Right this has been mentionned to me several times as an alternative to fitting a turbo which will only kill the engine. Does anyone know where i can get one from or if one off another car will fit and what i need to make this work properly, pipes etc if i removed it from another car, if there is one that fits.

short answer ur lookin at thousands to get this to work...and not one or two either a LOT more !!

been worked out on here as a conservative estimate ur talkin upwards of 6k bud

As said above, to get the best from a supercharger you need to be spending £££'s!

You need a supercharger matched to your engine. If its too big it won't work properly, and if its too small, it will max out too early and not provide the correct power/air flow.

A conservative estimate would be to allow 1.5k for management and mapping, plus 1.5-2k for a new supercharger like a Vortex. Then dependant on how much power you really want, you need to consider engine mods, like cams, and more serious work like under piston oil spray jets, and possibly a change to compression if you want big power. Thats not mentioning strengthening of internals.

Then you need to consider whether your suspension, and especially your brakes and gearbox (clutch) can handle the power increases. Your clutch will need serious uprating, and you'll be silly not to consider a torque biasing limited slip diff to help actually put all this power down on the tarmac.

Yes you can do it on the cheap, but most Vectra engines are getting on now, and they won't last 5 mins if you strap a supercharger to it and then use it hard! Plenty of people have gone this route and killed their engines.

Its precisely this cost thats made me decide to not even bother with my plans for a Z32SE with a supercharger. I'm going to use a VXR lump instead; everything is in place then, it just needs electrics (easier with standalone management) and mounts, and some custom fabrication.

i was gonna do my omega.... 3-6k depending on what you go for

i was gonna supercharge a 3.2 as well, but when i looked into it i thought oh lord no, and bought an evo 6 instead.

so its a vxr engine then!!!! now to find a vectra vxr..............anyone know the exact specs on them? power out put etc and whether they will fit in?

What year is your Vec? Whats the current engine?

Its not just as simple as throwing in a Vectra VXR engine. You could fairly easily fit a Z20 series LET engine though.

The 2.8 turbo is a different story.

Then your best bet is of the two options, none of which are easy:

1. You fit a C20LET (Calibra/Cav Turbo engine). Among loads of other things you will be wanting an F28 6spd gearbox, with a 2wd blanking kit, possibly the X20XEV loom to splice into, and different engine mountings. Its possible you can use your X25XE loom, but unlikely! You also need the C20LET engine loom, electrical sensors, and ECU etc. You then need an X20XEV dash, and I'm not even sure how its wired up as I've never done it.
2. You fit a Z20LET (new gen 2.0 turbo used in Astra/Vectra/VX220 etc). This is mental work. You need the full drive by wire setup, the wiring loom, accelerator pedal sensors, engine loom etc. You then also need an F23 or F40 gearbox. Then you can wire the LET into the existing loom, utulising the ECU for that engine. Again mega work.
3. Fit a X25XE or Y/Z32SE engine, which is far less work. You can reuse everything already in place, and your just stripping down the engines sump only if its from an Omega and thus has a RWD sump pan orientation among other things. You reuse your old gearbox (though a new clutch is recommended), and the engine electrics, and all sensors and ancillaries are from the donor X25XE engine.

Unless its a spare car, and you have serious patience, not to mention very good electrical diagram reading skills and the ability to resolve technical problems your never going to achieve it. Changing the engine alone is enough work for even moderately skilled mechanics. I've even seen qualified mechanics struggle with the work involved in my time in the trade.

Unless you can buy everything off the shelf you are the one thats going to make it work. Its not as simple as just fitting something in the engine bay.. wiring is a sodding nightmare for Z20LETs..

I remember seeing a picture a member took on VVOC years ago of another members Z22SE powered Vectra being Z20LET converted... Half of the loom was exposed in the engine bay, and it looked a right mess. The end result was impressive, mainly because the person who did the job could understand, but most crucially could read both looms and thus could splice the right wires in the right place. Top respect to that guy, he knows his stuff!

I wish I'd saved the picture, because even but the most diehard would very quickly change their mind.

Without trying to offend you, your best bet is to just either fit the X30XE, or the Y/Z32SE engines. These are a near direct replacement of your engine, and electrics arent really an issue.

I've been messing with cars for years, I know a little bit about Vauxhall's (esp Vectras), and I'm fortunate enough to be very qualified as a mechanic, but even with my experience the task of fitting an engine thats not meant to be is a puzzle that takes time, patience and the occasional mistake to achieve. Its not easy, and you should be under no illusions of this fact.

I'm not trying to put you off, but you do need to be realistic.

All i am going to say on this is good luck and see you £4000 later after all the problems along the way for a car that still be worth £2k max





















Sorry vodka night lol
