Any Way To Get To 300hp

[BLKWLF]

I already asked once how much hp could i get from an NA build Prelude Type S engine. But now i just wanna know is there any way i could get to 300hp or at least close to that without replacing everything? And also what could be done to accell to 300nm?

where there's money there's a way so yes you can get close to that. but how do you gain more hp? tune and build. fine tuning your car wont give you the extra hp like you want. so replacing stuff with betters parts is what your gunna have to do. these engines were really made to race and have have some huge output. they were made for daily drivers who occasionally get spirited sometimes when they drive. so no you cant do it without replacing everything.
good luck in your car man look forward to see what direction you take it.

X2 first question is how much money do you have?
Yes you can get 300hp - You could even get 500hp But how much money are you willing to shell out?

aahhh, no

you see these motors have like 220 stock hp. and a nice tune will probably give you 230. tops.

you have to replace....

block: pistons, rods, crank (stroke to 2.4l), main bearings
head: 1mm over forged valves, springs, retainers, cams, cam gear, port and polish job.
bolt ons: skunk2 or ITB intake manifold, bored throttle body, custom header back exhaust system, ignition setup, lightweight pulleys, lightweight crank pulley.
trans: at least a stage 1 clutch.

that should be able to get your 300hp or more with a fine tune.


ATTENTION!!! When running higher compression pistions or stroked motors need to run 93 or higher.

Money is no issue.

Ps. Not rich just a well paid factory job

research my friend...the force is with you...

[The G-Man]

Not unless boost is introduced.

[foamypirate]

Not effectively and reliably unless boost is introduced.

Fixed.

Whats the definition of not replacing anything makes it sound like leaving it stock or just bolt ons... IF we are talking crank hp it might be possible but doubt it. WHP definitely a big NO. As I have said before guessing power figures is pointless. The h22a has power potential being that you started with a top of the line one. But it will be meaningless IMO if you dont have a baseline to see where you stand rigiht now. After that you can gauge on what you need to do. All motor wise it is possible to push an h22 to 300hp. It just takes a lot of money and research. Last I recall 2point6 was pushing close to 300 before his engine blew.

dark accord built a h22 with itbs and it was making close to 300whp.

Dark_Accord turned 18 last month, doesn't even have a CB7, and isn't exactly an automotive genius (don't get me wrong, I like the guy...)

You're thinking of 2point6.




300hp, wheel or crank, will be difficult to do NA without some major work to the engine. A 220hp engine makes about 180hp to the wheels. Cams, a GOOD header (upwards of $1200 US), a good exhaust, a larger throttle body, and a good tune will probably get you a whopping 40whp more... if you're lucky. Any cam that will give decent power would require an upgraded valvetrain, which would require the head to come off... so either you take that much apart, or get a mild "stage 1" cam... which, if you're starting with the Type S, won't give you much of a gain, if any. If you do remove the head for a valvetrain upgrade, it'd be beneficial to do some port and polish work, as well as a 3 or 5 angle valve job. Then, once you have a nicely flowing head and wild cams, you'll need to rev higher than the stock redline to make the most of it... Do that on a stock bottom end, and you could find yourself with stretched rod bolts or spun bearings. Even a Type S engine is fairly old to be revved higher than intended too often! To prevent this, you'd want to upgrade the internals... At least new rods and pistons (aftermarket rods don't usually work with stock pistons). If you're going to do all that, you'd be limited in your piston choices because of the FRM sleeves in the block... so resleeving would be a smart thing to do. If you resleeve, you might as well increase the bore to up the displacement! If you're doing that, you might as well use the F22 crank to add even more displacement (As you can see, I'm pretty much re-creating 2point6's engine at this point...)

After simple bolt-ons, the heavy stuff is all tightly connected. Do one part, you should keep going with the rest.




Turbo would be a great option to get to 300hp. Especially if you're talking crank hp, as 300 at the crank is done VERY easily with stock internals using a turbo... as long as the turbo is properly sized, and the ECU is tuned properly.

However, the 11.0:1 compression ratio in the Type S is NOT a good choice for turbo... As I said before, if you want to go the stock-internal turbo route, sticking to the F22A would honestly be the best option.



Nitrous, of course, is another option. As with turbo, the high compression of the Type S would make it risky to go above a 50 shot... but it's something to consider.

No Mike, im talking about dark accord from back in the day, who is 22 and owned a accord and now owns a S2K.

His MR says he was only making 240-50. He expected 280 after some head work. But then it looks like he parted it all out before doing the head

i dont see his hp in his MR. im pretty sure he was doing more than 250hp to the wheels. he had alot of work done, like those itbs he installed. yea sucks he just sold the car.

[deevergote]

Ah, ok. I don't even remember seeing him around! I wouldn't have changed CAH's name to dark_accord if I had known!
