i am interested in using an RB26 in my next build up in circuit racing. but to be honest i have no experience with the motor. i just want to know how much HP can the stock internals hold.?????? what can it be bored out to? block quality?? thick cylender walls?? stock red line?? red line with good rods, rod bolts, rods etc. (stock i believe that it can handle 8500 rpm so with the right built up it should be able to handle upward of 9000-10000rpm also how much can the manual tranny hold??( are there two diff. available. one RWD and one for the AWD set up, who makes the tranny). so you know i usually shoot for around 700 rwhp with great response that can handle the 8000-10000 rpm range.

s/t more, whats up with the rear end, diff, cv joints. etc.??? strong?? weak points to consider????

hate to seem like a dummy. but i just want to get a plan together, thats is why i need to know what this package can handle. i have looked all over forums and on the web but cant find this simple info. some in australia gave me what it can in kw. i dont understand that, i need HP ratings.
my experience is with the SB chev (late model racing 900hp), 4g63 (drag, circuit ) and 2jz (drag)

thanks for any info given on said engine and tranny.
just a last note. i am not just asking to know, if i like the potential of this motor i will be running it by late april

 

are there better years or block numbers than other years??????? or other advantages over others???

 

Stock RB26's will see 9,000 RPM on a stock bottom end. You will want to upgrade your valvetrain. The engine also has a reasonably short stroke, so its possible to bore/stroke the motor, with out too many ill consequences.

What kind of budget do you have for the build? What about time?

There are plenty of 1,000+ HP 10,000+ RPM RB's floating around.

There are also rb30e engines mostly in australia, people have been running these blocks, with rb25 heads for a while.

This pretty much lengthens your stroke (rb25: 71mm / rb26: 73mm) to 86mm. Wich pretty much leaves you with alot more low end torque, but lowering your revs.

Again, it all comes down to money. If you need low end torque, building an rb30 would be more cost effective than stroking your rb26. If money was not an issue, I would go with a 76mm stroke, giving you the best of both worlds.

 

thanks man, i always put the best stuff in my motors, dont worry about the $$$, i can sell stuff i have, i usually come up with the means.

so how much hp can the crank, rods etc. handle stock
any info on the maual tranny.

 

This would be a good place to start doing research.

i hate RB motors...they are gay!
its not fair that a motor like that see's such a large power gain from basic stuff like intake and exhaust..
