Carburated LS1... who's done it?

I've seen a 924 with a carb'd SBC, and i think 1 944 on youtube but i'd like to see some more pics of it done.

I'm seriously concidering going carb to keep cost/wiring down.

I know a cowl/scoop would have to be added to the hood.

Let's see whats out there.

Thanks

the stock ls1 harness is great, as is ecu and intake, removing the VATS via odbii is easy,

By the time you buy the carb/intake, i doubt you're going to save any money. You'll lose fuel economy and driveability too. Wiring is going to be more difficult with a carb setup because you'll have to figure out how to make the ignition work as a stand-alone.

I used to love carbs and i still do, but there's just no comparison unless your only care is WOT performance at normal operating temperatures. In all, more money and more work, with no perceived benefit.

wiring is NO issue with a carb... look into LS1 carb options out there:

that kit is $700, carb is $300... done

LS1's are ALOT more expensive in Canada then the states... Wreckers wants $4000, on craigslist they can SOMETIMES be had for $1500 both without wiring harness ($200) or ECU ($100), and i'd still need a MAF and possibly cable TB along with whatever other little things

I've thought about the 5.3L L33 option, but then i'd still need an LS intake ($300), front accessory brackets incl. water pump, and the harness and ECU again.

Carb just really does seem more cost effective
Selling the manifold could pay for most (if not all) the carb.

I bought my engine in the US, even inclusive shipping all the way to norway, it still cost less than 3000USD

Hello, what part of Canada? I am in Winnipeg. I have all my parts shipped to a parcel post in Neche ND, and it saves a huge amount of money.Check into it. it works great.

Hey 89VW, I would do that swap in a heart beat, if I didn't already have an sbc swap! The simplicity, reliability and savings are unbeatable. Theres a u-tube video, just search 911vette and look for PORCHE on the right. I've since had the hood painted to match and it came out great. The handling was off as the sway bar bushing popped out fron the vertical body mount, kinda of fun though. Good luck on your swap either way!!

Wait, why would you want to sacrifice gas mileage, power, and longevity again?

cause a carb will make more power than any stock ls1 injector, easy install, less money, and honestly if you're gonna drive a car like that, it's kind of silly to worry about mpg! Face it dude the old leaking toilet still rules! (in this application)

Make more power? Really?

The only benefit of a carb is the price. That is it. In the long term, you will make up the difference in gas and in engine wear.

NASCAR is going to EFI for a reason.

Your math just isn't adding up to me. What do the accessories have to do with the carb? You're going to need them either way. The only difference is going to be the manifold and the wiring. With the prices you listed you're looking at ($200 + $100 + $300 =) $600 for EFI or ($300 + $700 = ) $1000 for the carb setup. Add to that that the EFI > Carb, and it's a no-brainer.

Now if we were talking an SBC here, it would be a different story since good fuel injection was not found on the SBC.

I'm in Edmonton and starting to see 6.0 L engines going for $600- $1000 complete sometimes with computer. With the stuff I had lying around the shop I figured an extra $1000 going fuel injection but I'm glad I did, it was nice to keep it under the hood. Had it out today with the 5' snow piles on the side of the road. People are still wanting more for LT1's than 6.0 L LS's here. 5.3's can be found for $100 now.

Starting a Turbo Mitsubishi project for for learning purposes. Looking for a budget 400HP and started with 2 cars so I now have new injectors of an adequate size for the Porsche as I had to buy larger ones for the 2.0L. I wouldn't do another SBC to LT1 intake conversion. Works fine but a lot of work.

However you do it, DO IT... It's worth it!!!

Is that for the L33 all aluminum 5.3L??? If so you have a link/phone number of a place to get them?

It's probably for the LM7 iron blocks. You can also look for the LM4, which is an aluminum version of the LM7.

I just dont get the carb fetish, I just bought a 1969 camaro RS with procharged bigblock, its SO getting efi done to it when I get the money. the milage is INSANE in a bad way. it used to run 1050 dominiator, down to 950's now.. but still.

remember though... those prices i gave were for ALL brand new stuff on the carb side and ALL used stuff on the EFI side..... If i found that carb stuff used im sure it would be $500-$700max

THAT's your problem, not the carb

(5 liters) per (10 km) = 4.70429167 miles per gallon

it used to do (10 liters) per (10 km) = 2.35214583 miles per gallon

but it should be able to get down to (2 liters) per (10 km) = 11.7607292 miles per gallon

seeing as our gas price is alltime high, and aprox 8-9USD per gallon now... well efi saves it self easy!

either way, i'm more concerned on seeing pics of different hood styles/engine bays of carb'd ls's in 944's.

Anyone have any?

1/4 the way down a pic of a 944 with a scoop

i'm not looking for pics of full blown race car hoods...

hey closest i have found for hood wise

Hey 89, carbs RULE! Don't fall into the trap of injection... There is nothing better for visual assault than a ancient piece of potmetal sitting proudly atop that manifold. Take your injection and give it to someone who wants all the headaches of expensive sensors that fail and such fun and games. I roll my eyes every time i read about "electrical issues"... and don't tell me how great injection is-I'm not drinking any more Kool-Aid.
DO THE CARB! Long live the metered fuel leak!

haha thanks man!

I still want the phone number to these places selling 5.3L's for $100.... i searched car-part.com and the cheapest i found across Canada was $600

Hey man! I thought you disappeared! When I first decided to do the swap; I realized how overpriced every engine was in Canada. I was going to use a truck engine; then I found a complete low KM LT1 from a Camaro with all the wiring, accesories, msd distributor, msd ignition and hypertech power programer for 1000$ on KIJIJI.ca. I would just keep your eye out for something on there. The wiring really isn't a big deal, I was able to do it in one weekend. Just take your time and triple check everything you do. My car should be ready in the beginning of the summer. If I get it so it's drivable, I can stop by since your only 20mins from me. I can't wait to drive it!
