hi... im in the middle of wiring up my car and i screwed up... its a rb25det neo... i went to start the car... fuel pump charged up, starter motor cranked... and cranking and cranking... but no start... ive checked my spark and my injector wiring and its all correct... i then went to the computer and it smelt like the smell you dont like to smell near electrics... i opened it up and i found a diode or resistor to be had it... ive got another computer on the way but i want to know what caused it to let go... the number of the diode/resistor on the computer chip is D620... could anybody tell me what that diode is... or where can i get an electric diagram of the actual computer... if i worked out what pin fed this diode i could work out where i went wrong by using the ecu pinout... i cannot follow it back on the card because the card is multi layered or something like that....

thanks for your help

Providing your loom came with the eccs and ign relays which is should have, then you should have a spare green relay left over near the kick panel.

Use that, if its still there.

Otherwise go the wreckers and grab another one off a r31.

      Does RB25DE Neo lower intake work with RB25DET Neo Upper intake manifold?

      By GTSBoy · Posted

      I said Garrett style. Not Garrett genuine. And something in the G30 550 range is what you want. Not those pokey little old fashioned T28 sized things. The intake ports in the head are small. There is little benefit in fattening up the runners and leaving ths actual ports small. Just run what you've got. And on the subject of Nistune vs Haltech etc..... You know you can control the transmission with decent standalone ECUs these days, right? No need to keep any of that old Nissan bullshit. Don't get me wrong - I use Nistune on my Neo. But it is a DET, so the number of bodges and workarounds I had to do to make it work in a chassis without ABS, TCS, etc, is quite small compared to the herniated arsehole you will have trying to make it work on a motor that doesn't have some of the things that the turbo ECU wants to see. Just easier to bite the bullet and go aftermarket outright.

      Hmm. Only when the f**king thing is actually working. Still can't find the leak. And that's with dye being put in the last 3 times!

      By R34_GT to Turbo · Posted

      Ok so will run the piping over that radiator and no plenum it is. Put that money towards a Haltech and see what suits. Any ideas something like an elite 2000 or 2500 right? My long term goal is 300kw e85 and manual swap and that’s a dream come true. For now will be 200kw and auto the stock rb25det neo intake isn’t too expensive with throttle body. If I was to have the port matching done, Would that be better than the stock de intake as the det has bigger holes plus has the spots for sensors etc? And suit more long term?  appreciate the advice?

      You understand AFR is not the only thing that contributes to it pinging yeah? Funnily, what the AFR gauge will tell you when it likely is pinging, is going to make you think things are really safe and good.
