Maybe I misread or everything is getting confusing to me. I'm new to this GR Supra platform. Am I able to make 500-550HP without ethanol and just doing a bigger turbo? I kind of want to avoid ethanol.
The car is fuel limited. So any approach requires more fuel, E, or meth. Can't even max out the OEM turbo much less a larger turbo. As always, fix the most constrained thing first. Exhaust, tune, then one of the fueling options.

Regarding the OP.. there is NO WAY anyone is installing a JB4+ in a minute. That stupid clip on the sensor in the charge pipe is at least 10 minutes of cussing, 3 trips to the computer to see what your doing wrong, and answering at least one question from your wife if you're "having fun" or why you do this hobby.

Jb4 or jb+? JB+ is close to a minute tbh. Alot of people don't use the angled tooth pick behind the connector to sliding it off with ease. No need to force.

First, I apologize that I don't know the name of all the sensors. But in my experience, the white tooth pick thing does nothing for the sensor on the charge pipe . The toothpicks work well on the O2 sensors to the downpipe, really well on the sensor under the airbox, pretty well on MAF on the airbox, and pretty good on the one by the fuel rail. But the stupid f**** charge pipe one is total useless piece of s*** that fights like a bear.

But yeah, if your toothpick works for you then the install is a no brainer 1 minute job. But if you have my luck it's a 30 minute profanity laced experience with a possible trip to the marriage counselor or perhaps an overnight psychiatric observation at the hospital.

If you are talking about a JB+, I assure you I can do it in 1 minute. However, I also spent 30 minutes swearing and tearing my fingers up the first time I tried without the angled pick tool.

Something like this:

Trust me, it changes from a rage-inducing experience to a piece of cake. If this is what you were already using and still having issues, I'm not sure how to help.

Actually I installed the JB4 and was just projecting what the JB4+ would be like because of that one connector. I didn't see that thread on JB4+ with notes about that specific connector :( I just sliding the white thing out, pressing down on it like a little lever, and that's what normally allow the connector to slide off. But from those pictures you put a pick in the other side. Interesting.

It's a badly designed connector IMO. Pushing the white piece down is supposed to act like a lever and lift the clip off a bump that holds it in place. You can't actually push the white piece down enough to fully clear that bump, so that's why the pick tool helps you get that extra bit of clearance to release it.

This. Exact same angled one. Heck, even the straight ones or a flat head would be abit difficult due to alot of other shit coming in the way.

Colonel saved me the headache for recommending it.

By the by. I broke one of those white toothpick things. Hulk smash is always effective right? :) Anyone ever find a replacement. You'd figure those buggers are easier to break or lose so they might have a bowl full of them at the stealership.

It is possible to reach 550whp on a bigger turbo. However, at some point or another you will need either meth or ethanol to push out more power, and at some point you will need both.

Same then I figured out that you can bend the sensor ever so slightly, and it comes right out.

What amount of torque is the manual transmission good to? Presumably, the amount in the post is for the automatic?

It's rated at a little less than 450lb-ft of torque. If you want big power... a manual transmission is definitely not the way to go. It would be okay if there were people that actually built up these transmissions. But there is nothing outside of an upgraded clutch.

I second the request for data. I’d also wonder if the clutch is included in the 450 ft lbs rating. Stands to reason the clutch is a frangible link in the system to protect the transmission.
