good to see fiat forum is still in good shape after all this time since i was last on here :)

came on to find the eper parts catalogue to look up part number for the exhaust manifold cowling which picks up hot air for the carb air intake.

this has been removed from my 1990 tipo formula because it had rusted very thin and had a hole in it. could be repaired maybe with some careful brazing but thats not for me to get involved with these days.

im in no great hurry to replace it but it would be good to get hold of a good one if not new.

i will also need some other bits to enable the thermostat controlled intake to work as it should, but want to get the cowling first so at least some hot air is being directed at the carb air intake.

i need internet explorer for the eper it would seem so will have to get that sorted then come back on. anyone interested in this subject?

i havent looked through posts on this yet, so apologies if ive missed help thats already on here.

the tipo formula model is very very rare, is it not? i didnt find anything of any substance about it when a googled awhile back. someone knows..

presto
 
thanks for the help. this is my third tipo, but unlike the others this one is not a wreck. so apart from replacing the brake pipes, hoses and anti-roll bar bushes i havent been too challenged with it and so didnt have a desperate need to come back onto the forum.

but if not for other reasons as well i would have been back on before now.

well who can work out what ive got just from the edition, which as i mentioned before is a "Formula". very very rare? i suspect there will be only one engine size involved.

yes this is a test, if i can get away with it!

a trifle surprised though that you, your good self, mentioned diesel when we are talking carburetter here.. so thatll be one eliminated then :D

and doesnt the 16 valve just have to be injection?

oh yes, i forgot, i did also have to replace the rubber mounting spacer under the weber and all those little leak prone vac pipes.. and the brake discs.. no welding necessary though. and no horrible load conscious valve to do battle with!!

that valve could be removed and i dont think mot would question its absence. after all the bracket for it was in place before the valve was introduced in i think 91 or 92 it was, as was the case with my 1990 "Formula".

thanks for the parts supplier link. i have a microfiche which covers tipo carb models but its a different format to the viewer i have (takes smaller microfiche film). but maybe i can get it in there under the lens and read off the numbers i need if the eper does not cover it.

its been off the road, garaged, since last august but nothing much needing doing for the mot, which i keep delaying. this is good because i then have to ride bike and get useful exercise during these restricted times.

at last mot there was slight imbalance between rear wheel braking which didnt have to go on an advisory. got to do some logical deduction on that and if handbrake does not share the same problem, then im not sure what could be causing it as there is no sign of fluid leakage onto brake shoes. but then that would affect handbrake balance also, so maybe the auto adjusters not quite right? not sure.

sorry, ive gone off topic a lot. i will start new threads if interest arises.

warmer weather this weekend so hope to move things along a bit more with car of the year 1989.
 
It will be a 4 cyl petrol of 139#cc

Fuel injection only happened because of catalytic converters.. in @1992

So yours tipo wont be too different from my old Ragata 1.3 and 1.5 ;)

My tipo's were 1929cc td's :)

Did have a 1989 1.4 briefly.. but felt underpowered :eek:
 
Just to confirm I was not trying to be picky re: engine etc. Yes I know you said carb. etc. but my comment was for general consumption for anyone looking for details about their car.

As it happens Petrol Tipo (non 16V) in years 1987 to 1993 came with 1100, 1370 and 1580cc engines.

Carburettor? You sure. Many, especially later years had Single Point Injection (SPI) and these had carb looking bodies. Check for a manual choke to confirm carb or SPI.

Your VIN number would point to the exact model you have.

Looking at the 1100 carb engine the cowling is called a conveyor. However there are TWO different part numbers determined by if you have Power Steering or Automatic Transmission.

If you have Power Steering and/or Auto Box then these I believe were always fitted to the 1370 and 1580 engines. For these engines the conveyor/cowling is a single/same part number for both engines.

I'm reluctant to quote any part number as without a VIN all sorts of errors could and do occur. In the Tipo (as with other Fiats of that era) there were quite a few "special"/"named" editions. I can tell you now the ePER has NO "Formula" listing in the main model selection process.

In the UK it was a 1.4 and there seem to be about 23 left, with only a few of those on the road. I have encountered the manifold shroud on my car, but I can't actually see it anywhere on Eper. I thought it was just for cars with SPI to increase the exhaust heat, but I may be wrong about that? The Formula in the UK did have injection.

I am interested that you say the load valve wasn't on earlier cars, as our Haynes manual circa 1989 doesn't mention it and Eper possibly suggests was fitted to cars from 91

I have a 1991 1.4 scrapped and it has no load valve from the factory whereas my scrapped 1992 1.7 diesel has the load valve fitted. Makes you wonder was it necessary at all!

I guess it is designed to improve adhesion when emergency braking AND lightly loaded. But as it corrodes and jams, does it continue to restrict fluid to the rear as if the car is lightly loaded, I guess it must fail that way round? Hence the back brake not showing sufficient effort at MOT.

There was legislation introduced that under all load conditions the front brakes had to lock the wheel rotation before the rear brakes locked- hence the load valve or valves built into rear wheel cylinders or very small pistons in rear wheel cylinders or decceleration valves.

Abs with electronic brake force distribution does the same job.

If a load valve is fitted and the load arm is not seized they normally function as intended.

I remember the Tipo Formula, it was the UK base version as I recall, 1.4 Carburettor from around 89 / 90, black plastic bumpers simple dash and plain flat wheel trips with thin vertical / radial slots.

I've got a Brava Formula which was a fully specced 2001 runout edition with spoliers foglights ABS etc.
