diffrent oil sump?

[Turbo Haraune2]

I've found out that my EJ20 is not as ordinary as I first tought..
First it was the heavy duty engine block with closed deck.
and it has got bigger fuel jets, different turbo.
And it is pumping out 244hp at the wheels!

And now i also foud something different in the oilsump:
Lots of baffles and air/oil separators, and anti cavitation plates surrounding the oil pickup.
I belived the standar oilsump was just a steel bucket!...??
Or are my oilsump diffrent too?

I think i have got a "RA" engine!! (race altered)
among the subaru nuts this is the holy grail when it's talk about engines

That's always good news! I also have a closed deck block but it was out of an jdm automatic wagon so I have the standard turbo and injectors (for now ) As far as the oil sump goes, when I took mine off to put the shortened sump on the stock one had quite a few baffles in it surrounding the oil pickup, so I'm guessing yours is a fairly standard one, but I could be wrong.

Do you have a drawing of a shortened sump? I am in Thailand and it is impractical and very costly to import one, so I have been thinking of giving it a go myself.

Using wings like a Moroso style SBC pan would make up for lost volume

An easy way to check if it is an RA is if you have a fifth injector on the inlet manifold by the throttle body (not actually used on road cars).

This was used to inject fuel by the throttle body?

You're right about the SBC moroso style, this one was made by a friend of mine. You bolt the aluminum plate to the original oil pan bolt holes on each side, and then the steel pan at the uses the outside bolts (obviously) and shares the front and back original oil pan holes with the plate. I don't have any drawings of this but when I get home I can get some general dimenions if you want, and possibly build a general model of it in 3d cad.

Wow, sorry didn't realize those pics were so huge.

Yes, you can see it on this pic of my intake manifold. It was only fitted to road cars for homologation reasons, it wasn't actually controlled by the ECU.

Sorry for keeping the post off topic but, why would you want to put fuel in there? Wouldn't there be more of a chance the fuel would deatomize by the time it got to the cylinders?

Where is it?? (the injector)

I dont see it on yours..

If you look right in the middle of the manifold you can see a rigid pipe with banjo fitting on the top, just to the right of the 3 small black pressure pipes, you can just make out the grey connector to the injector to its left.

A fifth injector upstream is a cheap/simple way of upping the fuel requirements. They are commonly used in aftermarket upgrades if the standard injectors can't cope with the upgraded power output. As there is only one injector the amount of fuel in suspension is relatively small in the manifold. If adding aftermarket turbo/superchargers you can also use the fifth injector with an aftermarket ECU to add in the extra fuel and leave the stock ECU alone.

A CAD drawing would be great - thanks
