6 Port Supra B58 Big Turbo Options

[McBobby Jr]

Looked at the big boost kit for the efr, their description says mani has an external WG port. But the turbo very clearly shows a factory EWG attached and arm to the internal gate.
Yet I find another pic of that turbo on some other sites and I see a normal turbine exit, not internal gate. Guessing big boost’s pics or description is for a different kit / turbo.

All their manifolds for the B58 come with a wastegate port, including the EFR lineup with IWG. There is a wastegate port block off included for IWG.

4N Motorsport kit will do, just ask for a Gen 2 flange.

Appreciate it. I’ve also come across this kit as well and like the BigBoost, Docrace and Walton, assumed it was designed for the f30 engine bay. Maybe there isn't much of a difference in engine bay clearance between the supra and f30s, but I’d prefer to avoid ordering a kit and finding out it has fitment issues.

Like Twisted said there probably isn't much of a difference in top or bottom manifold design and to prioritize gate placement, but I have a bit of OCD for heat management.

There's also a polish fabricator that makes one but its for kit cars.

CES is currently in the process of launching their bottom mount full frame setup utilizing a Xona Rotor turbo (upgraded Garret turbo?). They seem to have done extensive R&D on their shop turbo with very promising results. More recently they have fitted this kit out on one of their customers cars as well. Currently waiting for more details on release date and pricing.

For fitment on the A90, there should be more room on the hot side and front side over a F chassis with the delta even greater when comparing to an xDrive chassis with axles right below the turbo on a bottom mount setup limiting turbine/compressor size.

Damian @JAS is great to deal with, excellent customer service. I would highly recommend looking into one of his manifolds. Just ask him what you need and he’ll make it happen.

Yeah I’ve been trying to get any info on the CES kit in dev but coming up with nothing concrete.
Do you know if it has an external WG or not? Tubular or log?

I guess i can buy with confidence, but I've got time and still in the middle of planning out the build.

Yea he was a really nice guy when i messaged him. His work on the b58 is very impressive.

This is basically the CES kit,

New kits might have a updated manifold design from EOS but who knows. Its nice If youre looking for a single scroll setup and i hear Xona's are solid turbos, Robert Young has a great reputation. Also the kit could pair well with the straight-gate bracket like the big boost kit.

thanks for sharing that, that and spool both look like good candidates for custom straight gate setup since the log style leaves so much space.
Log style less than ideal but it’s maybe a good compromise being fairly cheap and compact.
I really wanna hear a log style big turbo and a tube back to back in person lol wish there were more built Supras where I live.

edit: I’m fine with single scroll as I don’t need or want lightning fast spool right now anyway. Prolly sounds counter intuitive lol

I can’t find any mention of a B58 kit on EOS site, I’m assuming it was an offering a while ago or maybe they just sold a manifold

Do you have any pics of ETS installed or in the process of installing it on your car, I’m trying to get an idea of if and where a high flow cat can be placed along the DP.

DO NOT buy that spool manifold. Who ever designed it went full retar*. They went topmount log style. Topmount should give you the room to fab tubular equal length runners and just look at that shit design.

cant do a CFD analysis in my head but the backpressure and lag must be awful.

I just got my kit and waiting on LPFP and couple more supporting mods to arrive before install.

Since I have been researching this topic lately, I have seen some manifolds that are and are not equal length. Obviously Spool is on the extreme end of a log manifold, but is there a "massive" difference between equal vs non-equal length? From what I have seen, people say tuning can correct a lot of the uneven output from different length runners but how is that on our platform?

For example - https://jncmanifold.com/supra-b58-6-port-gen-2-t4-divided-single-turbo-kit/
Not equal length, but not Spool bad, but also not P2 or ETS.

Been going down this rabbit hole as well. Since that kit uses larger diameter runner, it probably flows better compared to the spool.

Is there a massive difference? ?‍ Probably not. Assuming they go unequal length because its more complex to fab equal runners which drives up cost along with spacing issues and ease of installation. I'm trying keep the engine healthy at a close to "1:1" pressure ratio and avoid any reversion back into the cylinder when turning up the boost

Agreed. I can't find any evidence whether equal length matters enough to be double the cost. I am thinking the turbo itself matters more in the end but am open to learning more if anyone knows.
