Help Me Test This Mechanic for His FD3Ablilty
Ok, here's the deal...We recently had a rotary meet here in Tulsa, Ok where I met teh owner of a performance shop. Aparenlty he has 20 years rebuilding and working with rotaries. He can do streetports, bridgeports, whatever. One thing I am not sure if he can do is tune my PFC 
Overall he seems like a really cool guy and I would like to have someone close by (3 miles away) that I can trust with my car.
I am thinking about using him for my rebuild. I am going to visit him and talk a bit about the rebuild and see how confident I am leaving my baby with him to perform such a delicate procedure on her.
I am not doubting he's had 20 years experience with the rotary...but how does 20 years experience with the rotary help you with the FD twin sequential system or tuning in general?
What kinda things should I ask or look for when I head down there?

I think the main thing would be to simply ask him how many FDs he works on a month. A HUGE point for me is if the mechanic actually owns and drives an FD himself. Personally, if I had the choice, I wouldn't pick a mechanic who didn't own an FD.
The other thing you can do is ask around your area and see if anybody else has had their FD worked on by him and what their experiences were.

ask him what Air fuel ratios he thinks is safe to run in boost....the answer is easy 11.2-11.5:1
tuning is not that difficult to get done fairly well.
you need nice easy baby steps as one adjusts fuel...assuming the timing maps are decent....get the fuel right down low...slowly...then move your way up...be sure to get multiple readings for each and every cel that needs to be adjusted. it can be lean at vacuum...and I left mine a bit rich up top just in case...granted I plan on tweaking that some more.
if he knows about timing and fuel ratios he can tune your car...its not rocket science if you have the datalogit and wideband....and an exhaust temp guage.
watch all the temps...intake...water...exhaust....all need to stay within normal operating ranges or your butt be toast.
do not let anyone tune without the datalogit. got me?

Cut the CORRECT*** wires (checked it 80XXX times). Plug up the PFC and Commander and try to start it...no luck, it just cranks and cranks (sounds real healthy though). So I plug up the stock computer and VROOM...starts right up no problems. So I went to Garfinkle aroun 10:30 the other night and we start to try and figure this out. We check the wires that I cut...check them again, and one more time. They are the right ones.
So Garfinkle has a PFC in his car and he also had one in a box never* been used. I tried both of those and still the same....crank crank crank. So we put the new one in his car and it works, it gives him spark and fuel. We are stumped. So we pull a plug out and I crank over. What happens is -> While I crank over it doesn't spark at all, but when I let off the key it gives one spark. If you look through the spark plug hole also there is no mist...which led us to believe the injectors weren't firing either. I've checked the grounds and wires and I've come across nothing.
I've tried leaving a ECU connector off and what happened then is this -> The injector duty cycles went to 2.5 and 3.9% after I let off the cranking. Also when all the connectors are plugged up to the PFC it just reads 0.0% on the Injector Duty Cycle. Garfinkle and I are totally confused. I would appreciate it if someone could give me some help with this, it's alot of money just to have sit there and do nothing
. If you need any more details just let me know. Thanks guys

ahh ok sorry i'm a bit ssssllllloooowww, Check out his shop, you can tell alot by a mechanic by the way he keeps his shop. See what kind of special tools he has to work on rotaries. What kind of oil to run, what kind of fuel to run. See if he has basic knowledge of the sequential system (how charge relief/charge control blah blah blah works). Oh, ask him what kind of seal he uses for the oil pan
That's all I can think of for now

I don't know man. There is a rotary shop around here where the owner drives a turbo FD 20b and has doen a couple of conversions, always has a few Fd's ready for work among other rx7's. He's not that great but can build you a good motor. I do not take my car to him.

Ok, so here's the deal...I just got back and basically he knew what he was talking about...Basically I played the fool (which I am) and asked him **** like the different types of seals and why to choose one over the other. If he's worked on many FDs (mostly 2nd gen but quite a few FDs) what size injectors to upgrade to? should I bridge port or streetport (he recommended against bridgeport) what kinda oil? (redline)...
I proceeded to check out his garage (two cars at a time which means the 3-4 wk turnaround would mean my car would sleep outside while he got parts)
He quoted me $3800 for a streetport with 2mm sealse (not stock seals but some upgraded ones)
His shop is just basic with basic tools, no lift...As far as tuning he had no clue about the power FC but says his partner knows a little bit...I didn't even bother to mention datalogit. Anyway, the search continues.
Thanks anyway guys
