Difference in 603 Injection pump Non-turbo and Turbo?

[gw-long]

Hi,

In my GW300 460 1981 I am replacing a 617 non-turbo with a 606 non-turbo and automatic gearbox. This will give me 136 HP.

But I might also be able to purchase a early 606 Turbo Diesel engine comming from an AMG. The engine is not in a car and the diesel pump is non-original and mechanical. Seems like the part number on the diesel pump indicates that it comes from a non-diesel 603 engine. It has numbers PES 6M 320 RS 156, 0 400 076 994, 603 070 01 01 ER 0007.

Typical part number taken on a friends 603 with turbo version is Bosch 0 400 076 961, MB 603 070 02 01
and also codes like PES 6M 55C320 RS157 -1

Similar for the non-turbo 606 engine I got:
0 400 076 954, 606 070 03 01 ER 0044 , PES 6M 55C 320 RS 203

Understand that the turbo version might be got some pressure control to avoid black smoke. Also that there is different version for manual and automatic cars.
Does anyone know the difference on the 603 injection pumps on the non-turbo and turbo?
Is it mechanical parts inside or on the outside that can be replaced, or only adjustment\set-up?

Does anyone have an overview and know the meaning of the C and RS codes?

Appreciate any input.

best regards

The 606 IP is an electronic IP , the 603 turbo or N/A is an almost non electronic IP ( only very little Eletronic control).

If you are trying to use a 606 in your G you will need the 603 pump , turbo on a turbo engine , non turbo on a N/A one . You can use a 603 turbo on a non turbo engine , with turbo pressure conection disconnected.The non turbo 603 IP (sedan ) has altitude compensation part 131 on pic (A0000704453) , thats not stock to G 603 IP.

603ips for sedans pns A 603 070 38 01 (mechanic tranns) A 603 070 26 01 ( auto trans)

Hi Bocaina,
Thanks a lot for your reply.

Baes on your answer it seems like I need to find a turbo 603 injection pump for the 606 turbo engine. I can not use the the 603 non turbo injecion pump or modify it.


Youdid include an image of the 603 non turbo ip and also the 606 ip. Do you also have one of the 603 turbo ip?

best regards

If you have a turbo engine you will need an IP that increases injection at the same time of turbo pressure grow. I cant answer your question about to modify a pump, , really dont know. Why not use a pump from a w124 turbo sedam ?
