ive just managed to get hold of a tigra 1600 ecotec to fit in my nova. does anyone know if i can use that manifold on my car, and do i need anything apart from the loom to get it started cos i heard sum1 that these engines have got some sort of immobiliser on them.
Did you not find out if it was immobilised before you brought it? maybe should have asked that if you knew about it.
Basically some of them require that the original key be used, or strapped to the key reader in the loom so that the engine can be immobilised. If you don't have a key, the only way you can get a key made is to have the original cars chassis number, and then vaux can get you a key. Theres no get around for that immobiliser that I know of.
Anyway, the manifold will have to be modified a bit to fit a std nova back system. I don't know of anyone who sells a manifold ready modified. Just Novas might, as they do this conversion all the time.
You'll have to find out what year the immobilised ECU was started to be used, I don't know what it is I'm afraid.
Part of the loom should contain a loop or a piece that sits in the steering column - tape the key to it - this will bypass the ECU immobiliser all the time. Alternatively get the ignition barrel from the donor car and use that key and you have instant extra security.
Oh, and whatever you do, dont try and start the engine without the key or immobiliser circuit present! It will then immobilise and I think it is very hard to unblock. You will need the security code for sure then.......
