Welcome to my Project 1275GT Turbo Show Car project section!

This is a private project funded by me and built by me in my spare time.

I welcome any advice, comments and brilliant ideas.

If you want to get in touch with me directly please do so at

You are also very welcome to add a comment at the bottom of the page.

I am attempting to document this build both for myself, for future reference and for anyone else who might be interested.

In late 2016 I bought a 1978 1275GT with most of its good bits missing – like the front grill and engine. The body is not too bad but still requires a fair bit of welding.


There is a whopping great hole in the roof where a sunroof was once fitted and my initial plan was to weld a section back in. The extra roof part to weld the hole came with the car but there are other plans in the pipeline!!

I’ve always dreamt about making a “show car” so why not go all in and build a 1275GT showcar?

Nothing less than a turbo engine would do it, so I immediately begun collecting parts for the project (see the parts list at the top).

As you can see from the list I have already bought two Garret T3 turbo setups, however I was a bit quick of the mark as soon I discovered that a bulk head box modification is required to fit these turbos. This same modification is seen on ERA turbos and they use a Garret T3 turbo. Therefore I have bought a complete G17 manifold setup from Matt at Fusion Fabrications. This setup doesn’t require a bulk head modification and some would argue that the G17 turbo is more efficient that a T3. I also opted to get the cylinder head professionally modified so I have asked Alex at The Car Kitchen to build one for me. Alex is a good sparring partner when discussing engine specs etc.

The last four months of 2016 have been really busy for me so I haven’t spent much time in the workshop and my girlfriend’s British Open is still needing the last few things done to it before its test, so plans are to finish that before starting project 1275GT.

So most of my time at the moment is on Facebook and Ebay being inspired and spending way too much money on shiny bits!
