Call it siamese, or closed it's all the same. Got the head off the block. Just some info for the newbies

exactly what motor is that?

supermarkus · 10-19-2001, 02:16 AM

I think that's the EJ20 he was mentioning a week ago. OMG!

Eric SS · 10-19-2001, 02:18 AM

wow! look how much space is between those pistons!

yep it's an EJ20 first gen of first gen.

I took a couple pics of the oil squirters that shoot oil under the piston for additional lubricating. But they didn't come out good at all.

I'm wondering if I can bore and stroke it out to 2.3L

can the oil squirters be removed and placed on a 2.5 like they can on a 300z motor? (i think it was from the 93s and 94s on but whatever)

I think you would need to plumb the oil squirters right through the block, which is actually pretty hard. So I guess it would be no.
Hehe, one of the reasons I got the engine.

closed deck and those snazy oil squirters.

The answer is yes. The required oil channels are in fact in the same place in the EJ25 as the EJ20, requiring only drilling/tapping to install them. I know Cobb has done this on EJ25 blocks.

I don't think the oil squirters are for additional lubrication, they are primarily to keep the pistons cooler, which can reduce detonation...

The 2.0 blocks can be boared out safely to 2.4L. I talked to Tony Rigoli a while back and that what he has. He has a custom forged crank, rods and cosworth Pistons...Gerry

My 2.5 cents worth. The Just as mighty 2.5L block with closed deck.
