aint that the truth. i know someone who got sold a second hand sc38 that was supposedly low miles and less than 6 months old. Considering that spec had been phased out 3 years prior suspect someone was telling some porky pies
As above, need to define what you want or budget.
Sc42, fuel pump, injectors, front mount, syvecs will see 400 but prob be £4k if bought new. Second hand parts and map will be cheaper but need to find decent parts. Decat and Remap will see 330 but only be about £1500 give or take
woudln't be the first time i;d seen issues after a backbox change. map will be to the setup it was set for, they dont take to change that well unfortunately.
GB270 as said is just a fancied up wrx so waaaay overpriced.
My advice with the budget you have, get a cheap run around diesel and then spec c weekend toy ;)
scary thing is i dont think you'd get a 22b for 50k now :o
Even in japan they are daft money, last one to sell was a ropey high milage one (180k or summit daft) and it went for £70k :o
