Twin 76mm 383 LT1 build thread
Well this thread has been a long time coming. I used to be a member on this board a few years ago, however I forgot that accounts login. I started a Single 76mm kit from Lt1 boost for my 95 z28. At the time it was just a LE2 hci bolt on LT1. I got about half way through the build and as life goes I got laid off from my job (which seriously impeded the building funds). Long story short I was unable to find real work for two years. I had to move twice, which meant the car, parts, and the entire garage had to be moved as well. What a Pita! Im still looking for parts I lost lol. Anyway I have a real job one again so back to the garage I go! Oh yeah somewhere along the way a second turbo got thrown into the works.
So here are some of the details on the car. 95 z28, fully built 383 shortblock 9:1 comp with le2 heads and intake, custom ground turbo cam, twin pte 76gts turbos on e85. Suspension is all tubular adjustable from spohn, k member, torque arm, lca, panhard bar, sfc's, ect. Strange 12 bolt with 3.08 gears and a spool. The Molly ds is connected to a built pg with a tb a 4,500 stall. Big and little Mickey Thompson rims with 325 et streets for rubber.
I am still in the process of fabing up the new turbo system. The headers are from Johns kit everything else is being put together by me. (John I hope you are not pissed that I canabalized your kit to make the new setup!)
I just wanted to start this thread to keep me motivated, ask a few questions, and share some Pics. Hopefully I can figure out how to upload them from my phone.

Here are a few Pics for you guys.
Of course the turbos.
Making the 2.5 in pipe fit inside the T4 flange. They went together so easily I swear they were made for each other.

Fabbing up the first turbo.
Fabbing up the frame for the new radiator. I had to move it forward to clear the turbos.
Keep in mind that all my welds up to this point were made with a 100 dollar 110v flux core welder. I just recently got a decent mig welder. The finish welds will look much better.

How the turbos sit as of today.
Making holes for the exhaust to run out the front facia just in front of the tires.
Drivers side is complete.
I think I am going to paint the exhaust and trim ring in high temp black header paint and maybe get some nice polished stainless steel hardware.

I love it!! im a sucker for symmetry when it comes to twins...offset turbos are just like a pair of lopsided breast you're glad to have em but you would like both to look the same.

Twin 76GTS?! Dang... what are you looking to end up with HP wise? Great looking setup btw. I see there's no intercooler intersected in that kit. No room or no need?
Congrats on being able to pick up the job and resume your project!

Thanks guys I really have no idea what I will end up with hp wise. The motor is pretty built but it is still a factory LT1 block. It was hand picked and sonic tested so it is about as good of a factory block as any. I guess it just depends how much I want to push it. No ic because e85 is awesome!

The next piece of the puzzle. Just came the other day! I am planning to repin my harness because I am not shelling out 800 bucks for a new one.
