CTC Performance ZC31S Demo Car

For those who have been with us for many years you will know we bought a 2010 Swift Sport in 2011, she was 12 months old but in a bad way having been in a front and rear end accident. We bought her with big plans. We focused on handling adding lots of braces, cage, brake upgrades and repaired the damage finishing her in a controversial Kawasaki Green (yes it’s actually Kawasaki paint..) then we went racing in 2012 in the Nippon Challenge. Had some success but mostly frustration. While we could qualify with cars with 300hp in the race it was nearly impossible. We lost 5-10 places off the start to rear or 4x4 cars, they then hold you back in the corners where the Swift shines and then pull away on the straights. To fix this we decided we neeed less weight, more power (200+hp), a differential and shorter ratio gearbox. We have spent many thousand pounds trying to build a M20A 1974cc engine however after 3 engine builds we realised the coolant and oil mixing was a result of the plonkers who fitted the liners not fitting them correctly so they leak once up to Temp. Now being non the wiser if the 3 different gaskets we tried work or not we have opted for 1900cc so got new pistons made and a whole new block and liners. It will be finished in 2019 for sure we have been a little distracted with the ZC33S development but this thing will be on track this year so watch this space. I’m not going to post the full build but here are a couple of pics to start.

I really do hope its out this year!

This is the car that made me choose a Swift for sprints.


Any pictures of the rear of the car?

This is my favorite one of the rear in its later guise.

So we have some news on the Green Machine... so from the first pic you can see just how long she has sat! Look at that dust!! First up we had to remove the M16A engine

We then fitted some new pads to our BBK as we had removed to send to SonicRacingUK.

Next up we cut a massive hole over the fuel tank, we have done this so we can install a removable plate so we can access the fuel pump without dropping the tank.

Then comes the interesting updates, the building of the M19A!

Just need to clean up the gearbox, fit a bulkhead fitting for my race heater, do some wiring, sort passenger seat mount, cut plate for over fuel tank and install the engine. Engine will go in tomorrow all being well....

Awesome, and that shifter looking sexy! Did you design that yourself?

Nope but we are selling them for 31S and working with the manufacturer to design one for the 32/33S

I really like the shifter. If i didn't have a cae shifter would definitely bought one.

I'm looking forward to the pictures of it mounted to the car.
