The holy grail: Tamiya Porsche 959 4WD restoration thread
 
1 Attachment(s)
Hi,

this is my latest Tamiya restoration project (one of too many going on at the moment! [sm=drowning.gif]), but it's very special to me. So I wanted to share it with you.

It is Tamiyas 59th model, first released in Oct. 1986: #58059 Tamiya Porsche 959 4WD
Back then it was a technological dream which I drooled about, but never could have afforded. So it stayed a dream until today, when the postman left a decent sized package for me!

The car is a very unique design in a rather small 1/12 scale (pretty unusual for a car like that), but it was packed with everything you could ask for in the mid 80's.
It has shaft driven full time 4WD, reservoir'd aluminium oil shocks and the legendary RX-540VZ Technigold motor as standard. It was crazy fast back then, which usually caused some wear and tear on the cars.
The body is a highly detailed lexan shell, with working headlights and a nice rally-theme interior. The body is extremely fragile and not really UV-stable, so not many original bodies survived. Thats why spare bodies are super rare and insanely expensive!

Here's what it looked like in the Tamiya cataloge back then:

This is right up there as one of Tamiya's holy grails! The title of the thread does not do this project justice.. (joke) :D

Will be watching for sure!!

So now to my car.
I got it off the bay for so cheap, I couldn't actually belive! The seller got this car from the widow of a passed away friend, and had no clue about it. So it ended up listed wrong.
It looked good on the pics and the rare Technigold motor was there, so I thought why not!

So today I got it and I'm rather pleased with it. It even came with the original box! The body is in one piece, with all the little details like mirror, exhaust, interior, etc. and no cracks!!!
The only thing is the old paint flaking off and the decals are wrinkled and lifting. But thats o.k., since I have a later model with the censored 'Racing' decals. I'm going to get a fresh set of earlier 'Rothmans' decals and repaint the body.
There are slicks mounted (it came standard with those slicks on spare wheels for on road use!), but the original rally tires are missing. I will get them too.

Here she is:

I built a 959 in my days.. (for a LHS customer) It was way cool... advanced beyond its time! (This kit came out in the late 80s.. that's 20+ yrs ago!! [X(] )

The chassis:

The condition of the chassis approves it hasn't been through the hell many of its brothers have suffered. This one actally is in a great condition!
The only thing I figured missing so far is the original MSC incl. resistor. But instead there is a trusty (but not contemporary) TEU-101 ESC!
There is some hot glue on a battery holder, need to take a closer look at that. Strangely, the tires have no cracks. I never had that on a car this old before!
I'm not sure if I should open the diffs, as they turn really well and the dogbones show nearly no wear. Maybe only a good clean for the chassis and some fresh oil for the shocks. We'll see.

Here are some pics of the chassis:

I think you should disassemble the whole car and then do a build thread so I can re-live my childhood.. (joke) :D

Looks to be in good condition for sure! I'd still open up the gearbox and do a clean (motor spray / degreaser / etc.) and re-lube.. and possibly change out bearings that's worn down.. !!

Dante77 07-22-2008 02:34 PM

RE: The holy grail: Tamiya Porsche 959 4WD restoration thread
 

Sweet, so maybe you can provide some inside information! Did it have ball bearings as standard? I don't have a manual yet, so I can't tell. [:o]

I don't remember as I was only building it for the LHS (I love building RCs, ha!) for one of its customers. So it was not my own. I believe it came w/ some, but not full BB...

This is what I hope to achieve: A nicely restored shell. Note the correct tires. (Thanks, moosey!)

Looking at this pic, I think I'll ditch that front bumper. I don't think I'm going to run her anyway!

Does anyone at TamiyaClub make re-pro shell and decals?!

Dante77 07-22-2008 02:49 PM

RE: The holy grail: Tamiya Porsche 959 4WD restoration thread
 

Yes, Kamtec (UK) makes a repro shell, not sure about the decals, though. But I want originals anyay.

I think you should run it... I want to see some action shots of this bad boy!! (but yeah, don't abuse it like you do to your LB... hee hee.. !)

RE: The holy grail: Tamiya Porsche 959 4WD restoration thread
 

We make a deal: I'm going to run it, when you run your Wild One! :D

This is it's twin brother, #58064 Tamiya Toyota Celica Gr.B Rally Special

It features the same chassis, but with two upgrades:

- front stabilizer set
- center differential

Maybe I'll get these upgrades , too.

Whoops, typo! ;)
The technigold is not a screamer (around 19.000 rpm), but it has lots of torque. Geared right its really quick!
