Like the title says, i`m curious to if anyone has transplanted the 3 cyl 1.4 diesel from the Polo into a retro VW, like, for instance a Derby (cough cough)  |

We have a Skoda 1.4 diesel and can say it's a good lump. Plenty of power and you don't notice small capacity or loss of a cylinder. Quick for a diesel as well. In the Skoda there are 3 different power output versions. A 1.9 VRS diesel transplant could make a neat "street sleeper"

there must be something wrong with the 1.4 3 pot oil burner in my 9n polo, i find it worse than gutless! power delivery is like an on/off switch, overtakes need to be planned miles in advance, oh and it isn't the smoothest sounding engines. Compared with my wifes cordoba which has the 1.9 tdi it is rubbish, fuel economy isn't that much better and tbh I'd rather have the extra 60bhp and loose a bit of mpg.
The whole concept of putting it in a derby is a no go anyway as it was basically a 1.9 block minus a cylinder, this means it was derived from the vw tall block engines so would need a custom subframe making to fit it in. It is do-able if you have a bottomless pit of money or if you are an engineering god.
There was a derv option on the mk2f, never available in the uk though, but the same engine was used in the seat terra van which was available in the uk, but a pretty rare sight these days. In fact I can't remember the last time i saw one.

No idea why your Polo is so different to our Fabia. We get 55mpg around town and easy 70+ mpg on a run. Engine is smooth and quiet. Sound like a straight six diesel on acceleration. Tows great - A framed my Austin Sprite 200 miles and didn't even know it was there plus economy almost as good as solo. Didn't hang around either and 50-60 mph cruise on motorway. I think we have the most powerful of the 3 versions so maybe your is the base / low power version ?

tbh i think the problem is me being used to driving faster cars. from memory my 9n has the 75bhp 3 pot, so it isn't the lowest power one. Also get similar mpg figures too.

After years of V8's (3 x Range Rover, MGB GT V8 & SD1) as well as Jags (3.4 S2 XJ6 & 2.9 XJ40) the economy of the little Skoda diesel is amazing - better than my everyday Smart Fortwo ! Paul h |

id say theres something wrong with yours, ours (a TDI sport lupo, with a badger5 map running a dyno proven 105hp) is far, far quicker than a 1.4 diesel should ever be, its capable of embarrassing a LOT more exotic machinery up to 90mph or so.
they're 75hp as stock so ours is 40% up on that, but they're restricted by 15-20hp by the factory as the performance figures were too close to the other sport models. with any street driven car what you really notice is the torque though. the tdi sport is 144ft/lbs as stock, thats way higher than the 16v petrol sport or even the gti. ours is over 170 ft/lbs from memory, the kick in the back from the turbo kicking in a 2200rpm has it squirrelling and torque-steering all over the place if you don't keep it in check. all this whilst still doing 65mpgs.
the only reason ive not looked at fitting one to something else yet is the price they command. ive got a 1.7 izuzu td to use cos they're 300 quid, whereas even a written off tdi sport is at least 1500 quid. give it a few years and ile be doing it.

^ I don't really see how you can just say there is something wrong with my slow tdi, when you are making comparisons with a re-mapped one. Look at the performance data for a std polo 1.4 tdi. It is slow, it is economical, it was never intended to be anything other than a practical and cheap runb around, exactly what my car is! proof of the slowness: www.theaa.com/allaboutcars/cartestreports/car_test_report.jsp?reportNumber=R0251You go from having a mildly tuned polo g40 as a daily runner to driving a stock polo 3 pot tdi and it is gonna feel slow. I know people rate them once re-mapped, but in stock trim it is about as bland, as bland gets. |

I'd agree with those that say the performance of the 3 pot TDi is pretty spritely. I had a stock Arosa TDi briefly and when it came on boost it would really get up and go. The Lupo/Arosa SDis, now there is a slow unrefined engine.

I`d assume it would run pretty well in a 70`s VW Derby then, seeing as that weighs about as much as a damp paper towel  |

you didn't read the bit where I stated it wont fit without a custom subframe then!, oh and you won't be able to lower it and finally it will handle like a turd. It isn't the lightest engine around, in fact in my 9n the car feels nose heavy, compared with the petrol alternative. If you were going to go to the trouble of fitting a tall block engine in an 86c chassis, you might aswell fit a 4 pot tdi and have all the benifits of having the extra cylinder (if you think a 3 pot derv with 75bhp is nippy, a 150 bhp 4 pot tdi will blow your mind). There is a guy on polo3.co.uk who has a mk2f square running a 1.4 1w block tdi with around 180 bhp if not more, and that doesn't require anywhere near as much work to fit in the engine bay. see linky: z8.invisionfree.com/POLO3/index.php?showtopic=7338 |

I really want to stick a remaped one in a base model mk1 golf or a caddy, just because lol.
That and it being under 1.5 so it would be in the cheaper tax braket.
I searched for hours & I think I found 1 thread about it but I didnt save it.

Still won't be that cheap to tax though. From what I can gather, the conversion would be similar to fitting a 1.9 tdi, which has been done a few times in mk1 golfs and caddys. If you are serious about the conversion you might wanna try and tap some info out of these guys www.golfmk1.co.uk/conversions.htm |

However as long as a pre March 2001 vehicle DVLA base road tax on engine capacity. I was interested in changing the engine in my 1.6 Vitara to 1.5 diesel and DVLA confirmed in writing that as long as I got a report saying the smaller capacity then they would rerate the lower VED band.

Yeah, but what I'm am getting at is that the smaller capicity tax band for pre 2001 cars isn't that cheap, i.e. it is still gonna be £130 or whatever it is now for 12 months tax, whereas the same 1.4 engine might only be £30 a year if fitted in a newer car.

I see what you mean now. Our 54 reg 1.4 diesel Fabia is £105.00 pa. Paul H |

It's alot better than the £270 it cost's for my golf lol. From what ive read you can get about 150bhp quite easily from the 1.4tdi, which should be a bit lighter than the 1.9. Would like to see one fo these engines in something retro just to see how much room they take up. Edit - fit's in a beetle! www.volkszone.com/VZi/showthread.php?t=820926As said though, it does look very tall! www.ebay.co.uk/itm/VW-AMF-1-4-TDi-engine-block-and-head-Lupo-Polo-A2-New-genuine-VW-part-/121138109079 |

Drove the 1400 75ps diesel in an A2 and it was quite sprightly. Especially considering it has 200k on the clock....

Tall block? Go for the 1.9TDi, all the same work as the 1.4 and you get the (big) power gains. There are modded Lupos running the 1.9 PD units and they seem to utilise the 5-speed Polo 9N 105hp PD gearbox over the usual six speed on the 130/150/160hp units.
Road tax? The tax should be worked out on the age of the engine going in, not the chassis it sits in. So if you go for a post 2001, then you might not need to worry. However, if the £140 a year makes that much difference to your life, then I'd question doing the job in the first place.
Handling? It'll probably be awful because of the weight. I'd go for custom springs and shocks to cope and big ARBs.
Kudos? Yes, because it's not a 1.8T
Alternatives? VTEC, Yo!
