Can't argue with that fella!
Although a performance exhaust and decent induction kit would definitely make it sing better!
Anyway back on topic... Having owned both a 2009 Brera and Spider 2.4 with the latter being... lets say tweaked!
2.4 vs tbi...
In standard form, they're a good engine with a nice amount of torque, and reasonable acceleration. However a 2.4 free'd of all inhibitions and mapped is a totally different prospect and =
a Mahoosive addictive grin, you'd love especially the in 3rd gear accelleration which is amazing, and a nice 5 pot burble at full chat, they give good mpg (late 30's/early 40's on a run, although admittedly not great for a diesel on first glance, but given the power/torque and being a 5 pot I think actually not bad at all)... overall a great engine with lots of potential and mega miles capability!
The 2.4 is a bit nose heavy on the limits, could be problematic if only driven only in stop/start low miles suburbia situations as has been covered many times on this forum. They stopped making it in May 2009, although there are a handful of 59/10 plates available if you're patient.
1750 tbi Positives:
Very little known faults reported with the tbi so far, so should be a good long term option regardless of driving habits (Urban vs Motorway). Good sound track for a standard set-up and rev's freely. As stated in above posts highly tuneable circa 190bhp! With a motorsport 200 cell Cat and full performance exhaust and a decent induction kit this could sound amazing!
The engine is under powered in standard guise with the 159 being a fairly heavy car. (My opinion) So you end up driving it hard to get the best out of it. Fuel consumption could be better giving late 20's early 30's. Not worth as much come resale time in like for like spec/year etc as a diesel.
I'm at the same point considering both a tbi or another 2.4... 290bhp tbi is very tempting, but if a very late low miles 2.4 comes up at the right price it could go the other way
