Carbureted LSX forum - Super vic carb on a efi intake help

does anyone know what size expansion plugs fit the injector holes to plug them to run carburator on an efi intake?

I tried 9/16 and were to big. 17/32 was to small. Oriely's said 14mm would not be it but I think they are wrong.

Temporary? If not I would have them welded or try to trade someone. Otherwise, I would bring the intake to a store and figure it out on spot.

plugging them until i decide to go efi. May never happen but if it does its simple enough to pop the plugs out.

Yea.
Bring with you to the store. And try metric and inches.
Theres a old school auto parts by my house that lets me look thru there stuff.
Idk if vatozone or the other regular parts store will allow you figure what you need.
Some of those ppl dont even know the difference between vacuum,fuel and radiator hose.
They may ask you what year and car the intake came off. Lolz!

I was going to use a 14.4mm at first but then decided I'll never have injectors on it so a 3/8NPT tap and a few plugs later I was done.

14 mm did the job, fit perfect. Popped them in and sprayed the intake with clear coat.

any problems with installing the plugs in the intake. do you remember the part number. orielys here cant find a 14mm plug

My brother ordered them through Napa for me. Oriely's was idiots, they told me they dont make metric expansion plugs. No problem installing them though.

I'll check tomorrow if I have some 14mm plugs in the machine shop if you still need. PM me to remind me if you still do.

If anyone wants to trade an injected one for a carb'd intake I have a brand new one thats painted black I would trade.

do you have a ls1 or ls3 intake
