Intake Plenum Question

Hi Everyone,

Does anyone have any info/suggestions with regards to the standard intake plenum I have on my R33 GTS-T with the piping running over the motor to the throttle body.

Which of the following options would be best?

1) Aftermarket plenum (e.g. Greddy). I know that I can get one delivered for just over $1000

2) GTR plenum...is this possible? if so what other parts would need changing to make it fit? What would the cost be?

3) Have the throttle body location moved on the standard plenum? Is this possible? What would the cost be?

...or is the standard plenum fine as is running the piping over the engine from the front mount and spend the money on something else? I am looking at getting power up to 300rwkw, and thought that the heat caused by running the piping over the motor would not be as good as having the piping running straight up to the throttle body like the GTR.

Any info/help would be greatly appreciated. Thanks

Did you try searching the forum?

I think sydneykid mentioned the stock plenum was good to a specific power figure but I can't recall the figure.

Ed, after a bit of searching with different search criteria, I came across the thread you were mentioning. Sydney kid mentions the standard plenum can cope with up to 450hp without restriction...not sure if this is crank or atw.

So I can definitely forget the aftermarket plenum and stick with standard. :D spend the money on other things for the car instead.

What about the piping? Will the piping to the standard throttle body position get in the way of a high mount GT35R?

The 180 degree bend at the throttle body style of pipework is the go.

I have a picture of a car fitted with the 180 degree pipework and a high mount, but this new forum is taking some time to get used to.

:D cheers :P

Hey SK, thanks for the pic...looks like it should shorten the pipe a fair bit and looks good to. Was that custom piping made by anyone in particular?

Thanks,

side note, you dont need a GT35 to make 300.. its overkill.  :)

I was also looking at a GT30R with a .82 A/R...may still go for this instead of the 35R. ;) cant wait to start working on it all but will have to wait another year. Then I will give it some attention. :)

Just letting you know thats a Hypertune/Performance manufacturing piping kit.

They have moved from inside the same building as where plazmaman is, but they are now down at Tarin Point.

They will also be doing a plenum for the RB25 very shortly wich replaces the inlet runners.

These are the guys that did all our piping on our GTR.

Give then a call

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.
