Change of plans and nothing to do = YES they are the same, all the measurements you gave in the pic and the port sizes you gave earlier. So... looks like anyone could turbo a 2.7 with these manifolds if they wanted.

I skipped reading the entire thread because I don't have the time. But I will give you as much knowledge as I have about the c20t and the c27a.

#1: The external dimensions of the motors are the same. This means that the c20t turbo, intake manifold and exhaust manifolds will bolt right up.

#2: Gabe was not sure of this but I am 100% positive on this since I had a c20t sitting in my garage at one point. The Winged turbo on the c20t used three wings inside the turbo to control boost pressure at different RPMs. One was Vacuum controlled. The other two were controlled by the ECU.

#3: YES, you will need a standalone ECU in order to keep the engine from inevitably killing itself and to control the boost pressure and wing angles. Now wing angles can be tricky if you don't know what you are doing.

Why do you need a stand alone ecu to run it when you can run the factory turbo ecu. If i remember I was talking about running a stand alone for when i build a custom 2.7 turbo and that won't be using a wing turbo

The C20t ECU would not have the correct fuel trim for the added displacement of the C27a. This would cause a consistant lean condition. This would not be a good thing with forced induction.

Thats ok as I will be running the c20at In my car while i build a c27a into a turbo as i will probably have trouble attaining the parts and i am only building it as the funds become abailable so it will take a while to build. At the moment i will run the c20at with the original computer. I purchased a 2.7 factory turbo but when it gets here it will be 2.0 not 2.7. when i get the 2nd motor built i will probably run a stand alone or at least a piggyback computer to keep things in check

Well the turbo motor will be here soon it will be in customs on the weekend. Pity the shiping company put it in someone elses container so now it looks like its gonna cost me another 400 to get it here, plus i have to go to the port to pick it up when it was originally ment to be shiped to my door

I called http://forcedairtech.com/turbokits_legend.html back in December and they said that they would be discontinuing there turbo setup after the first of the year. I asked if he could give me the blue prints or mail the setup and he said no because the form fit the piping to every car. You may get luck y and ask for the ecu they used this is what they used Vortech RRFPR, Split Second TMC

Yeh I have contacted the seller and im wating for him to contact the shiping company. If i have to pay it it makes it expensive, I should have gone straight to making a 2.7 turbo but i have to pay it if the seller wont cos i cant just say no i dont want it now

Have you already paid for it?
Is it already on it's way?
If they are going to charge you more than described in the original transaction you have every right to back out.

So you've already paid the extra $400 for "shipping"? That sucks. Get in contact with the seller or file against them.

Ok guys, ya know I had to get n on this. Here's some of my turbo progress. The turbo is mounting right under the front passenger floorboard, inline with the exhaust. The floorboard there was cut out, raised a couple inches, and welded back in to make room for the turbocharger. From there, the charge air goes straight up to an in-car air-to-water intercooler. (Water in the intercooler is cooled under normal driving by a separate radiator at the front, but for racing application, we're just gonna put icewater in the intercooler reservoir.) From the intercooler (which is taking up the space the heater box and ducts used to be) the now-cooled charge air goes straight through the firewall towards the TB. This is all being done with the 2.7 litre, which has proved to be tougher than the 2.0 turbo V6 on our dyno runs. We came to this conclusion when the 2.0 threw a rod when we tested 12 lbs. of boost. The 2.7 ran well with 15psi! Original internal components on both of these tests. No modifications were made to change compression, and a/f ratios had to be constantly adjusted manually during the tests, indicating an aftermarket stand-alone engine management is absolutely necesary. With any load on a boosted c27 with the factory computer, and you'll melt a piston from lean temperature before you know it. Don't write me wanting pictures. As much as I'd like to show off, I have a private sponsor who wants nothing to be seen until the car debut. This is hopefully going to be at the Legend meet in July. Hope to meet you guys there. I hope these ideas help some other cars break 300hp. That's our goal, and when we're done, and the car is shown off, I will be fabricating a few hardware kits to do this install on your Legend with minimal farication for the installer. Let me know if there is some interest in this. All piping will be stainless, and with the remote mount of the turbo, you won't need special headers. I'll try to include all extra stuff, too, like the external oil pump for the turbo, the radiator, hoses, and a midgrade engine management kit. Pricing of the kit I estimate about $3000. If it sounds like something ya'll REALLY want, let me know.
