I drove my dads zx td before deciding to go for the 16v petrol but I do understand where you are coming from.
Would quite like to try a modern diesel, one of the 138bhp psa ones. That new 160bhp Seat Ibiza is very quick on paper as well.

The 90 bhp xud9te engine has the almost exactly the same torque (a fraction more i think) than the GTI 6 with the 170+ bhp engine. They are indeed excellent on twisty,uphill B roads.

I have a ZX 16v and a ZX TD Volcane I regularly drive them both, not at the same time though![:o)] I would say the TD is a better all round car, it's fun when you push it and economical when not, it has the same suspension as the 16v (16v shocks are firmer) so it's as agile on the twisty bits.
The 16v is torquey but to get anywhere you have to rag the nuts off it! It is quick though!! For an old car it goes.....[:D] You can't compare it to the newer cars, its old school.
Hard one to call really.

not my one Gareth, mines all go just under 3k and then gutless high up, no idea why, perhaps because its one of the weird 150bhp ones or its been remapped at some point in its life. Means its great down the lanes but rubbish on open roads as it has no go high up.
ah yes, the 16v is group 15 insurance

Mines costing me £327 a year 3rd party fire and theft which isnt too bad

and with group 5 insurance!
Yup! Although mine is actually group 4 because its a xtdt, not the sportier looking dturbo. 230 odd quid a year fully comp for a 24 year old - not too bad!

Who do you insure your car with? Its a very good price.

on top of all this, it is actually very easy to "tune up" the 1.9 diesel XUD9TE engine to some very large power outputs. With a little fettling, a tweak of the turbo, relocation of the intercooler and a prod of the injection pump, 130hp and over 200lbf-ft of torque is entirely possible. Makes a 405 diesel estate faster off the lights than an escort XR3i, with some very very embarrased looking boy racers. hahaha! Plus it still managed a good 45mpg when not being hoofed everywhere.
being somewhat more sensibe too, the towing capability of a turbodiesel engine is far better than most petrol engines, and still retains most of it's economy.

David, are there any websites with details on these sorts of mods "a tweak of the turbo, relocation of the intercooler and a prod of the injection pump" etc as ive wondered about the effectiveness of a TD in a sprint/hillclimb which i take part in. You see the engine splits are upto 1.4 litre, then 1.4 to 2 litre. However a diesel car has 60% taken off its CC and then as it has a turbo it has 40% added back on (something like that) so it means a 1.9TD can run in the under 1.4 litre class. A zx volcane beefed up to 130bhp with 16v brakes and suspension would be quite effective in that class.

Have a look on the links pages.I had mine done to 115bhp just by the fuel pump.Although my i/c is next to the rad,not on top of the engine.

to be honest, most information I have ever found on the net to do with engine tuning has been erronious in some way or another (some are just blatently wrong) so I can't reccomend anywhere. All the tune-up work I have ever done has been of my own design.
sorry... that probably doesn't help much does it!

heh no worries, will see what i can find, only curious really anyway

David, How did you get around the shape of the intake, the intercooler normally connects to?
The feed pipe off the turbo is easy enough to re-route/extend to a front mounted intercooler, but when the return pipework gets to the intake manifold, how did you connect it??
Did you have to custom make a mating plate?
What sort of Psi are you running the turbo at?
Are you using a different air filter?
Just a few questions[:D][:D] Any help would be great.

That partucular point had to come up at some point. It's been modified a number of times:
Initially I made up a mounting plate to bolt to the intake manifold, which allowed a big diameter pipe to attatch. That was horrible as it was a nasty restriction. MKii was then to cut the manifold about, and aluminium weld a pipe attatchment point to it. That worked a lot better, but I was finding that there was imbalance between cylinders, mainly a low pressure at cyl 4 due to it's remoteness from the main manifold area. Next attempt was the intake manifold from a pug 605. Almost worked, but being from a 12V head rather than an 8V, it didn't quite clear everything. Final (and best) solution is the intake manifold from a Talbot Horizon diesel. Very nice design actually, with a splitter in the middle of the intake. This allows easy connection from a large diameter pipe, and has given the best performance, although getting the pressure pipe out from the turbo to the front of the car was a little interesting: the fresh air side of the turbo is now upside down, with the pipe running down, and under the engine, through that really handy rise in the gearbox end of the sump.
I run the system at a reasonable 12psi, but it's generating that from about 1400rpm, after some attention to the internals of the exhaust manifold. Has been very reliable so far, and superbly powerful.

forgot to say... the standard air filter got binned too... it now runs with an oil-wetted sponge filter. I like these, as they are washable, and re-useable, and offer very little resistance to airflow. That got relocated too, as the standard pipework is a bit of a spider's web.
speaking of silly pipework installations... has anyone seen the intake pipe on a non-turbo diesel xantia? utter muppetry!
