hight compression
Sunday, June 11, 2006 5:08 PM
ok I have a 2200 and was thinking about doing a all motor set up but well I'm not a real motor head so I need a little help I was thining about going the rought of high compression like a 11:1 or if it could be done12:1 a mild cam grind and head work I'm looking to make about 200-220hp at the wheels just kinda kicking it around cus I don't want nitrous or boost just all n/a

well 200 n/a with a 'mild' cam grind would be difficult to do. I think you'd need an aggressive cam grind, and say goodbye to drivability.

it can be done, but I'd suggest going with HPT or some sort of standalone unit that can handle the huge variants in vacuum pressure due to such a lobey cam. the stock computer may not be able to handle it so well.

also say goodbye to paying for regular gas at the pump, 93 or higher forsure without question

good luck

yea I'm just trying to see what I could do I would like to hit 200 but just going to see I should do so any input is great but what would you all advise to do to hit 200 so its not all that high of a number to hit and I know alot have gone well above that in the 2200

they have but its more easily attainable with boost.

good for you for not doing what everyone else is doing.

lots of work required to make 200, mostly old school tricks, etc that these old guys can help you out with

your not gonna hit 200 whp all motor out of a 2.2 without ALOT of money. Boost it or don't even try, especially if your gonna daily drive it.

You could get 200whp easily! Just keep an eye out on the 2200 power record thread going. you should be able to put down around of over that number with the same cost as boost, but alot of the work is going to be coming from machine shops and custom engine accesories. I'm currently talking to soem local SB pro shops around the Atl area about getting something working for the 2200 valvetrain, which will open up alot of doors for us. Stay tuned!


N2O + Bolt-ons = 220Hp/250Tq

cant wait it was that thread thats making me want to do it I just think that it would be wild to do it

it would be "wild to do" its rarely seen for 2 reasons, its alot work for small gains, and 2 nobody cares.... who brags about putting down 200 hp?

if you want to do it go for it, its nothing against you I'd just personally take a different route. Good luck either way

I would brag if I got 200 hp n/a out of a 2.2, but for sure if you want to go n/a, I would go with a 2.4 and bump the compression way up, like 12 to 1, 2.3 oil swap because you will deffinatly turn more rpms. Swap to the 2.3 HO head and beef up that valvetrain even more. Get everything balanced and lightened as muc as possible. Then deffinatly get HPT software to advance the @!#$ out of the timing(this is while running like 103 unleaded). I'm not so sure how the HPT sofware is with timing, but, you could always get the MSD unit. That could put you over 200. HAHA, I just read that, and realized...thats a lot of money.

yeah, take advice from guys with DOHC's, cause they know all there is to know about 'every' motor.

If you want 200hp from a 2.2 it would be "easy" to do. If you want 200whp, better take your time and use alot of money.


The cam doesn't need to be wild. You guys have rockers that can be easily changed.

well looks like I'm going to have to be going alot more looking into parts I'm thinking about doing this for the a bottom end so far was to get a comp cams grind new lighter rods and like a 12:1 piston and a .040 boar(sp?) and a lightened and balanced crank

At a 12:1 CR you better get used to the price of racing gas! You'll do better, if you plan on driving on the streets, with about a 10.5: CR. This would be with a good fuel and spark tune, with the HPT and a decent cooling system. 11:1 is possible, but you had better make sure you fuel and timing are right on the money.

The HPT is a must for the kind of rpms you would need to turn. You would need to move the rev limiter up to reach the needed rpms, let alone the fuel and spark curve needed.

The head is the biggest restriction on this motor, you would need a serious P&P, with oversize valves and a valve train to support the rpms you'll be turning. See one of the many 2.2L/2200 posts about our valve trains to get a better understanding on the work we're doing.

Remember that this motor has a long stroke to short rod ratio, which is more conducive to low to mid range torque than high rpm HP. This motor has about a 1.6: rod to stroke ratio. I'm looking into if it is possible to use a 5.7" rod, which will move the R-to-S ratio to 1.62:1. This won't be a big gain, but will help some.

Pistons, pins and rings will be an issue also. You'll need a good set of light weight custom forged pistons, with the friction fighting coating on the side skirts and some sealing good narrow rings. The coating on the piston skirts will allow for a tighter fitting piston and reduce the parasitic drag from the piston. Thermal piston crown coatings are still up in the air for street and endurance type motors, some have had problems flaking off. Light weight Spiro lock pins will be a must here. Look into a set of 1mm 1st and 2nd rings and a 3mm oil ring. These would have to be custom made also.

The cam will have to be at least a moderate to wild profile to reach these rpms You'd need the HPT to adjust the operating parameters of the PCM to run such a cam.

. You would also need to make sure you have a final drive in the range of 3.90-4.10:1 to reach the power band of the motor, otherwise it would just bog off the line.

It is truly possible to reach these power levels, but it will take allot of time, money and work to reach that level. I'm not trying to talk you out of it, just trying to let you know what your in for. If you're up to doing it, I'm all for it and will support you in any way I can. Good Luck!

^^^you forgot about the 94-oil pump!!! you always mention the pump!!!!!!
A serious p&p is right, it would have to be experimental, and there woult most-definately be some welding involved. I saw a old post yesterday with a guy who said he had a race port done, and had some good flow #s (after half an hour of searching ).

Hit the nail on the head.

lol, Yeah, you would definitely need that pump!





Re: hight compression
Monday, June 12, 2006 7:25 PM
well with the looks of it and the work that would be trouble it would be I'm now leaning to a turbo
I'm thinking that if I do a low compression and a good p&p as well as some over sized valves and a roller rocker set up I might just be better but then again I realy don't want anything that crazy if I hit 220whp I would be more than happy
