I need help!! Info on a turbo!!

[MA70-3.0GT]

Not wishing to rain on anyone's bonfire but wouldn't a turbo that size be a bit laggy on a 1.6 motor? I only say this because there's a fair amount of lag even with the exhaust gasses of a 3.0 flowing through so surely an engine just over half the size would produce not much more than half the essential exhaust gas to spin the turbine, at any given RPM?

I'm not saying it won't work because I don't profess to know everything about turbocharging, but my gut feeling is that a large turbo on a small engine would have major lag & possibly even struggle to get up to a speed where it can produce enough boost...
On the other hand it could well be that it will have a lot of lag (that's a given) & then when it does come on song it could be a HUUUUGE amount of fun indeed.

I for one will be interested to hear the outcome of your project & hope you'll post back about it, you certainly would seem to have mucho cohones to be trying this and I hope it goes to plan.

Best of luck, Dan.
