MOTOR SWAP Q.

tydaug · Post by **tydaug** » Mon Aug 10, 2009 1:01 pm

My 2.9 is knocking pretty bad more often than not and instead of rebuilding it, I want to put a 4.0 in it. I found a grea deal on a 92' mazda navajo but it has an auto trans. Ignore wiring setups....I want to know mechanically what to do .

.. thanks

the 4.0 will bolt to your tranny.take the clutch setup off the 2.9 and swap it to the 4.0. save the 4.0 Y pipe

Well I already have a tranny from a 4.0 on the truck now. and know they will bolt together. i just need to replace the torque converter with the clutch disc/pressure plate. both motors use the same flywheel?
