no unless you sold the t3 housings that they came with and bought the t25 housings.
I am not talking about the housing i am talking about the flange that you bolt to the exhaust manifold. how much bigger are the 2871r comparing to the 2835, will they spool later and if so how much later.
thank,s

viking, the flange that bolts to the manifold is part of the housing:confused: HKS 2835's use a t25 housing which has a T25 flange.

2871s are good for around high 300whp to low 400whp depending on a/r. They are almost like the 2835Rs except that have the T3 housing(T3 flange). So you will need a t25 to t3 adaptor or you would need to get T25 housings for the 2871s

Hope this helps.

Sorry antonioz32, trying to help out.

no prob, but those turbos will do 400+ each no prob. I know of built 1.6L d series honda motors that are built making low 400's, and everyone knows the d series is a horrible flowing head.

Thank's for the info, i just looked on the garrett website and it says that they have t-25 flanges but it looks like they have internal wastegates.my 2835s have dubbel external wastegates. so the 2871s might not work with my setup.

What would be the spool differences between the 2835 and 2871r?

Viking.
