#slevin build thread
Figured I would make this thread to go ahead and introduce myself, and more importantly to keep all my new questions in one place. My name is Danny and I bought my first FD while stationed in Okinawa in '09, never really worked on it just enjoyed driving it. I've been wanting another one ever since and finally ended up buying this 93VR touring (I believe) last October. Since then I've done the following;
BNR twins
Intake manifold ceramic coated by polydyn in Houston

Intake manifold ceramic coated by polydyn in Houston
New primary injectors
Secondaries sent to RC eng
New OEM engine harness
Silicone vac lines from HPS
Viton check valves
Tested all solenoids (replaced two)
Efini y pipe
Mishimoto radiator
Re amemiya AST
Triumph IAT
FC thermoswitch
HPS silicone all coolant hoses
And lately the tgs cat back
When I bought the car it was bone stock, save for exhaust. Had a bonez downpipe and midpipe, the midpipe was welded to some custom magna flow setup that sounded pretty terrible, other than that it had some boost issues and a sow coolant leak/oil pan leak
My plans for the immediate future is
HKS RS intake, bought on the forums here
ARC SMIC, same
power FC
Supra TT fuel pump
Ballenger A/f controller with ntk production sensor
That's it for now, I'll post some pics shortly

I already have the ARC, it's just gonna be a stop gap till I decide which direction I want to go in as far as intercooler is concerned. Not sure how I feel about vmounts but I understand the limitations of stock mounts where the ducting is concerned. I don't really plan to make a lot of power on this motor. Honestly 300 would be fine with me.
my next concern is how I want to rewire the fuel pump.
Probably getting the Supra TT pump, but not sure how I should wire it

BTW I rewired my fuel pump at the fuse box.

Ok so I've got an issue with cold start. It seems to misfire and run poorly when cold. It runs fine when hot. I've tested and adjusted the TPS and I just tested the map sensor at 0" and idle, both pass the test (when warm) also I've replaced the water temp sensor and my engine harness is new from Mazda. No CEL or codes, just a rough running COLD car. I believe it is more likely fuel related. What inputs does the factory ECU use to control fuel while in warmup?
my plugs are new, new wires, and relatively new leading coil. All the coils pass the resistance test per FSM. Any ideas?
Also, I have the triumph fast acting IAT

Is this a new development? Pretty common with FD to behave like this. Could be leaky/old injectors, ISC, O2 sensor. But, mostly FDs just don't like to start cold. One reason why mazda included the AWS feature. Search and you'll see lots of cold start threads.

My O2 and primary injectors are new. I'll pull the isc off and do the resistance checks and clean it. When searching for cold start I couldn't find much that was relevant. How should I enter that into the search function for best results?

advanced search -> search titles only ->3rd gen specific -> "cold start"
