Hypergear Turbochargers and High flow Services Development thread

[Genifx]

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?

[Adz2332]

For ATR43SS-2 on Rb25det motor, The recommended rear housing is in T3 .63 size.

 

What power do these roughly make?

[hypergear]

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.
