hi guys if you have read my hello in the newbie section im trying to work out what engine to use in my trike build. Needs to be auto so just rev and go. Ive had plenty of vauxhalls in the past and would like to use a omega v6 engine and autobox if all goes well. So we have got 4 v6's to choose from, 2.5,2.6,3.0,3.2 ok so the 2.6,3.2 are the later engines with different engine management plenty more sensors different heads etc. Ideally i would like to use the 3.2 but the 3.0 would be my second choice or even a 2.5 with g cams in. I would like to use just the engine/gearbox injection system nothing from the steering or braking system, right time for questions ??

1. Do all v6 auto gearbox have its own management ?
2. Does the management have inputs from anything else power steering/abs/airbags/tc etc would there be a way to omit them from   the program?
3. Which engine/autobox would be the easiest to install with management?
4. Would it be easier with stand alone management mega squirt or alike?
5. Which autobox is best ratio for acceleration (top end not an issue as 100 is quick enough on a trike with no helmet  ) ?
6. Does the v6 mate up to older autoboxs carlton/senator eliminating some box management ?
7. Has anyone put a v6 on bike carbs can it be done?

you guys are the guys in the know, any advice or opinions are very much welcomed thanks in advance, alot of information to collect before i start collecting parts, you can see where im coming from there is alot of stuff i would not need but maybe needed for ecu,

Should make for an interesting ride to say the least  .

Someone with better mechanical knowledge of the Omega (etc) is bound to be along soon I would imagine 

If I'm correct with regards to the Omega, both the 4cyl and v6 auto gearboxes have their own ECU management

Whichever engine/autobox you use wouldn't be a weekend job, as I think there's quite a lot of wiring loom for both the engine & autobox.  The 2.6 & 3.2 are Fly-by-wire, so you would need to possibly use the original foot pedal to control the throttle (to be honest I'm not sure if it could be converted to twist throttle like a motorbike, as it's a potentiometer set up from what I gather?)
So you may want to pick the V6 which is cable throttle

Which autobox is best ratio for acceleration (ratio would depend on the axle ratio as that your final drive)
Couldn't tell you myself if the Omega v6's mate up to older auto transmission Carlton/Senator, but as the Omega has ECU control maybe an issue here?

I believe someone on here has played with the Mega-squirt set up, but not sure which engine it was on.  Not impossible about putting bike carbs on a v6 if you have time, experience and money I would imagine, but just how practical or easy it could be done is another question.  You would be better off sticking with the standard set up for everyday use I would have thought?

Good luck with your project

cheers if i go down the 3.2 route could use the 3.0litre heads and management or just use the 3.0l them couple of horses you will probably have spare anyway as it rips your arms off to what ever speed the seat of your pants lets you go before getting brown stains would want to use a twist type throttle with motorbike front end obviously no clutch just park drive reverse and neutral no need for 123   just hang on and go

DBW throttle aside, I don't think the 3.2 would be much of an issue. You might even find the DBW throttle gives you a little more flexibility as it doesn't require a mechanical link, kick down switch, etc.

Also bear in mind that the 3.2 doesn't have EGR, ICV and SAI to worry about / blank off.

I do wonder if the DBW setup will work easily without the abs module, though.

The engine wiring loom goes straight into the ECU in the engine bay, so you should be able to transplant it intact. Autobox ECU wiring will need a little more surgery, though.

.. and the engines are pretty much interchangeable as far as the ECU setups go. Just need a plenum and manifolds with the manual throttle body, EGR and ICV holes to transplant a 3.2. Oh, and cam covers so the plug leads seal. No reason to swap heads at all. Later 2.5/3.0 heads have the threads in to mount coil packs if going that way.

Sounds like a fun project.

Could be interesting fitting the pedal to a trike though!

That's good news, as I'm planning on using a 3.0l and auto in my Standard Flying 12 at some point. When the Avenger's painted and Deb's 1300 has had it's new front panels fitted.

It would take a little bodgery, yes. I'm sure the pot from the pedal sensor could be operated by cable somehow.

Excellent! Should surprise a few folk at the lights.

its a gonna take a bit of thinking but im sure the engine/engine management can be sorted the auto box is the thing could an early box be fitted gsi carlton etc or something else

Carlton, Senator, etc. all used pretty much the same automatic gearbox with electronic control. You might be able to go earlier to get a more basic all-hydraulic box. Depends if you have enough room for the electronics and if it'll behave with a much lighter vehicle. Whilst there's some adjustment with a basic autobox, you don't get that with an electronic one, of course. I reckon it'll be OK, but you'll have to suck it and see to an extent.

If you really want to go to town, ro you really don't get on with the stock ECU, some of the Megasquirt guys were building a mappable automatic gearbox controller. No idea what state it's currently in, though.

Would the Monza/Mk1 Carlton provide a suitable autobox

thats the thing would like to have the angles covered its a hard call v8 tried and tested vaux v6 could be a money pit but a one off
