chucho, you are probably better off porting your throttle body.

how could you not gain any power. i know that with v8's going non EGR frees up some power. hell you are burning exhaust gas in your combustion chambers. 97 you might be right, it might not work for his engine, but for others it does work.

If you live in an area where you have to pass emissions DO NOT mess with your EGR. You will fail if you mess with it. As far as hp, gains would be minimal. EGR stands for exhaust gas recurculation. basically the way it works is by letting some exhuast gas back into the intake manifold. the exhaust gas is mixed in the combustion chamber and burned along with the new air. the reason they do this is for emissions and and to lower the combustion temperature. you could free up a lil power if you went non EGR, but you could be in some trouble come time for an emissions test.

I live around Chicago Heights, so Woodfield wouldn't be too bad, but if we put the meet in a more central location in illinois we might get more midwest celica owners. Maybe Lasalle-Peru Area....which is in the center of the state on i-80. Starved Rock state park is there, that would make for some cool background for pics...and the jcwhitney factory outlet is there too...just an idea, woodfield would be cool too, i have heard good things about it

Enjoying the finest Mad Dog 20/20!

This was listed for 90-94 MR-2 and Celica All-Trac. There will be slight variances depending on your application, but for the most part, these figures will be similar for most 3sgte's.

Ok,
Haven't been on the site in a while, just thought I would post some info I have on the 3sgte for anyone who is interested in rebuilding one. I don't know if anyone cares about this or if this is a repost. I got this info from the prosis database at my college today during my engine rebuilding course, I already have my engine rebuilt so I was just checkin engine specs and helping other people. Also, the engine shop has a 3sge and two 3sgte's as demo engines. I am eventually going to rebuild a 3sgte and swap it into my celi, but for now my project is a 69 buick skylark that I am swapping a 425 olds big block and th400 trans into (360 hp and 465 lb.ft. of torque....stock ) anyways, i'll shut my big mouth now and post some of the info, if you need more specs on any other engines, let me know.

Thats all for now, I know not everything is complete, but it is some info for anyone who is doing some work on the wonderful 3sgte engine.

ok, so my dad was driving my car today, and he told me the check engine light came on. when he got home, i went to check it out, and sure enough, the light was on. also, the car was idling at a little over 500 rpm. any idea what is wrong?????? thanks guys

Basically, this is how an underdrive pulley like this works: by the pulley being lightweight and having a smaller diameter the motor does not have to work as hard to power your accessories, thus increasing your horsepower. According to ASP this pulley showed an 8 hp gain on the dyno. I will take $85 for it.

Ok, I need to sell this...I will consider any offers....let me know

I am selling the ASP underdrive pulley that I bought for the 7A-FE. It was never put on. I bought it for $125 shipped. I have the receipt and I am willing to sell it for $100 shipped. I need money for my engine swap. (i'll also throw in the alternator and a/c belts no extra charge)

where did you get the trd windshield banner? i was thinking about getting one.

well said snadman. i have had good luck with the ngk iridiums. the ngk high performance wires are nice too. i noticed i slight increase in performance.

You could always put together a turbo kit using parts from another car. I recentley bought an entire turbo setup off of a 92 eclipse. With a little modification this will hook up beautifully to my 7A-FE

i went to hin in chicago. it was pretty tight. too many eclipses and hondas though. only 1 6th gen celica was there. the guy had a veilside body kit and had a 3sgte engine swap. i tried to find the owner but couldn't. the ladies there were incredible. have a great time. btw, bring a camera for all the pictures you will get take of yourself with hot girls. i ran out of film within an hour!

make sure you use a torque wrench when putting them in. they have to have the right amount of torque on them (check your manual) i believe that it is 13 ft. lb's, at least it was for my 97 st. also be sure not to cross thread the plugs, that will leave you in a big mess. i think the gap is .032", check to make sure.

the st's stock exhaust size is 2" as well. i know because i just took off my cat and i measured. i am putting on a custom straight pipe. no more cat for me

I'm all for the JSpeed strut bars and a short shifter, maybe some kind of coil overs too!

having an attorney helps a lot. they generally can get your fine reduced and shorter supervision (at least in illinois). 3 tickets, 4 accidents, and my record is totally clean. but if you know an attorney who can help you out for relatively cheap, go for that. i am lucky...i have legal connections! btw, if anyone needs to get out of a ticket in illinois i can help

i can't find any place that carries obx products for celicas, even toyotas, they claim to have them on their website but i can't find a vendor anywhere. it is pissing me off too. if anyone finds anything out let me know.

just wondering...how soon are we looking at group buy? the sooner the better

Ahhhh...it is nice having your father as a criminal defense attorney and your uncle as a judge...i got a ticket for 70 in a 35 and didn't even have to go in front of the judge, it was dismissed. my brother got stopped in wyoming one time for going 105 in a 75 and was let off with a warning. my advice, make some legal connections

count me in on this if it is not too late! i am ready now
