first i'd like to thank wackeyracer, jeezus, cb performance, and my local Lowe's. The setup is a rb dellorto 48mm dhla with a one piece sidedraft intake. I got the carb in fairly good condition at a great price, pulled it apart and rebuilt it and rejetted it. polished the lid. got the intake, wirebrushed it, tapped the mop barbs. just waiting for racing beat gasket in the mail for it to go on. any good step by steps for putting one of these things on? step by step?

If you needed a gasket I had like 3 sitting around here lol. Sorry I forgot to ask, I coulda thrown that in the box.

slate84

haha, its cool. i got it from racing beat and tom (from rb) called me the next day cause somehow the 48,000 dollar 3-rotor got in my cart along with the 7 dollar gasket.

your next step is to add some 4.44 gears.

4.44 gears are good for drag racing bad on gas mileage right?

not really. good for street use and freeway as well. you should try riding in my 75 RX-3 with 4.78. Suck on the freeway

I had a Dell for awhile, it was nice, but not really my cup of tea.

It sucked for low end, but on the top end that bad boy would scream!

What air filter set-up is that?
I have the RB foam filter that looks dirty very quickly.

I'd like to know about that filter also. I just tried to order a new foam cover from Mazdatrix and they are no longer available.

Take the measurements of how big of a filter you can get, when I bought mine the first time, I got it too big.

dellorto is a nice setup I had 1 on my 80 street ported 12A.

slate84

like he said its a k&n. any input on the throttle bracket?

dean7

I just had mine off the carb! Did you want a pick of it on mine? With mine, the bracket is attached to the bottom of the air filter assembly.

Brookings isn't to far from Omaha, ever come down? I have seen it on my yearly trip to Park Rapids.

Oh and for a step by step.. got to gruntled.com they have the original RB install directions copied.

dean7

LOL well I got a set of 4.444's from mazda trix years ago, when I tore apart my gears... Made first gear feel like a truck gear, only used it from dead stops and racing, it sucked for autocross sort of. It accelerated great but it seemed like the gearing always screwed me.

I noticed a bit of a performance increase (5th and 6th ports were closed) enough to keep up with a 12a with mikuni vs my gsl-se with headers. Honestly though, id do a lighter flywheel first, but its nice taking the pumpkin out and rebuilding her.. I think I can recall driving on I-80 doing the speed limit of 75 and being at like 3,500- 4,200 rpms in 5th gear didn't want to speed lol.

slate84

a pictue would be amazing. thanks dean7. been down there a few times, ill hit you up if i come down in the future. ps, what can i expect going from stock with exhaust to adding this setup?

slate84

so how should the ideal mixture screws and ideal speed screw be set when first mounting it up?

dean7

Screw the mixture screws in all the way, then unscrew them about 3 1/2 turns, adust the idle and accel screws from there till you get a good idle. Then time the car, then mess with your carb again... And you can expect to spend more money on gas and some oomph.

slate84

any ohter screw settings i need to know, also, i can see how the bracket is on the gruntled instructions but does any one have the measurements of: inches back from base of air cleaner plate to even with braket(blue arrow) and from level with the filter up to center of the throttle hole (green arrow). also hole size for cable on the braket (purple)?

I have seen so guys use an alternator bracket reformed and used as a throttle bracket. Not the best look but it worked very well.
From what i remember, you bend the braket into an "L" shape and bolt it down to the rear plate were the flywheel cover is. If I find a pic of some cars at the track with this "custom" bracket I will post it for you.
