Astra Coupe verde green engine rebuild

[danny s-p]

hi so on April the 1st i got my verde green astra coupe 2 months after owning it i had a miss fire code flash up. took another 2 months to fined out the head had cracked an was leaking water in to pot 4 after changing sensors plugs and then finally came to try a new coil pack to fined the plug holes covered in coolant. so off came the head and on went a new one. the problem had been fixed yey. but a big but the water had damaged the bottom end so off to zzp to import all the new gm parts.as it about £150 cheaper to import the engine rebuild parts than it is to buy them in the uk. in the next week i will be striping my new 2.2 with only 45.000 on it why waiting for the parts from zzp arrive there in uk customs as we speak. here some pics

[Sjdickso]

Great progress but I was under the impression the weapon R wouldn't fit the Astra?

Great progress but I was under the impression the weapon R wouldn't fit the Astra?

it does once you remove the ac pipes and move the fuel lines from what ive been told

 

[danny s-p]
