Custom Plenum

[cruzin33]

Iv got a custom plenum and i cant find where to put the blowby hose. I got the plenum with the car and im lost where to put the hose as im starting to detail my engine bay and keep on the good side of the cops. any idea where it goes or what to do?

Cheers

the plenum needs to get a nipple welded to it... so you can connect that PCV to it.

Just run it down under the plenum off the rocker cover thats what I did with the custom plenum cops wont know what there looking at

Dyno results before and after fitment?

[SKYHY]

dude were did ya get the plenum from... i want to get one as well

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

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]

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

thats the stock plenum with a cut and shut so the thottle body faces forward.

[ULOOOK]

As craved said, block it up. Mine is blocked, no probs.

i'm guessin you don't know what kinda throttle cable was used then??

Can anybody out there tell me what to use??

Bump, what throttle cable are you guys with foward facing plenums using?

[m0rt]

i have a mate with a rb30 in a vl and he is using a calais one, also had one guy recommend a silvia one, but i don't wanna be goin out buyin all these different cables if they won't fit

[Nobyz]

I turned my throttle body upside down so i can use stock cable

[GTR-90D]

whats better

a mass produced Jap cast plenum or a custom made one from local hi-po tuning shop?

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.

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.

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
