I have the rhb5 but my buddy said he woud trade me for a k26 off an audi I have no idea what the stock wastegate is at on this turbo I just looked and it said 14psi on the othere post but just kinda wonderin oh yeah this is for a stock d16z6 please which one would work best

 

there are different k26's but I'm pretty sure most of them are bigger then the rhb5.but there are different rhb5's as well, for exaple the ones off probes and the ones off the ihi tbirds. the k26 I have is roughly about the same size as my 60/48 garrett off a t-bird. if the k26 is in good shape I'd rock that one over the rhb5. if you looking for info on how to lower the stock wastegate on the k26 look here, https://www.homemadeturbo.com/forum/...;threadid=3359 . I guess it depends on what your lookin for the rhb5 will give you quick spool but will probably die out in the upper rpms's. the k26 will come on a little later but pull harder on top. that would be my choice any ways. if you want I can throw ya a couple compressor maps so you can compare them.

a couple of maps, http://www.graphics.cornell.edu/~v/compressormaps/ I'll have to look to see if I can find the others. the rhb5 map is hard to find
