Easy way to see how the maf is condition wise is to run the car then Unplug it if it stalls straight away then it's usually fine, if it keeps running then it's ****
Go for quicker spool, got to think will you be runing into 5-6k rev range on the road regularly or would you want it to get there faster without the need to be smashing it everwhere ?
Give dunc (racedynamix) a mail he'll come to you, if your willing to travel there's , Andy forrest in Scotland, or bob rawle Andy Carr or scooby clinic, have a read around as people have differing opinions on all of them
If they were falling apart yes if the were just worn maybe not, I put a new gearbox mount in at Christmas and it made everything nice and tight don't get half as much judder as I used to
My old one
Most likely be the droplinks (rubbish design) or anti roll bar bushes, could even be the suspension top mounts, but I'd doubt it, I've changed pretty much everything for new bushes etc and still get a dull thud/clunk from time to time,
I've no idea mate, try dropping savage bulldogs a pm he's taken then apart before, didn't realise you had to split the hot and cold sides to get at the pipes,
Trouble is with ours is the engine bay gets so hot the cone ends up getting heatsoaked unless you remove the resonator and stick it in the wing recess, wouldn't be ideal if your wading through big puddles [emoji52]
No worries mate, glad to be of some help, wideband lambda sensors are for monitoring air fuel mix, normally used when mapping although people fit them to highly modded engines so they can keep an eye on things before they go bang [emoji50]
You'll need bigger wheels to accommodate the four pots, i'd go with a panel filter not much point in going for a cone, unless your after bigger power, may be worth investing in a remap aftwr the exhaust and filter should see better mpg too
