My Ride: 2004 ZHP Sedan
You need to consider upgrading your trans to handle the extra power, and also I do not think the DME from the m52tu will run right with the ZHP engine. At minimum you need bigger injectors. Seems like a lot of expense for a 30hp gain. If you are putting down 172hp at the wheels (don't see how that is possible with a 323) then why bother? A stock ZHP only puts about 200hp to the pavement. And with the wrong DME, you won't be able to take full advantage of the 3.0 motor anyways. A $100 set of headers and pullies would probably be about the same.
