6G Celicas Forums

Hello Everyone,

First off I would just like to say thankyou for everyone who posts on this web site, I have found out so many different things just by reading other posts. Again this is a great site, thankyou all.

Anyway,
I own a '96 Celica GT with a 5s-fe. I currently have:
NGK Plugs
Catback exhaust 2.25" pipeing
CAI
Header

My car has 148,000 miles on it and I was just wondering how I can get some more horse power out of it without swapping and without throwing in a turbo (seems like alot of miles to turbo, prolly a waste...). At this point I am kind of out of ideas. I was thinking of putting an MSD ignition box in, however I was reading on here that I will see little to nothing by doing so. I also thought about adding one of those "racing chips". Again, I read on this site that these are crap.

I am pretty much learning as I go. Every performance upgrade to my car I have performed (except exhaust) so I am not afraid to get my hands dirty. Any thoughts or ideas will be highly appreciated...

an apexi safcII will get the most out of that intake and exhaust, then advance your timing 15 degrees and use 91 octane. thats all i can think of

I dont know how to advance timing, i wish someone would do a write up lol

I am new to Celicas, and maybe I am out of line here because of a lack of knowledge on the Celica's engine, but I would be very careful on changing timing that much without knowing your AFR's. Even a knock counter would be nice to have in order to see when your detonating. I come from the Subaru WRX/STI world and its scary how many people modify without doing it properly. A CAI and an exhaust, in my opinion, requires some tuning to the EMS because of the change in airflow. It would be nice if Cobb Tuning or TurboXS would release a couple "on the shelf" maps to upload.

thats why i said get the safc2 it has a knock sensor, and people change the timing 15 degrees on celicas all the time at meets, you just need a timing light and a 91 or higher (i think) octane fuel in your tank.

subaru wrx= boxy rice

Ok - thats good. See, i told you I knew nothing about them

but seriously, is that 15 degree increase overall? At any load, and any RPM, and any TPS? Or can you advance in increments? Does that piece also allow to add or dump fuel?

thanks




Subaru = AWD Turbo boxer engine

subaru=awd pwnage
wrx=boxy rice lol


but yea the apexi safc2 allows you to lean out your fuel or add fuel at watever points on your fuel curve you want, so basicall you can lean out your fuel mixture where ever you want on your rpm curve. You need to dyno tune it though.

as far as the 15 degree advanced timing, i dont really know what it does but im positive it gains hp lol.

Thanks for the input guys, I will look into the SafcII. As far as timing goes, i'm not sure I would want to mess around with that...

yea timing is hard, ive heard people talk about it being fairly easy but it doesnt seem easy to me lol

i think someone needs to do a write up about it

Nitrous. It'll yeild more power then any other said mod.

expensive and to easy to waste, wont pass inspection, bad for your engine, and youll still need an apexi safc2 and advanced timing or you wont be able to provide ample combustion

Also if you use nitrous that 148,000 mile engine will die at 170,000 lol

if you do decide to get nitrous then get a purge kit too, they look hella cool

Expensive? Considering what you pay for a turbo, it's far cheaper. Sorry, I totally disagree with your 'expensive' comment. Nitrous is the cheapest hp avaiable.

Inspection? What inspection? And all the hardware is easy to hide and if you have any type of inspection, you can just yank the bottle.

Bad for Engine? No worse then boost.

Providing ample combustion? Do you have any idea what you're talking about? Back that one up, cause you're totally wrong.

And your engine will last with nitrous as long as you have half a brain and know how to maintance your engine.

And purge kits are only good for clearing out the lines before injection. Don't just purge to 'look cool', it's a waste of nitrous.

^amen

forced induction is forced induction..
a supercharger, turbo and nitrous are all going to shorten the life of your motor by a decent amount since a 5sfe was NEVER designed for boost/nitrous.

gains will come best by
a) becoming a better driver (autocross events(stock), track days (you get an instructor)
b) 2.25" exhaust with headers
c) oem intake w/k&n drop in (or do the accord CAI mod)
d) there are no "racing chips" for our car....anything you see is crap and a rip off
e) nitrous will be the cheapest per HP for your car (in the short run)
f) turboing is going to be much harder than nitrous, STILL will not pass inspections, and in the long run it will be cheaper.

g) i'd highly suggest neither until you've fully exploited the abilities of the car in its current form and really learned how to drive

Everyone calls nitrous expensive due to all the bottle refills. If you really only use the stuff when you race and don't squeeze on every drive, you'll be mazed how long a bottle will last.

Turbo was always out of the question so why did u bring it up, and an experienced mechanic INSPECTING A CAR LIKE EVERY SINGLE CAR IN AMERICA GOES THROUGH wont notice his CAI, headers, catback and not take a closer look for the many illegal performance mods there are out there? A yanked out tank isnt going to hide jackkk.



