Intake madness!!!!
Intake madness!!!! So my build is LQ4 (6.0) with 80mm turbo in 81' Malibu. My madness is I've bought and sold no less than 5-6 intakes trying to make decision on what to run based on research. I've had trk intake,LS6,Typhoon,eBay aluminum high ram,and presently have LS2 and trk intakes left but just read hotrod magazines write up on top 20 LS intakes and now I'm thinking of going to TOSS one because the tests show it making good more power than any other stocker except LS2 (which wasn't in test). I'm going crazy over this and want to make final decision before it's time to bolt on and fire up. Suggestions??? Feedback???
Why are you worrying to much about the intake on a twin turbo setup?
If you can fit an OEM truck manifold go with that. Otherwise just stick with your current one and maybe get it ported. You won't notice a lick of difference on your setup between all those, maybe 5-10 hp. Hell, bump up the boost half a psi and you'll makeup the power difference between all of those...

Single 80mm, but your probably right with forced induction unless I'm putting out big $$ for fast or big edlebrock it won't matter much. Still wanna get best,or so my gear head says.

Verdad Gallardo You gave very limited info on the build but If its a stock LQ4 your not going to be able to run a ton of boost anyway, either of those intakes wont make any difference power wise. What are you doing for the heads and cam?
LQ4 stock block,polished crank,H beam rods,JE forged pistons,317 heads with nice valve job and head milled for straightness, compression 10.0:1,dual springs, LS9 cam,LS7 lifters, GMPP oil pump, ballet roller chain and gears.
Like I previously posted, I wouldn't be so concerned with the intake especially seeing your running stock heads and a LS9 cam which is definitely holding you back more then any intake you may choose. LS9 is good for a root type blower but there's far better turbo cam options out there.

Well aware, everything your doing I did 2-3 years ago on a old LS Fbody 5.3 turbo car. You don't seem to be getting the point. So your going to go w/ an inferior cam and leave 30 hp on the table for a few hundred bucks but your overly concerned about an intake which maybe differ a few hp if that from one another...anyway good luck w/ the build.

I gained significant power/torque swapping to a TBSS intake.
With my low 6200 RPM limiter and smaller cubes, I would likely lose power/torque across the entire rev range going with something like the Holley Hi Ram.

Good to hear and thanks for the feedback. They faired very well in that test.
