hi guys is there any difference between the tdo5 and the tdo5h, i have only just noticed that on my 1994 sti i have a tdo5h fitted, is this normal for early sti to have this and also what can they take (bhp)

Thanks David

 

People just sometimes miss off the 'h'.

TD05h should be good for anything up to 350bhp.

 

As above^^ its the same turbo, it was the standard turbo on the STi versions 1+2,
