1.10 around mallala is impossible with what you have got / have planned.
hell mate, with my stripped R32 sedan I doubt Id get under 1min20secs. (cage, coilovers, wilwood brakes, semi-slicks) with a fully rebuilt RB26dett (87mm CP pistons, ati balancer, machined crank/collar, HKS oil pump, N1 water pump, new Cometic streetpro gaskets allround, new belts, Greddy R34 street special cams, hks camsprings, ported head, hks dumps, obx manifolds & front pipe, rebuilt turbos, 550cc injectors, Power-fc..... etc).
a realistic goal would be mid to low 1min 20secs.
