Doesnt the injection tank have the swirl pot
would a cavalier 2.0l rad and fan fit into the nova?

1.2 rads are the same size/capacity as the gte's/ gsi's.
Only 1.0's are smaller and need changing.
Wouldnt have thought a cav rad would fit, just stick with the 1.2 one.

gte rad is slightly bigger

According to a radiator supplier I tried a while back they have two sizes one for 1.0 and one for a 1.2-1.6.
Im running a 1.6 on its original 1.2 radiator and its fine, never overheats.

Yep nova GSi/GTE/SRi tanks have swirl pots to prevnet fuel surge whilst heavy corner or braking. It basiclly there to keep fuel pumping up the lines with out a dry spot. The GSi/GTE/SRi rads are the same all the rest of are differnt, im not saying there is a right or a wrong one its your call.
