wepr kit bud..they've got bigger runners than zisco,stay away from race tech very exspensive and i've seen a few of those mani's crack(granted ricky will sort them..but bloody exspensive!!..i'm running a wepr sr mild steel mani,been on 21/2 years no problems yet)
Hi turboloon . about the runners not always the bigger is the better . and it depends on type of engine you have .. we are still running the same type of manifolds that buy on all most all cars an are running in low 11sec ... but if you want it bigger runners tell zisco and he will do it for you..
