According to some post at accordracing.com there was a guy claiming that stock f20B can completely murder any stock H22a. I pulled the specs and F20B is a smaller engine that has 200hp and 157tq. Where h22A got 195hp(usdm) and 200hp (JDM) and 168lb of tq. So how is more powerfull engine like H22a being bigger and more torqy loose to f20b's?

Reason I'm asking is that I wanna do an engine swap to my accord soon and being an OBD2 i can swap an OBD2 F20B in my car and still being able to pass emissions. Here in MD it is illegal to put the engine lower than your cars year, which is in my case 97. So i have to have an obd2 swap in order to stay street legal and H22a obd2 swaps cost close to 4000. F20B can be bought under 3000. I need advice on what I should do.

 

First you should search. If you can't find it here, look in prelude FAQ. This question is covered mang.

That guy is full of ****.

 

Thats what I thought! /\

I did search and found out that F20b is a preety good motor. It DOES have the same hp as the H22a and it redlines a little higher. Overall H22a is a better engine for the fact that there are more stuff available for it. As well as price (for obd1) But as for me... the best bang for the buck, considering that I can only swap an OBD2 engine F20B would be my best bet!

 

you caould also look for an h23 (all h23's are non vtec) and that costs less than an h22 and the f20 and you can can slap a turbo on that h23 for some good power.

 

cant! .....it has to be OBD2!!!

 

OBD2 suxxorz

 

I agree h23's ive heard read nothing but good news. I once read about a person in MD slapping JE low compression pistons while sleeving the block creating a rediculous amount of horsepower.

 

You are overlooking the fact that H22s (and all engines for that matter) from 96 on are obd2.

You will be much happier with H22. You need to search more.

 

what car does this f20b come in? never heard of it S2k?

 

the f20c is the s2k motor, i believe the f20b is from the accord type r or sir

 

the f20b is good its from the jdm sir accord. that engine is worth every penny. but and this is a big but. the parts are very very very rare if u mess something up ur screwed. versus the h22 that every one has. i have called about 30 performance shops around the u.s looking for parts for the f20 to see if the local performance shop was full of it. he was current the parts are very expensive and hard to locate. i say stay with ur current motor and rebuild the low and top end for the price of the f20. if u cant find the kits for ur ride call a shop to make them

 

yaa you right... if something goes on that engine it would be a bitch to find parts for. Also, its not a turbo material i've heard. I dont know what to do with this whole emissions crap in MD. I really want to do a swap and go turbo. OBD1 h23 would be my pick but I cant have that bad boy in my 97. Sucks ***! 97 and up type S swaps look mighty fine with the 220hp red cover but 4000 for the swap..... hitting the pocket

 

f20 is a great motor but as stated the fact that if it gets broken your screwed...

i go tmine for 1500 canadian and its amazing to look inside it ..but if i bend a valve and mash the head i will just spend the 1500 again to buy the whole motor and part ou tthe bottom end ..theres always people looking for f20 crank and rods

i hope to make some good numbers with mine and hope its as fast as my h22 was ..but well see in a few moths

 

H22- More power, cheaper swap

 

not always true

for lsd tranny and f20 i got it for 2500 canadian ..so about 1800 us or so ...

 

the only parts in the f20b that are rare are the crank,rods and pistons...the block and head are actually identical to that of the h22a, using only different sleeves to make the 85mm bore instead of the 87mm bore that the h22a uses...the head actually uses many prelude type s parts because of the extended redline...

also, sure this motor revs higher, but it doesn't make the tourque that the h22 makes... also, good luck finding one with the lsd manual tranny...most of the motors on ebay are auto's, which are the motors with merely 180ish hp (as rated by honda with the auto trannys)...this isn't something you want to take chances with...

 

the head is a totally differetn casting ....
cams are p13 and cam caps are p13 and that it..ports are different as well as valves so i does pose a problem if a valve is dropped ...

but yea to make up for the torque diff it needs to rev ...

real 5 speeds are very hard to find i settled for an auto seeing as the only diff is smaller TB and suposed smaller cam but the auto cams are still bigger then h22 ,theres no eal confermaiton on the cam theory yet but i think jdogg moght have measuer them ...or mabye mugencf4......

as i isad i thikn the auto tranny eats up a lot of the 20 hp

h22 is probly the better swap as far as being easier but i did the h22 and now i wanted somthing diff....

 

f20b is a good engine if you are not going hard out with mods. Extractors etc are the same as h22a and it uses the same cams as the JDM prelude type-s (don't know if this exsists in the usa). Iron cylinder sleeves, very strong rods and pistons. I live in New Zealand and I have 1998 Accord SiR-T. It has an F20b and manual LSD transaxle. Personally I like this engine partually due to the fact it is so strong internally but if you were going to modify the internals of the engine you end up with you would be better off with a obd2 H22a. The F20b also has the same larger mains as the type-s prelude and has high 11:1 compression. Also have a nice blue rocker cover

if you got strict emission laws then the JDM f20b will fail as well. if its even close to being as strict as Cali SMOG then it will fail visual inspection instantly. if theres no visual inspection but if they do emission tests like they do in Cali then obd2 cars get smogged through the service plug and the JDM ecu will fail on that.

i see obd2 USDM H22 from wrecked or salvaged ludes occasionly and they are no where near $4k. but even with an obd2 h22 your gonna have to get around the immobilizer in which you have to use a JDM ECU which will fail smog or a usdm 96 p13 ecu which does not have the immobilizer but your cars a 97 and the 96 ECU wont fly with the emissions guy.

either way your going to have issues with emissions so get a jdm h22, and with the money saved on an h22 instead of an f20b, use it to pay someone under the table to get it passed.

 

Here in MD it is illegal to put the engine lower than your cars year, which is in my case 97.

How would they know? I'm in MD and am on my second motor which came out of a 94 and is sitting in my 95 accord. I'm about to throw in an h22 and have no idea what year that was from but I know MD won't either. Emissions doesn't check engines and after your pass the initial inspection you have nothing to worry about. Where are you getting this info about being illegal to swap a lower year?

In ur case its easier since ur car is an OBD1, so as long as the engine that u are getting is an OBD1 no one will ever kno. HOWEVER, my car is an OBD2 (1997 and up) which in the case of testing, they wont run my car on the dyno with the pipe attached to the back, instead they would hook it up to the OBD2 scannner. And Wham!!! Its not there! cuz the car would have to be converted to OBD1.... They pop the hood, and go HMMMM this is from an OBD1 car.... which basically means ur engine year is 96 or below... and thats wehre they get u.
