Default '92 2.2 performance options?

I have the basics outlined, full exhust, intake, match port and pollish the block, free up intake, and I don't want move the power band up, I'm looking for mid range torque, but I havn't seen anyone who regrinds cams, and I'd like to stroke it to 2.5l, I might even build it for 91-93 octane fuel. I'm mostly looking for input and ideas right now.

You are thinking in the right direction, but need a little redirection.
Delta does a regrind for your cams. They run $165 plus freight. It gives you about 15 hp and it mostly a midrange torque grind. You won't lose your bottom end.

Unless you are doing the port work yourself, don't waste your money. There are minimal gains to be had there.

No point in stroking your block to 2.5l. What you want to do is find an EJ25 shortblock and just swap your heads and everything else over to it. This would put you in the 11.2:1 CR range or so. Along with those cams, you will break 200hp at the crank. We are currently building one of these in my garage. The engine is complete except we are waiting for the cams to be delivered. If they come today or tommorow it will be in the car and running by the end of the weekend.

For more, do a search in this forum for a thread about a high compression frankenstein build. Frankensubbies rule!

Thanks, do you know what grade fuel this will demand? I plan to pollish the insides myself, mostly looking to improve economy with performance, this is for a VW Vanagon, I love the engine in my SVX so much that I can't give up subaru engines and the VW engines are just too troublesome.

premium will be required. And unless you are doing a vavle job, don't really expect any noticeable results on your heads. It will kind of be like masturbating: no real product at the end of it...

Matt, this is awesome. I didn't know you were taking on a project like this. I KNOW you are going to get some dyno results right? I'm really looking forward to seeing how this turns out. I guess it's in the conversions section. This is something I may be interested in, in the far future for my Outback. It's turbocharge days are over. N/A would be cool though. I await your results.

BTW: The guys over at USMB.NET love Delta Cams. I haven't been as successful with my grind on my XT6 though since I ruined my exhaust by going to wide. The car has no low end now but top end has improved. I'm looking to purchase another set for my other XT6 that is setup for torque rather than hp. Sorry...I can't help talking about my oldy scoobies.

Has anyone else here purchased Delta cams for their 2.2s? What were the results?

BTW: NapaBavarian, you may be able to swap in a 2.5ltr SOHC ECU into your 2.2ltr Impreza. I used to run with a 1999 2.5ltr Legacy GT ECU for years and it freed up some hp. I tested 3 ECUs here in the past and posted the results. I swapped them on the dyno and kepted retesting, swapping and testing again. The Legacy one always came out a few hp/torque more than my stock ECU and another Impreza ECU. You can purchase a stock 2.5ltr ECU from junkyards, like http://www.car-part.com/. I purchased all my ECUs from junkyards there and get them anywhere from $25.00 to $65.00 (of course some are more). I do this because I'm poor and cheap.

I purchased Delta cams for my 1995 and 1997 2.2L cars
By butt dyno, it seems about 10-15 whp kicking in by 2500 rpm
Excellent bang for the buck

3 more questions...

1) will any ej25 do, or is it model specific?

2) will the 11.2:1 compresion engine run on 91 or will I need to mix in additives?

3) What computer are you using for your engine? Someone mentioned a later box, but I need to keep this OBD 1.

As long as you don't want ABS, supercharging is a very viable option.

I am currently pushing 6 psi, next step is 8-9 psi.

I am running it on a 1990 NA stock block (rebuilt with new pistons, nothing fancy).

If you are handy, it is VERY easy to do. But the cost starts at $750ish and up to $2000 for what I have spent to get where I am.

Here is most of the story.

For a legacy, the car is durned fast.
