Here are some shots(Before O2s) by @101duck from Simply Tuning of a RHD compatible top mount manifold and billet steering shaft needed for the dump pipe clearance.

There are a few other things on his plate at the moment but when its cleared the focus will be back on getting these ready for release:

It needs alot of work after getting the manifold.
I spent over 8k getting my single setup running after buying ducks manifold. Thats diy everything.

I think he was charging around 10k drive in drive out which I think is cheap considering my costs doing it myself.

Look him up in brisbane and give him a call or email. Simply tuning in Brisbane.

I will be selling my setup after I get some dyno numbers.
Only selling as I am putting a bigger turbo and moving everything to make it fit.

LFR isn't a kit and instead a drive in drive out conversion so unless you are in the UK pointless.

I have the walton kit and is beautiful... but expensive and has a habit of burning through o2s

Where does your wastegate dump pipe go?
Does it just have normal o2 bungs? Any extensions? I just doubled up the o2 sensor bung to get it out of direct flow of manifold pipe.

A properly setup and tuned twins are far better than a single and far less expensive on rhd but wont make the power as easily as a single if all you are doing is chasing numbers.

Dont get me wrong singles are great but have their issues too and when fault finding you better have a good tuner and mechanic ready to help you.

Unless you have deep pockets stick to twins and under 22psi on either 98 or e85 if you must for reliability sakes on a stock motor.

waste gate pipe goes out arch liner down in the corner of the right wheel arch.

Standard o2 bungs on it in the collector so a lot of heat and blown o2s. a couple of people have tried extenders/heat sinks but doesn't make a lot of difference tbh. mine is still in test phase so havnt killed any yet, but have a set of NTKs just in case.

If your after a RHD top mount I would say Dan's from Simply tuning is the best.

If you want the best bottom mount that's the one I helped build, I can vouch it has no 02 burning issues and has been solid for the last 2 years before the stock motor let go
at around 500+ rwk

Neither kit is cheap and will set you back more than the cost of the car.

If your going run a stock motor I suggest sticking to twins on 98 and around 350rwk, yes you can make more but I haven't seen the motors last long but for the odd handful.

At the end its your money/car and you can do what you wish.

Power figures are quoted on dyno dynamics aussie dynos which read anything 20 to 25% lower than USA dynos.

I’m RHD From the UK and looking into what ST kit is best, people say Walton burns o2 sensors but I’m hoping someone has a fix, somewhere

Just replied in you other thread. Stick with the Walton since you are in the UK and solve the O2 issues with the right heat sink setup. I have ADVs and a good tuner, no O2 issues at all.
