1975 Beta Coupe project QLD Australia

Post by iano » December 13th, 2011, 2:18 pm

Dear All,

I thought it was about time I posted some pictures of my 1975 Beta Coupe which I have been steadily rebuilding/modyfying/competing in, which seems to be transforming from a road car into something more serious....All work performed by myself to date, and has been great fun.

The car has cost less than AU$10000 so far (including initial purchase) and has been competing mainly in hillclimbs, and has proven very successful and reliable, winning the road registered up to 2000cc class in my first year of competition and beating RS2000's, Fiat 124 spider, Alfa GTV, Honda Civic Type R and more! (Much to the annoyance of my fellow competitors who spent much more than the entire cost of my car on their engine alone!)

Hi there Iano,

Thanks for sharing - that is a very clean looking car and a nice install. Good to see these cars campaigned to such good results. Every time I see a Beta Coupe it makes me hanker after my first Lancia!

thank you

Darren

Thanks for the kind comments Darren.

To be honest there have been times when something newer, and/or with rear wheel drive would have been better suited to competition, but I like the challenge, and after all you don't see many Betas on track, especially in Australia!

Latest mods include a strut brace and new coolant header tank.....

Very tidy car.

I can't remember the last time I saw one on the road here.

From the clip, it was well worth all the effort!

Hi
Love your car! I had one much the same a 1975 in red in the early nineties and still regret selling it. Well done you for getting a Beta out there and competing. We have a rather quick one over here in WA, though it is the very last of the models and shares the same grill as your car. There is another 1975 Coupe being developed at the moment but is still some time from hitting the track. Funnily enough it was my Beta which led me to the joys of these wonderful engines and at the time I never imagined I would get into old Fiats the way I have. Great Video.

That is one sweet looking car you have there. I can totally imagine you're holding on to this, even though RWD is tempting.

It has been a while since I posted, but here are a few videos of events last year, first at Lakeside Park racetrack, then Queensland raceway for the Festival of Italian Motorsport, which was great fun, managing 4th place overall against a field of Alfas, Fiats and Ferraris.

MODEL POST!

Nicely described with tech detail and beautifully illustrated from the start.

Particularly pleased to see the sealed intake!

Thanks Ian!

Thanks Guy,

The sealed intake is a must in Queensland as the ambient temperature reaches 35+ degrees C. I measured the intake air with the original offset radiator and the carb was ingesting air at 50+ degrees C!!! In its current location intake air remains at ambient. I also insulated the air box with self adhesive "armaflex" to further prevent heat transfer.
