Our New Dr30. Our Old Prince Skyline Gt

[Bunky_r31]

Great build mate, good updates, shame its been tarnished by a bit of immaturity, doesn't this place have mods to delete that sort of crap?

More progress. Initially was going to do the bay and interior grey, but ended up getting some paint mixed up to the same colour as the outside so will be painting the inside to match the outside now.

[clubracer]

Designed some solid engine mounts which will also sit the engine 175mm further back. Bolts up to all the standard mounts. Yet to FEA them to see if they're strong enough but I'm sure they will be...

Will 3D print them for test fitting before making any final adjustments to the design. Might also lower then engine 50mm if possible. Will have to wait on the new dry sump to know how low I can go.

Pfft, who needs a firewall anyway

[clubracer]

Standard firewall will remain in place. Because the 30 originally had the 6, they mounted the 4 at the same forward point meaning a heap of room between the engine and firewall. Even the hole in the tunnel for the shifter is elongated and moving the box back 175mm wont even need a new hole cut.

I've been moving house, then moving house, then moving house.... yes three times in the space of two months.... but finally, it's over. My funds have been depleted but I'll start saving again to get this project finished! I did manage to buy a few goodies before the funds managed to make their way into a range of greedy and sneeky real estate agents and tradesmans' pockets though...

The Borg Warner EFR is the best off-the-shelf option for improved production, although not strictly heading down that route now, it's good for over 400hp and is T2 based so will have unreal response. So far I dont know anyone who has an EFR on an FJ20. With the compression at 9.5 it should make for a really sweet little engine. And with the standard gearbox behind hopefully it wont be too mean with a much more linear power delivery.

I also managed to pickup this GTS-R spec (I think!) diff cover which is finned, has extra capacity and come from the factory with blanked holes for cooler lines. This will get fitted once I have the diff freshened up.

Great turbo.

Let me know if you ever decide to part with that diff cover.

So there's been a pretty big change of plans... In time will be selling the suspension, steering and brakes. All of it brand new or rebuilt. About 8K worth.

We are going double wishbone front and rear with our own uprights and brake callipers, so the whole braking, suspension, wheels/tyres and steering setup will have to go. Everything is custom made so that it bolts up to factory. Is 8K just in parts, and all the man hours on design work...

[masTers]

That won't be everyones cup of tea, but I'm a fan.

Who did the design work?

[clubracer]

Yeah I know people will either love it or hate it, but at the end of the day I need to promote the business, and I want to do it with something that is a bit different that will stand out from the crowd. It'll be quite classic looking. No super modern wheels and crazy crazy aero, but clean lines and will actually do the shape justice.

Under the body is where it will all be happening though. Have completely bespoke and geometry optimised suspension with a double wishbone setup front and rear. Am designing some pretty trick rear uprights that keep the lower wishbone inline with the drive shaft so that the nice big aero tunnels don't get disturbed. We will also be mounting the callipers at the bottom of the uprights, further improving the C of G. Although there are lighter wheels around our own design will mean no restrictions. Mourning the front wheel cover will then be very easy for us. We are even contemplating covering the rear wheels completely and running carbon brake drums just the get the aero efficiency up. The brake calipers and uprights will be designed and manufactured by us and will be some pretty nice pieces of gear. We re already looking into using Titanium for the brake callipers, something that hasn't been done before (although there are some reasons behind this other than cost, which mind you has come down significantly).

We are also looking into carbon/titanium wishbones shaped for aero efficiency.

Still haven't decided on a transmission but after re-reading the WTAC rules it looks like we can run a rear mounted transaxle so I think that's the route we'll take. The FJ up front is a heavy engine, though we'll be doing our best to lighten as many components as possible as well as sitting it as far back and as low as possible.

We are waiting on a new 3D scanner to arrive so we can make a full 3D model of the car from cage to suspension (although still using the existing cage which is lovely anyway). We'll but removing from the front of the rear wheels tubs back, and from infant of the strut towers forward.

It's turned into a big budget project, but our design work costs nothing and we have the right partners to be able to make it into something of a showcase for us.

Stay tuned!

Looks insane. Hopefully we'll get to see it at wtac!

[clubracer]

It will be there in 2016.

Very cool! Loved reading this and good luck!

And also well done for keeping it on topic!

You mentioned you had someone come and do some of the major pieces of rust and weld it up again? I've just removed most of the rust in my car but there are a few major bits that I'd like some help with. Would you mind putting me in contact with them?

[Adzmax]

This is bloody awesome!!

[clubracer]

Wish I had more to report on this but business has taken over the life so the work on the car had ground to a halt.

One small update, my legend of a business partner plumbed up the brakes to the pedal box so next week the car will be rolling which will mean I can take it from the current premises to have some more cage and bodywork done.

Engine is currently stripped and about to get the bottom of the block scanned for the new dry sump system I've been working on. Will see the pump mounted directly to the sump. The sump will be CNC from a billet, and am also doing a billet timing cover so we can plumb the il feed nicely. Should look pretty sweet! Now I need to start saving for the CPC manifold to match all the other billet stuff on the engine!

Will post photos when I have them.

[masTers]

There is a CPC billet FJ20 intake manifold with throttle for sale in WA. I can find out if you are keen. Brand new, unused.

[clubracer]

The reassembly started today. Engine will be finished at the end of January so the plan is to have everything else ready to go. A long road ahead.

But today whilst installing the steering column and box I've realised I've lost the steering coupling (the bit between the column and steering box input spline). Anyone know if other datsun/ non power steer r30 fits or if anyone has one?

Got a steering coupler sorted. Finally the car will roll, brake and steer in a week. Now the fun stuff begins...
