And my last 2p’s worth.

your turbo, it looks huge. Isn’t it from a 6L diesel engine. Like the big Holsets ? Hence the external wastegate. What’s the spool and torque curve going to be like ? I am sure it will make the numbers but what will it drive like.

In a mid engine kitcar I would think the last thing you need is large dollops of torque to brake the back end loose. You will be pointing the wrong way on round abouts lol.

I would have thought the tried and tested Gt28 hybrids would be much better suited. Again if You go the Rs route it will all bolt on and have room for the block breather.
