hey guys ive bought a nissan 200sx with an rb26dett in it the motor is pretty standard only mods are upgraded turbos from an r34 gtr, front mount and exhaust. it is currently running an ems 4424 or 4244 cant remember off hand, any way the car runs but the computer is designed for a four cylinder not a six and the injectors are grouped and coils also. at the moment it has a shit tune in it and fuel econamy is absolutly shit house im talking 250klm being sensable to a full tank.the computer is a map sensor type so i dont have afms and from what i can see they have used the standard r32 harness to the motor all they have done is chopped the blue plug of were the standard compter should go and wired the ems from there.

so i have ordered a standard computer full engine harness and some standard afms and i want to swap it all over

question one is will this work buy just unplugging one harness and plugging the other in and if not what else do i need to wire up???

will all my dash work still or will i need to rewire this also???

just asking as at the moment everything works fine bar my tacho because i have the six instead of the four in it.

any help would be great regards shaun

you'll need to rewire everything between the engine loom and the body loom, such as tacho, temp gauge etc

so all i need to worry about is water temp gauge as tacho dont work till i get a converter, and speedo and fuel gauge shouldnt be affected by the engine harness

      I recently got their dbw 74mm throttle body and pedal kit. It is sensational quality especially the wiring harnesses. Unfortunately I can’t answer u about the fitment to stock inlet manifold as I’m going Rahjab Racing forward plenum. Only one thing to be careful of is understand u have to pay gst and import fees if your purchase is over $1,000 in one shipment.

      yeah i agree paint match stops it from standing out so much, oh that's actually really good to know i was wondering if it would help with air flow now actually having an outlet in the bonnet. Will have to focus on ducting into and out of the radiator now to make the most of it.

      I would paint match the whole thing to avoid unwanted attention  I had a similar bonnet, paint matched, on my old R33 GTST, but mine was a fibreglass jobbie made by Blitz in QLD, they work extremely well for radiator efficiency and under bonnet temps

      Does anyone run this kit with factory plenum? Does the adapter and bosch tb fit under factory strut brace? I wanted to get this setup before going forward facing manifold. Thanks

      small update time, after always wanting a "cool" looking bonnet for my car and always struggling to find one for the series 2 that i liked and wasn't an insane amount of money. Saw one i liked on RHDjapan from D-speed in Japan the price was very good for a carbon bonnet so good infact i was a little unsure how much i trusted it, decided to bite the bullet and with the help of jesse streeter in not long at all it was at my door. Once it was delivered i ran in from work and quickly unboxed it and to my surprise the quality was actually pretty good i quickly removed the old bonnet and placed on the new one to test it out and even the fitment wasnt too bad at all. Then decided to paint the little grille in the bonnet black to stop it sticking out so much.   I decided to not mess around with the hood latch and just install some aero catch hood pins, having never installed them before did some YouTube university classes and i was good to go. fair to say it is not a fun job at all from making brackets so the pins sit nicely and actually cutting through the bonnet but also being very scared of cutting the holes too big it took wayyyy longer than i would like to admit but finally got it there. Then it was time for a quick test drive to ensure the latches actually worked and thankfully the bonnet looked very stable. I still think paint matching the bonnet and leaving just the part that sticks up as carbon would help make it all look alot neater as im not sure how i feel about all that carbon on a very fridge white car but will leave it as is and see how i feel with time.
