thank you everyone,i will do some calling today and see i i can get some mre answer from the previous owner.

Hi,after some phone calles and sreaching yes it has been tuned but no one can tell me whats actually been done as they all keep no records,so still searching for info,pulling up the carpet and foot plate and checking to see what ecu is there and if anyone has written anything on the outside......the search goes on.....

Ring allstar garage, maximum motor sport and Race Torque.. its very likely your car has been tuned by one of them

using the search button!lol

Can anyone confirm if a tdo5h off an ej20 will bolt up to an ej25?

They go OK, but they only have a 16G sized rear housing I think. A 18G is where the party starts
I had a TD05 18G on my old WRX (2004 EJ20), made just over 280WHP @ 19PSI

EDIT: If you have a 2.5L motor the 16G would be a waste.

Pointless. I thought cash wasn't an issue?

If it isn't a factor then Twin-Scroll 2.5L would be leathal!

2.5L + Twin Scroll + TD06 XXG = Profit

At the moment im just trying to test different set ups to see what i like from the info i found the td05h has a flow rate of 505 compared to my tdo4 at 360. im looking for a car with good street drivablity not just large numbers, so not wanting to go to big to keep lag down

Yes it will bolt up no problems. As said 18G housing would be a good option.
