What options are out there for replacing the stock manifold?

If it's the same as the cavi/sunfire/saturn manifold, then the venom IM would work. And as said many times before the gm performance IM will not fit on any stock eco, without pushing forward the radiator.

GM's intake is like 1000.00 and uses the LS1 TB

there was just a post on boring out the stock manifold I belive it was called "ecotec intake manifold sucks" it had some pics. it's like a 15 HP gain with little to no money.

Interesting! Guess its gonna be a case of getting out the toolbox and shaving plastic fantastic 4 the weekend.

BTW,
Dbilas do an alternate manifold and TB set-up for the Ecotec

Whoa! a speedster. Is the ecotec the same thats in our engines, like all of the parts?
If it is, an intake manifold will be really expensive for what it is. I've seen some companies that sell them, but they are all a custom order. I'm hoping there will be one that is under $1000 in the future....thats just too much for an IM.

Ecotec L61, different transmission.

The vx220 engine has electronic throttle and the exhaust manifold is different, otherwise they are the same engine.
Due to the small amount of space in the vx220 the GM inlet manifold will not fit.
The weaponR exhaust manifold can be made to fit the vx220 and gives good performance coupled with a Milltek system.
Try
vx220 for more tuning ideas.
