I'm not a Supra MKIV owner... yet... LOL I'm saving up to getting one atm, I wanna get rid of my temporary car asap. I've done a lot of research into Supras, so I might be able to help out a bit.

1998 Supra RZ are actually quite rare (well here in Australia anyway). After the mid-late 1997 models the engine isn't a standard 2JZ-GTE, it's still called a 2JZ-GTE but it's got VVTi which means this engine has more power over the previous 2JZ-GTE. Since I'm a Supra lover I'm going to be a lil bias and say that there isn't much to look out for but just try and look for one that is clean and don't buy the first RZ you see, that's a big no no, unless you consider yourself a lucky person.

As for the modifications, you can get a lot out of a 2JZ-GTE with a stock bottom end. One of the most famous Supras in America is owned by a guy called Peter Blach. His Supra pulls 1132hp at the rear wheels with a stock bottom end which is about 1331hp at the flywheel. Suprisingly that isn't the most powerful Supra in the US. He is running a Garrett GT42 dual bearing turbo with a GReddy 4row intercooler. But a turbo and cooler isn't everything when it comes to performance, you also have to remember to maintain your engine.

BoostLogic is very famous for their turbo kits for Supras. It is a good start to give them a call and ask what is best for your power requirement. SP Performance or something is also very famous for Supra tuning, give them a call too. It's better to seek the professionals and Supra specialists for help rather than a forum.

Hope that helped :D

I'd like to warn you first that having too much power (requiring a VERY tight on/off style clutch) is a real bear to drive. It really starts to suck after about 600hp. Also keep in mind that with a stage 3 turbo, you will have extreme turbo lag and have pretty crummy acceleration. A stage 2 is a better compromise

the stock 320 hp 315 ft/lb isn't anythign to laugh at either. I've driven one of these puppies (my old boss owned one) and it was pretty intense (and I've driven porsche's and lamborghinis before). He actually sold it because it was too much for him.

I was thinking about going with stage 2 instead of 3. Or even a BPU kit, considering its my first car and all :p

Thanks for the help so far.

i plan on getting one after i get out of college. keep the focus as a daily driver (original plan was to boost this to at least 250whp, but then i saw this 800HP supra)

gonna up the turbo and build the engine to 800+hp and use it as a track car.

i love supras, their engines can handle so much and have so much potential

IMO, a Mark IV isn't worth what people are asking for them. The fact you can get insane HP out of them is cool, but I can think of a lot of other $35-40k used cars I'd rather have that would be a better track car than a Supra (if not as insane).

Or you could save the money and wait for the new V10 project Toyota has ... I have high hopes for that, and you wouldn't be paying a collector's premium.

Each to their own opinion. Why do rich and famous people like Hulk Hogan drive a modded Supra when he has the money to do up a Ferrari? It's just a matter of what people like and they're willing to spend the money to get what they want out of life. You've got the Supra lovers, the GT-R lovers and even the Civic lovers. I don't say to someone with the riced up Civic "Hey man, you wasted your money on that piece of shizzle, you could've got a better car with all the money you spent" because I can understand that the car to them is a part of them.

I agree, I'm just saying last generation Supras have gone up way too much in price lately. Same with last gen RX-7s. You'd be better off buying an older generation and spending more money on modifying it, IMO. Or, getting somethign that's actually a rare car, like a Skyline ;)

I?ve seen so many people buy cars like that for their first car and just end up crashing them within a month or 2. It?s probably not the best car to buy for your first car especially if you?re just starting out. Just because you have a supra doesn?t mean you?re invincible?

Theres difference though. I'm probably not crazy like them. I don't speed, even when theres no one around.

Also, the latest gen Skylines are illegal here.

Oh ok, well over here in Australia, it's like Skyline central, everwhere you go there are Skylines. I suppose you can make your MKIV look different from the others too if you really cared about looks. I personally don't like a car that attracts too much attention.

lol,..

Go to a pet store. Get a brass air valve. Connect inline with the wastegate refrence line, bleed refrence boost to the atmosphere. Fools the turbo into thinking its not making what it really is, and makes more boost.

The USA spent millions to develop a pen that could write in outer space.

The russians did it for free, they used a pencil.

keep it simple

^^ And what do you drive?

With the MKIV, try and find a 6 speed aerotop. Most aerotops came in auto so it will be pretty hard to find.

585845317[/snapback]

Apparently aerotops only come in the SZ models which are non turbo and 5 speed. If there were any 6 speed aerotops then that means it's not a factory aerotop. Eitherway you don't get much wind into the car with the aerotop unless you open up the windows too... but I guess it looks good.

No actually, there are RZ and GZ (luxury model) that are aerotops. Also they tend to have a lot of body flex and the frame kinda bends.

