I think that turbo is going to be way to big for the 5vz if you are trying to get the least amount of lag as possible. if your looking to spool around 2000 rpm than that turbo probably wont. it spools before 1000 in the diesel because the engine is twice the size pumping a lot more cfm's. The turbo we put on clownmeats is the same size as his 1.6 liter crx. Thats why it spools at 2200 with minimal load and before that in 4Lo. Im guessing you wont see boost till about 3500 maybe. but that might be what you are looking for. Look for this book its awesome and it will help you understand more about turbo's.

This is not a simple build like people may think looking at clownmeats thread. me and him have both built turboed cars and are pretty knowledgable (not bragging just telling the truth). justdont want you getting too far into the prodject and it being a little too much. But me and clownmeat are here if you need any advice.
