The biggest revelation from yesterday was the brakes.
For such a cheap and easy modification these R33 GTS twin piston jobbies are awsome!
Highly recommended.

Had a play with old mate Elliots wheels today.
His BBS wheels are pretty much exactly the same offset as what I am trying to do with my BBSs.

My wheels really changed the look of Elliots car.

So.. no miss at day at Marulan?

31GUN · **Posted:** Sat Jun 09, 2012 11:03 pm

Nup.
Have finally figured out the problem.
Dodgy plug on the ECU.
Car ran like a train all day.
Only problem was I forgot to wind the boost back up and it was only running 10psi.
It usually runs 15-17psi and comes on far more savagely.

Next round of mods concern making it go around corners better- so front end grip.
And trying to get rid of some lag which will initially mean an exhaust housing/dump pipe mod.

Phase 1 of my new* plan to take over the world.
Collect stuff.

Z32 AFM (thanks Mikey)

RCAs (Roll Centre Adjusters, thanks Garage7)

Adjustable LCAs (Lower Control Arms, thanks Junk Garage)

As it turns out I'll be going a slightly different route with the front suspension.
Won't need those roll centre adjusters after all.
Bugger!

The miss problem fixed.

Problem.

Fixed.

For some reason, I find the miss is the wire to injector #4.......which is on the connector the arrow points to.

Handling.
Part 1.

31GUN · **Posted:** Wed Jun 20, 2012 10:19 pm

The S13 rear coilovers have a 2 stud 8mm setup where the Skyline has a 3 stud 10mm.
So the top plate has to be redrilled to suit.

I am tapping the plate so the bolts will be captured and I won't need to be in 2 places at once.
I'm using a 10mm x 1.5mm pitch #2 tap instead of a #1 or taper tap. it works much better with the soft aluminium, with plenty of WD40 as a lubricant.

The set screws are 10x30 stainless steel with a spring washer and nut.

Suspension Part 1:- HSD rear coilovers.
First thing was to remove the Bilsteins.

Not much room here

Then, because these are S13 units, I had to redrill and tap the top hats.
Centres are 82mm

Mark out and drill.

Then tap

Then a small countersink so the set screw will tighten right up to the base of the top hat

Then index the bolt heads and grind a small amount off to clear the shock top

Perfect!

Top hat finished.

And into the car. Hmmm, this may be a bit low considering it's still on the stands.

And it is. Needs to go up about 10-15mm

Raised 12mm and the car is sitting pretty well perfect.

And before you start with "should have left it low Hooks" I hate the 'car's got worms' look.
Level is good.

Agreed.
On the level. :tu:

Did you use the s13 front setup did you?

31GUN · **Posted:** Mon Jun 25, 2012 12:20 pm

Not yet. Watch this space.

in my opinion If you want handling dont use them! i have just removed them from my dr30 the geometry is all wrong.. unless you fix the outer tie rod angle and the toe in on turns it will hamper your efforts.. its seems temping at first but seriously you will be better of to shorten your oe McPherson's weld a thread to them and put z31 koni's or such in its far better for the cars handling

just some advice having been there you seem handy with tools so you could make it work but suspension is what i do and i couldn't justify the mods needed over re installing the oe struts turned into adjustable's.

in the rear on the other hand = perfect haha

You need to use S13 or R32 rods and ends.
Here is an R31 Vs S13 comparison. You can see the different angle.

Or better still use these...

They fix any angle problem and go a fair way to fixing the bump steer also.
