I have the rx6b, and after talking to apexi they have many different trim levels of this kit. I have the 58mm compressor wheel and I was looking at changing to the the same basic turbo with a 61mm compressor wheel and tim levels available from p15-p25. What would u think the differences would be if I changed over as far as response and power?

 

come on someone must know something

 

Well as with all turbos that I know of, increasing the wheel size and trim will obviously increase power, which in turn will lead to slower spool up time. How much I do not know, but I do know that with that turbo, there should be no problem with spool up time. No matter what size of it you have, they are all going to spool fast.
M-P

 

ok, at least thats one response
