The Unicorn: Abandon all Hope
 
As I am bored sitting waiting for IT to fix the upgrade they did, lets make a build thread for all to see. :nod:

In the beginning there was X, small older Precision turbo, pt76gts, 76mm T4 unit mounted on an old realquick turbo kit.

The motor is composed of a LT1 block .030 over, compstar 6 inch rods, compstar 3.75 forged crank and JE extreme duty forged pistons, all topped off with max ported stock castings, and a single plane.

Its controlled via a LS1 0411 PCM, so coil packs and 3 bar SD tune. Harness is a frankenstein'd stock LT1 harness with tweaks to use a vortec distributor for cam signal.

Built 4L80e and a S60 puts the power to the ground. Nothing extraordinarily fancy, but nothing remotely cookie cutter.

Take your antidepressants, and fall down the rabbit hole.

that wiring harness inside is crazy!!! lol. where do you have your coils mounted? I can't find them

Mid first post, they are where your sway bar brackets would be.

NJSPEEDER 03-30-2015 01:27 PM

What is that dizzy replacement you used as an ignition pick up?

V 03-30-2015 01:31 PM

wow, I didn't know it had that issue and was torn down.
Looks good painted too, lol.
Glad it all seems to be doing good again.

Just standard distributor out of a vortec motor, minus the cap/rotor part.

Yea, unless you ventured into BH :wink:

Thanks!

Nice to see it all come together outside that dizzying build thread! Really came together on the second rebuild!

As usual, the pal of pals comes and lends a helpful hand, thanks again Adam. :)

LTb1ow 04-16-2015 01:52 PM

If anything it would get an LS1 camaro dash upgrade, but thats far off.

Good to see she's up and running again and looking pretty damn good I must say

Pushing to get it all buttoned up and driving normally for the meet next weekend.

Nice. Hopefully I'll make it out to circus before I have to go to work

LTb1ow 04-21-2015 07:12 AM

Changed out the oil today, prob a little early but needed to get the assembly lube out and verify no leaking coolant internal. Thankfully it all came out crystal clear :lol:

Pulled #1 to get TDC compression, and plug looks damn good to me.
https://fbcdn-sphotos-c-a.akamaihd.n...d855531d84b662

I reclocked the dizzy, it was way off, and really need another person to fine tune where TDC is so I can clock the dizzy well.

NJSPEEDER 04-21-2015 11:52 AM

How far off is "way off", are we talking way off in engineering precision terms or way off as in wondering how it even ran?

LTb1ow 04-21-2015 12:12 PM

The dizzy is used for start up efficiency improvement with this setup, and nothing else. It will start and run with it unplugged AFAIK. Right now its got a window of +/-7 degrees I think and I am not in there. Basically causes backfires during cranking cause the PCM doesn't know what bank is where and it will switch to the other when it detects no increase in RPM.

Previously, my dumbass figured TDC meant, ya know, top dead center mark on ATI was, top dead center when looking at it. So, way off, is like 30-50* of crank rotation :lol:

Do you have a piston stop?

LTb1ow 04-21-2015 02:01 PM

Negative, this whole mechanical timing mayhem is a dark confusing world to a EFI LT1 person :lol:

And with that gents, the ****er is back to semi decent looking status! Wrapped the roof and sail panel with some shiny black vinyl, shameless plug for the company who hooked me up. Amazon.com: UNDERGROUND DESIGNS: Automotive

Super excited to have it all shiny, big thanks to Taylor for helping wrap it and Adam for getting the shift cable adjusted with me. Almost back to DD status, hopefully drive it to work tmmr. 8-)

NJSPEEDER 04-22-2015 07:03 AM

WOOT!!!

How long until you are confident enough in it to make some passes?

LTb1ow 04-22-2015 07:05 AM

Got another week or so of break in miles, then I will start datalogging and bounce stuff off tuner. If he says go for it, I will go get kicked out of Etown. :lol:

NJSPEEDER 04-22-2015 09:07 AM

Sounds like a good plan.

Are you going to be able to get the appropriate safety equipment installed this season or are you mainly targetting just being able to drive and enjoy it again?
