Thought of that first, but where should you draw the manifold? The hydraulic pump effective blocks the passage where they draw it on 205, 309, 405 etc.

That exhaustmanifold looks familiar, I think it's a Dutch one 8)

I'm not really concerned about the exhaustmanifold, because a friend of my is a very good welder with all certificates, but I'm more concerned about the returnpipe to the downpipe.

First I'll finish the body of my BX and in the winter I planned to do the turbowork.
Ofcourse there will be pictures!

On topic: V6 24V will be difficult, but V6 12V is not that hard. But in Holland it needs to be retested because of the paperwork. (4 cilinder > 6 cilinder)

I think that fitting a V6 will add a lot of weight in the front and spoil the weight distribution of the car.
It would be very interesting to fit a supercharger in a 16v, both low rev torque and high rev madness :twisted: :twisted:

Presumably the V6 is an alloy block as well then? I can't see why it should be too much heavier. Stick a boy racer sub in the boot, that'll even things out :D

I'm guessing the later 60 degree (24v?) one would fit in more comfortably, sharper firing angle = smaller block...?

The V6 is not so heavy, the power will easy compensate the extra weight 8)
Ive seen a 205 with V6 AND turbo somewhere on the net, if that work in a 205 it will work in a BX :)

WYD: Thats right, the manifold is from http://www.dp-engineering.nl.
Its same here with car testing, it can never be legal in sweden with V6 or turbo. You have to build it back to original before the test every year :(
Some 205Mi16 slips through just because they dont notice it :wink:

We are talking monster-BX here dont we? :D

My thought is that even if isn't is so heavy the V6 It will more weight on the front axle. This in my opinion will spoil the handling of the car. If the car is used only for drag racing or straight roads and highways ok.
Downhere I enjoy driving at slipery tight mountain roads and that spoils handling spoils fun.
A V6 conversion is very interesting though and I hope if anyone does it to inform us about the outcome.

No they are not!!! I can get M45 quite cheap

You don't want Rotrex any near Your engine! Rotrex is a belt driven turbo and posesses all bad things from turbo and SC world.

Wait until they come up with CVT on Rotrex, unitl then stay away

Why do You think so? You can always send it to me and I'll give it to clutch specialist over here who can make a ceramic coat over it, or tvaron coat...You name it.

I've got a lightened flywheel and hard sport-clutch.
Fitting a turbo doesn't unofficially give problems for roadgoing. Official it's not allowed to have more than 40% powerincrease, but.... Originally I've got only 110Hp and it will be about doubled next winter :P
They only look at number of cilindres and what kind of petrol is used.

Many here drives 205 and 405 with turbo, they report that the original clutch slips about 0,5bar/200hp.

There are a lot of specialists here too, and a good market of better clutches too, but as i say, it costs a lot of money.

Adding a better material (more traction) on the clutch and retaining stock pressure plate should do the trick for 300Nm+

I know, a cheap trick is to use a Saab turbo pressure plate.

From old saab 900, up to -88 or something.
I know the clutch diameter is same (215mm) but i think some mods are required. Its probably the bearing and the arm holding it. Ill try to ask someone who did it.

The Saab clutch fits on the guide studs, but not bolts. New boltholes are easy to drill :)
The Saab plate press 600 kilos and original 16v about 400 kilos.
