Alfa Nord engine
Discussion
Going to try this post here as the Alfa forum is very very quiet.
My Alfa Spider has been in and out of the garage all year with overheating problems and whatnot, which understandably has been rubbish as I have not been able to drive her a huge amount this summer. frown
The mechanic has now had some time to run some diagnostics on her. It turns out that the "new and tested" engine that was fitted to the car last year by a different garage was actually a totally knackered old thing. After the head gasket being replaced a compression test was run and the cylinders are losing roughly 70%. So a rebore and whole engine rebuild is on the cards.
Since the whole engine is going to be getting rebuilt I have asked for some fast road goodies to be added into the mix.
So getting to the crux of my question, how much power can be extracted reliably from the 2l nord engine while running on electronic ignition and twin carbs? Am I dreaming if I am expecting 150bhp or more? What kinds of things should be getting done to the engine? An overbore is going to be occurring anyway and what else should I be looking at for the bottom end?
Cheers in advance to anyone with more knowledge of these things than me.

Thanks for all the replies folks. So I am not really looking at mad power gains from keeping the original engine. I don't think I will be going down the engine swap route, I just wanted to take advantage of an engine rebuild to try to make it a little more pokey.
