thoughts about 18G

[4G63Spyder]

I have a Mitsu 18G in my 99 GST, and the spool time is somewhere between forever and 5000 rpms. When I get to full boost (+/- 17 psi right now) she runs like mad, but getting there is somewhat more turbo lag than I expected...of course I still need to free up the exhaust a little more...going full 3" soon with a ported o2 housing as well.

Here's my prob...I have a friend willing to trade a ported/clipped 16G for the 18G. I know it'll spool faster, but is the difference worth it? I'm not looking to be an all out race car, just quick for the street (let's say trap about 105-110 mph range in the 1/4). In your (smarter) opinion, which turbo would you go with and why?

Thanks in advance for the help,
