Title: Omega engine conversions - bigger diesel?
Post by: Varche on 24 November 2014, 16:09:43
We have covered the V6 mods and possible insertion of a V8, has anyone ever contemplated a bigger diesel engine?

Could it be done? I am not talking 2.5 Dti although that is a step in the right direction.

There are some mighty impressive diesels around now. I drove a 2.0 Bluemotion VW recently. 175BHP? and 60 to the gallon. BMW 3.0 and gearbox?

When I looked into them a few years back, some where getting up to 200bhp with some simple mods and maps, but seeing we never got them in the UK it will stay a Euro thing.  :(

Bmw straight six is a nice, obvious choice as it's a derivative of the 2.5tdi lump :y

The 3.0 cdti lump from the Vectra would be an interesting project, but would require some headscratching to fit a rwd car, although this then raises the possibility of twin turbos 8)

Chevy/Cummins V8 diesel lump has comedy value, but weighs the same as a whole Corsa ::)

Forget modern engines, the ancillary electronics required such as CAN based drive train and instrument ECU's makes it a no go.

what about a merc engine?

what about a merc engine?

There was a modern Merc diesel fitted to a 190E... Anything is possible given a big enough budget.

Mercs are quite modular, making the mechanicals a pretty straightforward swap... putting a 1990 5.6 V8 into a 1981 W123 E class estate, or a 6.0 v12 into a pagoda SL... the real expense comes from making the wiring work and then making it all look factory :y

Most Older(pre '00) Mercs have steering boxes, and most models were sold in Germany and the US with V8 options, so for the most part, the chassis were always designed to take any engine in the range :y

I know of a MK1 Escort Van with a 2004-5 BMW X5 3.0D engine in, so anything is possible.

My New Years project involves a 190E and a W124 straight six... And a manual conversion. :D

Thought the hemmi v8 won this last time round?

Oh I could fit one and get it basically working.

But it wont talk to any other systems and will sit moaning all day long about missing signals unless you then also fitted instrument ECU's, the correct ABS unit, chassis control modules, body control modules etc.

The only alternative is to fit after market ECU which on common rail setups is a git.

The 3.0 cdti lump from the Vectra would be an interesting project, but would require some headscratching to fit a rwd car, although this then raises the possibility of twin turbos 8)

It was available in the preface Vectra C/ Signum half CAN cars so shouldn't be too hard to get working, to make it fit RWD just turn the engine in the same way the V6 petrol  (basic lump) is as used in Omega/ Vectra.

However its not a tuneable engine iirc in preface cars its around 184bhp, facelift its 197bhp (or the other way round) and the few that have tried to tune it have had lots of issues fairly quickly afterwards!

It you want twin turbo then there is the 9-5/ Insiginia 2ltr lump that has twin turbos and 190bhp, which apart from the CAN issues could be a good place to start

But to be honest performance diesel is an oxymoron, you want a powerful, big engined, fast, tunable car, buy a petrol with forced induction :-)

6.79s quarter @ 211mph .. that's a fast diesel ;D

I don't think you need to worry about the CAN to much, you can get a electric box that tells the ecu it's on a test bed so runs happily out of the car in the work shop or omega engine bay ;)

If it weren't for the fact that Mark is right, the Jaguar (peugeot ford) 275ps twin turbo diesel v6 would be a very good match for the omega.  8)

Although handling would be "interesting"  :o
