switching to carb

[95whiteprix]

Just curious, if you were to switch to a carbureted intake would you be able to remove the computer from the car. As far as I know the computer controls timing and well to sum it up everything the motor does. Is there a way to change timing other than through the computer. Also would there be a way to to still run DIS without the computer.

Personally I think a carbureted TDC would kick major ass for those who do not have to drive them on a daily basis.

I just think it would be so much easier to get power out of a carbed TDC.

Anyone know what all would have to be done.

A lot of stuff!!

Hey 95whiteprix,

You would be looking at a HUGE project. You would have to first worry about Casting a new intake. For running an ignition MSD and AEM have stand alone DIS Ignition systems. That is a project that can be done if you have lots of money to throw around. It would be neat to see. You would need a new hood LOL.

Not to mention the loss of those lovely long runners.

If you're having trouble with an engine swap, just switch down to a 91-93 ECM and have most of the garbage ripped out.

I'd say the the ONLY real way you'd actually gain in a setup like this would be to use a custom high-rise IR carb setup, or a tall tunnel ram.

Otherwise, you're wasting your time.

Carb?

[SappySE107]

There was a setup to do this on ebay 2-3 years ago. Its absurd to me to even contemplate taking this motor and throwing a carb on it.

The performance bottleneck on the TDC / DOHC is cams, not fuel delivery.

Even if the cams were available, it would be easier to make big cams streetable using EFI than with carbeurettion.

Carbs are dead. The only people using them are relics.

[ryan.hess]

Somebody should slap a carb on a 2004 Ferarri F360. I'd pay money to see that.

[95whiteprix]

Maybe i'll just save up 600 bux and hook up some nitrous in my car.

Do agree on the cams. Any motor would kick ass with good cams, but i'm a poor bastard and have to stick with the small tweaks for the nexts 2ish months.

[Jakemetz63]

And please dont run nitrus with only "small tweaks" done to your car. Know your stuff, dont be stupid and give it a 100 shot. Research Nitrous before even dreaming of hooking it up.

[SappySE107]

eh, 100 shot wet would probably work ok. Spark might need to be retarded a couple degrees on the stock chip though but other than that I think it would be fine.

But thats another thread discussion:P

Let's see, some Canadian did a 50 shot on an LQ1. And blew it to smithereenies! There is a thread somewhere, I'm just too lazy to find it....

But IMHO, I'd wait a while, lot of good info has come up on the LQ1 in the last year. And more in the works.

Carb one? Why not? Since you would have to have a custom intake anyway, you could run a magneto off the oil pump drive. Deleted the PCM, and all the sensors that make it run in a normal vehicle.


Crank, spark, and go... Yep.

I'd like to see this done, just for the hell of it. Even on stock cams.

Manual trans only....

If you don't know what you're doing even a 25 shot will blow up your motor.

[Fierobsessed]

Cut part of the head out of the way, might be able to run a distributor too..

But still IMO, Fuel Injection is the only way to go.

[Mach10]

Except for that water jacket right over the oil-pump plug. No way to clearance a distributor... No freakin' way.

You might be able to put together a front-distro like on the LT1s...

stand alone spark management. i've never been in a tdc motor, wont fit easily into my car, but i want one anyways. i think a carb setup would be cool, you could try other ways, like making a plenum sort of manifold for a single large side draft delorto or weber carb. but as stated before, you have no runners, at least not anything worth calling a runner, and consequently no low end power. maybe if it was a split plenum design with 1 barrel feeding each bank (i did say large carb right?) the "runners" would seem longer and it might run more stable or have better low end.
