Manual Gear Box VR-4 Owners - Do you feel the gearing is too short?

[bradc]

hah lol. It should be possible to get an EVO 8/9 6 speed gearbox into the car. I looked into it a while ago, the evo transfer case and ACD system will need to go in as well to bolt up to the gearbox, and obviously a custom bellhouse will be needed as well.

I do think that for most people a change to the 3.73 final drive available from TRE is the best bet, it takes 2nd gear above 100kmh, you will never need to change out of 4th when going down the quarter mile, and 5th gear is usefully lower for cruising.

[Gowf]

No thats what i was thinking, but then im also looking for straight cut 1st to 4th with helical 5th. even that though is going to cost a small fortune!

Thats their website, they do lots of work with strengthened evo gearboxes, and they will sell you the final drive seperately.

Expensive but interesting

Apex performance are selling gearsets from PPG Australia, so available UK and Aus.

Speaking of final drives, have you managed to source one for your purple beast yet?

[bradc]

I will get one from teamrip, just need to get the money

Thread revival.

Just to let everyone know that the Evo gearset we put into the Galant works very well.

Just to recap, the gear ratios (standard final drive) are as follows

2.928
1.950
1.407
1.031
0.721

vs stock

3.333
2.105
1.407
1.031
0.761

With the correct wheel and tyre combo (i.e. to correct the speedo) this allows 60mph/100kph in 2nd gear by 7000RPM.

The longer 1st makes a huge difference. It actually feels like it is doing some useful acceleration without just being a means to reach 2nd.

Longer 5th didn't seem to make a great deal of difference apart from a drop in acceleration ability, though I wasn't maxing out 4th before changing. Unless you find you often run out of RPM in 5th, I wouldn't be concerned with the longer 5th.

Obviously everyone has a different driving style, I like to keep RPM around 3000 anyway, so this gear set is pretty good for me.
This being the case, I am less inclined to be interested in a final drive swap as I don't like the idea of shifting the 3rd and 4th gear ratios from where I use them now (cruising at town speeds).

The only down side is that a bit of extra urgency in 2nd means that I keep getting to the speed limit (not exceeding of course) around 4000RPM and not feeling satisfied!
Oh, and I don't think the AYC diff likes 1st... ANY sort of launch automatically puts up 3 bars.

Nahh what you have is:

2.928
1.950
1.407
1.031
0.721

The first set you posted with 2.785 is the one I have in my wardrobe, and the 3.333 is the stock VR-4 set

lol, copy and paste error! Fixed.

You are welcome to give your thoughts on the gearbox too... be interested to hear you thought on driving it.

[OnBoost!]

Yeah i thought that when i took it on the motorway for the first time,sits at about 2000rpm at 80kms.

[bradc]

The longer 1st and 2nd gears are basically perfect, 1st gear is still over really quickly, and it shifts into higher rpm in 3rd as well meaning that the first 3 gears are much better to drive with.

[zentac]

whats the final drive ratio on the 2 boxes? I kept the same gear ratio's on mine but changed the final drive ratio to make them all that bit longer. Im now having a dog box designed with a very long 1st for drag racing but the optimum gear ratios changed depending on the amount of power you have. So whats optimum for my 500bhp FTO wouldnt be any good (well wouldnt be optimum) on a 700bhp FTO.

[bradc]

Both are 4.111.

What ratios are you running exactly?

Brad - I got some info on this last week that is potentially useful.

I have been told that the Airtrek Turbo has a transfer box without the ACD that mates to the 6 speed box. The guys I spoke to seemed to think that you could put that in to a VR4 relatively easily.

All we need now is someone with too much time and money on their hands to give it a go!

[bradc]

Interesting, would make sense because they have the same engine, but I thought they all had 4 speed auto's?

[Nick Mann]

I have absolutely zero experience of Airtrek Turbos. (Except a spirited drive with one in close proximity a couple of years back!) The info above was given to me by a chap who works at Xtreme - formerly Ralliart UK. I can't vouch for the accuracy of his info, or for what he thinks counts as relatively easy, but I though it was well worth mentioning.
