What?It runs... Posted November 13, 2012 Report Share Posted November 13, 2012 Alright, so I've begun some work on a 1970 pickup I had in high school. I have recently picked up a nicely built L20 and would like to change out the rear end and perhaps the brakes. Which rear end should I use that may also provide some independant suspension? I'm relatively new to the world of japanese cars and will welcome any suggestions. Thanks for your time... Quote Link to comment
flatcat19 Posted November 13, 2012 Report Share Posted November 13, 2012 Keep it the way it is. That's my suggestion. New to Datsuns? Don't mess with it. Quote Link to comment
flatcat19 Posted November 13, 2012 Report Share Posted November 13, 2012 Another suggestion... Post pics. Welcome to Ratsun. Quote Link to comment
thisismatt Posted November 13, 2012 Report Share Posted November 13, 2012 may also provide some independant suspension? What do you mean? It's either independent or it isn't, and going independent is no simple task - all custom fab. Linking the rear again not simple and all custom fab. Quote Link to comment
jon521 Posted November 13, 2012 Report Share Posted November 13, 2012 go with a 240sx rear setup? i dont know anything about it, but for awhile i saw on craigslist in salem here a guy selling 2 521s, and one had all the work done to it to have 240sx full suspension set up. Quote Link to comment
I'm BLUE Posted November 13, 2012 Report Share Posted November 13, 2012 Welcome ! Any IRS will work ... People who know..... just do ;) If you don't have an un-disturbed workplace to set the truck from start to finish ... It's going to be more difficult than it already is. I can see a cool $850-$1,000 being dropped right off the bat if you want NEW performance coilovers in general with IRS. Thinking specifcally Qa-1 coilovers. Than again other coilover setups could be cheaper ! Add more money for exhaust re-routing and more un-expected costs. Add more for driveline shortening or custom driveline. THEN... You choose whether to shorten cv joints and making custom a-arms ... More money. Bushings ... Metal needed ... To re-drill or to not re-drill ? E-brake ... Brake re-routing... Etc Etc Or You'll be swapping out lug patterns to ... 2 spare tires. Hopefully you won't end up disc rear and drum front. Infiniti Q45 350z or G35 ? 240sx IRS 30Ozx IRS 510 IRS 280zx IRS Lincoln mark viii IRS Ford Mustang Cobra IRS Cougar xr7 IRS Thunderbird 5.0 IRS Etc ? ^ track width issues on many of those. Just as many don't have LSD. Which is a big re-sale issue. etc. Soon youll have more into the rear suspension than the whole truck including the engine. Unless you're a sly guy with money and parts slinging. Not to mention down time or cost versus fun ratio and possible a heavier setup than the original ... You could also Keep it the way it is and enjoy :) Or Choose the rear end setup that you'll still enjoy 10 years down the road if you do ! I'll have $2,200 in an 8.8 straight axle conversionr into my 240z That's counting everything I can think of needing .. Feels almost impossible everytime I type that figure but its true. And it's my reference :lol: You have to be super accurate in wheel base measurements via plumb bobs , jigs , angles and measurements. Not to mention lots of free time and even more patience period. Sure you can do it cheaper than my figures. But do you really want a top notch system operating with cheap or half worn parts ? Some of those parts work and even a larger percentage won't work as well. Not attempting to discourage. I do hope you're a bit more prepared for the journey though. Good luck Dtp 1 Quote Link to comment
socaldatsun Posted November 13, 2012 Report Share Posted November 13, 2012 I thought the tri-link was a better set up for track? Quote Link to comment

wayno Posted November 13, 2012 Report Share Posted November 13, 2012 This is a very nice 520 that Bob3 put together, it took a long time to do, it was made to race on a track, although I am sure it's a nice daily driver, any conversion like your talking about should consider all 4 wheels like this project, otherwise I wouldn't even consider doing it. http://community.ratsun.net/topic/7446-project-mx520-top-secret/page__hl__mx520 Quote Link to comment

Some nice rubber. Stiffer springs maybe a larger sway bar to tune the over/under steer. Enjoy driving it. You don't want IRS! What for? it's a truck not a 510. It's heavy and has a frame. It will always handle like a truck but you can improve on it. . Quote Link to comment
socaldatsun Posted November 14, 2012 Report Share Posted November 14, 2012 I'm confused ...OP wants IRS no mention of tri-link or track ? I just assumed that was why he wanted to convert. Not sure about him but I wouldn't put all that work to convert and just daily drive it, I'd want to put that set up to good use :P Sorry ill just shut up now. 1 Quote Link to comment
datzenmike Posted November 14, 2012 Report Share Posted November 14, 2012 Never shut up. This is how new ideas are born. I'm worried that a perfectly good running truck will get cut up for an ill advised idea and then scrapped because the owner got in over his head. Quote Link to comment
DaBlist Posted November 14, 2012 Report Share Posted November 14, 2012 It's a Datsun PU. Best to keep it simple and on the road Quote Link to comment
what Posted November 15, 2012 Report Share Posted November 15, 2012 I have a 3:90 center section if its the gearing that you don't like. I am located in Salem, Oregon. This is for the H190 truck rearend. Quote Link to comment
What?It runs... Posted November 17, 2012 Author Report Share Posted November 17, 2012 Thanks for ALL the feedback! @thisismatt, clearly IRS is a full time thing. I'm not new to the car world. but thank you. I am sort of new to datsuns and am really excited to get my pickup back on the road. I do have a full machine/fab shop at my fingertips so the work isn't the issue. However, being relatively new to Datsuns, I didn't know if there was a particularly common rear end swap. @DTP, thanks for all the info. I may leave it alone for now just to get it on the road and to a couple of events. I look forward to meeting some of you and seeing what you've got... Quote Link to comment
