Killer-T on the W.A side of things can tell you he had one recently.

Definately PM him.

r u sure u wanna get one of those cauz ul lose ur climate control if you do..

[Craved]

Jigga,

why would the climate control be affected by the new plenum?

[Jigga]

thats what i've been told?? by the manufacturers of these plenums eg subzero, micks metalcraft and mr enforcer..... they don't have the features to accomodate climate controll etc.. cauz they also use larger throttle bodies aswell which arn't nissan, some manufacturers jus say these plenums are for race applications y would u want climate controllwith a car that modified, i don't know bout the greddy plenum though??

[BOOSTD]

You loose ur Idle up valve that helps your car idle when the air conditioner is on.

[GTS-t VSPEC]

Yeah, the idle stepper control is lost, but not a huge deal. Can make it harder for cold-start though.

[BOOSTD]

thats alot of posts. OMG

[GTS-t VSPEC]

Yes, but that doesn't mean I know what I'm talking about:D

[MetBlue_GTST]

I've got a Sub-Zero plenum on my car... Inside the plenum is big bell-mouths at the top of each runner... My climate control works fine... I'm running Autronic in my car and have no problems with cold-start...

[GTS-t VSPEC]

Alan, Lumpy couldn't figure out how to do it with a PowerFC though.

[MetBlue_GTST]

Whats that, the cold-start?? Thats probably coz the PowerFC requires the IAC valve there and has a big spaz if its not... I'll ask him tonight and find out...

[GTS-t VSPEC]

Yeah, but all he did was take out a bit of fuel and it started really well.

[Ronin 09]

so let me get this straight - even a power FC cracks the poos if the idler control is not there with the Greddy plenum??

[GTS-t VSPEC]

I have the GReddy plenum, and it has the idle controller there.

[B-Man]

GTS-t VSPEC , did the GReddy Plennum come with everything required ?

Did you use the factory throttle body ? I have and XF Throttle Body - will that fit the GReddy do you think ? or will I require an adaptor ?

How did the throttle cable go ? Did you need to replace or does the factory one work ?

Can you use top feed injectors ?

Are there any gotcha's with these or pretty straight forward ?

Thanks dude

[GTS-t VSPEC]

B-Man,

You can use the factory or XF throttle bodies, but they will require an adapter. The only throttle body that bolts straight on is the Infiniti.

Yes, can run top feed fuel rail and injectors, but I still have the side feed in.

We managed to retain the factory throttle cable, but has since been replaced for better mounting.

Other than that it's pretty straight forward, just takes time to get to the bolts:D

[Ronin 09]

B-Man, just another note that may help you, Greddy actually have an adapter you can buy for about 100 bucks through greenline that allows you to run the factory throttle. I believe the factory throttle is good for at least 400hp or so... but you may want to go to a 90mm or something - sub zero have them i believe.

[RIPS]

We do a R33 RB25det intake here, its not just a top 1/2, it has equal length trumpets, retains all the idle controlers, can run side feed injectors or with a kit, run up to 1700cc top feed injectors, can be made to run a Q45 throttle body or one of our RB25 throttle bodys thats been taken out to the same size as a XF, so you keep all your original tps plugs etc. We supply a throttle cable with it. They can be polished or powder coated. Price with manifold, enlarged RB25 throttle body (as per photo) and throttle cable is NZ$1500, thats not polished or painted. Regards Rob.
