And here we go once again...
The whole story starts again.
The reason that was causing the lack of power was low compression (around 8bar = 116psi ), so I took the whole engine, and drivetrain apart...
So this time there will be some bigger modifications.
- forged pistons
- equal length exhaust mainfold
- Lancia kappa intake
- T3/T4 turbo
- Gr.A head gasket
- bigger oil cooler
- bigger AC
- kevlar clutch
- 4piston brakes
etc...

Here are some pictures:

So here is what caused the lack of power...
So the hole is 1.5 times bigger as it should be, as the red line shows.
So I had the very first VPT (Variable Piston Timing) engine Q4 ever...
Patents Pending!

Nooo way... That is some handy mechanic's work...
Probably previous owner...

No, but it was moving back and forth each stroke.
It sounded like the valve clearances were really bad...
(Clattering noise.) :S

[wrinx]

Sorry, that's what I meant, so it messed the timing

Very strange...can't think why anyone would do that. That slot is for a woodruff key I presume?

That's a weird one, I've never seen that before.

Maybe a hamfisted mechanic lost the woodruff key and had to file it out for a bigger one?

Should have got Jack to slacken the nut off, it would have never come loose then eh...

Please let me know how they fit and what about rims clearance.

Ok, as soon as it's ready, I will tell you and send some pics.
I'm going to use standard 285mm disks, because they must fit under my 15" AZEV rims.

I'd like to keep the standard disk too. A little more breaking power at the front wheels wont be bad though.
From the other hand, I do trust more the good old piston type calipers. And if they are 4 piston will be great.

Waiting for the pics as soon as you complete it.

Good luck

Were the GTV seats a lot of work to make them fit?

I wont try then.

So when is the wooden trim coming out then?

As soon as I figured out, how to "remove" the holes, witch the previous owner drilled for 2 leds and a cellphone-holder...

If you want this kind of seats, than better go for the 145 TI, I think they have the same bolt pattern...
