rebuilding 912 engine
 

So I'm getting the parts together for a rebuild on a 69 912 and need some input from others who have been through this.
I have a good block and crank(mag and checked, std std) but I have been confused by the next step of purchasing pistons and cylinders.
Big bore verses std kit, how much of of a difference is there going to be by increasing displacement by this option? Should I consider a warm cam?
When I go forward are there any other modifications that I should consider that would make noticable HP gains.
So the next question is Quality, I have seen Big bore on Samba and Ebay for various prices. NLA offers a set decent price. Any comments on vender vs quality?

I'm not looking to spend big money but I just want a streetable engine with maybe a little punch,

Thanks for any advise

I have just installed Brad's set and they are very good for the price. Warm cams are good but a little jerky for daily driver use. If its a weekender then go for it. Don't forget to re-jet the carb's to match the big bore.

Make sure you check the diff carrier - it seems to struggle with the 100hp and often fails (as I have just found out!)

Thanks Rols, are you running a mild cam with Solex.
Do you think your car is running about 100 hp?
Any other mods?
Which set of big bore the cast or forged?

thanks
