Rota RBs 15x7 + 25 all around with Falken Azenis 205/50r15 Stock 510 struts with some ... unknown... lowering springs - currently running an 8mm spacer to clear the struts- needed longer studs - 10mm spacer coming to give a bit extra clearance

No Update on the LSDs yet... but do have one on the wheels! Test fit them Last night... unfortunately these tires are wide - with a 5mm spacer I have about a half mil between the tire and the strut... oh an only about 8mm of thread for the lugs to grab... looked great, but wasnt gonna work Little bit of research and some help from the guys over at RDZ Motorsports and I had some extended studs in there today- which ever ones are 45.5mm long with a 12.9 knurl- pressed right in and gave plenty of thread- All mounted up and drivable- pretty tight fitment but clears- got some 10mm spacers coming - pretty stoked Other stuff--- Picked this up off of Ebay for $23 shipped! Great hat, nicely done Oh yea almost forgot! Stickly rubber came in- these are getting mounted up on my 13" steel wheels- only $75 a piece!

New Wheels!

Update- Its becoming Christmas in August! Got wheels and tires and the first LSD in today- Tomorrow is Lugs and the complete LSD Diff- then Thursday is a 510 Hat and Race Slicks- Here are some teaser shots- Completely disassembled the Bad R160 just to get a feel for what goes on in them LSD Unit # 1 Showed up Wheels Showed up - 15x7 +25 Rota RBs with 205/50r17 Falken Azenis Teaser Shot of the Wheels on the car- its going to be very close, these tires are wider then the prior 205s I had on there, so the 5mm spacers I got I dont think will work... might need some longer studs and 10mm spacers.... will update tomorrow when I get the correct lugs in and get her on the ground.

Was bored tonight so i pulled apart the bad 3.9 rear diff I have lying around- figured i would get an idea of what ill be dealing with when the two LSDs I have coming this week get in- Did a pretty good number on that pinion gear- not sure how to get those retainer clips off under the bolt heads... guess ill just grab some pliers and try to bend them- In theory... I can have two usable ration LSDs out of this deal... I have a stand alone limited slip coming that can go in the 4.11 diff... and I can pull the ring gear from the bad 3.9 diff and put it in the complete 3.7 LSD i have coming... The 3.7 and 3.9 use the same pinion gear according to my haynes manual so i can just swap the ring gears. In Theory... More to come-

Thanks Dave! That is some great info and help. That might help explain why my front end pushes in some corners - ie lacking grip from that front outside tire That was the next step on my list was to start messing around with Suspension and Geo- Still trying to wrap my head around all the different possibilities when it comes to suspension setups- while still keeping it street able. And all that info is definitely a great start. Needed to get new tires anyway since the ones I am on are pretty toasted, so got a killer deal on some Hankook F200s in the C91 super soft compound, from aimtire and couldnt pass it up. Also have a set up rota RBs with Falken Azenis on there way for street use. Also happened to stumble upon a couple Limited Slip Units - so I now have one LSD Unit and one complete diff headed my way. unfortunately I will be a little limited on what I can spend in the short term, but looking at your options definitely could be something I will be looking into in the very near future. really enjoying the whole process of taking this car to the next level. The wealth of knowledge on here and the Realm is almost overwhelming.

Too many photos from Sundays AutoX to upload them all so here is the link and a few choice shots- Big updates soon to- New shoes for street use - Rota RBs wrapped in Falken Azenis - Full Race Rubber for the 13's (Hankook F200s)- Limited slip unit- all should be in next week.

Thanks ! Installed the 4.11 open diff last night, just wanted to get it back on the ground and running- still searching for a donor LSD- nothing worth posting picture wise. New diff is great though, gear noise is all but gone, and definitely a bit quicker then the 3.9. AutoX on Sunday, cant wait to really see the difference

FrankenDiff adventure is set to begin- Was unable to find a complete 4.11 LSD Diff (The Holy Grail of Diffs I guess)- so time to build my own. First step complete - sourced a 4.11 Open diff from an older Subaru- Next step find a LSD from a Subaru will probably be a 3.7- Then pull the LSD and swap it into the 4.11 - I will do my best to take pictures and keep you guys updated on the process

Pulled my rear diff-

So the rear diff has definitely seen better days - drained the gear oil again and the magnet was full of metal- again- after only 100 miles or so of use. Pulled the diff and sure enough the gear coming off the driveshaft has seen better days So I am going to use this as an excuse to upgrade to an LSD - anyone got one?

