Meanwhile a lot of people pm me because of my 4x4 – now I decided to put in some more detail to answer most questions of these people, who are interested in such a conversion…

My 4x4 has following spec:

Engine:
- 2,4l engine from Barbz
- big valve head additionally ported from previous F1-engine- builder Hartmut Lohmann (grinding shop for cylinder head BMW Formula One and optimizing of rods), Ferrea valves
- complete inlet system (plenum etc.) ported by hartmut as well
- C&B cams
- Big Garret IC rated for 600HP
- 4" inlet
- KMS free programmable ECU
- custom made manifold (Cufaro Racing) with T3 flange
- custom made dual flow exhaust with 2x63mm into 3" at the end
- GT3082R with external WG TIAL 44mm
- streghtened Dedra Integrale Box with main differential from a Delta Integrale EVO for a power distribution of 47% front / 53% rear
- Dual paddle clutch with very light flywheel (about 4,5kg) from Cufaro Racing
- complete Alfa Q4 4x4 drive train
- 19" Superleggera III alloys with 245/30 tires for a minimum of weight (21,8kg for the complete wheel - not bad for 19" and 245)
- D2 coilovers
- selfmade subframe brace, PU-bushes
- D2 8pot brake with 356mm in the front, Tarox 300mm brake conversion in the rear.
- power output with a compression ratio of about 8,5:1 and 98 Octane: measured 565 whp !!!

Thanks to Johns and Barbz, who helped me a lot to create such a HP- monster!

Driving experiences are very very impressive... a lot of boost below 3000rpm (about 0,5Bar), after ~3700rpm full boost (up to 1,55bar relating to the rpm – this to avoid too much torque, which could lead to a gear box failure).
Driveability:
My car is quite perfect to drive with really no problems regarding grip...
In curves the car comes around itself when pushing the accelerator pedal.
The drivability got much better!!! I would do it again...
The acceleration from 0 - 100km/h is awesome... you have to tell the co-driver that you now intend to accelerate... else they get scared :-)
My girlfriend does not want to drive in this car any more - because of it’s brutal speed-up... :-)
If overdoing, the car simply jackknifes…

What has to be done to do the conversation
Biggest problem is:
- the oil sump... you need to modify the original oil sump - we cut away some parts from the original one and welded it again... this was a sh... job!
Attention: provide enough baffle plates – else you will get problems with oil pressure in quick corners… (like me L)
- a tank: you have to cut away the spare tyre boot. I installed a selfmade tank - but there are some older rare Delta 2 with a tank (I think the five-door), which matches to the coupe (you need one which can be placed after rear axle).
- a new downpipe + exhaust - I welded a custom part.
The other parts are almost "plug in"
The engine moves about 1,25cm towards the right (then there is no space between the frame carrier and engine any more)...
The original engine mounts will do this little way.
Then you have to use the Integrale gearbox (fits perfectly to the engine) with the tranfer box and the original transfer box mount from the Dedra/Q4
To get the gearbox fitted you will have to use the gear box cover + mount from the 5-gear 20VT.
Some minor modifications have to be done to get all fitted...but not great...you need a good mechanic...
The complete rear axle will fit per drag and drop... you will need spacers, because the rear axle of 155 Q4 / Dedra is smaller than Fiat Coupe.
You can use a Dedra Integrale (advantage: longer gear ratio - the Alfa Q4 gear ratio is too short) or a Alfa 155Q4 as "donor"-car
advantage Q4:
- a real Torsen differential as rear axle
- power 47% in the front / 53% in the rear towards 54%/46% (Dedra)

These cars become very rare meanwhile.

I also realized, that with some bigger modifications it should be possible to use the 6th gear box for the 4x4 - the 6th gear box includes an adaptor for the 4x4 main differential.
Another number of crown gear teeth is the only problem...

Very nice

Where did you get your D2 brakes from? I have D2 305mm 6-pots on mine

wow would be great to see a video of acceleration if you have it

Link not working Juergen. Have you been on the dyno for a power run?

Excellent car! Please sell it to me

What do you think about the D2 coilovers?

wow.

what a spec! some seriously good work gone into your car!

any chance of some pics as that link didnt take me any where!

great stuff!

565WBHP with 4WD!!!
You got a dynoprint out?

No working links hosted below:



Taken for the tuning Guide:
"Stage 5 – 4WD/RWD with 650BHP+
Somebody build one please. :D"

- Looks like your the first (pending graph)


Amazing and

Please do following (should work):

To dyno:
I used a Reiner3000 system - four test runs on two days with comparable results.
This is the only onroad system with German Tuev accreditation.

Awesome - great work!

Fantastic conversion, nicely done

Wow what a conversion! It looks very tidy indeed

very impressive, and very well done for the effort that youve obviously put into it.

now . . . i wanna see a video

Ninja

Fantastic job!

Update: New Pics added!

Thank you for for plaudit... my garage did a wonderful job - I also got German Tuev, because of the good work - Car condition now isn't worse than the original car...

Juergen

Wow amazing coupe!!
love the subtle styling too!!

I can't see any pics. The link doesn't work

I get this message: Diese Session ist nicht mehr gültig (Timeout). Bitte schließen Sie dieses Fenster und melden Sie sich neu mit Ihrem GMX Account an.

Lovely car

cracking car mate, is this the first 20VT 4x4?? I know there are a few 16VT 4x4

wow! well done! and im even more impressed that the car looks totally stock from the outside.

redd

Nice work Stichl, now get some videos up on youtube

Amazing conversion! Love it, as said - we need videos!

Wirklich bewundernswert....

Very well done,the car looks totally stock from outside.Buth there,s a monster under it

Amazing work!

Would you like to come over to England next year for Ten of the Best?

.....and sneak into the FWD category?

Seriously - I'm sure the club or it's members would sponsor it in some way if you were interested.

Whilst it would be nice to see it at Ten of the Best, the truth is that it would very quickly be banned from the FWD class and it would be totally mullered in the 4WD class (you need 750+ bhp to be competitive in that company)

Still V. impressive though - can't wait to see some performance stats

don't forget this is WHP and also on 98 RON fuel. would like to see what quarter mile it could do with race fuel.

I'd donate a tenner for fuel... that should last....er... a couple of minutes...

I bet you'd want to be passenger for those 2 minutes too

Good work Juergen. Need to see videos of it on the Autobahn

Interested to know the 1/4 mile time with this monster as well.
