What's the consensus on intake manifold styles?
 

I'm trying to figure out which way would be the best to go on intake manifold style for my street '00 Z.

A traditional 90/90 setup

or

A single plane EFI setup (small cowls are an option)

I'll be doing my own independent research, but if anybody else has done any and would like to share I would greatly appreciate it :)

if your going to do a single plane EFI, the best way to go is a 4150 TB.

that being said, both will net you about the same, however, if your sticking with a 90/90, the 4150 will give you more room to grow.

I was thinking about using an elbow. I'm not sure if it's possible to put an air filter on a 4150 from the looks of it.

sure there is....

Telling us your engine is a "Street" engine isn't nearly enough info to be able to help you. Give us a rundown of what a "Street" engine is.

The general consensus is that elbows on these car KILL power, so stick with the 4150 style throttle body or the traditional plastic manifold and use a FAST 102mm.

Id stick w/ the Traditional setup

For now It's just going to be a bolt on vehicle with the factory LS1. Nothing fancy. Looking for a setup that will play the nicest with a heads / cam job when that time comes.

So the consensus is - stick with a 90 or 102mm setup and avoid a single plane / elbow setup because the elbow kills the power. :burn:

yes the elbow does kill power, but thats why you go with a 4150 style TB.

That link you posted... Did the guy get to keep both of his windshield wipers?

yes, it can be done, just takes some careful triming and attention to detail to seal it. not a big problem for how well the 4150 performs.

Do you have any suggestions on which carb hat to use with the 4150?

The help and links have been greatly appreciated. :)

I went from a stock setup with bolt-ons to a BBK intake and 80mm TB. I noticed a slight loss in bottom end (still smoke em for 100yrds) but a good improvement in the mid range and top end.. Then went to a Victor Jr. Aarons elbow and a FAST 90mm TB and had no loss anywhere except an increase in top end. To each his own. Different setups will produce different results.

Is there an echo?:angel:
