hey guys i need some advice on my setup currently
here are the mods
completey stock rb25 motor
hypergear GT3582 turbo anti surged slotted
50mm external wastegate
740cc injectors
Link G1 ecu
walbro intank pump
stock fuel regulator
splitfire coilpacks
now with the turbo exhaust side i re used my kkr .69 housing which has been modified to suit 50mm gate off it.
I got the car tuned 2 weeks ago and made 400atw on 1.3 bar boost
The dumpipe currently on the car is a 2.75" vband cast iron thing u get from otomoto which then connects to 3" front pipe thru to gutted cat and 3" xforce canon
What i wanna know is basically the car is very laggy, im not seeing 1.3 bar boost until 5000-5500rpm, even between gear changes it will lagg if i dont slam gears to build boost back up.
Could i do something to bring this on harder/sooner? bigger dumpipe? adjustable exh cam gear?
any advice would be great thanks guys.
