L32 heads on L67

Aaron, I will agree with them that a stock Gen V supercharger is much better than any ported and polished Gen III supercharger.

Don't confuse that with the heads from an L32 vs heads from a L67. Not much difference there. Just port and polish the L67 heads.

So if you want a decent setup, stay with your L67 heads, go with a Gen V supercharger. To do that you will need a lower intake and fuel rails to go along with the Gen V.
 


There is no saving this thread from mis-information...

all s2/s3 heads are the same....

Gen5's are better for a few reasons.

If you're using the L67 heads & TB, is it necessary to use the L32 fuel rails when using the Gen V charger and LIM? Based on all the information I've read, wouldn't you need to match the fuel rail to the heads?

I'm not sure. I first posted that you couldn't use the L67 fuel rails. But maybe you can. I never did the swap. I just researched it when I was interested in doing it. So I will delete what I posted and say I'm not sure.

I was curious as to why the L67 fuel rail wouldn't fit on the L32 also, but I see it's just a height issue. I have ZZP modded rails so guess I'm good. It sounded like there was a different bolt or injector pattern the way it's talked about.
 
From what I read, the L32 injectors are a different size to account for the higher pressure of the returnless system.
