Little help with small 16g

[AdoreGSX]

I have a couple different things I need opinions on. But first, my mods. I drive a 97 gsx with intake, hard piping, 1g bov, SAFC II, MBC, and a small 16g.

First I would like to know if stock injectors and fuel pump are sufficient on a turbo this small. I have a set of 550s waiting to be put on but i'm having no problem with the 450's at the moment on 14-15 psi, but I am planning on upping the boost to 17-18 psi.

Does anyone have any suggestions for my hi-throttle settings on the SAFC? I do not have a EGT yet...and just want a baseline tune to keep me running decently until I can put exhaust on the car, new injectors/fuel pump, EGT and up the boost.

Also are there any tell tale signs of running too rich or too lean?

If you have the 550cc i'd put them in. I would also go with a walboro 255 pump is only like $100 to be on the safe side and then get a FPR or go with the 190. 17 or 18 may be to much on the stock stuff. A loger or a dyno will tune it tune it the best other wise the cars are to differnt to us someone elses tune. A rich car will sut out the tail pipe and smoke black when on the gas a lean car will have white plugs and run like a rapped ape. Good luck.

Once you turn the boost up, You're going to want to put your injectors and pump in.

Yea, I would drop in the pump and 550s if you go above 15 psi... A blown head gasket is annoying and time consuming (especially of it is your first time).

Do you have a logger? You should be logging at the level you're at now. I ran a Small 16G @ 15 psi with stock fuel system (rewired stock pump) for a year or so. The Small 16g is an underrated overachiever. It is not so small on the compressor map. It is in fact the most efficient of the three 16g variants. I think the small 16g wheel coupled with the TD05H turbine wheel and 7cm^2 housing is an example of a turbo that is perfectly matched internally. Obviously, it is my favorite of the 16g variants .
