5 GT Turbo 11 years later silver bullet comes home

[Duncan Grier]

Early start, finished loading up trailer and car, cracking day for it

Quick stop check everything still nice and tight/secure so seemed wrong not to get a few cheeky pics

 

[Duncan Grier]

Always a pleasure to catch up with @Mark_L and successfully filled his unit with a 3rd Renault 5

Test fitted myself seated for roll bar on cage, good natter and time to drive home.

I might be a bit excited to what's coming next

 

[Duncan Grier]

Oh how gone cold turkey with no power hours or generally spamming you lot with lots of pictures and words yet small progress

While car safely with @Mark_L will probably be collecting end of January/February, have reserected long overdue Grier house DIY jobs

So more a keep alive update took a punt on DQ500 2wd adaptor plate and short shaft to see if it works on mine......bonus if so but if not know what I need to do no proven kit available ATM

Also when dropping off Mark had some wider OEM style arches we lightly positioned and had potential as a real option...Mark could not resist ....I mean kind enough to attach roughly to guage looks and while angles need some fine tuning certainly keeps the OEM GT Turbo era I am after v full fat Maxi kit which is not really what the car is.

Could not leave without pics......enjoy

Just leave it like that, with the duct tape.

While I continue house DIY in absence of the 5

Did pop in the garage to have a good look at adaptor plate and using the older VW 02M driveshaft flange bit purchased.

However while I need to do a final test on the gearbox when with it next, not fully convinced but may still be an option

While the older short shart has a retaining bolt on the 02M box, on the RS3 box no such option and uses a snap ring and of course transfer box also bolted to gearbox with stub spline for OEM driveshaft fitment.

It is 4mm short based on quick clamp/measure by eye.....could machine the adaptor to sit 4mm in if needed and also machine groove in short shaft splines but need to see how it sits in the box as outside of the spline connection the adaptor plate is just a normal seal and has not function for any lateral load of that makes sense

Interested in anyone's view

 

[Duncan Grier]

Below pic shows exploded view of transfer box and option B could be to design/fabricate needle bearings held mounted to block and use OEM driveshaft / and of course cover for exposed box section

And or get the shaft measured and custom size one from Dave Mac propshafts who normally do my custom shafts in the past

Half decent pic showing box spline

Something like this

Better pic for ref

If you didn do it that way how else can you do it?

Not much other option really.

3rd option is gearbox heart surgery and machine/change bits over to accept shaft as a 2wd housing.......but could get silly quick

When is it happening?

 

[Duncan Grier]

When is it happening?

Option 1 in play, hope to be with the box in the coming weeks and will conclude that one

I may be able to confirm a chunk of option 2 at the same time and even strip transfer box in advance

Option 3
Only in play of above fails, I can still mount engine/box and work out the best position based on driveshaft angles so plenty to do before entering this

Option 4
Could go DQ381 and update clutch pack if needed (2wd)......but a step back from my plan and have already gone wider to accept the DQ500 box choice

Option 4 for me would be a no-go. 4WD all the way here.

 

[Duncan Grier]

Well 4wd box yes but long sacked off 4wd option of engine and box up front, or looking at R8 box etc

But agree go with strongest 7 speed box off the shelf and should be within OEM limits even with engine breathing better

Ah , I missed the 4wd bit!

I think you need to go with your plan - the box that will cope when inside VW OEM spec.

 

[Duncan Grier]

So while things progressing nicely, reached a point I needed to go on a long road trip and have a day of hard graft with our resident metal fabrication god @Mark_L

Focus was on rear spaceframe final positioning and fine tweaks before tacking the beast of the engine and box final resting and mounting points

We had ambitious plans to get some more of the rear cage sections in along with some other jobs but don't underestimate the time lots of measuring, fine tweaking and designing solutions as you go consumes.....sure Mark will have wanted to kill me by midday when I decided the rear spaceframe wanted to go 20mm up and slight change to how the engine was going to sit

Turned out spot on and after 10 odd hours on it both done in, did get some time to test fit seat again for cage along with discussing rest of cage design

 

[Steve Swan]

Very nice..

 

[Big Steve - Raider]

It’s astounding!

 

[Brigsy]

Looks mega. Decent bit of progress
