found a company that ports and polishes intake and ports throttle body for $325. has anyone ever had this done, and if so is it worth it. thanks. fyi the company is peak speed shop.

i am actually thinking about getting one of their setups as well.

No benefit to porting an LS6 intake, don't know about the TB either, but you will sure sound like you are making more power when you put it in your sig.

well do the math 325 you can sell your old manifold for about 200$ thats 525 and you can find a used fast manifold for 700-800$ do the math and see if its worth it

what he said^^^a used 92 fast is in the 700 range. The one guy is selling a ported Fast intake tb and all the works for under a g...that should add 20 ponies or so but anything else is a waste in my opinion. But im all about going FI unless its a stroker NA. Regardless if you buy a used FAST you can always resell it later because there is always a demand for them, so its not money down the drain.

Hey Tony, at what level of head flow rate would you recommend a Fast 102? I plan to get some trickflow 220 heads for my LS2 and have my 90mm TB ported, most likely by you along with the Intake, but Im undecided on whether or not to track down a 92 or just outright purchase a 102. Im leaning towards the 102, reason being is because the 102 is the most refined design, works with my LS2 fuel rails, etc.....

Here is Tony's response:
A stock head can benefit from a properly reworked FAST.....the 317 heads in the comparison I linked above might flow 255 CFM's or so (they were bone stock....unported heads). Your heads flow alot more than that.

The better the heads the larger the gain from the swap as I have mentioned previously but your combination will certainly benefit from the better manifold.

Go 102....its a much better designed intake out of the box and due to its different build/construction design allows me to port it differently (allows me freedoms with the grinder I would have put a hole in the former 78/90/92 series) which compounds the gains even further from the swap. On a really good combination my ported 102 could be worth 10+ more HP over one of my former ported 90/92 intakes (which were no slouches and typically worth a 20-25 RWHP improvement....even more than that if the baseline intake was a LS1/LS2 manifold).

Shoot me a PM if you have an interest in getting something going or have any more questions related to your particular build.
