Larry I have some suggestions for you before you throw the motor in that car that will make your life much much easier.

I'd buy an S14 SR20 waterneck, a turbo gasket set (get the S15 manifold gasket), some braided turbo lines (you'll have to tell them you have a red top with T25 but you have a S14 waterneck), go ahead and do your front and rear main seals, check out all of your sensors/just replace (TPS, IACV, ACC, O2, CTS) them because it is easy as shit to work on the motor outside of the car.

I'd order everything through: thenismoshop.com - the prices there are great and they usually have the stuff I listed in stock (minus the turbo lines).
