2nd Time Round

List as Follows:

KKR-480 (Otomoto)

Custom Tuned Length S/S Turbo Manifold

New 3" Exhaust, 3" Cat, No Mufflers

Custom Intake/Fmic Piping, Fmic Tube/Fin

600cc Injectors

Cleaned/Smoothed Plenum/Runners/Throttle Body

Apexi Power Intake

Z32 AFM

Adjustable Exhaust Cam Gear

Apexi Power Fc

Ebc Dual Boost/Scrammble Switch Soon to be upgraded to greddy profec b

Just Jap Tube and Fin Pressure drop from Just Jap Kit (Soon to be upgraded to Otomoto 5" Core)

Cars Tuned got 258rwkws Unique Autosports Tune but that was on 91ron Standard unleaded Petrol Little to no Timing at all

Had to earth out walbro fuel pump (max voltage) plus problems with walbro not keeping pressure up, evident on dyno. Must admitt is a clean smooth powerline. Runs 20psi but drops to 16psi due to walbro.

Lol Didnt get what i WAS expecting from the KKR-480 , KKR 480 is really responsive on the rb25 comes on boost at 3000rpm full boost at 4400 rpm did change fuel pump now holds 20psi all the way to redline which is great, got 275/18 and even at 100klms or so 3rd spins lol satified me for 1 day.

3rd Time

So now i have the kkr-560 but its been modified/machined housings so should see close to if not over 300rwkws easily, couple of weeks and we will find out. But ill spend the money this time on 98octane fuel lol

Boost comes on later around 3300rrpm and now i have serious problems with fuel on lappy drops to 10psi almost soon as it hits fullboost (Thats with a brand new walbro 500hp pump), will get bigger/better pump (bosch 044) also some Tomei poncams amd maybe nos to get this big suckers of a turbo spoolin up 1000rpms more or so.

Will see closer to 330rws+ without nos thanks to Pulse Racing at Menai!
