Petrol to Diesel?
So... somewhere between idle speculation and an idea for a future (i.e. very future) project lies this question:
Can I take a petrol car and put a diesel engine in it? Preferably an engine from another manufacturer?
I'd like to pick up a 406 exec saloon in really good condition but fit it out with a mighty parful diesel plant, something ridiculous like a V8 twin tub. Then hit ecosse pug and buy an obscene bodykit.
Where does this score between cool project idea and total, utter insanity?

depends how much cash /time you have as anything can be done,but if youwant a diesel over 2.2 me thinks rear wheel drive so theres your first proplem
Re: Petrol to Diesel?
Have you seen the engine bay of the V6? There's not a lot of room in there. Someone once did a twin turbo upgrade to their V6 and apart from costing an obscene amount in pipework (around 10000 euros iirc) there wasn't even room for the fusebox, so a V8 is right out the window (not that I think you'll find one in FWD setup...)
You might be able to fit the 407s 2.7V6 diesel in there though, but you're probably looking custom ECU

Re: Petrol to Diesel?
Hmm... yes, that might do the job nicely... thanks ^^
Ooh, so I could pick up a nice, recent-reg HDi exec and put the 2.7 in it... then have it tuned up for loads of bhp so it's fast as frakk and burns out in three years. Awesomeo powah! ^_^

Re: Petrol to Diesel?
Know anyone with a degree in electronics? Would the 2.7 even fit? When I looked at a 407 SW, apart from the rediculously tiny boot the other thing I noticed was a lot more space under the hood (I suppose you could always put stuff there too...)
Btw Matt, my mate in the car spares shop says all they're getting just now are broken timing belts (something to do with the temperature?)

You can buy off-the-shelf generic ECUs. They just need setting up (mapping, etc) by expensive tuning placessteve_earwig wrote:Know anyone with a degree in electronics?
I just assumed given the 407 has a few 406 engines in the range that the space and mounting points would be similar...Would the 2.7 even fit?

Current one's got loadsamiles left before the cambelt's due, I don't do the ~600 miles a week I used to nowBtw Matt, my mate in the car spares shop says all they're getting just now are broken timing belts (something to do with the temperature?)

Re: Petrol to Diesel?
I'm just devoting most of my spare processing cycles to the issue of cars - my current one, what I'm going to replace it with and what I'd want to do for a 'project' car in the future. It saves me having to think about my college project.
The sensible thing might be a V6 petrol with the addition of a turbo... on the other hand I much prefer diesel (partly 'cos I can nick fuel from the ship) and I kind of like the idea of a pimped out schnell-mobile with a diesel plant rather than the expected petrol. Specially if I could then run said schnell-mobile on vege oil...
I dunno. Need to stop wasting my time with all these grand plans and get my horrible college work sorted really. Otherwise there won't be any money to pimp out anything

Re: Petrol to Diesel?
Modern twin-turbo 170 brake 2.2 would almost certainly fit - just a thought

Re: Petrol to Diesel?
I think a 2.2 HDi 136 remapped to the tits would be savage! Even through FWD.
Has anyone converted their 406 to RWD?
