240zRacer

not the best choice on motors but actually a smart idea since the original motor was junk to and always breaking down, a toyota mr2 turbo swap might have been a better option or a v8 conversion.

thanks for the replies i will just stick with the oem, spacers would put the welds out past the fender lip.

i recently noticed i have a caliper hanging up so i figured while im at might as well upgrade, here is the issue i am using weld drag lites on the front and due to the way they are shaped they actually slightly scraped on the raised letters on the stock calipers. as you can see in the pic i attached the caliper and the face of the wheel hub are level well actually the raised letters stick out a tad past so most rims this isnt a issue since the wheel has a raised mounting surface. well on the weld rims its flat, so my question is do the 4x4 ones stick out more then the OEM ones? if they do i will just get a reman OEM one. i drew red lines to the areas i am speaking of.

well the old stuff is out and the cutting and measuring has began, sorry no photos yet my daughter has lost my camera so it wasnt with when i visited the shop. as you all saw i posted the old rear end set up stuff for sale and the bulk sale is pending, however dont feel left out just yet i have some very nice tires and rims still here i think i could be persuaded to sell, but since i cant post a for sale thread yet as im not a donating member long enough PM me if your interested in a set pair of rota rb with drag slicks and or a rare set of ROH rims and toyo tires. they will all be on ebay this week but i figured i would offer to you guys since i personally know how hard it is to get nice rims that fit right on these cars

the car is still a work in progress, my goals are a car that can be driven on trips and around town on a daily basis but yet go to the track on weekends and have some fun. i was running low 10s on the r200 set up but i plan on adding a bunch more power so i am going to solid axle.

sorry for the delay , the shop my car is at has been back logged but now things are moving along, i will start posting pics this coming weekend, on a side note due to the rear axle being a different lug pattern i will also be selling a very rare set of rims for a 240z, so if your looking for a amazing set of rims for your 240 that no one else has and that fit perfect let me know. i can email photos of them , they are 16x7 and the perfect offset for a 240z front and rear. also the rest of the rear end parts will be up for sale shortly including the custom 900 hp DSS axles and modern motor sports stubs and cv conversion

in a few weeks i will be selling a CLSD that has already been rebuilt with the new clutches, in case you want the clutch style, from what i read the style you got there is weaker then the clutch style.

The car is going threw some major changes soon and while i spent allot of time and money making the independent set up bullet proof the new set up will be shooting for deep 8s if not 7s so this requires major reworking of the frame and unibody and rear set up, as the car gets cut into and things progress i will post pics. we are looking to start the surgery in a couple weeks. On a side note I will be sure to offer every thing from my rear set up on these forums before i put any of it on ebay. so any one looking to beef up their set up start saving your pennys and watch for a official for sale thread in a few weeks. some of the parts i will be selling are a RT style r200 front mount, a aluminum r200 conversion mustache bar with polyurethane mounts, polyurethane control arm bushings, the control arms them selves and the hubs, modern motor sports Billet 280ZXT CV Adapters 70-78z, modern motor sports Billet 4340 280Z Stub Axles in 4 lug pattern, DSS stage 5 900 hp axles( 81-83 280zxt style used when converting a 240 to cv with the modern motor sports kit ) and the adapters to mate to the modern motor sports CV adapters. I also have various r200 rear housings and parts, including housing with 3.70 ring and pinion with the larger ring bolts( no diff installed) a open r200 diff with the small bolt holes, a complete r200 housing with 3.54 gears and a freshly rebuilt CLSD with the spacers removed and the clutches and steels added ( the ring and pinion make a whine on deceleration ) I also have the highly sought after aluminum rear drums as well. any way this isnt my official for sale thread but i wanted to put it out there so that when the time comes you guys can have first dibs on anything you might think you would want. I will be willing to part every thing out or make some one a deal the complete package. any way stay tuned for pics and updates as they happen.

