I have spoken to Mark on and off about the Alloy blocks and 25kg saving right there is a huge benefit across the front axle. I like this option for the long stroke and Mark said he can even get me up to about 2.7l but the costs do get pretty big when you add in the crank and head work etc. Based on my engine costs so far I would be close to 20 big ones but you could argue that a good MAD engine of that spec has a good second hand value albeit in a small market should you need to sell up later. My Borg Warner would need to be dumped too on the long stroke as it runs out of puff on the bigger capacity.


The car is my hobby and I enjoy the time on it and the journey building it.


I took my 911 to RSR engineering for its track day set up, he has won the Porsche Cup with Paul Edwards a few times and also ran some cars for Le Mans for the factory team, he blue printed my engine and told me not to bother adding power for the track and stripping the car would give a far bigger impact and 100kg was a huge improvement. I made that saving free of charge too as all I did was remove stuff, the only cost was then to add some Recaro SPG. We found a Heigo cage made of Ally as that was banned from racing but did a good job stiffening up the shell.


I am happy with the route I am going down, others may sniff, doesn't really bother me much.


I only weigh 76kg by the way, I was always quick in a Kart due to being much lighter when I raced them.
