Plazmaman Plenum Vs Gtr Plenum

[Adz2332]

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?

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?)

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
