can u twin turbo a 2.2

[PWMAN]

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.

[PWMAN]

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

[vamc]

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?

[PWMAN]

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

[PWMAN]

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.

[PWMAN]

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''.

[PWMAN]

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?

[PWMAN]

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.

[PWMAN]

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.

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.
