Black WS6 with single Holset +E85
Its currently SBE ls1 + t56, with 228r cam, ported heads, dual valve springs, chromo pushrods, double timing chain, mellings oil pump and so on. With holset hx55, running about 8 pounds of boost now. Its been boosted about 15k miles now, maybe more.
I have no idea how much power it have, i tune it by myself with hp tuners, so no dyno pulls, but it goes like a maniac. Smoking 315 tires still at 3th gear, if the road is even slightly cold, it wants to go sideways at 4th. First it was fun, now a little scary, so i started to build 9 inch rear, so i can use some grippier tires (stock 10 bolt with 4.11). I'll make it myself from laser cuts, will be posting pics.
I will post more pics soon.

And the turbo is holset hx55.
I will post more pics soon.

I'm having a problem with the pics, every time i try to post a pic, it needs approval from admin, because my low post count (i'm a new member).
Btw, i have seen lots of speculation about these holset turbos in ls engines, and for my experience i love it. This is (for now at least) 100% street car, so i have no idea how will it work at track car. But at street, it is brilliant. Makes LOTS of torque and spools quickly and will not run out of breath even at 12psi @6000rpm. But if it does someday, i'll just buy a bigger one. Very very nice and fun thing to drive.
I will try again as soon as i get home. Yes, me too. They are dirt cheap, reliable and the spooling sound is LOUD. I have full exhaust, so it sounds like a jet plane ready to takeoff. 
Thanks man.
