Someone Plaese Help The Dummy!
OK, I am a dummy when it comes to chosing the right stuff sometimes. I just picked up a used Racing Beat intake for a 12a for 90 bucks. I think I got a good deal. The only problem know is chosing a good carb for my setup. The engine in my car is a Mazda replacement engine with appr. 25K on her. I had Stan at SDJ Motorsports go through the stock Nikki and I have a cutom APC exhaust with a Pacesetter header. I know everyone has thier opinion on what is best to use, but I am trying to seek some guideance on a tight budjet right now. I would like to try and go with something I am fimiliar with , but I want it to work!

honestly, if sdj went thru the nikki then i would rock that out. as i said in the pm response, if you get a holley you need to tune it. if this isn't a problem then go with the 450cfm 4160 and mess with it some for drivability.

Ok, everysince Stan at SDJ went through the Nikki it has always had a stumbling problem when I floor it in 1rst gear. It just acts like it don't want to take the gas. Stomp it in 2nd or higher, it seems to act fine. I was told to block off one of those stupid little vacuum control modules ( the 4rth one I think) to keep it from shotgunnig between changing gears. Every since I have done that it has always acted wierd. I just thought if I went with the Holley RB intake setup and done away with all that emmisions crap and the smog pump and all, I would pick up a few more ponies and drop about 10 to 15 pounds of crap off the engine.

that stumble could be ignition related, maybe not the carb. then again i dunno what they did to it. SDJ is awesome tho so i'm sure it's all good. taking off the rats nest alone could possibly cure your problem. it could be something as dumb as a vaccum leak. hard to say off the bat.
switching to the holley could net you more ponies.... IF you know how to tune it or have someone that knows how to tune it. this is why people bash the holley carbs because they get it and when it immediately doesnt work they are mad and blame the carb. you will have to take off the float bowls and dig in to get it driving nice and right.
if that's not your cup of tea then rock out what you have now. just do the rats nest removal.

Thanks for all the info. I know what you mean abaout all the Holley bashers out there. My last pro street project was a '84 S-10 with a 355 smallblock, turbo 350 trans, 9" Ford 3.55 gears with a Weiand Stealth intake and a Holley Dominater track prepped carb. Pulled 325hp at the rear wheels. I wouldn't have taken nothing for that Holley that was on that Monster. Let me show yall some of my handy work.

Airflow is my life
So the intake manifold you got is for the Holley for sure right? If your gonna go Holley, then keep what you got and save for a RB Holley carb. Since youve removed the cats, strip off the emissions per the tutorial. Possibly the spark advance solenoid for the ign isint working right. Thatll come off with the rats nest and be straight plumbed. Your stumble is probably the accel pump though. Pull off the air box and look into the carb and see if its squirting as soon as you move the throttle. They arent tolerant of misadjustment.

agreed, if you are set on not using the nikki then save some bones and get the holley from Racing Beat. it will bolt on and go no problem. you can do some fine tuning to get more umph from it but i've messed with one and it definately was a step up from the nikki. until then... listen to the banana
