Avensis T25 2.0 VVTi 1az fse Mods Upgrades Tuning

[Margoram77]

Hey guys. I'm in England, the midlands have a 2.0 petrol manual looking for mods, upgrades, etc. First point of call suspension, coilovers, then some new rubber & probably brakes. Pretty rusty underneath anyone know if subframes from the diesel are the same for both cars? Also anyone know if the driveshafts from the diesel are beefier & compatible? Anywhere good for parts in UK? All help appreciated.
Cheers
