Add turbo with B2000 carb engine?

Have anyone great sucess using turbo from Mazda 626 with stock B2000 carb engine?

I aware it may need add one custom fuel injection or turning more rich to keep away from burning too much lean.

Maybe 5-15PSI boost would nice gain little HP power!

Personally I would not try it with a stock carb. I would install a weber first.

Install the a weber and crank the fuel up. Then the main things you have to worry about is away to cut the vacum advance off while under boost. Im also gonna start this project as soon as i can find a 626 to gets parts from. And K6 should be able to confirm this because im not sure but i think you can use a MSD box whith a built in timing controller for boost to disable the vacum advance.

I forgot to mention you will also need a fuel pressure regulator that is vacum controlled so as u make more boost you will have more fuel pressure to compensate. Im sure theres a list of companys that make them but everyone i race with runs Aeromotive regulators.

you might be able to make a primitive retard ignition system by reversing a vac advance unit? won't be able to have much advance outside of boost, but would be able to kick a couple degrees out of it when the pressure comes up in the line? i haven't mucked with a distributor much recently, but im sure its possible, maybe also with a reversed vacum unit, a t valve that can bleed vacum but hold pressure?

first thing tho, throw on a weber or a holley, or another carb from maybe a slightly bigger engine.

You might be able to do that not sure never tried it. yeah but definitely you will have to get a bigger carb, get a holley i hate my weber its a pain in the ***. you will have to jet the crap out of it and then work your way down to the right mixture that way you dont bake your pistons

There are a few ignition units out there that will take retard with boost. Mallory hyfire has one with a sensor up to 1 or 2 bar I believe.

That is the route I am going to go. Also I chose the Dellorto DRLA carb because it could handle boost. However I always seem to get side tracked by something else(rearend,bags,transmission,clutch,aluminum flywheel)

I wonder what will side track me this year? Anyone else experience this.

All the time especially when you have 3 bs 1 chevy truck and 1 chevy car never heard of the dellorto carb are they specifically for our trucks or are you adapting it to work

he adapted his to custom fit, its pretty big. i usually get side tracked by life stuff when truck stuff needs to be done, then tracked by truck stuff when life stuff has to be done lol.

yeah lol i have the major problem of running out of money lol. is the carb 4 barral or just a really big 2 barral.

two barrel

two very large barrels

my avatar picture is the dellorto on my truck

Back on topic the stock distributor has both a mechanical and vacuum advance and it cannot fully advance without the vacuum advance being hooked up so there are two simple options. The first is you hook up a boost switch or some sort of pressure switch to a vacuum solenoid that turns off the vacuum advance at a desired boost, this will cause the distributor to retard to the maximum mechanical advance setting. The second method, which I've seen described in a book is to place some sort of pressure differential fitting in the line of the vacuum advance. This is done with a T-fitting with one of the lines having a very small restriction. Changing the restriction size adjusts when the boost negates any vacuum on the advance.

You also must run a carb with closed cell floats, brass floats will not work because the increased pressure differential from the boost will cause them to crush.

Also inside the carburetor you will need a larger inlet needle and seat to keep up with fuel demands.

Unless you are rebuilding the engine specifically for boost you will need a good intercooler to ensure you don't cause damage with the higher compression ratio.

yes i would recomend a wideband too to be able to tune it in decently

could you source an intercooler from a rx7 or 626.

RX-7 intercooler is designed to sit on top of the engine and be cooled from a ram scoop on top of the hood, not the best choice. If he is not lowering his compression he will probably need a better intercooler than what the 626 came with since it would be more prone to pre-ignition/detonation.

ya the stock is 8.8 and the turbo is 7.8.

8.8 is still fine for turboing, but no more than 9psi, make sure there is lots of fuel, and like k6 said a decently large intercooler to help as well.
