No you can't just remove the BOV dump tube. That is the most common question asked on DSM boards. Just keep it on :)

The 4G63 is safe to around 400-450hp when properly modified.

Stock TB size on 2Gs is 52mm. You can get a 1g TB which is 60mm as an upgrade.

Stock intake manifold is fine.

Stock fuel rail runs 8's at least. It is fine as well.

Fuel pump rewire kit just runs larger gage wire to the fuel pump from the battery. The larger the wire, the more power can get to the pump. More power, more fuel. Get the idea? :)


Also, don't feel that you HAVE to go with Hahn just because you used to have a 420a. Hahn makes great products, but there are others out there just as good for a lot less money.
