Default turbo advice please

anyone know if a turbo can safely be put on a 1996 2.2l L Coupe Impreza? If so, any suggestions? Thanks!

4 pounds is safe if you do it right.. then again 9 pounds should be safe if you do it right too..

I was running just 4.4 lbs of boost and POOF! So, 4 lbs can smoke your motor as fast as 9lbs. You MUST use some sort of timing control to avoid a massive internal failure. Trust me when I tell ya, do it right the first time or it's really gonna cost ya. I am at 3k so far for a rebuild. I havn't even purchase the PEMS yet. Ouch! Do it right or else...

Even if you take all the precautions you can, things can still happen. I went the extra step to be on the safe side and got a tec II and redid the fuel system and my engine still gave way at just 7 psi. Its not totally blown yet but it might as well be, I've been babying it to try to make it last as long as I can while I have an engine built but its getting worse and its just a matter of time before it completely lets go. Good luck to you.

no he means ignition timing controller. the Apexi ITC is one example I believe that Split second makes a similar product.

you can blow your engine even with a PEMS.. but the more protective gismos that you have tuned the RIGHT way the less chance you have of doing so

Build up the bottom end and put a PEMS unit in and go for conservative boost/hp levels and you will have a much more reliable car on you hands. Do it wrong, like I did, and you will have a money pit on your hands.

You don't have to, but I would recommend it. After blowing up my motor and seeing what it costs to rebuild it; I would never want to see someone else go through it. If you can afford to take the proper precautions ahead of time, the better off you will be later on. Wouldn't it be nice to stomp on the accelerator and not worry about the motor flying into pieces...?

Is this True?

"The 4EAT tranny (auto) can handle more boost than the 5-speed manual. The manual can only handle up to 5 psi (5psi then change clutch: 10psi then change tranny/to Larry's Chalek dog gears), but I don't actually know how much more the 4EAT can handle over the manual. I'm just waiting for Templar's supercharger to come through. *fingers crossed*"

So how do I go about to add a turbo if the 2.5 RS Short block wont fit on the 2.2L engine? finding another used 2.2 engine is not going to help... just the same thing..

all of the EJ engines are the same physical size... they just have different bore and stroke but the outter shell of them is the same.

the only thing that is different sometimes is the heads. I do believe that the DOHC heads had a slightly different exhaust port design but eveything should bolt up fine.

So when I'am ready... I just get the stage 3 short block from Cobb tuneing.. and it should bolt up fine.. but the exaust ports might be a little differnt so just get exaust ports that fit the 2.5 RS motor then right? If the person said.. If you want to add a turbo.. Make sure it's done right first.
