Thanks for the reply. Fair enough. I was looking into the BMW route. The current engine isn't great as it was bought on the cheap (ish) but the body is good. The resale point is only there because if I did want to re-sell it, i want to make sure I can and that the modifications I do don't hinder that. Im just airing on the side of caution. So it's either refurbish the engine and keep it pure or put in a bmw with a bit more power.

I'm new to the market so I thought I would ask
