Lets talk Manual gear ratios

[SiliconAngel]

But you're not gonna put it in when you have the tranny out??

 

[bradc]

Nahh the current exedy is doing it's job fine, so why bother changing?

 

[bonecracker]

changed my diff on my r32 25det from 4.3 to 3.5 made no difference in fuel economy just less engine noise.

 

[timmae2006]

Any thing new on the new gearsets anybody has put in?? "digging up an old and forgotten thread"

 

[bradc]

I've had the 2.928, 1.950, 1.407, 1.031, 0.721 gearset in my car since the end of 2008 as the thread above alludes to. Here is the thread posted on cvr4 http://www.clubvr4.com/forum/showthread.php?t=36411&highlight=gear+ratios+thoughts


My only complaint about the longer 5th is that my exhaust drones a bit at 2500rpm which used to have disappeared at 110kmh but now at 110kmh I can hear the exhaust a bit. Annoyingly at 120kmh it is silent and stays silent when cruising at speeds of up to 180kmh.

 

[YTRY50]

so in a typical 50kmph street speed zone you would reconmend 4th or 5th ?

 

[bradc]

If you're actually doing 50kmh, I'd be in 4th.

 

[timmae2006]

Is it a hard task to change 1st and 2nd gearsets over to the longer ratios?

 

[bradc]

It is a full gearbox out job, so you can't do it in an hour or two!

 

[timmae2006]

Lol yeah i know i realise that and a good thing the whole engine is coming out next week too, so once the box is out is it pretty straight forward? and who else apart from ivan can supply the 1st,and 2nd gear sets? hes not replying to me

 

[bradc]

Yeah if the box is out it is very easy.

 

[Kenneth]

Make sure you carefully remove the bearing races and make sure you know which went where and which preload spacer is from which. This is very important.

In all honesty you should probably change the bearings while you have it apart, just make sure all the preloads are re-done.

 

[timmae2006]

Riiiiiiiight, I need to source the gearsets first, cant find any

Let me know where you get yours from I'm interested too

 

[timmae2006]

BAHAHA i think you may find some before I do if your looking.......... ive got other priorities like rear turbo , ive asked a few times where i can source the gearsets from but i never got any assistance, maybe if you find out you can help me out too as i think my box is coming close for a bearing overhaul and would like to swap gearsets same time obviously

Thread digging here as something has come to my attention.
If evo gears fit do you guys think these will?

There are also sets for 1-3 evos which I believe is the same bell housings.

 

[Macca]

Holy S**T those parts are expensive.

PPG dont have synchros; not as good for daily.

Check to see if par-engineering could help I hear they do straight cut synchros for the evo. also sheptrans but I think they are mainly drag. I have no idea of price on either of these.

 

[unclepaulie]

the rest of your car will fall to peices before that breaks.

actually the 'koval' evo ended up blowing a peice of its gearbox casing apart cause the gears didnt give lol

Yes they do, they provide either synchro engagement or dog engagement.
