Hey i have a 2000 Ex with the d16y8. I have searched and haven't found my answers... I am looking for a little more power. my goal is 200 horse power at the wheels and as much torque as possible. I am NOT going to boost so don't mention in please.. my question is what swap (or other things) will get me that much power (or close) and still get decent gas mileage? If you do not have anything useful to say please don't bother posting. thanks.
Gas Mileage + power?

a built ls/vtec will make 200, but, your talking about a lot of money. You can make 200 on your y8 for fairly cheap if you turbo it 
^^^^ i agree a built motor will cost a lot but not as much if you turbo it
alright... okay maybe i'm shooting a little high. i just want more than my stock 127hp = about 103 at the wheels.. I just want more power and keep my gas mileage. I would like to keep in normally aspirated.
By that you mean naturally-aspirated right?? I would go with an engine swap if you dont wanna turbo and sorry to burst your bubble but N/A is not cheap
well you can swap in any stock b series vtec motor and make a bit more power while not sacrificing to many mpg's, but a bone stock B swap won't get any where near 200 whp unfortunately. I know you said you're not interested in boost, but i make over 200 whp on my stock y8 while still getting 29-32 mpg. I dunno what your budget is, but perhaps an ITR swap or k20 swap would best fit your needs.
It's usually one or the other. Keep in mind that the more power you make the more air and fuel your gonna need to feed the beast.
well i might have over 5k to drop into my civic if this thing goes through but if not i have under 3 thousand. yes i mean naturally aspirated... Does anyone have info on the differences of the b series? I know it is probably my best bet to go with a B.
The differences between the B16 and the B18 is B2.
Lol one has more displacement. Stronger engine= more applicable power.
ITR would be the B18c5 right? but that is quite a bit more expensive right? and i hear that parts are harder to get. But i'm kind of leaning towards the gsr... but that is the b18c1 right? and with a stock gsr i'll be about 130-150 whp?
i would go with a b20 vtec and a tune...
I hear both good and bad about the b20. what would i get horsepower and torque with a b20? and what are the pros and cons of the b20 vs gsr?
USDM is B18c5 it's a little more expensive for a good mileage swap your looking 2500-3000$ I'm not sure of the differences between the c5 and c1. And if I'm not mistanken the stock hp is roughly 190 hp
okay then i'll try to find the differences between the c1 and c5

Is this telling me that the c1 will give me more low end power because vtec comes in at 4400, but the c5 will get me more high end?
alright... well first thing' first. More power will always require more fuel.
i believe d16y8 has about 130hp, and your goal is 200 without boost. Your going to have to rebuild the motor it internally, tune your ignition system, intake/exhaust system, and you'll also have to do some tuning to the fuel system so that everything works harmonically. you will also benefit from ecu tuning.
