Fits but....

Dorman® 674-895 - Cast Iron Natural Exhaust Manifold

Fit good. Flashing in all ports and the turbo side port was very bad and just crumbled apart. Would have easily broke off and went through the turbo. Had to file and chisel a lot. Ports on block side of manifold were a lot small the the OEM manifold. No gasket for turbo and the studs to short for turbo mount. I had to use the old ones. It did fit and I was able to make it. I would not recommend based on the issues I had. Better studs, better quality control and make the ports the same as OEM and this would be a awesome OEM replacement.

Driver Side Manifold

Dorman® 674-587 - Cast Iron Natural Exhaust Manifold

The manifold looks awesome without any defects. Wasn't the easiest of installs but once it was in everything bolted right up just like it should. Looks great and quieted the engine right down. Increased horsepower as well. I would definitely recommend this to anyone.
