TrevMcRevs 924 Grp4 Rallye Build

Might as well consolidate some posts into 1 thread here...

So for some context I'll copy in my original Wanted & Found threads below, then carry on with progress.

 

It started with a search for a suitable a 924.

Not a minter. More so an ok driveable (or close) project car.  

Mechanicals more important than body or interior.

Not a faithful Group 4 replica. Or an actual competition rally car. I have a full blown Mitsubishi rally car if I want to compete again, this is more for a bit of back road fun and adventure. Think non-competitive "rallye/safari" style build.

Suspension jacked, rally tyres, light pod, mud flaps, half cage, maybe period Martini or Rothmans livery...

The vision for this would be a registered (full/club/historic?) car that I can take for a SMT and when you all take the tarmac twisties around the mountain, I hook a left, spear off up some gravel shire roads spraying rocks as I go slideways through the forest, and meet you out the other side of the range covered in mud and stone chips grinning ear to ear! 

Something that has a Porsche badge on it that you can drive anywhere with zero f*#$'s given.

I'd love to do it with a 911 but finding the right car at not silly money is eluding me...

I considered a 944, but kind of digging the basic-ness of the 924.  

I've always had a thing for the Underdog.

I get that some folk a gonna think this is daft but they are just going to have to....

Then thanks to a tip off from forum member @Jonathan in the What's for sale thread, I found the donor car.

An early 924 being a '77 build non-sunroof car.  And fitted with a rare optional Porsche 5spd snailshell box, as found in the Turbo, rather than the Audi based 4spd and later 5spds.  Mars Red with Black interior and Herringbone inserts.

It's an import.  From a place called Tasmania.  I hope it's as good as the Australian delivered ones...

I bought it sight unseen.  Nary even a PPI.  I figured at worst case scenario if it doesn't even ever turn up the most I can loose is a few grand!

The previous owner may or may not have had dreadlocks.  He could've been an outlaw.....or a dentist.  Maybe an outlaw dentist!

Could it have even once belonged to Tazzieman?

I planned to do unspeakable things to it.  She might just be too nice though....  

OR IS IT!

After transferring the big dollars to a random dude for a car I'd never seen in Tasmania, things then went very quiet...

Lots of dramas trying to organize transport...delay after delay...

I were starting think maybe I had done my dough...

Then he sends me this pic.

Could mean that it's being picked up, or for all I know it's an old photo of it getting dropped off when he bought it!  

I still can't get hold of the transport guy, so who knows!

She does get delivered after all! 

Now my 2 boys, they both love Porsches, as far as Billy is concerned if it aint a GT__RS pffftt! Don't bother.

But Jack lurves old cars - only old cars.  So when he got home from school he was all over it.

"Best car we've ever had" in his words...

And when ever his friends come over they go and play in it.

First mod I'd be doing is taking 4 inches outta the dildo shifter .....  silly seventies - did 924 owners have dinosaur arms?

22408-shift-knob-replacement-2000-nb-127

Jumping the timeline...but that was actually a job I did today funny enough!

That dildo had had a right good flogging, so much the knob was starting to tear off!

Earlier on, without really looking at the car I impulse bought a cheap rally style knob for it.

Not until I went to fit it I learned about the weird lever/knob set up on these...

You cant just put any old knob on as it's a flat rather than round lever, and the knob and boot are one.

And the stupid one I first bought came with about 5or 6 stick-on gear shift patterns - every thing BUT a dogleg 5 speed of course...

So I found this cnc machined billet aluminium short shifter from Ideola Garage. It reduces shift by about 50%.  And with all new bushes and no wear it already feels WAY better!

Now I just need to find a knob!  ( I don't like the one above....)

 I've got one of the golfball type knobs with big dimples from a VW Jetta in the 911 and daily van that Boys Own Garage sourced for me. Love it

Wouldn't that metal gear knob take the skin off your hand after baking outside on a hot summers day? 

Love the project Trev. Nothing better than a fun car you can thrash and not care if you hurt it :D

So maybe at this point you're thinking "Why the hell a 924?"

Well there are a bunch of combining factors that I managed to convince my brain that a 924 was a good idea...  I won't bore you with how I did that.

But just in case you think they have no place being a gravel rallye mobile, I'll share a few pics for inspiration.

So from Monte Carlo to African Safari to Around Australia, these cars have a history of spraying gravel.

One thing a Rallye Banger must have is the right wheels.  Being an NA 924 with the 4x108 stud pattern with a weird offset, I knew this would not be easy.  Most would convert to 944 5x130 and inherit the bigger brakes, rear discs, and way more wheel choices...  That would be too easy.  There's other ways around those things... it doesn't have to be bolt on Porsche stuff.  I've converted Escort rallycars to rear discs using all sorts of mixed-bag parts so I'll look at that later.

Back to wheels. Figuring I'd probably have to go with Miniltes as there are lot of sizes available...but in my research I found Peugeot & Citroen had same pattern and offset.  So that widened my search, and led me to a set of genuine old school refurbished Compomotive TH Rally wheels!   Must have.  They came with new Kumho road rubber, which I didn't really want.  These were a Gumtree find from a Peugeot 205 GTI in Qld.  I have piles of Michelin

 

gravel rally tyres to swap on. They could be a bit stale though....

Test fit time...

Now I need to get some red circular P O R S C H E MOTORSPORT decals made up for these.  Cross between Compomotive/OZ Racing and BBS Turbofan style.

I do have a vinyl cutter but the old pc that run it has long died and I don't think a modern mac can drive it.  I will have a go at resurrecting it because it will come in handy for plenty more things, if not I'll hit up forum sponsor Autografik...

or at the starting point with a failed alternator and fried battery :ph34r:

Will beef up the alternator and run an Odyssey battery.  That has always handled my Escorts and Lancer spotties without issue.  Though I did learn that the hard way in my first Escort I built as an 18 yo...

Here's that new shifter in. Haven't found a knob I really want yet...  

Maybe just a plain Alu sphere... or a Quaife nylon job... Or a 917 style wooden job... Or something custom... 

I do love these ones from Function First, but they are designed to thread onto their own sleeve that goes over the old flat style lever. And then integrate with the original boot, but i'm liking the idea of the exposed alloy lever and minimal boot, or no boot and a custom gate! 

Alu with red shift pattern or black with white shift pattern look great.

Wow! Very Ferrari...not very Porsche...but damn beautiful

It looks good in this 924!

To get a ferrari style gate to work it would have to be a long way up the gear stickso that the distance between say the 1-2 and 3-4 plane is far enough apart to be able to have a strong seperator between them.  The fact its a short shifter would accentuate the problem because the shifter isn't moving very far.

They have more place than a rallye 80's 911 cabriolet...
