I just ran the RB TXR last Sunday. Had ~3 litres through it and the engine ran great for the 45 min main, no problem at all. The quality is great, it is easy to tune and it sounds great with the 2668 pipe. The cooling head is kind of awkward, at least when it comes to attaching manifold springs, but is this is just a minor inconvenience and is probably for a reason.
The previous race I ran a Murnan Flash 3 and my best lap time were 1-2 tenths better with the Murnan. Both engines spool up very quickly and relatively smooth/linear. The Murnan seems to have a bit more on the long straight.
This is a helluva a deal on the TXR. If outside the EU then one does not need to pay the VAT (19% discount).
What are you waiting for? What other stock engine are you going to buy?
I have never tried the TX.
