Right, over summer, when I get back from uni, I'm going to hopefully convert my SE5a Scimitar, from a boat-anchor essex v6, to some form of diesel Hoping to eventually upgrade to a 5 speed (currently 4 speed, with dodgy overdrive setup) but that will most likely need a custom propshaft, and my funds won't spread that far - so it needs to be able to fit upto the existing 'box. An adaptor may be possible, but there's not many engineering places in norfolk (at least, not within 2 hours drive!) The engine, has to be a fairly common, 4 cyl thing - because if there's one in my local scrappy, I can get whole engines for £100  Already thought of a Rover L-series, but the diesel pump is on the flywheel side, ran off a 2nd belt (two belts to change, and changing the 2nd one would mean removing the engine, or cutting out the bulkhead) Looked at fords, and whilst they may have the curse word lucas pump, they're quite common - anyone know of any downfalls? Vaux 1.5 and 1.7 diesels are quite common, but again, anyone know of any reliability problems? Eventual plans will be compound-charged, and fitting my mahoosive intercooler  engine bay is quite large, and the engine can always be held at an angle to clear the steering rack if it's a bit too long - but a straight 6 is too big.. needs the bulkhead chopping out, and I don't have that much time, talking about a week or two max conversion time  so, throw around some thoughts/ideas for me - lets see what you can come up with  |

Vag TDI.
My non turbo 1.9 is good for a ton in the heavy MK3 golf though I'm guessing you'd want turbo performance for a degree of acceleration.

early VAG TDs non ECU either 1.6 from Golf or Passat B3 (ive got one in my caddy pickup) standard around 75 horse tuned upto a reliable 120
or the AAZ 1.9 TD not TDI from Golf MK3/Vento etc..90 standard again can be "tuned" to about 120 horse..
should be plenty about and failry robust..

well, they'll let me have a turbo for £20 - intercooled L-series diesel turbos (on an L-series anyway) are good for 150Bhp without getting into a sweat... got a turbo off a 3L frontera for the 2nd turbo Also, are the VAGs mechanical pumps, or electronic? If they're electronic, but with the Bosch pump, that's relatively easy to swap over for a mech jobby... but electronic pumps are just a PITA |

Mercedes OM601/W124 (200D)? Bomb proof - though not very powerfull at 72 odd horses...  Or a 250D (OM602, five pot), bit more powerfull, 90-96BHP (2V) or 113BHP (4V). But at least as reliable. Turbo engines are rare though... Both 200 and 250 have a bomb proof Bosch inline pump. All the manual 250D came with a five speed (high 5th) from factory, not sure about the 200D... Both 100% mechanical, I think the later 4V engines had a bit of electronic stuff to them... I'm currently driving a five pot mercedes diesel - and love it to bits!  310k on the clock and never missed a beat A mate of me has the same engine with 500k on the clock - never missed a beat either. Does 37-40MPG ( 1.5 tonnes). |

ooooh fun project, compound turbo big 'cooler, but what engine, hmmmmm
You need something that is old skool diesel tech, so mechanical or PD, Omega or BMW 2.5 straight six lump? However does not fit in with the 4cyl theme.
Ummmm, how about a peugeot / citroen item? use a 505 gearbox?

Blown_Imp, already thought of the french diesel (my old 406 was really reliable, and did 50mpg) but 505s, let alone the 'box, is more awkward to find, than a virgin prostitute  VW engines look like a good choice - would need a nice simple plate drilling up, to adapt the flywheel (possibly - as they're both 6-bolt) and an adaptor plate to convert from block-fit, to bolt onto the 'box And what's even better - if I get the engine over easter, and can get some measurements of the essex bellhousing pattern, I can even get the adaptors waterjet cut at uni, for either a couple of pennies, or even freeeee! As for the clutch, may be able to just swap out certain parts (friction plate) to make a weird hybrid clutch, or, get the flywheel redrilled, and rebalanced to suit the essex clutch - as apparently, the one fitted to mine is quite new merc engines annoyingly, aren't going to be particularly common (esp an old 200/250) so may not be able to get one... but will look into them, just in case! But... it seems we may have a winner, in form of a VW 1.6 anything else that pops to mind though folks? |

good motors, just watch out for a few little things..oil cooler failing causing head gasket type symptoms..and head gaskets...think you can swap them out to 1.9TD metal ones..
tuning wise check the caddyforum plenty one there.

Why not a Ford diesel ? That would mate to a five speed without an adapter. Whilst a 1.8 turbo might be a bit tame what about the 2.2 Duratorq TDCi lump. Then there is always the 3.0 V6 diesel out of Discovery, S Type or special order Transit (if you can find one ) Paul H |

funnily I was going to ask this question.
I'm interested in which modern "decent to drive" diesels can be easily transplanted into an older RWD car. A lot of the older diesels are horrible. Noisy, smokey, not much power, not brilliant economy (seen the price of diesel lately?)
But a lot of the modern diesels look like a nightmare of plumbing and and computers.
Hmmm

stefan, the essex v6 works reasonably well - no idea about top-end power, as the whole car shakes at anything above 65mph (NEED to get the wheels balanced!) but I think the carb needs rejetting - was from a Capri 3000Gt, and I doubt it's been touched since the day it was built tbh! And TDCi = common rail = lots of electronics = ECU, and wiring loom transplant too. The Scimitars Lucas-based wiring loom is marginal at best, I wouldn't want the running of my engine to depend on it :s Oil cooler was going to be a definate, as for quite a small engine, it's going to be put under quite a lot of stress - was going to go for quite a large cooler, with a thermostat And, from what I've seen, anything newer than about 1980 deisel-wise, seem to be quite good drives I know the vw diesel's not so bad, as my mate had an intercooled diesel golf last year |

Gotta be a 2.5 VM TD from a scorpio surely, a 1.6 VW effort is gonna be grim until you have souped it up to the max.

lol, saw that video last night strangely enough! No idea *what* pug engine it is though scorpio, again, would be nice... but because it's "retro", people seem to want ridiculous prices for parts and as said, a straight 6 is possible, but it's not exactly a quick conversion - whole dash needs ripping out, to cut a whole in the bulkhead, then the whole needs to be sealed up again. And don't forget, this body is fibreglass, not steel - can't just weld a bit of sheet steel in there, needs a good day or so to sort out just covering the hole up |
