  1. LOL that was me. Yeah its bunky, but noise was just buggered ignition leads causing misfire and no exhaust, that thing's not gunna blow up for a while. Also, 'sif I'm a loser, just cause that i can't afford to make it fully sik and stuff, go before show (i.e. it needs to be able to go before i can show my mates).
  2. The ecu adds fuel as the AFM reads more air, if the ecu just smashed more fuel in all the time, the car would be rich (like this) when not under boost, then stoich when boost hit You can have a turbocharged car with ecu and injectors designed to run boost, remove the turbo and it will run fine. I know this is true, i've done it twice. One time to my ford Telstar TX5 turbo. It uses an air flow meter, just like nissan use. The only difference is the tx5 has one massive injector instead of smaller ones on each cylinder (like a carbie). The turbo blew an oil seal, i pulled turbo out, reconnected the afm and it runs fine, its just really slow and loud. The second time to my z31 300zx. It was a VG30E, naturally aspirated. I had turbo injectors and a turbo ecu lying around, waiting to get a turbo. I had to pull the intake manifold off, so i changed injectors and ecu at the same time. The car runs exactly the same as it did before (misfiring, a little rich, hunts at idle, backfiring on overrun, it's always done this, its an '84 model car). Old injectors were ~180cc, new ones are 269cc (they sound tiny i know, but higher fuel pressure than RB25DE) and the ecu is calibrated to those injectors. We did exactly what i did to the zed, yet i got a completely different result, and my assumption was the fuel pressure regulator, as with the RB swap we kept the n/a fuel pressure reg, but on my VG30E I swapped the regulator with the turbo one (as i got a complete rail). And now that an N/A ecu is running bigger Turbo injectors, when the turbo ecu couldn't run them... it doesn't make sense. If you put big injectors in the car goes really rich, anyone who has tuned a car should know this. You then have to shorten the injector times to get it to run stoich again, which is what the turbo ecu does. Bah!
  3. Yeah, we tried to check the fuses for fuel pump, but i don't read japanese too good. Its still an n/a car, just with turbo injectors and ecu.
  4. Hey guys, don't post on here much (if at all), but i hope u can still help. I searched, i didn't find. Didnt know if this should go in forced induction or n/a forum, since its got aspects of both... There should be an electrical/ecu subforum. Basically, my friend has gone and purchased pretty much everything he needs to turbocharge his n/a S1 R33 (1993) off these forums (bar dump pipe, which he is getting tomorrow). We swapped the injectors and ecu over and now his car wont start. Everything is connected the way it was before and it doesn't sound like the fuel pump is priming, so that would be my first guess. All the turbo parts (bar intercooler piping, which isn't attached) are off the same car, which was running at the time the parts were removed but I'm not sure if the car was an S1 or an S2. So, basically, is there any reason why a S1 RB25DE R33 running just the ecu and injectors from a RB25DET R33 wont start, remembering it may possibly be s2 ecu? Is there any wiring/control differences in the fuel pump/ecu circuits, or could the ecu just be a dud? Only mods to his car are pod filter, exhaust, steering wheel, rims and springs, so none of these should be making the difference. EDIT: He got the turbo bits off "R34GTFOUR" so if you could reply stating if S1 or S2, I was the one who said I would be putting it together
  5. I would be s2k12's friend with the excel. Biggest point proven, its a 1.5l gutless carby 4cyl, and i drive faster in it than i did in my zed (v6). Wasnt driving fast at the time (there were people with me), but i cut a corner and got careless driving, which comes with 6 month licence suspension. I do pizza deliveries as on job and deliveries for Live clothing stores on another job, since its my 1st offence it should be easy(ish) to appeal licence suspension, even if i plea guilty. The cop that pulled me over (well, followed me to my friends house lol) even said its not the car, its the mentality.
  6. Retrofit HID projectors, or i think you can move the globe deeper into the reflector. And what do you mean by its spread out, but like having high beams on? High beams make the beam narrower and longer, not more spread out...
