RS stamped inlet

[loftylowe]

I've just bought an RS stamped inlet manifold, does this mean I don't need to match them because they are already bigger then the standard one I will be replacing!
I am matching the top inlets also and then painting before refitting

 

[Yellow Dave]

the RS is much better than standard, I had my RS manifolds done and TBH not a lot more material was removed.

 

[loftylowe]

An yeah? That's what I needed to know,thanks for the info!
Anyone else?
Also, when matching, do the ports in the actual head need enlarging too?

 

[coxxy]

no i think you just match the inlet manifold to the head. What will you be using to do this? i just got me some engineers blue to mark it up but not sure what tools to use for the best results

 

[loftylowe]

I will be using a dremmel and various grinding stones and sanding stones

Sorry to ask, but what's the difference between a stamped inlet and a non stamped? Where is the stamp please?

 

[montana]

are they not all stamped? i.e. with Renault Sport?

 

[welshname]

i thought that.

 

[focrs]

It's the lower one that is stamped on the underside of it. Big letters just above where the injectors go into it.

Its behind the fuel rail guard

 

[PP200t]

Is there something wrong if you don't have one? Are they rare or something?

 

[jon_r]

Not really, tended to be stamped on the later cars and the Cups.

 

[MarcB]

Would The Trophys have came with RS stamped ones ?

 

[PP200t]

Is there any gain to having one? I mean is it worth taking off my fuel rail guard to check?

 

[hilldawg172]

might aswell check its only two 10mm bolts. Made me smile when i discovered mine lol

 

[PP200t]

Ok cool, but is there any benefit? Can I gloat to others about it if so?? Lol

 

[hilldawg172]

Yeah theres a benefit, the match is better than the non stamped ones, meaning better airflow to the head.

 

[PP200t]

Nightmare to get it off, but I do have one!! Lol :rasp:

 

[montana]

interesting i didn't know this, i will have to have a peek at mine at soon point

 

[Alexjfinch]

I got one - dunno about the benefit though :/

 

[Yellow Dave]

don't need to take the guard off, although it does make it easier, use a mirror and torch and you'll soon see if you have, the two middle inlet tracks are stamped with a 2" 'R' and 'S'.

They were generally on all 182's, and quite a few of the later 172's. They flow much better than the standard inlets as the cast is not so restrictive. I have a set of upper and lower RS stamped inlets in the shed if anyone wants to buy them

Oooooh, i'll have a look later then. Mine is a late (2004) 172. It'll put a smile on my face if I have one tbf as I this was one of the things I wanted to mod

Knowing my luck I won't have one now!!!
