V6 Crankshaft Info

[Rusty-Tim]

So another kind of related question. I have just blown up engine bigtime in VN series 1 manual. I have a spare series 1 auto. Is it possible to just put the manual crank and therefore flywheel etc in the spare auto engine? Do they run the same size big ends and crank journals, front seals and rear seals etc??

The added dowel pins are what GMH did to the crank & flywheels of the ecotec V6 after the VS manual model (VT,VX,VY).

The crank/flywheel dowels were also fitted to a series 2 VS manual crank. Well, atleast they were in my factory manual anyway

Yes your correct. I should have said after the VS T5 model. As the Getrag equipped Ecotec engined models all have the dowels in crank.

I'm looking at doing a VS SII Ecotec auto-manual conversion... everywhere i read... VN this... VN that... Of the little info i can find on VS... If i get a getrag, and get all the bits required... am i right in saying:

the only thing i need to do/alter, to make it fit is get the crank flange drilled and 2 dowels put in (To stop the 8 bolts being sheared off) ?

If i am right in saying this, does the crank flange come off the crank? because if it does, i can take it somewhere to get it done.

Also, what exactly is "mirror balanced"?? I'm having trouble making sence of what it is? and if its needed on a VS SII ecotec? (again... VN this... VN that....)

oh... i know about the different spigot bush, starter motor and flywheel, i know about the manual ecu/loom and auto inhibitor problem, so yeah... im asking PURELY how to "physically" make it fit...

so are the dowels on the flywheel or the crank? if they are supposed to be on the crank....u just bolt up ur flywheel, and mark where the dowels holes are to be drilled with a texta thru the dowel holes on the flywheel.
if the dowels are on the flywheel, use a piece of thick paper or cardboard and spear over dowels in flywheel, mark and drill/cutout bolt holes....transfer to crank, mark and drill.

Will the manual loom from a series 1 vn plug into a 92 vp. have a series 1 vn manual that i want to put into my vp.

Looks like you know these well, i have a VN manual engine with the flywheel its in a complete going order engine. And i have a VR engine auto with a buggered crank run a rod bearing getting a hiding one long hot day at high speed too long, the rest of this engine was sweet. Question will the VN crank fit in the VR block ?
As my son points out the VR had slight improve in HP due to heads or cam etc I would like to fix the VR motor to go into a Pontiac Fiero as was the VN motor before a crash

[immortality]

It depends on which VN engine you have the early cranks aren't compatible because they use a different rear seal arrangement.

[rodgertoilman]

How can i identify the VN early or late and the rear seal style without opening up the motor ??
