X14xe > C16se

[matt_vaughan]

For various reasons I'm after lifting the 14XE out of my *ahem* corsa sport *ahem* and dropping in a 1.6 8V. These include wanting to run bike carbs, and wanting 8V torque back lol for occasional track use.

I know the actual change will be relatively simple but how about running a power steering pump? I'm wanting to get rid of air con anyways, so that's not an issue.

well, as insurance wise, an x16xe will be pretty much the same as a c16se, and an x16xe will fit straight in, and will, with the manifold mod, produce a lot of good useable power, surely you should be looking in that direction......

[matt_vaughan]

I would be, but Im looking for a simpler life. I know 16 valves have more potencial, but they cost more to get there. An 8 valve is slightly lighter iirc (could be wrong there), and potencially much cheaper to tune considering cams, carbs etc.

[mowgli]

the x16 is already 10hp ahead, and with the manifold mod, another 20, then start looking at cams etc... it will always be a better engine.... i've seriously been looking at the x18xe1/z18xe 1800 small block engine... it appears to be a fine engine & quite cheap in a vectra...

the x18xe1/z18xe bolt up to the original nova mounts?

yep

Iiiinteresting :) most on ebay seem to be sold as replacements for new vehicles with broked engines though, so seem to cost a fair whack for a totally bare engine. Worth looking into though... :d

I Think, you can keep the 16v engine mount, You might need to switch to a pas only mount though.

I have to agree with the above though, X16XE.

Ps: The X18XE1/Z18XE is well documented with corsa's, Takes a bit more thinking than a 1.6 but deffo a good engine. Warrens NA 1.8 makes just under 200bhp iirc.

[MK999]

Seen a couple now, only ever on ITB's though, so not sure what the deal is with the standard management. There's a good chance the Z's require some canbus fettling but I doubt the late 90's astra/X18XE1 does. More digging required lol

[AlexW]

Need X18XE1 management/throttle body, Z18XE has Fly-By-Wire.

[MK999]

or a z18xe throttle pedal I assume. Unless, it also requires canbus trickery

edit: it does, so those 10 extra horsies are unavailable without lots of messing about, xe1 would be the one to go for. Must be relatively simple to turbo too as the corsa D vxr is all based on a z/x18 head iirc? Must achieve it's extra displacement through stroke I imagine, being a small block, so there's probably a good chance a 16xe crank fits to make a short stroke low compression engine. Iiiiiinteresting :d

Matt...as you have already have a 16v I would stay that way. I'd love a fast road Nova with a Z18XE on TBs and aftermarket ECU. I think there is a lot of potential there

A Standard X16XE etc isnt Hard to turbo, VXR manifold bolts on etc. You still have oil filter issue on the 1.8. Compression isnt the biggest thing on any of the engines though.

With regards to c16se and pas, you could run a wide multi rib belt bottom pulley, corsa alternator and pas pump as iirc the c16se will mount up on the x14xe mount which holds the pas pump and tensioner then you can just run an early corsa belt without AC. But as many people have been saying, the 1600xe with £500 thrown at it can product a reliable 130bhp where as the 8v will not.
