DP/exhaust = boost creep?

[BLUDVL6]

Ok guys, i've searched and read for hours about boost creep and all i want to do is tell you the setup i have and get some input. I dont wanna start a long thread about how i should have searched more and all that. Just a couple helpful opinions. I have a 3" o2 eliminator downpipe. after the downpipe, it necks down to about 2.5 for the cat-back. I am still running a cat and muffler. I'm about to buy an evo 16G cuz my T25 was beat. whats the verdict?

If you get a 16G with the bigger 34mm flapper and if it is ported then you shouldn't creep. It is a possibitly even after that. I have an 3 in O2 elim on my 14B for now and it would creep like crazy. I ended up removing the divider between the WG port and exhaust port and that cured it. If you have read all those post i am sure you have seen a few different ways to cure it. If it creeps use that knowledge to fix it.

2.5" O2 elimiator with flex, 2.5" test pipe, 3" cat back is the best setup for an internally gated B16G. The 3" DP will flow to well and the WG cannot keep up causing boost creep. I would go with a 3" with a 50 trim though because the WG is bigger and more efficent.

can you direct me to a good 50 trim....where's the best place to start looking at those?

Some might say PTE, btu I am nto a bgi fan of those turbos. I was looking at those for awhile and found that most people didnt like them. AGP www.agpturbo.com is great. Check out that sight. They have hybrids, and a full Garrett kit that kicks ass. Once i get some shit sorted out I will be getting a full Garrett kit from them. FP www.forcedperformance.com has the Green. It is one of the most proven turbos out there. It is a bit more than the other but like I said it has a good track record.

You will also need a FMIC because of the desighn of the compressor. It has a down feed(meaning the air exit points down) unlike the 16Gs points up.

not to mention that a 50 trim would kill a SMIC after one good hard pull.
