Its a better turbo and you'll see no more than 360bhp with that spec with similar spool. Go for the td05/20g which will get you 375bhp but make sure you get a 3" outlet on the compessor side or it will surge! Blouch turbo in the states are good to deal with just factor in import charges if you buy from them.

I had a td05/20g fitted to a jabba mani on my 4wd tt,clearance was tight due to transfer box but should be ok on yours. Its 3" on the compressor cover outlet you need which the inlet hose attaches to:)

550 injectors,running 1.9 bar peak iirc on the 20g and it made 375bhp on a 7cm housing and 400bhp on a 8cm housing.18g will get you 365bhp max!spool is actually good on a 1.8,full boost by mid 4's. Speak to owen developments also as they sell alot of the tdo range:)
