Dose Pipe Sutututu Posted January 31, 2007 Share Posted January 31, 2007 the plenum needs to get a nipple welded to it... so you can connect that PCV to it. Link to comment https://www.sau.com.au/forums/topic/154299-custom-plenum/#findComment-2869474 Share on other sites More sharing options...

tmc_2 Posted February 1, 2007 Share Posted February 1, 2007 Just block it off mate, that will be fine, cops are only concerend cause its venting to atmo. U can safley block that sid eoff as ur other hoses let the crank case pressure escape. Personally its a good excuse for catch can. Quick fix block it off Link to comment https://www.sau.com.au/forums/topic/154299-custom-plenum/#findComment-2871927 Share on other sites More sharing options...
cruzin33 Posted February 1, 2007 Author Share Posted February 1, 2007 I got the plenum with the car so i have no idea where to get one or how much its worth.I like the catch can idea where could i place it in my bay and is it a defect, If it is i recon welding a nipple on would be the next thing i would do but will this change the engine performance in any way?

Craved Posted February 1, 2007 Share Posted February 1, 2007 you dont really need the PCV get it blocked up, then run your other lines to the Catch can, but have the catch can return to the inlet piping. its legal then and will still function Link to comment https://www.sau.com.au/forums/topic/154299-custom-plenum/#findComment-2872126 Share on other sites More sharing options...

GTR-90D Posted February 5, 2007 Share Posted February 5, 2007 whats better a mass produced Jap cast plenum or a custom made one from local hi-po tuning shop? Link to comment https://www.sau.com.au/forums/topic/154299-custom-plenum/#findComment-2882744 Share on other sites More sharing options...
2gceffy Posted February 5, 2007 Share Posted February 5, 2007 (edited) i bought one of those relocated throttle body plentums and my mechanic refused to put it on unless i had a safc or something, he grabbed a genuine greddy one and showed me/explained how these stock ones front goes low then high then low presure so you will have different volumes of air in the plentum.. when the greddy ones start high and wide then thin/lower towards the back to keep the presure the same across all cylinders.. he rebuilds engines allday and has every kind of machanical degree so i sold it ahah anything he doesnt like i wont buy but ohwell i respect his knowledge n experiance.. i really liked it though ahaaha before and after dyno runs would be very interesting just looked at your photo and you can see how they incorperated what i was talking about into that one, looks rediculously clean and very well made !!!

So ur mechanic recoommended a Greddy intake over the cut and shut stock item? I see what he is saying about airflow, makes perfect sence. I think i will take his advice too.

DJRIFT Posted February 6, 2007 Share Posted February 6, 2007 i personly think the forward facing throttle on the stockplenum is a bad idea. but then it was put to me that when the manifold is under boost pressure it shouldnt matter any way. still not a good idea thoe.

kiwi32 Posted February 6, 2007 Share Posted February 6, 2007 For those who want a longer cable for there forward facing plenum. I used a throttle cable from a u12 bluebird with an sr20de in it and it fits perfectly.

tommyb Posted February 6, 2007 Share Posted February 6, 2007 For those who want a longer cable for there forward facing plenum. I used a throttle cable from a u12 bluebird with an sr20de in it and it fits perfectly. just to let u all know not to do the front facing conversion on the factory one i had one on my car they dont work at all as the other guy said the air flow goes straight to the back and goes in the back cylinder there for the back cylinder is putting in twice as much fuel and air then the others. thus in this wears out ur motor and use alot more fuel and gives u lest horspower Link to comment https://www.sau.com.au/forums/topic/154299-custom-plenum/#findComment-2884916 Share on other sites More sharing options...
