wow this is gonna be a great project, personally id go for the 20vt imo its a better car and you have already done a 16vt might as well take it to the next level. just out of curiosity when doyou aim to have this finished???

Fantastic!

would even help towards me converting the marea to 4x4 should i be able to afford it in the future!

i voted 20vT

Is it straight bolt off bolt on to fit it to a 16v? I'm guessing you'd have to modify/fabricate some parts?

no its fairly simple nothing to fabricate. All you have to do is to make place in the back where the standard tank lies. This is for the 16v engine. I personaly wouldnt make a 20vt there is nothing to gain but the fact that you have a 20 vt everything else is more complicated needs more fabrication........

Got to be 16V, even if just for the integrale heritage. The lack of horses isn't going to make much difference in the long run as I can't imagine someone who goes to the trouble of a 4x4 conversion is going to keep the car standard under the bonnet I've never bothered even chipping my 16VT because I reckon its a total waste of time on a FWD car, if it was RWD or 4WD I'd change my mind.

Make the conversion as cheap and simple as possible and save as many coupes as you can so you can get a bigger market and prove the concept. All you 20V owners should keep your nice 20v examples mint and buy an old 16V for the project, they're not exactly expensive!

Then when we're all happy with the idea of the 4WD coupe and there's some experience of the issues involved - do a kit for the 20V afterwards!

Actually, it just so happens that I have a 16VT which is coming to the end of its economic life.....

An engine or the car?

The 16v has already been done! So why do it again?

And how is there nothing to gain by doing a 20vt conversion? If I come into some money and the concept had been proven I'd go for a 400bhp 4*4 20vt!!

Look my friend is going to 700 hp on his 16v i dont see any point in making a 20 vt . At 16v it all fits you have a 4x4 and I am sorry but i dont care if someone allready has a 4x4 16v coupe i would build the car for me not for others. 16v is more tunable weight distirbution is right all components fit Its more reliable than makeing a 20vt engine fitting the 16vt tranny. At 16v conversion you taje the suspension down you place in the 4x4 kit that i am selling conect everything put a gas tank in it and you are fiarly done. If you want to have a 20vt 4x4 than oyu have to fit the engien to the tranny stick everything in the coupe supsenison wont gfit
anything wont fit. for 1400 you get everything that you need to fit a 4x4 into a coupe than you buy a gas tank and if you have a fast mechanic or you are able to do it you have a 4x4 coupe in one week of work.

The original theme of this thread was someone asking *other people* which they would like to see. Seeing as the 16v conversion has been done, a lot of people have suggested the 20vt because its more of a challenge and it doesnt already exist :).

By my knowledge it exists in hungary. The guy who made maps for our Group A impreza told me that it raced rally cross.... And anotherone is being built whit my drivetrain in Malasya ( the owner still ows me money !) and im shure ther are more so your only argument is pointless :). I am not talkig about who will you impress i am talking about what is the best the most efficient and cheapest solution to the problem.

Regards Klemen

It's not the cheapest solution if you have to buy a 16VT first though! There may be 20VT owners who might consider making their cars 4wd if there was a kit or set of instructions and parts to source available.

16VT is actually heavier than the 20vt - not sure about the disribution of weight though.

This kind of project is going to be a one off though isn't it?

There are not many coupe owners that are willing to spend more than a couple of grand on tuning.....I admire you for going for this from an engineering perspective, but in no way is this going to be a commercial excersise. Therefore pick whichever car you like and go for your life and keep us posted. I'd like to really see you go to town and get some active yaw control in there as in the evo's....now there's a challenge for you.

Good luck with what ever you decide to do.

Well i hope you all know that the drivetrain form an 155 q4 fits to all mounting points of a coupe suspension. Fabrication is only needed for mounting the propshaft. Front and back bridges fit directly bolt to bolt on the chasies of a coupe. Dont understand me wrong my drivetrains fit directly to a 16v but you could modify to fit to 20 v i am just staiting the cheaper faster more reliable way. Allso the q4 drivetrian has the torsen rear unit not open one as does the dedra.

There's a guy over here considering doing a similar project...

Now what I want is the 16v 4*4 turbo diesel

(no, not jacked up on jumbo tyres! )

Well get us some information on it then!

And there is more to life than efficiency!

I know that you are talking to a owner( smell the irony because im not driveing it ) Of an alfa 155 Q4. But looking at it as a race car mechanic 16v is the way to go it is as simple as that but as i said my kits fit them both so if i sell one its the same for me i am just trying to save the man a lot of nerves!

I agree that if you are going for a big power engine then the 16vt is the way to go. For a start it is very hard to get a reasonably priced aftermarket ECU that can handle the 5 cyl properly here in the UK....

Rob40 runs his 2.5 20vt on a DTA ecu.

My friend run his on 550 hp on stocl eletronics and now on 700 hp he will still use the stock computer. im talking about the 16v engine

...and he probably has a custom trigger wheel to make it work....

This is his car

I have seen this car spec over on Guy Croft forum, has he got the GT35R on it now? - very impressive this is his car right?

http://www.guy-croft.com/viewtopic.php?f=5&t=1089

4x4 has to be an advantage at that sort of power

Now he has ripped it appart and is building it to 700 horses hopefully he is finished soon . WHit this kind of horses 4x4 is the way.

i want to see a 4x4 20VT

Hi guys I am currently a Fiat stilo driver from greece, but I am planning a project based on 4wd coupe.
Info that I 've already gathered:
1."plug and play awd" can be taken from 155 Q4, dedra (not delta)integrale, tempra SW 4x4, dedra SW 4x4.
2.there is a 20v 4x4 running in greece around 450hp and working very well!!
3.you have to sacrifice the visco at the front. then you will have
free slip diff at the fron - ferguson clutch for rear distribution - torsen rear diff

Info requested:
1.is it necessary to switch to 5speed gearbox?
2.does anybody knows another way to have a limited slip diff at the front while in 4WD? like in Lancia delta S4
(non viscous LSD-ferguson-torsen)??????

Please do the 20VT - I NEED a 20VT 4x4 on my drive!!!!

Would be good, watching with interest!

correct me if im wrong but fitting a 4wd system to either a 16v or 20v turbo wont lose hp as the 4wd will use the hp alot better and get it to the floor over 240bhp a fwd becomes unstable and is the recomended power to use but a 4wd system would use all the bhp as its supposed to be god knows why fit didnt make the LE a 4wd then it would be a unique car

but 16vt gets my vote maybe a dying bread but has heritage and could be converted in less than a week as the dedra rear beam is a direct bolt on all you need is a new fuel tank and new exhaust

long live the 16vt
