Llittle_Llama Posted September 19, 2008 Author Report Share Posted September 19, 2008 pretty much what i was thinking, so what am i looking at really? should i go with a 510 rear? will that fit better? i will measure my 240 rear tonight adn post up tomorrow. Quote Link to comment
fisch Posted September 19, 2008 Report Share Posted September 19, 2008 I have no idea! But I've been itching to see someone do it, go for it! Quote Link to comment
Llittle_Llama Posted September 19, 2008 Author Report Share Posted September 19, 2008 i was hoping on the 350z rear, but money is kinda tight with all the shit i have going on really.....going to afghanistan in january, trying to buy a house, finishing the rb in the 240. plus i just bought a new mac to take to afghanistan and that was 1700....

slodat Posted September 20, 2008 Report Share Posted September 20, 2008 dwnshfter, are you serious or are you making contemplative conversation? If you don't have the fabrication skills & tools and engineering ability, you should stick with the H190 in the truck. It can handle the power you are "suggesting".. Quote Link to comment
datzenmike Posted September 20, 2008 Report Share Posted September 20, 2008 A solid axle would be better for drifting. You definitely want LSD in it too. Here's an idea... Look through the VG powered Pathfinders for one with the Sport Package. Factory LSDs were optional on them. Find one and get the diff. and the axles with backing plates for the rear disc brakes. Next get the rear axle housing from a VG powered D21 Hardbody and fit the H-233-B differential and axles into it. You now have a much stouter H-233 LSD differential with disc brakes. You could jusrt use the Pathfinder axle complete but they were coil spring. These would need cutting off and the spring perches welded on. Quote Link to comment
Llittle_Llama Posted September 20, 2008 Author Report Share Posted September 20, 2008 hmmmm, tat sounds pretty good too, much better than what i was thinking. only reason i was thinking 240 was to make it easy. i will not be doing the fabbing, there are a few nissan guys around here that wanna do the swap and they will do it all, i will just assist. i was really wanting to get away from the 6 lug though and was another reason for the 240 rear end.

Bleach Posted September 20, 2008 Report Share Posted September 20, 2008 whatever you do, do not put a 510 rear in there. They are weaker than what you have. Keep the stock rear but buy an LSD for it. And if you're trying to keep costs down why would you suggest a 350Z? Did you steal one? Quote Link to comment
moparvwfreak Posted September 20, 2008 Report Share Posted September 20, 2008 Look through the VG powered Pathfinders for one with the Sport Package. Factory LSDs were optional on them. yup! i have one in my 95 Pathy SE Quote Link to comment
Jester Posted September 21, 2008 Report Share Posted September 21, 2008 Curious. What is the differance in width between the 620 housing and the Pathy/HB housing? Personally, I'm not concerned with what type of mounting each has. I can take care of that. How about available gear ratios? Quote Link to comment
Llittle_Llama Posted September 21, 2008 Author Report Share Posted September 21, 2008 And if you're trying to keep costs down why would you suggest a 350Z? Did you steal one? no, just a lot of 240 guys swap them in..... Quote Link to comment
Llittle_Llama Posted September 21, 2008 Author Report Share Posted September 21, 2008 there is a 620 about 100 miles from here for 500. i am going to get it this week hopefully. i will continue the grave datsun on its path to the weeds, and the new one will be getting the dohc swap and will become this project. more updates soon........

I have an '82 axle in my 620 so I don't know how wide they(620s) are. The two Paths near me are 4.375 and 4.625 non posi I think. One has the rear disc brakes... kool! Quote Link to comment

nismopu Posted September 21, 2008 Report Share Posted September 21, 2008 pathy rear end is 5/8" wider than a HB rear end which is quite a bit longer than a 620 rear end. Also, most v6 pickups built after 4/87 came with an LSD anyway so you wouldn't need to find one from a pathy if you find a v6 pickup. Shortening an axle could be quite cost effective though if you find the right places to do it. peace. Quote Link to comment

]2eDeYe Posted September 21, 2008 Report Share Posted September 21, 2008 Are the axle splines bigger/different count on the Pardbody/Pathfinder compared to the H190? Quote Link to comment
Llittle_Llama Posted September 22, 2008 Author Report Share Posted September 22, 2008 ok, looks like were gunna shoot for the stock rear end for now..... still would like to think about some of these options though, so lets figure this stuff out!:thumbsup: Quote Link to comment
datzenmike Posted September 22, 2008 Report Share Posted September 22, 2008 2eDeYe;82448'']Are the axle splines bigger/different count on the Pardbody/Pathfinder compared to the H190? I know what you're thinking. I asked on another forum. The real question is will they, and the wheel bearing, fit the 620 axle tube? Quote Link to comment
cgovia Posted September 22, 2008 Report Share Posted September 22, 2008 What kinda gears came in a 75 620 seems really low Quote Link to comment
Jester Posted September 22, 2008 Report Share Posted September 22, 2008 What kinda gears came in a 75 620 seems really low 4.375 Just a thought. If a LSD for the H190 is around $400, why not buy a HB rear WITH disc brakes, spend the $250 to have it narrowed and call it good. You'd probably be money ahead and have disc's to boot.:rolleyes: Quote Link to comment

Actually I was thinking cut down the H223 and run the shorter H190 axles and bearing ends, but you were close :D Quote Link to comment
datzenmike Posted September 22, 2008 Report Share Posted September 22, 2008 I was thinking cut/re-spline the Hardbody axles. Slip into the H-190 axle tube for rear discs. I'm checking also to see if the backing plate can be swapped onto the H-190 axletoo. I like your idea too. Posi is what I'm after, rear disc is highly over rated. There's a Path near me with 4.625 gears and disc. (no posi) I got 4.11 with 33s and it's slow. Quote Link to comment
nismopu Posted September 22, 2008 Report Share Posted September 22, 2008 backing plates,bearings,axles and everything work in a HB H190 I know that for sure. Quote Link to comment
