Hi all, have UN1/1UZfe looking at upgrading UN1 for higher horespower. Know its probably been asked before but which is best way to go. Albins in OZ, GTO Racing Kit UK or i believe that Bruce in NZ (rambolambo) had a local guy in Whangarei that did primary upgrade plus 1st/2nd etc etc. I am based in NZ and open to suggestions. Have heard that the UN1 done properly is as good as ZF?. I have space limitations so have to stay with UN1. Would appreciate any comments. Cheers Jeff