585846978[/snapback]

You could be right, that's why I said "apparently". I've been hearing a lot of different things, but if I look for a Supra I wouldn't care if it had an aerotop or not, I take the aerotop as a bonus to the looks that's it.

    • The quantum search for Time's origin had an equally mind-boggling conclusion by Sayan Sen Image by Steve Johnson via Pexels A theoretical study from researchers at the University of Surrey suggested that the direction of time may not be fundamentally fixed in certain quantum systems. The work, published in Scientific Reports, examined how the “arrow of time” could emerge from microscopic physics and found that time-reversal symmetry can remain intact even in models used to describe processes such as energy loss and thermalisation. The arrow of time refers to the observed one-way direction from past to future in everyday life. In macroscopic processes, this is easy to see. Spilled milk spreads across a table and does not gather back into a glass, and heat flows from hotter objects to colder ones. These processes shape the common sense idea that time moves in a single direction. However, at the level of fundamental physics, many equations do not prefer a direction of time. Time-reversal symmetry means that the same physical laws can describe a system whether time moves forward or backward. This has made it difficult to explain why irreversible behaviour appears in the large-scale world even when the underlying rules do not require it. Dr Andrea Rocco, Associate Professor in Physics and Mathematical Biology at the University of Surrey, described this contrast: "One way to explain this is when you look at a process like spilt milk spreading across a table, it's clear that time is moving forward. But if you were to play that in reverse, like a movie, you'd immediately know something was wrong – it would be hard to believe milk could just gather back into a glass. However, there are processes, such as the motion of a pendulum, that look just as believable in reverse. The puzzle is that, at the most fundamental level, the laws of physics resemble the pendulum; they do not account for irreversible processes. Our findings suggest that while our common experience tells us that time only moves one way, we are just unaware that the opposite direction would have been equally possible." The study focused on open quantum systems, which are quantum systems that interact with a surrounding environment. This environment, often described as a heat bath, can exchange energy and information with the system. The researchers used this framework to study how a direction of time might appear even when the underlying physics does not enforce one. A key part of the analysis involved the Markov approximation. This is a simplification used in many models where the system is assumed not to retain memory of its past states. The idea is that changes depend only on the current state, not on earlier history. This is commonly used when studying thermalisation, which is the process where a system settles into equilibrium with its environment. The study also used concepts such as master equations, including the Lindblad and Pauli equations, which describe how probabilities of different quantum states change over time. Another related model discussed was quantum Brownian motion, which describes the random-like movement of a quantum particle interacting continuously with its environment. In these descriptions, a “memory kernel” can appear, which is a mathematical term that accounts for how past states influence current behaviour. The researchers found that applying the Markov approximation did not break time-reversal symmetry. Even when the system interacted with an effectively infinite heat bath, the resulting equations of motion remained symmetric in time. This meant that the same mathematical description could, in principle, run forward or backward in time without contradiction. The study further showed that standard frameworks used in open quantum systems, including quantum Brownian motion and master equations like the Lindblad and Pauli forms, could be written in a time-symmetric way. These equations are typically used to describe processes that look irreversible, such as dissipation and thermalisation, but the results suggested they can also be interpreted as allowing evolution in both time directions. Thomas Guff, Research Fellow in Quantum Thermodynamics, said: "The surprising part of this project was that even after making the standard simplifying assumption to our equations describing open quantum systems, the equations still behaved the same way whether the system was moving forwards or backwards in time. When we carefully worked through the maths, we found that this behaviour had to be the case because a key part of the equation, the "memory kernel," is symmetrical in time. We also found a small but important detail which is usually overlooked – a time discontinuous factor emerged that kept the time-symmetry property intact. It’s unusual to see such a mathematical mechanism in a physics equation because it's not continuous, and it was very surprising to see it appear so naturally." The researchers also noted that deriving a one-way arrow of time from time-reversal symmetric microscopic dynamics remains an open problem across fields such as thermodynamics, statistical mechanics, particle physics, and cosmology. Their results suggested that some standard descriptions of irreversible behaviour in open quantum systems may be better understood using a time-symmetric formulation of Markovianity. According to the study, processes such as thermalisation, which are usually treated as irreversible, could in theory be described in a way that allows evolution in either time direction under the same rules. This does not imply that time reversal occurs in everyday life, but rather that the underlying equations do not strictly enforce a single direction. Overall, the findings suggested that the perceived direction of time may emerge from how physical systems are modelled and approximated, rather than from a fundamental asymmetry in the laws themselves. The researchers noted that this perspective could have implications for ongoing work in quantum mechanics, thermodynamics, and cosmology on the origin of time’s arrow.
