OK, a few more updates...
Finally got off my slackass and got the Z up in the air to figure out a few things:
1) Why the hell it sits so high
2) Why the hell the suspension is so stiff
3) Why the hell the camber is all outta whack
4) How the hell I'm gonna run brake lines
5) Why the hell the interior hasn't crawled out of the closets and installed itself...
The suspension issue was first. The team at Tokico has been SO good to us - When I called them to get specs for their lowering springs for the S30, I described our issue. They mentioned it might have S130 springs or perches, and offered to send us a set of CORRECT lowering springs. We graciously accepted, and they arrived in record time.
The install on these isn't too bad - Drop the front strut from the engine bay, lower the control arm assembly, wriggle the spring out, replace and reinstall.
Once we threw the front springs in, it's clear that the previous springs were WAY wrong. It sits PERFECT now:
Suspension stiffness was likely a combination of issues: Too-tall springs with the wrong spring rate, and a function of the badly-blown KYB strut inserts... So, take everything back apart, and I'm off to order those!
That's cool, gives me some time to figure out how I'm gonna attack the brakes.
Toyota 4x4 front calipers, Nissan Maxima rear calipers... Surely I'm gonna need custom brake lines. I had an old tore-up line laying around from a Datsun 521 we parted out. It fit... Holy crap, this is awesome!!!!
As you can see, the rear caliper brake line port places the line at a weird angle, where it would actually hit the axle. So, Becky and I hit the local NAPA, bought a pair of short brake hardlines and a couple female-to-female adapters, and bent them up for the rear brakes:
Did I mention my wife can bend and install brake lines? Be jealous.
The soft lines mated up nicely, and will be fine for now - Eventually, she'll get braided SS lines once all the bugs are sorted out.
The interior had been bugging me... An old S30 interior isn't complex, but it's just weird. See, most cars have a full carpeted floorpan. The S30 tunnel is covered in diamond-pattern vinyl, the floorboards are covered by a pair of floor mats, and there's nothing on the firewall, under the seats, or behind the seats.
So, since we no longer have a heater core, a blower motor, or anything else, the firewall was exposed.
First order of business was to cover the entire floor in sound deadening. I like RAAM mat. It's actually the best bang for the buck that I've found, and it's easy to use.
Once that was done, I designed some pieces to cover the firewall, the top of the trans tunnel under the dash, the areas under the seats and behind the seats.
Then, the vinyl went in. Bleh. My least favorite part of the job, because it's SO easy to screw it up.
I had completely restored the seats almost two years ago, and they've been patiently awaiting re-installation.
Here's where she's at now... Hopefully the strut inserts will show up this week, and I get her back down on her wheels...
We're in the home stretch now... More to come, stay tuned!!!
(I will not be present for this step), get tires, and finish up the cosmetics.
