The 2.5t has a lot more potential to get a lot more power/ torque easier than cheaper than the v6, 370Hp is easily attainable out of the turbo 5-pot, ŁŁŁŁŁŁŁs have to be spent on the v6 to get 300hp
The question is not why bother with the 2.5t, but why bother with the mk3 Mondeo chassis, just get a mk4 Mondeo or mk2 Focus with the 5-pot turbo engine already in it (ST/ RS )

Ł6k gets you a low mileage 2.5 Mk4
I'm all for people coming up with something new, but it's just not a conversion that makes sense.

st220 conversion with a st225 engine
hi there, having read the threads and feedback about this conversion well i'm all for it though yes its going to be a costly conversion though it's only a matter of time before someone else actually does it anyways don't you think, in my opinion the mk3 mondeo shape and design is way better looking car than the mk4 by far???? i currently looking in to prices on a st225 engine and a price on fitting
i'm open to all suggestions and ideas out there, any idea of prices for fitting and is it a straight fit or do alterations need to be done etc....
i await any replies thanks in advance
regards tony

Any further info on this, Im currently contemplating this as st are now relatively cheap and fancy something different just could do with some key info on ecu and loom layouts compatibility before beginning. Did anyone ever do it and do they use same ecu manufacturer and loom layout?

ecu manufacturer and layout is of no consequence if I can splice the loom to take its feeds from the same place I did this with a gti6 engine and loom euc etc I fitted to a 405 was really easy to splice the looms and worked perfectly

I've found that life I needed.. It's HERE!!
I can do the wiring in the mk3, either 2.0 or 3.0 v6 Duratec. The Volvo bassed st is on a differant ecu platform.
Of coarse if you have a cashed 2.5t kicking about I wouldnt mind a play but I suspect the ecu will be over reliant on canbus.

Had a quick look and it appears that even the 2005 st has quite a established can network the binnacle forms part of this and terminates the signal, found this out as it’s a common fault for them not starting causing issues with the canbus! some good youtube videos and some one explains it quite well wish i could pick his brains on em!

Yep and you will need deep pockets for aftermarket as not many will do five pots.
You could do a 2.0 Rs based turbo zetec into the mondeo as they are on the same platform.
I've done them as well.

could do with speaking to a canbus expert so see if it can be fooled or its just uneconomical, its only the donor ecu that will require canbus input hopfuly not the car i.e the mondeo st220.

Unless its a very early Volvo they are mega tied up. Even the throttle body is coded to the ecu.
Bearing in mind wiring up an st220 is childs play for me I couldnt touch a 96 ish Volvo.

its is possible but makes it even more complex as i would prob need a loom and ecu from a volvo suppose i could you this as a donor?

Interestingly the ecu gets the speed signal from the abs ecu along the bus on the six speed due to no sensor in the 6 speed box.

How deep 🤔 I really fancied something different Ive got and st Tdci and I love it just fancied another but petrol with something nice sounding with a bit of poke!

As you say its not just the loom its things like the abs thats mounted on the pump and a lot lot more.

Would it not be easier to get a aftermarket performance ecu and get it running using a base map then get the car mapped on this ecu.

Interesting. Is like with the mk3 mondeo,the ST220 And the 3ltr non ST models. I've heard some people say they have different cams. With these I'm sure it's just the ecu that's been detuned.

anyone done this yet,
im still keen for this, just got my 2.2 st tdci back on the road after 3 years of rest (having run a4 3.0 tdi quattro b7) and forgot how much i love the car just need far more grunt than the 2.2 could ever produce,
i hate the mk4 it looks crap,
the focus also it not my bag and i want something different,
could buy a crap focus st cheap and a 220 its just getting the wiring to work as above, any fresh perspectives?
