Yes that crank can be used for diesel but remember that 130PD and 150PD has bigger rod diameter (big end) so you can use only crank and VE / 115PD /100PD with smaller rods.

.As it is the correct reference of Crankshafts?

.This is the correct reference of the pistons?

It is not necessary to change the connecting rods?

Because there is no distributor in Spain?

Thanks

take the long nosed one if you have 038 type engine eg alh/asv/or PD

take short nosed one for older engine, 028 type, AHU/AFN/1Z

the pistons you describe or for gasoline engine wil definatly not work in a tdi.. you need shorter rods and/or custom pistons..

Increasing the stroke by 4.5 mm to 100mm, will only yield 1.986 liters as opposed to the 95.5mm's 1.896 liters.

Looks like you'd get more bang for your buck going with an 82 or 83mm piston. With an 82mm bore and 95.5mm stroke you'd get 2.017 liters. with an 83mm bore, would yield 2.066 liters.

Good luck with your headgasket then*g*

But one question in general: If a stroker crank is used, it is better to use custom pistons than shorter rods, isnt it?

Propably slightly better due to better rod leight/ stroke ratio but definitely more expensive. I`m not sure if there is enough space between wrist pin and piston deck to make 4,5mm shorter pistons with oil cooling channels and omega chamber.

That debate has been going on for decades.

in the worst case you make the piston skirt 2mm shorter, using 144m rods and boring the upper bushing out of center should be doable by a good machinist.. then you only need to invent a bowl

Well doesnt bother me to much anyway...if I want 2.0L i go for a 2.0TDI*g*
I was just curious if its better to leave the rods as long as possible, havent read the posts of the past decades*g*

You always want to have the rods as long as possible. Simplified way down, the connecting rod is the lever on the crankshaft. The longer the lever, the more leverage on the crank, and a proportional increase in torque is generated. The swinging velocities of the rod are also reduced with the longer rod which is always a plus.

Longer rods are better for higher RPM's - the piston spends more time at TDC and BDC for a given RPM, has a faster piston speed at mid stroke, and is easier on rod bolts than with shorter rods. I presume that this will be hard on head gaskets/bolts/rods if you're making alot of bottom end power without changing your injection timing. On the other hand, at higher RPM's you'd need less advance which may be helpful since your combustion time stays relatively fixed, the longer you can stay at TDC, the less advanced the timing needs to be.

Shorter rods are better for low end torque, they spend less time at TDC and BDC, have a slower piston speed at mid stroke and are harder on rod bolts at higher RPM's and would probably require/tolerate more timing advance than longer rods.

Depends on what your goals are - high RPM power - go longer rods and shorter stroke (rod/stroke ratio = higher), low RPM power switch it around.

has anyone built a tdi this way? Is it common? The idea is basically to get more displacement right? Are the gains significant... in terms of all the work this would take?
