Jet Turbine

ok mate, are you trying to buy the jet turbine? easy, find the guy that does the body shop in my city! then you can buy it from there :D. HOPE THIS HELPS :D

if u wanna get the jet turbine/rockets u need 2, 1st of all, have the "big" tires; as they will make climbimg the cliffs on papaya island much easier; if u have the water skis, all u need 2 do is drive to the northwest side of the island, (on the water,)

U get the jet engine after u help sandro:
1. At papya island jump the first cave.
2. Move onto land
3. Talk to sandro in one of the houses
4. He will tell you to find his wife(a green car).
5. Jump the second cave(the one you past).
6. You will find her wife
7. Go back to sandro.
8. He will give you jet engine

Trust me this works

For jet turbine you need to talk to the guy next to the coconut shop he tel's you to find some 1 she is also in papaya at the river

1.Talk to sandro (he lives in papaya island near obstacle course registration hut).
2.He asks you to find kerori (his wife) (the color of kerori's car was green).
3.go to the cave that towards the portal through cloud hill.
4.if you see many coconut trees, find kerori she was loafing around, REMEMBER HER CAR WAS GREEN.
5. If you found her go back to sandro and he will gave to you the jet turbine
NOTE:if you have the parts shop in "my city" it will add to the part shop, even those other parts you've obtained like tyres,chassis,etc will be added (The Jet turbine was belong to the options section).

You need to help Sandro to find kerori(Sandro lives in papaya island near the obstacle course registration hut). Kerori was stranded in many coconut trees The color of Kerori's car was green then talk to her, after you talk to kerori then go back to sandro and he will gave to you the jet turbine.(it will add to the largest parts shop that found in "my city"(if you talk to the ice cream van just drive the whole road I don't remember where it is). So you can buy 2 more for your teammates.
