Porsche 911 RS 1972.......Turbo conversion 1/8
Re: Porsche 911 RS 1972.......Turbo conversion 1/8
I modified the housing of the steering box by raising it to make the arms work better and without having the effect of a spring on wheel hubs.
Furthermore, to remedy the problem of too high front shock absorbers, I drilled the stems deeper to have more space for the screw and finally I shortened them by 4mm.
Now I reached the result what I was looking for

Once I found my right set up, I arrived at the first "point of no return".
Using the image of his sister RSR, I removed the trunk strut of the bodywork and chassis ... with the rear outside turbo they will no longer be needed.

LOL!!!!!I know….ultra low ride is a mix of religion and disease for me
Re: Porsche 911 RS 1972.......Turbo conversion 1/8
I continue the opening of the engine compartment in the crossbar area; I start thinking about the turbo, exhausts and intercooler group.
I installed the engine to calculate the next works.

The turbo will be positioned in the zone like on its sister RSR.
i started with the mutual help with Eidai parts.
In the RSR the engine frame is not complete as on the RS, the engine frame towards the opening of the engine hood are not present and the engine is fixed with the aid of a trapezoidal frame directly connected to the frame side members.
This frame as well as being a fixing point for the engine also has the function of supporting the turbo.
My idea is to replicate this frame using the Eidai one as the dimension and matrix as it fits perfectly onto the DeA chassis.

Each kit has its flaws and this is part of this "game"... but what makes me smile / angry is the extreme difference in the detail of the monoblock.
The lower monoblocks in comparison are always the Eidai and the Dea.
In the RSR the fins of the cylinders and the 6 connections of the exhaust manifold have been reproduced, in addition the 4 barrels (I think they cover the studs that fix the heads) are removable and there is a little details of nuts and bolts.
The gearbox has greater detail and is much more realistic than the Dea gearbox too.
The eidai is almost 50 years old .... the porsche Dea is maybe 3.
The heads and cylinders of the DEA cannot be looked at. This RS was created to mount the original exhaust equipped with 2 side silencers and the central one.
By turning it into a turbo all this exhaust will remain in the box.
The big problem is that Dea (in addition to having made a very coarse monoblock) has planted pegs and made some screw holes in correspondence with the future connections of the 6 exhaust ports.
So I rest my heart in peace and I started sawing and filing to smooth out the first of the 2 banks.
My idea is to try to reconstruct the fins (or at least part of it) with plasticard and to build the exhaust ports from which the 6 manifolds will start, which will then converge to the turbo ... as the image and likeness of the RSR

Nice. Man I gotta start my RSR build
Re: Porsche 911 RS 1972.......Turbo conversion 1/8
What are you doing?
Re: Porsche 911 RS 1972.......Turbo conversion 1/8
Very Nice! Which kit and scale?
Re: Porsche 911 RS 1972.......Turbo conversion 1/8
The cylindes group is also smoothed.
But before starting to think about the exhaust manifolds, I must first put together the engine in its total size.
The upper part does not distinguish between the head, fan cowling, fuel system… it looks like the whole cooling cowling but in reality it is not.
The Porsche engine is framed on the front… ..that does not exist on the front of the RSR… well, I started by eliminating it here too.
But by removing it, all the crack remains due to the absence of the front frame piece.
I removed what I needed and started working to close this gap.
Another problem: the timing covers. The carters have an external rib which in 1: 1 are used to fix the front part of the frame that is no longer there.
The right timing cover has the correct rib or eyelid and at the right height.
On the left instead:
- no right height (remains too low compared to the upper half colored in silver)
- no rib
I acted like this:
- I raised the timing cover by calculating the missing thickness and placing it at the same level as the upper part.
- I took out the wrong rib
- I filled the loop for the screw
- I recreated the most protruding rib
Finally assembled everything to see the overall effect ... .. the screws on the casings will disappear ... but for the moment I need to keep everything squared

Viewing the 2.7 engine pics online, the Dea engine brings to light other inconsistencies and mistakes.
The top of the timing cover has ribs found on other flat sixes… but not on this 2.7
With the dremel I smoothed out the ribs and reduced the height of the upper timing cover bolts
I continued and I think finished the operation of opening the engine compartment, eliminating the last crossbars.
I also cut by eliminating the original engine mounts, as on the RSR the engine is supported by that trapezoidal frame mentioned above.
I repositioned the engine: the Eidai frame has a correct wheelbase and if my Porsche had been high from the factory even in depth I think it would have been fine.
Having lowered the entire car body by 14 mm if I replicated it on an equal footing, I would have an inadequate ground clearance and the turbo downpipe would be scrap on the ground.

Cool! Isn't that a sealed model?
