Felicia sounds like a great idea.

I would think if you fancied a really cheap scarey car a Citroen AX or BX could be an excellent Q car as they are made of plastic so weigh nothing. You can put a huge engine in the BX as even the 2.0's and 1.9XUDT had bags of room around them, but then you have the suspension and pump to run.

If you want to stay VAG i really thing the felicia would be quite cool, but a 1.8T scirocco would scare the **** out of most other drivers . That plus I think it really looks the part too

AX's are tiny and the engine bay's tiny-er. It's certainly possible to turbo them but I think they work better with more controllable power. Though discussions about MINI s/cs ended with the s/cs are too big.

Thinking of a bigger engine bay, Scirocco, Corrado, Honda Civic... Tighter engine bay... Mk1/2 Toyota MR2... Erm.. 1.8T Subaru Justy... etc.

i'm not really thinking turbo at the moment, i dont like them really! especially not on modified cars! in realtion to naturally aspirated cars there's two distinct schools of thought on this.....

1.) you do a all-out throttle bodied tarmac-tearer from a small (1600cc?) engine.

2.) you do stealthy, with plenty of power(2000cc+)
