front mount intercooler
#3
Lag as in poorer dynamics or throttle response? Lag as in increased delay for building measured boost? Lag as in higher RPM required to reach a good level of boost?
What frontmount?
What turbo?
What exhaust?
What ecu mods if any?

Well, yes that's lag, but there are a few things you need to sort out first.
1. Are you seeing a delay in registerig say 1 bar of boost on the gauge.
2. You do have a boost gauge right? What boost does it actually reach?
3. Is it a saloon or a wagon? The early WRX wagon has a td04 turbo which is tiny in flow terms, especially compared to the TD05 found on the WRX saloon and all pre-97 UK cars.
4. The turbo is quite laggy anyway, in part because of the bend in the intake just prior to the turbo.
It's entirely likely that there will be some increase in lag. Some more info would help, like boost being reached, what RPM, what gear you're in, whether you have just changed gear or are coming back on the throttle still in the same gear etc.
