Project Rexige... Lotus S2, K24 Turbo + sequential project
Discussion
Well... progresss has been slower than I would like... but the engine and box I am assured will be ready by the end of this month...
New longerons, more gold sticky back plastic, new subframe... Aim dash mounted, fire systems, new battery cable and battery moved to the front, heater deleted... a fair amount done... just need an engine, gearbox, plumbing, loom and mapping now (just)...

Anyone want to guess what power it might make?
Getting closer... almost time to fire it up for the first time, both exciting and totally nerve racking.
I’m almost glad I’m in another country and cant be near it for first start up, brand new never been run engine adds an element of (wallet) fear to the mix.
Yep... I think the numbers here are about right, I’ll be gutted if if doesn’t make 500+ at the wheels, power graph to follow in the not too distant future (I hope!)

Many things have happened since I last updated this thread.
Engine is running, had a bit of fun and games with the gearbox, but mostly just learning how to set them up really...

All now working.
I have a list longer than my arm of stuff to finish configuring on the dash/wheel/PDM/ECU...
