Hello from Germany,

so i have a Problem to identify a ej20 motor.
i try to search the ecu sticker but a tuning company put another sticker on the ecu :-(

so i found some cast/serials

EJ20

The numbers behind the altenator are 5 3 AB & AB 5 3

2 2 2 2 2

Blocknumber:

2 2 4 1 5 9 & 5 0 1 5 2 2


tranny: TY752VN1BA

the previous owner do a swap i cant use the vinplate

so here is a pic from inside the ecu:



Turbo castnumber: 14412AA09 4917808210 TD05H

thats all i can say about the engine

Sorry my english is bad.

hope somebody can help me.

I don't suppose the car's left hand side (standing in front of car, looking at the engine) black cam cover still has the silver sticker on it?

If so, its black text is the full engine number.

P.S. Your English is better than half of the 'natives' on here.

And a 1000% times better than my German.

rinaldo

thank you :-)

There is no silver sticker on it...

rinaldo

nobody can help?

i forgot its a 4CAM16VALVE with on bolt peer coil

It will be a Version 1~2 engine with 4cam 16 valve on the cam covers and coil packs mounted directly on the spark plug.
Version 3~4 will have a centrally mounted coil pack on the inlet manifold.
Version 5~6 will have the coil pack mounted to the right hand side of the inlet manifold.

EJ20G...

Open Deck Block (ODB), I believe..?

Could be Open deck or closed deck on a EJ20G (oct '93 ~ jan '96) joz
Cross hatching on the crankcases would tell for sure.
No 5th injector (V2 RA) on the inlet manifold, but the inlet manifold could have been swapped as never seen a version 1~2 sti/ra with a red manifold from the factory.

My guess would be Version 1~2 WRX or even an early legacy engine ( if it has 2 bolt holes for the coil packs on the cam covers) as the cam sensor has the long harness on it.

thank you for help!

so how can i identify that is a sti engine or wich hp or other specs?

the coil is with one bolt fixed

You can ALWAYS count on Mick the Wizard.

Mick, which phase-1 engined models had the CDB? I assume it's the STi II variants, no?

merlin24

Without stripping the engine to examine the internals, no way for sure to tell.

Mick

Bit of a lucky dip concerning ODB/CDB's, STi V2 RA did have CDB as did some of the real early STi V2 and Legacy's.
Some of the later production run STi V2's had ODB with bore squirters.
EJ20K from sept '96 onwards came with ODB's.

Interesting. Those crazy Japs.

Mick, is my STi V's EJ207 a SCDB, or a ODB?

merlin24

iTrader: (1)

ODB on the STi V5~6 from the factory ( unless the block was changed when it was rebuilt)

Mick

joz8968

Thought so. (I heard someone say it was a SCDB, so wanted to know for sure).

In your own experiences of pattern of failures, what seems to be an ODB's typical max bhp level?
IRO c.450-500, I'm guessing?

But I suppose either the OEM pistons or a bottom end failure are the weaker points (i.e. the limiting factors); not the actual block itself?

Have a groovy Xmas, Mick.

Cylinder pressure and boost pressure are the limiting factors of any block but have seen many ODB's around the 500 mark when they are assembled correctly.
As you quite rightly said above, the rotating parts would be the limiting factor on an OEM block.

Merry Christmas to you and your family too
