Upgrade to LS6 intake or no?
Upgrade to LS6 intake or no? So I'm nearing the completion of my twin-turbo project with my GTM. I wasn't planning on doing anything to the engine at first because I will just go forged later. However, in order to get the oilpan out of the car, I had to remove a lot of things, including the intake manifold (to get clearance when lifting the engine). I got to thinking whether or not to upgrade the intake manifold to the LS6 or not since now the intake is removed.
Think it's worth it or just hold out for when I change to a forged motor? I was at 333rwhp/331tq when it was tuned and N/A. Hoping for around 500'ish when I'm done, and once forged, who knows.
Currently a 2001 LS1, bone stock
Twin 6266's
7# springs in the wastegates
60# injectors
Kooks longtubes
TL;DR version (LS6 intake on a twin turbo worth the upgrade or not?)
Picture for good measure:

Your setup looks real nice, "but" it sure would have been been better to mount those intercoolers outside of the engine compartment. They are going to get heat soaked pretty bad...
But again really nice looking setup!

Depends what you can pick on up for. They are worth about 20-30 at the flywheel on the articles I've read. That will double at 15lbs of boost. So if you can grab one cheap and additional 40-60hp sounds ok to me. I just can't ever find one for what I'd consider reasonable. 
I will seriously look into relocation up and off to the sides once I swap the motor. That will involve moving the PCM, modifying the harness, etc. So it's a relatively big chore to do with the motor installed. I have a pair of intercoolers that would tuck nicely up into those spots, but on the passenger side, the PCM and accompanying modules sit there.
Baby steps.
Here's Nic tuning the car a few months back:
Yeah, I used to work with a company that does very elaborate, expensive heat management materials. I am thinking of working out a deal with them. I also want to run some sort of heat shield to reduce the direct heat exposure.
Edit: Just read up on this. Holy crap thank you. I'm glad I didn't just drop $450 for nothing.
Yeah, unfortunately, real estate on the car is VERY limited. I actually have 9 different intercoolers sitting in my garage that I have purchased and tried in various iterations. I do have a box full of heat wrap, heat shielding, heat management products too. Heat in the engine bays are a problem in these turbos or not, so it's certainly just going to get worse. I plan to add meth injection at some point as well as I had tremendous luck with that on my Typhoon. In the Typhoon, the water/air intercooler sat right over the downpipe and had heat soak issues as well. The meth injection was great, had 90 degree intake temps on a 115 degree day at 26psi.

Amazing car and build... I would love to build one some day! In the dyno vid it looks like the rear wheels are seeing a LOT of tie rod deflection under WOT with good traction. It becomes very obvious when he lifts the throttle. It may be worth looking into beefier tie rods or at least sleeves, especially with your higher HP goals. Keep the updates coming.
