Is it possible to replace a vn s1 v6 engine with an s2 engine or vp without needing to change wiring ecu etc? I ask as the engine in my EH is dead and I need a cheap get me by engine and have seen more s2 engines. |

No worries the only issue you may have is bolt pattern on the crank.
The series 1 auto had a 6 bolt pattern and the manual had an 8 bolt.
I believe they went 8 bolt both auto and manual with the series 2.
In saying that if the replacement engine comes with the Flywheel/flexplate you should not have a drama. |

Has the radiator got a cap or not??
If it does then you may have similar to the series 2 setup but if it does not have a cap and has what Mechnight73 has described then it is series 1 style setup. |

The surge tank is simple to spot Instead of a conventional radiator cap, it has a plastic "header tank" which on a VN is mounted up near the washer bottle. It has a plastic black cap on it, and one 25mm diameter hose running out of the bottom of it. A stock S1 will generally be a pain to keep cool if you don't have this system. A stock S1 can also be identified by the long stainless steel pipe running above the r/h rocker cover to the thermostat at the back of the manifold.
All you have to remember about the S2 cooling system, is that when you fill it up, there is a small bleed valve near the thermostat housing. The system requires you to bleed out the air in the system to fill it properly |

How do I tell if it has the surge tank or not? |

Do you have the surge setup out of the series one in your EH??
If you do not then it should drop straight in if I remember correctly.
ECU is the same, wiring from what I remember is the same.
What tranny did the engines originally have auto or manual??

The vast majority of the changes are on the intake manifold. The S1 has all the "hangovers" from its US GM heritage; surge tank cooling system, and a hastily installed pipe to the back of the engine for the thermostat (Holden were the only manufacturers to use it in a RWD car). So long as you get an S2 intact i.e. with the plumbing and wiring there it should be ok. The only thing I can think of that might be different is the ignition module, but adapting it will be a relatively easy fix. The S2 use a slightly different management chip, but the others will give you more detail |
