Subaru would have the right torque and powerband. Had a Turbo Subaru it was by far my favorite car to rip around in. How about a bmw m3 motor?

IIRC last time we measured a GM 3.8 V6 it was too long for the Lada's engine room and hence will require cutting to fit. Looking forward to seeing the end result; there'll no no shortage of torque at least Smile

Talk about engines, I would love to have a more reliable engine, a lighter one with the same or more power and fuel efficiency.

But so far all I read about is big V8's and Lancia Turbo, not some small japanese engine.
Any suggestions anyone on what might fit a Niva?

Properly maintained the Lada engine is a reliable as anything out there and a lot tougher.

True. But it depends on the ignition and intake set up, and to some extent one's definition of reliable.

Yes the basic engine is a good solid lump that will take much more abuse than most engines (and I've tested quite a few to their limits Smile ); but no points and carby car will be as reliable, powerful, and fuel efficiency as a good injected/electronic car in the daily grind.

Because Lada persisted with carby cars here long after most Jap cars were injected/electronic (and generally largely maintenance-free compared to Lada's '70s designs) people tend to compare the two, which I think is a bit unfair. It's not entirely comparing apples with apples.

Having said that, Ladas even in points/carby guise are quite reliable for points/carby cars (and a damn site better than some early and Euro electronic cars), though note GB's "with maintenance" caveat. And perhaps most importantly for Niva-ing I doubt any injected/electronic car will be as easy to fix in the field as a sensible points/carby car.



PS - AtrumMilitis, when you start your build thread it'd be great to place a link here.

The Fiat 1.9 turbo diesel engine is about 136kg.

That's the thing, you need to maintain them constantly.

I've had a Mazda 323 BG before and the only time it broke down was after I had burned the clutch out while racing it in the mountains. Apart from that had no problems whatsoever for 3 years.

To put it in perspective: it was a '91 mazda that I bought in 2006 and sold in 2009. The niva I recently bought is from 1994 and in good shape, yet I've had many problems.

Now I don't mind doing maintanance on a car, but I don't like to spend every weekend with my hands under the hood. That is why I would love to fit some modern, more reliable, lighter and more fuel efficient engine inside, something like that mazda engine for instance.

The other reason is that I want to use the niva to do safari tours with my hotel guests. I cannot do that if the car keeps breaking down.

I stand by what I said.

For a start any other engine is a compromise. It's not designed for the engine compartment and it's not designed for the drivetrain. You're going to have to fabricate custom parts to get it to fit and you will introduce more unreliability.

My Niva is a '96 and it has never let me down. It is the most reliable car I have ever owned bar none. Anything that has gone wrong has been my fault and my fault entirely whether that is lack of maintenance or asking the car to do extreme things.

If you're going to do safari tours I would stick with an engine you have half a chance of fixing by the side of the road with basic tools. The Lada engine that is.

While we're at it your ignition problems are almost certainly due to a worn distributor (lack of maintenance). A new dizzy will probably sort you out. I've no problem with electronic upgrades but it'll never work with a worn distributor. There is an electronic system you can get that just bypasses the points. The points remain in the distributor can be pressed into service in a minute or so if there is a problem with the electronic module.

For the money you would spend aquiring, fitting and fabricating the parts to fit an alternative engine you could get a new dizzy, replace the water pump, timing chain, tensioner, head gasket, oil, fluids and all the other parts of the Lada engine that might break and still have change for a few beers.

I know what I'd do.

yep,what gadget said,totally agree.

if you buy a car off someone whos never maintained it,you will always have problems.

ladas are very very reliable (unfortunately Embarassed ) and it's the owners that usually let them down.
