Hi all. Bought another niva yesterday and i want to make it rwd. My sister wants the thing and it wil NEVER go offroad. My only problem is the speedo. Can a plan be made to put it in the gearbox? Looks like there is a place on the box for one. Can one get something like this? Regards Ruan Attachments:

;)On that model you can pick up speed directly off the front wheel!! Why convert. Just take the low rangelever and diff lock lvers off, put a cover over the tunnel and you sister will be happy with excellent road holding in wet weather Spikes

You could order the parts from a Niva 2105 or similar. A old fiat speedo drive and gear will also work.
But I agree with Spikes. Keep it 4wd. Handles alot better and it isnt any heavyer on the fuel. Also the diffs are not designed to have just one working. t gets overworked and can get damaged.

Hi roons, I have to agree with Spikes and Charles about the handling, but why bother taking the (not used) gearlevers off ? They really don't get in the way......and what if you need to 'borrow' her Niva one day for some of your offroading fun :-) Regards to all at LOCSA, Keith and CERATOTH

i agree with the rest of the crew here, but i will give you an answer to your question. It is possible to provide the Niva gear box with a speedo drive. As it so happens today i will take apart a gear box with the speedo meter drive inside it. I will take pictures and post them later today. But remember: you will have to take the gear box apart to put a drive in it.

I hear u. What i want to do is to take the front diff, transfer case etc off and make a new propshaft to the rear diff. Mainly i want to steal some parts for my lada. But it wil be a bit of a shame.

Jan please tell us. Charles when you remove the TC, the final drive changes a lot (to much). The TC's high gear ratio is 1,2
gear box and rear diff are the same as a Lada saloon 2x4, but the saloon has 13 inch tires and the Niva 16 inch. That's why Lada builded a lower gear ratio in the TC differential. This has nothing to do with high or low gear. Or: your Niva will have a very bad acceleration, but will have a theoretical top speed of 180 or so. What he will never reach because of serious lak of power now the pics: a normal Niva gear box looks like this. At the end of the output shaft sits a spacer The gear box of a Lada saloon looks like this: at the end of the output shaft sits a gear. Both parts are interchangeable, but the fifth gear housing must come of. This is the outside of a normal Niva 5 gear box: there is a whole in the material of the housing. You just have to pop out the stop and attach this to the gear box:

Charles. I built the bmx for my brother. He then almost killed himself with it. Its a nice toy and also works for transport. It wil go 100km on that 2l tank.

I recently spoke to a local owner who is currently converting his Lada to 2WD, and he is installing a Nissan 1400 engine to his Lada ... Danie

I think if he could get his hands on a L16 engine it will be a fun car.

This is a bit of the topic but i spoke to Kobus at eezy cars (lexus v8 guru) in centurion and he said he puts 2li colt engines into the niva and keeps it 4x4. He makes adaptors flywheels etc in his workshop looked like he knows his story. Maybe i must try it and see how and if it works. He can also make adaptors to fit vw motors. 2l 8v has verry nice torque, my golf had 188 nm and 75 kw atw.

Jan. Ja as shure as a number on a paper so no. But it had some small mods like ported, management, branches, and the motor was rebuilt. So it had oversize pistons. The tuner told me he can get 90kw at the wheels. Just ended up with standard power but more torque. Max kw was under 5000revs.

Jan I do not agree with you about the tc high ratio. That means that with a 4.1 ratio diff in 4th gear at 120km/h you would only be doing about 2000rpm. The low ratio on the tc is 2:1. The high is 1:1.

Charles, from the 1700 manual: this ratio has nothing to do with the gear box or front and rear diff ratios
|
|
|
Post by Charles on Apr 6, 2012 16:06:31 GMT 2
The top ratio is not 1 to 2 it is 1.2 to one. For every 1.2 turns of the tc input shaft the output turns 1. High ratio is 1.2 to 1 and low ratio is 2.135 to 1.
So without the tc your ratio's will be a little bit longer.

Charles i agree. Took the TC out and it looks like the gearbox turns 1.2 times for 1 turn on the flange going to the diff. Maybe if i put the tyres from my lada (small rally 15s) it wil work. Im repairing the geabox and if there is any problem with the 4x4 im going rwd.

Sorry Jan i read it wrong. My apologies. Not trying to start a fight. With such a small change in the ratio I do not think it will make a huge difference. Especially with 195/65R15 tyres.

Charles, 1,2 compared to 1 gives a 20% difference. I would give an arm and a leg (from some one else ;D) for 10/43 diffs. I have 10/41 diffs now, so it would give me a +- 5% shorter diff. Believe me: it's a huge difference, even that 5%

Post by Charles on Apr 7, 2012 11:48:20 GMT 2
Thanks Jan. Why did you go with longer ratio diffs? Would the shorter diff not be better offroad?
