Rb26 Maximum Stroke

[Capt. Raptor]

What is the maximum possible stroke that can be done for the RB26? Also how can I do this without buying one of those ridiculously overpriced stroker kits?

[ELMOHASA33]

buy a rb30 bottom end if you want more stroke personaly id stick with the rb 26 bottom why do you want more stroke any way ?

the main thing that determins stroke is the crank!!

the ONLY thing that determines stroke is the crank

[ELMOHASA33]

aaahhhh yeh sorry the ONLY thing

Pretty sure a member on here put an rb30 crank into an rb26 block and then used sr20 rods? and custom pistons to end up close to 3litres in capacity. There was a lot of machining that needed to be done on the crank to get it to clear everything and a lot of custom work. Have a search through the thread should be around somewhere

Most cost effective solution here is the RB30 block and crank.

Some people will say they're a primitive setup, but thats just their way of showing ignorance.

Any other option includes a new crank, and with that comes the big dollars

Good memory. 2.93L

^ ye and a cost of signifigantly more than a Jap stroker kit - being its ALL custom

[N1GTR]

Ah yeah, good point Ash, the cost;

Anyone thinking about going down that path should have $30,000 AUD to spend. Thats for the motor. That doesnt include a bare motor to use as a base

Yeah the guy who did it was an engine machinist with access to all the required equipment. Not really something for the average person to go for.
