Ok so really had a gut full of the current tb42 in the car. It's developed an oil leak somewhere, found a small puddle of fuel under the car when I moved it out of the garage. The smell of fuel is very strong. I noticed the smell after flicking it over to petrol from LPG for a few minutes.

What do you guys recommend. I've got the choice between 2 turbos o can get my hands on at a good price.
One is a t04z and the other is gt25.
Has anyone turbo'd their carby tb42 and which turbo would you go with?
