@admiral323 just an update on this issue incase it helps anybody else.i spliced the red wire from the ignitech into the brown coming from the ignition and have never had a problem again
@admiral323 Yes but you will need some other parts from the WRX as well. Ie. Front forks which will most likely need a custom spacer made up, full front brake, wheel spacers front & rear and the speedo drive. The DTX is an easier swap see here dude;
@admiral323 yeah sounds a similar climate, ofcourse jetting is dependent on many factors, but generally I've found the standard DT jetting, especially on late models were way lean.
have bought a second hand normal dt inlet that im going to trim out.i have the original 4dl 32mm joiner and will try to join that to the original.i have ho idea of the needle size thats currently in it but she is fairly thin and pointy.ive went the opposite way to you and bought a u1 needle to try.the jet size is a 148.
If it is a 1998, then it should be an older loom type and CDI, with a much higher Ignition retard around 10,500 Rpm.
But it could have the final CDI type 99' onwards which is restricted to 8,500 Rpm. So there is no way getting round that without a custom CDI or retro fitting a Pre 1994' loom.
But you need so many parts to convert to an older CDI, it is pointless!
Look up Zeeltronic or Ignitech CDI systems, if you want true engine performance.
