Howdy everyone. I have been on the road a lot over the past month, so this is just a rambling update.

My hand-sculpted hood scoop got damaged when my car was burgled. I tried to repair it, but the studs pulled out at 120mph, so my intercooler is an intercooker suffering under the stock scoop. Rebuilding that scoop is a huge task I wrapped my turbocharger, but it did not appear to help keep the turbo area cool. Once in a while, my engine stumbles and once in a while my CHECK ENGINE light comes on for a while. I haven't had a chance to call up the codes. Any guesses at what the codes will say and why my engine sometimes "bucks" violently? By the way, I am currently running stock boost levels and stock boost control. After years of having a lot more power than clutch, I now have a kick-ass clutch. Jason Grahn introduced my to rally crew chief Richard Buckner and Richard is a fabulous resource. Richard rebuilt my 5-speed tranny (with 145k miles). The stock tranny is beefy, but the synchros hydrolock and the damn thing just doesn't shift quickly. Richard put in the latest synchros and I can truly say my tranny is much, much better than new. At the same time, Richard installed a high flow fuel pump that I got at JC Sports and mounted (but did not plumb) a 4/1 rising rate fuel pressure regulator. My car is quicker, even at stock boost levels with the high flow pump. If I ever get time, I will track down the ecu error codes, rebuild my big hood scoop, reinstall my APEXi AVC-R boost controller and plumb the fuel regulator. My exhaust pipe always has jet black soot. Does anyone have a turbo car with cray or cocoa brown residue in their exhaust pipe? That's all folks

Hey Bill,

My 90 Legacy has similar thing with the black soot. There's almost always a little around the bottom of the two pipes. I'm not 100% sure why it's there, I have an idea, but no positive things. My thinking is that the black soot means it's running rich or something to that effect. I have replaced my 02 sensor not too long ago, and MAF sensor last summer. I would say those are the two main sensors that control your air/fuel mixture. Other thing I'm toying with is that it's the injectors themselves. I've got 150k on the car. I'm hopefully going to be able to pull the injectors and get them rebuilt not too long from now, goin to send them to www.injectors.com A friend of mine recommended them to me, they test flow before they rebuild, replace all seals, and clean, and test again, as well as some sort of x-ray thing I think. It's still probably a hell of alot cheaper then new injectors. I was told by one mechanic that injectors are only suppose to last around 100k. I don't know how true that is, seeing there isn't alot of people that replace them, but I'm sure with 150k they're not performing tip-top.

About your ECU codes, I've got the instructions to pull codes and codes on my site if you don't have them, www.personal.psu.edu/jcc189/subaru/subaru.html

If you find anything out about the black soot, let me know, I'll do like wise.

Josh

Hi Josh,
I have the same soot in the pipe on my '94 turbo in my Imprezza and
this is a 52k motor. I wonder if the factory may have set the mixture
a bit rich ? I certainly do not get close to the mileage that I had
with the n/a engine. I get about 21-22 mpg around town driving a bit
hard. The injector idea sounds good I have a spare set with my extra
motor it has 280k and I may send those injectors as they are probably
due for some attention and the just swap them.
Alan

I have a 90 legacy N/A. i don't know if it's more so the legacy motors and
or how the ECU's were programed or if they're all like that. Hopefully I'll
be able to have my injectors sent out soon.

If you get you injectors cleaned and swap them, let us know if they make a
difference.

Josh

Running 13PSI, non-intercooled, i never get over %75 duty and haven't
had any detonation problems.

Granted, this is with the stock, clogged, old, rusty, nasty, rattly
exhaust, but yes...these do run rich!

Paul Eklund has a set of Legacy Turbo injectors i'd like to purchase
and get RC'd, because i think i've got one that's intermittently
freaking out.
