Default N/A setup with a 2.2L block and 1.8L heads (reliability questions)

hey all,

I recantly grabed a 2.2L block out of a 92 Leggy for cheap, it's in awsome shape, but rather than finding some 2.2L heads, I was thinking of using my 1.8L setup with the bigger block. A bunch of questions I have though

1. reliability...I realize that this setup bumps the compression up to about 11.5 to one, how reliable is this setup? I don't really want to blow anything up.

2. I plan on running 93 octain only in it, does anyone have any spark plug sugjestions to help it run smothly?

3. what do people sugjest I use for a head gasket. A friend of mine recomended a wider gasket to lower the compression slightly.

4. I do plan on using a piggy back EM of some sort soon on the car, when I do, has anyone tuned one of these? should I hold the timing in or advance it out? would it be more reliable if I let it run a little ritch?

5. how much power do you expect I'd be running out of this setup? I know a regulare 2.2L is around 130-135, with higher compression would I be seeing more power?

thanks guys,

-Ben

I'm guessing that the money you are gonna spend on engine management capable of timing and fuel changes, associated quirks and the limited power the setup will make is probably not worth it.

I'm not sure how big your budget is, but you can also pick up 2.5's for around $500. You can do the entire swap, including some maintenance and new clutch for under 1 grand. No real tuning issues involved, and you will have around 160 hp.

Its hard to express how much I agree with this statement. If you're looking for a bunch more power, this is the easier way to go.

If, howerver, you are stubborn like me and like to try new things just for the sake of trying them, I would recommend the Greddy Emanage Ultimate. I am currently running the EMU on my turbo'd EJ22 (previously NA) and the more I tune with it the better I like it. The problem I encountered was that there are too few people using the EMU and I had to call Greddy a bunch to help me figure a few things out. Your benefit is that you have people like me around that can help you figure things out that may be hanging you up. The EMU adjusts timing automatically btw.

As far as your block/head combo you might want to send a PM to reddevil. I swear that guy has tried just about every block/head combo imaginable at one time or another.

I love the fact that no one actually answers ppls questions they just tell you what's right to them. I'm not the most knowledgable persons to talk to about engine builds but I am trying to do the 2.2 block with 1.8 conversion. And would like someone to actually answer the question about reliability and horsepower specs would be amazing! I have all the parts laying around. So I'm doing it. It would just be cool if someone had an answer for me and this guy lol
