ATR43SS turbochargers are engineered to be excellent track /road turbochargers. With strong torque and linear power delivery. There are 5 different types of profiles in total, made for 1.8L to 3L engines. HP rated from 400 to 600HP internally gated.

Pricing include:
Turbocharger Supercore with:
A Nissan Rb25det OEM bolton IWG assembly, NOTE:
Manifold spacer is required for factory Rb25det exhaust manifold fitment. Actuator bracket is made to fits R33 and R34 chassis only. Custom actuator bracket might be required when comes to fitment into S or R32 chassis.
Or
A CNC machined Vband internal gate assembly
High pressure actuator is rated to 18psi, that is included.

Recommendation for Rb25det Engines:
ATR43SS-2 in T3 .73 rear housing. Makes up a responsive 300rwkws on Pump 98 fuel or 340rwkws on E85. Ball bearing upgrade improves throttle response, it is highly recommended.
Oil feeding line is only required for Journal bearing turbo fitment.
Oil feeding line, water banjo adapters and oil drain adapter is required for ball bearing turbo fitment.

Recommendation for Rb20det Engines:
ATR43SS-1 in T3 .63 rear housing with ball bearing upgrade. Make up to responsive 240rwkws on Pump 98 fuel or 280rwkws on E85.
Oil feeding line is only required for Journal bearing turbo fitment.
Oil feeding line, water banjo adapters and oil drain adapter is required for ball bearing turbo fitment.

T51R mod: Unique billet comp housing insert that makes a high pitch jet sound under throttle.

Inline filter is strongly recommended for ball bearing options. Manifold spacer is recommended working with stock Rb25det exhaust manifold.

Bolton Externally gated kits improves power to boost ratio, that is strongly recommended. It might not be legal for road use.

Few notes worth mentioning for RB25det modifiers:

1. Factory intake pipe must be replaced. It is too small for any thing above 240rwkws and sucks it self shut on high boost, We’ve done a back to  back test regarding to it, result is here. 4 inches induction pipe is recommended.

2. R33 GTST with a standard  Rb25det, upgraded valve springs and ARP head studs is recommended for anything over 20psi. Valve float usual result in this sort of curve, that eventually drops and destroys the engine.

3. A good tuner is extremely important for the final outcome. I’ve seen many bad  tuners work, not only making less power with poorer  drivability, potentially cause engine failure. Examples Power curve, Boost curve, AFR. Unfortunately we don’t tune cars, how ever I’m happy to introduce a good tuner to you if you are in Australia.

5. I’ve seen many people use return flow intercoolers for convenience of installations. We’ve tested few and found most of them carry a massive pressure drop in between the cores. Here is a comparison using a Jap branded return flow cooler kit that resulted 8psi pressure drop at 18psi, pressure graph before and after cooler is here.  I personally use and recommend PWR 600x300x81mm front mount intercoolers.

6. Exhaust plays a critical roll in a high performance system. The engine only makes more power if greater volume of air can be shifted through the engine system. Restrictive exhaust can cause an rise in EGT that increase knock levels as well as the inability in boost control. 3.5 inches straight pipe will be ideal for RBs if it not going to be used on road. I always recommend of doing dynos run with exhaust dropped before the finalise of a tune. An example of exhaust restriction: With exhaust, Without Exhaust (dropped from cat).

7. Just I’ve noticed many of the aftermarket turbo back dump / front pipes are not made to spec. Their flanges are much smaller then factory dump print, means the turbocharger will be shooting hot air into a flat wall, that will cause engine detonation and penalize ignition timing heavily. They must be Die-grinded before turbo installation. Photo 1,  Photo 2
