Adding a turbo
Seriously thinking about this now as my V6 really needs more oomph  .
I have a T3 Hybrid on loan (thanks Andygtt) and a plan ..... so far.
Plumb in T3 to a convenient point in the headers (where they meet 6:1) Oil & water feeds required. I hope to get away without an exhaust system
but might have to install a cherry bomb or similar if its too loud.
Install 2.5 Bar MAF in intake side and connect to ECU. (where can I find a suitable one?)
Fit intercooler or charge cooler?
Get it remapped
Any observations?

Yep, I just can't find the space to fit two like the Noble. I had to resite the alternator as things were tight, so the front turbo would
definitely foul it - or at least get it sooooo hot.
I think a single T3 on less than 10psi will give me the 300bhp I have always planned for. It might have a touch of lag but a hybrid spools up pretty
quickly I am told.

NOS is the way forward. Oh, and a supercharger, but that's all IMO, as I prefer superchargers. Are there any cams etc available for the 2.5? Do
the Jag VVC heads fit the 2.5 block?

How far from the ports is your 6 into 1 collector?

Si - I have explored the NOS route and was originally olanning to install a kit straight after SVA. However the running costs are pretty horrendous if
you intend to use the performance on a daily basis (and I do ) Then I looked at the Vortrex s/c but had to abandon that for space reasons - my
engine bay is quite snug and I would probably have to take the engine out to work out the fitting of the s/c - maybe a winter project or a future
build 
As for cams, there doesn'y seem to be much around for the V6. I can get a set of ST220 cam reground by Piper Cams which should give me a good
hike in top end power but the original cams are like hens teeth and so far I havent found any. The same applies to the Jag engine and I am not sure if
the heads are interchangable - nice thought though
worX - The collector is right behind the rear bank, approximately where Noble put their smaller twin turbo. The front bank will therefore have a
longer path to the turbo but I don't think it will be too laggy.
scutter - Just a tad out of my budget, but if I had seen that a year ago I might have sold a kidney to buy it.

Are you reducing your compression ratio or how are you going to resolve detonation?

The standard cr is around 10:1 so I am hoping that using low boost will prevent detonation. I have heard of people who use methanol / water injection
to good effect too.

10:1 is rather high for planned boost....
 
Compression ratio graph (A. Bell tuned induction book)
You might need to lower the CR....
Does the car have a knock sensor fitted? That'll give some protection (but only by retarding ignition and robbing huge amounts of potential
power).... Otherwise unless you're going to run on AVGas or fit the worlds most efficient intercooler (though powerboats get waterflow cooled
intercoolers more effective than 100% which considering the weather recently is a possibility) you're looking at potentially expensive
trouble....
Do Farraday engineering do a de-comp gasket for your engine????

Can't you lower the CR by adding a thicker gasket? Perhaps a double gasket would work, too?

That has been mentioned and I will cetainly look at that on the next inevitable rebuild. Meanwhile I use high octane fuel (100 iirc) so hopefully that
will keep Mr Detonation at bay but maybe my boost will have to be a bit lower than planned until then.
*edit* just looked up the spec and it has a 9.8:1 cr

Lowering the comp ratio isnt alwas the way forward when turboing as it throws up lots of other problems.
Making the engine breathe better is much more worthwhile when turboing.
Whats the VE of your engine at the moment?

tbh I havent got a clue what the VE of a V6 Duratec is. How do I calculate it?
Anyone?
