My gtv6's motor
Let me tell you the story of my gtv6'motor who was smoking too much in 2011, so I decided to rebuilt it
Re: My gtv6's motor
Are these tubulure échappement from Sodemo? I was looking to buy one for years but rhe last person I contacted said they couldnt find someone to make the bends. Very nice build!
Re: My gtv6's motor
More info on this link :
viewtopic.php?f=17&t=4352
So they are DEVIL SODEMO, they are no more available and very rare.
Mine are oval diameter 36-40 mm, this fact make them easier to mount.
Look the other model (circle diameter 40 mm) of my friend David
The manifold touch the body, he has to cut the body.
Of course these circle 40 mm are best for power on trackday's car but not very welcome on a road car you don't want to modify to much.

Re: My gtv6's motor
Here is the story of the V6's rebuilt :
I bought brand new injector like stock :
http://cgi.ebay.com:80/ebaymotors/SMP-S ... 5ae2052acb
With my friend Marc we took off the motor !
With 600W light it's more confortable
Amazing, it was easier than the 4 cylinders
And after have beers of course !

Re: My gtv6's motor
As I know more 4 cylinders than V6, my friend David came to help me many times, thank you David !
Heads are off !
Hey gatouille don't you forgot the second one ???
Oups sorry, I told you I know more 4 cylinders with ONE head
The sister Alfetta is looking at the work...
Heads and cams are in very good shape (only 76 000 km) But I decided to make the job as it is a used motor, because everything is opened, and I think it's time to do and easier than later.
Valves guide seals are out of order and also bronze exhaust valve guides (only mounted on earlier GTV6. They are a well know weak point.
I will replace them by brand new cast iron one.
1,2,3,4,5 and 6 pistons ouch !
Pistons and liners are ok, liners will be "honed" and I use brand new piston's rings
It's important to always keep pulley, Crankshaft and flvwheel together because they were "balancing" by Alfa works.
Some of parts will be glassblast...

Re: My gtv6's motor
Later:
It' time to clean everything
Isn't it nicer ?
This tool is very usefull for cleaning old motors
Clean and a rotative brush.
Clean pistons
What a job, why am I not richer I could pay someone to do all this job

Bad news guys, I played LOTO, but I didn't win !!
So I have to do myself the second step of cleaning !!!
Spare parts are drying, thez nicer on photo than the real
Here is the "target", I'd like to do the same job as on my 2 liters twin spark :

Re: My gtv6's motor
Cleaning always cleaning
My wife hope to have same husband's work at home
Oups! I made a mistake ans the head is hurted
There is no importance we are going to machine heads about 0,9 mm !
A 155 V6 2,5 L (motronic) for 100 euros
I planed to take the camshafts, because they are very intersting (profile are between standard GTV6 and 164 S (QV)
Look and lift is 9,6
Sorry in french but I think everybody will understand (in case of not you "just" have to learn french )
I hate working on FWD, I hate
Here is exhaust with the Devil SODEMO, I'll change a bit because it's too rigid.
The car which had these manifolds crashed so there are not in good shape.
As usual, because I'm a very little and humble DIYer, I will use my "network" of friends to repare these manifolds...

Sorry, i'n not serious at all
Thank you nice tool !
I have to clean I guess
6 musicians (I hope so)
Let there be light, drums, guitar !!!!!!
Sorry, you guess I am afan of AC/DC, liners have been honed

Sorry if my english is not perfect at all.

Re: My gtv6's motor
Cleaning is easier and best when glassblast !
Thank you Franck who made this very nice job for...nothing
We could believe that have been painted...
Franck was desapointed because some parts wern't nice enough, what do you think ?
It's exciting, isn't it ?
Guess the weight of crankshaft, pistons rod liners....

Re: My gtv6's motor
Sunday 6h40 in the morning, you can imagine how well motivated we were my freind David and I !
It's time to rebuilt the motor !!!
#@** The son of....his mother
on part for Crankshaft's got a difference,
I mean part #17
Most of the time this part's got a "omega" profile like the greek letter I mean, but earlierst V6 had a "half circle" profile.
It's hard to find them. I kept the genuine one which was ok (2,33 mm) mini 2,31
Il sera bénéfique de remplir le circuit d'huile façon ZP par la sonde pression d'huile, pour diminuer encore le temps "sans huile" lors de la remise en route.
De plus je vais faire tourner le moteur au démarreur sans bougies pour bien amorcer le circuit comme je l'avais fait sur le Twin Spark.
Il est 11H30, David a bien mérité d'aller voir ses eléments peints de sa voiture de circuit chez le carrossier, il piaffait d'impatience
When mounting the oil pomp IT'S VERY IMPORTANT to make it turn as you mount screws, that prevent failure or (on 4 cylinders breaking delco)
Unfortunately camshaft ok my A55 V6 are different ! They are shorter !
Impossible to moint them in my heads.
So I decided to use regrinded camshaft, very good quality and cheap :
http://www.dbilas-shop.com/Products/Per ... _2945.html
I choose the Road profil
V6 2,0 - 2,5 - 3,0 12V
Applikation : Road
Duration: : 272
Peak timing: : 110
Valve lift: : 9,1
Lift at TDC: : 2,7
Valve timing: : 26/66 - 66/26
Valve clearence: : 50/25
One of my friend choose the rally one because he use only the car on trackdays
V6 2,0 - 2,5 - 3,0 12V
Applikation : Rallye
Duration: : 290
Peak timing: : 105
Valve lift: : 10,7
Lift at TDC: : 2,8
Valve timing: : 40/70 - 70/40
Valve clearence: : 50/25
Price is (with nitrured) about 400/450 euros 2 camshafts, which is not so expensive.

Re: My gtv6's motor
Culasses are almost ready, new guides, valves and seats have been "machined"
Later I will machined the head 0,9 mm less because my CR target is 10:1
"hélicoïl" kit 7 X 100
eMost of the time we meet trouble with this screw that I decided to use Helicoil kit.
Rule is simple for 7 X 100 you need a hole of 7 mm.

This part is like brand new
Alternator will have the same "treatment"

Re: My gtv6's motor
Bringing the GTV6 without motor but with A/C to a garage specialized in A/C
.
All seal will changed, compressor's oil...
Head during machined, thank you Jivaro, very nice job !
I hope he know his job, as he used to work on Peugeot 905 and Formula one !
6 brand new but stock injectors :
My target is to have a road use 2,5L with little more power and torque, wait ans see !
