Ls400 Trackday Weapon - Project

[AdeV]

A few weeks ago, an insane plan was hatched... my (much younger) colleague at work, who's dad is a keen banger racer, wanted a car to banger race. Some time ago, I bought a white MK3 LS400 with a number of common issues, but with a decent low mileage engine. My plan was always to stick the engine in my old Ford Granada, & dismantle the rest of the car to sell.

So, plan A was to simply let my colleague do the stripping down to shell, I'd sell the parts on fleabay, he'd get a free shell to banger race, etc.

As is normal in these parts, things got a bit surreal. The decision was made that, rather than just strip & banger the old girl, she should be allowed a bit of fun first. So, here's plan B in all its glory:

1) Strip pretty much back to rolling shell.

2) Add lightness, e.g. by chopping out door inner skins, bonnet/boot bracings, etc.

3) Fit Supra R154 gearbox to UZ engine, I also have the Supra prop, diff & drive shafts - although I'll probably use the Lexus drive shafts just to keep the standard brake fitment.

4) Fit a Megasquirt III + MSX ECU to allow full sequential ignition & fuel mapping.

5) Fit custom exhaust designed to run at 105dB @ ~4500rpm

5) Add 2 lightweight seats, harnesses, slick tyres, unassisted steering & race-spec brake discs/pads

6) Go scare the sh*t out of stuff at Oulton Park + other UK circuits

Photos as & when.

2 phrases: "How hard could it be?" and "What could possibly go wrong....?"

Sounds like a real hoot!

Brilliant :D Can't wait to see progress, you'll be amazed at how much weight is in stuff like roof linings etc

Loving #6 on the list
