I love how it looks with all the suspension put together. And the underside of the car looks ace.

Thanks a bunch man. It was a big pain in the a** getting it that way, not sure if I'd do it again next time or not.

Did work. Shes getting there. Need some small ticket items like more hoses studs etc. Megan Racing PS pulley was installed but didn't rotate true. Appears that the broach is off center and crooked. Kinda like the UPS Powdercoated grey look better anyways. Might make my August 14th Carolina Nissans meet deadline. Wish me luck.

Put these on today. Also installed new throw out bearing. Didnt take pic of clutch disc but its the ACT 6 puck sprung hub. Painted more stuff for engine. Bought more car parts too, Greddy catch can and circuit sports overflow tank for cheap. Took turbo off cause I need longer manifold studs and new turbo elbow studs.

[xiaphin]

Hottest day of the year when we installed this thing. Stuff on upside down/backwards, do things twice, put things on take things off put back on again. Car gods hate me. Not my glasses by the way.

Well it seems to have been worth it.. haha. Really interesting on colors for the motor. I would have never picked em out, but it turned out REALLY good.

[xiaphin]

Got my wheels painted though... black primer... three coats of UPS Brown... three coats of clear... Im diggin it... Also painted those fugly lime green ST sways with leftover primer and cleared them... Pics with flash compared to without result in massive color shift... should be interesting to see what they look like at different times of day... of yeah also painted part of rotor that rusts

Did open heart surgery on my car only to find another clogged artery. Broken stud in turbo outlet housing and couldnt remove while on the car. Removed turbo from car and tried using a couple removal tools. Snapped it off in the housing, center punched it, center drilled it, drilled it out, then retapped it to chase the threads. Installed the studs that came with my Greddy Elbow



Reinstalled, went to put on my PBM downpipe but it wouldnt fit. Pipe is hitting bell housing and bottom of car. So I tried putting on the greddy... no good either... stock unit didnt fit either. All 3 were hitting the bellhousing. Thinking that the FP manifold doesnt put the turbo in stock location and needs to be spaced out about half inch or so. Took some measurements from block and firewall. Could somebody measure the location of stock turbo with stock manifold, that would be nice. Took some pics. Anybody running the Forced Performance manifold with the PBM downpipe? If anyone has let me know what u did to get it to fit.

[xiaphin]

Had problems with manifold and PBMand posted it earlier, so just a link to it - pbm-cobra-downpipe-and-forced-performan ... 05949.html

Went with the stock manifold and the PBM Flex, Megan straight pipe and Apexi N1 Dual bolted up just fine. Had the insulator mounted to the PBM with both bolts but it was so twisted that I went with one instead. Lowered it a little more than an inch. Undercoated that bottom of my gas tank after these were taken, getting rid of that white overspray. Gas tank was resto'd with POR 15 Fuel Repair Kit and Walbro fuel pump. All hoses replaced. No pics of that.

[xiaphin]

Got my 225/50/16 BF G-sport 2's mounted the other day. Spme shots of rims on car and lack of clearance, definitely have to run a spacer up front. Sways, JGY driveshaft, and IC piping installed. You are either gonna hate my rims or love them. Look totally different in sun compared to low light same goes with flash - no flash.

nice build! you should get some doo doo brown interior to match your car lol

King pin does not need to be torqued as high as the FSM states. Some versions of the z32 rear hub actually had a design where the hub extended up, and the king pin went through the hub. If the FSM calls for such a high torque load it's for the hub. Since your aftermarket hub does not go near the king pin, I would just hit it with an impact.

There are also 2 different types of king pins, some are thicker than others. My z32 e-brake king pin uses a king pin that required the hub extension. What kept happening was, my springs for the pads kept slipping off. I made spacers using modified washers, had the king pin sitting higher. The springs had more room to seat. Worked great.

Pictures for clarification:

Different types of king pins. I had the pin on the left.


Shallow ping with extended z32 hub.


Different z32 hubs.

My rear hubs are not aftermarket they are Z32 and are like the hub on the left in your pictures. Think I torqued them to 175? Don't remember.

There are also 2 different types of king pins, some are thicker than others.

Did not know this. What year Z32 douse the hub on the right come off of? I'm gonna guess 89-90 NA.

Funny you should say that cause guess what, I am. Brown with grey accents. Gotta finish my dash gauge mount and steering column gauge mounts before I can paint. Speaking of what do you guys think of my first attempt? Never seen this done before, two 60mm Defi BF White gauges sandwiched by a 70mm 350z door vent. Space is non existent here. Still have to reinforce it and paint it.

[badbob2121]

hmmm i havent seen that before... i like the idea

[S13AL]

Is air going to be blasting the back of your gauges?
I don't think that would be a good thing to have when your heat is cranked up.

[xiaphin]

Nope no air will be blowing on the back of my gauges. Am going to modify/make some a plastic runner that will direct air into back of vent just like all of the stock vents.

