RICE RACING will become famous soon enough
Walbros eat more cock than the members in the BAW thread

I personally use a single SARD 280Lt/Hour unit
I run it at 45psi base pressure (no motor running) SARD Type RJ reg
I use a Keene Bell Boost A Pump at 100%
I use ID1000 primaries and ID2000 secondaries
I run everyday 30psi boost
I now run it at 35psi boost pressure
I run RRWEP140 WM50 water injection system
I run Full CDI coil on plug system


The car is a mother fucking rocket ship!!!!
With 275 Toyo R888 on the back (GG compound) it will destroy the tires in 3rd gear (goes to 100mph in this gear) and does 100-200kmh in high 5 second range.

FYI: Good sports tires wear rating of 180 (v's 100 for race tires) and you are like driving on ICE in the dry with hot rubber....... its fucking insane.

Other tip bits

Garrett T04Z turbo 1.32 A/R
Tial 46mm WG plumbed back
3.5" full exhaust with two SMB mufflers
Exeddy twin plate carbon clutch (D-Core)
Link G4 plug in board (stock ECU case)
Sensystems 3.5bar+ map sensor (works to tested 40psi)
RRWEP140 also works as an Intercooler spray (needed when you go over 20psi boost)
HKS exhaust manifold (modified by me)
Full EGT feedback to ECU
Fuel pressure feedback
Exhaust pressure inlet and outlet (not used as feedback item) but is all logged
BLITZ I-Color Spec R (best boost control & mini logging system, very very handy)
Race Logic traction control, only one that works on a rotary engine in fuel cut "correct" mode
11 heat range spark plugs (daily driven, idle as long as you like, never ever fouled! thanks to CDI & COP system


My engine is a 3+ year old 100% stock standard 13B-REW motor, new out of the box, but never refreshed or modified in any way shape or form.

Car makes over 650bhp, its reliable and fast, no dyno sheet races here, whoever you buy parts off get them to show you some proper logs of a Race Logic system and see how long it takes to accelerate from one speed to another, this is the key to separating fact from fiction

Good luck in your build up
