Interior with the cool new Recaro Pole Position (Pepita)

Brakes / Suspension all renewed to at least RS specifications

Very cool build list, love it and interested to follow along so please keep the updates coming. Is that Amazon green?

With regards to your G50/21 conversion, have you sourced the box and all the required parts? If so, do you need/have your sourced a C2 shift linkage housing? My understanding is this is only on the C2 manual, the C4 manual does not have it and i don't believe a C2 tip would have it. Just wondering where you sourced this from and what it is actually called?

Hey Mark,

congrats... how did you find the whole import process with all the added costs, etc.. was it still a win ($) rather than buying local? Would you recommend doing it?

Nice build. Love a good hot rod. 
My car has around the power you are after. Is awesome. 
This might come in handy if you haven’t already found it

Thank you for this. That shifter mount plate is I think, what I was chasing/after for a C4 to C2 conversion - great to know that it can still be purchased new.

Hi Gents,

The car (finally) cleared the painful Customs / Dept of Agriculture process and is in my hands today.

Build will commence in a couple of weeks, so patience is a virtue.

Transmission / Gearshift Mount - I believe Pelican have the part you are looking for.  Do the usual Renlist "Tip to Manual" search and you will find the reference.

Price - well lets say that if I halved the current Aussie listing prices (for Tip cars),  you may be awfully close to what I landed the car for.  A Tip on the global market is (max) a $70-80k car ... the aussie sellers are dreaming.  Another appeared last week @ $200k.

I have been thinking about this more and more lately... there was a US car recently that would have been landed in that price point you suggest, albeit LHD (obviously), however case in point... the local market vs row market for these 964's is just stupid as you suggest! 

Keen to watch this one. B)

Update:

Engine, Transmission, Suspension, Frunk are all now cleared out ready for the full re-paint (bare metal).

If all goes to plan she should end up a bit like a RUF RCT (narrow body - the rear wing and turbo).

Next post in about 2 weeks when she gets to the panel shop.

Sorry Gents for the lack of info !  I guess those of us that have undertaken such a project understand that (like a fine wine) these things take time.

COVID doesn't really help as I cannot go and visit the car and "push" a little.

Enough of those weak kneed excuses, car is now fully stripped - and I mean every nut & bolt, harness (even though we discussed leaving that in) and it looked like this:

OS Front View (naked).jpg

We were SO happy to really get inside the whole car and find a completely clean (zero rust) car with no chassis damage (photos available for those interested).

Over the last week the car was at a specialist metal fabricator to do a little Hot Rod surgery ... I attach below a couple of photos for viewing pleasure. 

I will leave your eagle eyes to pick up the alteration/s.  

I am VERY excited to have this classic RUF element included for this car !!

Looking good @mark2559 mate. Love the progress and pace.  Nice touch with the RUF look rain channels ‘gone’ too.  Proper euro hot rod touch.  Not sure about the 4” new wheels though. (I crack myself up sometimes).  
Please keep the updates rolling mate.

Nice. I was immediately wondering if you were going to do the rain channels when I started reading the topic. Glad you do -makes it really look so much better and closer to a RUF.  Good luck with the project and thanks for sharing progress!

Hey so umm, I don’t want to sound like a nannie no fun because I’m all about hot-rodding but I’ve got to ask. What are you planning to do to replace the structural stiffness the drip rails provide to the shell? 911 bodies flex a lot. Like really alot. The rails are doing quite a bit of heavy lifting.

The drip rails were in place because that was the easiest way for Porsche to assemble the panels (side + roof + rear quarter) and not have to "finish" the external appearance prior to paint.  The cross section of a 964 roof rail section is as per the attached photo.

2125086521_RoofSection(cut).thumb.png.006433618baa39ac0d8b9a94a97fb16b.png

The internal diagonal member is fully seam welded (providing a triangular support) to the roof edge/side panel.  There are plenty of reference cases (including RUF's own assessment) that document that the car is now more stiff with a full welded structure (rather than spot welded).

Additionally a 964 is a LOT more stiff than G Body (sorry to call this out) due to the dramatically larger sill structure + central transmission tunnel (for AWD) + much better front and rear subframes.

I am not at all concerned about torsional stiffness with this modification.

Just another brief comment on this subject.  I researched (in detail) this topic and quote directly from RUF as follows:

The roof of your Porsche is made up of three metal sheets. One over the roof, one over the rear fenders (the C-Pillar), and one along the side, which goes inside the car. These three plates were originally hammered together at the Porsche factory to form the rain gutters. They are not bound together in any other way. Through our gutter conversion, the area where the three pieces fold together is cut off, and then all three are welded together. Welding of the plates greatly increases their strength, and definitely makes the body much more stiff all around and along the roof line. Cutting, welding, and repainting are the only processes undergone in this conversion. No other parts or procedures need to be assembled or carried out.

Close up of the cut section is:

Now these 3 pieces are fully seam welded (base of A pillar to base of C pillar).  I am sure that I will not have a problem.

BTW - thanks for your interest and comments !  Keep them flowing !
