Advice, buyers guides, 2.0 petrol turbos and many more questions

[The_Wombat]

Just joined today (posted a hi and what I am up to).

In summary, bought a green 2.1 TD estate to save but the underfloor and structure are just too far gone for anyone other than a hardcore enthusiast with a MIG welder for a heart!!

Still want an XM estate, so looking at a silver 2.0 turbo petrol one this week which seems in much much better condition.

Whilst I am browsing the forum, searching for info etc, I wondered if:
- There is a detailed buyers guide anywhere? I am not inexperienced but would like to find all the little nuances to look for as didn't do so well on the green one (but knew it was a risk and it is a complete and working car)
- Is there a right up anywhere on the 2.o petrol turbo engine? I am much less familiar with this unit

Any help would be very appreciated.

The car itself will present in exactly the same way.. under floor cills etc etc..

The tct engine is an iron block dry liner 8v with a turbo on it. The turbos on them are for a petrol unit very tough units. However I've come across siezed units before now.. but at 145bhp and 20 mpg they are just not worth the use..

The young boys used to love to tct engines to go In their 205s or 309s etc but that seems to of tailed off now with multi valve engines. The gearbox if auto will be the same 4hp18 mechical box but different ratios between them .

The other difference is the sound deadening inside and under the bonnet will be different and will be thicker on the diesel .. but really between the diesel and petrol both cars will need the same rigorous checks.
