My brother is going to be installing a TNT F1 wet nitrous kit on his 99' GMC hopefully by next week.

First of all which purge kit do we need? The -4AN or the -6AN? Can't find this info anywhere.

Also, which purge kit do you guys recommend using?

We were thinking of getting the Edelbrock or the NX kit. Are these any good?

We would like to get the TNT purge, but we cant find it listed anywhere. Not even on their site.

What do you guys think?

Thanks in advance.

 

Most kits are going to be the -4 size. Any cheapo silenoid will work so just find the cheapest one and use it.

 

If I can help let me know. We have two quality, low priced purge kits.
