Your not going to find too many guys with the SFR kit, mainly due to being custom built to order and not highly advertised like other FI kits. I have the SFR 60-1 TT kit, tuned very conservative ( still on stock motor ). Car runs perfect with no problems at all. I chosed this kit, main reason was SFR shop is only 20 miles from me. Convenient to have a shop install a kit they know very well. I have a 5AT, so I had them rebuilt/upgrade the tranny as well. SFR is not just a regular performance/install shop, they can build and custom fabricate anything you want. You got the money they can do it.

If you talk to Tim about your HP desires/goals, ... he'll be able to give you an idea which turbos would suit your needs. If you can shell out the $$, go with the ball bearing option as well (IMO). Check out http://www.turboneticsinc.com/turbo_overview.htm since he uses Turbonetics turbos on the kit, ... there are tons of choices.

So to directly address the comparison to the Greddy 18G turbos, ... the 18G-5H turbos are rated about about 400hp each, ... so figure 700-800hp total for the Greddy kit. That's not too much less than what the pair of 60-1 Hi Fi's are rated for. If the Turbonectics turbos are ball bearing, then they should have a bit better spool, giving you an earlier rise in power...
... throw in the fact you could practically choose another turbo to go with the SFR kit that is very similar to the 18G's 'if you wanted to do that', and i don't really see an advantage/disadvantage other than the fact you have the choice of the ball bearing upgrade with the tubonetics turbos.....
hope that helps a little bit

How much boost are you running? How long have you had the kit? Daily driver? Totally understand the local shop deal, was the kit pricing competitive with the others on the market? Do you have a dyno sheet? Can you hear the oil pump? Sorry for the 20 questions, I don't see these things being reported which makes this kit mysterious.

These add ons you mentioned - UTEC and ball bearing option. How much more does that make the kit? Built Greddys, built APS, built JWT 700s seem to put down a decent amount of power. Has SFR maxed out their 60-1 kit yet?
well, a lot of the guys with this kit do not 'live' on the internet, ... so it is kinda hard to get a lot of the personal impressions we all want.
Anyhow, to say when any of the other kits would need to be 'upgraded' is not really the point I guess, I only compared the 18G's to the 60-1's b/c it was directly addressed....
... BUT, that being said,
If you had a built motor and wanted a friken bad a$$ drag car friday night, you may want bigger turbos, and then for Autocross the next day you would most likely not want the same turbos that just got you into the low 11's the night before... 
I say ALL of this with the assumption that a car like this would be "well rounded", meaning aftermarket sway bars, coilovers, camber adjments, brakes, buit motor(long or short), good engine management solution, fuel, cooling, etc, etc.... So in a case of someone that is more than willing to swap turbos out like that, ... it's more than just 'driver or suspension' that makes an impact given the huge range of motorsports we get into....
I'm not aware of anyone 'maxing out' the 60-1's yet, ... but i'm not exactly 'in-the-loop' being in friken Iraq...
as far as price,.... these kits are taylor made, so you don't pay for what you don't need (EM, fuel components, etc). So price is definitely on par with every other offering out there....

Rookie,
were you able to fit the adjustable coil overs on your FX. You got them from Taiwan right correct me if I cam wrong..
how is your tranny holding up after the 400+ HP.. still doing some adjustments? what kind of adjustments?
I am really curious about the coil overs.. as H&R and Eibach only lowers our by 1.2 -1.5'' if I remember right.. I am planing on going lower also by switching to 19'' Volks or Iforged..But also need some good lowering springs over coil overs..
Any thoughts on thaT?

I think what I will do is
Change pistons, rods, bolts.. somesorta kinetics intake with the turbo set up.
that way I ll keep the same displacement and avoid the heavy beating taxes here ..and keeping the cam so I dont get into extreme tunig issues.
At SFR.. 3 types of turbos.. larger, medium and Greddy size 40s.. cant decide on which one to take..

You reminded me to get open the box up and take some pictures. I have not installed it yet. Maybe in the next few months.
Here's what the kit looks like.
