nice project, looking forward to see the engine spec.

As I wrote earlier, I do have plans for the engine...
It will be a 12A to start with.
Hopefullt I\'ll find a good 84-85 engine core.
I am also going to use 13B 6-port side plates toghether with a T2 middle plate. The side plates have the butterfly type of secondary port, but they are going to be removed. I am going to bridgeport the engine...
The exhaust ports are also going to be a little bigger. :Thumbs-up
Biggest problem to solve will be the water seals, as these are sitting in the sideplates on the 13B and in the rotorhouses on 12A engines.
Double seals is one solutions, or maby to fill on one of them with chemical metal.
I do also plan to have the engine injected, just need to find a intake and a throttlebody at a decent price, as this is going to be a low budget built car.
There is a Microtech LT10 waiting in the garage for this... :rollin
My hope is to reach 250hp with my setup.
I do also have a couple of not complete Autorotor/SRM superchargers in one of my garage shelfs. hopefully I will be able to complete one of them for use in the future.
My future goal is 450rwhp... :3gears-lh

Next step where to make space for the clutch release arm in the firewall.
I do hope I can leave the rest of the tunnel untouched...
I guess that I will have about three millimeters of clearence when I am done.
 
This is how it looked after some work with the hammer.

 

 
I also did some renovation of the mail cylinders for brakes and clutch

 
Shootpenned, painted and polished...
I use Autosol for the polishing of plastic parts and the chrome on the car.
I don\'t know if you can find that in GB??

 
I did the same with the windscreen washer and coolant expension tank...

 
Merry X-mas o you all!

And a Merry Christmas to you:Santa,

Looking forward to this being finished, plus it\'s my favorite color

One of my friends driving a yellow Rx8, and it\'s realy nice in that colour.
But my car will be a little bit brighter yellow than Mazdas colour...

great thread,, nice work,, well done
my only reserve is that you do not mix the pre 1986 with post 1986 engine parts
- the double or missing water seal groove lark is asking for much trouble

if you use the later 13b parts to build a hybrid 12a you will also be up for custom inlet manifold plate

either build a late 13b and be done

or

a hybrid 12a ,, using all later 13b plates ,, but use milled down 13b housings to 12a width
( 5mm off each side )
with custom plate for the inlet
note --
 there is many advantages to this beyond the initial hassle
[ worn edge 13b housings are cheap , you get the good oil pump, nitriding and injector position holes in the primary ]

or

use all pre 1981 parts to build a traditional 12a bridge
( avoiding 6 p plates and the inlet pattern nightmare )
- the disadvantage is 12a housings are hard to find and reserved for competition
,, you need to have the \'special\' code --else you will be told - " NLA "

Any updates on this?

[Arvika]

I have done a few things lately but not much.
Update will come soon!

+1 I like the attention to detail on this build so far! Well done.:Thumbs-up

It has been a long time since last update, but I have done a few more things on the car...
Front bumber looked extremly bad, but I actually managed to save it.
It took me a few hours of hard work, but here is the result!




And a test on the car!

[Arvika]

What I also done is to find a rear axle that will meet my goals at least 500hk.
 I bought a axle for a B1600 pickup on a scrap yard in the middle of Sweden.
 The advantage of this is that it has the correct width from the beginning, it differs only 40mm hub to hub to the original.
 Another fun thing is that there is a dust cover riveted to the hub when picking out the big 6-bolt drums.
 Guess what rivetes pattern is? Well, 4x110 millimeters ... grin
 You just have to drill the holes and bang in the new wheel bolts, jippie!
 These axles are on 8", and the only thing I can find that would be just as strong is the Ford 9".
 But, for shortening... To much hassle that I do not want to bother about now.
The B1600 drive shaft diameter is 30mm, a tough part...

Here is a pick with the B1600 to the left, and FA3TS on the right side.



Another  thing that a like, it is a 30 splined axle. The same as on a never  B2600 4wd diff. And now the best bit... B2600 diff fit straight into the  B1600 housing!
4.44:1 ratio and limited slip  :-)

This is a bad pick, but the difference is huge!


Sand blasted and painted



And finaly for this update...
I found a person in Sweden with lots of brand new OEM parts.
The tank lid is the first thing on the car so far!




Unfortunately, I will not be able to work on the car now for a few months again. On Thursday I\'m going to have surgery on a cervical vertebra that has been mean to me for years ...
 But as soon as I feel fresh enough, I will be off into the garage again!

I forgot this little thing...

As I wrote earlier, I do have plans for the engine...
But i have changed my mind!
It will be using 13B 6-port end plates with T2 middle plate at the  beginning, and I am going to bridgeport the socondary ports. This  toghether with a semi PP should be enough... :-)
The side plates have the butterfly type of secondary port, but they are going to be removed.
The exhaust ports are also going to be a little bigger.

I do also plan to have the engine injected, I have actually bought a  intake (throttlebody) from a Suzuki GSX750R at a decent price, as this  is going to be a low budget built car. 8 injectors built in from the  beginning.   :shock:
