Thread: a fuel efficient Series 3 ??? a dream??

I'll back the conversion to one of the rover diesels as the 200tdi fitted sans turbo or the normal diesel 2.2 as originally fitted if you still have the original box on should be a drop in once you deconvert it from the holden..

the 200tdi is a bit more pricey on parts but a lot more effecient on fuel if looked after and the parts for the stock 2.25 diesel cost peanuts. As an example I can rebuild all 4 injectors for the 2.25 for the general cost of one injector for the 200tdi. As a bonus both these diesels tolerate a wide fuel range from essentially sweet light crude (not quite but bloody close once they get warmed up) through to AVTUR and that includes some of the crudest biodiesel you'll ever see.

Please tell me where these cheap parts are I have five diesel engines

They have efficiency better than most full size trucks, at best point they beat an Isuzu 4BD1T by almost 10%.

And Jimfoo on pirate has fitted one to his series, so it has been done.

The 2.5tdi's would be your next choice. Stay away from any indirect injection diesels, they're around 20% less efficient than direct injection tdi's.
Isuzu did a 1.7l non turbo diesel in honda civics in europe. Not sure where you'd find one though and a turbo would certainly be worth the extra.

Is that the 1.9 tdi in the current golfs?

An installation of this motor in the Passat "bluemotion". This car is returning a combined consumption of 55.4 MPG. That's 5.1 l/100. For a car nearly the size of a falcon that's pretty impressive. See the bluemotion here.

EDIT: I got carried away with my rant. I've only seen it in FWD installations... it wouldn't be easy to get into a N/S series let alone the cost of one!

This is in fact the same basic engine as the L series diesel out of the Freelander - a pretty bullet proof engine and as you said a common mod for the a series landy in the UK. I have never seen one of these engines for sale in Australia but I suppose they are out there.

A 200 TDI is probably easier to do but bits are hard to find but the L series would probably give a bit better performance - though it does have a computer it is very much self contained and very reliable.

what parts do you need.

Basically yes, but you'd be looking for one of the older mechanical injection versions.
If you get one with an electronic injector pump you can probably retrofit a mechanical pump, but if you get a pump deus or commonrail you'll be in for a challenge.

To add to the list of options, the 4JB1T (2.8TD) is a good engine, and is very common in australia as it was fitted to heaps of rodeos and jackaroos. However, you would have to be very easy on the loud pedal to save the gearbox (same as if running a 200Tdi - with turbo).

This company has kits for the 4JB1 and perkins prima 2.0.

EDIT - however it seems there are NA versions of the 4JB1 - probably from forklifts etc...

I have a mate that has 2 series with these motors and gear box combination,s fitted and a couple of spare motors and gearbox,s which he will not part with for love or money

They are a great combination for the series landy and a torque monster to boot
And very economical

I had this in a SIII, it was the worst engineered conversion I've ever seen. Some run really well, most are just that bit out of alignbment that t/cases scream and gearboxes break. The problem is a heavy cast iron box suspended between a torquey diesel and a firmly mounted t/case. The adaptors were all alloy with no helicoils or anything and as the motor flexed with acceleration, it stressed and eventually broke the bolts. It also stuffed the mating surfaces and the t/case howelled as well as dropped lots of oil. The motor was great, the adaptors were less than precisely manufactured.

I think your best option for long term ownership would be to get a 300Tdi disco that's been damaged and use the entire transmission, even converting to coil springs on the SII. Using a 200Tdi will limit your options later if you need to repair or replace the R380 Gearbox.
