Hey All,

It's been a while since I've been able to update you all on the progress of my big single turbo upgrade on my RX7 FD3S.

If you would like to take a look at previous posts and videos you can use the below links.

Admittedly the progress has been rather slow due to time constraints and family commitments only allowing me an average of 3 hours per week, working on the tear down.

I ran into a major stumbling block over the last week or so, there is a turbo inlet pipe which connects to the rear turbo charger that has little to no wiggle room to remove. After a load of research I found that this is a common issue on RHD FD models due to the heater pipe being in the way and of course the vehicle firewall too.

I found that there were three options

• Support the engine and gearbox and loosen the mounts to lower the engine
• Remove brake boost setup to allow wiggle room
• Cut studs on rear turbocharger

You can all guess which option I went for. I lay down on the cold hard floor for over an hour with multiple hacksaw blades and cut through the two studs to allow the inlet pipe to be manipulated.

Once I was able to move the pipe off of the studs I had enough space to access the bolts on the rear section of the Efini Y pipe, once that was out I was able to remove it, eventually get through to getting the heat shields off of the downpipe and start loosening the bolts.

I am now at a point where I am an hour or two away from getting the twin turbo setup removed from the car.

In the interim, I've picked up the following for the build.

• XS Power TurboCharger 0.63 AR / 0.84(exhaust) AR
• HKS EVC Boost Controller
• Battery Relocation Wiring Kit
• OBX T4 Single Turbo Manifold (Waiting on arrival)
• AEM Wideband (Waiting on arrival)

There is still a whole shopping list of parts I am needing for the build but am doing things piece meal for the time being as I may change plans down the line but for the most part, new V mount intercooler setup (Once turbo is in I'll work on piping and space), datalogit for Apexi PFC, new fuel system (undecided) and any other supporting modifications.

This is an exciting yet scary build for me as I am way out of my comfort zone but cannot wait to see, feel and hear the big single turbo roar!

Here's two photos I took prior to removing the rear inlet pipe and the rear of the Efini Y Pipe.

I will keep you all posted on further progress, I'm hoping to drop the twin turbos sometime this week and start the clean and prep.

Thanks again for the support
