My Z32 TwinTurbo 2+2

Here's a comparison chart of turbo compressor wheel and turbine wheel. Not necessarily sorted by size and power.

I did not list the horsepower rating of the turbos. It depends many variables. I only listed the compress flow in CFM. Some cfm listed are max flow. Others are listed at 2 pressure ratio (PR) or at 14.7psi at sea level. As new turbo kits coming out, if you have the specs (major and minor of compressor and turbine wheels) and compressor maps and want to post them here, send me an email.

Note: some turbos come as a bolt-on kit. Some do not, marked by '*'. Specs are not limited to the chart listed below for those none-bolt-on turbos.

Disclaimer: Greddy modifies Mitsubishi turbos. Due to lack of factory data, all Greddy turbo specs here are referenced using Mitsubishi specs. It may not be accurate.

a Apperantly some TD05-18G kit has just the bigger 18G wheel inside a TD05 compressor housing while other TD05-18G has bigger 18G wheel and TD06 compressor housing. 

b Pentroof of Japan offers kit for TD06 and 2835 for Z32s. Custom made to your specifics. 

c Escort of Japan offers streetable kit of HKS GT3037.

d HKS offers the 'R' version of 2835. 2835R has bigger 100mm compressor inlet. Also, there's a 'S' version of 3037. 3037S also has bigger 100mm compressor inlet. The Pentroof 2835 kit is the regular version with 70mm inlet. The pro version uses internal wastegates.
