olddude Posted August 29, 2006 Share Posted August 29, 2006 Has anyone tried to upgade the 3.0L engine to a 3.4L? If so what is involved? Will the stock computer work? Is the auto tranny the same? Thanks Quote Link to comment Share on other sites More sharing options...
bufbooth Posted October 7, 2006 Share Posted October 7, 2006 Has anyone tried to upgade the 3.0L engine to a 3.4L? If so what is involved? Will the stock computer work? Is the auto tranny the same? Thanks I never saw this done on a toyota motorhome, but I saw a Chevy 350 V* installed in 85 Toyota pickup truck that had the 2.4 engine in it, and was actually a nice fit. There is a CA company that sells the needed motor mounts and the transmission adaptor. Quote Link to comment Share on other sites More sharing options...
Bunneys Posted June 6, 2007 Share Posted June 6, 2007 This Swap looks to be an easy option! You will need the ECU for the 5VZ-FE but most of the 3VZ stuff will/can go onto the 5VZ and it all bolts together! The hard part is exhaust... Lots of links available on this swap, One of the closest I could find on a 1991 Two Wheel Drive X-cab.... http://www.automotivetalk.net/showmessages.php?id=633 Some more: http://www.yotatech.com/showthread.php?t=69448 http://www.yotatech.com/showthread.php?t=82145 http://www.yotatech.com/showthread.php?t=50550 http://www.4x4wire.com/forums/showflat.php...part=1&vc=1 http://www.offroadsolutions.com/technicala...version_kit.htm http://bb.bc4x4.com/showthread.php?t=21569...ight=5vzfe+swap Quote Link to comment Share on other sites More sharing options...
