The DB2 pump will fit fine.

You may run into a slight issue with the injector lines.

The old 6.2 engines used a slightly different angle on the injectors and the fuel lines area tad different length.

If you use a set of lines from a 92-93 6.5 that had the DB2 pump, your good to go.

The later 6.2's used the fine thread injectors, just be sure yours are the shorter ones.

Other than that, you can use all your 6.2 accessories.

If the engine comes with a water pump, be aware, the 6.5 water pumps are designed to be used with the serp belt and turn opposite direction from the 6.2 v belt drive pumps

The intake and all that stuff will bolt right on. Same with the exhaust manifolds.
Water crossover will fit too.

Be aware that the later 6.5 stuff (AMG) have metric bellhousing bolts.
The GM part number on the bolts is 15724226 get 6 or 7 of them (a spare is nice) These have a stud top but can be used in all six locations.

These are very close to the 3/8-16 bolts that were used on the earlier engines and will fit the tranny holes fine.

The bolts in the side of the block where the motor mounts bolt on are also metric on the new blocks. Those you can likely get locally.

Your starter and the "tail hook" will all fit.

The new blocks have a couple extra oil pressure taps. One up front on the RH side for the turbo and one in the valley under the intake and one in the rear of the block thatis in the normal location for the Oil pressure switch.

The oil cooler ports are 1/2" pipe thread instead of the 3/8" pipe thread.

You can use the little 3/8 to 1/2 "Thin" adapters to allow your fittings to work. Or, if you have a remote cooler thats plumbed in with braided hose and JIC fitings just use the fittings with the 1/2' pipe thread.

Your vacuum pump/oil pump drive will work fine from the old engine.

Depending, the RH valve cover may have a CDR port.

You can just plug it and use yor original Oil filler tube and CDR from the old engine. (Breather)

The air filter will work too.


Pretty much a bolt in part for part swap (Almost)

The issues with the injector lines is going to be the same with the 599 engine too.

Now power will be good, the mileage may fall of a little bit due to the AMG engines having larger precup/ports

With a good set of C injectors and the IP set up well, it should do fine for ya.

Good luck and if we can add anything else, just let us know
