Doing a f20b swap will our trans work

[dinks07]

Im looking to do a f20b swap already started taking out the old motor. i was wondering if i can use my stock trans and if anyone has advise on weither this swap is harder than the h22 swap and any opinions they have buying a motor saturday

[F22Chris]

I'm not gonna flame on this one, ALL F and H series except for the s2000 F20c transmissions will bolt up. Read the sticky. Actually, read all the stickies.

It's usable, but if using a f22a transmission remember the gears are long.

[deevergote]

Indeed. F22A gears are VERY long, especially for an engine with such a high, narrow powerband.

"Hard" is subjective. For someone with experience, it's not hard. For someone that finds it difficult to search the internet for well-documented information, it'll likely be very difficult.

What ECU do you plan on using?

[sonikaccord]

Are you going to replace belts, seals, and hoses too?

[illinois_erik]

youll need a chipped ecu also since its an OBD2 engine. dont use a p13 or other variant itll run,(after obd conversion) but not properly. physically itll be just like any other h swap. I might put one in my cd5 but the obd2 ecu complications (auto, tcu is combined in one unit) is kinda holding me back. maybe when i have a 3rd car to swap the cd out with while its pieced together.

it can be done just dont expect it to be quick or straight up like an obd1 H swap

like everyone else is saying, the long gears will hinder getting the most out of the F20b. It will fall out of vtec between shifts. So start saving for a better suited transmisison. In the meantime, the f22 trans will function and get the car down the road. A couple cliff notes on the swap: The drivers side post mount that bolts to the block needs to be swapped out with an f22a or h22 piece. If you're using the f20b alternator, you'll need a plug adapter or modify your harness to use the new style plug. Or you can swap your existing f22a alternator/bracket and crank pulley onto the f20b. If you are going to use the f20b intake manifold, you will need a 3-wire to 2-wire iacv adapter. Or you can just use an h22 upper plenum which already has a 2 wire iacv. For ecu, phearable can put an f20b map on a p06 or p28 ecu.

Wow thanks for the heads up does anyone recomend one swap over the other is the h22 OBD1 just easier i just finished pulling the drivetran and got time on my hand want it done right and no a hack job. Any input would be great if i get a obd1 h22 will the pcm just swap over or do i need to repin my ecu

You will find a very detailed H22A swap guide in the Swaps section of this site. Read through that, and we'll be happy to answer any questions you have.

In my opinion, the H22A is the best swap option available to us.

Different with this chassis takes quite a bit of money, skill or both.

I can't understand what you're trying to say. Please try to type like an adult. You're asking other experienced adults for advice. At least show them the courtesy of typing coherently.

As for being "different", the F20B looks EXACTLY the same under the hood. Nobody will know what it is unless you tell them, and it's really not all that uncommon anymore anyway (I've talked to literally DOZENS of people doing the exact same thing just to be "different".) The engine is there to move your car. Why do something that is more difficult, and potentially more costly, just to have an engine that makes less power overall?
That's like getting a super-detailed tattoo on your taint.

OK thanks for all your input. I will be going with the H22 being that there is more information and alot of aftermarket support for it.
