First post!
Just wandering if anyone on here has put a turbo (or even twin, but my knowledge or budget won't allow me to do that) on a 2.5 v6 Cougar?

Wanting to do this to my Cougar, here is what I think (single turbo config):
Turbo, exhaust manifold modification 6-2-1 and put the turbo at the 1 then run into the exhaust as per(?), oil feed lines, some nice 3-4" pipe to run the air from the turbo and from the turbo to the front of the car where a filter will be shoved on so it can breathe cool(er) air and lastly brackets to hold the turbo up so it doesn't have to try and float. Ooh and an intercooler so more pipe.

I'm pretty sure I also need:
Larger injectors, a better fuel pump (larger flow) and when I'm finished an ECU remap or something like?

Do I have to modify compression ratio and if so is there a pre-made head gasket? Only looking to run 8psi boost. Will I also have to get forged pistons upgraded crank etc?

Turbo - http://www.ebay.co.uk/itm/GT28-GT28..._CarParts_SM&hash=item3cc9986819#ht_763wt_904 taking oil from just off the oil filter with a restrictor(?) size I'm not yet sure of and having the return to as high up on the pan as possible(?).

BOV will be something I like the look of.

Won't be starting the project for a couple of months and its on a budget but I will spend money where I have too, these ebay turbo's have mixed reviews but for the saving I'm willing to give it a bang (and hope the engine doesn't!).
 
Yes a few have done what you have outlined in the USA with mixed results some have had turbos come off due to the low mounting others had engines go bang.


If you want to do it then get a zetec engined cougar much easier more reliable and cheaper.

If you do go ahead and do it to the V6 regardless of what you think it will be A)more expensive than you think B) almost certainly unreliable and C) disappointing as with the amount of boost you can safely run on a stock V6 it's barely worth the investment.

Oh and you can't twin turbo as they simply will not fit :)


Welcome to the club btw.

To correct one point, twin turbo will fit, this had been discussed around an engine that was sat on the deck. However, a single turbo, given where you'd have to mount it and run pipe work from/to is what creates the issues around unreliability etc. for the amount of money involved you could buy a 4 pot as a project car to turbo the poop out of and keep the V6 as a daily driver.
 
Ok I'll rephrase myself twin turbo won't fit without serious modification OR serious heat issues physical space is at a premium as it is, it's one thing discussing it over an engine very different to actually doing it for real and making it work.

Ack its always written to seem too easy.
I was planning on doing most if not all the fabrication myself but have since learned that MIG welding in such environments is not that appropriate and I'll be damned if I'm going to learn/buy into TIG.

Thanks for the welcomes!
unfortunately running two cars is not an option - insurance is a killer.
I'll stick with the 6pot stock :D
 
If you're after more oomph.....go down the 3.0L V6 (ST220) route. It has been done and is apparently pretty spritely :)
 
It's a nice dream, but as others have said...stick to a 4 pot if you want to Turbo it. Welcome aboard the madhouse btw :)
 
Ginja's not far off the money on that post :eek:


The advantage of looking at an engine on the deck, as Mark and Tony will verify is that it goes a better picture for a project than seeing it in the car. With the precats removed and custom 3-2-1 manifolds there is room for 2 turbos. The pipe work would be ludicrous and the work required to the engine would be nothing short of immense. Also the best performance would be gained with a sequential turbo setup so that a smaller one spins first and then engages a bigger one at the back of the engine eliminating lag and giving a cleaner boost. That in itself is a stupid amount of cash to make work and be reliable. You could probably go V8 and 4WD for less lol.
 
how about the supercharger route that shagmonkey took? 380bhp sounds Grrrrrraaate! But the charger would have to be imported from Nautilus (USA) as Vorteck (USA) do not produce the chargers any more.
