hi guys,
I am building and RB2.3 and before i pull my engine apart just want to clarify a few things.
I am using a RB25 crank and rods with 4AGZE pistons from a AE101 levin, as i believe that these are forged & light weight. Now Question time:
1.The piston pin hole dia. is 20mm, is that the same as RB25 rods
2. 4AGZE pistons are 81mm, current bore size is 78mm. that's 3mm or a lotta thou. Is there enough cyl. wall thickness to be bored out that much, also. I have been told that there will be problems with cyl. flexing, just want to know people's personal experiece. I am going to 'Cryo treat' most parts of the engine, so hopefully that should cyl. problems if there are any.
3. Anyone know prices for 4AGZE pistons, must be from a AE101.
Price for 1mm metal head gasket
Price for 'Nismo' Big end crank & con rod bearings
4. 1 more, i am running a HKS 3037s turbo, any advise for camshft selction.
Thanks in advance
