You dont want to waste your time with frank swaps with the H/F series... Obtain the full motor and gearbox to extract its full potential...

I use to own a 5th GEN Accord EXi, H22A conversion was done to it...
If anyone needs help ill be happy to shed light on it...

Currently working on Project BMTDC2
DC2 Chassis with a All motor H22A (using JUN internals)

Is this to be a drag or track car?

Most likely track, it would be a good all rounder on the street, circuit and drag...

Is that an alloy block?, cause i've heard the increased weight of the H22 really upsets the balance of the car.

That's what i was thinking, the H22A is a much heavier engine than any B series and so I would've thought wouldn't be as suitable as a track car. Drag car, yes it'd be brilliant for it

Depends on the weight distrubution....
The H22A is ~ 45kg heavier then the B series engine...

The engine mounts will be slightly modified to allow the motor to lean more towards the firewall which will shift most of the weight to the centre of the chassis. There is a difference between adding weight right at the nose of the car and weight at the centre of car.

Most of this additional weight will be made up for by using lighter parts such as carbon fibre hood..

the F22B engine shares closer comparisons to the H23 engine, as parts from the H23 and F22 are interchangable! as with upgrading a vtec head to a H23 can be done, this is also possible with the F22B but with mods though.....

Mating a H series head onto a F series block can be done but at the price it cost to do so will be a major put off for anyone who tries to do it...

the h22 and h23 are same in dimension.
btw, an accord with a stock h22a is about same speed as a vti-r teg with same mods, e.g. catback

i have a fren with a H22a accord
its pretty quick

but in terms of potential the b-series motor i believe has more potential
then the H22A

beware if u see an accord with a vtec badge
its really H22A VTEC!!
hehehe
