Does anyone know where the timing marks are on a 1990 Prelude 2.0 Si? That's the B20A5 engine. I don't see an arrow or colored marks like my Integra.

 

I dont know much about 3gen ludes, but if its like the 4gen and 5gen then its on the flywheel, not the crank pulley like youre probably used to.

What??

 

i think he mean how do you check the timing properly with the 4g ? I did mine and Im still worried that I messed up cause I never could find the plug your supposed to block off under the dash. Where is that?

 

should be somewhere close to the ecu on the passanger side.

whats this about timing on a h22a??? where do we check it at?

 

The ECU jumper is behing the center console near the gas pedal. It is blue in color. Here is a picture.



You are supposed to jump that before you mess with your distributor timing so it "blinds" the ECU.

You need a timing light to check your timing.

 

thanks 4bidden, going to go do it right now!

 

Youve got a timing light I assume then?

 

yes I do, where are the plugs, I cant find them

 

What plugs do you speak of? The ECU jumper is behind the center console on the drivers side. Reach behind there, they might be plugged into a dead end connector, just unplug it from there and you're good to go.

This location is for 4gen.

 

i only found 2 blue connectors, there go to a dead conection on that metal braket?

 

I cant find that grey one you have in the pic

 

found it, HELMS!

 

You need the blue one with 2 holes.

 

Checked timing, got the line on the flywheel right above the arrow that you line the dot up with. I dont know how many degrees this is, bt its prob just 1, cause its really close to lining up, just slightly advanced
