Recently had the Tek2.5 courtesy of Dr. Banks.

Next upgrade after suspension seems to be upgrade turbo, somethling like a vf23, TD05 or hybrid from mark at lateral

But what are the risks to my engine on this upgraded turbo ?

Well, you would need a new map which you would have to see me for. Apart from the logistics of that, you will always stress your engine more the higher the power and torque that you produce, as well as your brakes, suspension, clutch, diffs and gearbox.

A bigger turbo producing the same power as a smaller one is generally good for reliability but no-one does that

Reliabilty on Subarus is excellent at the 300 BHP level IMHO, over that opinions vary. Some have been OK at the 350 BHP level, some think it is pushing it.

thanks john,

so on the basis i'm rinning ~270 BHP at a the moment, sounds like the cost of ~£1500 (turbo and remap) would only safely get me an extra 30 BHP

You will have mail in a mo. BTW you also need a knocklink with a sensor if playing with big turbos (about £140 from BR Developments).

The first 50 BHP is easy and cheap, the next 50 BHP is rather more costly, and the next 50 BHP after that is stupidly expensive.

It could well cost under 2/3 of the price you mention though to get to 300 BHP, but agree diminishing returns.
