Me and a mate have been talkin about removing the 1.4 lump from my mk 3 astra and fitting something bigger in it.

I was just wondering a few things, such as how much should i expect to pay for a 1.8 or 2.0 engine from somewhere. breakers maybe??

Also, what other stuff would i need to do and what else is involved etc?

Are there any sites that would have guides etc to help?
