Hi im new here, I have a 72 Datsun 510 and im puttin an 87 6-port 13B. I am planning on putting a carberator on it instead of going with FI. Should I stick with FI or go with the carb? Also, do you know anyone that sells a side draft intake that fits the 6-port pattern? Thanks.

I have a 6-port sidedraft setup.Works pretty good but depending on the use of the car and if you have the time to wire it up you might want to look into a stock 86 EFI system.

www.racingbeat.com and www.mazdatrix.com for all that manifold stuff and other parts



why go carb when u can go EFI, price is about the same i would assume,

and the EFI gives much more flexibility, if it will be a stock 13b just put the stock 13b efi on it



if u want to play aroudn go with a standlone.



carb is nice and easy but its not as flexible and part throttle will most likely eat more fuel then tuned efi

Something else to consider is utilizing the stock 2nd gen intake, eliminate the AFM and get a Microtech EMS to control the engine. I'm going to end up with something similiar to this in my FP car. The longer runners and functional 5th/6th port will help with the lack of torque but you still retain some good top end now that the AFM is gone.

I had a similar setup on my RX-2 once upon a time, had a 6 port 13B with a port matched intake manifold and 48IDA weber, it pulled quite well, but I'd chose EFI over carb anyday if you can afford it and like lots of wires https://www.nopistons.com/forums/pub...IR#>/smile.png

Thanks for all the info guys. I still dunno what i'm gonna do next, wires freak me out and i'm not the best in the world at hooking all of them up
