The CT engine is almost just a petrol version of the 2.1TD... mechanicals are the same although the gearbox is a tad shorter.."
So does that mean other pumps can be tweeked? Bosch?CitroJim wrote:With the EPIC pump Chris, no the 2.1TD cannot be tweaked at all, it's completely electronically controlled and "fly by wire" so to do any tweaking at all, the ECU would need to be modified and that's a whole different ball-game.
Unfortunatly that's the problem I have with the Activa, yes it's a cheap car, but it's cheap because it's expensive to run (even when trying your hardest to be economcal) and expensive to maintain. If I could make it cheaper to run and keep on top of maintainance then it's the perfect car in my opinion.Sl4yer wrote:Rather than the conversion, why not try chipping (or remapping) the CT? 180bhp should be easy, and although torque won't be up to diesel levels, I'm sure it would make a nice difference. Superchips do one for about £400, and various independants claim to be able to do it for about half that. It's got to be a cheaper and pokier option that swapping a diesel in - I reckon economy could be improved too, but probably not to an acceptable level.

To be honest James it's a bit of both. The price you pay because of the poor economy isn't justified by it's lack of performance. My brother was saying that the economy isn't that bad because he's comparing it to his last two cars, one being a 250hp MR2 turbo at around 22 mpg and 1260kg's, the current car being a Honda S2000 at around 240hp, 1300 kgs and 25mpg. It can't be pinned on the fact that it's a heavy car either because there's a maximum of 240kgs in it. Also my parents have a 2000 Saab 93 Aero, 205hp, 32 mpg, not sure on the weight but it can't be far off 1500kgs..? It also has peak torque at something like 2200 rpm, so it's definatly a 'constant torque' sort of engine.Sl4yer wrote:Ah, is the problem lack of performance, or cost?
As Gareth found out, Activas could do to be a bit quicker. I find that I don't like to rev mine too hard, partly because I'm used to driving diesels and partly because people sound like knobs when they use all the revs in an urban environment. It's quick enough for me, but I'd really like it a bit quicker.
The economy is the real killer for me. 20mpg isn't really acceptable. But I feel better that if I lived 15 miles from work, rather than 6, it would cost me just as much in an efficient car! When I bought it, I imagined that my partner would do much of her longer-distance motorway journeys in the Activa, and I would use the ZX for work. But she won't drive it!
Superchips claim an improvement in output at very low revs for similar engines (such as the Saab LPTs). If the same was true for the CT, economy around town could probably be improved by the mod. But it's an expensive chance, and not one I can afford with a wedding and hopefully a baby arriving rapidly!

I wouldn't disagree with much of that Dom. That's why I think it needs a chip or remap (or a new turbo if you have the means!).Dommo wrote:Put simply the CT engine is just a s**t, gutless, thirsty engine at OEM spec. Anyone that says otherwise in my opinion hasn't had experience of other good petrol turbo engines.
Your wrong, and i have plenty of experience with other turbocharged petrol cars.Dommo wrote: Put simply the CT engine is just a s**t, gutless, thirsty engine at OEM spec. Anyone that says otherwise in my opinion hasn't had experience of other good petrol turbo engines.