[xiaphin]

Here are some pics of my progress with the Autopower Bolt in cage, interior and sound system. PITA getting the cage in while retaining the rear interior panels. Wired up my amp (cant believe that tiny thing is 1200w 4 channel), with help from a http://www.sonicelectronix.com/item_177 ... ZCK44.html (already ran my speaker wires so if anybody wants the wire LMK they are 16GA silver tinned copper), installed head unit, picked up an Odyssey PC925-A battery, cleaned up all my switches since they had overspray on them from previous owners 10 ft. paint job, flipped injectors, made and installed AN fuel lines. Finished the dash gauge and vent mount, installed it. Drilled four holes in back of mounting plate, epoxied 10-24 threaded rod on backside, fastened to dash with two aluminum strips and wingnuts. Upload pics is anyone's interested. Going to mount my Wideband and 2 other 60mm defi gauges below my cd player. Mounted PS resovoir by clutch slave using one hole for that green thin and tapped the other. NO room with the Apexi intake. Anyone else using this kit? Its for a Z32 MAF if that makes a difference. Time to enjoy the good beer seasin and drink some BCS - for those who dont know http://www.ratebeer.com/beer/brooklyn-b ... stout/531/

Defi daisy chain power wires were too short to finish center console over weekend. Should have longer ones today. Modified heater core vent to flow air only to the 350z vent. Used some plastic and cut a 3" flex pipe that I found in the roofing section of Lowes. Safety wired, siliconed, and glued together. Also was able to start and finish mounting all my controllers into the glovebox. Constructed out of 3/4 wood wrapped in gray suede to match headliner, door inserts, and glovebox. Held in place by 1/2 x 1/8 thick aluminum and Velcro. Pic dump.















Defi link and gauges up and running. Turbo timer installed. DIF fan controller and boost controller almost complete. All wires soldered and labeled. Installing LM-1 wideband tommorow and wiring it to dataloggit box as well. Connected PowerFC dataloggit to computer and downloaded enthalpy's ign timing map. Read that these values are far superior to the map provided on the FC from Apexi. Going to use scotties tune taken from freshalloy as a starting point. Hoping to fire it up in a week or two.

[badbob2121]

wow amazing job on the interior... turned out great!!

[S13AL]

Amazing interior , especially the glove box. I also like the z wheels, got me a set too.

[Skink]

Looks great.

My son and I are starting work on his 90... but don't think we'll get into anything like you've gotten. Inspirational, though.

Love the color (Been working at UPS for over 20 years - runs in my blood)

[xiaphin]

Thanks for the positive feedback guys. Only thing that's needed to complete it in my eyes is the digital climate control. Maybe this will quiet some of the brown interior skeptics.

I had a paint chip off my UPS drivers bumper color matched at the paint store. Its super close to the real thing. Anyway you could get the color code for the brown? Thinking about painting the car the grey/pewter color that the new UPS 18 wheelers have up on top of the cab. Pics don't do the z32 wheels justice, far better looking in person. Glad you are digging it. More updates soon.

Updated Specs - Waaaaaaay Overdue

[Skink]

that's the UPS Freight trucks...

I'll see what I can do.

[xiaphin]

Auto to manual conversion with the park/neutral switch jumpered.

Getting fuel just no spark.

Thought ignitor chip (Z32) was bad but tried my extra one and even robbed one off my Z that I know is good. Still no spark.

So I checked voltage, and ground on all 4 coilpack harnesses and it checks out. Also continuity from coilpack harness ground and ignitor chip.

TPS, CAS, Ignitor chip, MAF, fuses and relays all good.

Took CAS out and spun by hand and could hear EGI Relay click, all 4 injectors click, and hear ignitor clicking / buzzing but no spark. Had a coil pack out of valvecover with spark plug connected.

If I try to start car and have voltmeter probe in far right coilpack harness connector (signal wire) I'm not seeing any voltage or fluctuation in voltage. Doesnt the CAS send a signal in voltage to the coilpacks telling them to fire?

Havent checked with a spare coilpack. Hoping to find one I can borrow locally. Dont see how all four coilpacks would be bad though.

Anything I'm overlooking here other than checking a coilpack I know is good?

how are you using a z32 ignitor. z32 is for 6 cylinder and wont work. either use the stock sr ignitor or get a q45. they have 2, one for each cylinder bank

[badbob2121]

not true ^^....i believe to use a z32 ignitor you have to splice the wiring into 4 of the 6 postions on the z32 pigtail

its more difficult, but i know they have been used before...

[240life]

I have always run a z32 ignitor. Works perfect, and if a wire breaks you got two more you can use.

[xiaphin]

Z32 ignitors do work... had harness wired by wiring specialties... another user over at carolina nissans said he had same problem as me and turned out to be bad CAS.

[s13drifter88]

hmmmm, i didnt know you could use the z32 ignitor. i had been informed that it wouldnt work, sweet.

[S13AL]

Sounds like some crazy ecu problem. Any new pics of the car on the ground? If so please post

[xiaphin]

Highly unlikely an ecu problem, using new PowerFC with Dataloggit. Wis I had a stock ecu i could run codes with. When monitoring my sensors, fuel, and ign timing everything checks out except my ign. Value should be 20 at idle and i'm only seeing 4. Dont think CAS is functioning properly. Gonna order a new one today.

Dont have any pics with car on ground yet.
