Twin Turbo custom Kit on a 2.2 or 2.5L?? possible in reality

[xtrempickup]

I know I heard that a twin turbo on a 2.2L doesnt really show any gains at all but I was thinking if it would work this way....I was wondering about mounting them vertically on a 2.2L. I was wondering about a Twin turbo Kit, have a custom exhaust manifold(2 ports for turbos, one for each 2 cylinders) made that could support two turbos. I was thinking if a small mitsubishi could be run on the exhaust from 2 cylinders on a well built up top and bottom end motor that was pushing 150HP+ before the turbos. That way two turbos could use two each and i guess a custom swingvalve adapter could me made to combine them into one opening to mount to the exhaust system, or could run a true dual exhaust. I think only real pain would be cutting firewall and making it all fit behind the motor and getting the oil to and from the turbos well.

I think the engine is just too small for two turbos...even two Mitsu turbos.

I would think so too, But im thinking only trying to run a mayb 7Lbs on each turbo and that way also extending turbo life and i was thinking on a motor built to run say 200HP with all the porting and work done, I think it could potentially be done and would work if someone had a lot of time and knew enough. i guess i would have to take into a ccount needing either one really good intercooler or custom run 2 along side the radiator, one on each side. Question im wondering most is if exhaust from 2 cyl could drive the turbos at 3000RPM or would there be soo much lag or no boost at all. I guess NOS wet system could be used to get the power up soon but anyone think it is a possibilty of working out, then if it does, up the boost to like 9 on each turbo or more.

2 cylinders wouldn't be enough to spin the turbo, I would not think. the lag time would be unbearable

hahahahaha

I see neither of you two know of or remember The twin mitsu turbo shadow of a fellow board member's. I suppose on the verge of 11's in full street trim on street tires doesn't constitute any notable gains for a twin turbo setup. LOL

You guy's should do a little research before knowing what your talking about

[xtrempickup]

I only read a thread about a week ago that said there was not enough noticeable gains to warrant making a twin turbo kit, i think it was in this forum also. I m only repeating what i saw, not what i believe , i think it could work. thats why im asking these questions and going about asking to make it in this configuration. I think the thread was called Twin Kit and it was in the engine forum.

Why use parallel turbos, if it he want's to install 2, go serial.
A tiny one for low end, and then one huge mofo for high rpms.

[xtrempickup]

never thooght about it, i thought it wouild be easier to set it up parallel. I dunno any suggestions would be good

[igotaneed4speed]

i dont knwo what car it was but there;s a reference about a twin turbo 140 cubic inch twin turbo 4 cyclinder running a mid 7 second pass in hot rod the new issue... its in the article about allowing turbos in the ihra and nhra for pro mod....


so with the 2.2 being 135 cubic inches i dont see why it wouldnt work ... ill try and find out what car they were talking about and post sum links and info

Be nice to Pete, it's ok that he doesnt know what the hell he's talking about. lol Just kidding dude.

Two mitsus. would definately work, but you must take into account of all the fabrication of the support brackets and oil and coolant lines, I dunno how you would supply oil or coolant for another item needing those... Would you need an additional Hex, water jacket, etc.?

I say go for it though. If you've got the money, spend it.

[xtrempickup]

cool sounds like my next major project and i defiantely would wna go it with a 8V. not sure but surely a 2 piece early TII intake system and then figuring out how to fit everything and all the fabrication to and from the turbo to block and coolant systems. I guess it takes a lot of planning and im gonna get a junkyard block thats probably gonna be a Commonblock to do this to. Im guessing this would be for my 84 Laser(CS Daytona Clone.) when it gets moving i'll keep everyone updated and im sure if i go it it wont be til spring since i dont have a garage to work in for the winter

If what you are contemplating is a track only proposition, then anything is possible. Building something to be fun to drive on the street is an entirely different undertaking. I've personally spoken to a Chrysler engineer on the possibility of running twins on a 2.2 or 2.5, and he told me there is nothing to gain by doing so on such a small motor. He basically told me that twins can't do anything on these little motors that a properly sized single turbo couldn't.
As far as that Shadow is concerned, that's only one car, and it's certainly not the quickest turbo dodge in the U.S. There are quite a few single turbo TDs more powerful than that car. Look at Larry's Spirit R/T for instance--500 plus whp. If you have alot of money to play with and want to be different, by all means--go for it. If, however, making big power is your goal, your money would be better spent elsewhere. There are alot of very bright TD guys out here, some of whom don't mind spending thousands of dollars for power. I've got to believe there would be more of these cars with twin turbos if that were the hot ticket.

And I used a winking smilie

[xrattiracer]

as noted in the other thread, the only reason to do this would be to save money over buying a single properly sized turbo. and this is only possible if you have the equipment and know-how to fabricate the components for cheap or free.
