yeah just port it, put some series 5 rotors in, do a few oil mods, make an intake manifold and exhaust system to make power where you want, play with some timing and you'll be fine... if you have the shop to do all this than what is the question?

I do. Its a 48DCOE from a Formula Mazda. Its a great carb but I still much perfer the standalone fuel computer I had previously. I switched to the carb to break in a new engine. The porting was different and I didn't want to deal with remapping a virgin engine to safely break it in. Now that its broke in I'm switching back to the stand alone using the factory intake and possibly some TWM 55mm throttle bodies in place of the 48DCOE.



kahren is my hero! He has proven you can make real good power with the factory intake and street porting. Its all in the tuning which the standalone makes possible. You just can't tune a carb as easily as you can adjust the mapping while the engine is running.



Standalone's rule!



How's that for a short story long?

I have a carbed 12A freshly rebuilt by me. Biggest piece of crap I have ever seen. Carbs are teh gayness.



I decided today I was going to EFI it. even after my 10hrs of labor fabricating a CAI for it. After porting the intakes after all kinds of other crap.



Carbs are old technology and flat out sux.

So cause YOU cant tune it, its "teh gayness"?



Good point..



Then a carb setup is perfect for you. Im a newb with carbs, and mine is set up well. Someone with experience and real knowledge should have no problems making more power over stock.

ive run a couple of carb setups, and a couple of standalones, and they both can be a pain, and they both can run great, i like the kind of work a standalone needs better i think.

I'm doing an NA setup on my FC and I just put in the s4 4.10 LSD in and I got the 12a tranny sitting in my garage now, just waiting on buying my aluminum flywheel/exhaust.



I have an SAFCII but I haven't installed it yet



with some weight reduction my NA FC is gunna be a quick bastard.



oh yeah and its a streetport

I love how you have the skillz to speculate I can't tune when I have the work to put your skillz in a hole and forgotten.

RONIN FC

You and your "skillz" have put at least one engine "in a hole and forgotten".



This frustrated statement, to me says you couldnt get it tuned. Are you saying otherwise?



If someone cant get their EMS tuned, should that conclude that it is a "big piece of crap"? Or their skillz as a tuner isnt what they think it is.



Take from that what you will...

Nice :-/



I just finished retuning it today running perfect once again. It is the fact of the constant tuning as carbs change by elevation barometric pressure humidity and temp. They are never optimally tuned everywhere every day. I thought you knew this. EFI is not the case.



Your statement of producing more power or = then EFI is easily defeated. The power is not coming from the fuel that’s the least amount gained. As well EFI would be more precise on the mixture when tuned. But from the ignition map that is not tuned on carb setups.



The dude already has an EFI equipped motor and to run stand alone ignition modules on a carb could be dangerous but why when a EFI EMS could just be slapped on producing more efficient power all the time everywhere.

iceblue

There is a simple fact of he will NOT produce more power with a carb then the stock EFI setup and an SAFC on stock fuel pulse. He will actually produce less without effective porting.
