Want to use VN S2 / Vp engine in VN with original auto. Is there any issue with coupling S2/VP engine to S1 auto.

As long as the bell housing is the same and you use the series 2 flexplate you should be fine.
Why the change?? Did the series 1 engine die??

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared. |

Not really. You can still feel how different they pull.
S1s pull much better lower.
I do agree, a lot have been flogged out, but you can get them rebuilt for $600.
We got ours done with everything NEW for $800 |

But none will be as good as the completely new motor.
We thought it was worth it...albeit we had no choice (We snapped the camshaft in the old one), so we rebuilt it...and it's a rocket. |

| Engine and auto rebuilt 30,000km ago. Not particularly happy with the result for either, engine appears noisy/rough, even by S1 standard, and lifter rattle at start-up unless I keep oil changes very regular, auto not the smoothest changer under load and a bit clunky between drive and over-run. I am considering another engine rebuild using a 4.2 stroked C.O.M.E. kit and it appears that it only suits S2. |

unless you are going to be using it for drag racing / daily driver the s2 would be a better choice, as for the rebuild you already had its always better to go some were that has a good rep, and you will only get what you pay 4  |

Just a local workshop that farmed-out the engine & auto, needless to say not used them since.
Back to the original question, so the answer is yes, vp/vr engine is a simple bolt-up to s1 auto provided I have a vp/vr flexi-plate. But do all connectors match & where does heater tap etc fit. VN s1 plumbing is a mightmare and do not want worse trying to fit vp/vr.
Intention is to get more low end grunt to suit limitations of 4 speed auto. Could do high compression heads and cam etc on original engine but would still have s1 roughness and only 3800. Alternative is 4.2 stroker but would need later model block, hence vp/vr and would get smoother engine as bonus. |

Our old neighbour was owed a favour from someone he knows. He rebuilt it for us.
Don't know exactly where or by what company it was rebuilt.
He came over to check what needed to be replaced. Did some measuring and came to the conclusion that we needed an entire new motor (The block had been warped) |

| Another question, believe s2 and later engines/gearbox had a brace between them to reduce noise and extra weigh on the flexiplate/flywheel is this true. |

| no its not true ,, but Im sure they are out ther,,, I can tell you now as long as you have the box and motor , its as simple as pulling one out and bolting then marrying the two together,, there is no tricks no special shims or plates or braces needed.... just a block of beer and some patience,,,, the main thing when doing these motors is you make sure that all the connecting earth's are in good tact and connected properly and the fact that the car will need a engine/ecu reset,,, 1 more thing make sure you have a s2 radiator to fit with the s2 motor other wise you will do your head in trying to get the s1 rad to fit ( I got mine to fit but Im a real persistant prick ) |

in my orig exec I did have a s1 motor and done the conversion to s2 ..... went like a dream!!! in the cal it was a s1 motor (hence being a 88 cal with sunroof) but the penis who put it in copy my motor and fucped up alot of little things that over time created havoc with the engine bay (not the engine) ( work this out b4 you ask me ).... if your askin if I have done this sort of thing I can safely say out of the 23 motor refit/builds I have done (AS A UNTRAINED BACKYARD HACK MECH) have all gone as planned and trust me when I say I am more of a computer nerd than a grease monkey regardless of my trade! But back to your question yes I did leebo  |

| another reason the series 1 feeling like they have more power is that the s2 has a plastic bellmouth inside the manifold if you remove it you will feel an increase in bottom end power holden did this to take some of the so called harshness from the engine and smooth the idle |
