Default Does anybody have dyno plots for a Stroked 2.0L and a Factory 2.2L?

I'm looking for dyno plots of a Stroked (to 2.2L) 2.0L and a Factory 2.2L. If you have them, please post them, and if they're too large, let me know and I'll provide you with an email addy to send them to.

thanks

I have been looking around these forums for a while and one thing there seems to be a lack of is discussions about engine internals. Since there are lots of discussions about transmissions, I am a little supprised.

So here are my questions:

Apparently you can get a 2.5L block. The only place I have bound one is Cobb and its at least 5k for the short block. When I was doing Datsun 240/280z stuff, you there were lots of variations that people did using various available Datsun cranks that were available from junkyards. Say 240 crank, or 280 crank or you could get a 3 liter diesel crank from an old diesel Maxima. Of course you had to have the right rods and pistons, but you could pick up a lot of stuff from junkyards or old cars, take em to a machine shop, have everything cleaned, magnafluxed, reground etc and end up with larger displacements. If you were willing to do the dirty work, assembly, disassembly you could get a nice stroker engine ready to turbo a for a lot less than 3k.

So, can you do things like this with Imprezas? For instance, if I could pick up a long block, 2.5l from a junk yard, order new pistons, and cam shafts, have the head and block/crank re-built and blue printed and assembled at home in my garage, I would like to do this. But I am not going to pay approximatley 10K for a long block.

Another thing I noticed is that there are only a few places that have cam shafts and the cost here appears to be real high too.

Anyone built a stroker ready to drop in to replace the 2 liter in the 2002+ WRX (I mean s streetable car here) and done it for a reasonable amount?

Also, why do people go to 2.2 (at least for drag racing) and not up to 2.5. I know there are limits in rally racing that allow no more than 2.2 but in drag racing?

Well.....

There has been some discussion about engine internals here, but not recently. The reality of it is that very, very few wrx owners have needed to rebuild just yet. The stock short block is good to about 425 hp.

The guys with RS-T's (aftermarket forced induction) have much more experience with engine rebuilds.

You're right about interchangeablity. All EJ series motors are basically compatable. You can take a closed deck legacy turbo block (ej22-t) and put a stock ej25 crank in it, with some custom rods and pistons in it. You'll have a very nice 2.4L motor, if you sort out the details right. The eg33 (svx) motor is also somehat compatable.

I would suggest searching back on these forums for more info.

The one thing that is really missing is the details of what it takes to actually build a good motor.

Cams are expensive because there are four of them.

Try searching on PLAYER (he's Aussie and damn knowledgeable about building out our engines) and "stroker" and I think you'll find the link he told me what to use to build a 2.4 liter from spare parts.

When "stroking" an engine, you may not get as much performance as you expected - the piston has to travel further and this can take time so the engine doesn't spin as fast. I know in Aussie land most of the guys only stroke to 2.2 liters not 2.4 or 2.5.

good luck.
