Hey guys had a question on the 1st gen fp green so thought of posting it here than making a new thread, I recently purchased a 2nd hand 1st gen fp green turbo (JB), the turbine had a very slight shaft play, should this be a major problem? I am new to this and kinda worried.
As long as its slight side to side and not in and out you should be fine.

I've been looking at upgrading my 1g FP Green. From what i've heard, the general consensus is the old school green is a little better than an Evo IX turbo but not by much (that would justify swapping out a IX turbo for one.) On pump gas (92 here) they tend to top out at around 400 give or take 20hp. Of course you can get higher on E85.
As for the other question.

From Forced Performance's FAQ:
Q. The shaft in my turbo feels loose. How much freeplay should I have?
A. While this specification does vary from one brand to another and rule of thumb is less than .030" radial freeplay and less that .002" axial freeplay.
This amount of freeplay is required to allow the bearings to "float" in a pressurized film of oil while the engine is running. The flow of oil through the clearance around the bearings is what helps the bearings stay cool. This oil film around the bearings also help dampen vibrations that occur to the rotating assembly as it moves through it range of RPM. Ball bearing turbochargers do not have this pressurized film of oil around the bearings; this is why they are somewhat more noisy than floating journal bearing turbos.
