Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Twin Turbo?

Oil feed & return lines are pretty easy... The exhaust & intake plumbing on a TT setup would be the real problem.

One question:

If you remove the battery and toss it in the trunk (and whatever else you can take out), wouldn't a single turbo not only fit easier, but be easier to work with all the exhaust plumbing? Or are the Turbos in a TT that much smaller that it would fit with no problems?

And I saw a few years back a conversion for a Mitsubishi Diamante Wagon that had a Twin-Turbo kit from the 3000GT VR-4 dropped in it. The one interesting thing you can tell of right away was the nearly 2 foot long by 8 inch wide rectanglular hole in the front left corner of the hood (looking at it) which was the cool-air intake for the turbos (Probably the intercooler of course). Was a very slick project car.

$15,000 in man working hours maybe. But, I cant believe that it would take this much money to produce a working TT setup.

To produce and make profit on something like that, $15,000 is high, but it doesn't surprise me.

I know lots of people that have dumped TT setups for a single turbo.

Several Supras come to mind first. They are always a ton faster... Imagine that.. Better efficiency = better power; every time...

I ran a 20G turbo on my Conquest (among others - 12A, 14G, 16G, T3/4) and never had boost lag problems. The only time it showed lag was below 2900rpm. I don't even cruise below 3k... Exhaust setup can greatly reduce lag by itself (as shown by my Conquest's 3" single piping) and the newer turbos with VVT are even better!

what about a sequential turbo setup??

That is great i was think the same thing. about the T-25s. i just got doen reading another ardical on turbos from the sport compact car of september. it said that a TT set up on V6 CAN be better the a big single. Cheap is the idea here. i want to see just about how much i can get out off 1500. which is now down to 800.(3.0L) tools is no problem either. like i have said befor my father has been a autorepair man for about 30 years. I also have a 4 car shed that will work out nicely. if you guys want to come help sweet. i am kinda out in the boonys thou. like 5 miles downa dirt road.(SUCKS BIG TIME) when this idea started it was goign to be justy a few things here and there. now a sweet ass motor is all i care about. where abouts would i find this nice little cheap T-25s??? i need to buy this here and there so mom does not yell at me.

I'm sorry...but if anyone thinks they can make more power and have better efficiency, for cheaper doing a twin set up on the contour or cougar, over a single set up...go ahead. I've done plenty of research on the KLO3 series 2.5L V6...and in all cases it was easier and cheaper to make a single turbo setup, and produce more power, and be much more efficient. And lag was still minimal.

Porsche is not Ford...and Porsche uses a much different type of setup for their turbos than other companies. To reduce lag they actually use the idle exgaust to spin the turbines. A very cool concept.

I may have made a broad statement, but From the research o've seen, even from ford engineers I know, they recommend a single turbo kit. These are ford engineers, noit techs who work in a ford dealer.

Sorry if I offend anyone, but as I said earlier...go talk to the Supra guys...ask them about the 1000hp cars, and howe many turbos they have. You don;t need 2, when 1 will be more than good enough, and better. Yes Sequential turbo setup is cool, but that'd be tough to fit too.

But hey...it your money everyone...so if you can afford it, get a custom twin setup made, I'd love to see it, since it's a very cool thing to look at.

Also different engine architecture. Flat-6 Like 2 I-3's sharing crank.

im not an expert but my friend with a gn has one gn doing 9s. then he did a whole new setup. now he has a twin turbo gn. he did a 8.xx in the 1/4 and should be breaking into the 7s within the next couple weeks of tuning and wat not... i have a couple other friends with twin turbo v8s and they are doing 9s and daily drivers. i heard both that either on or the other is better... i wouldnt mind seeing 1 or 2 on a contour...
