Re: Sprint 6C build up

Hi Crank
For the rear windows, I take the trim off the bottom edge, inside and out. Undo the two screws at the front of the glass surround - And the one at the back! then its a wriggle to free the whole assembly up and forwards. If you still have a winder mechanism that needs to come off first as well......And yes I intend to seal mine shut as well on reassembly, but they wouldn't be able to go down anyway with the extra width of the V6 suspension strut towers at the back.

More Progress
Two more cutting disc plus some serious work with a hacksaw and a hammer and chisel and I now have a hole in the back of my Sprint.... ..
Now what can I put in there??

Re: Sprint 6C build up

A trial fitting of the 164 subframe highlights where the problems are - the sides and the front! Anyway I have decided that it will be a lot easier to cut off the front cross member ( it goes way too far forward in the cabin) and fit the two sides as separate units . Then I will provide suitable bracing and reinforcement .

Re: Sprint 6C build up

Watch those measurements!
I know I'd have at least 3 goes before the wheelbase was the same on both sides.
keep up the good work.

Re: Sprint 6C build up

Thanks for the comments guys!
Well the front of Sub frame is now cut off and the location seems to be getting closer. I will need to cut out the Sprint "window boxes" to get the proper separation of the strut towers.

Re: Sprint 6C build up

Well I couldn't resist having a trial fit!
.......and it's looking good but there is still LOTS of welding, bracing and support structures to put in place.

Re: Sprint 6C build up

looking good mate hope your going to have the biggest plexi-glass screen between the seats and that glorious engine so it can be seen and not just heard
bet you have to restrain yourself a bit from just getting the welder out now

Re: Sprint 6C build up

Looks like a huge job to get it aligned perfectly but that engine looks sooooo good in there.

Even wheels dont look to stick out too much

Good luck

Re: Sprint 6C build up

Hi Kev
Well I couldn't restrain myself and I've been busy welding!
I also want to see the engine and I had a plan...... (but not using Plexi-glass)
Now I've trialled it and it looks to be a cool idea - I've got a spare rear Sprint boot panel and so I'm using the rustiest one as the "Thermo-acoustic barrier". I think I can also get it to hinge forwards and upwards for engine access.
I've also now got some box section to support the rear structure and subframe.

Do you think you might re wire the de-mister sixnut.

Re: Sprint 6C build up

bit of room left over at the back, you going to create a small boot? guess the radiator is going at the front?

Re: Sprint 6C build up

Just realised how far forward the engine is

You could get a bigger boot in there than a GTV

Re: Sprint 6C build up

Looks great... and It's got rear steering !!
Lets see you hook that up somehow with the front to finally create an Alfa with a decent turning circle (handbrake turns aside).

I take the fuel tank is going up front ?

Re: Sprint 6C build up

Hi Craig
Sorry to disappoint but the rear steering will be locked! I don't know yet whether to replace the rack with a solid bar or just fit a locking plate to the splined shaft.
Yes I will be putting the petrol tank at the front - but I've got to take that engine out to put it in my other (engine-less) Sprint.
Pasc and Kev
Yes I will be having a useable boot and the 164 Radiator will go to the front - however I want to get a reasonable airflow through the engine bay, so will have to arrange suitable extra cooling holes and mesh at the rear (As per 6c pics I hope). I have started bracing around the back and now have a rolling 6C
I have also been looking at the possible linkage solutions to the gear change

Re: Sprint 6C build up

yes,lock the steering, but keep the adjustment of the steering rack to adjust the rear toe-in/toe-out. do the track rods unscrew from the main part of the steering rack? that would be handy leaving a foot or so of adjuster bar for each side, or just use the whole rack as you say and make a clamp to go over the splines. just using the track rods & ends would make a neater job though?
keep up the good work

Re: Sprint 6C build up

Hi Kev
I'm still not sure about the rack - locking it is easier but keeping the track rod ends and having a threaded linking bar will be lighter and more elegant. However I have been checking the gear change. The existing system runs to the centre of the back of the car (See pic 1). By taking out the selector rod and putting it in from the front it now runs up and out to the glove box! (see pic 2) But I happen to have saved the steering column from a 164..... and it happens to have a short double ended Universal jointed shaft Which Might ,just be able to transmit the required Twist and push pull motion from the 164 gear change - which I also happen to have saved. (See pic 3)

Re: Sprint 6C build up

hope the gears work out ok, probabaly the trickiest part of the install so long as you don't end up with a mirror effect, first in bottom right and top at bottom left might make things confusing
great progress made, keep it up

Re: Sprint 6C build up

That's a really good feature (having the gear selector accessible from both sides - I wonder if Alfa were considering possible mid-engine configurations all along?). It means that you won't have a reverse gearchange (not too hard to get used to, I used to have a car with a ZF 5-speed, first was left and back on a dog-leg, with the remaining gears in an H pattern, but with 2nd and 4th at the top).

The more I see of your engine fitment, the more I like it Sixnut - it just looks sooo right in there.

You're right - ditch the steering rack; replace it with some thick plates with multiple mounting holes around the optimum geometry for strut suspension and put Rose joints on the inboard end of the trackrods. That way you can dial in roll-understeer if you need it, as well as adjust the rear toe.

In my experience most production steering racks aren't mounted at the correct height to counter these types of steering effects anyway, as manufacturers can now rely on power steering to mask the kick-back.

Great progress! I'm looking forward to seeing more pictures of your development!

Lauren

Alfanauts are GO!!!

Re: Sprint 6C build up

Hi Spacenut
Well I've not quite ditched the steering rack, I've stripped it and used the rack itself together with parts off the mounting area of the housing so it is now lighter, neater and dimensionally the same as before.(pic 1)
I've also been working on the gearchange to extend the selector shaft forwards and attach it to the UJ shaft - however it will need to mount quite high up in front of the engine to reduce the angularity for the Push -Pull motion. This may well mean that I cannot use the Sprint tailgate as the glass comes down too far..... (pic 2)
Another job has been to add more structural supports - and yes I know my welding is like "pidgeon s..t" so I build in lots of redundancy! (pic 3)
