i'm looking at an 85 gsl with 74K on the clock.... but it needs a carb.. i want to ditch the stock carb in favor of a holley... my question is.. why is the holley from racing beat so expensive? i mean.. can i just get a carb from summit? or are the racingbeat ones "tuned" for a rotary? i just cant see spending $500 for something i can get at summit for $250.. tell me if i'm wrong here...

They prepare it, but I got one from Speed Shops and threw it on there and had no problems.

I never tuned it, but it ran okay out of the box on my street port 12A.

The Holley part number is 0-1848-1 I think. That is the one you need that has the fittings and stuff on the correct side.

thanks much

They mod it cause its mounted 90 degrees from its designed location. What exactly they do I dunno, but Im sure center hung floats and stuff like that. You could have stumbles comming out of turns and stuff like that if its not set up right.


Is your motor ported? If not maybe you should think about a modded Nikki? Hell even if it is we can build one for you. PM Sterling or myself if you want more info.

claytonsmith

well i havent actually bought the car yet.. and yeah it comes w/ the stock motor ( only 74K miles).. and one w/ an agressive SP on it.... the reason i wanted to go holley was to eliminate the rats nest and emissions crap... i hear nikki's are quite problematic.. any truth to this? and can you use a nikki and do away w/ all emissions etc??

thanks to all


i have to sell this saturn i have before i can get the RX-7.... hmm

Well good luck getting rid of that saturn! Yes you can do away with the rats nest/emissions crap while still using the nikki.

ok.. since i know approx. squat about carbs and rotaries together.. whats an average cfm requirement for a 12a?

the carb that pillage recomended is rated at 465 cfm i think. is this adequate for a stock/SP motor??


thanks

Pedestrian X

Yup, 465 would work good for a stock port, i have also heard of sumoen using a 600 cfm on a stock port. i dunno muchy about holleys thoguh so cant really help ya there other then that

claytonsmith

ok ok ok.. welll a local guy is telling me that a webber is the way to go.. he says they're uber reliable... is this true?? i am afterall..new at this rx-7/carb deal.. please let me know what the most ecomonical/reliable way to "re-carb" this car if i get it is.. right now.. it starts ok.. and idles fine when cold.. but when warm.. it doesnt want to stay running unless you help it.

any ideas?

p.s.. i appologize for being vague.. i'm just trying to see what options i have

claytonsmith

anyone?

webbers are not soo perfect for street use, more for racing, BUT have been used. It seems to be that the BEST choice for a daily/casual race car is a holley. More "drivabillity" so to speak.

I got the carb for $250 and the intake for $190 and made it work. The only thing is i did have to adjust the idle screwes when i got the carb. It was way too rich and blew up my stock muffler, that's because it was adjusted for a v8. Also the intake manifold has to be ported a little bit to make the secondaries open up all the way or you can just put a spacer in there. Another thing is i think if you change your primary jets for 64's on a stock 12a it would work better.

I don't know man, i have to disagree with you on that one. Webbers in my openion are better for street because they don't bog out in turns and make more low to mid range power. Holleys are better for drag/street cars.

I have the Holley setup that RB sells, and I've also used a Mikuni. I like the Holley better, cause it DOES get better gas mileage and IMO, there's no difference in the two at WOT.

Also, the Holley for stock port is 465cfm, 600cfm for the streetport, and 650cfm DP for P-port.

dude,
you can eliminate the rat's nest and still keep your Nikki. on a stock port engine, it really doesn't matter what carbie you use, you're still going to run into a HP wall because of the ports. you mentioned something about two motors, one is a streetport ... well ... if you're going to use that one, then you may explore other carb options.

my advice is if you're new to this (as you stated) use the Nikki. you asked if they're reliable ... well ... the answer you get is going to depend on who you ask. my answer ... yes! as long as they're cared for and maintained (like any other carbie) they're uber-reliable and they WILL make power!

all of the carbies mentioned can be made to work on the street RELIABLY it's just a matter of knowing what you're doing and most of all, being patient.

claytonsmith

thanks yall... you;ve been uber helpful.... when i get teh car i'll be here bugging you with more questions i;m sure

now dont everyone go forgetting bout the dell'orto...if you can find one...better than webber....more streetable........

I also agree Nikki's are capable of making decent power on a stock port motor. A couple night ago at the 1/8 mile track around here I ran a 9.96 with a slightly modified Nikki and RB header, my buddy went 10.4 with Webbers and RB exhaust, and my other buddy went 10.5 with a Holley and exhaust. Granted, as soon as they both get them tuned alittle better, they should be faster, but till then, I can enjoy the money I saved

claytonsmith

cool cool.. unfortunately.. i;m 1/8 mile stupid... if i remember correctly.. an 8 second pass in the 8th equals about a 12 second pass in the 1/4 right?

CrazyJoe12a

Yeah, I think you multiply your time by 1.5 to get a VERY rough idea of 1/4 mi. time. I still dont know anything about drag racing either, it was only my 2nd time ever going, I prefer AutoX...
