Mod 1.8 Turbo to 180BHP ?

See the other reply.

Welcome to 1.8T world. I can't remeber the differences between the Golf and TT engines, but a relatively simple ECU upgrade will get you 180+ horsepower for $500US. Check out:

You probably can't make it identical to a 180 hp version without replacing engine parts; I'm not sure about the 150 hp version, but the 170, 180, and 225 hp versions all have different compression ratios, which means a physical difference in the size or shape of the combustion chamber. Bore and stroke are identical, so it would be the cylinder head, the piston crown, or something about the motion of the piston; I don't know which it would be. (Compression ratio does not account for all of the difference in output; they don't all use the same turbocharger.)

As a previous response has suggested, chipping your engine would probably be the best way to achieve an output of approximately 180 hp.
