So been thinking on chipping/remapping my Fiat Bravo 1.9 TD 75 and I can't find anywhere that does remapping or that even mentions the ecu, do these cars even have an ecu or not?

if yes, is it worth spending money getting it remapped? I already added a cone filter and will be doing an aftermarket exhaust soon.

TD has mehcanical injection pump. Best you can do is get TD100 parts (intercooler, pump and injectors) and swap them.
JTDs can be programmed as they have electronic injection.

Tuning the pump to deliver more fuel will give some power, but TD100 is better source.
Actually not sure if pump is straigth fit (gearing profile?) but the basic block should be same.

No remapping/chipping as it's all mechanical.

I drive a mech IDI car myself and have extensively modified it to produce a lot more power, for the princely sum of £90 (about €110). Make sure you have a strong clutch, brakes, tyres and suspension first, you'll need them.

A lot of the work is in the pump. Stick with the Bosch, Lucas pumps are rubbish. The TD75 from memory has 8mm distribution head, waaaay to small to work with. Source a VW 1.9TDI VE pump and use it's head (10mm) or in my case I used a 2.5 Transit DI pump head (11mm)

Things to look at include:

  • Timing advance (static and dynamic)
  • Gov shim
  • LDA grind
  • Case pressure mod
  • Distribution valve mods
  • Throttle arm adjustment

Just for the diesel pump to fuel for that hp.

You'll need an intercooler. Look at an Opel Vivaro cooler, just the right size for a diesel bumper cutout

As for turbos, the TD75 has a little GT1549 (there's one on a shelf behind me) bin it and ask yourself do you want a terrific all rounder or serious top end power.

Good all rounder: go for a medium sized vnt setup. This will require a bit of microcontroller trickery. Volvo D5 turbo/Merc C220CDI etc would fit that build. This provides good spool at low rpms and full boost at a low enough rpm. Brilliant in the city and if you're not interested in top end power. Something like a Garrett GT2056S would also fit this criteria

Top end power: I use a K14-2 from a 3.0 Mercedes on a 1.9 diesel on my daily car. Spool begins about 1200rpm and by 3k rpm full boost develops, all the way to 5k rpm. The crossover to full boost @ 2 bar is something else, the pull from 3k to 5k in 4th gear is unreal :worship::worship::worship: the only downside is the car smokes worse than a train sub 1 bar boost.... :yuck:

I have a full build thread here. Beware, it's extremely pic heavy and not a Fiat!!! Same principles apply :)

Any more q's just ask ;)

m20b25, I am thinking about fitting a bigger turbo and an intercooler inside my bravo. Now seeing as there is not much room to spare in the engine bay, how hard would it be for a guy that knows nothing to very little on engines to do this mod? Lets say I still cant make out which piece is the turbo in my car, its either hidden very well or sandwiched between the engine and one of the panels.

Also, side question, does it even make sense that the bravo comes with an oil cooler instead of an intercooler?

For an intercooler I managed to find a cheap Fiat coupe turbo one, its not the largest of intercoolers but its better than no intercooler right?
 
In the mean time I found the turbo lol :) it is hidden under some sort of heatshield in the front of the engine block, completely invisible from the top as all the cables and pipework go under the heatshield and you cant see anything, so I'm guessing a change of turbo (to a bigger one) would require some modification to the metal heatshield...
 
honestly, if you want to ruin a car, go and buy a 20 year old fiesta that nobody cares about, and rip the guts out of it, put in lots of pointless mods, waste a lot of money, and do lots of stupid things that you will regret, you'll doubtlessly break it, but perhaps most importantly you'll learn something.
but please, leave that poor bravo alone, it's a nice car in what looks to be good condition, it doesn't deserve to be ruined by ignorance.
 
I will probably leave the engine alone as I asked the opinion of some people that know more about engines than I do, the turbo and intercooler idea have been already ditched.

However I would not call asking questions ignorance, I would be stupid if I just did with no experience or second opinion, asking never hurt anyone :)

no quite right and i apologise if i come across bluntly, but i stand by what i said. A lot of very clever people spent an awful lot of time making that car, and as a beginner, there is NOTHING you can do to improve it, so please stop trying to make it better. concentrate on keeping it alive, learn how you should service it, do oil and filter changes, then move on to other easy service items, have a knowledgeable friend help you change brake pads, learn how to bleed the brake lines properly. etc etc, there are lots of things you can play with to help you learn.
realise this, if you want a fast car, buy a fast car, don't buy a car made to go to the shops in, and try and make it fast. it costs a lot of money (even more if you don't have the skill to do it yourself) this is real life, not gran turismo.

M20B25 is an expert, he makes it sound easy and cheap, its not.

When I put on my merc turbo I spent ages clocking it and making sure it was right. Pipework is also critical, you need a good steady flow to the turbo and a quick drain to the sump.

If I were you I'd be looking at gearbox mounting it and relocating the battery. That way you could have a compound setup very easily and see a near linear driving experience, with turbo to boot.

Coupe intercooler isn't big, I'd be looking for a bigger setup like I pointed out earlier one from a Vivaro van or Mondeo mk3 TDCI could fit the build and fit nicely behind the bumper for a good air flow

However, I'd learn about engines, turbos and pumps first aswell as welding and basic maintenance.... A lot of work is needed for that!
