Beautiful, what size is the elbow pipe?

If you have the money, go for the P11/Q45 (whatever its called) TB that G-Spec has. Every SR20VE with that and the regular bolt ons (N1 cams/springs too) seems to push the dyno numbers up in the 220HP+range.

Of course, it ain't cheap though and DIY is always more gratifying! Hell, you could probably even sell that modified piece to someone here if you ever decided to buy the Q45 one.

I was referring to this, I knew it had something to do with the Q45, but I guess we shouldn't really call it that: G Spec Performance - Plenum Kit, VVL (P11)

"The plenum is drilled for the factory throttle body and bolt pattern but comes pre machined for up to a 70 mm bore (Up to 80 mm bore available and custom bolt patterns as special order, call prior to ordering.) Add $25 for Q45 TB pattern, add $80 for N1 TB pattern."

The elbow is 3" which suits the plenum well and the tb is a 76mm piece. Will be mated to a 4" cai. I'll post pics once it's fitted. Getting the angle of the elbow moved tomorrow. It's pointing too much downward as opposed to forward.

Have some itb's sitting n the shelf but I want to play with the manifold first. Also have another bigger aftermarket plenum but don't think I'm going to spend money building runners for it. Will go to the itb's directly for now.

The xcessive plenum has shown to have 10whp gains multiple times. For the money it is a great option. There are better manifolds out there, they just cost more.

I am interested in this, Its nice to see some different options. I would like to take the xcessive N1 upper and build a custom lower to see what the gains are versus just the P11 xcessive upper. Then maybe a full custom mani on top of it all.

Cool. I'll look for some. I have 3" -wonder if 4" would be beneficial or be too large
