Re: need help f22 to h22 swap

The only difference with the JDM H22A is the compression. So everything will be the same as it would when swapping in a USDM H22.

Re: need help f22 to h22 swap

a few things.....

things JDM h22 has that USDM does not.., and vice versa

JDM h22 has fuel rail backwards.., along with wiring for RHD cars., you will have to use your F22 wiring, and mod where needed..., also JDM h22's have a evap purge valve on the fuel rail.., you will notice fuel pressure regulator vac line runs into it.., take evap purge valve off fuel rail, and run the vac line from fuel pressure regulator straight into intake manifold... you already have evap purge valve...

JDM h22 has only one temp fan switch..., your F22 and usdm h22's have fan switch A and B
H22 JDM and USDM have knock sensors.., I'm pretty sure F22's do not
JDM h22 has internal coil distributor (same as civic SI)
JDM h22 also has IAB's intake air bypass (butterflys)

if you happen to get a JDM h22 from an accord type R.., you will have no vtec pressure sensor.., just a bolt in its place.., you can either get one, use a power steering pressure sensor, or wire it like the accord type R, and disable it.., (ecu does not look for it) not ghetto, real oem wiring config to disable pressure switch.... and the intermediate shaft from an accord type R is different..., I had my axles made for an H22 from a prelude..., when I got my motor, I found out it was from an accord type R.., rear mount, and intermediate shaft were different.. I found out that there is no difference in HP between the two.., accord type R's also come with a P2T4 tranny.

when doing swap..., don't worry about wire colors, just worry about what ecu pin they go to

the rear mount with JDM h22 from accord type R is different than preludes.., your mount will probably work

when (and you will) run into problems...., thats what all these fine people (including myself) are here for....

hope this helps...,

You busted me out the first time haha. I just never really looked at the JDM H22A closely.
