RB34 In Production

[mcfly]

Spool Imports out of Australia i believe is to blame for this

86.5mm bore
95mm stroke

based on rb30 block

This is a picture of the crank they made

[rb-racer]

why is this new, the engine has been around for two decades. I just thought someone would have done it already.

[TougeJunkie]

That would be nice, while on the subject of Spool what do you guys think of the Spool connecting rods? I wonder what the safe rpm range would be with 95mm rods on the moded RB30 block

[DrMango]

Wow. does this mean that much more potential for that much more HP to be worth it really, over like an RB31? probably going to cost a fortune..

I guess it depends what you want from your engine and what application its going to be used in. I still don't believe this will work as there just shouldn't be enough room in the block for a 95mm stroke

[Allan74]

The Block is still a point of concern for Big HP builds and is expensive to brace/Prep.

That RB34 will be nice, I am sure.......but who wants a 6500 RPM spinning 'RB' ?

[mcfly]

you "could" still spin a 95mm to 8k

[Allan74]

Well, fair enough. I guess it's only -5mm on the Rods, so we will have to see how it all plays out and what they have do to the block to keep it together with that big-ass crankshaft.

How strong is the rb30 block
any differences between the turbo and non turbo in regards to strength?
