Is there any difference between the Import EFI "All" kit and a domestic one?

I know a guy selling a kit that was barely used with a heater and need to know if it will work OK on a Fbody.

AND Is it possible to use that as a base for a MAF kit and how much to upgrade?

 

The only difference in the kit is that the import has a fuel T and clamps you will not use.You will need to purchase some jets..

Yes you can upgrade to a maff kit.The maff upgrade is around 339.00.

He said he has all the jets. Are they different between import / domestic? I guess he has all the way up to 150.

Do I need something different to get fuel off the rail (test port)?

 

If he has an import kit, then the jetting stops at 75hp. You would need more jets, and to convert to a maf kit, you would need the NX109 MAF conversion, comes with all the jets needed, MAF ends, and the correct hoses.
