The vents are good and will look great as well. Yes the rain will get in the engine bay, but no it shouldn't wreck anything, unless you are place a vent right above your pod filter, then yes in the rain, you will suck water into your intake.

Where are the vents to be positioned on the bonnet??? Kind of like a Ford XR8??? Another cheap alternative to bonnet vents is a bonnet lift. The drop in temperature whilst the car is moving is quite substantial!

Easy solution, don't crash then!! I've done the bonnet lift on my car, and it made a HUGE difference to everything, the other thing if you want to start looking at lowering tempratures is to plate off the area between ur bumper and your radiator support panel so the air can only go through your radiator/intercooler...

I have vents on my R33. They look fair shit, but you can see heat pouring out when you pull up to a set of lights. I'm looking at replacing the vents with WRX style vents or buying a carbon-fibre or fibre-glass bonnet in the not too distant future..

na i dont think i would put WRX style vents on a skyline ...do u mean the honeycomb look ones?...im still leaning 2wards those vents i showed ....

Personally I like a squarer vent on the series 2 GTS ( assuming from your avitar ). Better suits the square front and flat bonnet. Something like what they used on the Sierra Cosworth bonnet.

Then again, have you felt the weight of the standard bonnet? That's a good enough reason to invest in a vented aftermarker one.

Hi, guys. I looked into putting vents in the bonnet and I am still very interested, but I was told by a couple of people that adding vents is against the ADR and that the cops are hot on it. Also, it is unlikely that the pits would pass them. I haven't got around to asking the inspectors at one of the WA pits, but I will try to in the next couple of days. Apparently, from a previous thread (can't recall which), they have two concerns: one is when the vent is facing backwards, they reckon you could get an oil leak that would spray oil onto the windscreen, thus hastening your demise through lack of forward vision. Second one is when the vent is facing forwards, all those nice sharp edges are not pedestrian friendly for those occasions when someone drops in unexpectedly for a little ride on your bonnet.

It seems that the powers that be are none too keen on fibreglass or CF bonnets, either. It seems that these will tend to shatter and rip to bits this pedestrian who insists on hitching a lift on the front of your car. I can understand this with fibreglass/GRP, but thought that this would be less the case with the stronger CF.

A bonnet lift will definitely not be passed by our mates at the pits - as far as I am aware.

I am still keen on pursuing vents. I like the R34 V-Spec vent. :aroused: I was also thinking of linking a vent to a cold air intake - the rain over the bonnet will definitely not be as bad as any splashes you get from a low mounted pipe in your front guard vent.

I am also looking at adding GTR vents to my front guard - the ones either side of the number plate. This should work on an R33 GTST SII and may give another option for the cold air intake inlet.

Meanwhile, P1E do you have any pics of your vents?

Cheers.

P1E is that vent for the air filter?

Looks pretty good. I was thinking of putting a NASA vent for the air filter. Something similar to the intake vent on the Evo 6. Was it an easy job to cut the hole on the bonnet? I was told that you might chip and crack away the paint if I was to cut into the bonnet. Another thing is what will happen if water get into the air filter?

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
