I'm at the stage of machining out my transfer housing, which has a standard non turbo 1st motion support bearing. I have always ran a turbo support bearing in the past, but is there really a need for it?

Does anyone on here that is running 200bhp + run a standard sized support bearing and had any problems?

If there is no need for a turbo bearing, that'll save me a lot more machining! :)

Haha you could be right! It has crossed my mind, that every rebuild I'd have to buy 2 of the fuckers, that also never seem to be in stock.

Ah well that sorts that out then! I had a measure up and there's only 3mm difference in the two bearings, and the castings appear to be identical just bored different sizes.

Ages ago when I had access to Romax and a lot of contacts at various bearing manufacturers, I concluded that the "turbo" bearing had just a 25% increase in load than the stock bearing.

I personally have always used them, but seeing as how they are getting more, and more expensive, don't think I'll bother as/when my existing bearing craps out.

I suppose the other issue is the original bearing was intended to last 75k miles or whatever they concluded was acceptable. If my bearings do 10k before being swopped out that would be an achievement.
