Eric, aka "SUTHNR", has been the proud owner of his Stealth
since early 1996, and is continuously upgrading, modifying, changing,
and customizing the car. It has transformed from being completely stock
when purchased to a highly modified one-of-a-kind showcase that wins
both shows and races.
Eric took home the coveted Best All-Around 3000GT/Stealth trophy
at the 3S National Gathering 2009!

June 2009 Updates
Prior to the National Gathering 2009, the car underwent a bit of
an overhaul, receiving some mods that I have been wanting to do
for a long time. Steve contributed a pair of heads - the old heads
from T4 which have been decked and decked and decked - I'll just
call them 3SX Mega-Deck Ported Heads - and decked again such that
the deck-depth holes are SMOOTH. We figure a little under 2mm of
the heads are gone. Steve also threw in his old Ferrea dual-spring
valve spring kit. These Mega-Deck heads yielded a bit of an unexpected
situation. I already have the 11:1 compression pistons in the engine.
I had been contemplating getting a second NA and building a high-comp
engine, like 12.5 or so. Well, we crunched the math, measured the
engine, and heads (the bowls went from 51cc on the stock heads to
41cc on the Mega-Deck heads) and ended up with a compression ratio
of 13.4:1 - DOH!!!! Got my high-comp engine I guess! That
being said, I had to make a decision with how to proceed - set up
for 100 octane (93 just wouldn't cut it) or make the jump to E85.
Well considering 100 is about $120 for a fillup, I decided to spend
the funds up front and make the jump to E85. Thus the complete underhood
fuel kit went in, Walbro in the tank, and 550cc injectors. This
makes the SUTHNR the FIRST and ONLY non-turbo 3S running E85!

3S National Gathering 2009 - Eric's final 2 AutoCross
runs in 1 video.
Took home first place in FWD class with a 1:09 time.
SUTHNR Drag Racing
The car has proven to be a contender on the FWD purely-naturally-aspirated front with the engine work done to it. The latest trip to the drag strip turned out the following times:
The 3rd thru 6th runs were with a slipping clutch disc :( Third run is the indicator of that - 60' was .15 faster yet ran the same 1/4 mile time and almost the same trap. Eric has a couple other tricks up his sleeve to try, as well as a new clutch disc, to better the times beyond those. But MAN gotta love the trap speeds!
