I bought some Z20 pistons last night for my long rod L20B build up, & was worried where to get the Z20E rods. Found an American site for Nissan utes, Nicoclub.com , Datsun Pickups General Chat‎ , that gave the length of the Z20E rods as 152.2 mm. Looking through the Spool con rod site ,they give the length of the Nissan con rods they sell & 152.2 mm is the length for the RB30E engine. So I can spend about $660 for a set of 6 rods & have 2 spare, or I could go down to the shed & strip the RB30 thats been sitting there for a few years. Just hope these 86 mm Z20 pistons have the pin height for the Z20E. Oh well, for $75 bucks it's worth a gamble. Maybe the RB30E have the same pin heights as the Z20E at 31.75 mm.

Ive got l16 here if those suit. Otherwise I was going to use in an l18 possibly with milled pistons

the problem is the rb30 rods are thinner at the BE

quite thin actually L series 26.x mm vs RB series 21.7x mm

Z20 rods are your only choice and the best fit but there is also a possibility
if you are going H beams to look up a late dodge 2.3 L4 engine which has the
152.5mm length, 53mm bore and slightly thicker BE width but I cant remember
the model or type of engine apart from the mentioned.

I did drive a d21 with a z20 with cheap headers and although the head flows
worse than a v91 or 219 L head, it revved beautifully and had over 400k without
burning excessive oil or tiredness. I can only imagine how good those rods &
pistons would be in a fully counterweighed L20 with the right bits.

best sounding L ever from 8 min 50 seconds &n 9min30 pump up the volume!
