i am planning to start building up my engine soon. for now i just have i/h/e. ill have aem tru-power pulley kit installed soon and new spark plugs. i was planning on getting an intake manifold from dh-racing, and having them port my head and throttle body. i was also planning on buying their stage 1 valvetrain kit which includes camshaft/valve springs/retainers. and ill also get the dh-racing crank pulley(with ac/ps). what kinds of gains can i expect from stock? later on i plan on boosting, but i want to build the engine first so dont say "its pointless you should just boost" .

well i think it would be pointless to get your head ported right now especially if you are going to "boost" in the future. wait until you get the turbo, then have it ported for a forced induction application instead of n/a. you will get better gains. hp gains? but you can build the head with new components without losing any power. if you get pnp for FI before getting the turbo then you will lose all kinds off power. and make sure the camshaft is compatible with turbo ie. duration and overlap.

well then, learn something new every day. i didnt know there was a way to port for n/a and for fi, i thought it was all the same lol. thanks for the info. what if i went all out n/a? what kind of gains would i see from the stuff i listed above?

Turbo it

in reply to the above post:

i did not make this thread so ppl would tell me what to do, i do plan on turboing it but after i build the engine so itll be able to withstand massive amounts of boost. ill prolly just get another engine and build that so i dont have to be carless for a while. but this doesnt mean i dont want to have any fun till that time. thats why i want to do some headwork on the engine right now. it seems that the only problem with our civics is that not enough air can get through to the cylinders. porting seems to help a lot, as does getting a new intake manifold. getting cai and exhaust and headers wont give us gains because once the extra air gets past the intake, its just stopped dead by the crappy intake manifold. if we get enough air flow going who knows whats possible. look at what turbos give, its the same as opening up air flow to the engine. thats what im planning on doing later, but for now lets see if i can open up more flow without going with FI .

edit:
also, lets say i get somewhere between 175-200hp, would i have to upgrade my transmission/torque converter and get a transmission cooler? ive heard the 7th gen auto tranny has overheating problems? oh, and in case u havent figured it out yet i have an automatic .

I heard when you boost at above7 that you do need a trans oil cooler.
Dh-racing pnp head alone will give you 25+ HP . Also adding a fuel pressure regulator would be good to get the most out of the pnp but its not neccesarry. Torque converter im not sure if its neccesary so i wont comment. Hope that helps

What engine do you have?

If you have a VTEC then go Turbo or NA
Auto is not really good with Turbo setup. Turbo will put to much load on the transmission

If you have a Non-VTEC go Turbo
But don’t put to much boost it will take out your transmission. At 8psi you will get an estimated 180+hp.

If you are putting that much hp on your engine you will have to get an external tyranny cooler. Specially you have auto. If you don’t have a torque converter you will loose all that hp that you gained.
For my self I will get a
1. HD custom intake manifold and throttle body
2. Valve train kit and stainless steel valves
3. Head shave to get more compression 10.1.1 compression

also if your planing on boosting, save your money, and don't get intake, headers and exhaust.....

whats the point of "shaving" your head if you going to stick with the stock compression pistons. And also, the valve train kit is nice, no doubt, but I wouldn't recommend regrinding your cams. It weakens them, and although it provides power, you should really look into billet cams. (Gonna have to get them custom made)

There is no reason why u can't port and polish your head Turbp style before actually owning the turbo. You wont see braely any gains at all from it but atleast you have the ability to procide more boost.

If your going to "build your block" start from the inside out. Stronger connceting rods, pistons, then work into the head work, along with all the valve train mods, and to top it off with the intake mani and tb. That's the mistake most people make.

Plain and simple don't ever lead to one direction because of something in your setup, it should just make you want it that much more if you have to do a big mod to achieve the power you want. Auto's on the D17 I have heard nothing but bad things about with big power, tranny's just exploding, so I would suggest doing this

Our Intake Manifold Combo
Ported Head
Crank Pulley
VAFC or SAFC
Maybe High Or Low Compression Pistons (Rods For Turbo)

Then deciding with your setup what way you want to go. This will tell you if you like all motor power or if you want the power of boost.

All and all I say build your auto tranny if you want to keep it. You would need a tranny cooler, upgrading gearing, and a much better torque converter. My buddy is doing one, but let me tell you he has spent a mint on it, so I would much rather tell you to spend the 1000-1500 to swap in an auto tranny. He is spending more then that on a built auto tranny. Either way I would be glad to help you with any questions. Someone told me people were saying you will lose HP on NA setups with our ported head, just have to say that is a joke.

Also the valvetrain kis IS NOT necessary on SOHC Motors, but if you want to feel more efficient or run it to 9500 RPM's like me :-) then go for it. But on boosted setups you would not even need to think about it
