Hey i had to reply just because your name is so Badass. Anyway i havent yet but im pretty damn sure it will require expensive shtuff to do it like a VPC and stand alone fuel system but im not sure. Possibly Just a VPC i thought about doing this a while back because the egr stuff makes the engine bay look so cluttered and i dont think it would be street legal once you do it either.

Well it looks like im the first for a mkiv supra n/a setup to remove the egr pipe out of the throttle body and block the egr system and still have the car running right . it was a pain but once i saw the schematic for the egr hose's i was fine. i definetely picked up a improvemnt in throttle respone and as for emissions i will find out if i was if the car is running mint and it already warm thers no reason it shouldnt pass. the same is for the turbo supra's ,the pipe i removed out of the intake manifold easily gave me more airflow/ plus disturbing the flow path and it is now how it should be. atleast for my car :0 anyways with the car in neutral tap the throttle i it revs so freely and pulls alot harder on the top end. i even had the car sideways pulling out of a gas station. keep in mind i have a automatic I took my friend for aride in it he couldnt believe it was all motor. he kept asking its not turbo ? with a big smile on his face from the ride you sure its to quick. by the way the car has a stock exhuast. i also removed the coolant pipe that goes threw the throttle body this lowers intake temperature and so does blocking the egr and removing the pipe.
you will see a big gain when turboing this setup and a decent improvemnt on a n/a car remember thats your collant loine is keeping your throttlebody and aroung 160 degree . high intake temp=lost power/effecientcy.in my old 95 chevy impala with a lt1 worked i saw i easy 8-10 horsepower improvemnt on a dyno no joke its proven. If you decide to do this setup on your non turbo 93-98 supra ill give you all the details. but remeber who told you about the n/a egr mod and coolant bypass mod first .(XDreamer) p.s im going to dyno the car in the next couple weeks. all i have done is about 50 dollars in parts from pep boys and alot of time and fabrication . but its a hell of alot faster then when i bought it. the car right now weighs about 3100 lbs .

Are there any n/a mkiv supra owners on long island ? I just got my car and i am one of the only n/a supra around where i live.

Not to burst your bubble but I think Dave Henry may have beaten ya to the egr removal.

As for the coolant/throttle body bypass, I was wondering about this same mod, too. I've read of DSMs doing this mod.

Let us know how things go and good luck

lol ok then im the second supposedly to do the egr black / pipe removal on my n/a and the first i know of to do the coolant bypass. the cars pulls alot harder. and i noticed the intake amnfiold and throttlebody are alot cooler after runnning it for awhile. i am going to get a temp gun and tell you the exact difference in power/ and heat. i have great sucess doing this in my impala and the same wit hthe supra. i dont konw why everyone hasnt being trying this.

Cool beans. :) I'll probably try this when I get home too. Wasn't that coolant hose(toward the drivers side) under the throttle body fun to get at. :)

I need help with this mod. Thanks and LMK

I'm not even sure where the EGR system is at on the NA, but I'm pretty sure that I know where it is.

Go to www.MKIV.com and look in their tech tips. Great instructions, pics, and alternatives ranging from blocking off to complete removal.

I believe that is for the TT. If I'm not mistaken, the EGR on the TT and the NA are different. Please correct me if I'm wrong.

hey guys sorry i have just seen the rpelys. the tech article for the egr removal is not the same as the n/a egr removal block. I will write up a parts list and how to. the way i did it i have to but a used intake manifold to reverse the mod but i can show you how to do it without having that problem . it cost me at most 20-dollars in parts and some time to do it.iwilll write up a tech artcile on nautral aspirirated specific collant hose re-route and egr- pipe removal and block. . All i know is if i pull out of a gas station like making a left or right out of it on to a main street i can make the tires smoke for a good amount of feet no jokei did it tonight i had then smoking till 7k rpms then i let off all i could smell was burnt rubber when i stopped at the red light and if i am making a u-turn i have no problem gettin the car sideways. take in mind i took 100lbs off the rear of the car and mines a automatic yes automatic n/a but the auto shifter comes in handy i did a custom ram air inatke setup but i still have a stock exhuast and nothing big. i noticed the throttle body and intake manifold to be running alot cooler since the egr and coolant removal mods i thought of and did. :D
