turbo

can u twin turbo a 2.2

Anything's possible but because the turbo's are in the back of the car it will make it a bit more difficult. It has been done before though, I've seen it done with 2 mitsu turbo's, and another with 1 mitsu 1 garrett to get some low end grunt but still have top end power.

What year? I dont think i would do it b/c you can blow your head.

How would you ''blow the head'' just because it's TT?

No, there is only so much pressure you engine head can handle. Alot of stock cars that have a turbo only may put out 4-10lbs of boost. If you want to dubble this, make sure you have dish pistons, better rockers, and head reinforsments.(sp) Do what you want, you don't have to listen to me. Put 20+lbs of boost, let me know what happens. Good luck and god speed!

LOL. Read my signature buddy. I run 22 PSI boost, still using the stock style headgasket and bolts. The head has been ported, nothing else. And who says you have to run big boost with twins anyway? You can run 10 PSI if you want. The stock pistons are dished, turbo engines run 8.1:1 compression. And rockers? WTF I've seen 400 WHP turbo dodges that run the stock roller rockers at 30 PSI boost.

FYI I've seen 34 PSI boost run on these engines, nothing happened to the head. The engine had head studs, and used a completely stock head not even porting. What exactly are you thinking happens to the head? The only thing that hurts it is detonation, I've seen that melt a combustion chamber. But boost alone does not affect anything if you have the fuel and octane to go with it. Like I said, 34 PSI boost I've seen on an UNTOUCHED head with a 50 trim T04E hybrid with .63 turbine stage 3 wheel. The engine made 334 WHP, quite impressive for a stock 8 valve head.

How have you SEEN 22lbs of boost? I have seen it to, but the engine ws junk after 2K miles. I have seen worped heads, cracked blocks all sort of things. you MAY have seen it, but look at what happens down the road. Its like running NOS all the time, but years down the road, the engine is no good. Now i am not saying NOS is bad, but you dont want to hit it all the time when you see a stupid ricer. OK BUDDY?

I said I've SEEN 34 PSI boost run on these engines before on the dyno with nothing bad happen, it was on race gas of course but nothing blew up. It's all in the tuning.
I personally run 22-25 PSI boost EVERYDAY. So far my engine is fine with 15K on it, so there goes that theory. Compression test shows all is well, and if my head was warped I would have blown a headgasket a long time ago. And if my block cracked I'd be loosing compression or coolant would be disappearing.
Who is telling you all this information??? Do you even own a turbo car? Try going to the turbododge forums to the hundreds of people that run 18+ pounds of boost on daily drivers and go ahead and tell them that their engines are gonna ''blow the head'' soon. LOL, this is starting to get funny.

Oh yeah BTW I know a few people that do run NOS everyday, just a small 50 shot. Some guys have 50K on their engines that you say won't last 2. Oh and they also all run over 20 PSI boost in combination with the NOS. The head didn't blow. LOL

You are obviously not familiar with the 2.2 engine whatsoever, or any turbo engine for that matter. Some versions run 12 PSI from the factory. And mopar performance also sells a kit known as the super 60 package thats meant to run 18 PSI. If Mopar sells a kit for it, it's sure to be safe. The kit consists of a different turbo, ECU, injectors, and MAP sensor. Nothing about the engine itself needs changed because these engines can handle a lot of boost straight from the factory.
Now if we were turbo'ing a honda here that already had 10:1 compression, I'd say yeah I wouldn't run more than 8-10 PSI boost. But the 2.2 comes with 8.1:1 compression from the factory, you can easily run 20 PSI boost on it with no ill results as long as you have fuel upgrades and 93 octane.

Hmm, no response huh? Yeah thats what I thought.
Hey look up the user RATTLESNAKE on www.turbo-mopar.com and check out his 2.5L running 36 PSI. A 2.5 is the same thing as a 2.2 but with a longer stroke. He didn't ''blow the head''.

Here I'll make it real easy to see a bunch of setups, mostly running more than 20 PSI.

WAIT!!!!!22-25psi? You chang this al the time. No responce??? Hmmm just like you, i work and have a life. I work on cars on the side. I known about turbos a long time time. I have see what can hapen when you put aftermarket turbos on a non turbo car. I seen them blow heads and have other problems down the road. you may or may not have seen them. I bet you have thought since you do this all the time. I usuall spend my time making drugs and taking care of pt. in the e.r. for a job. I am not saying your complety right or wrong. I know my stuff as well. I do have a few ase. cert. but that does not mean i know everything. I will tell you what i say to other MD's, do what you think is right. If your wrong, we will take it one step at a time. OK? gtg?

