Cheers to Mike from Pitstop Massey for being a all round GC!

That oil cap will get super hot (I have a metal one too and sometimes forget :oops:)

Looking good though. How easy was it to wire the coils up?

Started Working on the brakes for the my MX5, Obviously when upgrading the HP potential of the car we also need to upgrade the supporting items as well such as brakes, shocks and wheels and tyres.

As for the brakes I choose a set of 282mm Disc rotors which I re-drilled from 4x114.3 to 4x100

Image

Image

Image

After that I set the mill up to do the slots in the rotors used a ball nose cutter.

Image

Image

Image

Overall I'm pretty happy with how they turned out, next I will make a set of billet adapter brackets to suit a set of Big Wilwood 4pot Dynapro calipers. These should pull the car up pretty quick and be pretty effective on the strip and the track.

Image

I have also just placed an order with Autokonexion for a set Version 1 Flares so cant wait to get them on and then we will be respraying the entire car.

Image

also picked these up a little while ago, they're Fortune Auto 500 series coil-overs which should provide plenty of support on the strip and track.

Image

Basically finalized how I want the car to look or the kind of style I'm going for. Its a little different but I like to be outside of the box.

Image

Image

Image


So thats where I up to at this stage
:D :D

Gave Ben a hand to make a frame, so we can wheel the MX5 around while we work on it, and work under it etc.

Didn't get a finished photo of the frame we made, but there's some things that need adjusting so I'll grab a shot when I get the chance.

Chur Ben! It's coming together.

This evening we test fit a Wilwood kit Ben has in the making, on my car.

The goods, packaged with quality rotors.

After a wrestle with a brake shield, they fit!

Thanks Ben, I was honoured to test these on my car.

Sooo Time for an Update!

Over the last 5 months the body was completely stripped and we began to seam weld the chassis in its entirety, we choose to do this for added chassis strength and the car was getting repainted as well so what the hell!

Before-
Image

After-
Image

Some of the Seam welding-
Image

Also whiles I had the engine out decided to remove the little humps for easier access under the ITBs
Image

More Seam welding-
Image

Test fitted the Autokonnection Flares with the Rays Gram-lites I picked up off MADKIWI
Image

Image

More Seam welding....
Image


Finally after all of the seam welding front to back I have got some etch primer down! Nice to have it back to a solid colour.

Also this month we have been working pretty flat out on the Intake side of things with a brand new Individual throttle body (ITB's) Adapter from Techno Toy Tuning in California. Along with being forced induction we have really put a lot of though into the plenum and Chamber.


Due to the lack of room on the Intake side Designed a two piece plenum system the bolts on to the ITB's and seals using O-rings to eliminate the need for expensive gaskets also the o-rings provide a perfect seals under high boost applications.

Here's a few pictures of so far....

I would also like to thank a few people for their continuing help and support on this build, Thanks to 2LOW2C , Donovan and Sprsta for answering my endless question which at times are rather Running simple! Thank you to Cordedbowl and Furai for always dropping by to give a hand when you can! You legends help keep the dream alive!



More to come! :D

it would be cool if you could get adaptor brackets to bolt up common 4 pot alloy calipers from a road car on to the mx....just saying.... :)

We looked into that prior to choosing a Wilwood Caliper, problem is the Nissan and Rx7 four pot calipers are just too wide without changing the OEM brake tophat height offset drastically even then your lucky if you can squeeze them in!

Mk3 Golfs - The non GTI/VR6 versions come with 256mm rotors on the front with 4x100 and tend to run stock offsets very similar to the MX5, but I imagine they're a different headache due to being made for FWD?

the guys in the states use the 11" VW 89-91 Corrado rotors but they are getting hard to find now

The 280mm? Plenty of those around if you go 5x100, I had a set of 282's on my Mk3 GTI. You'd feel tingles when you stood on the brake pedal.

Nice progress.. 8)

It seems to have a similar look to mine,

Image

even the rocker cover is a similar texture..

Sorry - back on topic, but we must have similar taste in modding MX5's...

driveline wise it's great plenty of torque to pull away in 6th, it's showing ~6psi at 2300rpm on base boost pressure..
the gearbox which now doesn't have a horrid dual mass flywheel does probably make a bit more noise than it would have when it was in a nissan but we can live with that..


Handling wise it's only had an eyeball alignment and I have not touched the dampers, I was more interested in getting the rings bedded in and making sure the engine feels some boost early on.. So initial impressions are it feels reasonably firm, but i have not thrown it into a corne yet..

Oh it'll take a 4500rpm launch without smoking the 225 R888's on the rear.

Anyway back to your project.. what size front disc have you managed to sneak in there? we are for 280-290mm but with a new knuckle to go 4x114 and a bigger stub.

Your Car sounds very promising! Should be a very quick car! What are you mainly going to use your one for?

We currently Have 282mm Discs up front that we have re-drilled 4x100 so they should in effect just bolt on to your existing set up all you would have to do is tweak the Caliper adapter offset and use the same adapter as I have designed.

If you need any info just drop me a PM. :)

Who Did your Catch can setup?
