New supra 650-700hp suggestion build

[vac131]

Hi everyone, I bought a 2025 black manual supra brand new back in April. My goal right now is to tune it to street and occasionally track. I’ve ordered a bunch of parts already that’s on the way. My goal is to reach 650-700hp , here is a list of what I’m getting, I would just like to know what people think of this setup and if I should change anything.


-Femto full bench unlock
-MHD+ platform
-PTB clutch standard dual mass flywheel organic + sinster
-valvetronic full titanium exhaust
-active autowerke catted GESI downpipe
-koyo auxiliary radiators
-CSF heat exchanger
-AMS radiator
-do88 intake manifold MERA
-RK titanium charge pipe
-DAW 6769 6 port turbo
-MST cold air intake v3
-Dorch gen3 HPFP
-Dorch flex fuel ECA kit
-PFS LPFP



-VR forged D-03 satin bronze rims
19x9.5 ET22
19x10.5 ET40
-PS4S Michelin
265/35/19 front
305/30/19 rear
-HKS hipermax S suspension
-Eibach front and rear sway bars


I am planning on ordering
-6x Injector dynamics 1050x port injection
-motiv reflex+
-radium dual catch cans


Should I order these
-verus engineering transmission oil cooler
-metal oil housing

- radiator/ hear exchanger same thing
- don't need a HPFP if you're going PI
- verus doesn't make a trans cooler. Maybe you mean oil cooler? Always a good buy on practically any car
- 6769 is overkill for a 700 build

-Heat exchanger and front radiator is two different parts isn’t it?
-And yes sorry verus is the oil cooler
-oh weird, the person that’s helping me building this says I need a HPFP
-daw6769 I just like how I can increase the HP in the future if I like to

For the daw676, I know it meant for higher Hp build, but I hear its performance is really good. I just don’t want to kill this car so fast bringing it up to 900hp range lol

I’m running my build through chat GPT as well, it’s saying I should get all 4 radiators upgraded, if I want to have a safe build

All that power is useless without proper meat. Get some better tires in the rear.

Best advice I can give is talk to a tuner who's familiar with the B58 and not a LLM that's capable of hallucinating.

Get axles. There's been plenty of stock turbo users on ethanol tunes who have snapped the OEM axles at the drag strip. Driveshaft probably isn't a bad idea either if you do plan to hit the strip often. Driveshaft Loop as well as some strips require it these days. (Not sure if this is different for Manual Supra's, but at that power it's better to be safe than sorry.)

You also 100% need better tires than PS4S's for that power. I spin PS4S's on the street all the time with a catless downpipe and JB4 E40 tune (maybe 440-450 WHP) - Go for something stickier.

I was thinking of getting another set of tires just for track, but current setup for tires is just for street driving, but what tires would you recommend? I was thinking getting the cup2 tires for 4

oh yes, I forgot to add that in there, I was planning on getting axels and the carbon drive shaft upgraded, but I wasn’t planning on hitting the drag strip. Which tire you recommend?

Don't get "axels" or this Axl, either! Tends to make things a bit rowdy.

I have 555r2s and I had no problem spinning them with a 6769 at ~600hp.

Speaking of, I have a clean, low mileage 6769 for sale

Don't need the heat exchanger or radiator.

Too much emphasis on power and the suspension and wheels setup is not on par from my perspective.

With that amount of power you should be running Hipermax R. I am on Hipermax S and it’s brilliant but no way the spring rates and damping force is sufficient for the dynamics of a 700hp car.

You should also be running a set of wheels that is as wide as possible with an offset that is close to stock for a more predictable handling. That’s why I went for the Advan GT Beyond, 10.5 front, ET 32 and 11 rear, ET 35.

The thicker the tire sidewalk, the more lateral and longitudinal grip you will have. Thicker sidewalks also give you more grip range so the breakaway will be more gradual and more controllable when compared to a rubber band sidewall. Try to aim for a 35 profile. With you setup, I recommend A052 275/35 19 and 295/35 19. Together with the Hipermax R (leave the dampng and ride height settings on default until you know the car more) the wheels size and offset I have recommended, handling with be predictable and on par with your power goal.

but for this ride I was hoping to do street and occasional track, that’s why I went for the hipermax s, I thought the R will be too track focused.
For the tires I. Was thinking getting another set that’s 18 inch rims for track, I think for this one it’s more for daily street driving that I have set up

I was thinking of getting another set of tires just for track, but current setup for tires is just for street driving, but what tires would you recommend? I was thinking getting the cup2 tires for 4

I’ve got an MT making around 700–800, and honestly Cup 2s just aren’t a good street tire. The heat profile isn’t right unless you live somewhere super hot and drive like an absolute animal. My 305/30 RE71RS are awesome for lapping on pump gas, but they start to struggle on E once you’re past ~33 psi, even at just 60 mph.

For the street, run an NT555R2 in the rear.

I’m assuming when you say “track,” you mean lapping and not drag racing? The new RE71RZ are solid for lapping. A052s are great too, but they need way too much camber if you also care about straight line stuff.

If by “track” you meant drag racing, don’t do that. You’ll snap your driveshaft in the first few launches on a sticky tire. And once you upgrade that, you’ll end up needing axles… and that’s before even getting into the fact that first gear is a 4.0:1 and second gear isn’t ideal for launching an MT and there's currently no straight for swap or fix for this trans. Anyway, just my .02
