Hi,
welcome here.
do you have someone who can build a pump?
Turbo: do you want to buy used or new?
With a good pump even the stock turbo off a 603a will do the job...
I personally don't like the turbo lag so my choice is a slightly bigger one.
I have no experience with Holset but what you can read here a HX35 should be o.k.
elements: the bigger the better and no compromise on quality.
At least 7.5mm.
IC: water/air will keep the plumbing small. Preferably something across the valve cover. I still have not found MY best solution but it might end up in n/a intake manifold modified to connect a flat IC. Then a separate water circuit with radiator (maybe A/C condenser), expansion tank and pump.
Where in Croatia are you located?

Hi....I am from Zagreb,capital citiy of Croatia...
Unfortunately I dnot know someone who could rebuild a pump...But I am in seeking of...
Turbo doesnt really matter is it new or used(always can be repaired)...Getting one is the problem, from a truck maybe, or some other cars? 1.9 TDI fans are satisfied whit 3.0 Audi Turbo or from e39 530D Turbo...
I also share your opinion...Dont like the lag too...
Further more...On the elements which are real mystery for me...Where to buy them? how much they cost and how to fine tweak the pump when it all comes in place?
Sry for being a noob but hey we all need help sometimes...

Hi,
if you can control a BMW turbo (VTG/VNT) then the mentioned GT25.. is a good choice. I have 2 of them, rebuilt, but too stupid to control the boost.
My next option is a BorgWarner off a V12 600 biturbo (wastegate).
But still playing with my stock turbo and other settings.
You're right elements is a real mystery

RE: om602 Turbo tuning - kova - 05-28-2012
Ok! Change of plans! Not going for 300hp! Because lack of bigger elements I will be satisfied with 6mm...
Well...I did some research..whit 6mm and whit proper pump tune it can be expected more than 200whp of om602...
Next thing that is bothering me is the turbo? What turbo would do the trick? Dont want too much of a lag...T3/T4 or others? What dims? please help!
