so if if the 2.4lump is heavyer what about reboring the lighter 1.9 thus making the 1.9 even lighter lol so i get the lightend car and the power.
Well, its possible, but I've never heard of anyone re-boring an Alfa JTD. So you'd be forking out for development and research costs as well.. And with a turbo diesel the capacity of the cylinders isn't whats limiting the power, it is how much air you get in the cylinders. The stock turbo is the limiting factor here, only good for around 190-200bhp. A bigger turbo essentially means you can force in more air, inject more fuel and get more power.
as for the Q2 isnt there a Q4 system for the gt i have seen it on other alfas... <snip> my dram gt would have AWD 2.4 twin turbo deisal that goes well when needed but looks the same as any normal 1 (a sleeper)
money isnt a problem as its being built over time so hit me with your idears on this ect plz dont slate it to much i love the alfa gt and the plans will go ahead
Q4 would be possible, just, with MASSIVE amounts of work. Alfa did a 1.9 JTD Crosswagon in LHD only on the continent. The engine was mounted the same way, but you'd essentially have to buy a CrossWagon from the continent, and import it and use it as a donor car for the gearbox and all the drivetrain and probably suspension components to make it fit.
Unless you can do this yourself you'd have to take it to a race car builder, or somewhere that builds modified/custom vehicles from scratch. AutoDelta might consider it but expect £10K+ in labour. For what it would cost to build a GT with 2.4 JTD twin-turbo and Q4, you could just buy a GT 3.2 V6, get it bored to 3.7 and supercharge it, and have more than enough money to pay for all the extra fuel it would use, and it'd be faster and sound better.
£500 for a Q2, £250 for a good remap, £250 for some better brakes, £1000 on suspension modifications and you'll have yourself a really good JTD that mid-range Scoobies and Evo's would have trouble shaking off. But unless your willing to spend tens of thousands of pounds you're not going to beat them, basically because no-one has ever done it before so you'd be paying for all the research & development as well as the actual work.
