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.

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.


JGS 50mm wastegate and JGS 60mm BOV

Kit mocked up at builders

Here it is clearing on my motor

Some pictures from when the motor was being built the first time around






Hotside coated, pre wrap

Milled and drilled for a MAP mount

RIP old cam

Early picture of semi assembly long block

External fuel pump makes more noise than a idling motor.

And since nothing is to be normal..

Early test fit of stuff

Torque converter, triple disk 3400 area stall

Rusty cold side picture

See the theme here?

Built 4L80e from Jake's

First attempt at mating all the parts

That theme again...

It all fits!

Vacuum lines for everything under the sun

Fancy pusher fans

Electronic boost controller

Coil pack mounted up


Scavenge pump for turbo and crankcase puke tank

Relay and fuse board, everything OE was removed from engine bay

First start up, pardon the mess of a harness

And of course, first drive

Not that its ever been used but created my own meth injection kit



Finally got some interior in her

Proof the car made it places under its own power

Engine bay shots


Got a blanket for the turbo

The first dyno passes

A clearly photoshopped dyno graph

The first attempt at a pass, alternator died and car lost all power

So after that debacle, ordered a new alternator

And went to town with heat wrap

That sums are part one of this novel, ended with a 11.5@138 and some snapped flexplate bolts.

Converter damage

Flexplate damage
