Hello All, new member here. I'm looking for guidance on my 04' Civic EX sedan needing some major repair work. The head gasket is blown (I think) causing 3 misfires and a check engine light. The thermostat fluctuates erratically as well as the heater and A/C. The clutch is also worn out and the transmission probably needs new syncros. I'm evaluating whether to fully rebuild the stock D17A engine with some basic bolt-ons to maintain reliability and fuel economy, or hold out and do a swap of some kind. The 7th gen Civic doesn't seem to be a very popular platform for tuning and swaps. Anyone on here have experience tuning/ rebuilding D17's? The car has about 170k miles on it and the body is in very good shape. I bought the massive Helm factory repair manual recently and I'm not afraid to take on the work myself. Thanks for reading and I appreciate your feedback.
