Well some progress on the zx over the weekend me and XNKE as you guys know him ripped all my hand made megasquirt harness  out and ran a diyautotune pre made 10' harness and mounted my ms in the glove box instead of the driver side kick panel. I used a ford relay/fuse box from a cop car and tied it into the acc fuse box. It now powers the whole car and is easily accessible under the hood beside the battery where the fuse-able link box used to be Ohh yeah we done away with that horrid thing also. I finished the down pipe to run a 3'' full exhaust i had to turn down off the flange in 2.5'' then flared it up to 3'' and turns under the car. The z32 trans is almost disassembled Having problems getting the main shaft out of the center plate. Stay tuned...

Got that mainshaft out today...centerplate is broken between the bearing bores. I have plans on how to fix it, but the gear WAS literally brazed onto the shaft. Found where all the brass came from...2nd gear synchro looks great on the outside but is completely missing on the inside.

Gets worse...Pulled the mainshaft gearset down...I found where all the brass came from. 2nd gear synchro cone/engagement teeth has a section broken out of it, that's what ate the synchro cones up. Also has a missing lock ball, 2nd gear was not locked onto the mainshaft.

 

Sorry bud, we're gonna have to go trans hunting again. What are you doing tomarrow?

Hey guys sorry for the long wait! almost a month ago i went under the knife to get my super crappy pain in my low back fixed and had my right si joint fused together with some new titanium pins (to save weight) i told them not to use stainless BECAUSE RACECAR!!! Its been a few weeks now and i cant remember ever feeling this good. So back to the zx racecar. The broken gear is ordered for the z32 box and im soon to be ready for the racetrack. For those of you that dont know look up ncm raceway in bowling green ky. more to come.

Well between japan and texas nissan dealer i have all the keys and spring rings and junk for this z32 box! hopefully next week xnke and myself will get it together and in the car. Just for the record if any of you guys plan to go this route save your self some cash and alot of time just buy a 98+ jdm transmission with 25k miles on it and call it a day. it would have been cheaper for me to pay 800 for a known good box than get a junkyard one for 100 bucks then 300 for master rebuild kit then 100 for small broken parts and worn out things that do not come in the MASTER rebuild. All to crack the center plate (plate adapter) of the trans trying to press it apart to do the rebuild in the first place! By the way the plate adapter from nissan is $110 and it is a revision so you got to buy the new 1st gear to work with the new plate $298. so if you have as much trouble as we did this fresh new fs5r30a trans will cost you a wopping 900 bones not counting man hours if you pay someone to do it for you. And lets not forget the $400 L6 Adapter from hoke and bell machine work ohh and a new drive shaft too. I hope this thing is unbreakable in the end. soon guys soon!!!!

NEWS!! The trans is in the car and man this thing is big and fat. using the hoke adapter the shifter location is about 4" back from the t5 which required trimming of the tunnel shifter hole. also the tailshaft end of the trans so big i had to trim a ear off the trans crossmember factory mounts on the bottom of the tunnel to clear the case. JTR said the center of the tailshaft should be 4" from the top of the tunnel my shifter is HARD on the bottom of the tunnel and tail shaft is 4 1/8 so should be ok with some hammer time. the reverse and saftey switch on the passenger side are on the tunnel. the stock trans mount fits on the z32 box but the crossmember needs moved back behind the mounting ears in the tunnel and im going to slot the trans mout and weld on washers to relocate the holes some to move mount reaward to match the crossmember. the drive shaft looks to be 2.5" longer than the t5 was although the r30a looks longer its not! I still need to put the new diff flange on in case its thicker and measure again and i will post length for sure with pics.

update guys i have made a temp crossmember and made some room in the tunnel. now on to the cool stuff a buddy of mine gave me a cop car driveshaft from a crown vic that we could shorten for my z. xnke and myself took this 60ish inch monster aluminum driveshaft and used the trusty lathe to cut the weld and remove the weld yoke from one end. The total length for what i neened was 25 1/4" center to center and it ended up being 25" oh well also if you guys are using a 2.5" or smaller shaft yours will be around 26 to 26 1/4 long but this monster is 3.66 in diameter so i could not run it with the slip yoke only pulled out one inch its about 1 1/4". i got napa 1310 to 1330 u joints for this project because joey said the shaft had 1330 u joints well i was assembling the slip and diff yoke while jake (xnke) was finishing up the shaft on the lathe then we realized upon trying to put the ends on the shaft this beast has 1350 u joints not 1330. so back to napa to get the 1310 to 1350 joint that were 28.50 each OUCH! i removed the wrong u joints and replaced them with the right ones about 3pm last evening. this thing made it into the car last night around 10pm. it fits without interference all but its about half inch off the bulge were the handbrakw cable protrudes into the tunnel. hopefully the soft z32 trans mount i used dont let the trans move enough to bang the driveshaft on the floor or ill have to get the hammer out again!!!! i had a local guy make me a new clutch line about 3" longer than the stcok zx line because mine would not reach the slave. also used the lathe to cut myself out a bronze bushing for the shifter so i dont have to use the cheap looking plastic ones that came with the shifter. will be driving soon guys and laying long elevens in the street thanks to the obx l.s.d oh yeah its installed also filled everything with royal purple 75/90. more to come!!!!

oh by the way guys all you running this trans (fs5r30a) AKA 300zx z32 manual trans the bronze shifter bushing that everyone sells you can make your self the od is 14mm cut it for 13.98 for press fit the id is 8mm and it is THIS LONG oh you cant see my fingers? can you? well i will have to measure it and get back but the steel bushing that you remove is the length you need to cut the new one. This is if you dont want to pay 15-25 bucks for a pair of them and wait for shipping. peace!

I forgot to mention the speedo drive from the t5 does not fit the z32 box it is way to small and just falls into the trans. for now i used a expand tite rubber plug from autozone. I think it was 1" to 1 1/16th and at almost full tight it is very snug. there is an end from a pathfinder that will work with my cable and fit hole in the trans but gotta find part number again.

I made a complete 3" turboback exhaust all mandrel bent with no muffler tonight took me 8 hours of cutting and fitting!  the down pipe slips into the flex joint then runs back to just before the rear sub frame were its connected with a band clamp then over the sub frame into another band clamp then exiting at the rear bumper. This way i can remove the whole exhaust and not have to cut it apart when crap needs fixed and the exhaust is in the way!!!

well nothing bad in the trans fluid light syncro shimmer and some steel stuck to the mag on the drain plug. refilled trans noise still there started thinking pressure plate bolts? so scopeed in the bell housing and all bolts are in and all trans front cover bolts are in but still noise even out of gear reving. so removing trans AGAIN!!!! to see if clutch disc has came apart there are marks on the pressure plate like a bolt has hit it but all in random spot like something has been bouncing around in there but i cant find anything thoughts guys???

The noise is for sure in the trans first and second gear sound terrible but much more quiet in any other gear but what gets me is it shifts fine no grinding or crunches!! guessits got to come out and soon!!!!! I MISS MY BooST ahhhhhhh

Well noise fixxed me and xnke ripped the box out and found a thin gear shaped steel part behind the reverse gear that was missing a c clip and was flopping around on the shaft lol. It had rounded off all its teeth and was sawing its way through the tailshaft housing sooo we removed it because we could not see a need for it other than possibly noise or vibration damping. This is where all the steel on the magnet drain plug came from. Im going to knock my clutch and flywheel off tomorrow and replace my rear main seal for it is seeping into the bell some. then she goes back together and some gopro footage per xnke!!!!
