Story. Got a Civic Si the had a shitty motor with a good tranny. Now transfering tranny over to new good motor. New motor came with only exhaust manifold on it. Here's my list for needed parts to complete the swap.
-Valve cover gasket.
-Intake manifold gasket.
-Exhaust gasket.
-New water pump.
-New timing belt.
-Oil pan gasket.
-OEM clutch.
?-Shouldn't the oil pump be ok-? New motor has 113k on it.

Anything else?

 

i say buy all the gaskets at the local parts store.. for the timing belt and water pump go to honda. as far as clutch, if u plan on "racing" around... get a act street/strip clutch...or some like product. i loved mine.

good luck

 

The car is going to be STS trim so I need an OEM clutch or equivalent.

 

check your motor mount bushings...
