I have a 4 port carb manifold for a 13B 4 Port (Racing Beat) but I don't want to shell out $600+ for their holley carb. I have found one much cheaper, question is will it work out of the box? What about oil injection and throttle linkages?

 

I shelled out for the entire RB kit. But my cheap *** firend who won't buy anything new and haggles every deal he makes, has roughly the same thing I do but just bought a regular 600 cfm double pumper and just tuned it. And his seems to run better than mine at this point. As far as linkage you might have to but RBs throttle cable holder if the Holley does'nt come with one and get a TII throttle cable. The cable is way too long so you'll have to route it around to accomidate. Also the actual inner cable is too long so you need to take up some of the slack. I took a nut that was the correct thickness and hacksawed a slot in it. Put it around the cable down by the pedal and cliched it shut. And lastly the pedal throw is not as long as the Holley carb butterfly throw. You'll find yourself getting only 70-80% throttle. You need to remove the pedal and bend it out(away form the floorboard), otherwise the floorboard, carpet, is now your throttle stop. Waalah, now you have a carbeurated second gen. The looks you get in parking lots is almost worth the hassle.

 

Oooh yeah. Get the cheapest Holley, Carter, etc. fuel pump. They are pre-set to 6-7 psi which is what you want for your Holley. Remove the factory fuel pump and use the return line(in the tank) as the feed. It is the one that is a bare tube that hangs down almost to the bottom of the tank. No fuel pressure reg really needed.

 

Thanks! My plans right now are to buy the 600cfm double pumper and tune it for my n/a 6port until my bridge port is complete.

One more question, what about factory ignition timing, can it be retained after fuel injection has been dumped?

 

Need a distributor.

 

WTF? call me a stupid aussie, but umm why are you taking the EFI off anything?

is aftermarket management exxy in the US?

because by the time I got a holley and manifold over here, it would only be a matter of maybe a couple hundred aussie dollars to get a good aftermrket computer.

 

I'd give anything to have a Haltech fuel injection system with a TWM manifold and throttle bodies hanging off the side of my motor, really. I talked to Hitman once about it and he quoted me about $2300.00 USD. Not including a laptop to program it. $400-600 est. Used of course. It's just cheaper to go with the RB kit. About $900. Fuel pump is around $100. Some steel braided line, a filter, done. And running. Tuning a holley isn't brain surgery. And any V8 gearhead can help, ya know there's plent of that around. Don't shot me if I'm wrong but I think you can get more HP from a N/A if it's carbed. Unless you go with my above short intake system I mentioned above. Actually I've heard the best N/A carb setup is the Webber IDA setup if you can find one. I recently heard that some company is making imitations that are just as good. I don't know the name but I'll try to find out. I don't know what kind of HP a 6 port would make with a carb but I know that my Holley is one of the things thats keeping me from the 300hp target. Either a Webber or the trick F.I. would help out greatly.
Rota your not a dumb Aussie, I think maybe finances are just a little different here. I think just about every N/A driver would jump on my F.I. concept if the price were right. It would look alot like the 787B F.I. without the runner adj.

 

hey man, alot of the EFI systems people use downunder are pretty simple things, often a electronic ignition with a weber style throttle body and manifold.

but then again, most of the aftermarket/modified scene over here uses early rotors, R100, RX-2,3 and 1st gen RX-7's. most people that use 2nd gen go for a turbo conversion straightup, and yeah, maybe the supply is cheaper for the ECU over here, alot of aussie companys do it.

so you guys also think a weber is the better setup? I am playing with the idea of a holley on my ported 12A because a weber is just too hard to find.

 

I know of a company who sells weber setups, I am at school right now, I will post the site when I get home.

So I will have to go distributed, what kind of distributer? From a first gen?

 

mazdaracing.com sells webers

 

you may be able to keep the factory computer running the ignition only, but if its capable of running the ignition it would run the fuel as well? unless you go some kind of bridge etc.

but if you cant get it running to your satisfaction with the factory timing control (might confuse the comp with all the unusual signals) probably easiest would be to install what we in OZ would call a series 2 electronic. ummm yeah its a 1st gen, the most popular is the later electronic ignition, with the modules on the actual distributor body.

hmm, havent looked at the sights selling webers, but I bet they scare me off, I mean I turned down a weber and manifiold from a friend recently for $1100 australian.

 

Actually the weber kit is slightly less than the rb kit around $830 i think.

Could I get more details about first gen ignition? I am interested

 

i originaly made a 6 port intake myself from the stock lower. made a plate for a holley and had a plate for nos. it worked fine. latter i went to a jay-tech 6port intake. i used a holley 650 DP mechanical secondaries. this was all for a 74 rx2 when i had a 6 port from a 88. i still have them (manifolds) and may be willing to part with them as i have moved onto a r100 and have a tII setup for it.

 

oh as far as oil injection. premix. i also used a dis. from a 1st gen.
i did at one point have the OMP rigged up to dump the oil in the bowls. kinda ghetto, but it worked.

 

How much rxrotary?

 

uhh, what details do you need? to my knowledge, the guys running the later engines with 1st gen ignition, just use the distributor out of a S2 or S3 (1st gen with plastic bumpers) and any electronic ignition coils, bosch are popular.

if you need anything explained in more detail, post your questions and I'll try my best.

 

I'm using a 1st gen dist with no problems. Bought two generic coils from local parts store and they work just fine. Made my own plug wires from an Accel kit. It was pretty easy just make sure you index the distributor right when you install it. We had some problems trying to start the car and think it could have been indexed a tooth or two off. The crossed wires on the ignitors didn't help either. You can see some pics by clicking the link in my sig.
