zolorin Posted September 28, 2003 Share Posted September 28, 2003 hey people, I just got lucky by finding myself a diesel maxima crank for my 3.0 TS engine build up. but the question arises what is the benefit of the 240Z rods vs. 280Z rods: from my understanding the 240Z rods provide a better ratio of rod length to stroke, but what is the ideal and WHY , I want to understand the priciples thank you all Quote Link to comment Share on other sites More sharing options...
Guest norm[T12SDSUD] Posted September 28, 2003 Share Posted September 28, 2003 The 240Z rods are the right length for the 240SX pistons you need to make a 3.1 Stroker. You can use the 280Z rods and 280Z pistons as I have done in my 2.9L stroker, but you need to shave the pistons .015" and use two stock headgaskets or shave ithe pistons .035" and use a 2mm HKS headgasket in order to keep the the pistons and head from colliding. Also, the longer rods contribute to less side loading and increase HP due to the longer dwell time at top dead center. However the shorter rods improve lower rpm range torque.
