Great...i love mine. I have the SOHC civic one...it uses a IHI ball bearing turbo that's a little bit bigger than a T25. It hits full boost very quick and pulls hard. The fitment of all the parts was PERFECT, i didn't have to cut/weld anything and it all bolted together great. The piping is awesome looking and i have nothing bad to say about the kit except for it doesn't come with any fuel management. I got mine very lightly used for 1600 with gauges/bov and some other goodies so i can't complain about the price. If you got the cash i reccomend it, but if you don't there are plenty of good alternatives.
