Re: Q4 engine in to 145
There is also a coupe with Integrale running gear on the Fiat Coupe forum. 155Q4 running gear should be a fairly easy swap to a 145, the rear sub frame should go straight on. Also Dedra Integrale running gear is a direct fit (with some minor modifications required) - but good luck trying to find one!
Q4 engine is the same as the coupe 16vt (which is an easy fit). The transfer box I'm not sure on - if anything you might need to drop it for the Coupe final drive, or just get a coupe box.
You'll also need the hubs, brakes and struts as they are all bigger than the standard 145 stuff.
Websites are like ********s, everyone has one, and im wary of any bloke trying to direct people into their's
