Engine Conversion - Help needed

[Skeeny]

I have a Nova 1.5td and i'm thinking about putting a redtop in. Would this be a very easy conversion, or am I better going for something else?

1.7TD would be best.

the 1.5's are easy to tune tho.

[let_nova]

the 1.7td is also easy.

Thanks guys, would it make it much quicker if I just tune it? What would I need to do?
