What diff fits E30?

What diff fits E30?

Most BMW E30 Differentials vary from 2.79 and up to 4.45. That means that the input shafts spin 2.79 times for each spin of the output shafts! With the transmission gear and vehicle’s speed being constant, the higher the differential ratio, the higher your engine will rev.

How do you find the diff ratio on a BMW?

Type bmw fans. And go to the parts catalog. So when you are here this is the the page that it will lead you to tell you which gear ratio exactly your bmw.

Can you put a V8 in a BMW E30?

BMW never put a V8 in the E30-generation 3-Series, but that hasn’t stopped owners from swapping in engines of their own. This car in particular has been treated to a new powertrain courtesy of a 5.0 Foxbody Mustang.

How do I know if my E30 has a limited slip?

Identification. To identify an LSD one can first check for the presence of the tag on the rear casing. The ratio on this will be prefixed with an S for LSDs. Alternatively one can jack up one rear wheel, ensure the car is out of gear and hand-brake is off then turn the raised wheel.

Can I put an e36 diff in an E30?

Yes that will fit. They are the same type 188 R&P.

Does Z3 diff fit E30?

The Z3 uses the same differential case as the E30, and is therefore a direct swap. This is especially convenient for the lower ratios Z3 diffs can offer; the 3.15 is a particularly popular unit.

How do I know my diff ratio?

Rotate the marked tire one revolution while counting how many times the driveshaft rotates. eg, If your driveshaft made 3 3/4 revolutions, that would determine a 3.73 gear ratio. If you get approximately 2 3/4 revolutions, you have a 2.76 gear ratio.

How do you calculate diff ratio?

How to Calculate Your Rear Gear Ratio Without Taking Anything Apart!!

What motor is in a BMW E30?

What engines can you put in a E36?

Here are the most common (and documented) engine swaps that people perform on the BMW E36 chassis:

• BMW S50 – 3.0 liter six cylinder from E36 M3 (240 hp / 225 lb/ft torque)
• BMW S52 – 3.2 liter six cylinder from E36 M3 (240 hp / 240 lb/ft torque)
• BMW S54 – 3.2 liter six cylinder from E46 M3 (333 hp / 262 lb/ft torque)

Can you do a burnout with a limited slip differential?

So going back to your question yes it is possible to perform a burnout with a limited slip differential and infect it would be a better burnout as both drive wheels would be getting equal amounts of power, it will prevent you spinning up just one single wheel and looking like an amateur.

Which is better limited slip or open differential?

If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD. When working properly, an open differential is the best riding, most comfortable option for everyday driving.

Are 3.73 or 4.10 gears better?

3.73 VS 4.10 Ratio

Does higher gear ratio mean faster?

Gear ratios can be boiled down to a single statement: Higher ratios (with a lower numerical value) give better torque/acceleration and lower ratios allow for higher top speeds and better fuel economy. Higher ratios mean the engine has to run faster to achieve a given speed.

What is the formula for gear ratio?

The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).

What makes the BMW E30 so special?

Its boxy wedge design that was an overarching theme throughout the automotive industry in the 80s is one of the few that many consider timeless. As is the case for most cars made in this era, it had the customary explosion of buttons, but everything else in the interior was pure class with only premium materials used.

Which E30 is most reliable?

“The S14 is probably the most durable and reliable of the E30 motors. If it’s had high quality maintenance from a diligent owner, is easily a 300,000-mile drivetrain.

Can I put a v8 in a E36?

E36 V8 swap – THE ENGINE IS IN – YouTube

Will a M54 fit in a E36?

Physically fitting the M54 in the E36 is very easy. An M54 from a Z3 will bolt into an E36 as-is. An E39 M54 engine will need engine mounts swapped to E36 mounts – the E39 oil pan fits on the E36 subframe (I am using an E39 engine with E39 oil pan).

What differential is best for racing?

Limited slip differential

Limited slip differential
As we saw, both a spool and an open diff have their issues, especially in racing conditions. Most race cars thus use a limited slip differential, which offers the best of both worlds.

Do both wheels spin with limited slip?

The easiest way to tell if you have an open differential is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.

Why do people weld their diffs?

The most common pros of welding a diff is keeping both the back wheels on the car spinning faster than the inner wheel in a turn or corner. As you know, keeping both the wheels spinning at the same rate will cause the inner wheel to lo0se traction and skip, making oversteer easier to accomplish.

Are 410 gears good for highway?

Installing 4.10 gears improves the car’s performance on the track but with negligible effects to the highway driving. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing.

What gear ratio is the fastest?

In the real world, typical street machines with aspirations for good dragstrip performance generally run quickest with 4.10:1 gears.

What gear ratio is better for torque?

The numerically higher gear ratio (in this case, 4.30) increases wheel torque and improves acceleration from low speeds. But the engine does have to run faster to achieve a given speed.
