more hp from a 2.2 liter?

blanchmann · 02-22-2006, 07:30 PM

looking to maximize hp without putting additional strain on old motor. It already has SS Exhausts. Will a K & N filter or anything like it make a difference. thanks in advance.

Check the compression and do a leakdown to ascertain the condition of the engine.
If all is well install a K&N and enjoy.
If not do a top end. Then enjoy.
Good luck.

did the leakdown. came back at 9%. what kind of filter do u recommend?

2.7RACER · 02-22-2006, 08:14 PM

I like my K&N. Don't expect a big blast of power.
Your 2.2 gets its power up on the rev band so helping it breath is the right thing to do.
Have fun,

Do a search. I remember a thread (I may even have it downloaded somewhere)
Had dyno charts of a 2.2 E with stock air box/K+N's
Stock was the winner.

blanchmann;
What's the current spec of your motor? T/E/S? Carbs or MFI? Where do you do most of your driving?

blanchmann · 02-23-2006, 06:34 AM

1971 911t 2.2 zenith carbs. most driving done around town (non-freeway)

To be honest, to make more HP from that spec motor will require swapping parts. Since you spend most of your time in "local" driving, the T spec engine is almost the best option and outpulls the 2.2 E's and S's up to 3000 RPM. The cheapest way to maximize usable HP without putting a strain on the old engine would be to swap it out for a nice 3.0 longblock. With a little bit of fiddling you could swap your carbs onto the 3.0 along with your SS exhausts. It should give you all the performance that you'll want for less then dicking around with a ground-up rebuild of the motor.

Getting more out of a 2.2t... the K&N filters, freer flowing exhaust... Upgrade the ignition... the stock CDI is alright, but an MSD unit might squeeze a few more horses out of it... it should definitely start easier, and idle better.

To get considerably more out of it, you'd likely have to rebuild with E or S spec pistons, cylinders and cams.

Check out this thread (pelican) ; 2.2 E stoker HP with graphs

John, what thread? You forgot the linkeroo!

JCF · 02-23-2006, 01:06 PM

Can't seem to be able to do that.
That is the title of the thread ( 2.2 E etc. )
Type that into the search engine and it should come up.

2.2 E stroker HP output

That one. Gotta spell 'stroker' right, and you'll find it

JCF · 02-23-2006, 01:22 PM

Pelican Parts Technical BBS - 2.2 stroker HP output

That prob won't work . Search didn't.

Just saw the link there Matt.
I guess I'm just TOTALY illiterate.
Thanks ;

FrayAdjacent911 · 02-23-2006, 01:40 PM

S'alright John.

Looks like he had a 2.2l E spec, and replaced the crank and rods with ones out of a 2.4 to increase the stroke, and got decent gains from doing it. Doesn't sound too difficult to do.

I'm probably at least a year away from rebuilding my engine, if not more, but I'll be looking to get more out of it... might just try to get it to 2.2l E spec. It pulls pretty good as is, and I'm not going to track the car, it's just a fun driver.

JCF · 02-23-2006, 04:02 PM

Re reading the thread I think that isn't the one I was thinking of - There is another one - same engine maybe but a graph of the orig set up before the rebuild run with the stock/the K+N's and naked.
I'll keep digging.
It is interesting to see.

I gotta ask...... Is it wrong to reply to someones question when you appear to know absolutely nothing about the subject ? Is it right that this guy should go by someones novice advise and buy a K&N filter and make no extra power . And at the same time degrade the quality of air the engine breaths ?
Is it right that this guy might go out and by headers or something other that will not only downgrade the heater operation but also cause a loss of low end power (the only place the T engine performs btw) . Remember that Porsche used the same exchangers(headers) on the 73` R/S as this guys 130hp T engine. Im more than sure his exhaust is up to the task in hand.
Lastly how about an upgrade on the ignition ? Well lets see. The car came with CDI from the factory. It obviously works and it provides far more spark energy than a low compression , mild cam engine could possibly ask for.

So at this point this poor fella will have spent over $1300.00 . He would have broken at least 3 exhaust studs , hacked his factory ignition harness . Possibly spent a full day figuring why there is no spark. Etc etc.
And worse yet maybe advance his timing into the danger zone or screw up the carb adjustments while wondering .... Ummm I think I did something wrong. The car feels even slower now Let me try adjusting this.

So in the end thanks to some of the above posted "experienced" advise this guy has ,

Lost some bottom end power,
has less or no heat at all,
allows more elements into his engine with a free flowing filter,
pockets are $1300 poorer,
and worst of all after 10-20 hrs of tooling and broken knuckles etc hates his car and thinks he screwed up .

Please someone tell me if im out line bringing this up. It seems to be routine around here that poor advise is handed out when in fact if you dont know you should not type ! And guys, those of you who did offer foul advise I realize you are only trying to help or join the post but... It doesnt help .

I did see one good responce above .... Get a 3.0 longblock .

My opinion ? Have your carbs balanced , timing checked (at 5000 rpm), adjust your valve clearances, and best of all remove unessasary weight out of the car. Other than that your 2.2t is at the end of the power quest without spending huge $$$.

Well, Kurt, I'm not Grady, so I just shouldn't participate in technical discussion then, I guess?

Maybe my firsthand experience with taking a CDI fired engine, transplanting into another car, then installing an aftermarket ignition, and feeling the improvements just isn't worth a damn.

I know I'm pretty new to p-car ownership, tinkering and wrenching, but I've learned and applied a lot of stuff. Reading and participating in discussions like this is how I have learned and continue to learn about my favorite old car. If I'm wrong about something, I surely welcome corrections, but would greatly prefer it in a constructive manner.

I haven't MADE anyone go out and blow their money, nor has anyone else here. I've given my opinions, based on my technical knowledge, however limited, and posted it in a DISCUSSION. No one is making anyone take MY advice or suggestions. I also don't see anything wrong with trying to get more out of what you've ALREADY got.

Again,we're discussing here. Feel free to DISCUSS how my, and other people's suggestions might not be in the best interest of the original poster, but please, don't $hit on us.

pjv911 · pjv911's Garage

Matt , I didnt mean to $hit on anyone . I guess this responce was just a buildup from many previous threads. Didnt mean to offend. But the facts still remain. Some of these new guys need correct info because they are lost . It would be a shame if this guy above listened to anything posted here. I dont see how it could be considered ok . And No im not Grady either but this wasnt a hard question to answer.
