You will lose some power through extra transmission losses running 4wd, and also the extra weight will hamper acceleration compared to 2wd at higher speeds - however traction will be massively increased so you can use more of the power more of the time, wet or dry - so off the line (for example) a 4wd car will go like a rat up a drain pipe.

The extra weight is one of the main drawbacks, it is quite noticeable when jacking the car and is on the list of things to try and sort out after the suspension.

I don't really want to go down the stripping out everything but a pair of seats and the dash as I want to keep the car as standard looking as possible so options might be pretty limited and also expensive.

is this conversion still happening? iv got a 20vt going cheap

Nice to read all those "16V are all dead or dying" comments back at the top of the thread.
Have people backed off on this now that CarlT has taken his toys home?

Hey guys. I was searching for info about Fiat Coupe 4x4 conversion and i found this forum sorry for bringing back old thread, but I have some questions... Does Lancia Delta Integrale running gear fits Fiat Coupe? I read that you used Lancia Dedra (Integrale???) parts... And what parts EXACTLY do I need from donor car to do this conversion?
Thanks
Tadas.

Lol I have all the parts sitting, just need to empty the garage of rusty volkswagen and get started!

whatever happened to this?

did you finish the project?

I've a feeling he sold the Dedra a few months back...

A shame this never came to fruition, but some good background info for anyone researching the possibility.

I was going to vote 20v...

id even have a go at this.

An update:

Unfortunately neither the 20VT nor 16VT Coupe-Integrale came to fruition.

Ed (with a little help from me) created the original Coupe-Integrale concept - the Lancia 8vt powered one on here...

However, we did go to the trouble of getting another Dedra Integrale (and drove it all the way back from Germany to the UK) with the intention of creating a 16VT or 20VT coupe Integrale. We took off all the 4x4 Integrale parts we needed for the conversion, then Ed stored them in his shed. The rest of the Dedra went to the recycle centre. I've still got the original Dedra paperwork, as I'm not sure what I'm supposed to do with it - as its German.

So we have the parts (somewhere in one of Ed's sheds). Ed wants to find a 16VT coupe - as the conversion would be very simple with a 16VT and nicely balanced. He really wants to find a 16VT with some good power mods (~300BHP) and perhaps a broken gearbox (so it's cheaper). However, I know deep down he currently doesn't have the time to start/complete this conversion....

Hi everyone, Im from Brazil, and i need help.
I want to turn my fiat coupe 20vt in 4x4. I found in Germany the gearbox and front/center differential of Lancia Delta Integrale 8v.
I can made my Fiat Coupe 4x4 with this parts?
please help me

Does anyone have the rear set up cluttering up their shed?
Id be interested in the parts

Hi, my friend and I are doing a 4x4 conversion on his bravo 20vt and my coupe 20vt.
This is not an easy job. on first view everything fit bolt on (almost), but when you start doing it you see that there is a lot more problems.
we have done the drivetrain fitment and now dealing with oil sump.. that will bi tricky but we have here a man that is making sumps from nothing so his design will be taken.

2 Pauloalberto - delta gearbox and diffs will be ok, but you need front and rear subframes, driveshaft, driveshaft support plate...
I can offer you a complete dedra integrale drivetrain. Everything you need for a swap.
Or even a complete kit for a coupe 20vt. So you dont have to think anything, just bolt on and drive

Cheers, Josip

A project thread on this would be good. Have you any pics?

I will open project thread when Begbie allow me

Appreciate this is an old thread, but very interested in it.

I have an Alfa 155 Q4, which has the same running gear as the Dedra Integrale bolted to the Lancia/Fiat 16valve turbo lump (16v Integrale engine).

having driven many 155s, from 1.8 8v through to 3.0 24v conversion, the Q4 makes an interesting proposition. Although it is heavier, and looses some power through the 4WD system, it is much better balanced due to more weight over the back axle, so the handling really does stand out (as well as the traction). Easy to get the power up as well, and the 4WD system is strong up to a point.

Also interested in how the 4WD system bolts to the 20VT. Not that I would ever strip my 155 (it was Simoni's press car used for parade laps during the 1994 BTCC season), but quite interested in using it as a template for building a 4x4 Coupe!! That would nicely balance the 20VT 155 I will be building next year!!

As Josip says you can use bits from a Delta Integrale but what you really need is a Dedra or Alfa 155 Q4 which are both quite hard to find (and justify breaking!) in the UK.

I can't comment on what you need to bolt it to a 20vt but as I understand it at the least you need a custom sump and possibly altered engine mounts - though I've a feeling Joe (FCSS) said they weren't really necessary. Plus all the other bits from above cars then custom fuel tank, exhaust, handbrake setup etc.

My build thread shows some of those bits.

Fiat Coupe Integrale

Anyone know if the dedra fueltank fits on the coupe? Never heard of anyone trying the dedra tank, only the q4 wich doesent fit..
Been a while since any activity on this thread iknow

No, it doesn't fit. But Daewoo Matiz metal tank fits perfect. You only need to drill and weld new filling hole

Your kidding me?
Where does it fit? How big is it?
Are you absolute positive the dedra one doesent fit? The one behind the axle?

Fits behind the axle, to the right side of a car because muffler is on left side


Dedra/Q4/Tempra 4x4 tanks doesn't fit. I'm sure, I've tried

Edit: I'm in a search of a cheap one. But friend is driving with Matiz fuel tank on a Bravo 20vt (soon 4x4). I could ask him for some pics of tank mount if you want

Hi Guys,
Does anyone know if the Dedra Integrale gearbox fits onto the Fiat Coupe 20V engine. I'm planning to convert a Lancia Dedra into an Integrale but haven't managed to locate a good 16V turbo engine.
Thanks

Hello, I am new to this forum and I was wondering of anyone could give me some advise on the 4x4 conversion of the 20vt coop? How ever I am 16 Yeats of age and due to college I can only work 3 days a week so i will struggle with funds
