Few questions on RB25 Gearbox.

Hey there

So atm I'm interested in a R34 that been listed for sale at sorta reasonable price. Only issue is that it was originally an NA and has had an RB25 series 1 from a 33 put in. The gearboxes is what I'm abit worried about though. 

I'm aware that the r33 and the r34 turbo gearboxes are similar. 

But what Im wondering is how much Horsepower can a 34 NA handle?

How can you tell the difference between the NA and the turbo gearbox?

And anything else to worry about you can think of

Dunno about laws in QLD, but that combo would be impossible to rego in Vic (older engine in newer car) without some hefty engineering costs.

Generally (generally!) speaking the NA gear is good enough to handle the STOCK output of turbo motors. More generally speaking think longer term owning the car and ask yourself is this a can of worms you want to get into?

It'd usually be smarter to save a little more and get something with less potential headaches going forward.
