I need to know the spec on the greddy turbo TD40H-15G and the spec on TD05H-18G because My turbo is diening off after 6400 rpm, I thought it was fuel but I upgraded to 370 injectors, In line 255 high pressure fuel pump, Field Vtec controller to Richen or lean at any given rpm, I also have FMU,I richen it at the top because it was running lean at first. I called one of those turbo specialists and explained my problem and he I need to tell him the specs on Turbo before, I have the TD40H-15G right now, I was thinking of getting a TD05H-18G from the Si/GSR kit but I didnt know if it would bolt on. I need A/R Ex and In.
Any help please.

Hey vteccivicsi92,

try this link, its got some info on how to read Mitsubishis turbo coding system.

A lot of the stuff may only apply to 3000GT VR4's so be careful what you read. scroll down to where it says"MHI TURBO NOMENCLATURE" thats where they start giving you specific measurements for compressors and turbines.