the axles cost around 900 bucks, mayo if you look at my pics you will see i use a 5.9 inner cup and it doesnt hit any thing due to being a little smaller around then the outer porsche style and its just as strong we originally planned on the same inner and out but due to the space allowed we went this route, which brings me to the update frank found out what caused the axle to fail, under full squat the axles are a little to short and it allowed the inner cv to pull out to the very edge of the cup and peeled it back like a banana. The shafts have been extended slightly and the axles will be back here tomorrow just in time for fridays racing i used this opportunity to modify and improve my mustache bar so the diff should be even more solid then before. if any one is running a 240z with modern motor sports cv conversion and wants axles frank has all my specs saved, but you need to make sure you measure for the length with the car at rest and at full squat to make sure you get the right lengths, i only measured at rest and we assumed it wouldnt change much at squat but it does. i will keep you guys updated on the axles strength, he swears they will handle close to 1000 hp and im only at half that in a 2500 ib car so i shouldnt be able to break them.

sorry been away, ok so here is the update , as for the lengths my new shafts where made to the exact lengths i needed, not based off the oem shafts, here are some pics of the new axles. new axle compared to oem adapter to connect axle to modern motorsports hub adapter on the modern motorsports hub installed and now for the bad news , i got 3 passes out of them when this happened. thats right i shattered a stage 5 900 hp axle lol, they are under warranty so i will have them upgrade the inner cup even more even if it means moving my diff up to allow for a larger diameter inner cv. the good news is i got a new best 60ft before it broke, 1.45 for those of you not into drag racing thats a amazing 60ft for a daily driven real street car.

sorry already shipped the axles to the driveshaft shop, i will probably get back the axles but its not hard to picture a broken shaft, if you ever seen a axle broken down to its individual parts you have a shaft that is splined on both ends that inserts into tripods on either end, well the shaft snapped right there exactly where the splines start on the shaft. the drive shaft shop said that in truth at my power level all i really would need are upgraded bars, they said the ends and tripods are very strong already, but i figure while i am having them done might as well upgrade the entire axle.

Ok i figured i would update this, i spoke to frank at the driveshaft shop and he is going to make me a set of axles that will be a direct bolt in for the modern motorsports 280zxt set up , i sent him my stock set and he is going to use them to make me a set that uses the better porsche style ball cage ends and high strength bars i will post pics when i get them back, i will also have him make notes so that he can make these in the future for other people making allot of torque.

i just found a used set on ebay and bought them, the guy said they are sloppy but if i just really need the shaft to fix mine so i should be ok there, but i still am looking for some billet or high strength alternatives.

i just took the axle apart it snapped the main shaft right where it goes into the tripod splines on the diff side, my tq is 545 at 4500 rpm, i would like to try and make this set up work as i just spent all the time and money on this r200 swap and parts as i was told there are guys running 9s and pulling the wheels on this exact set up and thats more then i plan on doing. i am currently looking for some used ones to get the car back running does driveshaft shop or any other company make a stronger axle option for this set up? seems that if modern motorsports would go threw the hassle to make the kit that they would also offer axles.

more information: the company fenco list 2 different part numbers for right and left, the company cardone shows 2 part numbers left to right as well, the company gsp shows they are the same part right to left and the nissan dealer i called says his system shows the same part for each side. for every one i had them look up 1980-1983 280zx turbo which are the only years that work i believe, in either case the axles are discontinued for each manufacture.

I have the modern motor sports kit in my 240z that lets me run 1981 280zx turbo cv shafts , however yesterday i snapped one when i tried to launch on drag radials for the first time, i was only launching at 3 grand but it snapped like a twig. I am making 500 whp but i was told that the r200 and these axles can handle that kind of power with ease, so my question is was this a fluke? or do i need stronger axles? if i need better axles who makes them? i can not even locate any out parts stores that can get these discontinued axles. the guy at wolf creek racing sells a set up thats good to 400 hp but it will not work with the modern motor sports conversion as its meant to be a direct bolt in for the old universal shafts. so in conclusion can this set up be made to handle this much power and not fail or do i need to look into a solid rear end swap?
