R3 Oil cooler Lines

[Padge]

Hi Guys, looking at changing my corroded oil lines on my R3. Have been looking at the Mishimoto kit on line and it states that the kit fits models from 04 to 11. I've read that the fixings are different between S1 and S2, so can anyone give me a definite answer please,before I buy them

[BigPete]

There different yes, make sure there for an R3

[Leck3000]

If i get the spec i'm sure i can make them at a better price with goodridge hose and fittings, can be swagged or reusable.

[warpc0il]

For the R3, the fittings onto the engine itself are proprietary, which is why only a couple of aftermarket brands (Racing Beat and Mishimoto) offer replacements.

The lines between the two coolers are the same as the S1.

Our esteemed Chairman has first-hand knowledge of this...

[Leck3000]

From what i can see from the Mishimoto and Racing Beat images there is nothing unusual about the fittings at all and i cannot see any reason why I wouldn't be able to replicate them.

As stated though, until i know the specification i cannot say this 100% but i would be very surprised if it is anything too unusual, just looks like metric adaptors.

[Leck3000]

Not sure how to tag someone but IIRC Goobie mentioned about a set of R3 hoses which he has spare. If he would be kind enough to supply the details or let me borrow them so I can create the spec that could be a simple solution to the question.

[ChrisHolmes]

Racing Beat are able to use industry standard connectors on their R3 lines, because they've made these adaptors

oh right. Both RB & MM pictures show M/M adaptors. 6M/M for R/B & 4M/M & 2Banjo adaptors for MM.

So do MM use these as well? Im slightly confused now.

[Leck3000]

Just to add as well. Having looked at the installation instructions from RB they use M/M adaptors into the engine, replacing the original banjo fitting which would have to be threaded. I also looked at the EPC but that wasnt very easy to understand the fitting types.

Is there a difference between Mk1 & Mk2 as the RB instructions reference the MK1 kit, is that perhaps where the misunderstanding lies?

[BigPete]

R3 has 2 studs for them to fix to and use the fitting above with o rings, lenghts are different as they both come from the front cover of the engine

[ChrisHolmes]

I have a Series 1 engine out of a car currently which has the Racing Beat Oil pipes fitted to it. As you have an R3 if you care to drive over to Cheltenham you could compare the differences.

Thanks Pete.

Well thats a bugger. I have a very good local engineering firm who i use to make a lot of bespoke items, if you would lend me your adaptor Warpcoil i could get it quoted.

As a rough estimate i reckon the hoses will be around half the price as the offerings from RB & MM, subject to confirming the spec, so having these made which wont be all that much could still offer a significant saving.

Is anyone aware of the p/n and availability of the original o-ring? it would be easier to use them if reasonable enough.

Thanks Chris.

As we seem to be going down this rabbit hole and i can assume there may be some interest in the S1 kit, i may ask to get the spec from yours so i can come up with the pricing for that as well since we're at it.

[Goobie]

I can take some detail picture's of my kit should that be of help. As mention, the block fixing is unique. I've kinda pre agreed first refusal on the sale of my R3 kit, so sending it out for parts to be cloned not ideal. Speaking of which, I could get the kit copy'd but I don't think that would go down well with Racing Beat or Clive, lol.

S1 kits have been done, the place that did it for the club last year now sells them on ebay.

Ok sure. If i'm treading on toes then i'm happy to back away quietly, just thought i would offer something with the potential of a significant saving to the club members.

Whilst typing the following your reply to Goobies post appeared, that’s the joy of writing a long post in an active topic!
Wording the following is complex intended to inform not to offend or dampen any enthusiasm to offer products that could save out members money and is written by me without a committee hat on, if there is a difference of course!

We live in a free market and the club treats all members and traders equally and it is important the club maintains the differential in status as traders make repeat sales creating profit and thus are commercial concerns the club requires Trader Membership to be in place for this.

As a benefit of membership people are allowed to offer items for sale fee free in the relevant threads where they are stripping their own car or have items new and used which are surplus to their requirements.

If such sales however are for other than no longer required or surplus items, ie; repeat sales of the same item, then this is classified as trading and as this thread is laying the ground work for repeat sales of oil pipes should you then proceed to actually manufacture and supply the pipes, or the TEIN and Mintex products previously offered by yourself at a saving, then the club would request that you upgrade to Trader Status.

The club itself cannot be seen to assist in promoting a “start up” Trader and so far nothing in this thread breeches any club guide lines and you clearly understand the sensitivities of bespoke parts such as the RB flanges being loaned out for copying.

I trust that you will understand the need for this policy and continue to progress the oil pipe kit supply possibility as detailed in the thread recognising that eventually starting the supply service will require Trader Status.

Totally understood Chris. I have been approaching these subjects with an element of caution as knowing that i may be approaching the bounds of private to trader and also treading on toes but my intention is only to help others out. My connections allow me significant discounts of which i have been offering on and purely restricted within the club. I have contemplated looking at the possibility of becoming a trader but not knowing the extent to which i can be of service to the members and how much i actually want to undertake has meant that it hasn't progressed anywhere at this time.

Perhaps a conversation may be in order with the powers that be to understand if it is something worthwhile or weather i should butt out.

For now i will leave this be.

I'm intrigued as to what actually holds that adapter (or the original lines) to the block if it's a couple of posts and a shaft with an o-ring? Are the shafts a zero-tolerance, interference fit with the holes in the adapter or is there some other securing mechanism that I can't see (or just missed)?
I'd contemplate having a furtle in my own engine bay for a looksee but it's currently peeing down, I'm supposed to be working and other such excuses.

[ChrisHolmes]

From the photo Bigpete posted it looks like the connection is a flange with an O ring seal on a spigot held down with two studs and nuts. The spigot will be a simple slip fit into the front cover.

[Ainmhidh]

Ah thanks - I couldn't see any thread on the studs, so that was the cause of my confusion!

[ChrisHolmes]

For the sake of info (and because I still haven't written up my experience with this job)..

That particular section is the bit with the proprietary fixing.

[ChrisHolmes]

Aha! two O rings on the OE connection. I wonder if there are two on the RB adaptor!

[Padge]

Thanks for the input guys. I've been looking at the oil cooler lines kit on Mishimoto uk website and it states that the kit is a direct replacement for the 04 to 08 model Rx8 only . Have now decided to go for Racing Beat kit
