You will need the carbs for a start, Inlet manifold, Fpr, Management to run it, and you will see about 170+ bhp

Depends how you source the parts tbh. For a better price figure contact a specialist tuning company like vsport, or jamsport.

you dont need management for carb's...

personally i wouldn't bother with carb's, they are old hat, muhc better with a set of tb's, more tunable, more modern, easier to set up

may cost more, but if you plan to tune the car more, they are defo worth it

You are correct, you don't, but you get better results with spark only management.

For a new setup the cost will be marginly less than a set of throttle bodys, to pay somone to do it all, but the gains will be significantly less than TB's.

Look on www.sbdev.co.uk for thier price lists...

It's not management. It's simply electronic ignition. It's simply more reliable, and you can get a more powerful spark from it.

It is management, Still allows you to plug a computer into it and adjust ignition timing, Something like Omex 200 Series.

ive got carbs fitted to my xe and it is currently sitting at 187 at the fly with only carbs and reprofiled cams so i dont know what tbs give you in terms of bhp but from 150 bhp standard to 187 with only carbs and small profile cams imo is good for the cost

ITSNOT MANAGEMENT ITS SIMPLY A DISTRIBUTOR THAT YOU TURN TO GET THE SPARK CORRECT THERE IS NO OMEX 200 JUST A COIL AND DIZZY AND A MODULE

Think about what you have written there. The engine has 150bhp at the wheels standard, you are quoting an at the fly figure to prove gains and completely forgetting transmission losses.

can you prove that vauxhall quote there figures at the wheel as i assumed along with everyone i know its flywheel figures they state

just to add that the transmission loss was set 15% where as courtney regal or whoever put theres at an unrealistic figure of 25% and when we rolling roaded it we set it at 25% transmission loss and it was over 200 bhp so we put it back to 15% as they use that figure and thats when it gave 187 bhp

No, c20xe 150bhp at the wheels, with carbs will see that kind of power figure, cams and a higher rev limit could see 180. not forgetting that they are old engines and generally make around 145bhp at the wheels.

The quoted 150hp is at the FLY
They usually do around 130 at the wheels.

AvIt-You are using a old distributor, which works ok. You get better driveability results using a propre ignition ecu to control the ignition. Such as a Omex 200
As has been said..

Yes that's a accurate dyno plot of a XE at the wheels.

who says or where idoes it say at the wheels as there is no transmission loss

Dyno dynamics dyno will back calculate for loss or user error, You will always get a accurate figure.

thanks for clearing it mate it is a fly figure as i thought and said
so then the transmission loss makes it around 130 at the wheels
so in answer to the original question standard 20xe 150bhp at fly
with carbs and cams around 187bhp which is what mine is at now until next week as its going back in to the garage for some more mods
