So I am carrying a load of about 1200lbs to the scrap metal yard, and noticing how much nicer it would be if my turbo spooled a little sooner. The hills and stop and go were killing me. I daily drive her with a bit on the highway (65-70) and see WOT rarely. The rest of my commute is backroads and hills. Mostly use the throttle for get up n' go. I was planning on putting a Stage III/IV upgrade on the 18.5, but wonder if that plus a 12cm WG would be better? I don't plan on adding injectors or much more fuel (maybe a fuel pin) but I think I am at the limit without an intercooler now. After reading a bit, I am curious if I am pushing too much fuel for a 12cm, or could I make it work. Opinions??

I had a 12cm on my 93 and it was a great addition. The spool up was nice and I didn't loose anything on the top end. I was running about 28 psi with the stock 18.5 cm and ran just a hair over 28 with the 12 cm at WOT. Also I never got into EGT problems. Now if you are running bigger than stock injectors, you may be better served with a 16. But, with pump mods only (and I had done just about all of them) you should be fine as far as fueling goes.

With your fueling mods etc.. I think a 12cm will work very well for you That thing will be way more driveable after the housing mod than it is now. You'll be surprised I'm very sure!

Nice!!! That is what I was hoping to hear!!

I wouldn't be without mine. With the mods I've done to the housing, it will hold the turbo to 32psi even at full load in 5th.
