Arrow should I sell my EJ25??

Now that the EJ22T is almost completed, should I sell my EJ25 engine?

I wasn;t sure where to post this but I feel at home in htis forum. For those that didn't know, I blew the #4 "B" piston in the EJ25. I got it pulled apart and besides the obvious plown piston, the only damage is some scuffing of the #4 cylinder bore. So, what would you do? Sell the EJ25 shortblock (minus pistons) and be happy with the EJ22T or save it and slowly build it up (close deck, J&E piston, Carillo rods, etc.) untill it is complete and then through it in the car? thanks guys

Shiv sells a lovely fuel rail and upgraded FPR. Should solve the problem with the stock fuel rail nicely.

Oh, and I'd sell the EJ25. If you blow the EJ22, buy another one

I was having the same dilemma, the problem with selling it is that I really like the displacement and if I save enough or need to I would close the deck and get forged pistons and rods on the EJ25 man that torque… I have the EJ22t and I still feel like I need forged pistons and tune the heads getting different valves and springs etc… but if I’m going to crack open the motor… I’d like to have the EJ25 with 8.5 or 9 compression pistons.. ah decisions decisions…

The advantage with the EJ22T is that it has a superior rod/stroke ratio (1.74, same as the EJ20) to the EJ25. For a high boost application, that is a valuable feature.

Keep the EJ25.

I am a huge fan of the dispalcement that the Sube 4 offers. Take your time and slowly build this engine to something SWEET! I would try to do some head work, uprgade cams, and upgrade the valve assembly of the engine and make this a high revving turbo engine. Think of the power you could have at 7000 RPM with an EJ25 turbo motor.

Take It Sleezy

guess its a matter of taste...

what is the degree of rod stroke difference between the EJ25 adn EJ22t. I was wonder how big of a different of boost you can run on both engines with the same strength rods and pistons.. does it also depend on compression ratio of pistons too...?

The compression ratio is the major determinant, the r/s ratio comes into play on the stresses applied to the rods, especially at high RPM.

See my little table here .

Not much of a difference IMO, it's not like we're comparing the difference between a stock 350 and a stock 400 small block-- ah, sorry to use the Chevy analogy.

I'll take the increased displacement, thanks. Especially if you're spending money for aftermarket rods & pistons.

Wow, I wasn't aware you could turn an open block engine into a closed one. What would that involve? Labor-wise and cost-wise? Would there be any disadvantages? I'd imagine so, otherwise the EJ25 wouldn't have an open-block right?

Unless that was just a cost-saving feature for Subaru.

Cobb closes decks for $995. They weld material into the deck, leaving coolant passages. It looks almost exactly like a factory closed deck, but with big bores.

Of course I've been there!

I didn't see that part of the site, I guess. No one answered my other question, though- are there any downsides to closing the deck?

Downsides to closing the deck:

Expensive
Adds weight
Reduces coolant volume around the cylinders

Who says you need coolent flow around the cylinders? As long as you get coolent to the head you don't need the cylinder walls.If you really wanted to you could fill in the water jacket with Hardblock "which would be ideal" and just run coolant lines to your heads. The engine will run a little hotter but not that much to do any damage..Gerry

Keeping the motor cool in a high boost turbo application is a good thing. More coolant contact is good.

Although it does slightly reduce coolant volume, you pick up metal surface area which helps discipate the heat
