Need new motor. Which one to get?

Hey guys,

As you can tell I'm pretty new to all of this. I found out my motors a goner. I have a 1998 Base, so I have a h22a? not a h22a4? Well I'm on the market of buying a used motor. What type of motor would you recommend? I didn't know there were so many different options... I looked into it an the f20b seems pretty popular. I found them for around $700 while h22a's go for around $1200. Since its only a 2.0 im guessing it would be more fuel efficient but with less torque? But I don't know too much about what alterations that need to be done. I know my mechanic does engine swaps on hondas all the time so would it be okay to just drop off a motor and tell him to do it?

haha sorry for so many questions. Could someone tell me all the different types of engine swaps I could do with the pros and cons of each motor? That would be awesome.

Thanks again for your opinions forum!

ALSO, if anyone out there is selling a motor please PM me I would love to buy it off of you! I'm a student who can't even afford to pay his tuition.

H22A - Japanese H22, I think something like 5-10 more bhp then your current motor. you need to convert your vehicle to convert your vehicle from OBD2A to OBD1 with a jumper harness that you can find here Wire Harness

H22a1 - Came in 4th gen USDM 93-96 Si-Vtec preludes. if it came out of a 93-95 you need to convert your vehicle to OBD1 again

h23a(1)- Came out of 4th gen 92-96 preludes SI's. need to convert to OBD1 again.

F22(a, a1, a2, b, b1 etc etc)- Came out of 4th gen 92-96 prelude S, accords, and don't differ a whole lot from motor to motor, though some due come in DOHC - and again you need OBD1 conversion unless 96+

h23a (DOHC VTEC - blue top) Came out of accord SI-R wagons, again need conversion to OBD1, very similar to H22 motors as far as power is concerned. Very expensive motor.

The differences here, is your not going to have a whole lot of power with the F series motors, nor the h23a mentioned above in prelude SI's. The F22 motors are extremely reliable, and get great gas mileage. the downside here is that your not going to get a whole lot of power out of them. They are very turbo friendly if you have the $ though. They are also very inexpensive and are found ALLL over the place.

I'd type more but I have to leave work. Good luck in your decision, whichever choice you decide to make. Personally, i believe that if you go with anything other than an h22 your going to regret it. Your not going to have a whole lot of power under your right foot any longer.

Best of luck brosif.

Re: Need new motor. Which one to get?

H22A = all Japanese H22's, not just 4th gens. Type S, SiR S spec, regular SiR Preludes all got H22a's, same would go for the Euro-R.

F20b is from the Accord SiR/SiR-T and is DOHC VTEC. Basically a destroked 85mm non FRM H22. Believe it is around 200hp, so similar to a H22. Just less torque, but can rev higher due to the shorter stroke (88mm from recollection).

The H23a VTEC I think was only in the AWD Accord wagons (CF4?). Basically a H23 with a H22 head or a H22 with a H23 crank. Similar power once again, but more torque and less revy due to the longer stroke. Also only available in auto, something to keep in mind if you need a new trans to go with it.

You can pretty much swap any F/H series motor, excluding the S2000 F20/22C of course.

Re: Need new motor. Which one to get?

Thanks for the info guys. I'm going today to buy my JDM h22a motor. I need a new clutch and release bearing, would you guys recommend i should upgrade to a high performance clutch due to the increase in horsepower? Or just a replacement one?

Re: Need new motor. Which one to get?

stage 2 clutch on my car is sweet... but in traffic its annoying at first cus its on or off and u gotta get use to it...

if u like to drive ur car hard, or u plan on some engine mods later on, id say get a performance clutch stage 1 or 2

if u baby the thing and just use it for commuting or a DD maybe get a stock clutch...but i would def do one or the other while the motor is out...u will be pissed if u have to do it later after ur new motor is in

Re: Need new motor. Which one to get?

I think I will get just a replacement clutch kit. I don't think I'll do anything more than intake and exhaust, maybe headers down the road. Before that I'll be getting some exterior/interior upgrades. I just called the place I'm buying my jdm h22a, and they do have f22 series in DOHC. I'm thinking, should i go f-series? You said it was more reliable and fuel efficient... and its almost half the price. How many horses does f20b or f22b have that i'll regret instead of getting the h22a?

Re: Need new motor. Which one to get?

F22B is less powerful than the F20B. Both are DOHC, but the F20 has VTEC. More reliable I guess due to the iron sleeves, F series is more fuel efficient I guess because of the gear ratios rather than the engines themselves.

Power of the H22a depends what it is from. If it is from an SiR S Spec, then you are looking at 220hp.

A stage 2 clutch shouldn't be that much different from OEM. It's when you get to the unsprung/3 puck button clutches, etc. that you have issues.

On/off would mean unsprung? Anything stage 2 would be sprung I would have thought.

gear ratios? Doesn't the transmission determine that? My friend has an rsx, had bad highway fuel mileage so he put a tsx 6 speed tranny into it and now his 6th gear revs lower at higher speeds.

Re: Need new motor. Which one to get?

Yes, as I said "rather than the engine". I was referring to to the ratios of the transmissions that come with most F series engines. Like 4.062 final drive vs. 4.266. Plus the top gear as per your example. Can't really see any reason why an F series engine itself would be any more efficient than an H.

Re: Need new motor. Which one to get?

I just bought a jdm h22a. The guy originally bought it for $1200, but he never used it and I got it for $650. Is that a good price? As for the stage 2 clutch...what does it mean it come's on and off? I found them online for about $500-600...thats waaay out of my price range just for a clutch kit.

thanks Honda4lifeprelude. As for those stage 1 clutch kits are definitely reasonably priced. I think I actually might get one of those if it can get to me on time. thanks for the links
