Recommendation for Rb25det Engines:
ATR43SS-2 in T3 .63 rear housing with ball bearing upgrade. Make up to responsive 300rwkws on Pump 98 fuel or 340rwkws on E85.

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.

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.

Please check out our “Dyno results” tab for power figures and vehicle setups.

This turbocharger must work with an fully operational blow off valve (BOV).

The leading time to build is up to 10 working days.

Developer’s notes:

There are couple of points I’d like to mention for Rb25det skylines modifiers.

1. Factory intake pipe must be replaced. It is  too  small for any thing above 240rwkws, We’ve done a back to  back test  regarding to it, and result is here. Some thing of a hard metal pipe  around 4 inches  is recommended.

2. We did couple of tests using our ATR43G3 .82  rear housing on factory exhaust manifold and found its  restrictive and not  very useful for any thing above 280rwkws internally gated on 98 fuel. To a  proper made steam pipe manifold, there is 2~3 degrees differences in top range  timing with 25kws of power. How ever 280rwkws is still respectable for a  standard engine. Welding an external waste gate on factory exhaust manifold can  also increase power output substantially.

3. If you own a R33 GTST with a standard  Rb25det in  it, then it is a good idea to not run any boost  above 20psi, the factory  valve springs and hydraulic lifters are not strong enough for it. It is noticed  from a strange power curve like in this sheet here, and ultimately wears out valves and valve sets.

4.A good tuner is extremely important for the final outcome. I’ve seen many bad  tunes, not only making less power with poorer  drivability, some of them a  potentially dangerous that leads  to 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 recommend proper front mount intercoolers with core size of 600x300x75mm.

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).
