Jade_Accord is cool... so far.
Cool Got A JDM F20A DOHC. Looking For More Information.

Hey CB7Tuner,
I got a JDM F20A DOHC from a very reputable sorce. The engine is from a 90-93 Honda Accord Si (CB3). I know its a direct swap into my 93 sedan. I've been gathering lots of information on this engine since I got it. I would like to share what I have learned but also ask if anyone knows anything.

-HP is approx. 150HP
-Displacement: 2.0 L (1,997 cc)
-Bore Stroke: 85 mm 88 mm
-Compression Ratios: 9.5:1
-Redline is believed to be 7,500RPM
-The ECU is a PT2 OBD1. I was lucky enough to find one. I'm guessing they're rare.
-The intake still uses butterfly valves. Even easier to set up if you have a USDM F22a6, which is what I had.
-Throttle body size is the same as usdm. (Personal research confirms)
-The exhaust is a 1.75in unlike our USDM which is 1.5in
-The timimg belt is strangely enough the same as 1988 dodge caravan 2.5 lol

Right know im trying to find out if it needs a knock sensor wired up and if the distributor is internal or external coil.

Any information at all about this engine would be greatly appreciated!
P.S No I'm not gonna just get an H-series. I already have this mint F20aSi.

Most of the swaps that work with our car have been fully researched. But glad to see you did your homework. You will find this thread will answer most if not all your questions:

I have a F20A DOHC. My distributor is OBD1 internal.

You could use any H series distributor on it. So just go with what your car has. Is your car internal or external coil?

as for Knock Sensor it does not have one. IIRC

What's the torque rating on it? I'm just wondering if its anywhere near an f23a sohc. I'm considering doing an f23a swap into my 90 honda civic.
