Here is a quick update for you guys on the Need for Speed D-Mac '86. Our mock up exhaust manifold has been sent to Martelius exhausts in Finland along with our front and rear coolant pipes to be ceramic coated. Here is a shot of the new Martelius manifold being welded in Finland.


And here is the finished product. I think you'll agree they have done a great job and the new manifold will be at MCNSPORT HQ very shortly for final fitment.


As mentioned above Martelius offer a ceramic coating service. The two treatments we will be using on the D-Mac '86 are a 'Thermal Barrier' and a 'dispersant'. The manifold and eventually the turbine housing of the Owens Developments turbo will be coated with the 'Thermal Barrier' which not only lowers the under bonnet temperatures but also prevents the loss of energy from the exhaust gases to the manifold and housing through heat absorption. The second 'dispersant' treatment will be applied to the intercooler and inlet manifold etc and this actually improves the metals ability to disperse heat and should lead to much cooler intake temps. The coolant pipes will also get coated, the hot pipe from the engine to the radiator with a 'thermal barrier' and the cold pipe from the radiator to the engine with the 'dispersant'


While the chassis was being painted, it gave us a chance to prep the motor and transmission for final fitment. For me no engine compares to rotary when at this stage. The contrasting colours of irons and rotor housings is just so cool!! We were working pretty hard as you can see from all the abandoned spanners ! LOL!


Here we are at paint. Every process of this build is done in house so this is in my make shift spray booth in the corner of the shop. Thats is Dan in the back round who does all the painting here. The underneath of the car resembles swiss cheese from all the drilling of spot welds holding brackets that we deemed unnecessary.


With the underneath painted its was time to flip it over and paint inside and under the bonnet. Feels great to get to this stage and get all the fab work done and now when something gets bolted on it can actually be tightened and wont be coming off again, hopefully for a long time.

It is indeed

It is indeed

Savage, much work to get them matched up??.... What ya do use a r154 disc in the 13b pressure plate??....did ya do any bridge porting to the rotor housings??

A bit of work alright, a good friend took care of it for us. Supra bellhousing was machined down to the correct depth and a alu plate was welded onto it. Then the bolt pattern for the RX7 bellhousing was drilled into the plate, then tapped so it bolts straight on

Carbonetic took care of the clutch, using a Twin plate carbon RX7 clutch kit with a Supra centre hub

The engine is bridgeported yes

Fair play man, a real frankenstein machine!!......a man of me heart

Okay, the Need for Speed D-Mac '86 is back to its build bay in the shop which is getting more and more untidy as the weeks go on! Hopefully it should come together quickly and we can tidy up round here. You might notice the front tube extension has not been painted. This is because at the time the car was going for paint we did not have the intercooler and could not make the brackets to hold it in place and also the brackets for the bumper bar need to be made and we need all the aero on for that part of the build.

It looks so much better with paint on it!



We have to do our best not to scratch it while installing all our interior bits. In the next update the interior should be completed all going to plan.



This is the last shot of the rear interior before the view gets obscured by our custom radiator, piping and roof vent.



The rear axle is now painted and located with our 4 link system. It's hard to beat black and white.



Our custom top link is now installed. This should allow us to fine tune our setup quickly on track, not like the original two upper links that are very awkward to access. You can see the BOSCH pump and bullet filter installed ready to be covered by the fuel cell.



The tunnel and bulkhead were just second to the steering in the time consumption stakes but now theyOur MCN/AVO rear coilovers are ready to transmit more power to the tarmac than any other AE86 drift car in history. We wanted to run standard and just off the shelf AE86 suspension rather than a custom trick suspension setup just so we can prove just how good our '86 suspension is.



Likewise at the front. We are using the MCN/AVO adjustable front inserts inside the original struts with weld on coilover conversion tubes.



This has been the most head wrecking part of the build, the custom steering. I hate and love this steering rack in equal measure. It took quite a large amount of time to get everything working the way we wanted it to, but if it all works out it should perform really well.



We made a custom steering column so we could throw away the over complicated Toyota one. A new gear lever has been made for the Supra transmission and we modified the 16 inch ASD vertical e-brake lever to just the right position for me.

Right so, that is it for now, time to get back to work. It should start to come together pretty quickly now. I cannot wait to here the first brap from this thing!

Wow!!! now thats a tidy piece of work! the e-brake is brilliant really is the best angle to have it at!

Serious machine , power to weight ratio of the scales
