Basically I like the idea of popping my bonnet and it looking virtually standard to the untrained eye.

I had a fairly heavily modded R32 GTS-t with an RB30 twin cam and I was able to achieve this but I'm finding the task a little more difficult with my R32 GTR.

My mods aren't by any stretch crazy..............R34 GTR N1 turbos, Nistune ECU, Z32 AFM's, 650cc injectors, walbro fuel pump etc..............

Now the issue I'm having which I'm a bit annoyed at myself didn't click earlier is trying to bolt up the Z32 AFM's to the standard airbox (sourcing this was a nightmare in itself), naturally they flow more as they are larger in diameter and therefore in turn the bolt holes don't line up, its not as simple as just redrilling the holes as one of the connection points for the AFM to the standard airbox is recessed.

Basically I'm hoping that people have gone down the same path as me (trying to make the engine bay look standard) and have a relatively easy fix for me (adaptor perhaps?!)

Cheers in advance.

Best option.

Sell z32's

Sell ecu

Get map like link or motech and don't worry about blowing a vac hose and be stranded to get raped by predators in the wild suburban streets.

Keep factory air box without hacking it up.

The cleverest solution to this problem is;

  • Use ECU with MAP sensor, not AFM,
  • Take the guts out of buggered RB26 AFMs,
  • Install RB26 AFMs so they look like they're still used,
  • Wire up a circuit from the ECU through the (now unused) loom plugs of the AFMs so that the car will stall when they are unplugged.

This then makes it look perfectly stock, and will also pass the "functionality test" that the more educated among our law enforcement/revenue generating public servants might know to do to check if the AFMs are used by the ECU.

Don't complicate things.Just grab Nismo AFMs since you are running N1s. Easist way to go when everything is weighed up IMO. The re-tune on the Nistune would be a breeze to boot

r35 GTR afms. You can buy housings for about $150AUD on ebay (check ebay UK too), then get a pair of sensors and pigtails. sensors are from any parts shop and the connectors themselves I ordered from Ballenger motorsports. but any place that does wiring bits will do it. I have 200usd in my whole set-up

    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
