F20b DOHC swap in a cb parts list

Complete Parts List F20B DOHC VTEC swap in a CB7

Ok so first thing first is your going to need a engine. You can find one from most of your jdm engine suppliers online.

If your looking to completely tear down the motor and rebuild it you can get all your parts from here seeing as how to Honda doesn’t sell parts for this motor and neither does Auto-zone in the states. For a head gasket kit you have to get it from here only place that can get you one in the states THE H22 WILL NOT WORK they sell a kit and just the head gasket by its self.
http://www.autodynamics-honda.com/hopcbcyhegao.html
hmotors online sell just head gaskets by itself.
http://www.hmotorsonline.com/shop/wh...php?prodID=817

Now if you have a f20b motor its more than likely OBD2 and your CB is OBD1. But I will be covering the most logical and easiest option to get the motor to work in your car.

In order for your f20b to work in your accord you will need some parts listed below:
1) H22 OBD1 distrubtor- 31-17405
2) OBD1 H22 injectors- 06164-P0F-000 x4
3) A OBD1 H22 top half of the intake or a full h22 intake and If you wanna run a after market IM a h22 bolts up just fine. Now the reason for this is that it takes care of the IAC on the OBD2 IM being a 3 wire but your harness is a 2 wire. This will allow it to plug right up.


Now you have your new motor in front of you. Now your going to wanna do some things while the motor is out. Im doing a manual tensioner conversion and a new water pump and timing belt. Listed below are the parts you will need.
1) timing belt for a H22- 1400-P13-003
2) water pump for a H22-19200-P13-003
3) manual tensioner conversion kit- http://performance.importrp.com/manu.../i-291139.aspx

And this motor doesn’t have a vtec pressure switch so you will need to pull it off one from an H22 or take the entire solenoid.

Now for the ecu you will need. You will have to get a ECU chipped you can actually hit up drummersteve7 for a chipped ecu. He is a really good guy and is on this forum.
And other places to get a chipped ecu from is HAMotorsports they have cheap chip and socketed ECU's but they sent me a shitty basemap. http://www.hamotorsports.com/socketedp28.html
And then there is phearable.net who has chiped p28's also but is a little more expensive I just order a basemap from them the other day and will let you know how it runs. http://www.phearable.net/

And now for the driver side motor mount thats bolted to the head will need to be changed. You will have to find a 92-96 prelude DOHC timing side engine mount bracket so your Accord driver side mount will work. Honda has them for 60 bucks
part number-11910-P13-000



Most of my info comes from reading the F20B thread on honda-tech from the first to last post like 5 times. And other threads found on the internet. Because I will be doing the swap here soon and found most of the info over every where. And wanted it all in one place. So why not here.

When you say you need a "DOHC" driver side mount, does that include the H23? Thanks a lot for putting this together. The F20B was actually an initial plan of mine, but when the F died I was just worried about getting driving again so I got an H22 because of the amount of info on the swap. I still might do this some day.

The F20B was only offered in OBD2 Accords and Torneos. I'm pretty sure the proper ECU, if you can track one down, is called "PCB." But obviously it is OBD2 and probably not worth converting your gauges. This thread here also alludes to some major headaches. Getting a chipped ECU with a proper tune is my only real concern now.

Yea that one should work to. You can also use a f series but you can't use a bolt hole. Thats the reason I said use the DOHC one.

The link for the Honda PCB Cylinder Head Gasket Overhaul Set. Says its for 98-02 f20b. My engine is a 97. Are there any differences between those years?

Tcu to use with auto swap

After some research and trial and error I have found the best ecu/tcu combination to use in my auto F22b swap is a P78 tcu from the 94-95 Integra LS. The tcu's maximum WOT shift point is 7k 200 rpm short of the P39's 7200 rpm fuel cutoff. This has great part throttle shifting and maximum upper rpm shift points. In D4 the car pulls to 7K and 40mph in first gear and 2nd is a killer. The only down fall is the D4 light on the dash blink similar to using the 94-95 accord tcu, but drivabilty is not a issue at all.

Also when u get the engine it will have eithet the auto fly wheel or manual one. Get it from h motors tho. Tiger is kinda idk. I didn't like them haha. Mine came with a red top also. You could try this ask for the one with a manual fly wheel cause u have the manual transmissiin and meed that one to match and to the one with the bigger tb.
