Questions: Technical development of an R2 rally car
Hello
I have a couple of questions regarding the technical regulations and development of an R2 rally car:
1) If the car in question does not come standard with a 1600 NA engine, can one put a 1600 NA engine in it so it can comply with the rules?
2) If so, what is the rules of putting in this engine, regarding manufacturer etc?
Do anybody know the answer to this?https://www.facebook.com/noseendfirst?ref=hl#

Prior this year it was not possible to put an engine from other car but since 2014 it is possible. This rule was changed to allow Opel to homologate the Adam R2 (no stock Adam 1.6 exists). The engine must come from the portfolio of the same brand. I don't know the exact rules though.

By the way I expect soon some R2T option to come. The atmospheric 1.6 engines are disappearing, for example the whole VAG group uses them only in Russia and Asia. I guess it will be something like 1.2 turbo which would suit all European manufacturers.

Did Skoda not homologate a Engine only for the Fabia R2 car ?, a few years ago ?. They did not have a 1.6 Petrol car in the Fabia road car range.

No, they did have the engine in Fabia but only on Russian market. That's why the homologation was so late that time because the production in Russia was quite slow and they were waiting for enough cars produced. Besides that Škoda Motorsport was not working on the car as it was a private project. They only provided homologation and helped with several tests but that's all as far as I know.

Looking at the homologations, the Adam’s engine is from an Astra.

Looks like the turbo engines will be allowed from beginning of 2015.

That's somewhat strange. Up to 1333 ccm turbocharged in R3? Current R3T cars have up to 1620 ccm.
