Default Help Choosing A Intake Manifold

I have been trying to decide on what will be the best intake manifold for my set-up. My set-up consists of

98 ls1 with Mahle Pistons 3.9045 bore
Stock rods with arp bolts
PRC ls6 2.5 heads
Tick SNS stage 2 cam
BTR springs
78mm Fast Intake Manifold ported
78mm Throttle Body

I'm wondering if Fasts 102mm LSXRT manifold will work the best. I just can't make up my mind, with all the different options available, any help will be appreciated.

Well naturally the 102 will make a few more hp than the 78, but the question becomes is it worth the cost

Personally I'd save just a little bit of coin and sell your setup and opt for a 92/92 combo. That way you can reuse your injectors and rails, no extensions or anything like that. The 92 is plug and play.

As HCI2000SS has said, is it worth the cost to upgrade. This has been my dilemma, what if any would be the best upgrade for cost vs reward.

If you can make it fit the LSXRT is probably the best plastic manifold you can put on these motors.

It's going into a third gen camaro with a ls1 swap, so maybe it'll clear the hood. I think the LSXRT manifold will be my best option with some mild porting.
