which one would be most reliable, quick responsing turbocharger with more than 275 WHP?

 

Honestly, GReddy kit with the interceptor should make about that, and from what I hear should be damn reliable.

 

That's a question that can't be answered as no real kit outside of the Greddy has been publicly available for any extended time.

 

Yea, so technically the greddy by default.

 

As far as turbo reliability, some others like PTP and SFR are using ball bearing turbo's which could likely outlast the thrust bearings in the Mitsubishi turbo Greddy uses, but the Mitsubishi turbo is an older design that's been around forever. So it is very tried and tested.

 

I think he's asking turbocharger , not the kit itself.
275+ whp turbochargers are everywhere,,,,
GT30R - GT35R DBB turbochargers are quick spooling turbo's that can supply enough air to generate 275whp++++++.
There are also series of HKS, precision, turbonetics turbos that are pretty easy to find as well. 275whp+ turbo is not that hard to find, so try a search.

 

Ptp is working on producing a kit with the gt35r using hks v pro fuel management. Might be worth looking into.

 

They are all very reliable (if you are asking about the turbos). The TD06 (18G), GT 35R (PTP) & T4 (SFR/SSR) have all been around forever. All have very good reliability records on other cars. rkostolni is right though that ball bearings tend to last a bit longer.
