well its the last upgrade i can c my self gettin power out of, cams are done its been bored out computer turbo blaH blah blah i think the plenum is the best way to go if i can gain 30more kw @ the wheels that will definatly get me over the 300rwkw mark

I would mate. If ya have done everything else that there is to do, then fire away. Dont worry about everyone else who says not to, try it yourself. LOL - then we'll all be asking u the questions about it all!

I keep coming back to this mod as well. Its pretty big money, but woudl be money well spent if it fattens up the mid range. Though by the times its installed and car tuned its a $2500 exercise so would need to be pretty sure it works....anyone willing to take the plunge on an RB20?

LOL, people referring to results on RB25s doesnt do anything for my confidence

[Psymon]

I'm keen to do one... and if money and time permits i'll try and do a before and after dyno run. At least you'd think there'd be some gains in response due to removing a metre or so of intake piping?

[bubba]

I don't see how a forward facing plenum can starve cylinders 5 & 6 of air. It might starve cyl.1 and maybe cyl.2 but cyl. 5 & 6 would get more air if anything, causing them to run slightly leaner and I believe that is the issue some people have with forward facing plenums, leaner rear cylinders.

roy my car is goin in on the 29th to get a new turbo and mani so i think ill b going 4 the plenum aswell ill post a dyno when its all done 4 ya m8.. ive spoken to a few ppl here in perth and they rkn that the plenum is a win

so your agreeing with him.. than why the f**k do we bother modifying cars.. saying something like that is absolutely stupid. if everyone took that attitude we'd all be driving dead stock slow shitbox's. when someones chasing hp offer them advice. instead of telling them mods are useless cause you'll be use to them with in a week of them being installed..

Hi mate,

did u have an after market ecu or just the remapped stock ecu?

anyone know if we need any computer upgrade to work with this front facing plenum?

cheers

no u dont need a aftermarket ecu or remap to run the plenum. i installed my one and working fine for a month b4 i went and got a remap+tune. just the idle was abit off thats all. also keep in mine that the piping goes where the battery is so u will have to put the battery in the boot. about 6hrs of work if u dont have ur misses in ur ear all day

I would like to know what do you think of Plazmaman Plenum?

i was looking at the greddy plenums but as mentioned the 5th and 6th cylinder dont get enough air so i opted to pay the extra 200 bucks for the plazmaman plenum, she works well and i think it helped reduce lag from my to4e but that might just be me.

[PM-R33]

I got one on the 25, even if it doesnt give you any performance gains, the fact it makes your engine bay go from looking like ass to looking sexy as hell is worth the money. I cannot stand the standard RB20 and RB25 plenums, look like absolute sh*t!. Also makes working on your car so much easier because you dont have a million things in the way. If you can afford one and want one, get one.

[ZILR-34]

hey guys Finally i got around of takin sum pics of my plazmaman setup.

cheers

well i have one on my R32 and i think its a good upgrade. i gained 30kw after i have my tune to get it running right. i say if u got the money go for it. but other people will say spend ur money on other things. have a look at my dyno sheet attached

cheers

Well history repeats. I am back here again and again thinking about throwing one of these onto my car. So as a before and after mod you are comfortable that there was a gain from the manifold, and not from the tuning after the manifold went on...ie Dr Drift had tuned the thing optimally before the manifold went on??? Going from the TD06-20G to a TD06-25 i am going ot need to do some work to get the old girl responsive.

So torn between a Plazmaman setup or an EFI Hardware multi throttle setup

[R31Nismoid]

If you can get multi TB's Bris - that's the way to go if your after response

[Italiazr1]

what power you making now? as too before?

ive got one on mine but never checked for gains before and after

i just went the whole hog when i blew the sh?t out of my engine 2 years back

never really noticed results as the car was off the road for 18 months

[raZ1911]

I thourght having the runners shorter it would give less torque?
