In spring i am going to be building my prelude to have 240-250 whp. Im hopefully going to do this with out a turbo setup. I dont want to have to resleeve my block and buy a turbo kit. I was hoping someone could explain to me if these mods would bring my prelude to these numbers or a little above.

Skunk2 Intake manifold
Skunk2 Throttle Body
Skunk2 Cams
Skunk2 Valves
Skunk2 Valve springs
SKunk2 Retainers
Skunk2 Cam gears
AEM tru pulley kit
Skunk2 N1 Exhaust
Apexi VAFC controller
RMF headers
AEM Cold air intake
Koyo Civic Racing Rad
Exedy Stage 2 clutch
Fidanza Flywheel
Forbiden short shifter


Any help would be truly appreciated

thanks

Well, you definately don't need 2 sets of pulleys...let alone 1 set of AEM pulleys. The only way to make a difference from pulleys is a lightweight underdrive crank pulley (AEM doesn't make a crank pulley) and to loose PS.

Also only need one header.

 

i thought that AEM had2 diffent pulleys kits. i thought that the tru pulley kit was just the underdrive pulley. My bad i guess and i only have one header on there. the RMF. What would you suggest i get for pulley's? Also how is driving without PS i have never acutally driven without it?

 

 

sounds like a good set up man. And I think the guy above me was referring to "RMF headers"... 4cyl=1 header And for pullies check out Unorthodox Racing , I just ordered mine today

Yeah, get an Unorthodox crank pulley. Driving without PS is no problem after you get used to it...with the exception of speeds under 5 mph.

 

ohhhhh sorry, i see. Yah i know its just a single set of headers. Ive heard the RMF headers can give a good 10-15whp but they cost a pretty penny. I was think unorthodox pulleys but i have heard they damage your car the most out of all the pulleys. Let me know when you got yours installed on how they feel.

 

Generally speaking, from what I gather, people usually do quite a bit more to get that sort of NA power. To say the least, a short shifter wont get you there.

 

yah i know a short shifter the clutch and the flywheel wont do anything but free up power that was lost. but it will help put power that would be lost to the wheels. Ive seen alot of people put way to much money and buy way to many parts that are not needed to get 250whp. Tuning is a huge part and i have seen people do less and show me dyno sheets with an h22a and get around 220-230 whp. I just read in a different forum on cams that skunk2 camshafts and crower were giving a boost of a good 15whp.

 

If you're lucky, on a good tune, you might get 230 whp.

Without cams, there's no way in hell you're getting to 250 on that without playing with fuel, ignition, compression, etc.

Don't post stuff like that unless you can back it up. If anything, UR makes the highest quality crank pulley next to Fluidampr. Anyway, let's not make another crank pulley debate thread. If you spend all that money building up your head, it would be stupid not to upgrade the cams. Forget the AEM pulleys all together and throw that into the cam fund. And you should be able to find a better deal then $750, unless you're buying all this directly from Skunk2

 

thanks, im not hating on unorthodox and i wont make stupid posts like that anymore. I do agree that its pretty stupid to do all the headwork and leave the cams out. I was planning on buying all the stuff directly from skunk2 except the exhaust. Know where i can get better deals?

 

Yea, Ill let you know once I get them installed early next week. I know I wont be able to tell any difference because Im a ***** and only got the atl. and sp.

 

i dont know about 250 on only a VAFC either.

 

Honestly, I don't even see 230whp with that setup. You would definately need camshafts, and you might as well if you're going through the trouble of cracking the head open. I really don't see 240whp without cracking the block open either, that or nitrous.. of course there are always exceptions.

As said here, and everywhere else.. tuning is key, and i'm sure most peoples idea of a 'good tune' involves a bit more then a VAFC; I would go with something along the lines of hondata, chrome, or neptune.. depending on the experiences of your tuner.

IMO, to reach your goal of 240+whp you'd need something along the lines of; jun cams, ported head, and some 12:1 compression pistons.. thought that may be overkill....

nah :D

 

Here's my revised list, keep everything in bold;

Skunk2 Intake manifold
Skunk2 Throttle Body
Skunk2 Valves
Skunk2 Valve springs
SKunk2 Retainers
Skunk2 Cam gears
AEM tru pulley kit
Skunk2 N1 Exhaust (I recommend something else - 2.5" dia a must)
Apexi VAFC controller
RMF headers<U></U>
AEM Cold air intake
Koyo Civic Racing Rad
Exedy Stage 2 clutch
Fidanza Flywheel
Forbiden short shifter
JUN Stage 2 or 3 cams
Chipped P28 with Crome Pro

That will put you at 250 whp no problem.. someone has a setup close to that and is pushing 252.

 

^ Jun only has one stage, yo.

 

i was thinking something like hondata s200 if i decide against the apexi vafc. I honestly think i will be able to make that kind of power and i know that the tuner that tunes my car will be able to crank out that power if everything works out. I guess the part keeping me from acutally going through with buying all these parts are the actual power an h22a acutally puts down with these mods. I have heard people say they got 10whp just off the RMF headers, 8whp from the apexi vafc and both have shown dyno sheets so its believable. Exhaust giving 7whp with some of the listed mods, intakes giving 3whp with some of the mods listed, and i know that combined with all the other parts i have listed im sure i will be able to crank out more. There is a thread about the camshafts from skunk2 producing 19whp with just cams and type s pistons. Maybe 250whp is a bit to high but is 230-235 more realistic?

 

if?

you will decide against a vafc if you plan on having fun with the car, meaning it not breaking down all the time, and gettting the goals you want. I dont think you understand what all is involved with getting that kinda power, not to mention maintaining it.

you cant just throw all those parts in and expect it to run top of the line.

 

no way will you get near those numbers without touching the bottom end, not to mention "radical" cams also.

Research ownz j00.

 

ya, they're all the same cams--stage 3, but just different spring rates for the valvesprings

 

hahaha, 250whp with an NA motor with a VAFC.... even 230whp would really be pushing it....but I suppose if you could figure out how much more fuel you were using in the higher rpm, you could replace your injectors with larger ones so that your VAFC hack would not have to make very much change to your fuel maps in that region where you will be making most of your power, but your car will never run half as well or be near as fast without standalone

 

Sorry for not know as much as you guys obvisously do, i was simply asking for some feedback not to get laughed at. Obviously a vafc is not as good as a standalone , which is why i am asking for your feedbacks . what numbers would those who claim those mods wont make that power what is your prediction for numbers? Someone posted their prelude a little while ago with a custom intake manifold and rmf headers and his prelude was 230whp with even less mods then the listed ones. I seriously dont appreciate being laughed at. For that matter is the Skunk2 intake mani almost the same as stock and would it be better to get a custom intake mani?

 

Based on previous dyno's I've seen, I doubt you will crack 190whp. Stock block/compression seems to make the cams less effective. I've never seen a good na motor put up good power using just a vafc. Just remember that the cams themselves don't really increase power that much. Its everything else that makes them give good gains. Additionally, you need a manual tensioner conversion. Do some more searching/research in this forum and all motor forum. Get some feedback from local shops and tuners too, never hurts. You seem like you're just starting out in the game, try to learn as much as you can before you actually buy anything.
