6G Celicas Forums

so after talking with a bunch of people on here and doing tons of research i decided that it was time for a change with the celica.....i have nice paint....and if i want to add on some nice lips around the edges i can do so accordingly without much trouble.. i still would like to swap out my cloth interior for a nice black leather interior and a bunch of other interior BS....i talked to art(lagos) many many times about getting rid of this 7a and asked him his perspective on the 3s swap....his feedback was do your research and learn everything you can while you can, doing your own swap will only help you in the learning process rather then having it sent out...which was what i was planning on doing anyway because i cant afford to have it sent to a shop...plus i have all the tools and resources that i would need to do it....so at first i looked into just head swaps...went as far as almost buying a 4a head from someone on here and a bunch of other stuff...then realized that might be too much work for the $$ and HP goal i would be expecting...so then i looked into turboing the 7a...but still the 7a is almost limited in what you can do to it and just squeezing 200hp out of it was not very satisfying.....i was kind of sketchy on buying a front clip from the other side of the world(hong kong) because theres a million and one things that could go wrong....so i looked into getting a clip that was already shipped into the U.S....after looking and debating i had finaly found the clip i wanted...decided i would buy it the next morning and start gathering parts together for the swap...next morning came around, i go on ebay, and its sold....$HIT!!...so i was stuck with buying the clip from hong kong...paid for it and that was that....i have the st model so i knew i would need a new trans, motor mounts, axles, and a bunch of other stuff....tracked down a GT trans and picked it up...ordered my spec stage 2 clutch from JCBASS7 i believe is his name one here? got that in no time and it looks great...he only put about 2500 miles on it and money is somewhat tight so i just got it from him.....it took the clip over a month to get here but FINALLY i picked it up last wednesday and was pumped i got it in one piece!!...now the fun begins....i will update this thread as often as i can untill my project is done the way i want it...im glad i choose to go with the 3s and im def. looking forward to the completion of this car....my man art has inspired me....the second i saw his car in person i knew i needed to get me one of those..hahha....soooo.....sorry for the novel but im def. excited and i will post up all/any info i can with lots of pics....let me know what you think and any advice is welcomed

picked it up from the warehouse it was sent to...from hong kong it went to LA...cleard customs there then was sent to philly by rail and was basically dilivered to my house...no more then 5 minutes from my house sat my new motor






i caught my man john on the phone instead of working


i pulled the line of the brake booster and @sshole thought it would be funny to push the brake...so thats whats all over my hood...brake fluid.....sweet






johnny hard at work like usual


now these next few are how you improvise when you dont have a cherry picker...this is how we do










almost completey out




and up and out of there!








looking forward to this weekend...hopefully i can pull that trans off of it and put her on a stand in the garage and start the tear down process to replace all gaskets, t-belt, new waterpump and thermostat and whatever else needs to be replaced...like i said i'll update it when i can...time and $$ are the only things workin against me on this one but im siked and def. want it done before spring time rolls around...we'll have to wait and see

So true!
The safc gets such a bad rep from a few mr2 guys that use it to run bigger injectors. But on the stock 440s, its a great tool that can be used to give you benefits similar to a rom tune. I've been running negative corrections for a while now, and it makes a huge difference in terms of drivability when taking out fuel in the low throttle map, and in the high throttle map with alcohol injection.
Ive been meaning to post something up about my experiences, but since its such a controversial topic, I didnt want to start a huge debate. lol

But in my opinion, the safc is a must have on a 2nd gen engine.

do you have exhaust on yet? coming to the meet on sunday?

Agreed, it is a fine piece of equipment
but this idiot that had it on the car didnt know how to use it and he just had some random tune that was supposably "safe" for the car..had no wideband so i dont know how it was tuned..he sold me the car, within a month the motor blew

Well you really cant blame an safc for that.
This was on what? A 5sfte? 3sgte?

so you STILL blame me for YOUR ****-up? I told your retarded ass that it needs a tune..and the ****ing SAFC and I were not the reason you blew the motor you moron.. get it straight.. you beat the car (especially one that is turbo)..you pay the consequences.. grow up and take responsibility for your mistakes and negligence.. do i have to requote your posts about you beating on the car? i might as well:



EDIT:

easy there fellas no need to get rowdy. you didn't kill a human being you broke a motor. I'm one of the most cautious tuners you may ever meet and I broke a FULLY built nissan SR20 motor about 5 minutes into the first tuning session using an SAFC with the wideband attached to the car and every imaginable other guage necessary.
Keep in mind that engines are mechanical and thus prone to failure. In my instance it was a rusted custom water line that developed a crack and dumped all of the engine's coolant on the highway while at WOT 15psi of boost. It doesn't really take much to break an engine.
As far as the SAFC is concerned I don't really recommend it. It has been succeeded by much better fairly cheap tuning options now but If you already have one (depending on which one) It is still quite possible to use it for safe WOT air fuel ratios at boost levels well above factory settings. If you're serious about performance though the SAFC is a joke compared to what can be achieved by a proper setup that can cater to both fuel and ignition timing adjustments for safe reliable performance and excellent drivability.

