TT36 or 39?

I was thinking of getting the raptor 30 with the tt39 engine. However, when i checked, i found this engine doesn't exist officially. It doesn't appear in the official TT site. could this be mistaken for the TT36 engine instead? However, i've heard of people mentioning of replacing their 36 with a 39. I'm really puzzled. One more thing, would it be better to dispense with the TT engine and go for a OS32 instead?

the 39 comes with the v2 the 36 with the v1 both good engines
as for os 32 well os is os an exelent engines but not necessary
unless your tt gives you extremely lots of trouble and even then i?m sure we could help you here on the forum
