sticky280zx Posted March 6, 2012 Share Posted March 6, 2012 Looks like its coming along quickly, but why not just go with a front mount setup since youre going through all that work already? It really isnt that much for a decent setup and would help you up the boost alot not to mention just run better. Quote Link to comment Share on other sites More sharing options...

It really isnt that much for a decent setup and would help you up the boost alot not to mention just run better. I already have a intercooler but no piping, money is short right now. However in a couple of months I will upgrade to the intercooler and up the boost to 10 or 12 psi. Only modification ill have to do is put a IAT bung and a BOV on. No worries, it will happen.

78zstyle Posted March 10, 2012 Author Share Posted March 10, 2012 Night one down. Radiator out, fan out, all electronics disconnected from engine.. fluids drained. All we gotta do is disconnect tranny mount, drive train and pull er out. Quote Link to comment Share on other sites More sharing options...

78zstyle Posted March 11, 2012 Author Share Posted March 11, 2012 and its in. Just bolted in.. nothing really connected. Tomorrow we will be hooking up the megasquirt to it.

78zstyle Posted March 14, 2012 Author Share Posted March 14, 2012 Figured out problem..a transistor was broken on megasquirt so it couldnt handle two banks. Got it to run on one bank and it sounded soooooo good. Quote Link to comment Share on other sites More sharing options...
78zstyle Posted March 15, 2012 Author Share Posted March 15, 2012 Transistor will be here friday but heres a video of it running on one bank of injectors.. rattling sound is the exhaust: http://youtu.be/3zk9C5q38qs Quote Link to comment Share on other sites More sharing options...

78zstyle Posted March 15, 2012 Author Share Posted March 15, 2012 My ugly ass car will be in attendance. Im going to fix some dents and patch a hole and paint it black with a rattle can soon. Quote Link to comment Share on other sites More sharing options...
emeraldlion Posted March 16, 2012 Share Posted March 16, 2012 Lol I know I keep saying this but mine will eventually gets their, bumper shock holes, and rattle can black patches in-tow. Just as a warning, if you want to get a decent spot and not park in spectator parking you are probably going to have to show around 630. People have been arriving earlier and earlier. When I got their at 8 this month it was PACKED. May have to just start a "datsun" row in spectator parking. Quote Link to comment Share on other sites More sharing options...
MadMaxDallas Posted March 17, 2012 Share Posted March 17, 2012 (edited) Just got my 3 inch exhaust done by Lewisville mufflers (lorenzes) muffler shop in Lewisville Texas. 337 out the door with a magnaflow muffler...cool guys and did a great job..I would recommend them. - 78zstyle Edited March 18, 2012 by MadMaxDallas Quote Link to comment Share on other sites More sharing options...
78zstyle Posted March 18, 2012 Author Share Posted March 18, 2012 Yeah so megasquirt decided to stop working. Megasquirt has been a nightmare from day one. Quote Link to comment Share on other sites More sharing options...
78zstyle Posted March 20, 2012 Author Share Posted March 20, 2012 Turned out the megasquirt processor "died". It won't even accept any sort of boot code. Hooked up to a scope and saw that the signal was making it to the processor, but nothing came back to the computer. Also blew the opti coupler.. I don't understand how it happened, there are fuses.. and diodes to act as failsafes in that case.. but they didn't do their job apparently. I am receiving a new unit tomorrow morning, overnighted from new york from another member. I swear to god, if I can't load my tune, plug that ***** in and drive off the exhaust parking lot with my brand new 3 inch exhaust, I will torch the car.

78zstyle Posted March 21, 2012 Author Share Posted March 21, 2012 Well we had fun tonight. Finally figured out problem, I was using original +12 source wiring to feed injectors. Did quick rewire of source to 12volts going to megasquirt, made a few changes to the map and took it for a spin. Will do more fine tuning and checking things over this week, but not bad, big smiles. Enjoy the short video. IMG_0833.MOV Quote Link to comment Share on other sites More sharing options...
78zstyle Posted March 21, 2012 Author Share Posted March 21, 2012 wastegate for sure isn't working correctly, hit 13-14 psi without even trying. Quote Link to comment Share on other sites More sharing options...
78zstyle Posted March 22, 2012 Author Share Posted March 22, 2012 Changed spark plug gap from .030 to .025. Fixed fuel rail vacuum leak, changed timing from 20 degrees to 25 degrees. Car runs SO much smoother, i was getting into boost tonight after the changes pretty good and got zero backfires, stumbles or misfires. Only problem: I'm overboosting like hell (Note this was unintentional overboosting, im not stupid) http://www.youtube.com/watch?v=enAHUdk9KDk&list=UUxfaXVq0Q6N1ufKDkOVWiSA&index=1&feature=plcp Quote Link to comment Share on other sites More sharing options...
MadMaxDallas Posted March 22, 2012 Share Posted March 22, 2012 Ummmm let's get that fixed lead foot. And a few hundred more miles out of this head gasket lol Quote Link to comment Share on other sites More sharing options...
78zstyle Posted March 22, 2012 Author Share Posted March 22, 2012 Ummmm let's get that fixed lead foot. And a few hundred more miles out of this head gasket lol That was only ~60% throttle. But yes, I need to be careful. We might need to change the wastegate actuator spring? I don't know. Quote Link to comment Share on other sites More sharing options...
