I guess I'll jump in at this point.
My name is Eric. I'm a Probe guy. I'm one of two (you know the other) moderators for the 2.0 forums on Probetalk. I've been reading over here for some time now.
The FSZE is not a Probe engine, I'm not quite sure what was meant by that comment. Most often I've seen the FSZEs on US soil come from Capellas.
Unfortunately, for us the FSZE doesn't swap without a large amount fo difficulty. At this time there is only one person I can speak of that claims to have it up and running. One person even swapped it, then swapped it back a few months later just because he couldn't get it to run correctly.
The main problem comes with the intake manifold, as we have nothing to control it. Though we've discussed how it might be possible extensively.
The current trend with us seems to be turbocharging, as there are quite a few guys building up home kits or buying kits ready to install.
If you guys want to, there is a good deal of information in the 2.0 Performance Forum on ProbeTalk. Just use the search option to find it. I'm sure we're due some discussion on the subject. Unfortunately we lost some good information a while ago when we switched board formats, but there's still a good deal there.
In terms of acting immature: It's a message board. It's no different than any other. The moderators work hard to keep that type of stuff out of the technical and performance forums. The only major differences may be that we have a pretty good and experienced staff and a lot of members.
In my personal opinion of the motor, I would have to agree with LinuxRacr. I don't believe that the difference will be all that significant and the engine itself could be a dead end. It may not be in good condidtion obviously, but I believe it would be rather hard (read: expensive) to get more power out of it. Should that level of power be your ultimate goal, then by all means go for it. It just seems to be quite an expensive option for the trouble it might cause.
Turbocharging it is not a great option. For more N/A power the heads would need to be worked (pretty extensively). Cams could be ground as the ones in the FSZE are still rather mild and based on economy. Nitrous Oxide injection could be viable, but again, the engine may not be in good shape.
My outlook would be that for the price of the engine, I could buy forged pistons and connecting rods and be well on my way to readying the motor for turbo (another 3-4 grand with a lot of potential for power) or a natrually aspirated monster (another 2-3 grand for headwork and tuning to round things off).
(I usually lose sight of my point when I write long winded posts like this, so I hope most of these things (mostly opinions granted) make sense.)
Thanks guys,
Eric
