LS6 Conversion

I know LS6 heads will bolt right on to an LS1 block but can I use my LS1 intake as well or do I have to go to an LS6 intake? I know an LS6 intake would be optimal but there is only so much money in the bank.

Are you getting ported LS6 heads or your out of the box 243 castings?
Look at these 2 threads FYI before caughing up cash for stockers:

You can use the ls1 intake with no problem.

Yea, you can use the LS1 for now and just upgrade it later. It'll hold your new heads back some, but it will get you by.

Replace with an LS6 or better intake ASAP.

I made 343 rwhp with an MS3, lid and full exhaust on my A4. Upgraded to an LS6 intake manifold, added an SLP underdrive pulley and a retune with the intake/pulley landed me at 385 rwhp. That is a 42 rwhp net gain. Given that a pulley is worth about 10 rwhp that may or may not show up in full on a dyno that's a minimum gain of 32 rwhp from the intake. That LS1 intake just doesn't flow well enough and will probably choke the crap out of your top end.

Thanks all for your responses. Yep I realize the LS6 is optimal but like all of us at one time or another i'm tapped out.

Spending money on heads/cam with the stock intake is not getting the most for your money. An intake is so much cheaper than heads and/or cam why spend the money for heads/cam and have a stock intake that may cost you a large percentage of what you would otherwise have?

Look at my example. Why spend $1,350 for a cam/spring swap and dyno tune to get 343 rwhp (A4) because of an LS1 intake manifold?

Just don't be dissapointed if you have very poor horsepower numbers until you get a better intake on there.
