TDi 5th gear.

[ScienceVR6]

I was just thinking tonight. Could i fit the 5th gear from a TDi into my VR6, and take advantage of the taller ratio, maybe i could improve my fuel economy. would this work? has anyone ever done it?

Not to my knowledge. Be a pioneer

they do it all the time in the US but usually after changing their final drive so theyre not doing 3000rpm on the fwy.
Its not a cheap part though. Last time i checked was around $250US plus shipping.

I always found it a little odd that my vr6 does 3k rpm at 100kph, I expected less. My old 1986 Mazda 626 did the same revs at 100, but with a 2L 4cyl carbie motor!

Does seem odd seing as the VR6 does 160 in third.

I think its so u can put the power down easily without having to downshift?? It really annoy me tho and one of the downsides to my car. Lucky i dont have an exhaust to exacerbate it!!

Dude, a VR6 without a decent exhaust is like...

...heavy metal without double bass drums!
...violent computer games without oceans of blood!
...nandos without extra hot sauce!

etc

My exhaust really drones at about 80, at 110 it's pretty quiet.

Except when my ears are bleeding at 90. I think I'm going to try some exhaust wrap on the straight sections, see if it cuts down on some of the resonance.

vr6 does 100km at about 2650rpm with stock gearing

my CL does 108 exactly at 3000rpm

does this seem odd to anyone other than me? especially when there is a 1000cc difference to a VR6!!!

I'm going to have to check this but my gearing if in 5th gear is just under 3000rpms at 100kph I think!

Also mine goes both up exactly the same time in fifth gear

[MattyT]

Nup, mines at 3000 in 5th at 100. Dont know what your 2500rpm thing is about??

[bboyskidz]

geez guys that means a heck of a lot of fuel...

[MattyT]

Indeed

Oh and my old exhaust used to drone baaaaaaaadly at 90 or 110, but at 100 it was perfect.
Found out it was a straight-through system though, so thats probably why!
Ditched the rear "muffler" for an actual muffler and the drone is all gone.
