You're not at the sub 14sec bracket yet Stav. And you're already broken 46 gearboxes.

What is it you're trying to do?
Be realistic, what is it you want or need to achieve with your wagon?

I understand it's your daily driven work and family car, right?
If that's the case, I don't think your plans make a lot of sense.

You've done many things the hard way over the years, it took you about 3 years to make over 170rwkw, which took myself and others about 3 months.

You've learnt a lot, as we all have, but you're a stubborn bugger who likes to do things your own sometimes painful way.

You think it's been hard so far, wait until you fit a turbo.....
