Rb20 With 4agze Pistions

[Guest Jordy32]

hey ppl, i know theres has been a lot of talk about using 25 or 26 crank & rods with 4agze pistons to give you 2.3/2.4L engine, but was just thinking of rebuilding my rb20 & just changing pistion for some forgies.

so my question is, can i fit 4agze pistions & just bore it to suit.

i know that the head may need some machining but will the pistion be ok with the block deck height?? & are the 4agze pistions forged? if so what is the part No.?

thanx for your help. cheers

The 4AGZE (101 levin) piston height (bottom of pin hole to top) is 40.5mm

RB20 ones are approx 44mm

4AGZE piston diameter : 80.5mm std

4AGZE piston pin is 1mm smaller. (need bush made)
