the lag will depend on any porting you have but it should be a lot, thats wuite a small turbo, i deal for stock ports on an fc.  You can buy a bigger turbo that fits to the stock manifold, has an interal wastagate and takes he stock exhaust.

If you look at something bigger like the gt range, you will need a manifold, external wastegate, down pipe at least

This is the cheapest place I have found for buying a turbo like the GT35R.  http://stores.ebay.co.uk/Himni-Racing

I bought a turbo from them with no problems.  The exchange rate is awesome atm..
