i was wondering if anyone can tell me what size the bolts are that go into the head that hold the intake manifold on and the ones that hold the upper to the lower... i went to nissan but they want a billion dollars

if you have a bolt that is the same size/pitch thread you can find out for yourself. just get a rod to find out the length of the bolt, and then take a bolt w/the same threads to a specialty bolt shop and they should be able to figure out what you need.

look around your engine bay for a similar size bolt, it does not have to be the right length just the pitch size. it might be a 1.25m pitch size and maybe 12mm, but im not sure. i know the egr bolts are 12mm and mayb 2.5" long. mayb that might be the same size, try taking the closest/easiest bolt off of the egr and see if it threads into the manifold.
