I can see I need to let you drive the Griff again - talking about torque and weight like that ;)

Diseasal is a very good idea - and it's something no-one has tried as far as I know.  (Plus I can make my own fuel)  It'll be probably be full price tax, but at 60 or 70 to the gallon, who cares!

Dailly driver is 1.9 Passot tdi 110 bhp 204,000 miles and genrally abussed apart from oil and filter every 10k.

PPC magazine has a feature on a chap fitting a 1.9 VAG into a westie.

the main issue I can see with that is final drive ratio ( the same issue as fitting the v8 )  you would need somthing arround the 3.1 to 1 diff the good old sierra is used for the diffs in most 7's. There is a 3.14 version but 'Hens teath' springs to mind as it was in the 2.3 Deisel plus the are £££ trust me I have one add the LSD unit its even more. !!!!

what diff does the Trevor run ?

Mine has an old GKN diff which (I think) came from a Jag XJS originally.  TVR had it modified with an LSD unit. 
Final drive in all cases is approx 3.3, and they're like hens teeth too!

The newer ones use a BTR unit and some have a hydratrack diff.  (not sure if this is a trade name for the whole unit or just the LS part)  Not sure on the ratios, but I think they are similar.

I thought about using a UK Impreza diff - they come in 3.45:1 and 3.9:1 ratios.  Jap stuff is just silly - the RA is 4.44:1!

Hey no fair - you changed the rules!  :D

If Truck engines are an option then I'd say find the TDi from a Seat Leon Cupra or Golf GTTDi (150bhp) and fit the whole lot in the back of a series 1 elise.

Semi-practical car, less problems with the extra weight affecting weight distribution, box suits the engine and as much power as the car originally had with buckets more torque!

Cliff - that sounds all together too much like a plan!  :D 

I wonder what the insurance would be like?

VEMS controlled VAG Oil burner now there a thing. what controls the variable turbo on those ECU ? I know it has an fuel  ECU as mine had a diky fit once. are the injectors ecu controled ?

I think the ECU does control the turbo on the VW PD lumps and i'd guess the injectors are ECU controlled.

The best buy is a PD 130BHP lump and not a 150BHP lump as they are rarer and go for a lot more money...The 130's in a Golf or Audi with a uprated intercooler and a remap will do 200bhp all day apparently. They also share some bottom end bits with the 150 so its a pretty strong engine.

I have recently got a Golf Mk4 with a 115PD unit fitted, which peaks at 210lb/ft of torque....

Vems has no chance of controlling an engine like that unfortuantely. The injector driving for common rail diesel is pretty complicated stuff (like gasoline DI only worse  :-\) You'd need to keep the original ECU, and probably several other modules for immobiliser etc. Wouldn't be totally straightforward, but I'm sure its do-able. There seem to be plenty of diesel tuning specialists springing up that could surely help you understand what you need.

Insurance isn't going to be worse than any other one-off I wouldn't expect. At the end of the day its just an engine swap, and there's plenty of elises with 1.8T engines now, so its not entirely new.

Rich - some good advice there.  :)

Now I'm going to stop as I'm really not interested in the dirty smelly things (Bah humbug....)
