Ordering a big list, what else do i need?
1. Meziere natural ls1 waterpump
2. waterpump gaskets (2) for 99+ ls1
3. fast 90mm intake
4. ls2 tb w/ harness
5. fuel rail kit/w installation.
Do I need new regular GM intake manifold gaskets? Can I reuse my stock thermostat and thermostat housing? Or do I need the expensive meziere one? Thanks!
