Ok, well, here's the situation........

I've got the greddy on, I've got 93 octane gas in the car, and this saturday
I'm buying a J&S. Everything on the greddy is stock, even the boost.
SO........should I retard the timing until saturday, or should I even
experience any knock while driving the thing since it's only on 4.5 psi. (or
what ever the stock setting is, maybe 5) Should I go and get the timing
changed to 6 deg then pay to change it again sunday when the J&S is on, or
will I be fine and greddy is just being very conservative so they don't have
to worry about things like complaints........FWIW, it's pretty cool around
here around now. Anyone that's had a 5 psi turbo with stock timing and a
knock sensor? Did you ever see any knock with that low psi? Thanks to all. :)

IMHO, you should be able to drive it with stock timing (if 10* is what
you're using)...if you don't get on it hard. Greddy uses a fpr correct? You
should be OK, but if you hear any pinging, back off.

If I were you, I'd go out and buy a timing light and learn to do the timing
myself, it's pretty easy, and less time and money than taking it to someone
else every time you want to try something.

Byran,

I've been there with my Greddy. You will probably ping
@ 10 deg at boost when over 3k. Mine did. You might
get away in the winter, but the summer temps only
agravate the problem. 70 deg+ really affect the car as
the heat builds up in the engine compartment. Once
heat soak starts you loose power and encourage
denotation.
If you stay out of boost, shift below 3k and baby it ,
you'll be OK.
As Ross stated, the timing light is a great
investment. You'll be using it later.

Bryan,

You should set the timing to 8*.

Go forth and buy a timing light and a 12mm combination wrench. Then you can
set the timing yourself as often as you like. I'll help as often as I check
my mail, and so will others.

Tip.

Make a mark between the CAS(crank angle sensor) and the valve cover at 10*.
Use this as a benchmark so you have something to return to if you get
confused.

Run some Techron or other high temp detergent through the tank to clean the
carbon from the combustion chambers.

Make sure the plugs are NGK #6 or #7 heat range. Parts Stores and some shops
install #5 and it's too hot for boost.

You're on your way,

Tom

When I installed my Greddy I accidentaly left the timing at 14 degrees. I
DID have ping. I lowered down to 6 and didn't have any. I would suggest
that you learn to do the timing yourself. It take about 5 minutes and is
really kinda essential when working with forced induction. Good luck!

When I was running my stock Greddy with J&S, I actually advanced the timing
to 18 degrees BTDC to take advantage of the low-end torque it offers. Never
had any knock the J&S couldn't take care of. Every engine has different
tolerances for knock, so YMMV. Advance it a bit at a time, listening for
knock (keep the top and windows up when doing this). It might be prudent to
invest in the retard monitor (preferably the dual one, so you can keep an
eye on the air/fuel ratio as well) to make sure the retard isn't off the
scale (>20 degrees).
