got a mk2 renault clio 1.2 and want a bigger engine,
what would be the best engine to replace mine with?
Yep, if your going to do it all properly then it really isn't worth the money. I was seriously looking into it on my previous Clio (1.2 16v), even got as far as getting quotes from people like Flux. Ended up buying a LY 182 and I haven't looked back. Glad I spent the money on a Sport rather than throw money at a conversion.
