340R Colin's Honda Conversion

[roadboy]

I would prefer to run it in for him and make sure everything is checked then re checked before I let him loose.

This is a very wise move IMHO!

Hi

First post on here - I have been reading all the Honda conversion threads and trying to absorb as much as possible, much to my wife's annoyance.

Without wishing to take this off topic, would the RBC intake manifold fit in an S1 Elise using the Stark engine mounts or is the bulkhead different on the 340R? I think there was mention higher up of needing to mod the 340R but turned out not to be required, so wondered if that was the case with an S1 as well?

Cheers

It won't fit using the Stark Mounts im affraid.

I have an S1 with Standard Honda Conversion using the Stark mounts and there is only a few mm spare. I believe the 340R has the Motorsport Bulkhead so has more clearence but not 100% on this, all I know is that it fits.

You will need to modify the Bulkhead but as Dan says it isn't the end of the world. Just move the Centre piece forward

Oh and

and the RBC is bigger than the JDM, how much I don't know but It's 40 mm bigger than the PRB.

You use the Honda Clutch Cylinder with an adaptor pipe/fitting.

Link-up don't replace the cables but Stark Do. Why I don't know, best to ask them. Its a completly different Gearlinkage Assembly and Cables.

No LSD, I don't think its needed or don't have enough talent to notice the difference. Pretty sure even the serious racers don't use them maybe Dan/Scuffers have tried one ?

Fitted the Walbro (OEM Style ) Pump and won't do it again. It will do the job but not the nicest thing in the world. I would Run the standard pump to a swirl Pot then a 2nd Motorsport Fuel Pump (bosche or soemthing), easier to fit but more expensive.

You will need and regulator as well and I would fit a Motorsport Fuel Filter. Honda's regulator is in the pump so the Engines don't have one. I use the Alpha One (pictures above) and it works well.

Still think that my route was better.

Straight replacement uprated pump, good for 400 hp, fitted from the top by cutting a slot, out old, in new, then folding back again, around £220 and sold my old one for £100.

The Link-Up conversion does definitely replace the gear cables. They are completely different to the standard ones.

The Stark gear linkage etc. is pretty much a straight copy of the Link-Up one.

Tut, those pumps have their own issues and I certainly wouldn't be cutting a hole in the chassis to replace it. For ~£200 you could have a second pump and swirl pot which is definitely the way to go.

Well there you go, could have swore they were different. Who the hells was I looking at then ?

My Mistake,

Oh and with regards to LSDs, I am personally of the opinion that it's not necessary but if you are going to run one then the Quaife one is a much better bet than the Honda one.

Alan, the only difference I can see is that the Stark ones have cut-outs in the main linkage plate. And they use slightly different joints. The fundamental design and operation is identical.

It works really well so makes sense to copy it.
