Re: Sprint 6C build up

Got a good days work in. Started on the nearside sill, cut out the old rotten sections and inserted my reinforcement box section. Welded it to the strong section at the base of the A pillar and along the top with some welds also along the bottom. The other, shorter box section, is at the rear in the inner sill. These will both weld into the 164 inner wing structure in the front of the rear inner wheel arch.
Then I got the new sill section welded in place.
I starteed on the rear wing then and fixed the ends, welded the cuts, plated the end behind the door, dressed the welds - and threw some filler on for good measure!

Re: Sprint 6C build up

Well I've put a bit more filler on the wing and took a closer look at the round hole in the C pillar where the extractor vent is fitted - it is rusted all round and what is there is largely filler so quite difficult to weld to! Anyway on checking with the 6C pictures there is no vent on them so I will do the same and plate over the area.
Then I went out to pick up, what will go in my other, red, engineless Sprint.........
For next year's thread!!!

Good work on the sill Philip. Was that a sill from Steve Parry? I got one today and the profile looks great

That looks like the 16v out of a 146

Has no distributor, its electronic coil pack and has throttle possition instead of switch !
You can run that without the inlet manifold ! Throttle bodies only
No flow meter either ! Only thing you need to find the ecu with the vacum hose coming out of it.

I've got some tips how you can make that engine fly with not a lot of money when you get to it Philip

Excellent engine recognition 16V! and your help next year will be much appreciated. I have not got the ECU with the engine so now I know what to look out for

Hi Philip - the vents are blocked because they cannot be used as cabin air extractors - because you now have an engine bay where the back seat used to be!

The logical place to site cabin air extractors would be on the roof, but this would make for a rather odd look, as the roof panel extends over the engine bay area the grilles would have to be in the middle.

My suggestion would be to disguise the extractor vents in the "B" pillars, which has been done before on some cars. There again, as long as you are happy to drive with the windows at least partly open all the time (not an issue for a "fun" car I suspect), you can choose not to bother.

The body/chassis unit is really coming along now! I love the way you've massaged the shape of the bodywork simply by locally splicing and plating the original metal. Sort of like dressmaking for grownups... in metal

Alfanauts are GO!!!

Re: Sprint 6C build up

Could you use the C pillar vents as part of an intake for the engine?

Re: Sprint 6C build up

Thanks for comments folks - I will plate up the C pillar holes (they are a long way from the engine inlet system so not thinking that way). I did wonder whether they could be used as extra air extraction for the engine bay but I think the louvres will be sufficient. I suspect that air from the cabin will go into the engine bay due to gaps around the mid bulkhead and glass rear (mid) screen - I can wind the windows down and I have a tilting sunroof.
Finally I was able to pick up my silencers. I will be cutting and tack welding them to the bends to get the layout right , then they will be stainless steel welded. That's one of the last unknowns sorted.
I did investigate a method to get a pair of central exhaust exits but the pipework would be very confined so I've opted for exits behind each wheel. (I didn't like the first real 6c's ovalled central twin pipe, so I'm going for the look of the second 6C with its separated tail pipes - see pic on post 20)

Re: Sprint 6C build up

these 2 should create a good back pressure for the engine !

what diameter is the pipework ?

I think the pipes are 1 3/4" ID, with a 2" hole in the flange

Re: Sprint 6C build up

Got a bit done tonight. Cut out the rear vent sections and welded in some new(!) sheet metal.
Then started detailed fitting of the silencers.

Re: Sprint 6C build up

Hi 16V - yes the sills are done, just about. Now I have that strength, I can take the windscreen out, rebuild the bottom corners and plate the A pillars. I also have the inner rear wheel arches to finish.
I am trying to get it ready to paint by the begining of June.

Re: Sprint 6C build up

paint job will be a pain in the backside

I have the same worries with my red sprint. I'll prep that myself though.

I've been thinking... how would you like to start collecting parts for your project with your enginless sprint ?
You need to find the following if you want to squeeze all power from that engine:

1 - you need to find the 16v front bit of the crossmember - has clearace for the lower cams

2 - the exhaust manifolts of the 16v as they are different in diameter and have different angles on the flanges

3 - the non catalyst ecu - and wiring
4- the bosch air flow meter
5 - an oil pump and dizzy
6 - radiator of the 16v 33 - the one you have is too small even for the 1.5
7 - a fuel pump and a gas meter that has a 12mm out pipe isntead of the standard 8mm on your sprint - otherwise you will hear your fuel pump humming
8. a trottle cable and trottle SWITCH no position

Then its 1 night's work to finish it

Re: Sprint 6C build up

I investigated pipework for the water yesterday. Initially thinking of drawn Aluminium tube but cannot get any locally so went to plan "b". On the 164 part of the system uses steel tube so I rang round steel stockholders and can get 38mm od (1 1/2") easily. Then I went to plan "c", and down to the local motor factors for two lengths of exhaust pipe! I did consider stainless, but it was such a pain cutting and fitting the silencers I am happy to use ordinary steel - I can also weld brackets to it if needed.
The exhaust system is now being welded by a specialist as it is stainless - hopefully ready on Tuesday.

Re: Sprint 6C build up

I have now joined the happy Sprint owners who have cracked their windscreens! Still I have a spare, so not a major problem - but I might ask an Autoglass fitter to install it when the time comes...
Anyway with the screen out I have started on repairing the bottom corner and "A" pillar on the passenger side - not quite as bad as the drivers side so good practice!
I have modified the Sud repair section to make it fit the Sprint

Re: Sprint 6C build up

Nothing wrong with steel coolant pipes if you use lots of anti-freeze (corrosion inhibiters) - I believe the FIAT X1/9 has steel water pipes.

I used 32mm copper pipe for my cooling system - it wasn't that expensive at the time, and I got all the bracket fixtures and angles from the DIY store and could solder it all myself.

Excellent progress as always Philip!

Re: Sprint 6C build up

I believe the MGF/TF used steel pipe too with a 50/50 water/longlife anti-freeze mix. I just "created" housing for my thermal fan switch from two k-series (rover 214's @ the scrappy) water rails by cutting the formed ends off them, mig-brazing them together to make a tube with 2x formed ends for the cut-in-half existing bottom hose to fit onto, then cut a hole in the side of it and mig-brazed a M22x1.5 nut from a radiator header (VX astra in this case) over the hole, screwed in the thermal switch from an Alfetta and hey-presto, correct temp. thermal switching of fan, no leaks, and no risk of hose slippy-offy due to formed ends on steel pipe .

My point being, (and Lauren may be able to answer this) will the hoses be able to slip, or worse, come off over time due to the pipes not having formed ends? or do the manufacturers of rads and water rails just do this to give them a better finnish to the end of the pipe?

In the dog house today BTW, so no Spring Alfa day

Keep your Alfa in good tune, Please drive harder and faster!!!!!!!
