Just wondering, I was browsing the internet earlier, and I know a lot of folks on here have been talking recently about intake manifolds and such. Well I saw pics of the new Monte Carlo SS with the FWD LS4 5.3 motor. It looks to have an LS1/LS6 based intake manifold on it. I was just wondering if anyone here had done any researching into the parts available from the LS4 and what if anything would be compatible, or an upgrade rather to what is available on the stock LM7 or L33. Just a thought, might not be anything worth doing the swaps or testing, but who knows?

Any specs on the LS4??????

 

From what I've read, it's slightly shorter (from trans to pullies) than the other LSx gen III and IV engines. Note sure of the cylinder/port spacing, but my guess would be that it's not going to be something we can use. I'll gladly be wrong though!

 

By looking at this pic:

It dosnt look like a high rise intake like the trucks but more along the lines of the LS1/6 intake. It does look to use the short MultecII injectors though.

 

lets keep our fingers crossed this one is a plug and play that flows well past 5500

 

whats the deal with the manifold? It has an extra thingy on the back. Thats a big EGR port!!!lol

 

hopefully we can get some testing done with this intake

 

probablt a crossover, if you are not kidding about the question

It looks very lsX, like someone said maybe it is plug and play , should be cheap to buy out of wrecks too.

 

the exhaust runs right under the tb on those things. can't be good for air temp.

 

is it just me or is the manifold bacwards? throttle body on the back of the motor, huh?

 

Yes it is, Remember this goes in a front wheel drive car. Everything is all bass-akwards, it would need some attention before it could be just droped in.
