I am rebuilding my engine (2.0 zetec turbo) I am running std pistons at 16psi with no problem in over 30k miles. I was think about ceramic coating the std pistons, How would this help, Would it help at all??

xr3iturbo

just be as cheap to buy a set of low comps never herd of that getting done if u put a coating on top of the piston it will also raise the compression???

teflon coated pistons????

Avinitlarge

No idea how its done but to have a set of pistons done is cheaper than 1 forged piston

http://www.fireballcoatings.com/prices.html have a look at that mate $25 per piston f/kin hell thats cheap


so are you talking about getting pistons decked to lower compresion then coat them
sound s good to me mate

There's this bloke on ebay http://stores.ebay.co.uk/MD-PERFORMA...-RACE-COATINGS too (I've no idea if he's any good as I've not tried his stuff out)

Thats the one ive been looking at

I would be wary of this if you plan to run biggish power.

A good friend of mine had Ceramic coated pistons on his R34 GTR Skyline, the car was running big power. But a part of the ceramic flaked off of the piston at heated operating temp, under extreme load, and had a knock on effect of lots more chipping and flaking off.

The end result was a VERY badly scored and scratched bore, and the head needed reworked. But it was so deeply scored that it ended up costing a fortune.

Just thought it would be worth mentioning.

What would you call biggish power??

MichaelG

At the time i think he was running about 800+ bhp.

But i would guess any car could be subject to flaws in ceramics.

Avinitlarge

LOL, I was looking at 300bhp max, I need to find out more

ajjames

dont they use ceramic coating on wrc engines i looked into getting mine done on my 1800 peugeot 205 turbo hillclimb car when i re build the engine

Avinitlarge

So it is still unknow if it is a good thing to do???

Avinitlarge

Right, I finally got intouch with the bloke who does the coating. I asked him a few questions.

Would you require the piston being removed from the rod??

the piston can be coated without it being removed from the rod

If i decided to have my pistons done, Could I bring them to you as nottingham is only 30 miles from here??

yes you can deliver the parts to my workshop if you contact me first 01623 461892

Would I beable to run a higher C/R with a turbo if I used this coating??

yes the coat should allow a higher boost pressure or compression ratio to be run the main benifit in using a coating like this is to increase strenth of the piston to help protect against detonation

if u put a coating on top of the piston it will also raise the compression???

No the coating is designed to be applied very thin and will have no apprecible effect on the static comppression ratio

well i have never heard of this before, im well interested in it if it works, as i have machined down standard zetec pistons in my ZVH.

Avinitlarge

Ive found a bloke that does turbo conversions, He has looked ito it more than I have, He is turboing a BMW. The pistons have been skimmed and they a getting coated. Its all looking pretty good, Ive stripped my engine, Taking the pistons to be coated next week

Garage19

Let us know how you get on and post up some pics. I'm interested to see how they come out and last. Top work.

twinkle_2k86

defo keep me informed on how it goes, are you using the place off Ebay, or somewhere else??
