I don't think you need to do much with the timing.

The 4d55t has a compression ratio of 21:1 and the 4d56t is around 17:1, and after listening to it run I wouldn't touch it at all. It sounds fantastic!

Congrats on getting it to work, and welcome to the forum!

as far i can tell its scaring the heck out high 20`s to low 30`s... but there has got to be room for improvement!!

the darn speedo it out 5mph...so if you are doing 55mph your really doing 60...!! the G54B & 4d55t are really the same damn block!! the G54B gas engine was 4d55t diesel converted to a gas engine!!!

"Mazda built the Mazda B2600 for several years. During two of those years ('87-'88), the carburated engine blocks were the 2.6L G54B! The other "2.6" engine produced during this time was called the G6. This is also known as the MPV block.The RX7 transmission WILL NOT bolt to any 4G6x engine. You will need a B2600 bellhousing to adapt it to the Mitsubishi wideblock. It is also possible to bolt the B2600 transmission up, but it may have a longer input shaft which will not work with the Starion flywheel."

tranny info i used was here!!

http://idahoturbodiesels.com/vb/showthread.php?t=11383

and another white b2600 4d55t conversion (that i didn`t do the swap on ..i bought here this winter in alberta...as part of the deal it also came with the red d50 4x4 parts truck) the b2600 4d55t conversion truck its bottom end making noises.... thats 3 (i think you might see it in the build thread.. its got a black hood).. hey thats good name for this truck the black hood!!! :-)

This is awesome: I hope you get to keep this one!!

(Want to build another after this one? I sure could use one!)

i tell ya i soon as get any one of these fixed up i hardly ever see the damn thing ....its gone!!!!...i guess cheap transportation never goes out of style!!

the grey one has put on 40 thousand miles here in 2 years (timing belt change in 18 months ...got to be a record)!!....And finally the nephew got a hold of his own d50 4x4 4d55t.... had to drive 8 hours nw of here to go & get it!! :-)
