Iv had one of these, a 220 turbo, the oil return pipe from the turbo used to leak and everytime i booted it would leave oil smoke inside and behind, the only prob i had with it was the chassis twisted under the torque of the engine and ripped it apart from the bulk head to the end of the chassis leg, had it welded up, i loved it tho, i used to wind so many cars up with it when out and about as it was 200+bhp, then i got myself a 420gsi turbo, a light blue colour one that had been heavily modded and been on ebay a hundred times, i shouldnt of bought it as it caused no end of trouble, but i learnt from my mistakes
