I have a D15b2 head which i swaped on a si intake mani.. Which intake gasket would i use? should i get a intake gasket thats for the block or the intake mani? any help? thanks

 

the d15b2 intake mani has a circle for the coolant passage and the other intake has like a square type opening for the passage.. should i get the one for the intake? It all lines up, so should that one work out?

 

It shouldn't really matter if both manifolds share the same mounting flange/bolt pattern. I would just get whichever gasket is cheaper if there's any price difference. Otherwise, get the one with the larger coolant bypass opening if you're concerned about it, but keep in mind that the coolant passage on the head is still going to be square shaped so it doesn't really make a difference. You can also just enlarge the opening on the gasket if you want to.

 

thank you.. i made a big mistake when i had the motor out i tried using a exhaust gasket and i just cut the edge to clear the bolt and fit and now after i put the motor in it leaks bad! i dont know what i was thinking but now i have to change it.. but thanks alot

 

thanks, i guess it didnt really matter after all.. and there was like a 4.00 difference but thanks alot, its all done now..
