2.2 JTS Spider vs 1.75 TBi Spider

Hi All,

I need some advice. I'm thinking of buying a Spider. I'm considering one of these;

Alfa Romeo Spider 2.2 JTS 2dr ITALIA INDEPENDENT Grey, 2010

Alfa Romeo Spider 1.75 TBi 2dr Black, 2010

I fell in love with the Italia Independent, but had a bad experience with JTS 156 and I've heard lots of bad things about the JTS, particularly the engines. And don't really know anything about the TBi.

Any advice would be greatly appreciated

Kind regards

Faltering Alfa fan

156 JTS and Spider JTS are different engines. The ones in Spider are from GM and are chain driven. My personal preference is naturally aspirated engines and I'd go for a JTS. Lots of people will write TBi is an "Alfa engine" and is better.

2.2 is a better motorway cruiser as it has better at speed acceleration.
It is hesitant at low revs without some tweaking.

1750 is nicer around town and could be seen as more fun,
but is quiet compared to the 2.2.

You need to drive the 2.2 through the gears whereas the 1750
pulls in all gears but does peter out sooner.

I'd personally go for the 1750 if having another 159 or Brera/Spider.

Many thanks for your feedback.

Which is the most reliable of the two, I'll be doing about 80 miles a day in the car?

They've both got their potential issues, cam chain stretching with the 2.2 and a couple of turbo failures with the TBi ; both of these are believed avoidable with more frequent oil changes

Also worth noting that the TBi is eminently more tunable, 240bhp from 500 !

We did 2730 miles to Italy and back in a 2.2JTS Spider in the summer, not one single problem. (apart from breaking the sun visor!)

I did 105k miles in my 2.2 Brera and the only issues were a cam chain and two valve timing solenoids at 95k miles.
I like the 2.2 a lot, it is a nice smooth free revving unit and sounds nice especially with a modified induction. The hesitation is an issue but I believe that a good remap helps a lot.
I have never driven the 1750 but I believe that is more of a mid range power engine than the top end power
2.2 so it depends what type of engine you prefer.

Both Engines are FPT (i.e. Fiat)

JTS has a Holden block. It is not a GM Engine top-to-bottom.


The TBi is quite a little unit. The anti-lag set-up means you get no lag in most situations.
Fuel economy, however, isn't exactly improved by squirting fuel into the cylinder on the outlet stroke to keep the turbo wound up....

That I know . Still, wouldn't call it Fiat engine. I have never driven the JTS, but TBi has no engine sound at all and the fun ends at 5,000 rpm. Which is not so good, especially for a fun car.

Yup, matt paint is the Italia independent. Not to mention what would happen if you scrape the car and need a respray. I can't imagine it to be very cheap.

I have driven the 2.2 and the 1.75 tbi in the 159 and would get the 1.75. Acceleration is faster and you don't need to keep the revs high all the time for it to go. So motorway overtaking is simply the case of depressing the accelerator. In the 2.2 a down shift is required. In addition a tuning box or remap will make it even faster and that's not an option on the 2.2.

There are drivers that actually like changing gears. There's nothing derogatory about it.

That is a load of rubbish, I've never had to down shift to overtake on the motorway. 6th gear can actually take you from 20mph to 130mph. It might take a while mind!

But that's the point, I think

In the 2.2 in 6th at +130kph, if you have to reduce speed due to a car ahead
and then want to quickly get passed them (and back up to your previous cruise speed)
once they move over, you need to drop a cog.

In the 1750 the turbo is wound-up and you just need to step on the gas for similar
acceleration in the same situation.


The big difference is that the person knows you've passed in the 2.2 from the exhaust note.
