Gearbox of ClioII

[clio_manu]

Hii im new at the forum, Im Manuel from Venezula and i have a clioII 1.6 16V. My question is: can i replace the 1.6l 16V gear box with the 1.4l 16V gearbox???, is the same???, what are the specifications of the 1.4l 16V gearbox???, all i know is that the 1.4 gear box is shorter.

And im going to increase the compresion on my engine, whats the most recomended compresion that i can have on my engine???.

Thanks for all you answers.

they are the same gearbox from what i know...

1.4 16v uses the JB1 box whereas the 1.6 16v uses the JB3 box, obviously better torque rating on the JB3 box. If/how long the JB1 would last pass, in relation to the ratio difference it isn't worth doing.

So you are saying that if i replace my gearbox with the 1.4 16V gearbox there isnt going to be a change in acceleration or in 1/4 mille time???.

 

[Fred@BTM]

nope

 

[clio_manu]

Ok, but the 1.4 16V gearbox is shorter than the 1.6 16V gearbox because i drived a 1.4 and the gears was shorter than in my car, so if is shorter i would have more torque at the wheels in my car, thanks for your help.

the 1.6 bx is the better one out the lot. i had a 1.4 box on my 2.0 and it slowed it down.

 

[clio_manu]

My clio is a 1.6l so you are saying that it would slow down my clio like your 2.0 clio if i get the 1.4 box??.

It won't slow the car it just chnages the speed in gear.

there are clios in venezuela too?

 

[clio_manu]

Yeap there are clios in venezuela, and im working on my clio to do 1/4 mile, so im asking here if can i change my 1.6 gearbox with the 1.4 gearbox to obtain more acceleration???, do i have to do other modifications to change the gearbox???, or are they the same??, thanks.

As you've already been told it won't make any difference.

As far as I know our JB gearboxes have a slightly different ratios than the european Clios, that due to the different roads setups...ours are slightly shorter. I've been told that the JB3 and JB1 are almost identical with a small difference in the last gear...

You can also use the 5th gear found in the JB3 used in the Megane Classic for a longer 5th gear ratio....better fuel consumption and slightly better top speed, dunno how much.
