Best LSD for a turbocharged a10?

I have looked around and I really want to switch the stock diff out of my 78 datsun 510 (a10). I have seen some other sites talking about it but it was for the first gen of the 510 and I wasn't sure if they would match an a10. I'm planing to keep the l20b and turbocharge it. I may also switch the transmission out for a 5 speed. What LSD will handle the power and torque and will fit my a10 the best?

The A10 had a solid H-165-B rear axle containing the gears. The H in the H-165 refers to the solid axle tubes and removable third member. The 165 is the diameter of the ring or crown gear in mm (about 6.5") and is a fairly good indicator of it's strength. The B (I'm not sure) has something to do with the carrier material used in the third member. The H-165 will handle 225 ft lbs of torque or about the maximum a stock L20B with 4 speed will put out.

 

A10s with L20B manual and automatic were 3.545 ratio. All Z20S engines were 3.364

 

All sedan A10s were 4 link and coil suspension. Wagons were twin leaf spring.

 

 

The earlier PL510 came with an R-160 (6.3") independent rear suspension (IRS) and also come with a solid axle H-190 (7.5") The H-190 can handle about 285 ft lbs of torque.

 

By handling the torque I don't mean 7K clutch dumps and 30 feet of one wheel tire hopping.

 

 

 

If you want an instant kick in the ass performance up-grade get the H-165 third member from an S10 (the early 200sx) and swap it. The S-10 used a 3.889 ratio for a 9.7% increase in RPMs. Fast and easy and no mods whatever to the engine.

 

You want stronger get the rear axle from an '82-'83 S110 (second gen 200sx) they were H-190 and similar width. A bonus is the rear disc brakes and it's already four link and coil suspension. With the H-190 you have choices of gears from 3.545, 3.70, 3.889, 4.10, 4.375, 4.625 and 4.875.

 

LSD??? you don't need it.

Jesus Christ.

A 605 is a massive hemi engine. When stock it can make about 1000 hp.

Engine is running like a champ with help from you all and my book.

The engine as of right now does not have a turbo but is finished.

The brakes I have can stop the car and that's ok with me for now.

When I try to race people the one wheel will spen and the other rear one will sit. This is why I'm asking for an LSD. I'm sick of not getting off the line first because of it.

I'll post a video of it driving soon.

 

All races are legal.

Because it has  to have a little fun. No. The 605 will kill me. I'm crazy not stupid. Plus that's going in my 68 charger. Datsuns are fun to drive. My 510 likes going around runs sideways. My charger is too easy to get sideways. And my car has a bitchy personally. To me a car with a bitchy personality is better then a car that is reliable.

Find a '74 710 automatic. It'll have the L18 engine. It has a 4.11 H-165B in it. You won't need to rev the shit out of the L20B and side step the clutch when racing. Just drive off smartly and those gears will pull your head into the back seat. Four elevens are a 16% increase in RPMs in all gears.
