Newbie Engine Q's
Wednesday, September 13, 2006 8:36 PM
It's been a while, but I'm ready to take the next step funds wise...information is where its lacking. I've been researching 2200 engine modifications on the org and asking around local machine shops for pricing for quite a while now. But there are certain things I cannot find no matter how hard I've looked through the posts on here.

So far the parts bin has proform narrow body self guided 1.6 rockers, arp head studs, replacement head gasket, stock pushrods with less miles from the donor engine, stainless 1mm+ valves and a headache. Crane cams has been very helpful in choosing a regrind to stay within the limits of the stock springs/retainers as well, but don't have that just yet.

I've asked around local shops for pricing a 'single' head p&p overbore and 3 angle valve job, it could range anywhere from $50 (crappy) to $500 which puts it in the range of a patriot performance prebuilt head. No response yet from patriot on whether the 2.2 OHV head is for 1998-2002 2.2L or if its the earlier 2.2 engine, or if they do both.

The thing that confuses me, and I know I'll seem like an idiot, is Patriot Performance mentions "stock oem valvetrain" and a "3.53 bore". Mating a bored head to a stock engine block and pistons wouldn't create a slight problem? For some reason I have it in my head that you had to have the piston bore matched to the head, so you don't get a lip at the top of the combustion chamber. In that case you would need to bore the piston chamber and get oversized pistons & rings to match. Or is the 3.53 bore referring to something else. It's late, and I've been working since 7am so excuse the stupidity, atleast its in the right forum.

I guess its more of a where's MadJack type of post hehe. You always learn something new.

no engine gurus around? I just want to know if you can slap a ported and bored head on a stock block without having to do any modifications and still get worthwhile engine response.

Sorry.. We're not on the org 24/7.
No cylinder heads do not have to be 'matched' to the bore. the piston does not go into the head, it stops even with the cylinder.
The earlier 2.2 is also called the 2200, it's generally the same engine with very minor modifications.

If you're going to pimp your engine, you might want to just spring for a 2.4L swap (or the eco). They produce much more horsepower stock, have way more mods available, and are generally much stronger (and thus more capabale of producing more HP).

Just the info i was looking for, thanks. All the heads I've had experience with before had part of the piston chamber extended into the head, which I found out after bugging a few shop veterans is called quench style. I was in a rush to get things done this weekend since the weather was so nice, but instead ended up working..feels wasted.

I've had good reliability with this engine, and am not looking for much beyond 200hp. Some minor head work, cam and few internals paired with 5-8 psi should be more reliable then pumping 10-15psi into a crappy flowing head. Atleast thats my reasoning.

Sounds OK to me. Just remember the 2200 is only about 115 HP (on it's best day), so 200 is damn near double stock.
