What you guys using on high powered rst's? The car is a 2.1zvh...

 

Motorcraft 701c or NGK BCR8ES

 

Anyone else??

 

Big turbo escort cosworth plugs for me, pp8's.....was advised to use these years ago and never had any issues whatsoever.

 

Are these different to Ford 071 cosworth plugs then?

 

Yes they are.....071's are cheaper though i think.

 

recomend both of them, had them in my car no issues with either!

 

I use NGK BCP7ES or BCP7EVX on mine.

 

701 replaced the 071

 

Other way round. The 071c replaced the 701c

 

this man is right and they're good enough for a decent level of tune, but for big money better ones are out there.

 

denso itv24 are really good

 

sorry just seen its a zvh not a zetec turbo

 

701's or ngk bcpr8es though i find the spark gets blown out on ngks

 

If you are doing a ZVH, listen to this fella-

 

They'll need re gapping, i gap'ed mine at 60.30 or 06.30 on the old fealers. never had missfire since, done the same again this time when they was blowing on boost, no problem now.

 

didnt think of that lol, dopey sod

 

Its the simple things people forget about, hay when someone else has a problem i advise them, when i have a problem my brain just totaly wipes out what i know

On sunday went over to a mates to finish off my RS Re-wire and sort the boost out, over boosting.

So once mine was sorted i moved it from the back to the front of his drive. we wanted to wash all the oil and hand marks from the S2 hes rebuilding, lets just say the car started and was fine yeasterday, just left it after it ran and then sunday it wouldnt fire up.

After going from one point to the other it wouldnt start to a point where he got rather stressed, left the battery on charge and stiped down the old fucked shell to fund parts for the new one.

he got stressed again as it wouldnt fire up, as he went kicking and swearing i removed the plugs, cleaned up some spair ones i had in the RS, re-gaped them and place them back in, shouted him over and told him to crank the fucker up, and bingo! Fired.

NGks dont always come gaped correctly, there not Gen plugs there after market ones.

if there blowing out just gap them a little smaller, like .30 or something and that should sort the missfire problem

 

Does it matter which ones out of these buddy? This surprised me as always thought motorcraft was the way to go with plugs...

 

i use motorcraft 071c's in my zvh, never had an issue, i checked gapping to, so all set to 0.7mm

 

^^ what power/ boost yours making mate?

 

Ones platanum, ones just standard. Find the one that works best in your engine?

I found the standard one started to go a little splutterly over 25psi but the platnum takes 29psi no problem from my GT30.

 

i've run 14 psi with them without problems, never had more than that out of car.
