A friend of mine is pretty turbo savvy. He has played around with a lot of them on 4wds.
He is convinced that this turbo is too way too big and a waste of time. He thinks I'd be better off using something off say a Charade turbo or TX3 laser. He simply said a old 1.4 wont have enough exhaust gas to drive a turbo off a modern 2L. Logical argument...

I've been thinking about how to reply to this all day.
Without wishing to insult your friend even considering a turbo off a Charade shows to me that he really doesn't quite grasp just how much air/ fuel these little motors actually flow.
As I said before I actually ended up using the biggest T2 available off an 1800SSS Bluebird and that was still too small. That started spooling seriously at about 2800 and would rev through to 7500 no problems.
Considering the Japs are renowned for putting too smaller turbos on cars I honestly think that you should have a leap of faith and just try what you've got.
Remember too that your application is vastly different from some-one with a 4wd, so what if it boosts a little late. The thrust back in the seat as you watch the speedo climb and grab gears some would say is better than sex and you'll more than pick it up in the top end!
Interesting what Sikyne is saying about the exhaust manifold. My experience using a 'J' has been really good but if anyone would know Simon is the man.
8lbs boost, sensible spark and correctly fueled and you will have a great little powerplant. Go make it happen and remember plenty of pics so we can follow your journey.

Cheers
