I want this plenum... anyone know who made it?

[donniekak]

still waiting for someone to make these available:

Looks like it still bolts to the stock lower mani.

i'd take it either way. if this could be made to eliminate upper and lower plenum, i'd really be sold. even as pictured though, it's still my favorite plenum option for our cars.

Beautiful but is that the stock throttle body on there? Kinda defeats the purpose.

looks great......if you plan on turning 10K RPM.

last aftermarket TB i saw available for our cars was a horrible POS. dunno what else we can use. q45?

you're right...i do want low end power. can we start the runners in the back seat?

Believe me, i love the broad powerband of my 3s, compared to all of my 2 liter, big turbo cars. But, the refusal by most of the ownership of 3s's to go all out, has held the platform back. Just look at the 10 second 9b car. It's faster than 90% of td05 cars, just from having a singular purpose.

Anyway, it's not about where the power is, that's what the shifter is for.

The problem isn't cash. Plenty of people have dumped tons of cash into these cars. The problem is 2 fold. First, people for the longest time have refused to believe that universal building concepts apply to these cars. Second, it seems for the most part, that people with 3s's are afraid of a light car, with high rpm power.

reason 2 is why the skyline is a "legendary" car, while the gto is lackluster in the eyes of most.

we are afraid of high RPM power because our oil pumps explode and the transmission just flat out doesn't shift past 8K, not to mention the gear ratio just doesn't work for that. Both problems have been fixed, but guess what, nobody will do it anyways.

Anyways from memory, 12" gives best power at 5-6K RPM, 10" 7-8K, 6" 10-12K?