How did it change? I said 22 all along....are you talking about now I said 22-25? 22 PSI is what I run as a daily driver on the street. 25 is what I run at the strip, sorry I didn't clarify earlier.
Turbo'ing a non-turbo car and adding twins to a factory turbo car is 2 WAY different worlds. Either way, I'm still not even sure what you mean when you say ''blow the head''. You would blow the head gasket well before damaging anything on the head. It's all a matter of tuning and compression ratio that will determine how much boost you can run. Like I said my compression was about 7.6:1 which let me run such high boost on 93 octane pump gas with no issues. Would I do it on a converted turbo DSM? No way, probably 10-12 PSI max. Factory turbo DSM's can run 17 PSI on the stock turbo before the turbo overspins, swap on an aftermarket and I've seen 20 PSI on pump gas on the bone stock long block.

And when I said about no response....you responded within 1 day every other time I posted, this time it was over a week. I check my email everyday probably 3 times a day. I work 7:30-4 6 days a week.

No, there is only so much pressure you engine head can handle. Alot of stock cars that have a turbo only may put out 4-10lbs of boost.

These two statements contradict each other big time. You say you know a lot about turbo's and turbo cars. But look at what you posted earlier. I've never seen a factory turbo car without dished pistons, strike one. Upgraded rockers? Sorry I know 500 WHP engines running factory rockers from the 2.2 engine. Strike 2. And head re-inforcements, well all I can say is I ran a factory gasket and factory bolts on 22-25 PSI and 300 WHP, so there goes that theory. Strike 3, you're out. Seems to me like you really know what you're talking about. :screwy:

WAIT! I still have not seen a stock car with a turbo with out dished pistions. ALL turbos come a dished piston! SO...CHECK 1 for me!!! ALSO...I have a friend that works for audi in Parma ohio, thoes cars have audis and that car does have a head reinforcements.Thats 2 for me now! About that strike three....lol...I would like to see your head on your car. I bet you it is leaking or the gasket looks like hell. I have people that work on cars for a living, seems like you dont. you may be running 22-25 psi or when you decide to change it, thats what you said before, but it sounds like a broke down want to be ricer. I have seen 3 turbos on cars before as well, but do you really think that engine will run for a long time?? NO!!!!! You car run 100psi for all i car, but lets see your cars engine last a long time. whenever you put mor stress on a cars engine, less time the engine will run right. the cars that come with a turbo or superchargers, the engine was built for it. None of this add on crap. SO.....you do what you want, run 22-25 or what ever psi you want, i will see you on the side of the road like i see other little ricers and as i go bye them, i just have a big smile on my face. Do what you want, dont let me stop you!

Holy crap, my whole point was that turbo engines come with dish pistons, you said earlier that the engine would NEED dished pistons. Somehow in your warped mind you twisted it around in your favor.
And what ''reinforcements'' do these audi's have? Please explain oh knowledgable one.
Sorry, 15K miles later on my engine boosting 22+ PSI and the compression test showed flawless results. No leakage here, and if my gasket looked like ''hell'' it would be leaking coolant into the oil. It's not doing that either.
How can stand there and say boosting 20+ PSI will make your engine not last 2K miles when first of all I have done it and hundreds of others have too? Did you not click on the link I posted awhile back? Tons of people on that forum are boosting 20+ PSI on daily drivers.
There were 2 times I broke down on the side of the road, one time I ran out of gas and the other was electrical issues that I figured out on the side of the road and got on my way. NOTHING to do with the engine EVER.
One more thing BTW. At about 8K miles I upgraded my turbo, you have to take the head off to do so since the turbo is in the back. The cylinders and pistons looked normal, head looked perfect, and the headgasket looked brand new. The only way a headgasket would look like ''hell'' is if it was blown, never done that so I guess I don't know what it looks like LOL. BTW, boost does NOT blow a gasket, detonation does. Detonation happens one of 2 ways, lack of octane or lack of fuel. There's turbocharging 101 for you.

ok...not a problem...you go with that! not a problem. take it easy, and good luck.Peace

Yeah, everytime I ask for REAL facts from you, you don't pony up. Truth is you have no idea what ''reinforcements'' you are talking about. And look back at what you wrote before, you stated that the engine needed dished pistons. And then you say all turbo engines come with dish pistons, but only after I tell you that.
Oh guess what, not all turbo engines come with dish pistons. I did that to fool you and see if you would play along like you have 2 other times and agree with me saying you already knew that. BS buddy, you don't know JACK $hit about turbo engine so STFU. I hope your bone stock slowass car blows the head because I know mine won't :grinno:
It's been fun making you look like a moron. :popcorn:

Oh yeah, damn how did you find all this time posting up twice in one night? You know, since you have a ''real'' job and stuff.
