Forged Performance: Built Twin Turbo G35 Sedan
As far as the Cosworth Plenum goes, it is a VERY effective upgrade for a FI VQ car.

They are about the same on a naturally aspirated setup. However, on a FI setup they are significantly more. We have seen significant gains with the Cosworth manifolds on a build motor TT setup.
I think you mean this thread here
Unfortunately- not sure if it's just me but I'm not seeing any photos or graphs- then again it's a 4 year old thread. All I get are X's. Perhaps there's one later on or maybe it works for everyone else.
With that being said- sounds like by the way everyone is talking about it it's a worthy upgrade. Not sure about the V2 but sounds like the V1 shines on FI.

The only recent change I've heard of is the discontinuation of the cf end caps to billet end caps. Wish there was a recent comparison...maybe I can ask forged to do a comparison as they start this round.
I saw a V1 in the marketplace either here or in driver... Sounds like the V1 LOOKS better by a significant margin... whether or not it PERFORMS better...
I'd like to see that too! As it is with the guys who are buying it for looks- it's keeping the price on the V1s high.

Not sure I have any dyno graphs on hand. I would have to sort through our database which would take forever. We've seen very consistent results with the Cosworth plenums on FI setups, so it's not a 1 time deal where we saw impressive gains.
The Cosworth shows well documented gains on FI setups. On NA it only makes power above 6.5k RPMs but loses power before that, probably because on NA the air is not forced in like an FI setup so it takes higher RPMs on NA to show any gains.
And I would suggest the owner get some Forgestar rims with a custom offset. 19x10 +50 in the rear to fit 295s or 305s. Not more than 10" wide because he might not always find tyres wide enough for wheels wider than 10"s.

Terrible offsets for that width of a wheel/tire.

The idea here people, is to fit the widest possible tyres without rubbing for maximum traction. Hella flush is for idiots who upset the aerodynamics of the car and love curb rash because the tire is stretched to not rub because of the aggressive offsets.
It's terrible for a 350z or a G coupe. Actually stock rims on a sedan have a +45 offset and 7.5" wide. If he wants to fit 295s or even 305s and not rub he needs 10" wide rims with a +50 or +49 offset.
295s have been done on sedans on g35driver.com One had 9.5" rear wheels with a +49 offset running 295s and one had DPE wheels with undisclosed offsets running 295s.
That would be ideal on the front for a 8.5" wide rim with 245s. And that's probably what he has already which is why he cant run anything more than 275s because it rubs on the outside.
