Hi there,

I have the old serpent 977 which is brand new.

I would like to purchase an engine for it and looking for some advice.

I can get all three engines mentioned above about rhe same price and was wondering which one will be the best choice.
Is the vsr 03 same as r2103 just a bit faster?
will the r2102 be better because of the ceramic bearings?
Because if you see the o.s ceramics cost more than 100 dollars.

I would like ti have your opinion guys.

Thanks a lot..

If you have such questions then I doubt you will get the best out of the best engine. All 3 are good and fast engines. Do not get fooled by ceramic bearings, they will not add anoticeable thing than only the price and your mind will probably thinks it will be better.

Just make a choice and run it/

Hi Roelof,

Thanks a lot.

Do you have any recomendation out of the three?
Do they perform very similar?

I would suggest the r2103, you can find them at really good price. It is a fast engine. the non modifed one will be easier to tune.

I think after more than a year he did make a choice....
