why dont you buy some tfs 245's and a 102 set up i think that should net you 50+rwhp

 

Well for me if its not going to net around another 100 rwhp then its not worth the time and money. I love the way the car runs now, it just kind of bugs me that I never finished the top end of the engine the way it deserves!

 

I'm at 600 with the TFS heads, and I don't have a 100mm maf.
I think the parts list you got from Shawn would make great power, but I think you could hit 600 with a LS7 intake as well.

 

Oh definately he could with his M6, now for a A4 it would be a little tougher but still doable............

 

leave the heads on and spend 1500ish on a ported 102 and you might net 30 rwhp thats worth it imo

 

That would still be over $2200 for 30 hp??? ported 102 fast, 102 throttle body, 100 maf, and dyno tune.

 

will my current comp cams lifters #850-16 work with the Ls7 top end??

 

Well with the fast intake and nasty performance fuel rails I can keep my current injectors so I'll probably do that.

 

If you get a 102mm intake for the TFS heads I'm pretty sure you'll need different rails, but nasty could tell you.
I made 600 with the fast 90/ls2tb and stock rails. After swapping gears the car dynoed 590. With a 102mm fast it went back to 600, but we haven't tried the 102mm TB yet. I got Nasty rails for the 102 intake and my understanding is that they were different.

At this point you should get what you want and have no regrets. I don't believe there will be a huge difference in total power. I think we're more at the limits of the intake than the heads. I've seen TFS 235's make the same power as my car.

 

I would have to agree with all of the above statement........

 

You can bet shawn will recommend performance inductions heads. Some of the best you can buy!
