thats a greddy flop to suit RB25, i hope they have fixed the coolant passage water injection from those copies now :D i have seen at least 5 hydro'd engines from them now.

im based in melbourne and got called out to a workshop (remain unamed) to investigate genuine greddy plenums (turned out to be copies) hydraulic locking engines...... it turned out that a whole batch of these copies landed in melbourne and the manufacturer had tapped thru the water passage into the intake runner.... nice work. just pressure test the water passge if your worried.

Unless its a pretty wild RB20 then dont bother. The std plenum seems to work really well for the sort of power you are going to get out of a 2L 6 cylinder. Spend all you rmoney on good quality bits, mainly turbo and a good tuner and you will get good results

Got this today....Its a KU Engineering one....Friggin top notch welding and design....Im stoaked...Should go nicley.

EDIT: Its really shiny too just my camera sucks the fat wang! (not that shine does anything for its performance) Also its fairly thick - the chamber, not just my old fella :happy: so it shant have problems leaning out a rear cylinder. But time will tell..

couldnt agree more with Roy, i make 366.3hp (on two diferent dynos one in shootout mode) and still have more room to play, only real benifit you'll get is shorter pipe work.. spend the money elsewhere

HEHE Luckliy the figures that I'm chasing are higher. I totally agree that on pretty much any RB20 its not necessary, but it does get rid of alotta pipes and hoo ha when you wanna get to something on the engine :happy:

OH, and if youve spent the money everywhere else and am stubborn like me and wanna stay RB20 then go for eeeeeettttt

What power are you chasing from the RB20? It will be interesting to see what power it makes with the plenum. Be great if someone could do a before and after with the plenum...i would except i just experimented with my engine at some expense only to put it back to the way it was so im shy about trialling anything for the time being

      Unpeeling the Orange

      I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!

      Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.

      The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!

      The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
