I could have swore that I heard once that you can put the GSL-SE Primaries in as Secondaries in a 2nd gen for more cc's. Anyone heard this as well.

 

Yes, this is correct, these are 680cc´s even though 720cc is an even better upgrade.

 

Well I am having all of the intake ported this week and wanted some more fuel to go with that air. I am not porting this engine I am going to port the next after this blows.

 

Is your car N/A or TII? If N/A, use a pair of TII 550's in the secondaries and you will save cash since they are cheaper. If you have a TII, the 680's would work fine. You may need resistors depending on what year your car is, and you will need a S-AFC or equal to control them so you don't run too rich and loose HP.
