I'm going to be on the mainland this weekend, and equipped with skyline for getting around.. I'll have to pay those yards a visit and gather parts. Thanks for mad tips! I should also get some spare fenders.... derp.

OOOOH, we were talking about DIY widebody done via cutting out the quarters and wheel arch and then laying it on top of a hacked up rear end but spacing it out..

Or better yet, cut out most of the body metal, then overlay with plexiglass in order to get transparent over fenders..

A video my buddy Cole threw together, small track day - just a few buddies sliding around. Car was weird, I hit a big tire and was running 4 bolt wheels (stock 240) on the front due to a failed 5 bolt adapter hub (Spinning studs... derp).

Oh yes.. And my car is currently stripped down to a shell and about to get rotisserie'd.

It looked good lol. Still need to take a drive over and watch. Ill probably ask Rasta if i can follow him out sometime (Maybe carry some spare tires or tools in my hatch for him).
I keep my car cleaner then my room
Fuck you then, I'll take my movies, box of chocolates, bottle of wine and chloroform somewhere else.

you should do half-cut overfenders :D
kind of like how AE86s used to do with their front fenders. that way you dont need to cut anything off except the wheel lips and just lay the extra fender over it.

Major tear down has begun...

First time the RB25 has been out since originally put in, now thanks to rad support modification I can actually pull it like a normal motor.



I've got a few ideas to stiffen up the chassis, many involve gussets, dimple dies, and braces...



Fuel cell will end up here, but this photo is just for the record (the decrepit state of my trunk.. ghastly)




The car is already almost completely gutted, everything forward of firewall is removed including suspension.. Rear subframe is being dropped this weekend, and then I will build my chassis rotisserie and spit roast the car.. :)

So far, the items that have made it onto the shortlist are:

-Tubbing out front fender wells (More caster, more angle)
-Tucking wire harness (so no rubbing)
-Deleting non essential circuitry in the main chassis harness
-Relocating the motor backwards roughly 5 inches
  -Major firewall modification
  -Possible new exhaust manifold required
-Install  fuel cell and clean up trunk
-Re-affix rear subframe (The last time this will be done.. Tired of ghetto fixes)
-Wire/flapper wheel the entire car, paint primer gray
-New downpipe
-Gauges! (I have been without a tach, temp gauge, oil pressure gauge for the better part of a year)

It's a long list, and it might not all get done this winter - but at least I now have shop space in which to work.. Oh, and theres a remote chance I may end up with megasquirt, and an RB26 - but that would spread my finances awfully thin..

Stay 'tuned'!

megasquirt for the win!
but be aware that fitting a 36-1 triggerwheel on a RB pulley is a fucking nightmare ;-)

We're going to get tricky with pulleys.. I have a machinist friend who is going to machine the ridge for the AC belt on the pulley to be a 36-1 toothed wheel.. No need to bolt anything to it, just make a bracket to hold the sensor. :S

cant wait to see your solution....
but honestly the RB pulley sucks pretty hard in my ghetto magnet test

;-) dont forget to use your ac bracket as mounting point for your sensor :-D

Picture dump! Haven't had a massive planning session, but soon I will be taking a flapper wheel and paint stripper to essentially the entire chassis.. Once stripped, rust repair is first on the list, then firewall modification and engine test fitting...

Exciting times. And I pose a question.. If a motor is 100% behind the front shock towers - does that technically make the car mid-engined?? 



Almost bare shell



Soon to be heavily modified firewall and fender wells.



She has not been out in years..



I'm investigating a wilwood pedal box, and relocating my accelerator pedal. Reason? Clean up the firewall, more room for turbo manifold, and possibly dual brake master cylinders.

Damn. Making quick progress. "100% behind the front shock towers"< Just what the fook are you up to??? You going back to black or staying white???

Brakes.

Good chance (budget depending) that I will be going with an inboard wilwood pedal box, and I want to know before hand exactly what I am getting myself into here..

The current system is a blend of S12, S13 and Z32 brake components. List as follows:

-S12 pedal assembly and 10" brake booster (Pedal ratio is: 5:1)
-240sx front calipers
-Z32 rear calipers (twin piston)
-S12 15/16" brake master cylinder


Z32 specs are as follows:

Master cylinder: 1"

300ZX front brakes:
- Four piston fixed caliper
- 40.45 piston diaeter
- 324mm diameter rotor
- 50mm wide pad

300ZX rear brakes:
- Two piston fixed caliper
- 38.1mm diameter piston
- 297mm diameter rotor
- 36.5mm wide pad

front brake bias  = 70.3%
rear brake bias = 29.7%


The problem at hand is that the wilwood brake setup offers a choice of master cylinders as well as pedal ratios. To further complicate matters the brake booster will also be deleted, which means that if I am to have brakes that function AT ALL I'll need to do some careful calculations.

The goal here is to correctly size the master cylinder (the smallest possible, without losing the ability to move enough fluid to actually compress the calipers). The pedal box I am looking at uses dual master cylinders with an optional balance bar. This particular one has a pedal ratio of 6.25:1

More to come on master selection, suspected braking torque levels, and clamping force.

the pedal assembly you are looking at is there enough room or will they move the assembly and effect the seating and steering wheel distance will it feel awkward. i was thinking of going with a NEAL floor mounted pedal assembly with hyd thottle. even thought of using a under floor pedal assembly but i would have to raise leg area floor 2" so the long narrow booster would not hang below frame rail keep us informed on what you do here i am really interested
