Hi, I recently crashed my r34 GT into a kurb then tree sadly. 

Ive done all the mechanical myself ( making it driveable for the panel shop ) and will be getting it back within the next week or 2

The bottom half of the air intake box was completely smahed up ( The MAF unit and everything above is undamaged ) 

I have purchased what I am hoping ( but am unsure )  are the right parts ( K-N universal pod filter + Maf unit adapter )  as to make the pod filter work so my whole intake is back up and running as a whole . As Im a 1st year apprentice mechanic with nissan so the knowledge isnt there just yet so any help is appreciated.

IN terms of performance and heat should  I be worried or should I do anything else in order for everything to be back to how it was?

Do i need to get a heat shield for the pod filter 

Do I need to get it tuned professionally ? 

I have a rb25de 

Thank you ! 

 

 

This isn't the fun answer, but the stock airbox and snorkel will outperform a pod filter that is naked in the engine bay on a naturally aspirated car, if you can source that I would be sourcing that. That performs as a pretty good cold air intake, and I do not think you will be having vaccum under full throttle with a RB25DE to necessitate a larger intake system at all.

Yes I know it got smashed up, but I'd just be on the lookout for a stock NA Airbox/Snorkel combination while the car is being fixed up panel wise. It'll work, and it WILL fit.

ah what a shame then. Guess ill keep my eye out and will just use the pod filter until I find a suitble replcement 

Theres an ex welder at my garage who offered to size up and cut a custom heat resistent sheet metal box sorta thing to keep it hidden. Im thinking if he can do that then I shoullllddd be ok depending on where air is let in through the front. IM not to sure tho

Im also kind of considering running some pipping with pod filter  from the intake manifold down to the bottom left of the bumper wheres theres an open bumper vent for clean fresh air  however I havent had the car back in almost 2 weeks now and havent had a chance since thinking of this to go in and see if there would be room to fit a 3 inch pipe down through/around the ac and radiator area sorta thing 

What would you say about that ? 

 

Thanks for your help man

I have done this, and made a custom airbox with two pipes that run down through the (turbo) stock intercooler holes that are in that section, to duct air from the opening in the front bumper. It works really, really, really well.

The reason it works well is I noticed how hot my intake air temperatures actually were with a naked pod filter in the engine bay, but because my car has a V8 in the front of it, I could not use the stock snorkel system so I had to make up a box and duct it etc, the details are in the most recent posts (ish) in my build thread in my profile/signature.

That said, I have a LS in the engine bay as mentioned. You don't. I actually needed the system to draw more air and that air to be 10C on a 10C day, and not 40C on a 10C day, and I can get benefits from a 4in pipe and big intake manifold.

The RB25... just doesn't. The reason it doesn't is because the intake system/airbox is sufficient for any amount of air that the RB25 is going to draw into itself. I would be surprised if the RB25 isn't at 100KPA at full throttle at 7000RPM on the stock system.

if your a 1st year at nissan why wouldn't you ask the techs, most have probably owned a nissan import. yes you need a pod adaptor, you need a 3" pod filter, you need a bracket most fit around the pod hose clamp, probably would not hurt to shield the pod as the cops might defect you.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
