Alright. Lets get started here.

The F20B only came in OBD2B, and it is a great motor. Same Hp as the H22, and Revs higher. The torque is Lower of course due to Displacement. 146 torque. The sleeves are Iron, instead of FRM.

The F20B is the same block, and head as the Over rated H22a.
The F20B revs higher, I am revving mine to 8200 at this moment, and it loves it.
The F20b comes with Ported and polished Intake ports from factory, and H22 Type-S cams. ($500 cams BTW)

The motor can fit in a 94 accord. Your accord came with the F22b1 or F22b2.
You can use your tranny and stock axles. Though your tranny sucks, sorry it does, due to the long gears. Best option would be to get Prelude tranny.

All your stock engine mounts will fit except the driver side mount. The driver side mount will need to be sourced from hasport.

Your stock tranny, and axles will fit. Your stock shift linkage will fit as well, no need to get prelude linkage.

If you have a Accord Ex with Vtec you will be already wired for vtec. If not you will need to wire in Vtec selenoid, and Vtec oil Pressure switch.

As for the Dizzy being OBD2b, You will need to get a OBD1 H22a Dizzy. It is alot easier!!

You can use a P13 ecu which is for the OBD1 H22a, but the F20b I have heard doesnt like it. Not to mention you will throw codes for the EGR, and Knock sensor.

I would up grade to a OBD1 P28 Ecu with a H22a base map, that is what I am running at this moment, and the car is running great. I got it from Phearable.net, John Vega. I am not sure if it will work for the Accord, but why wouldnt it, it is OBD1. Just call him and ask.

Other than that, It is a pretty straight forward swap.

The F20b is a grat motor, and I got a great deal on it. The OBD1 H22a will probably be easier for you. Just call around to engine importers to see if you can get one, I couldnt find one, since everyone is doing the H2B swap.

If you have any other questions dont hesitate to PM me.

Yes, it is not detuned, But just destroked. Same Hp, just different TQ. USDM H22a is 195hp, JDM 200hp, JDM Type-S H22 220 Hp, JDM F20b 200 Hp.

OBD1 H22a is easier. If I were you and I had your car I would go H22A since it isi easier, and you are new to this. If you want to Rev got F20B.
