hey guys, so what are the biggest advantages to having a carb instead of keeping the fuel injection on gsl-se's? more tuning ability? power gain? if you want turbo, is it easier to set up when you're working with a carb? thanks

I believe the main thing is it's just simplier. I believe all the point you stated are good for a carb.

more power and more fuel consumption!! i like carbs, always thirsty

so the more you port your motor, free your exhaust and intake up, etc...the more fuel you can use so a carb is less "restricting" when it comes to fuel flow?

The stock EFI system is ancient and pathetic. Its very restrictive, and that alone is why racingbeat and other companies sell their carb kits as an intake upgrade for the GSL-SE.

WELL... on that last remark, what Racing Beat does say is that their Holly 650cfm unit on their proprietary intake manifold WILL NOT produce appreciable power increases as compared to the stock Bosch L-Jetronic based EFI on the SE's.

That's saying something.

The points that you make about carbs being simpler are true to most degrees - there's less 'wiring' and less 'computer' involved in making them work well, but carbs require building and tuning along with precise fuel pressure management to get good performance. In contrast, what you gain for the technological equipment that EFI takes is reliability, fuel efficiency, throttle response, and overall performance.

Some will argue that EFI is less 'tunable', but if you're willing to spend money on a Dellorto or Weber intake system, jets, secondaries, air control valves, bleed valves, and the time to learn how to tune these carbs, you could spend the same money and be done faster with a programmable EFI computer for your stock injectors. Hell, go all out and 'upgrade' an SE to the 2nd Gen 4-injector, staged system and you'll probably still come out ahead in dollars spent, time invested, and final performance.

To say that the stock SE fuel injection sucks is shortsighted. For it's day, the Bosch systems worked great - Porsche, Audi, and Mercedes were all using the same 'airvane' type airflow meter assembly, and it wasn't until technology moved up to 'hot-wire' that performance really took off. If you know what you're doing, either system can make power, but EFI remains an extremely reliable and consistent method of calculating and delivering the proper A/F mixture.

Today, no major car manufacturer (sports, luxury, touring, whatever) develops and markets a carbureated vehicle. What does that tell you?

That they don't appreciate old school powah?

hahaha awesome carbs and 1st gens are like two peas in a pod. i wouldnt have it any other way. but i'm just a fatty who loves cheese.

cdrad51

Seriously though, to give a point of comparison, I bet you I can beat any fuel injected SE that is not streetported or turboed, no matter what other mods it might have. True, my engine is streetported, but that should balance with the fact that the 12A is smaller.

ok.. let's race cdrad. stock SE vs. your modded 12a

cdrad51

pfft. Anytime. what you got boy.

hey nick1 - just a pet peeve ... Niagara

anyway, the power increase is the biggest deal and it also simplifies things a bit. i'll agree with that to an extent if all you plan to do is boost your stock power up a bit for more fun. however ... and this is just an opinion so treat it for waht it's worth ... in this day and age when fuel injection is so relatively affordable and widepsread, i think if you're after serious power and more consitent reliability, then a carb-based fuel injection system is the way to go.

carbs produce the same power and use more gas as the gsl-se EGI, along wiith having to pump yer gas pedal to start the car and having a higher chance of flodding the engine..

im EGI all the way....