Been a while- got to drive it around a bit last night to try and recreate it... unfortunately cant get it to recreate- but... there is quite a loud whirring noise coming from what sounds like the back end and not the transmission. Possibly the rear diff? Took a passenger and they pointed out that is is definitely coming from behind the transmission. Happens in 3-4-5th no noise under engine braking or accelerating loads- but when your "coasting?" or just barely on the gas it is quite loud. Also happens in any gear when you are coasting and clutch in. Just recently replaced the fluid in the diff and it definitely wasnt clean and there was quite a bit of gunk around the magnetic drain plug...

I have dual DCOE 40s on my L20B - Honestly couldnt tell you much about them other then they do guzzle fuel and sound great. I do know I have an reground cam - I believe it is Comp Cam # 79-131-6 Grind 2805 - if I am correct is has .050 duration, 236 Deg, .460 Lift, 110 Deg Separation. Prior owner put them on, I had then "tuned" ... I put that in quotes as it was a favor and done pretty quickly... and have been running them since - Mine dont like to idle until there is some good heat in them - could probably be fixed-and I definitely run rich- also she sounds like she is making dynamite popcorn at any hint of engine braking - but its a race car... Here are some shots Plenty more if you follow those back to my photobucket

That is a possibility - ill have to drive it again tomorrow- part of me remembers it still klunking or what ever for a second after re engaging the clutch- Any way to further diagnose it?

Took the 510 on its longest journey yet- up to Limerock Park (1.5 hrs or so) got a to take a couple parade laps - pictures latter when they are up... Any way ran into an issue on the way home... The car drives fine as if there is no problem - no issues getting it in gear, no odd noises, other then the whine in 4th and 5th, but its done that since I bought it and I always figured it was because there was nothing to insulate the sound (no carpet or anything inside the car) I believe it is a 280zx 5spd What it is doing is that when shifting or in neutral with the clutch in it will get a rattle or clank, almost as if there is a piece of metal in there that only gets picked up and bounced around sometimes. but it only happens when the clutch is disengaged i.e. pedal to the floor, seemed to be more prevalent in the 2nd to 3rd shifts but had it happen in the 1st to 2nd and 3rd to 4th. Just changed the transmission fluid last week. I had the speedo gear pop out of the transmission housing- no damage to the gear, minimal driving while it emptied ( 1 shift, and maybe a mile) Replaced with Redline MT-90 transmission gear oil - yellow metal safe - felt like there were smoother shifts after changing. When I drained the remaining transmission fluid it came out surprisingly clear with very few metal shavings on the magnet. Any help or insights appreciated- been searching, still searching, but I have a pretty limited knowledge of transmission. Thanks!! Devon

a few more

A few more from the last couple Auto X Events

Just go to your local dealer- they can order them. you just need the part number... unfortunately i thought it was in my thread but its not - garage is too far away right now- if i remember correctly they are the 280 self locking nuts-

Pushed her back into the garage... after she had to spend an unfortunate night outside... poor datsun

I used whatever NAPA cable was recomended for the 510

I ran mine through an open hole at the speedo level more toward the outside edge of the firewall, around the clutch master cylinder , then over the bell housing and down under the car to the transmission - there should be metal clips the whole way on the firewall. sorry i dont have pics but i might be able to get them for you. Might not be the stock routing but it kept the cable with nice smooth swooping bends and without too much excess

Put a bike rack on the Datsun today - ready for summer!

I sold my subaru wagon so I could get a dime- lol - still miss that car - and I have a Tacoma truck as my daily.. but sometimes I want my bikes and my dime- also as cool as it is to have a killer race wagon- props to anyone who races a wagon- I wanted a fun little car I sold racks at a bike shop for 7 years- trunk racks SCARE me - those things are so sketchy- they scratch paint (ummm i have a ratsun so that doesnt matter) - but they get intalled wrong all the time and they really work like crap... plus the gutter rack system for the 510 is so easy- if you need a dirt cheap solution though they work - with the roof rack though I can put my surf boards up there too :D So so so true lol As for what I did to my dime today? Drove the shit out of her- it was a gorgeous day here in CT so I drove her to work and then on my way home put the hammer down and went the scenic way home - my ears are still ringing... i think i need a quieter exhaust

ordered a thule roof rack for it so I can carry around my bikes... despite not having a backseat i still cant fit a bike in the car... damn rollbar
