My previous car was a 51 reg 1.9 TDi Toledo, the TDi poke was great, especially for overtaking on the Motorway. This had 110bhp and 235nm.

My current car is an 04 Skoda Fabia VRS 1.9TDi (PD) and the 130bhp power and 310nm torque are excellent. This is all the fast I need to go, so I wouldn't conside remapping the VRS.

BUT I want a lightweight, 100bhp+ car for some fun, but it would also need to be my commuting car too. I have no room for two cars so a 205 GTI in addition to my VRS is not an option.

I'm very tempted to get a 1.4 TDi Arosa and remap it to around 110bhp and 250nm. If that sort of power and torque was good in the Toledo so i'm expecting it to be even better in a car that is several hundered Kg less in weight. The VRS is 1300kg which is a fair bit of weight over an Arosa.

It is likely that it'll be a disappointment compared to my VRS. With 20bhp + 50nm less but a lot lighter at around 970kg.

I've also put the same question to the SEAT forum.

Thanks

I'd be suprised if you will get the 75bhp unit up to 110bhp safely, 100bhp is usually the max but they dont half fly with it.

Thanks for the advice.

A couple of remap people "claim" 110 but I don't know what would need to be uprated to cope with this. Every BHP down from 110 will need to be offset by removing something that adds weight. No.1 back seats....

The turbo is tiny on the 3cyl plus the blocks arent as strong as the four cylinder counterpart (neither is the 120 degree crank) so you have to be carefull when mapping.

Not sure if the Lupo intercooler is the same but the end caps pop off the std Audi A2 one when mapped (even std sometimes).

Its starting to sound like an over ambitious project! I can't find another car under 1T that has a map-able TD engine. Its got to be diesel due to a 35,000 miles per year.

If it's any help, our petrol Lupo with 100BHP and IIRC 943kg is quite good fun, but felt slower than the Fabia despite a similar power to weight. I think some of it is that the vRS felt quicker than it is. The 16v is obviously very different in character to a TDI.

Have you thought about asking on http://www.clublupo.co.uk ?

We did have a Polo 6N with the 75BHP TDI. It's a good engine, and fast enough to be fun, but nowhere near as fast as a Fabia vRS. As Lummox has said, 90-100 BHP seems a reasonable output from one mapped.

A friend of mine has a 1.4TDI Audi A2. The 90 bhp model. This is remapped to 110-115ish bhp and it goes really well. He has had it lowered and it is on 18s too. Is a very nice car,

TBH i think a remap and some handling tweeks to your vRS would bemore suitable.

Didn't know they did an 90bhp version, a fair bit for a 3 cyl diesel engine. I know its possible to get more out of the 75bhp unit, just need to exercise caution. Small gearbox and flywheel/clutch on the Loop also.

You can get a 3 door Fiat Punto JTD which will map to about 120bhp. You can pick them up for peanuts and this will be at least as quick as your VRS given it only tips the scale at 1040kg. It should be good for about 50mpg on a run at least

The APS A2 was mapped, IIRC it was about 90ish bhp, 3 cylinder, and coz the A2 is so light, it was reasonably nippy although the ESP turns itself back on again and does slow down 'take off' a little.

Ive seen the 1.4TDi units map up to 120bhp and 200lb.ft without any problems (so far!)

With a weight of 1000KG's id imagine they are very quick, but also very rare, I was looking at one 3 months ago, and only found one in the country for sale, which disappeared soon after I asked about...

Id say with support mods 120bhp is do-able, much like a vRS will map to more than 170bhp some people doubt it, but it can happen!

Get a classic mini, 600kg and 110bhp

why not try and put the vrs engine into a arosa?

Or is that just silly?

Yes, yes it is.

Its a chance you take I guess, seen more than one standard 1.4 throw a rod through the front of the block.

Yes, yes it is.

Hmm thought so

Although why am not sure cause you can get the 1.0sdi lump in the lupa as normal cant you? surly the size differance cant be that much between the sdi and thr tdi?

Completely different engine.

The SDI engine is a 1.7 diesel of the same ilk as the Felicia lump.

Can't say ive seen a 1.0 diesel.

I presume you are English?

A 1.0 diesel engine?

If you can get one, get me two.......

My friend has a Polo Colour Concept and recons with PD130 injectors (3 of them) and a custom map it should hit 120bhp.... should fly

Can be good for the OEM turbo or IC surely?

No, the SDI is 1.7 in the Lupo/Arosa. I presume you meant to type 1.9?

Of course, given enough cash and time you could get a PD130 in there (people have done 1.8T and VR6 IIRC), but it would cost.

Only the A2 I think, and early ones were 75 Like the Lupo/Polo, so it wasn't in production for long.

which mini had 110bhp and weighed only 600Kg?

It's not hard to fettle a 1275 to stage 3 and strip it down. It's also not that hard to turbo one if you can get the bits.

BTW The Daihatsu Charade was fitted with a 1.0 TD from around 87 to 94

Edited 6 April, 200917 yr by Decron

a 1.4 pd lump will make a lot more than 120bhp but not with any degree of reliability....

i've secretly been working on a special intercooler for mine:D

Its starting to sound like an over ambitious project! I can't find another car under 1T that has a map-able TD engine. Its got to be diesel due to a 35,000 miles per year.

If you're doing that sort of annual mileage, why get something smaller than the Fabia? With that distance I'd want something that was comfortable and civilised.

Keep the vRS, and update suspension/bushes and add a R-ARB if you want to improve the handling and 'fun' factor.
