I am getting an '84 GSL-SE with the 13B fuel injected engine. I heard some people put carburetors on those. Is this worth it, and is it cheap? Fuel mileage is not an issue.

 

it can be depending on what you want it for and if you are going for performance terms or whatnot. i like the EGI system personally but thats just me. throttle response is good and performance is great.

 

y the hell would you do that???

Carbies give a worse fuel delivery. it sorta studders a bit wen u put ur fut down. To My belief efi is by far superior, or y would all cars now days be efi. keep it efi or if u want a carbie, get a gsl.

 

I mean, you can't tweak and tune an EFI system like you can a classic carburetor. They probably don't make carburetors any more because the government put a restriction on gas mileage efficiency. Anyways, it's fun rebuilding carburetors and getting them to push through a lot of horsepower.

 

The stock fi system sucks on se's. And the AFM is a major restriction. Swapping over to carb actually nets a pretty nice increase in power. And just about anybody can learn how to tune a carb. Not to mention the fact that they look much better, or at least cleaner, as a system.

I like fuel injection too, just not the stock crap.

 

By the way, I don't plan on putting a carburetor on my 13B. But I do still prefer carburetors. Besides, you can upgrade to larger, more powerful carburetors for way less than EFI systems (or EGI in this case)

 

So, how expensive is it to switch over? Is it a complicated process getting it setup right?

 

ABout 800 bucks or so should get you everything you need. I'm running an 86 motor that I changed to carb, and I dont regret it one bit.

 

^you can do it for less than 800 if you find some good deals. I'd say as little as 600 if you get lucky. 800 is a good estimate.

I see a lot of RB carb/intake manifolds go for 400-450 as a combo. Then all you need is a fuel pump and regulator. You can actually get a way with just a regulator but you would be bypassing most of the fuel.

 

I am also running an 86 motor with the racing beat setup. There are a couple good choices, rotary shak set up which I believe is a webber, and the holley set up. I have the holley and I as well don't regret it one bit. I can take about any second gen aroudn here that has about the same mods as me, without the carb. SO I like it alot.

 

Actually I think you have to buy a carb fuel pump, you can't just bypass the fuel with the fuel injected pump, atleast I wouldn't. So you would need the carb, manifold, fuel pump, FPR, Fuel injection block off plate, and a few little things, like an inline fuel gauge would be good.

 

You can but you will be bypassing a lot of fuel. It is good to use the stock fi pump if you plan on going blowthrough turbo. The stock pump is up to the pressure requirements that you will need (for rising fuel pressure directly with boost pressure).

Do SE's have their injectors in the manifold or are they in the center plate like a 2nd gen? I know the SE's only have 2 injectors.

 

The SEs use the ceter plate like a 2nd gen.

 

For about $850 you can wire up a Microtech, use the same intake manifold, same fuel system, and get all the tunability that you want. Why not upgrade to modern technology since the costs are similar? If you want to get really cheap, use a megasquirt. Carbs can't adapt on their own for temperature and elevation changes.

 

because to get it donr right you gotta pay a good tuner, and that costs big bucks. EVERYONE forgets about this.

Thats why carb is cheaper.

 

I have a carb and I use the GSL-SE fuel pump. It works if you use a mallory return style fuel pressure regulator.

 

I haved swapped a carb on my friends 87 also, we used a 48 IDA, the engine bay got way cleaner, now you can actually see the engine, and it runs better than the crappy fuel injection. im all for converting to carb, we noticed a small gain in power as well.

How could you go wrong with that?

 

Nice

 

What about if he doesn't know how to tune a carb? You can learn both. You would still need to pay for someone to tune it. EVERYONE also seems to forget about proper carb tuning. Irrelevant excuse.

 

nice carb knight, my friend had the same carb on his 1.1
anywho, id say deffinetly go with the carb and free up some ponys, I just changed my 84 gslse to a 44 webber and right now I havent got to tune it (busy w/ body work) but for the one gear that I have gas, It runs alot better and faster than the fuel injection. the carb setup cost 900 bucks though, but the good news is that each one of your injectors from your fuel injection is worth 100 or more to a 2nd genner that wants a bigger primary. or you could sell you injection as holw BTW I have a fuel injection setup for sale if anybody needs one.

I saw in a forum a couple of years ago that A guy just put a delardo carb on his 85 gslse and racing beat exaust and he ran a 14.4 but keep in mind LOTTA WORK.
