Back to Landy madness again

Hi I used to have a 110 2.5D (NA) Ex BT hardtop with HD suspesion. I have been without a Landy for a while. My parents next door neighbour has a battered old series III 109 hardtop. I think its prob 2.25 petrol, he's going to "get rid" of it soon (nutter). So I am considering giving it a good home. If I do take it on, can I squueze either a recon 200TDi or 300TDi & a R380 gearbox in?? Or would anyone be able to recommend something else. although I'd like to my budget won't stretch to a TD5.. - any advice would be appreciated. thanks. T

20tdi will fit as will g'box (some b/head mods req/d)
Gas a hc v8. Same mpg, scare beemers
