RB20 to RB23 what Pistons?

[RedDrifter]

To build up an RB23 from a RB20 I have been told that you need the RB25 Crank and Rods but what pistons are needed for this conversion?

The reason I ask is that I intend to do this build up. It's different so I thought why not since I have the rods and crank already(RB25) and an RB20 bench motor that I intend for a tear down and rebuild.

Any ideas people.

you need 82 mmm pistons zooom recons you can use 4agze pistons not sure about thne there is an 82 mm head gasket avaliable from tomei.

I alway thought about doing this but figured I'd go rb 25 instead or some thing and the some thing else is the sr.

there was one for sale in japan a little while back with a t88 made 595 or so

Sounds interesting a small T 4 would probalby be good on this type of combo depends on what you want from it. to make it worth while I would do cams 264 or so and a bit of head work. your imporvments will be mainly in torque area.

If you get on SDU a guy with the nick JONJON has done this in japan

good luck
