Hi guys, so i drive an R33 gtst 1995 Series 1.5.
my engine mods are as follows:
Apexi Power Intake
Apexi PowerFC
Apexi PowerFC Boost control kit
Z32 AFM
Cooling Pro Intercooler Kit
Cooling Pro Oil Cooler Kit
HKS GT-RS Turbo Kit
HKS Exhaust Cam Gear (set to 4deg retard)
HKS Timing Belt
Splitfire Coilpacks
HPI Exhaust Manifold
Xforce 3.5" turboback exh, with bell mouth dump
Datalogit
PLX wideband AFR Kit
ok so here is the go:
i do all my own tuning, i tune to the following:
14.7-15 afr on light load (basically rows P8 and less)
then as boost comes on we go to 13.5 and head down to 12 afr when we hit full boost at 1bar...
city driving i get 300kms to around 50 litres, thats 16l per 100kms...shithouse if you ask me.
i wanna see 400kms to a city tank!
110km/h i see around 500kms to 55litres roughly and around 400kms if its 80-110km/h long distance work...
i have cleaned everything, AFM, plenum, aac valve and associated parts....checked base timing (19deg indicated - 4deg retard on the cam gear = 15deg base timing) etc
where do i look now??? engine rebuild...lol
