Hey all,

I am looking to buy a Plenum for a track GTST R33.

Have read through pages and pages of info.

Im leaning towards a plazmaman or a Greddy as im after useable torque.

But what about a R33 GTR Plenum? What is needed to make it fit? And is it worth doing it over a plazmaman?

Looking at around the 375 to 400kw mark, what size throttle body to go along with the plazmaman would i need?

Any other info would be great

I run 391kw and the 66mm seems to be holding up alright, if its a track car you will be at WOT more than you would on the street so possibly wont hurt to go bigger!

GTR plenum requires more effort to fit compared to the simple bolt on applications as you have multiple TBs etc i assume.

^ GT-R plenum would be worse IMHO because you need to run one of those fugly hacked up spacer plates and that would affect airflow and also the injector spray would be offset.

Of course, it has been tried & tested.. but for 370~400kW why not stick to the stock plenum, but if you have cash to spend might as well get a Plazmaman plenum :)

Thanks guys.

Im after the plenum to clean up the engine bay to.

Also while people are reading, removing the air polution stuff.. is it as simple as disconecting and plugging the holes? wont effect anything?

Cleaning up the engine bay is one thing but remember if you are doing these kind of plenums (well in regards to the Plazmaman) relocate your oil filter and do an oil cooler setup while its apart as its a bitch to get to the filter once its all together! Its even a mission on mine just to check the oil level on the dipstick lol

you mean the charcoal canister? yeah go for gold!

while you're at it, might as well setup an atmo catch can

(it's a dedicated track car that will never see the streets right?)

Yer that little canister with a couple rubber n hard lines running to it. excellent. yer definatly a track only. never ever see the streets!

      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.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
