Tuning Alfa 156 2.0 JTS

My verdict: a nice placebo part wich does not give any power increase but gives you a better sound from your engine which gives you the impression you did gain some power...

my thoughts exactly.
can i ask what year your JTS is? it seems after march/april 2003 alfa corrected the problems on the JTS engine so if it were say 53plate the factory out put should be the full 165bhp and i'd imagine tuning this would give much better gains than you achieved providing yours is a pre 2003 model.

My car is november 02

Do you have some more info for me? Do you know what has been changed in the later models?
I have heard that the inlet cam has been changed, I then assume that cam lobe and timing has been changed. However I recently ordered the camlock tools for the JTS and there is only one model on the market which just perfectly fitted my cars cams.
This would imply that the cam has not changed very much i guess...

F156

i would of thought that there would be very little difference in the cam itself. i was speaking to someone on another forum and they said whilst looking through part number there are modifications up to the suggested dates of the correction.

there are two different engine numbers cant remember what exactly but i know one ends in 1000 and the other in 2000 whether this could indicate the change im not sure. mine is march 03 and ends in 1000 so it could well be the case? i'd assume yours is the same no.

Is there any company producing a carbon rigid pipe for the JTS? Would look nice and help slightly with keeping temperature of the air down too..

Rigid pipe being the pipe directly after the air filter. Also have any JTS owners modified their cold air intake?

losing me a bit.

The 2.0 JTS is a fantastic engine... Superseded only by the V6...

Tuned Alfa engines are awesome, but to do it always costs!

Why would you want a dirty old diesel in an Alfa Romeo... I could never by a diesel Alfa even if it did 0-60 in 2 secs and 10000MPG!!!!

I bet you would

I have grown up with Alfas, the sound of the Alfa exhaust and induction to me is one of the greatest sounds. Diesels just don't do that, plus the stuff stinks you always get it on your hands and feet at the pump and your car ends up smelling like a delivery van after a few years!

Alza2000 - I like you fella. You talk my kind of engine sense

yep a real Alfa is a petrol Alfa...

cant believe people consider diesel ones! next they will be insisting Alfa build an MPV or a 4x4... hey why not a van? ;-)

I still have fond memories of the first time I heard an Alfa V6 start up and drive off probably about 1981 that was when I knew I wanted a GTV6... who can forget the old flat four in the Alfasud... sounded great and you only had to touch the throttle and the thing was off... I don't think I have ever driven a car that was so responsive to the throttle as an Alfasud, and you could rev it so hard... not like the hard work yawn inspiring diesel engines... I like to hear my engines screaming toward the red line... not doing an impersonation of someone ploughing a field!

If I were to tune the JTS engine I think I would be looking at the complete unit maybe have the bottom end lightened and balanced. Head gas flowed etc... new cams and induction kit, remap, I would aim to get more revs out of it an make it more responsive. You should be able to get 200BHP quite easily, but not necessarily cheaply!

Well, I don't have any fond memories, I'm coming at this dilemma completely unbiased, as I grew up being a passenger in (really old) Jag XJ, BMW 7, a Daimler, etc, the first Alfa I drove was a 156 JTD and although I since have bought a V6 and prefer it, I still think the JTD suited the car down to the ground, just for slightly different reasons than the V6 does. I think the 2.4 JTD would suit the 166 even more so, it is a powerful, responsive (yes, throttle response post-remap is better than a lot of petrols I've drove), rev-happy and seriously torquey. The 2.4 JTD is definitely the 'touring' engine, and the V6s are more for performance and racing, for mundane day to day driving I'd be swayed by the JTD, and they do sound nice in their own way (except at idle)..

Will do the V6 GT when oil next needs topping up.

Benefits are more mpg (seriously), smoother & more free revving.

I think it's the real deal

(sorry for hijack)

Ever get round to trying it in the V6 GT? If so, were the results as expected?

i wouldn't waste your money, seriously a decent oil will have similar properties. if you put 1/2 a litre in of that then you've got 1/2 a litre less oil?!

its more for industry where friction occurs between non-lubed parts. you engine should have oil doing the job.
remember the castrol advert years ago? it showed the molecules sticking to the parts of the engine to stop engine wear at start up?

but then i am a skeptic
