Default 94 legacy turbo engine

I wasn't sur eif this should go in the factory or aftermarket.

I am looking into this engine and I want to run it with my Phase II 2.5 heads and a Ludespeed stage 1 kit (Will upgrade it as I go along).What i wanted to know was if you guys thought this engine would be a good solid bottom end,I dont know anything about it.Is it a closed deck?What company makes a good rebuild kit?

I plan on running the Ludespeed stage 1 but I have a JDM spec intercooler for it from a WRX GC8 body.

Is the engine new or used? If your going to rebuild it, you may just want to do it with factory pistons and such, as it can take some pretty high boost pressures.

I am not sure how the intake runners compare to the EJ25, but the EJ22-T intake manifold may sit further forward, resulting in allowed fitment of the intercooler. If its a MY 96 or EARLIER, it WILL definetly fit.

Used ,but it most likely will need a rebuild.I was thinking of boring it to stock EJ25 specs and getting the forged pistons and rods along with the engine prep being done.

you will still have to make some modifications to get a MY97 + to fit. I got a '02 US WRX intercooler to fit....it's tight

If your gonna do that, you might as well just buy an EJ25 and build that up, probably the same thing and you don't have to pay for it to be bored out.

Yes but I have to pay to get the deck closed,and a used ej25 will end up with a larger bore and I dont want the bore to be any bigger than the stock ej25.Any bigger would make the combustion chamber too large and wont allow fuel to fully anf efficiently burn.(imn my opinion of coarse)

I bought one, but don't see the hugh benifits of the EJ25 SOHC heads.

I was going to do an EJ25, close the deck and upgrade pistons rods and valve springs and lower the compression in the process.

I then realized that a EJ22T out of an early turbo Legacy is closed deck, lower compression already and can support the boost I was planning to run... plus per Dale Teagues it has forged rods and a hardened crank (I think rods are the same as most EJ engines)... So I went this it as this will save money and all I'll have to do is just valve springs now and possibly some minor head work. Should do the job.

I say get it, but take your time choosing your peices to put it all together. I don't see the need to buy a turbo kit when you can get most of what you need and better items for less than kit costs. up-pipes are different from EJ25 manifold altering verses the turbo manifold and DP might be the same way as well. SO those parts are worthless in this application.

Just my $0.02 of course though.
