What engine should I build? Can I do this?
1) I have a 1.8 Sohc
2) I can get a mid 90s 2.2 16V
3) I can get a 2.5 long block that was "noisey"-any ideas what it might need? (warrenty replaced)
4) I spotted a DOHC engine in the core pile at the junkyard-don't know anything about it (4 cam pulleys)
I want about 200-250hp and alot of torque.
I was thinking of fixing the 2.5 and putting the DOHC heads on it (will they fit?). Can I machine a dish in the stock 2.5 pistons or are they to thin? Any other ways to lower the compression (cheap)?
Will a Subaru IHI work at all with this setup? How about a T3 with an a/r of .42 compressor and .48 turbin side?
What engine manigment should I try and get from the junkyard?

The stock pistons are too thin to dish I think. By the looks of my broken #4 piston the center of the piston is pretty thin.
The long block with the noise... may be pooched in the heads. Is the noise comming from the head area or the short block area. It may need to have valve train work done.
That DOHC enging may be the gem of the bunch. Is it a 2.2 ltr? if so, find out if the engine was a turbo engine. If it is and it is in working order, go for it. That's the one to get.
I run a T3/T4 Garrett on my set up and I make between 270-300 hp at the fly with 300-340 torque at the fly. Colder weather makes it more powerful. I run a built up 2.5 block with 8.5 to 1 CR. TEC 3 PEMS and parallel fuel rail mod 12 PSI with peaks to 14 PSI.
So, at the wheels, you should get close to 200 hp with 7-8 psi on stock internals with a stock 2.5 engine. Just make damn sure you get programable engine management to keep from breaking.

Well I just found out I can only get a 2.5 "short block" they reused the heads on the new engine.. So assuming they dignosed it right the noise must be from in the case.
How do I identify a 2.2, 2.5, or 2.0 engine form the others on the engine core pile? How can I tell if it was a turbo engine?
Is the 1.8 shortblock strong? I was thinking of using the DOHC heads and intake on it-just a thought.

There should be casting numbers and ID numbers on the side of the short block stating what engine it is. I am not sure what the numbers are for the turbo 2.2 block. You may want to post this question on another forum to see more answeres.

Top front of the block behind the power steering.
EJ25 = 2.5L
EJ22= 2.2
EJ20= 2.0
There may be more after the 22 like 2207 or 2204. I don't remember which one is turbo, but the size should be very obvious.

the noise is from the first batch of pistons, they weren't using offset wrist pins, so in the colder climate the got a little slap happy, it's a fine casing for building up.

My monster is based on a 2.5 piston slap TSB swapped casing (everything else is replaced)

That question involves some very serious thermodynamics. An easier way to get us to estimate a yes or no answer is to tell us which intercooler, and your estimated hp with your current turbo and with the new one.

i was at an japanese engine shop a few weeks ago and they were selling a my98 sti front clip for $2500. seems like a good deal. had the dash, ecu, wiring, engine, tranny, and everything, but driveshavft and rear end.
