Default ls6 90mm mod

Anyone have any good pics of this? I know TPIS puts the 90mm on the ls6 for you, but I don't wanna pay 350 for them to do that. My plan is to buy a ls2 or l76 and cut the TB outlet and mold it to the ls6. I have yet to compare the two side by side to see how much of the neck I will have to take off. Having the neck off will also allow me to do some port work as well. What would be the best way to secure the new TB neck to the ls6 intake? Plastic weld? JB weld?

I think the way to go is a 85mm and just bore out the ls6 throat as much as possible. seal with RTV

As stated do the 85mm or nothing. By the time you hack up both intakes you could bought a better intake for less

The TPIS 90 LS6 has been Proven to be almost 20 rwhp better than a LS6, basically equal to a stock unported FAST. If you buy a LS2 just to cut it up your already $200+ toward having it done correctly by TPIS.

I'm just looking into it. I've seen ls2s go for 120. I'd rather do it myself than pay a shop to do the same thing.
