MKIV Supra Single Turbo Conversion

[HellBringer]

I'm in the process of installing an old school RPS (yes, the clutch people) single turbo kit with an ITS 72mm DBB turbo & recirculated ITS wastegate. This same setup went 9.8 @ 153MPH with a 70 shot 8-9 years ago. 'Lag' should be very tolerable -- not much worse than the stockers in true-twin mode.





Stock twin removal was not difficult -- almost pleasant, actually... LOL

After a cumulative 5hrs the engine bay looks like this:




The manifold and turbo are just mocked up for fitment testing at this point. Everything is coming back out so I can give the engine a thorough detail. I've got a few small parts on order and I still need to install the TRD poly engine mounts. Due to work and upcoming travel it will probably be the weekend after next before it's completed.

Mods upon completion will be:

RPS T72 turbo kit
GReddy 3-Row FMIC
HKS Carbon Ti catback
Spec Twin-Disk clutch
TRD poly engine and tranny mounts
Blitz DSBC boost controller
HKS VPC w/ SAFCII
G-Force ECU w/ fuel, timing and 8k rev mods
2x HKS SSQ BOV
Trac-delete
EGR-delete
R1 Slotted Rotors
Hawk HPS pads

The only limiting factor at this point will be the fuel system. I'll be stuck at ~ 525RWHP until I pick a direction for fuel.

I'll update this thread as things progress.

damn that is a short list of performance mods for 500whp.

dear god...that gives me goosebumps just by looking at that lol. Looks sexy.

It dyno'd 444RWHP with the stock turbos. 525RWHP is the absolute max for the completely stock fuel system. The 72mm turbo is capable of an honest 800-850HP. With just a fuel system upgrade the car should easily be in the upper 600RWHP range. Cams and a few other minor odds and ends will put it near the 700RWHP range.

Interesting, subscribed for updates.

It always amazes me how much stock 2jgte engine internals can handle and be realiable its just unreal. But I´m still hard core rb fan ...

Well done, hellbringer. Should be a complete beast! So do you have any set goals as far as track times go? You going to go for 9's as well? Also, was the car that went 9.8 on that setup an auto or the 6 speed?
