Hey guys I have just brought some n1 turbos for my r33 gtr. This is my spec that I have at the moment. cp forged pistons 86.5mm ,cosworth head gasket,nismo oil restrictors, n1 oil pump, n1 water pump,uprated valve stem seals,new lambo sensors,stainless steel turbo headers, elbows full stainless exhaust,hks hard pipe kit,engine bored out 86.5mm, head cleaned and refaced,ohlin coilovers, hks turbo timer,hks electronic boost controller,new super cool 52mm radiator. I also have 550 injectors sitting waiting to go in as well once its all on with turbos and injectors im hopefully heading down to fc tuning to get it mapped. Would I need to upgrade anything else before I map it ?
