Thanks for that info, buddy. :)
You people are great.
I've emailed him and he quickly replied, what luck! :D
As soon as I have my project running I'll post some pics. ;)

Hi there, Datsun lovers!
I'm Bruno, a 22 y/o team leader from Portugal.
I have a black 1985 Corolla GT (AE86) and soon a 2 door Datsun B110.

So my question goes for this:

I have recently swapped my original 4A-GE bluetop with a rebuilt redtop so the bluetop is left alone, I want to use it on the future B110.
Is there any information online I could use to help myself doing this swap?
I know some people have done it but I can't find anything about it... :(
Can you people help me out?
I would be so apreciated.

To finish this post, I must say this is a really cool forum.
Never thought there would be this kind of enthusiasm over the Sunny. :)
