hey man did you ever get this thing dynoed again once you had everything installed?
Not yet, I haven't gotten everything installed. I picked up an extremely rare used RMM supercharger kit. The kit is currently at my local speed shop but they are backed up and haven't had time to book me in yet. As there is next to no documentation on the installation of the kit, it'll take the shop a while to figure things out and fabricate along the way. A few months ago, I had a lower mile 1UZ engine swapped into my car. My car has 250k miles on it and I swapped a 70k mile engine from a local wrecked low mile GS400. The RMM supercharger will do well with the low mile engine. It runs really well and pulls harder than my old engine.
Everything is good. I don't track or race it, I daily drive it around the city. The air suspension is great, I can air up and ride at a normal ride height without scraping over speed bumps and driveway entrances but slam it when I park or want to take photos. I had a slight leak on the drive side airline due to me not using enough teflon tape on the threads but I fixed that and the entire system is air tight with no loss in PSI.
One thing I should have done was install height sensors. PSI in the bags don't always correlate to a certain ride height so I could be at 80 PSI per bag and really low or it could be a 2" fender gap and I never know until I get out and look. With height sensors, it doesn't care about PSI and just adjust pressure to to height. I'll be adding that feature later on this year.
I could see air suspension being a gigantic headache if it wasn't installed properly, chasing air leaks and electrical gremlins everywhere but if done right, it'll give you the best of both worlds (looks and performance)
I never fully committed to the S9 widebody and only went with the rear duckbill trunk. I kinda wished the fenders were weld in but maybe one day I'll spend the money lol. I through it all into the motor lol
A few years later, I think its time to update this build thread
RMM Supercharger is installed. Dyno'ed at 348.5WHP with the automatic transmission
Added an equally rare RMM Strut Bar. Polished, of course
Also manual swapped with a Nissan CD009 transmission and a SerialNine shifter. If there was ever a car that should come in a manual transmission, it should be a Japanese car with a V8.
Very big progress. Forced induction and a manual swap. Great work! I am finally done with my FI and CD swap as well. What adapter kit and clutch did you use?
Fisch Racing UZ to CD adaptor and a Heat Lightning Shop Clutch kit for the GS. It all works together well.
I had to go from the 3.76 mk4 Supra gearing back to the 3.23 stock GS400 gearing with the CD. At 3.76, first gear was not usable. Much better with the 3.23 gears. I kept the Torsen LDS tho.
I ran into the same thing. My factory 3.92s are insane with the CD series gearing. I already picked up a 3.26 GS400 diff and planning to swap the ring/pinion into mine soon. The Fisch unit is very nice, looks like Serialnine and them planned theirs together. I have the Collin's kit because it was a steal used. But those are definitely the highest quality out there. Took a hard look at the HLSS interior mount clutch pedal/master too, but again. My kit came with everything used, so drilled the firewall for the IS300 pedal. Great work on your build! Seems to be going well!
I try not to think about it, but you're probably not far off. 10k a year for the last 5 years.
This year, I'll need to relocate the battery to the trunk, relocate the air intake to where the battery is, rebuild the Vortech supercharger and potentially add more boost.

Sounds like a vocation. A life's work. But it must bring you a lot of joy. Keep it up!
