Epic. Always been attracted to the idea of a NA high output M42. Keeps the weight down up front.

Would love to hear the story of how you went about building the engine!

I could really do with that sort of power in my car. Thankfully the regs don't allow engine modifications such as this.

the engine is now in the e30 but i did not have time to fit the exhaust as it is going to be a lot of work to get the manifold to miss the steering column. Down on power from where it was but still flying

Good to see the engine put to use. Must be one nimble race car with that light weight nose.
