95 ex h22 swap

[jazer80]

i messed up my stock engine, and am gonna swap to an h22a. how much of a gain should i expect on my times 0-60 and 1/4? oh what components that are on my stock (f20 i think) engine (headers intake exhaust ignition spark plugs) will fit onto the new one?

You can get entire H22A swaps for about $2300, including starter, pump, etc, etc, etc. Why bother with finding out what fits? Just get it all with the engine.

dude im talking about all the aftermarket parts that i listed

What aftermarket items did you list? I don't see any aftermarket items in your post. You have a stock engine in your 95 Accord EX (which is the F22B1 VTec). You want to use the current header (don't think that'll work going from SOHC to DOHC), intake, exhaust, ignition, etc.

If your header, intake, exhaust, ignition, etc is AFTERMARKET -- SAY SO !!!!!! We can't read minds. All I see is the word STOCK in your post.

Edit your post, and try this again.

I see the parts he listed........


anyway.......exhaust and spark plugs will work for sure. Ignition i would say most likely work. Header is almost definatly a no and intake i would say 50/50. Please keep in mind i have never done this swap so im not positive.

I have a 95 EX and I just finished doing a GReddy header and cat back on mine and the paperwork that came with the header says it fits
1994-97 Acura Integra GSR 1.8L DOHC VTEC
1994-97 Honda accord EX 2.2L SOHC VTEC
1992-96 Honda Prelude Si 2.2L DOHC VTEC

so the bolt pattern SHOULD fit the H23a. I don't know if it is the same for the H22

[jazer80]

i thought the prelude si was the h22a and the h23a was the non vtec one..but i'm not too sure. anyone know?

Exhaust is about the only thing that will work because that is somethin that is angled to fit your Accords undercarriage. Your spark plugs are gapped slightly different than the ones that are for the H22. Your ignition? The H22 comes with a distrubitor and chances are your Accord one won't work on the H22. If your talking MSD or another aftermarket one, yes it will will work on either application. Intake? Ideally you should use the one for the Prelude as the Diameter is slightly larger than the one for the Accord and that just really depends on the manufacturer. The Accord intake will route in your engine compartment better than the Prelude one, as it has a stronger angle leaving the throttle body. The header from your Accord will NOT work on the the H22.

Something you have to keep in mind when doing the H22 swap is that you need to start looking at parts for that year of Prelude when ordering them for that engine. Secondly don't think for a moment that just cause some of your old Accord engine parts will work, that you should use them. The H22 is built to take more air in and push more out, by using the Accord parts you can and will be constricting the H22's capabilities. There is alot more to a DOHC than a SOHC.

How much should you gain by swapping in the H22? Well that will depend on if your still trying to use Accord parts or not. Also depends on how well you can really drive your car. Ideally a good straight swap will take you from 17 second 1/4's to atleast 15's. When you start building up your H22 then you will continually lessen the time. Its a long road brotha, trust me! Be patient and be wise!

The Prelude Si is non-VTEC = H23

what would the differences in performance be between doing a swap and getting a turbo kit on my current engine? I'd be able to keep all my aftermarket components if i got a turbo. it turns out my engine wasn't as bad as i thought it was -it was hydrolocked and i thought i lost a few mpg but i really hadn't. would i be able to install a kit myself? does anyone know good sites for turbos, i was looking online for kits for f22's but couldn't really find any

Call up www.jacksonracing.com and ask them if they ever figured out the supercharger for the Accord. Damn you Honda for making the intake so tight!

40% more power at all RPMs!!

[jazer80]

i don't think i want a supercharger. will getting a turbo kit (a moderate kit - nothing more than 2500$) on my f22 be more power than switching to an h22?

I have never been in an H22 Accord, nor a turbo Accord... but here are some things I have read from other people that you should consider.

If you go with a turbo on the F22, that's it. Aside from changing some of the internals of the engine, you are maxed with your speed. Sure, you could make the car lighter by ripping out the back seat, etc, but that's that. If you put that same money into an H22, you are just beginning. Then imagine upgrading the H22's internals, putting a turbo on an H22.

The gearing in the Accord is so quick, I just don't see how a turbo would help until you are already in 3rd. If your Accord was anything like mine (why wouldn't it be), you already have a car that goes 0-60 in 8 seconds in 2nd gear. At redline, you should be going about 35 at your first shift, and throwing it into 2nd, you only have about 4.5 seconds before your next shift. I haven't been in a car with a turbo for some time, but I remember that it didn't kick in until 4500 (for a Shelby) or so. If you put a turbo on an F22 Accord where it kicks in at 4500 rpm, you will only be using it for 22-32 mph, 45-60 mph, 70-95, etc.

If you put an H22 in, you will have the extra power and torque almost everywhere. I have heard that H22 Accords can compete with V6 Mustangs, so you are looking at 0-60 times in the 6's. Not only do you have the extra HP in a broader RPM range, but you have more torque, which means your car will accelerate faster with other people in the car, with a full tank, with stuff in the trunk, with a bike rack on the roof, with a trailer in tow.

I assume that today's turbos still have to warm up and cool down like they used to. I don't know about you, but I never enjoyed sitting in the car for a few minutes after I got to my destination letting the turbo cool down.

One more thing to think about. The life of an H22 is MUCH, MUCH longer than the life of a turbo. By the time you are rebuilding or replacing your turbo for your F22, you could be adding your first turbo on an H22 -- for the same money.

Now, I say all this with little knowledge of today's turbos. I haven't messed with turbo for 8 years. Maybe turbos these days don't need to cool down. Maybe today's turbos last longer than 10000 miles. I just don't know.

Virtually the same stuff that I said that wouldnt work with the H22 will not work with your turbo either. Header - Gone! Injectors- you need bigger ones, spark plugs- your going to want to upgrade to something thats going to last, and with that said an upgrade to your ignition, i.e. aftermarket.

Ideally you need to decide what you want versus what you are willing to sacrifice.. I'm sure most can agree with me when I say this, but we all generally want the next best thing and when we half-ass it just to have it, then comes a day when we wished we had waited and done it right, because now we are redoing what we half-asses..

If you turbo your F22; thats it.. Now when you wnat more you can't have it, now you've invested thousands of dollars to find out you still want more, and now you either live with it, or you dump that money down the drain, and start over. Do it right the first time!!!

Peace!

more or less in the end you're going to wind up selling off your old parts and getting some new ones, it'll be more money to spend, but you'll get the best gains and such from doing this.
