I'm doing a ford. Hold so may be wrong but there can be loads. Carpets, clocks if not donor ones, all fixings and fittings, brake pipes, new pads and discs as req'd etc

I got a full list off GBS of every single piece I'd need, I'm sure there is a Mazda version too.

Unfortunately this is not a straight forward question to answer.

Why?

A lot of the kit build experience is tied up with what you are wanting or expecting as the end result. Are you building and then enjoying using it, or are you going to build and rebuild. is it a prestige thing, I have this bell and this whistle, or will it end up sitting in the garage as you were embarrassed to park it next to other cars.

I have been around this and many other forums for a few years now, and questions like this will bring you a lot of very well meaning advise. Some very good, all well intended, but all based on what the contributor felt was the best way to build the kit.

My advise would be talk to GBS if you haven't already, it is not in their interest to allow a builder to launch into a project without a clear understanding of what is to come. I believe they are realistic at stating the true cost of a build if your target is a result similar to a vehicle from the factory. There are other ways of achieving a workable car, and a know of a few that have decided to re use wiring looms, or build there own, re utilise the donor ECU, etc, whether they felt is was a good idea later into the build, I am not so sure.

If you have a technical question or want a better understanding of motor vehicle in general, I will try and help. but unfortunately on your original question I must pass.

IThere are not many parts from the Mazda that you can use engine gearbox diff hubs drive shafts steering column.keep all the engine connectors as you will need thes
To connect to the GBS look .

have been building my Mazda engine Zero for the last 3 years buying parts as I save up.This is certainly the most expensive way of doing it but for me otherwise I would never ever have started.If you can buy the full kit from GBS then do that.Important choose engine carefully and if you have a later one ensure you ask GBS for the modified frame so you can use the Mazda inlet system.Otherwise you have to have throttle bodies which is an extra 1K
There are loads of options that you need to think about .
1/ the donor ,buy a second hand car and strip it refurbish bits sell what you don't need .(recommend buy best you can and run it for few weeks)
Or buy a package - GBS have some and some Mazda breakers will sell you a kit .
Depends on how good/fussy/affluent you are - I thought I was being clever buying a MOT failure and making money on it after selling parts but was not happy with the brakes once stripped so ended up buying new ones.
2/Yo do reuse the prop shaft steering column and drive shafts but these all need altering and there is a cost there.
3/decide whether you want narrow or wide body cobra hoops ,stainless or alloy if latter you will need to factor in paint or wrap
4/wheels and tyres - Mazda ones do not fit.( Unless you use spacers)
5/ Wiring - unless you are a masochist or very patient buy GBS p and P loom best thing I did
6/ what are using car for ,think about wind screen weather gear.
7/talk to GBS ,look at blogs but be careful not all of them are correct

Enter with your eyes wide open realise you are going to spend a lot of money that you will not get back view it as a hobby that you will enjoy a lot more than playing golf or drinking at the pub every night.
And you will at the end have a high performance sports car that you can tell everyone that you built

Having just completed a Mazda build, I can certainly vouch for how much you can spend if you really want to! I started with best intentions budget wise, but scope creep happened almost from day one, some of it through naivety and some of it through active choices! I thought I was well prepared beforehand, but it turns out I wasn't!!

1. Best advice I can give is stick to a pre-2001 donor as the later VVT engine variant throws up some problems that complicate things and can cost money to get around.
2. Speak to the factory a lot, the car has been developed a lot over the last few years so even the good blogs are out of date in some areas the moment they're written.
3. Always ask about fittings for any part you buy from GBS, sometimes they're included but often not so you waste time then ordering some bolts you need!
4. I'd suggest asking for the chassis mod to allow the Mazda inlet manifold to fit regardless. You might start now with an engine that fits, but what happens when you upgrade it in 5yrs time?!
5. The donor loom and ECU can be reused, but you'll have a lot of excess to remove to make it tidy. The P&P looms from GBS are great, but come at a cost. Retrofitting them would be a major undertaking! The original ECU cannot be reprogrammed so you'll running OEM power.
6. Kitspares isn't the only supplier for parts, sometimes its worth shopping about. Something like the popular Smiths Flight gauges with in built warning lights are only available from them though, but this isn't always obvious!
7. You don't get a lot of parts you can actually build with in the starter pack, it's mostly just the big bulky items! Expect to spend at least double to get to a rolling chassis.
8. Everyone will have an opinion on something, but it's mostly their opinion! Rolls Royce make cars differently from Audi, doesn't mean either them are wrong in how they do something! There's many ways to skin a cat which explains why there's so many different cars out there. In my opinion its good to listen to advice, apply some logic, then decide how to proceed. If it works and if it's safe you're car building!
9. There's no such thing as a silly question. Ask if you're unsure on something, it can save excessive head scratching and costly mistakes!
10. And finally, welcome to this crazy little world!!

Hi Gary
I've not long started my mazda build. I went for the GT chassis with the USA mod as im using a 1.8 engine and that way the plenum chamber won't catch on the chassis cross brace, also I won't have to use throttle bodies.
My donor was a 2000 1.8 s which has LSD and sport seats that fit in the GT chassis.
So far I've reused
Calipers refurb
Clocks
Washer bottle
Indicator/ light stalks
Brake m/c
Clutch m/c
Clutch slave cylinder
Seat runners - modify
Various bolts and brackets
Steering colum shroud
Drive shafts - modify
Prop shaft - modify
Steering colum - modify
Hoping to use
Ecu
Wiring loom
Radiatom header tank
Hazard light switch
Dash light dimmer switch.
A lot can be used but with modification.
Have a look at my blog and you'll get an idea as to where I'm at so far.

Some good replies here - thanks chaps.

Does anyone have picture of the chassis mod to take the 1.8? Be interesting to see.

@michaelhopps - I see you're in Cannock too!

The newest chassis do not have the rails going through the engine bay. They have reconfigured the rails to go around the upper, outer edge alleviating the Mazda air box issue.

there is a third mod,

are you sure the "new" mod is not for the V8 engine, because it would make more sense.

Thanks guys - can see the difference now.
Are all the new Mazda chassis like that or do you have to request it?

Some good looking blogs too!

The mod is known as " USA mod " and there is a cost implication of approx £200.
No, I'm not fitting a V8 just a 1.8 from donor with oem plenum. I like the idea of the bracing being mirrored as it will create space for a turbo in the future if I so desire.
