159 - 1.9 JTDM TI v's 2.4 JTDM TI

Hi, currently have a 1.9 JTD GT which will be replaced probably around mid July.

Apart from the 60BHP difference and MPG, does anyone have any other comments on the difference between the two? Specs seem to be the same.

I guess the 1.9 will be a bit more nimble. The brakes will be a bit smaller. Map it to 185bhp and it'll be great.

I agree with SR. I've just had a Steinbauer P-Box fitted to the GT and it's lifted the car's performance in a beautifully subtle way. You'd think it was factory - in fact the engine now feels significantly smoother and the power and torque band higher an broader on the graph make a significant difference to performance. MPG is slighlty better but I suppose it's still too early to be sure on that one. I got 46.6 mpg trvaelling from Dumfries to Durham Tees valley airport. Mixed motorway and A road.

The 2.4 will still be more refined and probably sound better, but I'm convinced the 1.9 JTDM is the best all round engine in Alfa's current line up.

The 1.9 doesn't sound as good as the 2.4, but the power difference is substantial. I agree the 1.9 is probably slightly more nimble, but I doubt you would notice it on the road - the 2.4 is such a great handling car and has huge grunt out of corners and also has a more usable (longer) power band. The new 210 bhp engine is a real belter and is a significant improvememt over the 200 bhp engine (which I have). Unless economy is a big factor the 2.4 is worth the extra money.
