go with the H, the F20B has to rev up like those gutless B's to make its power.

with a lack of torque down low, not to mention the lack of aftermarket support for f20b (although a lot of f and h series stuff may work with it), plus lack of experience on ht with it, plus its more expensive

go with the H22. not only will you save $$$, but you'll also be saving yourself the headaches of converting it from OBD2----&gt;OBD1.

So the K20 is an OBD2 engine?

H is much more practical, more power, more torque, fits directly etc.

some people dont look at the whole picture ....

yes the h22 has more tourge ....but its only like 8 ftp and the f20 comes in 1000rpm later ...thats not a big deal ...not to mention the f20b has shorter gears to make up for the diff in trq......

for those on a budget (ie me)am taking the the f20 over the h22 (i have a jdm h22 in the car now) and heres why

the stock bottom end on the f20b is as strong as most after market parts..if not better due to hondas close tolerances ....in my case i will never have to upgrade the bottom end for my all motor build......even if i was going to there wouldnt be much use due to the fact that the rods are super strong ...

another plus is that the f20 uses larger mains 55mm vs 50mm(97 and up h22 use these mains too) a fully balanced bottom end and not to mention iron sleevs.....and no real need to resleve for forged pistons..

tranny has lsd on all 5 speeds and not to mention that the f20 is more then like ly in better condition due to the age ..(they were only made from late 97 to 99)

on the bad side if the worst hapened it would be dam hard to get stock internals or valves since they are smaller then the h22 ....but as satansrv has found there is a lot of other honda parts that will fit this engine nicely

i found many f20b for around 3000 and h22 for any where from 2000 to 2500

so for the small amount in difference and the fact the motor is newr in age its not a bad trade off

dont get me wrong it took me a long time to make the decision to go with the f20 but after installing my DIY ITBS on the h22 the rev potential of the motor was really a nucance ...so i would have to build my h to work with the new power band and that would cost more then i have .....

it bugs me when evey one calls it a torqueless wonde like b16s and such whn they really have no proof of it ..ive seen some dynos of f20bs put out 214whp with a ported head jun3 cams and an image header and almost 9000rpm with a broad power band ...never seen a stock block h22 make that power before ..in fact its hard to find many over 200 whp with more mods .....

that motor was build for one purpose..mugen needed a 2.0 motor for a race class and the of course were over with the h22...i thkn there was a stock block rule and thats why it was build so dam good....and these motors were making 300whp
it was also the test bed for the f20c (s2000)
and we all know its a great motor

so do some reasearch before making your decision ....if you think the motor will suit your driving habbits then great ..if its down low toruge you want mabye a stroked h22 is what your after ...me i want to make as much power as a can on a modest budget and with the itbs the f20b with a smaller head gasket some good cams and prospeed header should be great get me to my goal of 13.5 with my accord ........hope there was some good info in here for you

thanks for the help everybody...it will be a tough decision though!

stick with the H series for the parts availability

i would jus like to say that machine4321 ownz

i personally love f motors and plan on droppin in the dohc f22b once i get "sufficient funds"

f is a great platform for turbo

only reason i would say go with the h22 is parts are so easy to find

umm i think i read a post that said the h22 is a str8 drop in?? wouldnt it be the other way around? good luck with everything

Yes the F series engines are usually good for boost, but that is because most of them don't run 11:1 compression like the f20b does. the f22b and the f20b are very different engines.

as was said before the f20 does have some of the higher strung characteristics of the b series motors, but it is by no means gutless at the low end. If you want a good boosted motor, go with the f22/f23 motors, if you want a great all motor engine go with the f20. but you also have to keep in mind that you are putting this into a 4th gen accord (OBD1) and the F20 is an OBD2 motor. I have put one into a 6th gen and a 5th gen and loved them in both, if you get the ECU, full wiring harness, tranny and everything else, i can't see it being a problem. The H series can be both OBD1 or OBD2, so you could go either way. In my personal experience with swapping the f's go in a wee bit easier than the h's, just due to the driver side motor mount, but then again, i've never done one into the 4th gen accord either.

and by the way, f20s are not more expensive than h22s. go to http://www.jdmsource.ca and they have f20s for $2000 US, with everything you need. I've been to their shop, and the stuff they have is truely top notch.

hi there.... i own a jdm torneo sir-t, i live in auckland, nz. thats why i can get that jdm model.

anyway, not being OT, mine has this f20b motor in it. honestly speaking, it is a great motor. love to rev high, but still a great performer on city streets.

according to what i heard from my friend, who own a similar car (jdm accord sir-t), with cl1 euro-r's h22a (practically the jdm prelude sir type-s), f20b is actually a destroked h22a. f20b will pulls like mad on high rev. on low end, its lacking a little bit of tq. but hey, its easily recovered by downshifts the gear. as for the h22a, it's something like a more balanced motor across the rev range. great torque down under and massive power (220hp max) on high rev.

both engine is similar, most parts and after markets are interchangeable. so, its down to you.

agree with what had been covered above, f20b is a better option, since its the recent range. nothing below 1997 mark. so, good on mileage.

happy choosing......


thats f20b in my torneo

DOHC F22B + boost......any takers???

I think you should do the H22 cuz it's more of a challenge do to the weight! Plus more torque!

******* die now please.

i think the h is a better choice....and like everyone else is saying...more more more more more aftermarket parts...not to mention...will after market pice and a good tune with uber or hondata..you can make 215-230 whp..i cant pin point an especific thread with this proof but almost everyone in here knows this is true..peace

I have a F20B on my custom civic. I just put a custom SS headers with hybrid T3/T4 turbo and spearco intercooler with 35mm tial wastegate. I have RC 550cc injectors and the ECU will soon be custom tuned. I know that my compression ratio is very high and I wanted to bring it down to 9.0 to one or even below. Do you know where I can purchase s head gasket (thicker) to reduce my comp. A stock head gasket is also fine, I want to double stack the head gasket to reduce the comp. I've also heard that the only other way is to custom make the pistons since nobody makes forged low comp. pistons for the F20B. Any suggestions?
If I go through the custom pistons than I also require new head gasket as well. help?

id say h22, but its pretty pricey. i have an h23 for sale let me know, you could also do h23 vtec
