Re: Race Escort Zetec SE (engine build)

Some DIY exhaust manifold bits.
The flange should arrive in few days.
Now I have the DIY exhaust manifold bits ordered so when I can't work on wiring I'll do the manifold.
Cant wait to get these two bits done... then its only plumping the fuel,oil and water lines.

Re: Race Escort Zetec SE (engine build)

where do you get so much citric acid from?

is it just a battery charger you use for providing the current?

From the local apotechary. Sold in 100g powder bags.
The bags cost approx. 2 € a piece. I use 2-3% solution so two to three bags for every 10 liters of water.

I use a car battery and a normal battery charger just to support the battery. Propably unnecessary tough.

The part you need to de-rust needs to be wired negative and the other misc. metal object you need in the bucket needs to be positive. Object wired positive will corrupt and disolve so do not use anything of value.

Make sure the two wired matals do not get in contact. This obviously will short circuit the battery and it could start a fire.

Safer way is to just use a stronger 3-4% solution with out current. Just takes longer. I prefer this one whenever I have enough time.

I bought 99% citric acid from local Agrimarket.
Pig farmers give it to pigs suffering from diarrhea
5 kilos of powder cost something near 20 euros.

Re: Race Escort Zetec SE (engine build)

thank you,

looking to dip some parts as sand/soda blasting is messy and can be damaging

also it is a very cheap way of stripping parts, would this disolve paint or would it jus tbe rust?

It certaily will remove any loose paint.

Re: Race Escort Zetec SE (engine build)

what would you recommend to clean up a pair of webers?

could i use a dip? or is it a case of some elbow grease and some wire wool?

Don't know the remedy for that one. Maybe a total disassemblying and some king or blasting.

Re: Race Escort Zetec SE (engine build)

That's my new exhaust manifold



The flange has not arrived yet. But when it does I'll have a go of some cutting and welding.

I was advised to do 800 or 900 mm long primary pipes. But I do not know what are these measurements based on.
Any thoughs? Anyone?

Got them from Martelius Exhaust from Finland.
www.martelius.com (also in english)

They were not too expensive 74 euros per set of eight.
These tubes are 41,5mm outer diameter with 1,5 mm wall thickness so 40mm inner dia. 180 degrees within 80mm bend.

38mm and 44,5mm outer dia tubes available too. Also available with tighter 180 deg. in 70mm bends.

Re: Race Escort Zetec SE (engine build)

41.5mm OD with 1.5mm thickness gives 38.5mm ID
always look forward to updates on this, i'm planning a zetec se conversion on my fiesta at some point.

Re: Race Escort Zetec SE (engine build)

great thread.
if you cant get citric acid you can use a carbonate of soda solution (as i have done in past).
to make carbonate of soda, first make a solution of bicarbonate of soda in a saucepan (3 table spoons from memory) any bicarb / baking soda from asda etc. then boil it. the bubbles coming off are 1 of the carbonates (carbon dioxide?) anyway it leaves a carbonate of soda solution which you mix into a large bucket of water and start the electrolysis with battery etc.

Good point!I was only assuming the wall thickness. I'll have to do some measuring.

Thanks for the compliments Kee. I'll try to keep the updates coming.

Thanks Alladin

My patience is running low with this project! I want to get it running allready!

But just need to keep my head cool and consentrate on the task at hand. There's still plenty to do.
