Ok this may seem dumb to some people but I can't figure it out!

I've done a search about a 100 times

I'm trying to install my turbo kit and I can NOT figure out the size of the nuts for the 3 studs on each manifold where the crossover or whatever bolts to!

Please help that's all I need then ill erase this thread I'm getting tired of running back and forth to the hardware store.

The threads are a little rusted up so that is probably part off my problem if some one could give me the exact specs for the nuts you'd make my life so much easier thanks!!

I'd have thought it would use a metric fastener, or is it just the engine on these cars that are metric ?

I bought 10x1.5 and they wouldn't work. An 11x1.5 die goes on nice but I couldn't seem to find that size nut anywhere.

I just took mine to the auto parts store and they had it in about 15 seconds flat. Even had the correct knurled nuts.

fyi 3/8-16 and m10 1.5 are SUPER close, once you get 4 turns in is when youll feel or see the difference but most people will just shove it on in

I had no idea. I'd be willing to bet it's metric though.

M10x1.5 is the right size for both car and truck manifolds

Maybe you have the wrong size...or someone has changed them

maybe i should think before i try things! lol my manifolds came coated and while the studs "looked" ok, they needed to have a wire brush taken to them and then the nuts went on, snug the whole way up but they were the correct size....that being M10 x 1.5's.

glad i found this thread and thanks for the input.
