Looking for info (about engine replacement)
I drive an 05 6spd and Im now at 113,000 miles, I dont have much done to her only an aem cai, ignition upgrade, and a cobb tuned ecu. I know I cant turbo charge the engine with the miles it has on it and I love the car so mmuch the thought of replacing her once the engine blows for something new isnt an option. What Im looking for is a vendor or something that sells 4 port series 1 reman engines. I saw a listing on mamart but its for an automatic. Any info would be greatly apreciated.

Thats an easy one once I have the info I get the engine and post the process on here. Ive already pulled the engine on my 8 once already when I needed to replace the clutch. I do all my own work unless its far to involved for me and my equipment. such as pcm updates.

4port vs 6port info that you should be aware of before you waste thousands of dollars on the wrong engine:

4 port or 6 port, which cars had which?: (Updated November 13th 2013)
At first release, there were two different basic engine designs. The 4-port and the 6-port. The difference is essentially that the 6-port has 2 more intake ports than the 4-port. This allows a higher amount of air flow into the engine at high RPM. A 4-port beyond 7,500rpm is being choked by difficulty flowing enough air. The two additional ports in a 6-port provide enough air flow to overcome this problem.Like any other intake flow change, allowing more airflow at higher revs means a shift of airflow optimization away from low revs. The 4-port actually has a few ft/lbs of torque more than the 6-port as a result
Swapping between engines:
Of the 3 designs (4-port Series1, 6-port Series1, 6-port Series2), each design is directly swappable into RX-8s that had that same design. So you can use a 6-port from a 2008 Automatic directly in a 2004 6-speed manual with zero modifications, and vise versa.
The Series1 and Series2 engines can be physically installed in each other's vehicles, however the OMP and electronics differences are considerable. Swapping between Series1 and Series2 will involve replacing every electronics module in the car, even the ones not engine related.
The 4-port and 6-port can likewise be physically installed in each other's vehicles, but there are significant electronic differences that will require replacement or re-coding of at least the ECU, likely additional components. If the 4-port to 6-port swap also includes a change of transmissions then there are additional hardware components that need to be converted as well.
Swapping between any of the different engine designs becomes a long and costly process.
