Hello: My name is Dan and I have been lurking on this board for quite some time. I am near completion on my build of a GBS Zero GT kit from Great British Sports Cars in the UK. While GBS is kinda unknown Stateside (so far), they are fairly big in the UK. Apparently they sprang up from the old Robin Hood builders, but the Zero is different. From what I can see, my car is very similar to the Haynes car in general layout.
Mine uses Miata bits for the diff, rear uprights, spindles, brakes and I choose the Miata 1.8 engine and trans. My goal is to build a very traditional 'old school' appearing car with modern innards. No carbon fiber, digital dash or 20" wheels, just the basics. Nothing wrong with those things, but I still wear a hand wound wrist watch.
This forum has been a huge help with the build. I'll post some pictures, as soon as I figure out how.

:lurking: We'll wait right here- just not very patiently! Glad to have you on- even with Limey kit (CC was some kind of Brit wasn't he?). Just funning ya- any time we get to see some differing solutions to the 1001 problems in one of these projects is a good thing. Bring it! Also believe there is tutorial in lower down part of forum contents page. Past that I'm going to let the genius admin types who keep this playground functional do what they do best (and b the way thank them for running this midnight daycare center for run amok project mavens!)

Here is a recent picture of the Zero. Image The protective film is still on parts of the body panels, hence the white. I am planning on leaving the car with the mill finish on the alloy panels. My zero has aluminum panels. Stainless panels were an option, but I like the old school look. Here is a pic of the engineImage It is an early 1.8 Miata JDM Miata with a Ford Escort GT cam cover and Borla TWM ITB set up. It really makes the BP series look like a Kent based Twin Cam.

Welcome Dan! I hope you've met some of the other builders in the area. There are several active or fairly complete builds in the north San Diego County area. Get some pictures up!

Ok, I think I have pic posting figured out,


The body is aluminum, mill finish, with most of the protective film still on. Hood is going to get louvers, but not right away.


Under the bonnet is a '97 Miata JDM 1.8 pretending to be a Ford with a '91 Escort GT cam cover. All stock except for the Borla TWM 45mm ITB's and a Fidenza light flywheel. Oh, also went with LS6 style coils and converted to direct fire spark.I'm using a Haltech Sprint 500 ECU with the WB1 wideband o2 unit. Just finished creating the base map last night, all systems have been tested, but have not got up the nerve (or time) to try to fire it up yet.

Here is a link to a few more pictures. I have been really slow about setting anything up about my build, so now I have started, finally. I hope to get the car out of the garage and into the sunlight and break out the good camera for some real photos.

And ITBs... <cough>

The "modern innards" part of the project covers the ITB choice.
Really wanted side draft Webers, but after remembering the last half dozen cars I did with them almost 35 years ago, I decided the ITBs were probably way less frustrating and more reliable to boot.

I had a chance to get a complete, big valve, Weber head Twin Cam with Trans, but just could not justify the expense.

Besides, the ITB's reminded me of the coolest real Seven I have ever seen, which had a mechanically injected, dry sumped Cosworth engine. Don't remember what it came out of, but the cars owner was somehow connected to Cosworth in the UK at one time. It belonged to a regular customer of an auto parts store I worked in during college. This guy used it as a daily driver, which was pretty amazing. It was kinda funny, as his other driver was a real MKI Lotus Cortina. Always wondered where those cars ended up.
