My R33 N/A is 18*c when i start up in the morning and when the cars warmed up it stays at around 54*c, i owned this car for 1-2 months im noticing its using heaps of fuel, had a pretty large radiator installed. Its running rich, I get about 300-400km on a full tank,
The car just had its timing belt replaced and waterpump , last owner neglected it for 11 years. Any ideas to get better economy? cheers
