Rollover_Red Posted April 18, 2011 Author Report Share Posted April 18, 2011 how much you want to pay? how much you willing to go down on the price? im still new to the whole 5 speed thing...... i drove a buddies 510 with a 5 speed and he told me they are not really cheap, but i do have some random parts as well for trade plus cash on top.....

AtomChurch Posted April 18, 2011 Report Share Posted April 18, 2011 As long as you have a manual already its not too hard of a swap. If you get a short transmission you wont need a driveshaft. Post an ad up in the parts wanted section with your parts for trade and the cash your willing to add. Quote Link to comment
Rollover_Red Posted April 18, 2011 Author Report Share Posted April 18, 2011 yeah i wasnt sure where exactly to post this, i thought since it was more of a question rather than a ad, i thought to post it here. =] if i can find one cheap enough, ill just go 5 speed, but if it gets out of my price range, then ill just find a 4 speed to slap back on and drive away....

inline4 Posted April 18, 2011 Report Share Posted April 18, 2011 it ran when I pulled it, it had needed a slave cylinder. but I do have an sss head and I'm mulling over putting an L back into the 510. Quote Link to comment
Rustina 510 Posted April 18, 2011 Report Share Posted April 18, 2011 I have been told that the dogleg is a week 5 speed for the weight of the 510, so I got a 280z 5 speed. They are quite common but you will need a modified tranny mount and a shortened drive line. Hope this helps your car a bit, It would suck to get a weaker tranny with all your cash and then drive it to hard and burn it out in 3 months, get the tuff stuff so you can play longer and stronger.

izzo Posted April 18, 2011 Report Share Posted April 18, 2011 its weak for a 510? haha, its no more weak for a 510 than anything else. I had a long tail dogleg 5 speed in my truck, and a short one in my 510. They did just fine. I hauled huge loads with my truck, rallied it, etc. Never gave me any problems. I rallied the 510, and it got stuck in gear (dunno the history of it tho either) and after i got it unstuck, it would grind in 2'nd and 3'rd if i didn't shift slow.. Still works today, and that was over a year ago. It is a weaker trans tho.. one from a 280zx is good like rustina said, you could also get a transmission out of a 720 pickup and swap the bell housing with one from an L series trans, and its really strong as well.

Rollover_Red Posted April 18, 2011 Author Report Share Posted April 18, 2011 ok so cost to get a trans installed as well as reliability. give me some comparisons...... 280 trans cost/efficiency as to dogleg cost/efficiency............ Quote Link to comment
izzo Posted April 18, 2011 Report Share Posted April 18, 2011 the dogleg will be cheaper. It will be reliable if you dont go out and rally the piss out of it. It will do just fine for daily driving, getting on it etc. You wont have to have a driveline custom made. They are weaker.. For the 280zx, it is stronger, i think the gears are better for highway speeds in 5'th. You have to cut the floor shifter hole back, get a custom drive line, and also mod the transmission crossmember (maybe a longer speedo cable) Ive seen doglegs go for 150 around here, your area 250 Every 280zx trans i've inquired about, it was from Z guys and they wanted 450 for them. You could probably get one cheaper then that. Quote Link to comment

PPS, my tranny blew up yesterday........ The 200sx 5 spd dogleg is exactly the same length as the stock 4 speed. It also has exactly the same gear ratios and an overdrive 5th and the speedo cable is on the same side. The rear mount will need modification but you can use your old drive shaft. The dogleg is capable of easily handling the L16 and capable of the L20B engines. The 620 and 280z/zx 5 speeds are heavier duty though and will need the drive shaft shortened and longer speedo cable on top of the other mods.. Quote Link to comment
DottiBlue Posted April 18, 2011 Report Share Posted April 18, 2011 Theres a 280zx in the sponsor pick and pull right now. i thinkit's a 5speed. Don't know how close that is to you. Quote Link to comment
Dat510_Chris Posted April 18, 2011 Report Share Posted April 18, 2011 Ive had both 280zx and 620 5 speeds in my 510, from what i hear and tested the 620 is better than the 280. I bought my 620 5 speed from a junkyard for 250, if I remember right 77'-80' 620 is a direct bolt on to the L series or at least to an l18 also requires shortening the drive line. If you find a 77 or 78 you may want to open it up and check the nut holding the assembly together to see if its loose, 79 and 80 they changed it to a reverse thread so it doesn't come loose on you. Here is my 78 620 5 speed Quote Link to comment

Shagy Posted April 18, 2011 Report Share Posted April 18, 2011 what happened to the days of going to the junk yard and pulling a trans and walking out payind $150? Quote Link to comment
Rollover_Red Posted April 18, 2011 Author Report Share Posted April 18, 2011 dude, the last time i saw a 510 in the local junkyard, it was parted out in less than a day...... Quote Link to comment
Shagy Posted April 18, 2011 Report Share Posted April 18, 2011 not 510 trans specific...we used to goto the yards in south San Diego and see Z's for days!!!!!!!! $150/trans..... $151 if you counted admin fee... Quote Link to comment
hitch Posted April 19, 2011 Report Share Posted April 19, 2011 I don't know about the West Coast, but in the SE, everything was crushed during the last steel run up 4-5 years ago. Unless you find one behind someones house, they just don't exist in junk yards any longer. My sister is in the steel industry, about 4 years ago, they sent 4 ship loads of scrap to China, they paid top dollar. I only see Datsun parts getting harder to find in the East.

DISLEXICDIME Posted April 19, 2011 Report Share Posted April 19, 2011 Any 5 speed now days is going to be a ticking time bomb . The newest 5 speed you can get will be 28 years old and more then likely nead bearing's. Quote Link to comment

Here is my 78 620 5 speed The FS5W71B 5 speed came out for the '77 model year and was used in the 620 truck and the 280z car. For '77 and '78 the truck 5 speed was identical to the 280z and first year 280zx 5 speed. Same gearing, same strength. If there was a difference I usually find the fill hole is on the driver's side on the truck and on the pass side for the car. The '79 truck had different gears (wider ratio) and two extra switches besides the reverse. Quote Link to comment
Rollover_Red Posted April 21, 2011 Author Report Share Posted April 21, 2011 does anyone know if a wagon tranny will fit in my 510 no problem? i might pick one up today but if its not the same size, i wont get it, can anyone help??? Quote Link to comment
banzai510(hainz) Posted April 21, 2011 Report Share Posted April 21, 2011 L Motor 4 speed should be the same sedan and wagon. Quote Link to comment

The 510 wagon and sedan 4 speeds will swap perfectly. However, the goon tranny has a wider ratio gear set because of it's intended use for carrying loads. This isn't good or bad it's just something you may notice when driving it. It may feel like you barely get the clutch out and onto the gas and you have to shift into 2nd. ..........Sedan.... Wagon 1st... 3.382...... 3.657 2nd.. 2.013...... 2.117 3rd... 1.312...... 1.419 4th... 1.000...... 1.000 If the sedan has a different rear end ratio than the goon, (I can never remember) swap the speedometer pinion from the old tranny to keep it accurate.While tranny is out, if you have never replaced the release bearing do it now, it's cheap insurance on a high wear difficult to get at part. Also replace the rear seal. they are only $7 and easy to do. This is also cheap insurance against a wet oily driveshaft and a dry tranny! Quote Link to comment
