Ah nice, do enjoy the mods!I am new to this forum.... I have also just bought a GP 1.9 Mjet Sporting 130 ( 2006) with 78,000 miles on it.
I bought it as a second car to commute 350 miles a week on motorways etc. My main car is an Alfa 156 1.9 JTDM 150 remapped to about 190.
One of the main reasons for buying the car was the engine, as its basically the same as my Alfa, although 8v as opposed to 16v, and I know they are very good power units.
I am considering maybe remapping the Fiat at a later date, but the 6 speed box is a weak spot on these cars due to the power/design flaws with the gearbox bearings etc.
In fact it is quite noisy in all gears so it will need attention at some point !
Being new to Fiats ( this is my first !) I have been very impressed with the way it drives, the 6 speed box is so good to use ( its a better change than my Alfa ). I have already done over 1200 miles in it in less than a month !
Apologies for going OT on this thread by the way !
Re the OP wanting to mod his car: I would do the same if I were him, but I would be wary of a remap due to the above issues re the 6 speed box: I have spoken to a Fiat specialist and the OEM bearings in the box are too small and wear out. I also asked about maybe getting a higher 6th gear put in when I get the box refurbished, but apparently that is not possible. I would like the higher final gear to give me more mpg on the motorway...
I've read the same about the box (yours I believe is the M32 - aka CHOCOLATE!) however those found in the Tjet models are a 5 speed, a far more reliable and stronger platform, but still not the best. I don't seem to have any issues with mine, but I'm driving it pretty nice and avoiding heavy acceleration in 1st etc. If it needs a rebuild I'll be doing the clutch slave cylinder, stronger parts and a more durable clutch. Costly... Let's hope it won't be needed!
