Re: Sprint 6C build up

I've just read from page 1 - 10 and have enjoyed every post... what a cracking project sixnut.

I wish i had half the talent of some of you folks taking on these mammoth projects.

Oh well i'm still in the throws of building my garage, these threads just make me grin at what I may be tinkering with once i have a roof over my head

Keep up the good work, I'm hooked on seeing the finished 6c

Thanks 166V6
My progress has slowed a bit recently as work is getting in the way! I have a window of opportunity next weekend though, so I'm tidying up in the garage to make the most of it.

Re: Sprint 6C build up

Sixnut, I think you might be getting a cult following ... I too was pointed in the direction of this thread by Pud237 when I suggested the idea of taking a GTV and putting the engine in the back ... which looking at what you've been up to actually looks feasible (on the assumption that I have the time/money to do it of course!!!), I would love to make mine 4 wheel drive, but I think that adds a whole new level of complexity (unless has been suggested I leave the engine in the front and just add another one to the back and link the ECU's together somehow) ...

... I have one question for you though, from what I can tell you've taken the whole sub-frame, engine, gearbox, transmission etc from the front rotated it round 180deg and put it in the back ... so how have you managed to get around the fact that reverse will now be forward and you'll now have 5 reverse gears???

engine /gearbox still facing the same way
he had to manufacture (very ingeniously ) the gear linkage to come forward , what would have been out the front of the radiater on the 164
sorry for answering that one for you sixnut

and, yes, it does have a big following

Re: Sprint 6C build up

Thanks Kev!
And to answer another part of 156Chris's post (And his 156 picture) I did hear of a newly designed tractor that ended up with 5 reverse gears and one forward because the Diff design was for clockwise rotation and the gearbox design outputted Anticlockwise
Another, hinted at, aspect of the build is that cost has been a major factor. It is, very much, being built on a miniscule budget (those of a nervous disposition read no further......about £750 so far.......)

Re: Sprint 6C build up

Grrrrr - a window of opportunity! but today was one of those frustrating days when Everything messes up. Simple ten minute "drill out two pop rivets and replace aluminium bracket" ends up taking an hour and a half!!!
My idea about brake calipers and hand brakes from the rear of the 164 onto the (Ex) front hubs is not straightforward so needs rethinking......
But I did get more welding done around the back and am slowly getting a part of an inner wheel arch installed. Will post some pics tomorrow

had plenty of those days mate
the way i see it there are only so many jobs to do, and even allowing for the 'fix 2 jobs find one more' syndrome then jobs are still getting ticked off the list
keep at it, one day we will have a 'mad restoration' get together day

Re: Sprint 6C build up

That's a very usefully sized boot you've got there Sixnut

Handbrake calipers are always a bit of a nightmare - but seeing as legislation has relaxed a bit over the use of hydraulic parking brakes (I think the authorities had to give way because Citroen were using them), have you considered using a handbrake with a hydraulic cylinder and locking one circuit?

In spite of it being a messed up day, you've still made plenty of progress!

Re: Sprint 6C build up

Hi Lauren
Yes I will be considering a hydraulic option - I used to use a "Line - lock" when I was drag racing and I think there was a hydraulic hand brake on the "Rally Design" website that Alfa 302 linked to earlier on this thread. Hopefully a better "tinkering" day tomorrow!

Re: Sprint 6C build up

Another mixed day but I've welded the front reinforcements to link the inner wings to the door pillars. But I've also had a closer look at my 164 rear calipers and I think that I will be able to use them with a fairly straight forward adapter plate - so I've run the cables and sorted where the hand brake fits!

Re: Sprint 6C build up

Hydraulic handbrakes.
A friend of mine has had one on his Minari (Alfasud based) for about 5 years without any MoT problems. I think he used the Rally Design parts. Apart from removing the need for cables etc, the hydraulic set-up is a much more effective handbrake than the standard Alfasud calipers.

Re: Sprint 6C build up

Hi Mark
I have looked at the Rally Design parts and they will be my "Fall back" position - I will adapt the 164 parts and see how they perform - certainly the 164 handbrake worked well and in the much lighter 6C should prove better than the original sud/sprint system??

Re: Sprint 6C build up

I have now sorted out the design of my brake calliper adaptor plate but the favour I was hoping to call in, to machine them, has disappeared - last heard of in Holland!
So it looks like a few hours with the hacksaw. Plus the only way to get them out of my small piece of 1/4" steel bar is with them interlaced.....hence even harder to cut out

Pics attached of work with hacksaw!
Card template to get the outline shape, then aluminium sheet as a mock up,(pic 1) then the 1/4" steel,(pic 2) As the caliper is only located by the two 8mm bolts on the sliding pins, the plate is over-engineered but better safe than sorry! More Pics When my 10MB quota is upped!??

Re: Sprint 6C build up

limit now upped - Thanks AO
pics of plate being cut and initial installation - obviously I will be tidying it up but it solves the brake problems. It reduces the (164)braking force - needed because of weight transfer Away from the new rear position. It increases the amount of rear braking compared to the original Sprint spec - possible due to the increased rear weight. It provides a better handbrake than the original Sprint
Whilst that is the theory, once it is plumbed in and the car up and running, I shall be checking All the systems from very low speeds initially and only gradually exploring the performance "envelope"

Well I've just had time to work on the other calliper bracket and start on getting the handbrake cables sorted.

nice work mate, bet you got through a few hack saw blades
should have a decent handbrake though

Thanks Kev!
- didn't break a blade - but it's now very blunt and I feel that I've got Popeye muscles on my right arm!!
Both calliper brackets are now finished and mounted so attention has moved to the inside, The handbrake handle bolts onto two existing holes and I've reversed the outer cable end bracket. That has still left me with a gap, so I've taken the compensating pulley wheel out and I will make a couple of extension plates.

Re: Sprint 6C build up

nice work mate, all coming together nicely
is the adjuster for the cable under the lever? can't remember from my sprint, but it looks to be there on the pic if not could you make an adjustable link to go between the pulley and the lever?

Well that's another job done - two simple plates cut, holes drilled and now I've got a connected Handbrake (Kev the adjuster is still there under the handbrake handle) - except I cannot find the three other brake pads.......dohhh

Re: Sprint 6C build up

Further progress in as much as the handbrake is now complete and mounted with extra holes drilled and bolted. I have put temporary disc pads in place but I now need some worn 164 pads because the rear callipers have less gap than the fronts had (I've put a wanted ad up and in the 164 tech forum).
I have also made a front mount for the gear change rods and am now modifying the 164 centre console to cover them.
