Nice. Man I gotta start my RSR build
Very Nice! Which kit and scale?
This boxless 1/18 Autoart I bought cheap on ebay a while back
What a awesome model!

My good model friend of Riccardo always tells me: "the man who makes models with legos"
[lol]
Replicating the slightly V-shaped central bracket that follows the physiognomy of the monobloc is possible to scratch but it is a long job.
My Danish friends served me the solution (as usual) on a silver plate.
I Take 2 bricks, created the loop for the central frame and created the loops for the other lateral ones.
This frame will become load-bearing for both the engine and the turbo. To center it at the "v" of the base, the perfect position falls on the side of the side chassis struts.
I will open a slot in order to drop from the top and set the frame which will then be fixed to the monobloc by means of 4 studs (as on the real RSR)
On the central plate we will then have to think about how to fix the Turbo and the heat shield.
A lot of work to do, but i'm think on the right way.

I started with the main part of this conversion: the turbo.
Making me the turbos by myself was and is a difficult to made and also impossible for me.
So for the 0.70 cent I took a keychain with a compressor (or cold side of turbo unit) attached.
Given the generous dimensions, the problem was the exhaust side turbo (or hot side) which also on the RSR is slightly smaller in diameter. Having various pieces of the mp4/4 .... I borrowed an IHI compressor (which will then be modified in the connection for the downpipe to the exhausts and will be modified for the exhaust outlet)
In the middle I have the hub on which the various lubrication pipes will then be applied.
I drilled the hub, I disassembled the compressor and drilled and and then I modified the turbo of the mp4 to insert a 2.5 m nut
Starting from the compressor to get up to the turbo, there is a 16mm Allen key that crosses the whole body and screws onto the turbo itself .... practically in reality it would be the shaft, in the model it is the hub that holds everything together the whole turbo compressor unit .
Once the turbo is paired and created, it's time to fix it to the crossbar.
I created the bracket that supports the turbo with 1mm aluminum. I pierced the "breech" of the turbo, fixed the bracket and finally I bent it in a U shape to go and slip back into the usual turbo screw-shaft.
Once shaped, I then fixed it to the crossbar using 2 Allen screws. Given the weight and size, the glue was absolutely not practicable, furthermore making everything removable is easier for modifications, coloring and tests with the exhausts.

It'll turn out amazing, don't worry, I used the same method for my NSX
and with the intake pipe
Your foundation looks super solid. And this is what I always tell people when they say "I hope I can have the same skill some day!", it's not skill, it's just patience and using a good method. It was your first attempt and look at how good that looks
