Are you not worried the car will feel less quick in acceleration Daz?

Not at all because it will still be quicker than yours ??

Will mapping need to be tweaked ?

Daz I heard you mention that a breaker had a 3.23 diff how much did they want for it and was it a BTR ?

About 400

If anyone has a GKN diff or just unwanted innards either 3.45 or better still 3.77 I am happy to buy them or I can swap units for a spare higher ration 3.31 GKN that is sitting on the floor in my garage. Cheers Jes

I must say to chimpongas that the combo of turbo and 3.08 diff is just perfect. 2. and 3. gears are monster gears now!!

[ClassiChimi]

I'm pretty sure mines a 3.08
Using a sat nav on my phone so hardly scientific but I recorded

Speed mph Gear. Revs on counter
50. 5th 1625
60. 2000
70. 2390
80. 2790
90. 3200
100. 3400

30mph 4th gear = 1200 revs.

As can be seen by these results the sat nav for speed reading is a bit hit and miss,
But that's close to COG calc for 80mph so as I thought I have the 3.08,,, needs to be higher geared still,
That's why my fuel economy figures are pretty good too, 30 mpg on a run easily.

You'll love the difference Daz.

Mine is 3200 at 90 as well. 1999 car

[ClassiChimi]

That's good then Mat, and it's true to say 2nd and 3rd gears are mega with this gearing.

[TV8]

Mine is revving a bit higher at 80 - 3000 revs http://www.pistonheads.com/gassing/topic.asp?h=0&a...

Lots of other cars are similar. S reg, not sure what the year is!

I am running pure NA Daz.

On the gearing front my car has a 3.08:1 diff and with 245/35/18s does 90 mph at just under 3000 rpm

Hi Darren,

Yes this gear set will fit if you want taller gearing, Will also need new pinion nut as well new gear set have 22mm pinion thread size now don't know what size TVR have may still have smaller thread on pinion

Thanks Diff Trans
