Got a mk2 astra 1.3 astra and have been offered a 2.0 8v cavalier. Thinking of swapping the engine into my astra. How difficult is this? Will the engine fit straight in? Wiring loom etc? Also will i have all the parts for the conversion if i buy the cavalier whole or will i have to still get bits off a gte.
All the bits are there, the looms weren;t compatible when we put the 2.0 8V in our 1.6 16V but the job wasn't hard...... have a search, the thread might still be on here (I'll do the same and post the link if I find it)...
If not, there's people on here who are s.hit hot at helping with this stuff (people who I'm not sure I thanked for their online assistance when we done the job).
If the engine is complete with all the ancillaries, its not difficult, it will fit straight in. You will need to use the engine mounts from the astra (the cav ones will simply unbolt)
You will need to use a complete loom and ECU from an Astra GTE, its a lot easier than trying to modify your one or modify the cav one. You can use the box/clutch/driveshafts from the cav....I left these all intact when I dropped the engine in (I put it in sideways )
You will need a fuel pump from the cav or a GTE and run a trigger from the loom, not a hard job. If i remember rightly, the airbox from the cav doesnt fit very well in the Astra so bolt on a K&N to save you the hassle. If you havnt already, you might want to consider uprating the brakes. I would sugest taking a complete system from a GTE 16V so you have disks all round.
Me and a mate, who aren't exactly technical, did the swap in a few hours.
Loads of people are going to reply to this post saying you should save for a 16V. But the 8V is a good strong engine and not slow by any means.
As I say, I am not what I would call technically minded, but if you have any probs then post it on here and someone will help you out, so go for it!
