Can anyone tell me the type of turbo on this year of UK car (97 P), as I keep hearing about TD04/5 and don't have a clue which I have!
Also, what is the maximum realistic level of boost this unit can sustain??

It runs a td04.
Its not as capable as the td05 but does pull quicker so in my opinion is better for everyday driving, but I do want a td05 conversion soon....
As for boost levels i'm not to sure about the top but I rum 1.1 bar, I do know of cars running 1.3 bar with this turbo but you will probably need a Front mount i/c to cope with the heat it would generate.
My uk97 was running 1.2 bar and was pushing 270bhp.
Hope that helps.
P.s the td series are hard as nails in terms of reliability.

The TD04 is a smaller turbo than TD05, it will spin up faster but haver a lower absolute throughput.
You will notice this effect higher in the rpm range as the volume of air increases and the TD04 runs out of puff.
As power is directly related to RPM the TD05 can produce more power(if correctly tuned) since it is pushing more air into the engine at the higher rpms.
However at lower rpms you can produce high boost with the TD04 giving you just as good torque as the TD05 with the advantage of the quicker spool up.
Running 18psi on my UK MY97 no problem but drops off above 5000rpm.

Thanks for the replies.
I am currently running 19psi with no problems at all. Was running 20psi on a previous MY97 (which got twocked), which equated to around 300Bhp, while my current beast stands at around 280 ish.
Will have to get more serious (and expensive) to extract much more...

Wrexy, thanks you are indeed correct. After a bit of testing today, it seems to peak at approximately 19psi and hold 18, upto around 5k when it begins to tail off (as described by Rich previously), at which point I tend to change up! My intercooler water spray certainly helps to keep the inlet temps down, but a fmic is probably next on the agenda..
