New '98 Supra

Mmeyer183 · 02-17-2013, 08:24 PM

So I have found a bone stock manual 1998 twin turbo supra that I am going to buy, as it has been the one car I have wanted for the longest. Now I am perfectly happy with how it is and how it drives since it will be a daily driver, but I have been considering doing some modifications to it. Im sure there is a thread on hear somewhere, I just havent had the time to sift through all of them yet. But basically what Im looking for is around 600 rwhp.

I have a neighbor who is pretty good with cars and I have been talking to him about it. Basically to reiterate what he said, "you can easily get 50-100 extra hp off a stock with simple modifications. Anything past that, you need to start upgrading internals. You will need tochange out the rear axel, different intack plenums, throttle body, new injectors, fuel rails, fuel pressure regulators, different clutch, flywheels, driveshaft, pistons and rods, spark plugs, etc..." his list went on, but he says with these mods you can easily handle 800 hp if not more.

Again Im just looking to reach 600 rwhp, but if I decide to go for more later on I would like to have the option to do so. I just need someone to point me in the right direction.

I,it sounds like your neighbor does not know a lot about the TT supra.
You don't need to upgrade internals or suspension for 600rwhp.
But with that power you will need single turbo conversion and complete fuel system upgrade and a few other upgrades.
AND you will have to run high octane fuel

Maybe in the future if I was to go bigger, but Im just going to be using this as a daily driver. I would just like to get around 600 rwhp.

I knew I was going to need at least fuel system upgrade. I was just unsure of what else would be needed. And why a single turbo conversion and how complicated is it?

Does it have to be race fuel, or can it be 93 octane from a pump?

There's supras running 1000+hp on stock internals on pump gas all day

1.The stock twins wont be able to make that power you will have to upgrade the turbo.
2. It is not that complicated but it is expensive and you will need at least a piggy back system. complete fuel system upgrade and few other stuff

To make that power you will have set the boost up much more and you will have to use much better fuel then 93

Don't believe that. you can't boost that much with pump fuel it will destroy the engine

Sonyps307 · 02-18-2013, 04:34 PM

With a fuel system upgrade and bigger turbo he can make more then 600hp on pump gas it's been done plenty of times.

He is talking about 600whp and i think they use methanol injection to do that

Mmeyer183 · 02-18-2013, 08:17 PM

From what I've gathered by looking around and reading, I will need a single turbo conversion (Possibly a 72mm turbo, havent quite decided), an upgraded fuel system and pump, aftermarket cams, midpipe and exhaust, a new computer, a boost controller and a boost gauge. Im pretty sure I can still run everything else as stock, but correct me if Im wrong. I might do a few other odds and ends such a fuel rails and things like that.

complete fuel system.
67mm turbo will work aswell
you need a piggy back system for ecu.
upgrade clutch kit.
and a decent meth injection if you run pump fuel.
