2.4 JTDM vs 1.9 JTDM

Hi all,

You may have read my other thread regarding a planned purchase of a 2.4 JTDM TI. Unfortunately fallin through.

Now im back on the market to find another well priced TI that ticks all the boxes. I have falling in love with the 2.4, but would i be disappointed with the 1.9?

What mechanical things compared to 2.4 issues, would i need to look for in the 1.9?

My wife's is a 200 remapped. In standard form at 200bhp I even consider the 2.4 a bit under powered for the 1800kg that it weighs. I do believe that later cars were lightened but I don't know how much that improves performance. Post 2007 all manual 2.4 cars got a better turbo and 210bhp.

I believe that the 1.9 has a different gearbox (M32?) so may (probably) have different gearing to help or even improve acceleration but I have also seen reports that this gearbox is weaker. If that is correct that box or clutch may not cope well with a remap on a car of this weight.

Most of this info on the 1.9 is reading threads rather than known fact. Hopefully someone who knows facts first hand will be along to confirm.

Best to drive each and see what you think.

I also was contemplating a 1.9 159 before I got the brera. I asked on Facebook what everyone prefers for a mix of power and economy and everyone said get the 2.4. I got told the 2.4 got good mpg on the motorway but since joining this forum people say otherwise lol only time will tell!
