Hi guys,

I've done a search for this but wasn't able to come up with much so I'm just wondering if anyone on here knows what the advantages are of upgrading to a forward facing plenum in a 33 GTSt.

From what I understand so far the advantages are shorter cooler piping (less pressure drop) plus colder intake temps. Is there anything else I should know and what have ppls experiences been (ie is this a good value for money mod).

Most ppl on here seem to upgrade to a greddy branded product but are there any other good alternatives out there for the GTSt? (eg GTR plenum)

Last question is how defectible is an aftermarket plenum in Victoria. Due to the "one intake modification" only law I would have thought that this would make it very difficult to get a defect cleared due to the fact you would have to put the stock plenum and intercooler back on.

Any advice/experiences much appreciated

Regards Taso

all up i probably have 3-4 ft of fmic piping-PRO

looks cleaner, ^^^^ easier to access plugs- PRO

its a bit cramped down the side, so getting to the oil filter can be....difficult-CON

you can upgrade to a larger t/b - PRO

you can delete the BOV- PRO

No and no unfortunately.

Legalities wise, as per the first post, he cannot upgrade/change those two things

Plenum i do believe you can change, as long as you keep ALL the factory bits on the plenum side to do with emissions.

So stock T/B, all hoses, breathers and whatever else is there... BOV included. Or just put a GTR BOV on, thats also legal as its plumb back.

Also...

I made 270rwkw on pump, 370rwkw on fuel (and more boost)... stock top end (minor head touch up) and my response was as good as any other car with a 600hp turbo.

Overall... honestly the money is far better spent on a turbo and other areas.

Especially in Vic. A plenum just makes the cops look harder

bloody hell VIC must suck ass... only one intake mod haha

On a relatively stock gtst its not worth the upgrade, money is best spent elsewhere. It does clean up the engine bay alot though and shorter intake piping is always going to be a winner

Thanks for the info guys, very useful indeed. I guess the reason i wanted to do it was because it just makes the engine bay so much tidier and its such a waste having the cooler pipes bending around.

Why couldn't nissan have fitted GTSts with FMIC and front facing plenum. MAkes my blood boil, would have saved us so many headaches

I'm thinking that shorter cooler piping would improve the response of the car?

Can anyone confirm/clarify this? This is the next step that i'm looking at doing - upgrading the intercooler and getting a forwards facing plenum as my goal now is to increase my response as est as possible for the setup.

So, for all those with a forward - facing plenum - did you guys notice better throttle response with the shorted cooler piping?

cheers

They did it to the Silvias, front facing plenum i mean, and had the I/C piping looking like an aftermarket GTSt!

In they end the engineer the car do produce certain power. And an SMIC is sufficient for the power they make in standard mod/boost form.

Not worth it just for looks, or bragging rights. I have one just because I did the 3.0L conversion, not sure if it improved throttle response because of the other changes I did. If your thinking about getting a china manifold I'd think twice there too considering the gamble on quality and the lack of parts they supply with it (not to mention its fake)

afaik benno @ racepace can get a hold of the blitz adaptor plate to put a GTR plenum on a gtst... still a lot of work tho

imho not worth it unless you are really concerned about cosmetics or have a spark plug changing fetish

    • 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.
