Hi lads, i was thinking about the new vw diesel pd engine and how much bhp you can get from them
and thought what would it be like in a kit?? i know
youll probly say why??? cos its a heavy old beast but.....huge amounts of torque and real cheap to run. i supose making it rwd would be a problem. are
the newer engines being made lighter yet???? cheers
i've got a chipped pd and the traction control has a job as it is. the torque would be unmanagable in a locost assuming you could fit it in, its
not the smallest of engines 
Ned.
i have a 3lt dti vectra with a power link box and myself had thought about a derv locost. . .v6 2.5 audi lump there must be some floating around in the scrappy
My 110 tdi passat will spin up easily. Iv thought of locosting with one aswell. They are a big engine though.
If u were to put a 130 in and chip it to 150 and put a 6 spd box it would be awesome. Good tyres needed on the rear i think.
Run it on chip fat would cost about 5 quid to do 400 miles
I Have a Golf PD150 and it goes like stink (No not like a chip shop
). not as hot as a petrol off the line but mid range
well
i dont think that i would like to run a locost with one in as the torque would spin the wheels with ease.
a solution to it being for a FWD and the lack of weight over the driving wheels would be to put one in a Middy. what do you think.

I've seen old Land Rovers putting out 180BHP and 300 lbs ft using two fuel chips and a propane injection kit!!!
Normally only 70-80% of the injected fuel gets burnt hence loads of sooty smoke out the back. If you inject propane or similar you get over 90% of the
diesel to burn so more power and cleaner emissions.
If you want a RWD diesel, get one out of a van. Transists can be RWD (not that I'm suggesting you fit a Ford diesel) so WV vans may be RWD.
It isn't torque at the flywheel that should worry you so much as torque at the wheels. Choose the right diff ratio and wheel size and
you'll be OK.
Diesel engines are often quite heavy and so they will spoil all your good work in making a light weight sports car. Citroen's new HDi engines
(1.4 and 1.6) are all alloy and weigh just a fraction more than their equivelent petrols. The high power versions are very rare as you have to buy
the highest level of trim before you can opt for the big engine.
My wifes C3 has a 1.4 HDI , must admit performance is lively , when we tried demonstrator at main dealers they only had the 16v , well impressed with that
Found this American forum discussing propane injection: funny....smoke dem tyres! Oli.

I have a skoda fabia pd100 with allard phase 3 conversion including fmic, pd130 turbo, pd150 injectors, miguel remap pushing out 195 bhp and over 320
lb ft torque remarkably the clutch is coping and it puts the power down quite well on seat ronal 16" alloys.
I am extremely interested in building / locating a diesel westfield, caterham etc. and would appreciate any advice.
Is the main drawback that most diesel cars power the front wheels and so it's almost impossible to get a rwd transmission set-up?
Best wishes

Yep, Id think thats one major obstacle, you'd struggle to get a suitable gearbox thats small / light /strong enough.
ive had a chipped PD 150 Quattro Audi, (see images) up to 190BHP with 400nm, and it was amazingly fast car but power comes in very sharp, 2wd would be a nightmare to control!
how about mid engined using a passat gearbox?
Paul
It will be VERY heavy though, diesel engines are significantly heavier than equivalent petrol engine due to stronger components needed to withstand the high torque and high compression ratios. I wouldnt be suprised if a 1.9TDi VAG engine and box weighed well over 200kgs
I remember asking on here a similar question a while ago, main issue seems to be the nose/vibration issues that i derv will have. Also not as many tuning options.

torque curve of diesel would be totally unsuited and awful to drive in a locost!
If you could map the injection on a common rail diesel to give a more linear power delivery then you might have something useful for a locost,
otherwise they are great for people that can't be bothered to change out of fifth gear when they want to overtake!!
Hi,
excuse my ignorange is a passat tdi rwd?
John
no
either FWD or 4WD (4motion)
been thinking about this some more, maybe in the back of an aeon (or maybe not)
Would it be more viable to source a bmw based donor engine and transmission becuse of the rwd?
Best wishes
John
