RB23 clarification

[Ahh32]

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

my honest thoughts on this are just go the 2.2 and get the proper pistons if your going to run a 3037 you will need all the revs you can get tomei make the 2.2 pistons they are 82 mm should be plenty of bore left I know some one who ran this set up with a big rx6 set up and 256 cams and he made 600 hp you will need cams and some head work also consider usinga rb 26 n1 oil pump.

cheers
