JDM H23a Blue Top Swap - 2K Accord Coupe - questions, and hopefully answers....

[DC2-ProdUcTiOnS]

So my buddy has had his 2000 Accord Coupe for some time now and its taking a hefty beating...but since business has treated him good recently, so he wants to bring her back to life. New heart, new interior, new rims, new suspension, etc.. etc... The motor he is choosing to use is the H23a Blue Top long block with a T2T4 LSD transmission. He is going to be getting the motor/tranny from HMotorsOnline.com in the coming week or so and thats when the fun will begin...... So here are a couple of questions I have to make sure were going to have everything needed for this swap, and some parts to make this goes down somewhat smoothly..... The swap from HMotorsOnline includes the following: - Motor - Alternator - Intake Manifold - Exhaust Manifold - Fuel Rail - Injectors - Distributor - Engine Harness - Comes With All Sensors Needed - 5 Speed T2T4 LSD Tranny 1. Since the motor is for a JDM RHD vehicle, is this harness going to work in a 2K USDM Accord Coupe that is LHD. I've been told it wont reach to the passenger side of the car? maybe yes, maybe no? 2. What ECU should he be running for this setup? Ive seen people using P13, and P28...however, i think figuring out what kind of harness he needs is the first step in answering this question. ( Dont say the stock ECU cause its an AUTOMATIC ECU...) 3. Which axles should we be using to mate the H-series into the Coupe? Ive read that F series and H Series axles are interchangeable, but can someone verify this in this case??? If they are, does that mean we can use the stock axles from the F23 thats in there now?? 4. What kind of mounts are we going to need? Does is mate to the existing? or do we need a new setup? 5. Lastly, if anyone has anything to add that ive missed or that could be beneficial to know before we proceed with this swap would be greatly appreciated... Thanks for your help guys, im going to end up using this thread for pics of the tear down, swap, questions, answers and all that mumbo jumbo.... Help us bring her back to life..... Dc2

If they are, does that mean we can use the stock axles from the F23 thats in there now?? ACCORD FAQ - All F, or All H (axles and intermediate shaft)

It's close enough to the 5th gen, I suggest you read those FAQ's and pull the information you need. Not to mention a simple search yields:

^^^ most of your answers are in TheMuffinMan's post above. As far as the mount question, thinking that its almost the exactly like swapping an h22a, all the stock mounts mount right up. EXCEPT the driver's side mount. The mount bracket on the h22 engine has to be modified to bolt up to the accord's mount. I'm in the middle of the swap and the guy who was dropping the motor in (but didn't get it goin, its currently at a shop being built, n yes they got the wiring that the other guy couldn't figure out), somehow got a hold of a Euro R mount bracket n it worked perfectly....but i hav no clue wat the chance would be finding one of those brackets. We had dizzy wiring problems just to let u know...so you mite bump into that...or not...

[TheMuffinMan]

Yeah, I heard about the Euro R mount working for people, but it seems like so much trouble to source it when you can just mod an easy to come by one

[JC98]

Yeah, I agree with you on that......I still have no clue where this guy sourced the Euro R mount bracket that I'm using.

[DC2-ProdUcTiOnS]

well it seems my buddy has had a lil change of heart and now wants to get the F20B now....pretty much the same except for everything is interchangeable now cause its F to F....gonna throw that baby in there and boost it.....

we got the motor pretty much ready to be pulled and started working on the body getting it ready for primer....

updates soon....

how is the F20b interchangeable with the F23a? sure they're both F's but that does not make it more interchangeable than a H series motor ... it's harder to source parts such as pistons for an F20b if they ever take a crap ... IMO stick with the H23A VTEC ... sure the F20b is a high revver but it lacks the torque of an H23A and with a heavy 6th gen accord ... you want that tq ... the F20b has even less torque than the factory F23

[Phaulkyou]

For the drivers side mount, call www.dentsport.com

They have made a few drivers side mounts for 6thgen accords to fit h motors.

The F20b is basically a de-stroked h22. It was designed to compete in touring car racing where the engine size was limited to 2.0l. It makes good hp, but crappy torque. Id stick with the h22 or h23vtec.

[JC98]

agreed on h22 or h23^^^ n also, i asked the guy who did my swap, where he got the mount bracket, just to make sure, n he said he had one layin around from a swap he had done....he mentioned that the driver's side mount bracket was off of an h23a vtec blue top..so from the sounds of that, the h23a would've mounted right up (unless he didn't remember correctly where he got the bracket bt im pretty sure he did). But i guess you're goin another route now...but if you had the chance to get the bracket off the h23 that should help out for that driver's side mount issue.
