The 'build your own sportscar on a budget' will be the best match.

Yep. Go on the Haynes forum for the latest updates, and to pick up helpful tips on using an MX5 donor.

Hi,
I am using it as a ford build, Zetec engine, Sierra transmission and rear diff, Cortina front uprights etc.
I guess there is no way to join the Haynes forum any more?

There is a register button on the front page which should work? But I found even as a guest I could get to all the important stuff.

Every time I tried, it says registration is disabled.
I first want to make sure that the TMXR has the same dimensions as the book so I have good plans to build too

Haynes is fully sierra based, so using cortina uprights you will be diverging from standard route.
IIRC the TMXR is designed to use MX5 parts.

Hi,
Talon emailed me saying it's the Sierra frame with additional parts to fit Mazda so should be OK to go down the Ford route.
I will be making my own front wishbones so the Cortina uprights should be fine.
CADing the car before build so hence questioning if it's to the Book measurements

Yes it will be to the book measurements. The changes for MX5 gear are on the diff mounting and the wishbone design (and the steering wheel mount). The
rest of it will be as per book.
The book updates can be obtained directly here;

Hi
The standard book spec haynes roadster is based on sierra running gear the cortina front hub geometry are totally different from the sierra so at
least new front wish bones would be required, I don't think the is a design out there for them so you will need to design them.
if your going for the TMRX chassis you should stick with the MX5 running gear and if you want to use sierra running gear use the basic book chassis
mix the two will make unnecessary complicated.
I have a talon book (sierra chassis) with Sierra rear axle and front hubs and a MX5 engine and gear box, the MX5 compatible chassis wasn't an
option when i started my build.
Personally using the MX5 running gear would be a lot simpler also parts are very easy to come by and brake upgrades are cheaper than ford and have you
seen the cost of sierra rear calipers?
The MX5 running gear (diff hubs drive shafts brakes etc) are lighter than the sierra, so a good option could be a Zetec engine with MX5 running gear
or even simpler and 1.6 or 1.8 mx5 with a super charger (have a look and TR
Lane super charger kit) I have GSXR ITB's on my mx5 engine sound great but not as good as a super charger!

And the transmission tunnel due to the offset MX5 diff nose and reinforced diff mount, also the gear box section of the transmission tunnel can be
differant from the book spec chassis on the mx5

Hi ya,
I already have all the engine, diff, transmission etc so didn't want to bin it all and start again.
All the designs I have seen online are either Sierra front hubs or Cortina?
Talon said the Cortina uprights are fine?

If it makes life a lot easier, I would go to Sierre Front uprights. Would that make it easier?

Just for my own interest, I did a quick search on Sierra vs Cortina uprights. Even on here there are lots of very confusing posts about the
subject!!
My own (very humble) opinion is that you would be better off on a road well travelled. So that means Sierra. I'm not saying there's
anything wrong with Cortina, but it's not the sort of complexity you want to add in if there is no significant reason.
I've just had a look at Talon's website, looks like his flat pack chassis is sufficient to build either a Sierra or MX5 version. So I
would go with that, build it according to the Haynes book, and stick with Sierra parts.
Compare that to the TMXR ready built chassis which includes all the MX5 changes that will just cause you headaches. And I can't see a ready
built Sierra chassis on his page.

Hi ya!
My thoughts exactly, flat pack and Sierra up rights.
I guess i would need an adaptor to change from the top mounting strut Sierra to the M18 x 1.5 transit drop long wishbone?