Are you serious?!?! dude your adding way more oxygen to the engine. The stock engine doesnt know your going to be pumping pure oxygen into it and wont add extra fuel to compensate. THATS HOW PEOPLE BLOW ENGINES UP WITH NITROUS. Read about it before you open your mouth, nitrous is cheap power and anyone who knows anything about cars is going to stay away from cheap power!

and if nitrous is so cheap then why are you worried about him wasting it through a purge?

anyone who knows anything about cars....is going to look at nitrous...
look how PROVEN it is with muscle cars....my friend just dropped a 100shot on his M3....MANY MANY cars are PROVEN very successful and reliable with nitrous...

cheap power > you

maybe on a muscle car but a 4 cyl puttputt with less than 100hp?

toyota didnt build the 5sfe with any intentions of power, if nitrous was the god of all power like you are making it out to be then why do so few celicas have it? how come people spend more than three grand and endless hours of work on 3s swaps when they could be bolting on the o so amazing nitrous.

It gets a bad rep for a reason, its pussy juice; and how is cheap power ever a good idea? you get wat you pay for, thats the rule and it will never change

Inspection? I've never had a single one of my car's inspected. But its very easy to hide, you just mount the silniods is a cleaver spot, hide the lines and have the nozzle plumbed into the bottom of the intake.

And as far as the combustion....the wet kits come with a fuel injector thro the nozzle. Even the dry kit comes a way to bump up the fuel when ur spraying.

It's not pussy juice, you just don't know dick about cars. Juniors, I've been playing with nitrous for years, you're outta league on this one.


So few celis have it cause of idiots like you spread all this misinformation.

I had my timing advanced to 18 degrees BTDC with 91 octane gas. no problems at all. it makes the car accellerate a little faster in the low rpms. here, I'll even do a write-up for you right now:

1: on the left side of the engine, near your belts and stuff, you should see this plate with numbers on it. it should say like 15, 10, 5, 0, 5. if you point a timing light set to 0 (if you have an adjustable one) at it, you should see a mark on one of the belts right next to the 10 (assuming your timing is in spec) (also, the car should be running)
2: now, go over to your distributor cap and you should see that there is this one 12 or 14mm bolt kinda above it slightly. loosen up that bolt, and you'll see that you can now rotate the whole distributor cap.
3: turn the distributor cap clockwise a little, then go back and check your timing, turn it a little more, check the timing, etc. until you are at your desired spec (I think the max it goes is 20 or 25, which might ok for 93 octane, but I'm not sure, I did 18 with 91 octane with no problems. I also ran it at 15 BTDC on 89 octane; again, with no problems).
4: put the bolt back in and enjoy!



now, other ways for power. cams. webcams makes some for the 5sfe; but I'm pretty sure you'll definately need to tune after you get those. I'd say get a greddy emanage ultimate. it's better than a SAFC in that instead of just altering your map signal which screws up your timing, you can adjust the injectors as well as the timing, and a bunch of other stuff. but it's about twice as expensive.

other than that, maybe you could find a bigger throttle body somewhere. I've head of people using a 5.0 mustang throttle body and a supra 7mge (or 7mgte, can't remember) throttle body. but I don't know what modifications they had to do to get them to work.

lmao, ok dude i am the only reason nitrous isnt used by thousands of celi owners...

Nitrous isnt used because its not practical. To run nitrous successfully and safely, you have to introduce precise amounts of additional fuel with precise amounts of nitrous oxide which requires something like an safc2 or a piggyback fuel management system. All of the extra oxygen provided by the nitrous oxide must have fuel with which to burn or you will damage your engine severely. On top of that in order to reach a power gain through all the rpms, not just the lower ones, you have to advance your ignition just right and it is too easy to run too much ignition advance with nitrous, and too much will not only hurt power, it will quickly bring a nitrous engine into detonation and destroy it.

So in the end in order to not kill yourself and your car you will spend a ton of money getting the piggyback and your ignition right, on top of dyno tuning and refills. Not at all practical...

O and by the way sherlock he lives in cali which has the most picky and strict inspections in america, in addition cali is home to thousands of ricers who think nitrous makes your car a rocket and im sure mechanics know to check the intake tube or the intake manifold, it takes 2 seconds and they get to charge for removal so its 2 seconds well spent.

Jebus, you are so misinformed. The fuel is easy to get right. If you run a wet kit, the supplied pills that care of it. Thus, you do NOT need any dyno time or tuning or even an AFC.

And if you're smart, you can easily hide it. I've installed a bunch of kits for street racers who wanna sandbag. None of their victums ever know about the nitrous. None of my clients have had any complaints

If nitrous was so dangerous, you wouldn't see it on every f-body.

And so you know, even if tech's are checking the intake pipe, there's other places on the intake mani to put it.

You're very misinformed and I would think you'd notice.
