other vtecs?

[91kid]

Is there other DOHC vtecs besides the h22 and h23 that fit in our cars as easily?

there was a link in in the swaps thread to a possible swaps list but its a dead end..

thanks..

F20B dohc VTEC

[91kid]

Is that a good motor? or is it a major slouch compared to the others?

Geez, why don't you just sit in a highchair and let me spoon feed you more easily.

You do know there is a full section for engine swaps and a search button, right?

Similar to the h22a, but destroked to be legal for the 2.0 liter and under classes in the BTCC racing series. It can be tuned to 300hp N/A with enough money, but just seeing one of these swaps is rare. Possibly used a smaller TB on the auto versions with different cams to produce the low end power in lieu of top end power. The manual engines also had F20B specific cams, different than the auto versions, but not used in any other applications. Produced in smaller numbers than the other engines, but still not impossible to find, just a bit pricier. Usually look to spend between $3000 and $3800 for this engine w/ tranny, ecu, etc.

There is also an F20B SOHC that most non-JDM accords got and it only makes 150hp but is still the performance engine for a lot of markets.

The DOHC VTEC F20B is a fun engine nevertheless and since some people are in love with revs, this would be a nice swap.......if you aren't as worried about spending more and getting less as far as hp/tq go when compared with the h22a swap. These engines are better for N/A buildups than FI in stock form, but like any engine, they can be made to fit whatever your budget will allow.

PROS: different, more along the lines of the high revving b series motors than the traditional h and f series of the USDM, designed for racing applications initially from h and f series parts, so most parts are easily located.

CONS: more expensive way to 200 crank hp than a traditional h22a swap, harder to find a package that includes an LSD tranny and even harder to find an auto swap, but other trannies will bolt on from f and h series motors, OBD II (can be converted), peakier powerband but loves to be revved, boosting one of these high compression, open decked babies should be done with EXTREME care and some good tuning.

I got the quote from "the link to possible swaps" that "goes no where".

F20B DOHC VTEC is OBD2, we're OBD1. There are plenty of writeups on here on how to convert it. It's essentially the same as using a 97+ H22a.

thanks josh, your such a smart ass

btw cars looking clean
