I don't have any information on the costs of a swap because mine is a true VTEC, but I can answer your question about the long block.
A long block is just the H22A engine which doesn't include things like the throttle body, intake manifold, tranny, wire harnesses, axles, etc.
If you are looking to swap you would need the complete swap, not just the long block. The long black is for someone like me who already has an opperational car and may need to replace my engine due to engine failure.
Actually, that's not (totally) true, you CAN use the F22a tranny, it just has very wide gear ratios and you will probably drop out of VTEC in between shifts. You can use any tranny from the H22 and 23, and the F22.
If you have a F22 or H23, you can use your current engine mounts (same Part number for ALL models) and wiring harness, you will have to modify the wiring however. The F22 has the 02 sensor in the front instead of the rear like an H22, and is missing a few connectors like Vtec solenoid, Vtec pressure and knock sensor.
If you get a JDM H22A you can swap the guts of the distributor over to the H22a's distributor case to eliminate the internal coil setup, or splice the signal wires and use the H22's internal coil, it's up to you.
I have about 6 months worth of research into this project comparing part numbers and talking to people who have completed the swap, and I am beginning my swap this weekend. If you have any other questions, feel free to ask!!
Sorry.. one more thing, Here's the gear ratios for the three tranny's and the tranny codes.
F22A1
1st:3.307
2nd:1.809
3rd:1.230
4th:0.903
5th:0.705
r:3.00
Final drive: 4.062
Tranny code: M2L5
Actually Kevie is right! I had a Type S and swaped the old engine for a jdm h22a. I bought the long block and kept my old tranny. The tranny is fine except I cant keep the VETC engaged continueausly. I bought the long block from Steve at www.hondamotorsonline.com. I had it installed at www.pacmotorsports.com. All together it cost allmost 4G's. GET READY FOR VETC!

interesting, i thought due the the different blocks it would be different. BUT the f22a and h23a motor mounts are different, I just finished a swap not to long ago from f22a to h23a and we had to use the h23a mounts
Must be different for Canada then, because the part numbers for the front and rear mount plates that bolt to the engine are the same (I checked today at the dealer).

what about the side ones? I pretty sure those are the ones we had problems with
Do you need to lengthen the wiring when installing a JDM engine in a USDM car due to the LHD/RHD conflicts? I know this is the case on some civic swaps, but was unsure about the Prelude. . .
Yeah, that could be.. I have a bunch of them, I have 2 H22 side ones and the stock F22.. I'll compare them for you when I do the swap this weekend! Maybe if I can I'll post some pics. When I get working tho I don't wanna stop to take pictures!

The JDM H22A harness is of no use to you except for some connectors and things (I'm clipping the wires and using the connectors for the circuits the car is missing). If you are doing a swap, you will need a USDM H22A harness, or mod your stock harness to work.
SO in order to replace my F22 with an H22, I need BOTH the JDM and USDM wiring harnesses? Will a USDM H22 harness plug directly into the USDM F22 harness (I know you will still have to add a few wires)?
Um, well, you don't NEED the jdm harness, but it's nice to have those connectors and such! I think you can buy new connectors at a dealer.
And yes, the USDM H22a harness plugs right in. That's the way I wanted to do it, but no one wants to sell their wiring harness! (I wonder why? )
Well Kev I can confirm for you that the mounts are the same for the 92-96 preludes, no matter what model. I also did this research 2 years ago when I did my swap. The flywheels are the same...the fuel rails are interchangeable.....a lot the stuff is the same.
The H22A (USDM) wire harness will plug into the S model chasis without a problem. You just need to add a few wires like kev mentioned. This is where the JDM harness is handy because you can use it to take the connectors off of....and pin placement.
By the way, I can stay in VTEC in almost all gears with my S tranny. the First to second shift is iffy....40mph in 1st, shift to second, 50mph VTEC engages (73mph top speed with 2nd). 2-3 shift stays in VTEC as well as 3-4 shift. However, I have never experience 4-5 because its too fast for me. I did 130mph in 4th gear at 6500rpm. I still had redline and 5th gear to go....wonder what the top speed is on this tranny....hehehehe....my guestimate is 160 provided conditions are right, and theres not too much drag on the car.
Hey Kev feel free to email if you run into trouble. I will be around most of the time. If you have yahoo, you can message me at skillysbro, or email me at skillysbro@yahoo.com.
Good Luck and take yer time....especially when you get to the point where you remove the engine. Make sure you get the little sensor on the power steering line, near the axle....I busted on my friends when we took his engine out, and almost did it on mine. It doesnt mention it in the manual....bastards. Oh yeah be careful with the shift cables too.....
You are gonna have fun.

I may just do that Dave.. I should hopefully be OK!! I noticed that sensor in the P/S line so I'll be sure to remember it!
I'm pretty pumped. Hopefully I can have it done by Saturday night, but I won't rush myself. I can do a motorcycle in about three hours, but I'm used to those!
