[brandy93]

Hi everyone!! I have some great news for all L20ET owners & HR30 owners with L20ET engines...I know this is a very very very very rare engine! For the last year or so I have been looking for an L20ET wiring diagram, all I could of ever find close to it was the L28ET wiring diagram which didn't help me. After searching and searching and searching everywhere on the internet including all these kinds of forums, no one could of helped me. I have found the original L20ET wiring diagram!!! It's the same 3 jack ECU, its for the L20E & L20ET...Don't mind I forgot what I searched for in google, but I found it in google images and I cleared my history already, anyways I have the diagram THANK YOU JESUS! The only problem is that is in Jap/Chinese and I need it to be translated ASAP!

I will post the diagram below and can someone please take it and translate it to english. I'm sure this will be very helpful to all the L20ET owners such as myself. W-12_HR30_L20E_L20ET_ECCS_1983.pdf

I also have the complete diagram for the interior of the car also, that needs translating as well. Let me know if you need it. Please translate this 1 to english. Thanks!

EBAY .................................. It's an L20A

OH! IF you want your L20ET to go like hell, toss it away and build an L24ET.

The ozzie L24E block has a front sump and the options are endless up to over 2600cc

All L series 6 cylinder engine blocks are the same external dimensions BUT!

An L20A cannot be bored to L24 spec of 83mm and similarly an L24 block cannot be bored to L28 spec of 86mm as there is not enough metal in the bores.

And L24 & L26 blocks share the same bore of 83mm and by using an L28 crank and suitable rods an L24 can be stroked to over 2600cc.

In the US, they have bored an L28 block to 89mm and created an L31, but not turbo, normally aspirated only as they have found in most cases, the bores are to thin and become porous when boost pressures from turbo charging is applied.
