Question EJ20 versions

Does anyone have information regarding the difference in the ej20 engines. I'm thinking of getting one, but i would also like to tune it. Which version would be the best to tune, with minimal effects on reliability. I always assumed that the newer the engine, the better it would be. Thanks, any information would be greatly appreciated.

From what I've read, seen and ridden in, the version 3 is probably the best, the later ones (especially v5) have higher compression, making tuning and cranking up the boost potentially dangerous. BTW the v5 engines and later ej20s are the ones you hear about blowing up. What people did to the older engines to make more power is making them die on the newer engines.

From what I hear, the earlier blocks were sand-cast pure closed-deck engines. I think this info came from SPD's site (though I swear I heard it from somewhere else), and so may not be ENTIRELY reliable (nothing in the slightest against Mike, but he also said that the EJ25 would be unreliable with a turbo). If this is true, then I would propose this to be a stronger base if you're building an engine from scratch. They also might be quite hard to get ahold of since they haven't been manufactured for several years.

Hey Alwin, like the orange one on the cover with the bimmer arches eh?

You know, it's lucky you and I have the same dry/sarcastic sense of humour, or I might take the ribbing personally!

Hey Colin,
did you receive the info on the EJ20's? It would look like I'm going the EJ20T route with my quest for power. That and price. $250 for a 95% complete EJ20T is a strong inducement.

Sorry for the delay everyone... I left these in the resolution my fax-to-tiff engine generated so they are large jpegs but at least you can read them. DON'T embed them in this resolution on the board, it won't be very pretty.

Kyle's information:

engines
transmissions 1
transmissions 2

Seriously good stuff.

Good info. But, does anybody have the info on exactly what the differences are between, say, an EJ20G and an EJ20K? That is, I'd like ALL the info regarding the different blocks (not just those two).

For one the EJ20G had a 90 degree turn at the compressor outlet, just like the Legacy turbo. They fixed this obvious flow impediment in the EJ20K. The 99-up motors also have the PhaseII bottom end, with 7 bolts on the tranny bellhousing and the crankshaft thrust bearing on the #5 main.

I'm hardly an expert and I'm sure there is even more. Jay_UK would be someone good to ask.
