RUZN Posted April 12, 2009 Share Posted April 12, 2009 Listed of changed items: 3" exhaust pipe to 3"in out Magnaflow Exhaust K&N filter cone 1985 Maxima VG30 MAF (6pin) 300zxtt TPS 1992 60MM Throttle Body (custom cable throttle) Ported intake on Manifold and Head as well as 60mm port for TB adaption 1987 300zxt Turbo 1987 300zxt ECU Stock 280zxt O2Sensor (which I hear needs to be replaced for this conversion) Stock Jpipe for now waiting on intercooler Stock Turbo 280zxt injectors stock fuel pump ok so I set TPS to be 0ohms at closed TB and at about half it dose its infinity thing so if I am correct that means it is working. So if I just use about say 20% throttle its great its got a sweatspot at about 65% to 75% throttle but if I JAM ON IT! I get not much accel it feels the same as 75% throttle if not more laggy. Sounds like tons of air is going in but no GOGO.. Now at 75% throttle I can hit 140kmh and still climbing and at 100% it still accelerates but its not liek it was before using stock ecu. so What could be the issue? the 1985 Maxima MAF? is it set for lower air ratio? is it the 280zxt O2 sensor with 1 wire and it needs the 3 wire 300zxt O2 to read higher TPS and intake readings? I cant figure it out. turbo is nice and loud sucking tons of exhaust and pushig tons of air so the turbo isnt screwed from the sounds of it.. there was only minimal shaft play like MINIMAL. soooo not sure whats up. Pics on my album.. maybe you guys can help me out ty I have gotten no replaies in the S130 section for days Quote Link to comment Share on other sites More sharing options...

RUZN Posted April 14, 2009 Author Share Posted April 14, 2009 Yeah followed instructions. I recently got a O2 sensor with 3 Pins and it was compatible with the stock Flange on the 280zxt downpipe SCORE!! hehe I also changed the TPS originally i had one from a 300zxtt which has two pigtails and cant be matched so I got one out of a 300zx N/A =-) Working great now! Just waiting on my FPR and intercooler now! ty though for reply Quote Link to comment Share on other sites More sharing options...
