EVERY ONES SAYING OH DONT RACE A CAR WITH FORCD INDUCTION YOU WILL LOOSE.... WHAT THE heck is it? and do they make it for a lexus gs300?? if so how much?? need to know

turbo, or supercharger, anything that FORCES air into the engine, hence Forced Induction.
you can get a turbo for pre-98 GS and post-98GS300
they can range from 3000-??? most likely you owuld pay around 4500 for a good turbo kit at abotu 8PSI (how much pressure is being pushed into the intake manifold) about 350flywheel HP

no one makes a kit, but most know how to do a GS3 turbo application, but only some know how to do it up to the point of fuel return and custom fuel delivery systems. thats why a turbo under 400flywheel HP will be fine, but over requires work and money.

Yes, yes..
Forced induction "forces" the air into the engine, instead of the engine "sucking" it in. A turbocharger or a supercharger does just that. The purpose is to deliver more air into the engine, thereby increasing horsepower and torque.
TURBO = exhaust driven, gets very hot (to the point of glowing orange), needs an intercooler to cool down the air entering the engine, has "lag" - by the time the exhaust fumes spool up the turbine and it starts forcing air into the throttle body, there's a short (1-3 second) delay (depending on the size and type of the turbo).
SUPERCHARGER = belt driven, no lag, virtually no heat (although some superchargers do get hot and require intercoolers), there are several types of superchargers (screw, centrifugal, roots).
NOS = Nitrous Oxide, it's not really "forced induction" - more so a "boat-load of oxygen" which is needed for combustion. More NOS = more power. Also, the Nitrogen in the NOS mixture acts as a buffer during combustion and is an AWESOME intercooler for the air that's fed into the engine. There are generally two types of Nitrous systems (plate injection and direct port injection).
There's also a Miller-cycle-type engine.. It is a basic engine that uses delayed intake-valve timing and a Lysholm compressor to extract more power than would otherwise be available from the engine. The belt-driven, forced-induction Lysholm compressor is similar to a supercharger, but it is more efficient. Not really available as an add-on, it was only seen in the Mazda Millenia-S car.

98+ GS300, 2JZ-GE+VVT-i, there are no turbo kits but custom jobs can be done. XS Engineering made a custom turbo setup for the IS300 so it should be relatively easy for them to do it on a GS300. So there are no BOLT-ON KITS yet, but yes CUSTOM JOBS can be done.

so around how much a custom twinturbo setup would cost?? any 1 have any clue? would a TT setup produce more power or a single big turbo? how much HP??
and how does "twin" turbo work??
and how does "twin" turbo work??

Twin Turbo engine are good because of low Lag and you can make them Sequential,,,, a Singel Turbo upgrade for the Supra produces more horse power because it uses a bigger turbo but you have more turbo lag ,,, if you use 2 BIG turbos you loose the engine
I like the Idea of Twin turbos, but that is not the time for me yet work on One turbo make it work then do Twin Turbos ,,, and my project on a V8 is use Quad MINI turbos if possible lol JUST AN IDEA GUYS.
(yaa I have many dreams of my GS4 having Quad Turbo) Sniff

quicker spool up or better top end

When you say which turbo setup (single vs twin) will produce more power, it is relative to the actual turbo itself. However, we have to call the variable "boost." It is dependent on the turbo sizing and sometimes the construction of turbo. The stock twin turbos from the MKIV Supra is extremely responsive because of its initial spool up and help with a sequential system. They spool well because those CT20s are very dinky and the turbine wheel have little roational intertia to overcome compared to its sister turbo the CT26. Reliably the stock TT setup is good for about 450rwhp w/ a front mount intercooler for safety. *HKSGS4POWER can help w/ these numbers* Whereas on most Supra TT, the next step is a streetable single turbo such as T04S or a T61. They will take longer to spool up but can blow out way more air than the CT20s. If you want all out Gonzo get something close to a T88. If you want ultimate spool up, I recommend you get a stand alone system like a Motec or F-Con V Pro, two T-66 (.6+ A/R), and NOS to help spool up the turbo. As for power, it is relative to the engine, drivetrain, fuel system, turbo. However, the ultimate power does not come without a price. It may not be streetable and reckless to drive on public roads.
Seriously, you will need to ask yourself questions like how much power do I want? Is it a track car, street car, or drag car? Notice that I have not mentioned the factor of money.
I hope my input helps.

blow dryers!!!

Yeah, there are two respective hair/blow dryer kits for the GS400 (Swift-Racing) and GS300/Is300 (Area51). I don't know too much about the Swift Racing blower but Mkilty should. The GS300 hair dryer is good for 250+ hp to the ground on 5.5 lbs of boost. Interestingly enough it's not running an aftercooler. Kit retails for slightly above $5000.
