I have a 1988 honda accord, which is a 3rd generation accord, 4 door, carberated motor not fuel injected, i want to swap the GSR motor in the accord. Is it possible to swap the GSR in the accord, and how much work would it be to make the engine run perfectly ?? And how many extra parts would i have to buy ??

 

I wouldn't recommend a GSR motor swap, because of $$$... If you insist on swapping a motor into your car, I would choose the B20A (the JDM motor for 3rd gen Accords).

I got the following information from http://www.3geez.com, and all credit for info goes to Joe, with the screenname "87accordlxi".

---------------------------------------------------

The B20A is the engine found in the 2nd Generation of Preludes and 3rd Generation Accord in Japan (and some Europe countries). This is a DOHC EFI engine.

This engine has 160 Hp and 140 lb/ft Torque

This is NOT the same B20A engine as the ones found in the 88-91 preludes.

The B20A from the Prelude will not bolt to the Accord. The engine mounts are totaly different.

You can tell appart the engines just by looking at them. The B20A for the Accord leans forward (towards the radiator) while the B20A from the Prelude leans backwards (to the firewall).

Here comes the tricky part. The engine from the Prelude will be labeled B20A5 or B20A(Japan) while the Accord engine will be labeled B20A (Japan) B20A2/B20A7(Europe). Both Accord and 88-91 preludes will have the B20A label without any other significant mark. It's really important that you look at the engine carefully to determine if it's the "correct" B20A

Both B20A engines have their own transmission. This means that the Transmission from the 3rd gen Accord/2nd Gen Lude B20A will not bolt to the 3rd Gen Lude B20A. The A Series transmission will not work either on the 3rd gen Accord/2nd Gen Lude B20A

The transmission numbers for the B20A are F2K5 and B2K5. This is easier to tell them apart if you have the numbers.


To do the B20A swap, you will need at least the following :
1- Engine
2- Transmission
3- Rear transmission mount (different from the A20Ax)
4- Wire harness
5- ECU


---------------------------------------------------------------------------------
Now just to complicate things more, there are 2 types of 3rd gen Accord/2nd Gen Lude B20A

It doesn't really matter which one you will get because they have both 160HP. The only difference is the intake manifold and valve cover color.

The 1st version of the Accord B20A has a gold valve cover and uses the same idle controls found on the 86-87 A20A

The 2nd version of the B20A has a black valve cover and uses the same idle controls as the 88-89 A20A

It's advised to get the proper version of that B20A but it's not really a problem. The A20A shares it's intake manifold with the JDM B20A. So, if you don't have the correct version for your EFI system, you can install your A20A intake manifold.

The B20A2/B20A7 from the EURO Accord is a little different, it has a lower power rating (137 HP I beleive) and has only a black valve cover for both versions. Some versions use a vacuum advance distributor like the A20A

----------------------------------------------------------------------------------

Update

There is a way to install the JDM B20A if you don't have the ECU nor he wire harness for it. Just use your A20A parts.

To do so, you need the following:
1- Integra 86-87 Distributor (if your B20A had electronic advance)
2-Integra 86-87 Crank Sensor (if you get the teg drstributor)
3-A20A wire harness (EFI)
4-A20A ECU
5-Prelude 90-91 exhaust manifold upper part if you have a 88-89 Accord (it needs 2 O2 sensor inputs)

Just hook-up those on the B20A and your engine should work fine. You won't get the optimal power but everything can be compensated.

There is also hope for the carbed guys.

Since the B20A shares it's intake manifold with the A20A, you can use your stock carbed intake and slam a Webber 32-36 DCOE on it. THis will make sure the B20A gets enough fuel and you don't even need to convert your car to EFI.

However, you will need to get an Integra distributor too if you want the engine to work fine under acceleration.

-----------------------------------------------------------------------------


The B20A share some components with the USDM B20A but it's really limited.

Here are the HONDA OEM part numbers that matched between the engines

Rings (both JDM and USDM)
13011-PK1-003
13011-PK1-004
13021-PK1-003
13021-PK1-004
13031-PK1-003
13031-PK1-004

Pistons (JDM)
13101-PH3-010
13102-PH3-010
13103-PK2-000
13105-PK2-000

Pistons (USDM)
13101-PK2-000
13102-PK2-000
13103-PK2-000
13105-PK2-000

Rods (Both JDM and USDM)
13210-PK2-000

Clutch (Both JDM and USDM)
22200-PK1-000

The pressure plate is interchangeable too but aren't the same part number

JDM
22300-PH3-J00

USDM
22300-PK2-000

The crank is a near match so it may work too.
JDM:
13310-PH3-010

USDM:
13310-PH3-020

So I can't confirm it's compatible but it's close

Oh an the ECU will not match but that doesn't mean that the prelude ECU will not be able to make the Accord engine run.

Here are the ECU numbers for the B20A (Euro version I think)

83305-SE3-010ZD
83305-SE3-010ZB
83305-SE3-010ZE
83305-SE3-010ZG

Here are part numbers for the JDM ECU
37820-PH3-063 (ECU 88-89)
37820-PH3-900 (ECU 86-87)

Everything else will be different and will need to be acquired with an engine importer

 

Does anyone know the compression of a b20? Reason I ask is for the 3rd gen owners to see if a FI or NA application would be more wise. I know with the displacement of the engine it would be good in either case....

But http://www.3geez.com is the bang and welcome to h-t

 

this is all i've been able to find so far:

b20a (from accord and vigor)
bore x stroke: 81.0mm x 95.0mm
compression: 9.5:1

thats a bit high compression if u really wanna see some boost potential.....god, i love the f22's low *** compression....

&lt;== patiently waiting a call from tuning shop regarding possible turbo app....mmmm....power....
