Greetings list members,
I am a new member and this is my first post. I am new to Alfa’s and I am currently in the market for 1969-1974 GTV.
I have a question about parts compatibility between the 105 series GTV and the Spider cars, specifically the 1980’s Spider models (Series 3). I am wondering if a Spider would be a good donor for modern/improved parts for the GTV.

  • Can the Bosch EFI motors be retrofitted?
  • How about the suspension or driveline components?
  • How about the steering rack? I would assume a late ‘80’s car would had rack-n-pinion
  • Are the wheels the same bolt patterns?
Thanks in advance!
Mike

* Bosch engine can be fitted but it requires some knowledge of hooking up the computer, sensors and where to put the ECU, AFM, etc. Some fuel system changes required. Folks have done it, but it's not a weekend job for the inexperienced.
* Suspension, brakes, trans, diff all identical other than springs, which will be a different length and rate, though they'll fit. Driveshaft and e-brake cable are different lengths.
* No rack, they have steering box. It'll fit and work unless the Spider has PS. Steering column length and details may different if it's a very late SPider.
* Yes, wheels are same.

Not meant as an insult, but if you're asking these kinds of questions I'm guessing you may not be a candidate to do this kind of work yourself? Unless you're experienced on other marques and just new to Alfas...

Andrew, thanks for your concern. I'm sure there is a ton of stuff specific to Alfa's that I don't know. I didnt want to sounds assuming in my post.

But I guess I should have prefaced my questions with some of my technical skills. I have some experience repairing/rebuilding/upgrading suspensions, braking systems, engine mechanical intake and exhaust systems, driveline and differentials parts. I also have a quite a bit of experience with various EFI systems, including one very cool project of converting Bosch CIS to a fully electornic EFI using wideband 02 sensors, Mass Air, and aftermarket engine management. Nearly all of my experience has been with the 9 Audi's I have owned including the restoration of two very cool Audi Turbo Quatto Coupes.

I realize that Audi's are a very different breed than anything Italian and the vintage I worked on was much newer that the Alfa's I am considering. I don't know anything about the Alfa line or it's model compatibility or with others like Lancia and Fiat. So I am eager to begin the learning process, and ready to recognize which projects are best left to the professionals!

Thanks again for you help
