i just swapped a K24 turbo on my TD, and i LOVE it.. spools nice and low, prolly not as low as a K03/T2 tho, but ive never driven an IDI with one of those turbos to know how it performs.. i do know that i LOVE the way my K24 performs with the wastegate unhooked tho.. they have MAGIC wastegates.. leave them unhooked, and they POP open from exhaust drive pressure at around 25psi.. works nicely actually.. the K24/T3 turbos spool nice, and there good for lots of boost.. 30+psi is easy from a K24 or T3 turbo.. good for making power on the top end..
Now THAT I didn't know about K24 wastegates; is it safe? Does that cause too much spike or is it quite an even spool to max boost? Either way I know what I'll be doing with mine when I get it. 
Heard so many good things about the K24 it should be called the 'Jesus turbo'. 
working wastegates will pop open.. stuck wastegates will blow up the turbo..
and no spike that i can tell.. regulates boost fine..
thanks for the reply i dont realy know what im trying to get out of it at the minute. probably would go for low down power i think.
Hi again
Engine is finaly in. now for the problems.
1 the heater plugs dont work (well the light doesnt come on)
2 more importantly no fuel getting to injectors
is there anything i should be doing wiring wise as the new engine has the pump with the wires hanging out of it
where as the old engine had the manual cold start and all that on it,
everything seems to have just plugged in to the origional looms on the car so i dont know what to do. the pump is moving fuel as you can see it in the clear pipes but not getting to injectors
also in both my manuals the only pump it shows is the old one and says newer ones have self diagnostic something on.
please help
Thanks
Andrew
Are you sure that your glow plug relay and fuse bar are good? Do the wires and plug boss have continuity and low resistance? If so to all of that, then maybe your glow plug lamp is inop, maybe a concern with the PCB on the cluster. EDIT just realized it's a vento, NVM.
AS for the pump, are you getting 12 volts to the fuel shutoff solenoid. If yes the are you sure that it is actuating? Might be a good idea to pull it out and see. Hopefully the pump hasn't got an internal fault. Crack an injector line and see if it's moving fuel out the lines if you haven't done that already.
Mind if we get a shot of the pump so we know what kind of plugs you are referring to? Also wouldn't it just be easier to put your other AAZ pump on this, assuming that you held on to it? I mean it worked correctly and didn't leak, right.
And my name's Andrew too! High fives!
i will have a check with everything today. i was just wondering if there was somthing you had to wire up different with the newer pump. maybe the solenoid was on a diferent wire or what ever,
as for swoping the pumps thats beyond what i would be comfortable doing so would have to get some one else to do it they seem like a bit of a pain to get set up.
i just left the engine complete as it was running fine when i took it out of the golf all i changed was the turbo and inlet manifold.
i willl have a look today and report my findings
thanks
looks like i forgot to report. the engine runs now has a lazy injector on start up but after this long im not complaning, the start problem was cured by smashing off the plastic box from the ip and direct wiring it to a ignition live. started up no smoke what so ever turned up the fuel screw a little still no smoke, i can see this engine needing a good tuning
but i will just be happy driving the thing maybe next year. also if anyone is interested i have more or less every part from a aaz engine sat on a pallet so if any one needs anything give me a shout and i will try and sort something out.
Intercool that puppy, then turn up the boost. The AAZ has lots of room for improvement.
