More power but no engine swapping?

[BootMachine]

JEGGS has the same thing but its more expensive and IMO less "cool" to look at. They do the same thing though!

Gary,
 I can't use the seats, well, i could but the pattern and colour are wrong, my tan is darker (or dirty ) and i have a racing stripe on my seat. thanks for the offer though

And to the rest of you, thanks for the advice, you've all givin me a lot to think and decide about

I Have a 84 se 2.5
 I have install a new hight performance coil in wires
put a TBI kit in the TB body
ran several gas cleaner& carbout
I also fond running hight test gas make a big difference

Right now in running very well power out put is great keep up with most modern stock 4 bangners


If you have any ? about any of the above email me

Whats a TBI kit and where is the TB body?  and before anybody flames me, i'm serious  *sigh* what I wouldn't give to have taken a engine class back in HS when it was free

[Rebel]

TBI is check  this page http://www.secureleadercom.com/fsstore/initsite.asp

there are lots in the junk yard for 1/4 the price

you know.....the rice boys rant and rave about MPFI but really...when they run FI on the little Honda zingers they all convert to TBFI!

I think if you too the stock Fiero engine and added a fuel control system, CAI, velocity tuned exhaust and port matched the head you could get some nice gains...oh you will need an ignition system with that too! Take a few thousands off the head as well.

SAFC (air fuel controller)

dude, our ecm is too old to handle these things!
and f.y.i the only thing they are good for is to control when and where ur v-tec kicks in...any other useage is mainly asthetic (spl?)

also, (correct me if I am wrong) but our comp will just monitor the tbi functions, watch the o2 sensor and vaccum/map sensor info...if they read wrong, a check engine light is flashed...and reset just as easily

no...the V-ACF is for Hondas. THATS the one that controlls the V-Tec crossover.

The SAFC is a very simple computer that modify's signals from the Map sensor and o2 sensor. It has a fancy display and memory so you can store settings, play back settings and play around with it in real time.

Both the VAFC and SAFC tune your A/F mixture but a wide band o2 sensor may be needed depending on the resolution of the stock one.

The VAFC is for Honda V-tec engines....its an SAFC with an extra wire for the V-Tec solonoid!

The SAFC is universal...if it has a map and o2 sensor....SAFC will work~!

see this is where you are confused.....

the o2 sensor and map sensors are all good and fine, but the ECU isn't even what you would call obd1...even the machine to check the codes only reads if the parts are good or bad, it's not a numbers game like the new vehicles out there (bmw in particular)

or mebbe i am right out of the ballpark on this one....(although I have NEVER even seen a 2.8 Camaro with any more ^electronic mods than maybe a chip...)

also....the only way to "tune" the air fuel mix is if you actually do something phisical i.e. remove/adjust some vac lines....

remember my s-10? I was bitching and complaining that the idle valve is SEALED .... that is the same for most (if not all)

I do not see where the problem is I have two PCM's one stock and the other for racing. OOOPS wait a minute I forgot some of you are still running the original under powered poorly designed systems the cars came with. HEE HEE don't you just hate those smart asses out there. Dan

[BootMachine]

well the signal comes from somewhere to fire the injectors.

Change the pulse width OR...change the fuel pressure....but pressure / delivery is not linear so I would leave that until I have money !

I dont know everything though...I have NEVER worked on a fiero!

Runaway thread???

Here’s an idea.  Instead of swapping the engine you could buy a Cadillac STS (insurance right off, side or rear impact only) and swap the body around the engine.  I hear that it’s much easier to swap a body, than an engine.

Just a thought??…and by the spring there should be plenty of info on this sight to help you obtain your goals (northstar goals that is).

Seriously though…I’ll stand by my original suggestion.  Cut the chassis weight, and or add a turbocharger (used even).  Just don’t forget to match the turbocharger with your engine.
