See you make a version of the g25-550 and. 660 aswell. Do you have any test of the smaller turbos on the rb25det for us that not hunt big power but whant a good responsive setup for a unopende engine? Looking for a good upgrade for my rb25 powered Datsun 260z. Whant something around the 350-400whp mark. And dont whant a high flow.

Best regards Stian

Hi I found G25 turbine is too small for a Rb25det motor. I recommend our ATR43SS-2 in T3 .71 turbine, its very similar to a G30-660 with better response. Its supplied as a brand new turbo internally wastgated.

How many kws can you see out of it?

Assume the application is for internal gate. 

Far as internal gate concern SS-2 makes around 300rwkws on P98 fuel in either .63 or .71 turbine housing. Response are about the same between the two.

Can you link me to the correct one on your site?

.71 P98 definitely hit 300kws without being to laggy?

Yes correct. Link is at:

SS2 Profile, T3 .71 Turbine housing, Ball bearing upgrade, and oil line kit. Thats pretty much it.

Thank you. Was going for a Pulsar g25or30/660 but then i will look at this. 👍

Quick spool up and respons is the main thing in this can aswell as the sweet sound of the g-series turboes.

Hard time to find ppl using in the size cus every one that post dynos is almost only big power.

Dont know if i can manage to fit a new exhaust manifold this year or if i have to use the stock the first year.

How much more power and lag does the ss3 make?

SS3 has very similar to a SS2. It needs to be externally gated for boost control. Performance wise about 60kws more in comparison.

Thank you, damn want to stay internal. Just have to replace with forged pistons and rods now. So was going for a few more kws

How much difference going internal to externally gated?

ATR43SS-1 is better suited for a RB20det engine. SS-2 is suited for a Rb25det engine. Externally gated kit is highly recommended as it makes more power on less boost pressure with higher power ceiling. I've attached an example of our high flowed OP6 turbocharger running both internal and external gate.  Turbo is boosted to a point that no more power could be made. Car's an R33 with built Rb25det engine.

The SS-2 made 317rwkws V 21U G3 high flowed made 282rwkws at a point that no more power could be made on a built RB25det Neo motor on P98 / Ron 93 fuel. 21U high flow is about 400RPM more responsive making 20psi by 3600RPM, while SS2 made 20psi by 3800RPM.  High flowed Rb25det turbo drives very similar to stock turbo.

My recommendation is still ATR43SS-2 in T3 .71 rear housing with ball bearing core, as it has stronger power delivery with higher power capacity.

We've been working on all sort of different types of turbos with majority of work load shifting towards Euros in the last few years. The Skylines are more of a hobbie then a daily, at least its like that in Australia. I will update photos from some of our latest RB jobs. Whats recent is G30 turbine housing externally gated plumb back kit using T3 .83 geninue housing. It can be made to suit G35, G40 and G42 units. External gate optional.

That's great news

Skyline scene is a bit odd (yes I've been following that particular Facebook page), and most of the owners are young boys with no money.

I thought that the high flowed rb25det turbos were a lot more responsive than the stock one? Would that mean better low end torque?

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
