mr_rbman Posted October 26, 2015 Share Posted October 26, 2015 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.

Hadouken Posted October 26, 2015 Share Posted October 26, 2015 You should have just gone map. Most standard looking. Link to comment https://www.sau.com.au/forums/topic/460587-keeping-under-my-bonnet-looking-standard-r32-gtr/#findComment-7626003 Share on other sites More sharing options...
iruvyouskyrine Posted October 26, 2015 Share Posted October 26, 2015 Or Nismo AFM's. Surely they would be a bolt in affair. 1 Link to comment https://www.sau.com.au/forums/topic/460587-keeping-under-my-bonnet-looking-standard-r32-gtr/#findComment-7626009 Share on other sites More sharing options...
mr_rbman Posted October 26, 2015 Author Share Posted October 26, 2015 hindsight Hadouken.... it did already have the nistune ECU when I bought the car but a MAFless ECU is an option I'm considering......last resort though.

Hadouken Posted October 26, 2015 Share Posted October 26, 2015 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. 2 Link to comment https://www.sau.com.au/forums/topic/460587-keeping-under-my-bonnet-looking-standard-r32-gtr/#findComment-7626019 Share on other sites More sharing options...
mr_rbman Posted October 26, 2015 Author Share Posted October 26, 2015 was thinking about that earlier iruvyourskyrine.......could be an option. Though I would have thought they too would be larger in diameter in order to flow more?!

Hadouken Posted October 26, 2015 Share Posted October 26, 2015 It's all about their resolution at higher voltages or air flow! Diameter wise they can flow a dick load before becoming a restriction.

GTSBoy Posted October 26, 2015 Share Posted October 26, 2015 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 1 Link to comment https://www.sau.com.au/forums/topic/460587-keeping-under-my-bonnet-looking-standard-r32-gtr/#findComment-7626366 Share on other sites More sharing options...
mr_rbman Posted October 26, 2015 Author Share Posted October 26, 2015 Ok, Nismo AFM's are looking the way to go... We sure they're the same bolt up pattern to the standard airbox and which plugs do u use?

mr_rbman Posted October 27, 2015 Author Share Posted October 27, 2015 yep, just used my search skills. $400 each on Nengun :-/ and doesn't look like there's any second hand ones going around.

niZmO_Man Posted October 27, 2015 Share Posted October 27, 2015 A couple have come up for sale. Or you can buy one and I can sell you my other one (my dad lost one, so have one useless-to-me Nismo AFM).

Missileman Posted October 27, 2015 Share Posted October 27, 2015 if you can get the part number you can check the price on amayam, they are sometimes the cheapest option around.

tasty_danish Posted October 29, 2015 Share Posted October 29, 2015 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 Link to comment https://www.sau.com.au/forums/topic/460587-keeping-under-my-bonnet-looking-standard-r32-gtr/#findComment-7628040 Share on other sites More sharing options...
