You can put an AAZ pump on the ALH engine and get it to run but it will run at a fraction of the stock performance. Basically, it will be a slug. The pump needs to be modified extensively to get an mtdi that runs at stock levels.

i surgest you do a gov mod to start with as the disco pump only revs to like 4.5kon a 1Z the woodruff key needs to piont towards the cam at TDC, on a 1Z the pump sits almost upright, ALH its almost on its side, so i would think the key should be pointing at the sky, then use a depth gauge to get it spot on, cant remember what we timed it to now, think it was half way detween stock disco timing and stock 1Z timing, have a play you will find a sweet spot, use the biggest nozzles you can get the pump is gona give you more than enough fuel, just need big enough injectors to get it all outhope that helps, sorry i cant be more exact, i didnt write anything down and cant remember it was ages ago, if its anywhere will be in one of my threads, might be worth a lookcheers, richits actualy a 300 tdi pump that we use, we just call it a disco pumpwe ran ours with AAZ cam and T3 turbo, ran about 240bhp, was unbelievably fast, eventualy blew it up beeting a skylinedropped a valve as it reved to about 6k and had too much lift that it was touching pistons. we are now rebuilding it with PD bottom end and ALH head. its pretty amazing, we are hoping to get 300bhp reliably, will see how it goesgood luckthink it was 240 nozzles, AAZ cam, garrett T3 off an early 1.6 TD with 2.5"down pipe and no exhaust, disco pump wasnt even maxed out, if the nozzles and turbo wer bigger we could of achieved moreur little turbo will hold you back, ull have no lag but wont flow much air and your EGTs will be through the roof, if i wer you id go bigger turbo and down pipe or ur pissing in the wind, get a little holset turbo, that should kick *** and last forever. this link might help for sum stuffhttp://www.volkswaparts.com/rich
thinking giles wants 1500ish to build m pumps with parts you supply...
