Hi Josh and welcome to Delta ownership and rare car status in most countries! You're quite lucky as in the UK we didn't get the higher spec cars with dual sunroofs or in fact the 1750tbi engine. We only had a choice of the 1.4 multi-air petrol or 1.6/2.0 diesels. The 1750tbi was however available here in Alfa Romeo, and I had one on a 159 Sportwagon back in 2012. The main thing to watch with that engine is oil quality. Also ignore the recommended service intervals and do an oil and filter change a lot more often, circa 9k miles/12 months. Also when doing your regular fluid level checks, have a sniff at the end of the dipstick. Mine ate 2 turbo's in quick succession before the problem was identified as a couple of leaking injectors diluting the oil with petrol - in the latter stages, the contamination got to 8% petrol after only 6 weeks and 2k miles since the previous oil change. Since then it has become apparent that whilst not affecting every 1750 engine, mine was not exactly an isolated case either. I know you said the cambelt has been done, but check that the water pump was changed also, because if not and it seizes it can throw the belt and trash the engine. For gear shifter knobs try Italian eBay... Tyres I use Avon ZV7's at the moment and have just replaced all 4. Here in the UK they were the cheapest mid-range tyre I could find with low noise and good wet grip. I'm on my second set and they've been good value at around £70 a corner. Obviously tyres is an endless subject and everyone will have their own opinion. The car was supplied with Goodyear Eagle F1's and to be honest the Avon's are just as good, but probably won't last as long. Mods... Massive subject, but I'd start with handling too. What wheel size are you running 17'' or 18''? As this will make a difference when you start to lower and stiffen up the suspension. For throttle response have a look at a 'Pedal Box' from companies like DTUK. They're plug 'n' play, and seem to work well. As for exhausts I've not looked at on the shelf systems, so haven't a clue what's available if anything. I've always had systems made on the car in stainless steel, so that maybe the way to go...Lastly most intake systems I've used/seen don't make any gains, just make more induction roar. So my advice would be stick to the standard airbox and just replace the filter with something like a K&N. There's no dedicated area for photo's, just create you own build thread and get posting... We're a bit of the adopted kid syndrome here, as the car clearly isn't a Chrysler, but we have made this little place our home, and seem to get left alone to talk Italian!
