ok im ordering some custom made pistons to my spec,, but they need the complete specs of the originals, so that they can make them to fit the conrods and stuff.., its for a 1.6 escort rs turbo.. has anyone got the complete specifications of a std 1600 rs turbo piston?

 

custom pistons are going to cost a fair amound,, do you think your design is going to be a marked improvement over others already on the market?

 

well what it is,, im ordering the pistons from abroad,, and they dont stock the 1600cvh engine specs or bores sizes ect.. so they need me to fill out a custom piston order form out but TBH i aint a clue how to fill it out and was hoping that someone could help me..

 

He doesnt mean custom pistons I suspect, he just means they will pikc out the nearest and then maybe skim a set for him or something.

If he is going to be designing the ringland height from the crown and the thickness of the rings etc, then I suspect its going to come out fucking shite if he needs to ask questions like that!

 

I know where there's a CVH bottom end already built and ready.

(so do you!! )

Save yourself the agro.

 

LOL...

yeah i do..lol..

but they dont do finance..

if i had the money id take it off ya but im lucky to have 2k lol

fooking mortgages!!!! £700pm

 

nah its a complete fresh set of pistons to my spec.. thats what i said above.. not skimmed or owt

 

"To your spec"

In what way?

Do you get to decide the distance between the groves, the shape of the bowl, the height of the ring pack from the crowen, the thickness of the crown from the bowl, the height of the pin in the piston, the thickness of the rings themself?

Seriously mate, if you do, thats a PROPERLY skilled job.

 

on the custom piston order for they ask for everything,, deck height,, bore stroke, engine capacity, size of the pin ect,, thats why i need to talk to someone that knows about this stuff, thats why i have asked for help ect.. otherwise i agree with you IT IS A "PROPERLY" SKILLED JOB,, i want to find someone that knows about this stuff and have a chat with them..

 

If you just copy the existing design, its not a "custom piston" is it though?
Its just a cheap knockoff foreign copy

To start altering any of the basic characteristics much, you need to be ordering 20 sets all slightly different and then building engines with each.

Honestly mate, just buy some off the shelf ones that are known to work!

Its just not the sort of thing you want to be fucking around with yourself when you clearly know nothing about it!

 

What company are you dealing with ? JE? Diamond?

 

Chip, it's not that easy. There really aren't very many decent Forged pistons on the market for the CVH.

The ones in my engine and the engine that we are selling were made by Ross Racing and were spec'd in full. OK, so they were loosely based on a standard piston, but only in so much as to get the approximate sizes, then the desired compression height and so on was decided from there.

That's a custom piston in my eyes and is pretty much what he is after.

That said, £2k for a complete bottom-end, built is a bargain IMO.

The pistons will cost around £600+, the rods were £700, that's £1300 already.

 

THATS WHY IM ASKING FOR HELP FROM SOMEONE THAT KNOWS ABOUT THIS STUFF OTHERWISE I WOULDNT HAVE POSTED...

ok i want a set of forged pistons from a certain reputable place ( who i have in mind ) with a comp ratio i want for my engine,, thats all i need but they say that they dont have the dimensions and stuff of the 1600cvh engine.. i will need to send in a custom order form or ship out a piston so they can get the dimensions off..

 

If it was someone like JE, they will just pluck an existing design off the shelf, unless its all a paper exercise to get round a copyright???

Sometimes they will "design" you a piston based on a spec sheet you supply, but basically just use an existing design they already have that belongs to someone else that matches that spec and change the CR by 0.1 or something, I know of examples of companies doing this in the past.

 

SEND THEM A PISTON THEN!

 

By the way, if you think im being awkward its cause im just trying to get to the truth of what you are actually making so I can help you!

"custom pistons to my spec" and "copy a standard piston and tweak the CR" are not even vaguely the same thing in my opinion!

 

CP mate
are you the guy who does flocking also??

 

ok read what christian has wrote above,, thats similar to what i am wanting to do..

yeah christian,, i could have put a deposit on the engine about 4weeks ago but then i took the car off road to restore it so now all that is nearly gone

 

That would be me!

 

Apologies for not replying sooner christian, I must have opened the page to reply before your reply was in it as I didnt see it!

If that is what he is wanting to do, then sending them a piston makes the most sense, and just tell them what he wants difference, which no doubt will be just the CR anyway????
