There's not many alternatives in the way of ffp's for rb25's. There's the greddys, the knock off greddys and plazmaman and maybe one or two others like a hyper tune one.

The greddy is similarly priced to the plazmaman from memory.

Is that not Plazmaman's fault for not adjusting to the market and shipping it off to China like everyone else has then? :)

End of the day you've gotta play in the market you are in. A lot of top performance places in Aus (and Japan) have been sourcing from O/S for quite a number of years and lower production costs and keep profits and still selling things at affordable prices.

There is the part about Aussie jobs etc, but that is the fault of the Government for poor policy & rising costs here in Aus & competitiveness of China, not the businesses themselves

Could not have been put better.

Yeh there is alot of copies all over eBay for all RB engines and yes I was tempted till for jokes I put in a offer to a company ..... the plenum was 600 and i offered them 300 and tjey said yes and i was like Shit somethin is dodgey here :S

I got recommended these by a mechanic who won't use any other type, if he cant get a plazmaman for the engine he is building he custom makes them , wont use any others cause of bad experiences

Proven at least 15whp gain alone , thats using the stock throttle body, altough if u add a plazmaman throttle body its dyno proven to add another 20whp on top of the gain from the plenum .... I will be doin tests myself so i will let u know how it goes as I have the plenum and throttle body from them goin in this weekend

Yeah, and so do the ebay electric intake fans

So u can return these for full refund if they dont ????? Or let me guess no refunds on them .... these are quality cnc and hand made plenums ur argument with cheap ebay crap is not valid

So, youre saying I could bolt on a Plazmaman plenum to a RB25 and If I dont make an extra 20rwhp with the stock turbo and no tuning I can send it back?

Also...why are there 3 or 4 results straight off the top of my head where cars went backwards after fitting one

both RB20 and RB25

Well I cant find any results for plamaman plenumd sending a car backwaronly good news , there is plenty for the cheap copies everyone is goin on about though , and seriously i doubt a company claims a gurantee claim on intake fans , i bet it days up to 30hp gain , that way idiots believe it and the company isnt liable when they put it in and get no results or imo worse results cause to me it just seems like a block

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
