I'm not any new to cars, just to the forum. Just wanted to say whats up and tell a bit about myself.

My name is Nate and I'm a 3rd year ME student at Tech. I have a 1991 Toyota Celica GT. I love working on cars/engines I just wish I had the money I need to really fuel my hobby.

The car, its still N/A and this one will stay that way. I'm working on a few things right now for it since there are limited aftermarket products for it. I'm working on a custom intake manifold, larger TB, AF gauge... I need to gut the cat I have on my car. its a flowmaster high flow cat that i have had on for about 3.5 years now and its time to just let the gasses flow freely. I run a perfectly clean intake charge, if you know what I mean, and I have the stuff to put on my next CAI (part of the old one fell off while driving in the rain).

Is there a plase around here that I can go to work on my car? I have most of the tools I need, I just need space preferably with a lift.

Are there any other 5th gen Celica guys here at Tech?

anyway, just wanted to say hi and I lood forward to good times with you guys.

welcome, but just to let you know, gutting a cat will yield you no gains and a raspy sounding exhuast. And whats a "clean intake charge"?

 

im gonna pretend i didnt hear that.....you may want to edit that post.....

a good high flow cat works wonderful.....only reason mine is off is when i am at the track, i hav ea launch control device that will destroy my cat due to it killing the ignintion, loading the cylinder up with raw fuel. thats why mine is off....it sounds RASSPPPY without it, too.

 

I'm not taking it off for sound purposes. When I orginally got the cat I was burning a little bit of oil and that got progesively worse, hence the rebuild. I have a feeling that the cat is cloged a bit because of the two years of burning some oil, thus producing more back pressure than I want.

Clean intake charge = no crank case gasses or exhaust gonig through the intake.

Gutting a stock cat on a car is rather stupid IMO, it 99% of the time hurts performance because it affects exhaust flow negatively. Just make yourself a 30-40 dollar test pipe and save the expensive cat.

 

i just bought a 1991 gt-s...don't much about it...just liked the car and wanted to learn something new...so anybody got advice...

 

good god this is a old thread, did you have to dig into the archives to find it...

 

How the hell do you even find threads this old?
