Think I have one local mate cheers does the 1.4 5 speed 1.7 5 speed and diffs match and can be fitted in any way ? What's the best way to do it do you have to do anything apart from switch across

Cheers mate

They are the ame but gear ratio' do vary. Make sure you get all the linkages etc.

So whats the best option heard from some people it stunts the power a lot with a 5 speed ?

I fitted a 1.7 5 speed M47R transaxle to my 1.4 1980 300 with the M45R about 20 years ago it is a direct swap , even the linkage fits , it cost me £5 ! The gear ratios of the gears are the same with 5th being an overdrive .

The final drive in the 343 was 3.9:1 , the one in the 1.7 is 3.64:1 so the gearing generaly was higher giving a relaxed drive at lower rpm with less torque of course , you dont have to use 5th gear but where you can it is worthwhile .

The final drive in your 1988 1.4 should be the same as the 1.7 ie 3.64:1 there will be a white label on the transaxle stating the final drive ratio .

Some data below .....

Thanks very much mate a brilliant help. Is there any way of releasing some power from the 1.4 engine jetting carb up or any tricks of the trade ?

Thanks very much

Regarding the 1.4 yes you can do a few things , i have an engine i rebuilt with parts from an old hemi head Renault Gordini 1400 , it produces 93 bhp with a lot more available with further work . Then there is the 1400 150 bhp Renault 5 turbo you could use this engine with some mods .This works fantasticly with the CVT transmission !
But to be realistic you would be better off fitting the standard 80 bhp 1.7 which goes very well and uses less fuel , again a bolt in job , but more road tax . A more modern and powerful Renault fuel injection version would fit too such as the range from the volvo 400 . .
