors are optional, and not really necessary.
The bottom end build will be more or less the same, you'll have to rev the **** out of it, so I'd be sleeving it and packing it full of forged crap, but use high comp pistons instead of low comp (yes, wiseco makes high comps now).
Before I get into the nickel and diming, Its gonna run be about $3500 IN PARTS to build my turbo motor. Thats rods, pistons, rings, cam, springs, retainers, new sensors, gaskets and pumps, and the sleeve job. Not counting the refinish work on the head and also not counting new engine management.
I bet you can add another 1-2K for portwork done right. So for $5-6K is it worth an all motor SOHC? Probably not considering you can drop in a K for about that much and get the 200HP in a weekend. Getting 200 without a bottle or boost on a single slammer AND keeping it together is pretty hard to do. Most guys with race built SOHCs are making 145-160 at the wheels, and you can bank on those motors being built pretty well. The heads just dont open up to flow the volume of air you need to make gobs of power.

Well, I believe regardless of your horsepower goals, you need to set a budget. That's how production companies make things happen. Get what you can with what you have. That's what I'm doing. It's always a good idea to know what you are going to get into before you do.

you can modify a d16y8 im onto the d17 and then youll be able to use a b-series throttle body.
