Probably one of the very best street turbos for an FD. I can make 15 PSI by 3500-3600 rpm... 406 rwhp at 14 PSI... It rocks... If you're looking for a street turbo, excellent choice. If you want a pure drag turbo, you probably want something bigger.

Are you guys talking about the hks to4s or the turbonetics tso4. I was told very good things about the hks to4s. The hks tubo is $2800, thats too much for what i want out of the turbo.

hks uses garett turbines and modifies them to flow to their liking, atelst what i heard. both the turbonetics and the hks ones will produce this power. 2800 is the turbo kit not just the turbine, i think he was talking about the turbine itself?

As some one mentioned the turbo is good to get into the mid/high 10's. This turbo is great compromise between lag and power. As you can see on that time slip, aside from sleeping @ the light I could have ran a quicker 60' time. On that run I spun them through first, all of 2nd, and part of third. The thing in that run you should be looking @ is MPH, which is a better representation of power. ET will vary on more factors.
Hell I ran a 12.4 @ 95mph on this setup. But since that run was on slicks I had a 1.5 60' time and hooked like crazy in 1, 2, and 3rd. then almost put it in the wall so I lifted. ET has a lot to do with driver error.

Also not my Afr’s are lover 11’s on C16, I’ve been having shaky boost readings from not having any sort of damper for the Map sensor. So there’s still power left to be had..
Ohh boost comes on so fast I am probably wrong on my readings, also I found out how inaccurate my crap-o-meter gauge is. Ill have to do some testing with my defi gauge.
