Well, i've searched and read everything I can about the f20b, and it sounds like a very VERY awesome platform! With the recent introduction of the townsend brother H/F to B kit, i'm going to be swapping one into my DA! I'd like to hear everyones thoughts on this motor, how well it takes to basic performance upgrades, etc. I've seen the guy that made itb's for his, but I never got to see the video I'm very excited to be getting this project underway! So anyone that has some input about this motor, speak up! Here are some pix of my DA that it'll be going into...







So, lets hear some input!

 

great idea for a swap an f20b should be great in a da the only problem is gonna be converting your da to obd2

 

Thanks, and I plan on converting the motor to obd1 and use uberdata or chrome to tune it with. Ultimately, i'm going to end up using an anr header, hopefully make some 954rr throttle bodies work, and possibly rocket motorsports cams and valvetrain

 

Anyone else have comments?

 

many people will say the f20b sucks ...i love mine
they will also say that toruge is where its at ...dam them but there kinda right lol

but the f20b is a great motor it moves my heavy *** accord pretty dam well ..ill be getting to the track soon i hope ..all in all i like it better then the h22 i had
it responded to the itbs way better ,its alittle weak from 1500 to 4000 but i thikn its my tunnign (no wideband yet ) but from 5200 and up its fun,and the sound is amazing .

to put it in easy terms it feels like a big b16...with more toruge of course . From 5200 to 6500 it feels like regular vtec but form 6500 to 8000 it pulls very hard ,its the motors sweet spot (im sure its due to the rod strojke ration favoring higher rpm to be more effecient .

ill try to get some new vids up next week as its runnign abit better

i tihkn its a great platform to start since it doesnt need any bottom end work to be a strong mootr .its very well built

any other questions ask away

 

I want one

 

Why not just get a h22 with a B-series tranny? the f20b seems to be a nice platform though.

 

the down side to the f20b is your gonna give up some torgue

up side if your on a budget is stock 3 angle valve job better port casting then the h22
larger cams
higher compression
likes to rev,makes it a fun motor
and they seems to be pretty cheap if you find the right place ..i think it responds to mods farily well consideing its size

all these guys runnign same bore and same stroke in some b20 call them torque monsters but they call the f20b torque less lol ..
i bought it becuase i didnt have money to build my h22 so i got the f20b with a great stock bottom end ..if all goes well i wont have to touch it .

 

or why not a euro-r...

all that plus more power and torque and a short geared lsd tranny

 

unfortunitly the tranny is no different then a 5th gen lude it does have a shorter 3rd i belive (havent looked into the gearing for a while) but lsd is nice mind you very hard to find.

 

The budget is a major point for me getting the f20b. Although that is what started me looking at it, I don't think that i'd even consider an h22 after looking at all the bonus's the f20 has from the factory. I don't plan on opening up the motor, just putting on some nice quality bolt ons, and a good tune. My buddy said that on a stock motor, you shouldn't use less than 52mm throttle itb's. I'm wondering how the 954rr 42mm itb's would work out for me. Not after anything crazy, hopefully 210whp after cams itb's, nice header and tune. Lets hear your thoughts! Plus, how many people have this thing in a DA Anyway, i'm at lunch right now, gotta get back to work. All comments appreciated!

Opinions on 42mm itb's? I'm ordering my motor on monday, unfortunately, the H/F2B kit is $919 for my car, so it'll be a little while before I get it in, but i'll keep everything updated!

 

42 works ok on my car but it still feels liek theres more in it,,it oans off a bit up top ..but if tis budget then 42mm will work fine

i wouls go 50mm if i could afford it

 

Sounds good, but would you say that the 42mm itb's offer more than a euroR intake manifold? Even if they just give me 2 or 3 whp more, i'm going to do them. I've been into turbo stuff forever, and this'll be my first na "build" Itb's have always intrigued me, and i'm really looking forward to this project

but you are untuned correct ? throw an s200 system on there and have it tuned and youl realize its full potential

42mm itbs will be great and make much more than a euro r intake manifold by atleast 10 whp but make sure you get it tuned professionally

 

im half *** tuned ..i run crome and have street tuned with my **** ball a/f gauge and alot of plug checking ..its not bad .i can get about 30mpg on the hyway and it still runns rich..but i cant wait to get my wideband as i know it will bring more out of it ...

although i had a great idea for a miata buti have a hard time parting with my car

Exactly what I wanted to hear. And not to worry, i'll definitly have it tuned professionally. Oh, and I talked to the motor importer today, and I am in fact getting the m/t motor, not the a/t! I'm going to be running a b16 tranny as well, since i'm using the townsend brothers H/F2B kit! It should be pretty awesome, don't ya agree?

 

f20 the same motor in my accord wagon? if so, that motor got some torque and moves my heavy *** wagon everywhere............ **** has 300k and still running strong mad respect to taht motor its been thru hell and back and held up.


isnt bisi running one in his race car? that **** can pull that **** in a da should be nice, let us kno how it goes

No doubt man, i'll be sure to!

 

I really like the headlight shots

Haha, what up ole smeenan?

 

if your gonna run the h2b adapter plate anyway i would have to say goin with an f20b is a waste. the f20b may have a factory three valve job or whatever, but and h22 has a 1mm advantage in valve size. Now that does not always equate to flow gains but the h22 is very well designed engine as is. there have been a number of 250whp stock block setups. Your ITBs are a bit small, 42mm itbs are good to about 56BHP per throttle body. not to say you shouldn t go the bike ITB route, but i think some gsxr 46-48mm bodies would be better suited in your application. and if you just intend on hacking up a manifold and welding on some super crooked tubes with the wrong angles etc. i wouldn t waste my time. buy an h22 longblock have some headwork done, bump the compression with a mill and some welded chambers, gsxr ITBs or euro R manifold along with a decent header and cams would be a force to be reckoned with when attached to a b16 tranny

 

nice pics......


civicdx nice avaayyyyyy.

Thanks for the comments guys, I'm still new to all motor stuff, but I'm totally sold on the f20b since i'm on a budget and I don't wanna open up the motor right away. The reason i sold all my turbo stuff is I wanted a nice reliable car thats quick. I bought an r6 so, thats my real speed machine. I've been reading up on diy itb's, and i'm finding that gsxr1000 itb's look like the way to go, or even hayabusa itb's. Again, thanks for all the comments, and keep them coming!
