Hi guys,

I wanted to take some time for those looking at sequential transmissions and show you what goes inside of a purpose built unit, not just a conversion piece.

This is the same unit we have been running for seasons in GrandAm and very similar to the larger unit featured in our ALMS GT2 Corvette, and the very SAME unit you can buy for your own project.

With over 45 different gear ratios you can custom tailor this box to each track and your car for the ultimate in close ratio gear boxes

These are all built to order and come in almost 20 lbs lighter than the OEM gear box and feature pressurized, filtered oil to all bearings and gears. Straight cut gears with of course replaceable dog rings for engagement.

Assembled main case


Tail shaft removed showing reverse gear


Comparison of the reverse gear to the main gears
Notice how much wider the forward gears are


Shift forks, notice they are gun drilled and feature pressurized oiling passages


Look inside the main case. Notice the large roller bearings and also pressurized spray bar for oiling to the gears


Main gear cluster


Huge main roller bearings for main shaft and counter shaft


Main shafts and shift rail


Gun drilled main shafts, again with pressurized oiling passages


Main shaft support bearings in place


Built in oil pump


Fine micro filter assembly


Oil pick up tube









As you can see it is more than just a face plated, or dog ring gear box T56 that goes into each one of these gear boxes.

While they may not be for everyone, I hope this shows you a bit more info on what goes inside of one of these awesome units! Feel free to hit me with any questions you have!

Cable shifter?
Pneumatic paddle shift option?
No lift upshift with stock E38 or E67 ECU?
Revmatch downshift with stock E38 or E67 ECU?

Any helical cut gear options for more road orientated cars?

0Anthony @ LGMotorsports

No....part of the strength in the box is the straight cut gears.

0Anthony @ LGMotorsports

It uses a shift rod assembly, no cable can shift it.

The stock computer can not do it, but there are add on boxes that you can tie in to for flat upshifts.

There is a paddle shifter in the works and auto blip on downshifts and cut on upshifts.

Cool video from a customer's ZR1 that just installed the Emco in their car.

Flat shift was not hooked up for this video, so you can see even without the added electronics just how quickly you can shift this vs a standard 6 spd.

That is AWESOME, Anthony. Man, that is a highly modded ZR1. Lexan rear window, etc. Very cool. The flames shooting out around 5:50 of the vid are greatness.

0Anthony @ LGMotorsports

He has our GT2 splitter, Emco box, lexan rear window, billet drop spindles, sway bars, carbon clutch, Super Cool Radiator, ForgeLine wheels, louvered hood insert, slicks....and a few other modifications.

They have done almost all of the work to the car themselves including the cage on it.

Killer car, and we have more plans for it this year as well.

QUIKAG

I can't imagine how fast that sucker is. He was moving it around that track very nicely. It is clearly modded engine-wise too as stock ZR1's don't shoot flames out the back.

You need some more LG parts and you will be fast too

QUIKAG

Yeah, I probably do. I'm trying to see how much mileage I can get out of my almost totally stock ZR1 (besides brake fluid and Finspeed wheels/Mich slicks).
