Hello everyone. I'm wondering if anyone has used or has any knowledge of anyone using a holley setup such as racing beats. Let me know what you know. Also, does anyone know where I can get the upper manifold for the 6-port other then from racing beat?

ive never used one but i do believe that it take some fine tuning to get them running right. but then so does forced induction so i guess either one is going to be a pain. but with turbo its all computer mapping your engine paramaters and having the right equipment, so my guess for carbs it would be fine tuning the equipment physically and puttin it on a dyno alot. but im not to sure so good luck on your quest for knowledge. https://www.nopistons.com/forums/pub...1047683329.gif

I just got my 6-port into my 85 and I am running a holley carb set up from racing beat. It is easy to installl and fairly easy to tune. I am just waiting for my timing to be fixed, I just didn't get to it yet, so its not running the greatest yet. But when It does, I'll let you know.

thats awesome red12a ive heard that those carb systems can pull mad hard. please let us all know how it goes. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

are talking about carbing a 2nd gen? WHY?

i am in the procces of putting together my 13b and putting it in my gtu, i am useing the raceing beat dellorto 48mm sidedraft carb, i put it on my 12a (aside from the constant flooding) it made the li'll basterd screem, so hopefully it will be good on my 13b

I carbed the second gen motor because I am putting it in a non fuel injection car and it makes the swap a whole lot easier. No wiring or anything to mess with. Thats why I did it. and makes more power than stock. I will let everyone know how the swap goes.

Wow, I now have incorporated carburation into my future car plans!



question: Is some kind of CAI available for that? Or would you not want it for some reason?



Also, I'm familiar with how weather/temperature affects carbs from motorcycle riding. My Honda has carb heaters; are there aftermarket carb heaters available for this setup?

to red12a7,

awesome,I love 1st gens, your doing exactly what i want to do. unfortunatly, i have to live with my 87 for now. it's not all that bad though! look forward to hearing from you when its done. i've got this wacky idea of spinning the motor about 11,ooorpm and throwing in gobs of fuel from a double pumper. a few more questions. are you using a 4 or 6 port. everyone says go with a 4 port but i think a 6 port would have better manners on the street. if you don't mind, how much did every thing cost( intake setup, fuel delivery) thanks man! https://www.nopistons.com/forums/pub...IR#>/boink.gif

A small double pumper with a wideband in the tailpipe and a readout on the dash would be very nice and easy to jet/tune. 11,000rpm requires a specially built motor and about 120psi of oil pressure. A stock 13b will spin 11k rpm......only a few times though.

usually you want the coldest fuel possible, people even

put chillers in thier cars that hold dry ice and the fuel line

goes thru it. Heat no good as you can get vapor lock and what not.



Maybe those carb heaters on your honda is something for cold

starting only?

yeah, that's what I was thinking...do the car carbs have problems in cold weather?

pbrx7-I have a aftermarket 6 port intake I used on my 13bna with a Holley if in need. I've used racing beat, demon carb,webber, and finally a custom 600 cfm dual pumper Holley built by Ty at TPC Racing. I've gone through the different power valve and no power valve and center pivot float bowls because in corners you lean out. The webber had great power but it would run evenly at a steady rpm IE driving on the hwy. Demon was the best out of the box and they were very helpful at Barry Grant but have a tendacy to leak on the thottle shaft and I had to get mine rebuilt twice by them. My double pumper I had built bolted right on and ran prefect. I am going to richen it just a little but that is me and it probably does not need it. I welded one air/ fuel bung in each header pipe with a one wire cadillac probe(price) you do not an expensive one then a autometer for each and now I know what the engine is doing at all times. I'm old school and do not want to get into electrical unless I have to. I hope I can do the picture right since I'm not computer friendly. Good luck.

Mrmazda,

I followed every thing you said up until air/fuel bung? I don't want to sound stupid but I'm not tracking here. Also, from what your saying I'm on the right track with the double pumper. What is the max size you would use for a good performance/streetable setup. Also, what about porting? I realize this setup runs all six ports all the time. Is it nessecary? I'm afraid of opening it up to much. Please let me know what worked for you. What kind of shape is your intake in and how much do you want? And finally, thanks for the info. You and I would get along great. I know the fuel injection on my car because I've had so much trouble with it in the past. Now it's in good working order, better than the factory had it, but I still hate it!

i believe jay-tech also makes or made a 6 port intake manifold, go with any one of the, i use to have an 84 gsl with a bridge holley setup and let me tell you best NA setup ever!



All i did was a 13b rebuild, used turboII side housings( you can also use 12a side housings they are 4 port as well but then u have to relocate the motor mounts) because 4 port is way better to port period than 6 port. Bridge ported the side housings, real good exhaust port, got the racing beat intake manifold, holley 650 rejetted, and i was shifting at 9800 rpm doin 13.8's and that was with stock rubber and a 3.90 diff..i would done the same setup on my 91 but i want to try and fine tune this fuel injection crap, you know use an s-afc with injectors pump and dyno run it, see which makes more HP

air/fuel bung = place where wideband o2 goes?

Bung where the o2 sensor goes -yes. The intake I have is the jay-tech and it is brand new if I did not know I used it 3 years ago it would pass for new. I do nt remember how much I paid for it but I must have gotten one of the last ones before they switched into another field. At that time I just had normal old street ports but bigger than a 650 double pumper is overkill and probably will do you more harm than good. The holley I'm running now is boost referenced and has mechanical secondaries here is a pic of the old demon carb on the motor I will take a picture of the holley when I can borrow my sons camera.

mrmazda,

so basically your saying run a o2 sensor with a air/ fuel gauge for each rotor? What is boost referenced? If your intake is for sale, let me know how much. Gotta go back to work. Maddiannuyawk, thanks for your help.

My motor is an 86 6-port, someone asked. It is running really really good. Lots more power than the 12a. I can't wait to take it to the track. I am still having a fuel problem, still needs figuring.
