The Gt35r is not "too much" for a CIS car. All you have to do is run less boost to make a bit less power and stay within CIS constraints.

Hobieboy, the Gt40r (gt4088r) has almost the same sized compressor wheel as a 35r, and a larger turbine. It will make more power on the same boost, however it ultimately really doesn't seem to outflow the 35r by too much more. The Gt40r is rated at 700fwhp by Garrett. Though they are conservative, I've seen Gt35r's push 650whp and Gt40r's barely push 700whp. Honestly, if you want to go bigger than a Gt35r, you might consider the Gt4094r which is a new hybrid of a Gt42r compressor and 42r turbine. It's rated at 850fwhp so at least it can make a "bit" more power than a 35r.
