Gator's 1982 Kp Starlet 4age - Discussion

Looking good man. If the car doesn't start until you let go of the key, then it wouldn't surprise me if they got the feed for the coils from the normal 12v feed, but that turns off during cranking, so you'll have to find a better feed for that... You would normally run a couple new relays driven by the ECU that get fed by the fuel pump signal (on when the car is running and starting) and use that to power the fuel pump and the ignition (and injectors if you had them) and then another relay to drive the fan from the ECU as well.

Didn't you say the ECU doesn't have a temperature input hooked up? You should hook it up. The temperature is one of the more important inputs to the ECU. I'm not actually 100% sure if it adjusts timing with temperature so maybe its not actually important unless its supplying fuel as well... Maybe ask a 4A guru

As mentioned in the build thread.

 

car has failed a wof and they have listed 

 

Improve front brake effort.

 

should I just to pads and skim ect or should I go the whole hog and rebuilt the booster?

you mentioned your tuner suggested DHLA40's were too big, I suggest your tuner didn't quite mean that or he doesn't know whadeestalkinabeet.

 

Most 1600s that run a twin sidedraught setup will run twin 40s to provide room for engine modifications. The size of the carb (40-45) means nothing other than what main venture (choke) size it can run. a DHLA40 can take a maximum of a 36mm choke, whereas a DHLA45 can take up to a 40mm choke.

 

A 1600 engine that makes peak power a 7500 rpm should run around a 34-40mm choke. A typical BDA choke for a 1600 would be 38mm for track and 36mm for rally. Maybe yours is choked a bit too big so is losing port velocity down low. Id suggest taking it to a decent carb tuner with a dyno and getting them set up right, it could make a world of difference.

mine are 45mm . he suggested 40mm and he knows what he is doing he normally messes with escorts and such but lets be real a 4age is just a bda ford motor refined

but your information is exactly what I have found time and time again thank you.

 

and as for a proper tuner Im waiting till i have the cash to swap to 40mm one then a tuner with a dyno will be the best way

Sorry I just don't understand why you want to swap for a

40mm carb, it will do nothing, absolutely zero, except limit you if you ever want to do engine mods. It is the choke size that matters not the carb size, you can run a 1300cc pushrod K series on 45s just fine, it just requires 30-32mm chokes. Swapping a good set of 45s for an unknown (unless the are brand new) set of 40s is just going to potentially give you a sore wallet. Just get the 45s jetted and choked accordingly, they will be mint.

The 40 / 45mm is just the body size of the carb and defines what size chokes you can run, it is the chokes that determine flow / airspeed, theoretically you could run a 600cc engine on twin 45s if you had chokes small enough
