Just seen a post about a product release and didn't want to post this on it.

There's a company in the UK, Walton Motorsports, who do a RHD ST kit for between £2,310 - £3,030. It's based off a DocRace manifold a guy in the UK bought then had modified to fit his RHD car. Just wanted to let guys from other RHD countries know in case none are available in your country and you want one.


A lot of guys are running them, I believe they're a straight forward fit with no additional work needed. It's the kit I'll be going for when I eventually go ST.

Hi, avoid this kit, everyone has terrible problems with burning 02 sensors. Every solution has been tried and failed. Moving the sensor bungs further back might help, but they won't do this for you. Has been known to kill brand new 02 sensors fitted at the strip after just a few runs!

Other kit is an optimised tubular hi-flow design for very high HP chasers.
Going back on my car with built motor now and may opt for a smaller turbo at some stage as it breaks things.

There are a number of people in the UK having success with this kit.. one lad is burning o2 sensors weekly another guy isn't..

The best way to run this kit is on Syvecs standalone as then you don't need to have o2s on the manifold. there are two lads running it this way no issues at all.

Inc syvecs/tuning and the kit is unobtanium for most as it becomes horribly expensive and worth more than the car, it would be better and cheaper to design a better manifold to stop burning out o2's.

If money is no issue then there is no problem but in reality it is.

Just out of curiosity how much is your Motive based kit?

coz lets be real here if someone is paying £6k+ for a single turbo kit and additional £4k-£5k inst out of the realms of possibility. We have UK guys here paying £10k for forge builds on 13 year old cars worth £6k

I think the major point here is if you want big power on this platform especially with a single turbo and RHD.. you have to pay to play.

Your motive kit was brilliant till you killed an engine, the walton kit is the best UK DIY option but you have to expect to kill o2s. if you are FBO and have £6k spare go to ledfoot and then get it tuned and supply your own boost control.

Unless someone can get the o2s out of the manifold you will always have issues... even the LHD American kits have issues with o2s there are threads on it here.

Its not 6k gbp for the walton kit its a lot more than that and he sourced a lot of the parts himself to finish the kit.

Its not my kit I just help with the design and the complete kit is around 13k gbp depending on exchange rate

The latest tubular manifold design will not burn o2's which is still expensive but its a complete solution and they'll will put you on with the tuner that
will tune your car perfectly to take all the guess work out of it.

All you will need is the mhd software, android tablet and access to a dyno or race track to log so he can tune your ecu.

This is a complete solution that will make in access of 800 hp or 1000 hp on a dynojet, its up to the individual how far they go and how much power they want.

The only part that's not supplied is the fuel system, ic and manifold as everybody has their own preference but if you need, they can point you in the right direction
if you want to do it right.

So im running the walton hot parts. The hot parts were £2.8k, turbo was£1.8k waste gate was £500 and I probably did about another £1k in additional bits. DIY install on my drive way and the car is running JB4 for boost control. So im at about £6k in parts.

leadfoot do their drive in, drive our at that price. So thats an amazing deal.

So in theory both options could get you a single RHD turbo car and then a syvecs stand alone with no o2 issues with some change to spare for the £13k your kit would cost

its all swings and round abouts really....

Walton say that their kit runs best on Syvecs and warned me many times that it was their recommended solution. Mine isn't a daily so if it burns o2s it burns o2s

but its worth noting the fastest N54 in the UK is running on the walton hot parts

You will also need ceramic coating and heat proofing plus it runs a screamer pipe which is a big no in most places.

Our kit is full stealth and will pass any emissions scrutineering, its all about flying under the radar.

Yeah the kit does not run jb4 and is tuned directly of the ecu as we found the jb4 to be unpredictable when the weather changes and needs
constant tinkering and we found that from a reliability stand point and most users lack of knowledge its not what we wanted and is another
cost saving.

This kit will work perfectly with a double barrel and at over 500rwk on e85 it did not run out of fuel or max the injectors out so you will break the
motor before you max this kit out on a stock motor.

The problem of running a syvecs and getting rid of your primary lambada sensors in each bank is you will loose the ability of seeing what each
individual bank is doing and what each bank of injectors is doing, so if you have issues with injector or injectors you wont see it until its to late.

There is no difference between the syvecs and factory ecu if its tuned properly in terms of power, no need the extra expense and keep it how the factory intended.

The tuner will evolve your tune and help you make changes at any time you need without the need of a workshop, the cost saving in tuning is
thousands of dollars alone.

This kit takes all the guess work right out of the build and is guaranteed to make the power as long as your motor can handle it.

Its a one stop solution to the rhd drive platform with extensive testing over a period of three years and 30k kms, cant say anybody else has done that which has no trade offs
and its a bottom mount so there is no heat issues at all, unlike most top mounts which tend to melt and burn everything around them and the fixes look unsightly.

We looked into doing a top mount but if you want to make real big power the problem is there is no room for a proper dump pipe like ours, we run a 4 inch dump to a full 4 inch exhaust
which is totally legal and passes any noise test and runs a cat but not supplied but can be, again every one has their own preference.

Why this kit costs so much is there was no short cuts or compromises taken when designing and building this kit, this kit will make more power than the n54 motor can take period.

But I understand people want to do things on the cheap and learn the hard way.

I agree with most of your post but this? Come on man, never a single thing melted in my engine bay or many other top mount ST n54s. I know you are pushing your product. What burns up on a RHD top mount ST that does not on a LHD?

Your kits seems to be by far the best RHD on the market.

Its not my kit, but helped develop it due to the substandard offerings on the market.

I've seen rocker cover,engine cover, paint on surrounding parts, wiring, inner guard liner and a deformed headlight housing in our 110f + summer days.

With this kit there is no need to worry about these things.

Once you start adding up the extra cost and trade offs it becomes clear that the top mount is not the answer for RHD but a cheap solution with more con's than pro's.

These con's can be fixed for sure at a substantial cost to do properly and when people say its cheaper it's misleading.

You are comparing a full solution vs a kit that needs a lot of supporting mods and a lot of extra expense not factored into the price of these kits.

If you sit down and do a parts and cost breakdown the two kits do not vary much in total cost and the top mount would not meet any emissions checks which
most people need but are willing to trade off for the sake of saving a little bit of money.

This kit is made in a way that will pass 99% of visual inspections and not attract further scrutiny unless the inspector has it in for you.

Do you mean fastest in the UK?

Because none of these run the Walton kit

The first N54 car in the 9s was a RHD ST car in Australia with the Simply Tuning top mount manifold.

I agree with this but surely using ADV sensors fixes that problem as they are specifically designed for that use (expensive I know)

ST kit with proper heat sinks is the first issue.
Second is getting your tuner to calibrate the O2s as V8Bait has done with my ADVs. Motiv do the same.
Dropping in ADVs or any other O2 wont just take care of burning out O2s.
Third issue is that too many try upgraded turbos or ST on the cheap.
Generally, you get what you pay for.
