DBW on stock crossover plenum rb25 neo

@Murray_Calavera 

It's a V35 Skyline pedal, ie same as the 350Z without the alloy pedal. I did have a 350Z one but wanted one with a rubber pedal.

Where'd you find one of these pedals I can only find the metal foot with a massive top covered bracket area?

Whoops, meant to say G35.

This might be easy for you to access in your part of the globe.

Hahaha Na mate True blue! 

Did you make your own harness for that vq35 pedal to throttle and what ECU did you run it to? I was reading over the haltech DBW diagram last night I have a pnp elite 2500 in the 34. They say to signal ground any linked grounds near the ECU so individuals signal grounds run from each throttle and pedal back to the ECU then you just splice them in before pinning into the plug right?

Yes I did, in hindsight, I should have just bought a fast, modern car like a M2 or 3 instead of modding this shit box.

I ran a new patch harness from pedal to ECU. The power and sensor ground goes from the ECU to the pedal, then it is spliced from there to DBW TB.

If you hop on IG, I have photos of my shit box, @nhbautomotive

That's one tidy boat!

Had a few 33's back in the day yours looks like it rips I think it's definitely far opposite of shit box haha

[Dose Pipe Sutututu]

It's slow for today's standards, does ok around the circuit compared to most boats lol

I would sell this shitbox in a heart beat if someone offered the right money. Will straight away go buy a M3 and let everyone on this forum make fun of it lololol.

What could potentially be done to bring it up to today's standards and do you just not like the chassis or the heart? 

Hey hey hey can't talk about that euro stuff in here!

I was looking over that forum posted earlier from the fella that did the DBW on the factory plenum and noticed how he didn't delete the idle air control and cold start valve?? Also why didnt they mount the DBW throttle straight to the plenum and invert it or can they only be orientated that way. It stopped him using his tower brace 🤔?

Would need a big list like adaptive cruise, lane assist, DCT or ZF, keyless start/lock/entry, adaptive suspension, better sound deadening, more airbags, better ABS system, traction strategy, etc. I'm pretty much describing a M2 or 3 or 4 lol.

Probably due to cost, I believe he just paid a shop. If I were to approach that, I would take off the top plenum and get the flange welded on and then get all the crappy OEM leak valves, emissions crap shaved off.

Ended up completely forgetting to keep tabs on what's been happening so 10 months down the track and with much guidance thanks to Dose Pipe the semi finished dbw build ended with 300rwkw flex tuned on E85. 

Here's some photo spamming.

[SandyBill]

Changed seals and gaskets as I went here and there. Bypassed the heater core for the moment until I pull the motor and aircon to do new heater lines and core fittings.

Replaced spigot bush and added a NPC pull button clutch.

[SandyBill]

Sorry for the wack order of photos...

Got some powder coating done and ceramic coating on the manifold and turbine housing for the Hypergear High flowed stock turbo.

 

After some mucking around and a message to haltech managed to chase down and fix an issue where the dbw wasn't receiving enough voltage. 

[SandyBill]

Replaced all the rear knuckle bushes to gktech units and added some upper camber arms f/r, removed the hicas unit and locked up the rear.

[SandyBill]

Loaded her up and sent it down Newcastle way

[SandyBill]

Hypertune 100mm thick cast end tank cooler welded up and sat right at home. 

DBW flange welded to the Rajab upper half plenum then plumbing through under the battery tray.

45mm external gate fitted up and plumbed back into the down pipe.

[SandyBill]

Hot side plumbing and bov/air oil separator recirculation all done. (Had to make a nice mount for it as the one that came with it was very flimsy stamped crap.

[SandyBill]

The big day

Got her home safely.

Just have a few more things to fiddle around with and change but I'm very very happy with the end result and I'd like to thank 

 

Dose Pipe (NHB automotive) for taking so much of his not existent spare time to talk me through so much shit I honestly owe this man my car. 

 

MK raceworks (Matt) Extremely talented, cool, kind bloke did above and beyond with all the fab work and resolved all and any issues without a break of sweat. 

 

DVS Tuning (Jez) For being patient with me for 7 years endlessly talking about getting the car there eventually and then having the patience to fit me in last minute you sir are a legend.
