smokey startup.....

Can anyone provide some more input on my little dilemma please?

the pumps both have the same pump heads. 9mm. the AAZ pump has a higher lift cam plate tho.

Ah. The mechanic checked the pump numbers in a book which told him that the elements (is this the same as the head) were different sizes, 8mm and 9mm?

Should i put the aaz cam plate on the gtd pump?

the GTD pump should have a 9mm pump head. end of story.

yea, the pump head is the same as the element. but i sure as hell wouldnt call it an element. its a plunger.

the AAZ pump should be 9mm also if its a turbo pump. unless its an eco-1.9

not many people use the AAZ pump for performance build ups. the 1.6 pump is way closer to what you want in stock form. and much easier to modify from my experience.

i wouldnt just go swapping over parts from one pump to the other without knowing exactly what the outcome will be. you might wanna do some research before you tear into them and mess both of them up.

post up the numbers off the sides of the pumps, we can tell you more about them. we know for sure what numbers mean what.

and have you messed with your timing yet? all your symptoms point to retarded timing. setting the timing is alot easier than building a new pump, because you still have to time the new pump right also. timing is SUPER IMPORTANT!!! do you even know if its timed right? thats the first thing i would do before i did anything to the car. timing is easy to set, and it doesnt take much time. rotate the pump towards the engine about one pencil line. with the injector lines loose of course. you never want to attempt to adjust the pump while the injection lines are on it.

Sorry the mechanic is an old guy (70s) so when he says element it may be an old term for that part. I'll try to get the different pump numbers and post them up here to clarify the size of the HEAD!

Please read my post before where i stated that we have adjusted the timing now, and it runs a lot better. My dilemma now is that i need to replace the cambelt, and wanted to know what would be the best pump / combo to use when this work gets done. As i mentioned, the mechanic has put some doubt into my mind as to why i have a 1.6 pump on a 1.9 engine.

I will not be swapping over bits of pumps myself, i would be likely to mess it up, hence why i use a mechanic to help out!

I have done a bit of research but would like to know peoples opinions and ideas of the best pump / or combination of parts for my engine in this particular situation.

Ok, i have the pump number for the GTD pump which is currently fitted to the engine:

0 460 494 267

most people use the TD pump because its so much easier to tune. and its alot better than the AAZ pump in stock form. the LDA pin actually does something in the TD pump. that pump you were talking about in the last post has a 9mm pump head in it. just stock. i would use that pump no matter what if the other one has a 8mm pump head in it.

Ok, thanks for the reply. So the pump with number 0 460 494 267 has a 9mm pump head? That is what is fitted so think i'll use that one. Should i get the AAZ pump camplate fitted to this pump, get the alignment of the cambelt issue sorted and then call it a day?.... for the time being

you COULD throw the AAZ cam plate in there, but i dont know how its going to make your engine run. it needs quite a few other parts along with the cam plate, for it to run as it should.

Ok, well i have both pumps so all parts from both pumps. What i need to know is which bits of each pump are going to be needed to create this hybrid pump, and still have a pump that works properly for my engine

Any more input from you guys would be extremely helpful?

The camplate is matched to the injectors - the AAZ camplate is designed for a 2-stage injector, so if you're going to use it you need to use AAZ injectors with it too.  You may or may not need the pump head and delivery valves too, I'm not sure.

Ah really, grrrr! I've just had refurbed GTD injectors fitted! I've heard of people using GTD injectors / nozzles on a stock AAZ pump setup, so would i have significant problems with keeping the GTD injectors if i decided to try to use the AAZ camplate with the GTD pump?

I just need to get the cambelt sorted as a priority now.

They'll WORK either way, IE your engine will run.  But they really were designed to go together.
