Is there a jc5 gearbox ratio list/ graph anywhere ?

[ginge!]

I have a phase 1 Clio 172 that now needs a gearbox so I wish for a taller or longer ratio box in general but not sure where to look ect for info

Anyone have recommend places to look for charts or even what other renault to look at nicking a box out of

 

[Jaff.]

try a google search, i found a PDF online before with all gear ratios for jb3 and jc5's

 

[ginge!]

Can't find a working PDF but does anyone know if a jc5-128 box would work in a ph1 Clio with the speedo ?

 

[tom172cup]

I thought the ph1 box had the longer ratios. Failing that fit a Dci box

 

[marinemackay2003]

Dci 100 gearbox has longer ratios iirc and is a straight fit

You can also remove 5th from your box and put a different one on from a jc varient box

 

[ginge!]

What dci box can I uuse in a phase 1 clio as I read about speed sensor rear issue ?

 

[marinemackay2003]

The ecu can be plugged in via Renault clip, then be made to take the Reading from your abs system

Just leave the sensor in the box

May be worth speaking to Renault or some of the specialists on here

 

[tom172cup]

How come your after longer ratios. What spec is your car. And there not amazingly stable at 150

 

[marinemackay2003]

What can you top out at tom?

I'm building a boost bus too

 

[tom172cup]

On the speedo just over 150. With more revs left to go I would love to hit the limiter and find out what the actual box will do top end. It's hopefully going to get the vag box at some point so I presume I shall be going quicker top end

 

[marinemackay2003]

Same looking at the vw box conversion, but will wait out a bit and see cost ect

your looking at about £1200 mate

 

[marinemackay2003]

Cool not to bad then, need to buy my supercharger first though

 

[Jaff.]

lol the thought isnt bad but when you see that money leave your bank account you do die a little inside!

 

[marinemackay2003]

Good job the other half can't see the moneys spent LOL

 

[tom172cup]

your looking at about £1200 mate

Is that DIY.

 

[Jaff.]

yeah, althoughy i think scoff is looking at doing a drive in drive out conversion, no idea on price but i should imagine him doing it for roughly the same price

the flywheel costs £450 by itself, buy a box, clutch, adaptor plate, custom mounts, driveshafts, clutch master cylinder and resevoir all adds up.

ive spent £750 so far and i have the adaptor plate, engine mount, flywheel, clutch and master cylinder.

resevoir is only £10 but driveshafts will be a pretty penny and i had the box for free so its not cheap

I hit 160 :O

Friend was doing 155 in his Evo and I came past! Felt stable!

I don't currently have a working speedo at the moment, I do 5000 to 6000 rpm in 5th driving to work which kills fuel and I do 400 miles a week at the min too

I don't currently have a working speedo at the moment, I do 5000 to 6000 rpm in 5th driving to work which kills fuel and I do 400 miles a week at the min too

so your doing 100ish mph for 400ish miles a week... theres your fuel problem

 

[ginge!]

Ps top speed and driving very fast it what my impreza is for

The idea is I rebuild a this current box in time with just a longer 5th when I learn more options for it but need the ad as daily runner is more important

 

[ginge!]

Hence longer box option for me as I don't live near work and. My little free time is precious due to commute I do

 

[Jaff.]

how about reducing your speed to 70 and save yourself a fortune?

4-4.5k should do it

 

[ginge!]

I'm more thinking longer 5th gear and sit at 3800 to 4300 and save fuel, thinking of saving the trees and antarctic blah blah

4k I'm my impress is just over 100mph and works well on motorways though crap playing

 

[Jaff.]

so youd rather change the box than lift your foot half an inch?

 

[ginge!]

So what gearbox code ami looking at ?

 

[ginge!]

I'm happy with the speed I'm doing vs time traveled, i could reduce the speed to 3500 and part throttle and have 45mpg with closed loop but I like leave later for work Nd get home in time for dinner

 

[DannyR]

So your openly admitting you sit at 100mph all the time on the motorway?

 

[ginge!]

Not on English roads obv as that is not legal but when I drive through parts of Germany ect when I drive to Maastricht and kellberg and adenau oh and nurburg

 

[ginge!]

Now, a box code is More is use than legal advice for me as I have a 172 with a fucked box and already have a member of family who is a magistrate lol

 

[DannyR]

So you drive through Germany everyday and get home in time for your dinner?

 

[ginge!]

Not everyday Just enough to think of this option, I don't know the speed I'm currently doing as my speedo does not work but I'm going with the flow of traffic to gauge a fair assumption of speed, when the new bixgoes in and I have a speedo it's clear I won't break the law but I need a gearbox code to do that hence the point of my post, not willy waving about breaking the law, I'm 32 years old not 19 and thought this site would be a good reference for clio advice, wonder in the law forums could give me car advice and a gearbox code when I ask for legal help perhaps ???

lol i dont care if you speed, but its affecting your economy... the diffrences in gearbox codes and 5th gear ratios are going to be negligable anyway if your traveling at that speed evrywhere.
jc5-128 is afaik one of the longer ratioed boxes off a clio diesel

 

[ginge!]

When I changed my box on the impress to a lOnger box I noticed straight away the difference in fuel economy but that box was stupid high for the wheels and diff that you can't do 4th round town so sort of hoping the a little extra might help even if it shuts the car up as my exhaust is drony when it's over 4krpm( notice I don't mention what gear or if it's past old people's homes near schools at 15:30 or if I'm driving through foxhole at the ring or even playing a character in grand theft auto and car jacking a Clio 172 of some pimp then off to murder a hoe )

Maybe it's the roads I'm doing that on. It has more to go but that's not far off I shall leave the big speeds to my latest purchase

 

[DannyR]

I mananged to do it within less than a mile, probably 1/2-3/4 a mile

 

[tom172cup]

Yeah this was around that distance if not a bit more but yours was proper stripped out. Vag box and 50 hp of gas should sory it out

 

[DannyR]

That is true, it weighed f**k all lol!

 

[tom172cup]

That is true, it weighed f**k all lol!

And it was a phase one

 

[sammyhale22]

You guys on here getting 150-160mph from the 172, how is that possible? I`ve had close to 140 tops from my 172 cup and thats getting to the red in 5th...
