hi just wondering what header tank you lot have used when you use a r1 radiator with the r1 engine..and does anyone have any photos of the r1 rad in place cheers.just trying to pick up on my build but it has been stood for over three years whilst i slightly modified my house so whilst my better half is happy for now im going to try and crack on with the car.so i will need to move fast because you know what women are like ,,allways haveing good ideas.i think if i could get the engine running that will get me determind to finish it..any help would be great

Can't remember if the R1 rad is curved ? May be a little awkward to fit in, if so. Use a Micra or Polo rad

Here's my old header tank (sorry for the size could be arsed to re-size it)

i have the exact same one as fesycresy

im actualy useing the bike radiator in the car..
