| 1.8 Small block Corsa B
1.8 From a 2001 Vectra B, this was a STUPIDLY easy conversion. I can't believe it isnt a popular one? 
Work so far:
2.25" Straight through system
Adjustable FPR
EGR Removed
Induction Kit (Or george valve as I like to call it  )
280mm Discs + V6 calipers
Coil overs
Front + Rear braces
Polybushes
Braided brake lines
At present she goes very well, its on par with my mates Redtopped GSi.. I plan to get some lairy cams, build a plenum and I've got a better manifold.. These engines are good for 170bhp without too much of a headache.

Its not a very common conversion because unless your going for tb's etc etc, its not really worthwhile fitting over a 1600 16v, which are more common to buy and get parts for. (Std power difference is only like 10-12hp) | |

Its on par with a local XE'd corsa and pushed a TypeR up the road... So what more can I say. | |

I think the characteristics of the engine better suite the Corsa too.. Revy, light weight and the variable inlet gives a nice ballanced power/torque delivery.. | |

The Z18XE has 130 BHP, X18XE1 115BHP.
The XE1 was used from about 99 to 2001, then the Z18 from 2001.
Z18 has electronic throttle so a little bit more work.
They a longer stroke X16XELs so will fit wherever a 1.4 or 1.6 XE does.
There are a range of engine covers you can get too, The one in the pic is a Z18XE one, the X18 one has the rear section in black textured finish.
The Corsa C one is all black textured and a lot smaller profile.
The Vectra C is a massive silver boxy one.

The Vectra C is a massive silver boxy one. | I thought that the Z18XE one was plastic (and a bit lighter...), is this true?
How about electrics? Were there any problems or just the usual X16XE-out-of-the-box conversion?
I am thinking to follow the X18XE1 route too, but can't decide... | |

whats does the x18 needs to get 130bhps?
if price is slightly over a x16xe i would go for it.. if its more than 600 poundish i would go 20xe.. | |

but the down side is that those engines are overpriced.. they are in most cases recent. | |

a safe 200bhp+ is possible on standard internals.. I was at TOTD a month ago and a guy with a corsa C 1.8 turbo (Z18XE) run 204bhp.. | |
