#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 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 |

That is beautiful!! The car is super clean. Past what you listed as next steps, what else do you plan to do?
|
Well I guess my next steps would be,
learn basics of tuning Bigger intercooler, more fuel Destroy engine, learn a streetport then maybe paint and wheels? |
I say forget the SMIC setup and go V-Mount. IIRC ARC SMIC core is pretty small.

BTW, your Kouki Round Tail Lamps are en route to you. |
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 |

Good to know, I'll probably stick to 10 psi with this cooler. Did your rewire maintain the variable speed drive? Or is that moot with the PFC

I believe there is a write up on it by dale clark. |
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"
or, on google: "site:www.rx7club.com cold start" |
I would also check the AWS solenoid and possibly the thermo wax. Those do correlates to cold start idle.