What about it dont you recommend?

well for the same reason anyone else wouldn't recommend it!
What's the point of doing tuning if the stock ECU remains in complete control?
Effectively all you can do with an SAFC is HOPE for the best power output from the fuel delivery and ignition timing the OE ECU thinks is appropriate given the new "corrected" mass air flow (or pressure) signal from the SAFC.
How do you compensate for changes in volumetric efficiency such as is the case with installing aftermarket camshafts? And even if the ECU does manage to generally maintain your targeted air fuel ratios how do you optimise timing for best power and fuel consumption without the onset of knock? Not to mention the ECUs that do not read an intake air temp signal.
The SAFC succeeded an era of rising rate fuel pressure regulator tuning which was like going from taking a shot in the dark to being able to make an educated guess. Guesswork is still not a characteristic I find admirable in engine tuning.

Guys, Guys, Guys...keep this $hit out of my thread...serisouly...i dont want to hear or see that 5sfte anywhere near my thread...i get so much $hit from people at meets for my car because they think it's that turd and its not even close. it was on every car forum i laid my eyes on in the past 6 months, i cant take it anymore....and art...honestly...who cars why he doesnt like it or doesnt recomend it, obviously he has some research to do on the tool...any tool in the world wont work if you use it the wrong way...the same reason you dont use a shovel to chop a tree down is the same reason you dont use an safc if you dont know what your doing. case and point

anyway...

Yea the SAFC is awesome...like i said we were really conservative when pulling fuel because i dont have a wideband just yet...but that will be next...even with the simple tuneing that we did(pulled a little bit of fuel) the car runs so much better. I really like it and im looking forward to taking full advantage of it once i have a few more supporting mods.

As for the exhaust, consequently its going on tomorrow around 4pm. I picked up (2) 45 degree mandrel bent pipes along with a 3" flange and a 3" gasket. Those were basically the last 2 pieces i needed to weld it up...the only thing i need from the exhaust shop is a 3" flex section and some straight pipe. tomorrow i'll have pictures and video clips up of the new set-up...im pumped!

awesome dude!
be sure to take some good pics!

You say I don't know how to use an SAFC yet soon after you talk about pulling fuel using an SAFC which is technically impossible. Sigh. they say ignorance is bliss. If you plan on installing a 3" exhaust with your current "magical guesswork" tuning technique on that 3sgte you are going to melt those pistons. but then again i have no idea what i'm talking about

You are not going to melt pistons by taking out 10% air signal (which leads to the stock ecu supplying less fuel) from the low throttle map only. The 2nd gen 3sgte is tuned insanely rich in the part throttle regions of the map to help compensate for the terrible top mount intercooler that it came with stock. This is the tune that I have setup on my car (along with negative corrections for the high throttle map, because I have alcohol injection) for about a year now with zero problems.

The safc is a tool for removing fuel and adding ignition timing, or adding fuel and reducing ignition timing by fooling the factory air flow meter signal. Its a great tool if that is the task that you wish to accomplish.

Is a full stand alone better? Sure but it really depends on the application. An AEM or PowerFC in the wrong hands is just as dangerous or even more so than an safc, yet no one blames the tool for engine failure in those cases.

X11billion.
great post.

no camera=crappy cell phone pics but you'll get the idea

from the DP i have a 45" bend to the flex to the cut-out...My buddy chris has to order more 3" stock so it should be in on monday to finish the rest up.

It sounds much deeper...comparable to an srt-4 from inside the car but better

im likeing the way it sounds and i can drive it tomorrow to get use to how it will sound and feel when the cut-out is open...i cant wait untill the rest is on. I noticed that from 1st to 3rd it pulls just as well if not better then before due to the little bit of back pressure the turbo is now getting, but 4th-5th feels a little slower because its harder to push more air. It defintally made a difference though, and the more i drive it the more i like it...just going to take some getting use to

I'll have better pictures and videos up of it later in the week, but for now this is what were workin with

little update..

i picked up an AEM wideband today...hopefully i can have that, the meth, and a boost controler hooked up in a nother week or so and really start pulling some more power out of it

i also grabbed a stock 2nd gen exhaust manifold for a little project of mine...if it works, it will be an incrediable ground breaking feat. for the 6gc community...and kits will be produced for those who follow in my footsteps of more boost

exhaust is officially on...videos and pictures before and after the sonic meet guaranteed...

also grabbed a 20b but that wont be on for a while yet...after the meth and wideband of course of course

good stuff amigo

Found this on tst. the car is coming together nicely, bud! Exhaust sounds great too!

Nice progress bud, I like your enthusiasm. Keep up the good work!
