I liked the staged approach your taking (I've still got the MAF), and the FSR kit edged out the PHR for me also. The BTI touch screen gauge looks useful also. I look forward to your progress.Hello everyone.
I have owned my MKIV Supra now somewhere around 3.5 years. I have only put about 4,000 miles on the car and have spent this time trying to get the car running and looking as close to new as possible.
Performance wise I have a 3" Megan down-pipe, 4" HKS Ti, K&N panel filter, fuel cut defender with patch harness, manual boost controller, GF210 springs, Southbound Stage 3 Endurance. All the fluids have been changed and the transmission leak was fixed with an o-ring replacement on the shifter rod. Car is also running 275/40/17 R888Rs on the rear.
The car is BPU on about 16-17psi and runs great. No CELs, just a bit of smoke at startup (valve seals). I recently just sold my swapped 13b rx8 and am looking for a new endeavor.
I have been reading all I can on what works and want some critique of my future plans to avoid some common mistakes.
My ultimate goals are to make 450-500 rwhp on 93 octane and eventually 700-750 rwhp on E85 for glory runs. I have picked these levels because it has been stated that once you past these horsepower levels its is pretty much impossible to hook on the streets. I also love the factory feel of the SB Endurance 3 clutch and it seems like once you get around these levels it may not hold the power.
My plan is to changeover to a single turbo in two stages to give me time to enjoy the lower horsepower level before cranking it up again.
Turbo Kit (with MAF provisions for factory ECU) - FSR, maybe PHR
FMIC (no BOV) - ETS 4"
Innovative SCG-1 (Boost Controller, Boost Gauge, AFR)
Full Fuel System (800 horsepower rated on E85)
Standalone ECU (ECUMaster Black, Pro EFI, Haltech 2500, etc.)
GSC S1 Cams, springs, tensioner, and valve stem seals
Probably Stage 1 this year, and Stage 2 next year. Who knows could be sooner/later.
I pretty much don't see a need to go with a tubular manifold setup since it doesn't seem to be necessary when you are below 800 wheel horsepower.
I have been pretty much been building and rebuilding the PHR and FSR kits over and over again to try and figure out which is the best. They both seem to be good quality and fitment, and both have positives and negatives.
I am leaning towards the FSR because the manifold seems to flow a bit better, they offer a 4" down-pipe, and I like the Turbosmart gate option. I don't like how it pushes the turbo so close to the frame rail, but you can't have everything. I know that BW turbos seem to not fit that manifold, but I have a divided S362SXE 0.91 AR with 3" v-band connection (no Marmon) that I would like to try and use as its already sitting on my shelf. If it doesn't fit, I will simply order a 6266, 6466, or 6766 (which ever will fit my horsepower best without putting to much pressure on the conrods). I would like to try and make a ETS 4" FMIC work with the kit if it fits, unless someone has a better FMIC suggestion for the FSR kit. Lastly, since I will be running the factory ECU/factory fuel system with the first stage, I plan on using the Innovative SCG-1 to monitor AFR and boost under WOT to make sure I don't go lean from pegging the meter, maxing injectors, or maxing the fuel pump. The electronic boost control feature will also let me dial in the right amount of boost for safety.
I don't want to get too deep into the Stage 2 items as that can be for another day, but would like to put my order in for the Stage 1 items in the next few weeks so I can start removing the factory twins.
If anyone has any constructive criticism on the parts/kits I am looking at, possible fitment issues, the way I am staging things, or things I may have missed entirely, please let me know as my experience is limited to rotaries and cam in block V8s.
