So the shitty running on the T5 turned out to be a little air leak

running well again! Although I've been looking at what obscene prices you can pick up things like CL500's for and has got me wondering!
Little update, got one side of the coilovers all bolted together which I'm happy with, feels like some real progress! Now to strip down and blast/paint along with the other side.
Rear springs turned up which was the only thing stopping the rears being done, although I'll be pulling the axle first and fit all the poly bushes and make an adjustable panhard bar.
Been looking into a wasted spark conversion as the standard ignition is okay at best. Also potentially Megasquirt but I'm unsure yet.
