Do I have enough carb for my motor?

The AFB is a little small for that combo.
However, the AFB is MUCH easier for me to tune. I can have the jests and rods swapped out in just a few minutes and never spill any fuel.

I'll take the better street manners and economy of the AFB and give up the .000000001 second at the track you get with the Holley.

I guess I better get a metering rod and jet kit for the AFB. I have a race in a few months

---

Check what size rods/jets your AFB has & order an eddy strip kit w sizes a slight bit richer than current. Can lighten the counterweight so the secs will come in sooner and can remove the boosters and narrow the horizontle leg part and can narrow the throttle shafts/screws if you want to experiment w what you have & yes the AFB's (& clones) have better street manners but I would borrow the Holley again when the time comes to kick his tail (& take his money)

You really need to find an LM1 or some O2 sensor to put in there to check it out. Just richening it up may hurt performance. The 625 tuned correctly ought to be plenty for that combo. But you're asking a lot against a turbo, i've seen some of those guys at Tulsa and it will be tough no matter what you breath through.

The 625 is on the small side, & the 750dp is too much for a mild 360, a 650dp will work a whole lot better for your set-up, i took a basic stock (high mileaged) 360 with just bolt-ons in my 71 dart to 12.5 consistantly, it was so mild it would only pull to 5100 RPMs, now this was a magnum engine, if this honda is basically stock (with a turbo) you "should" take em, i won't say much more other then be awhare of these cars, they can go in the 11s quit easy & you won't see it coming till mid track .

Might have to hide a bottle of NOS

That was my next suggestion , never hurts.

300 HP at the wheels in a civic is going to be hard to beat if he hooks up.

One of those weigh...2500 lbs or so & figure 2700 "race" weight unless he gutted it.

So that is a LOW 12 sec ride if he has all his ducks in a row.

---

Those civics are lighter then 2500 lbs. i'll garuantee you, they are light, even if its not 300 to the wheels, if its pushing 300 FWHP it'll run hard, i ran 12.5s with 280-290 RWHP at 3200 lbs., that civic is a good 800-900+ lbs. lighter then my 71 dart, so your looking at an 11 second car if he can leave good on the boost & hook up, basically a clean run.

Here at our local track there were 2 civics running 1 night, both local guys, I saw 1 run on 3 weekends, the 1 was a plain jane no thrills, his best time was 11.5 @ 117 & none were clean runs, the other was a little "monster", it was in a sence "no thrills" looking, i know the guy personally, he has a local car lot, Its a single turbo, He could never get off a clean run, he mowed down just about everything at the track 1 night LOL, car only made 10.4s best ET, but the MPH was 138-142 , this car was tagged too.

Nope.... 750DP w/ 28 squirtters, 72-78's and It'll get it done.

---

I disagree, not for any mild 360, its just too much carb

Have a friend that had a 13.0 sec. 340 E Body. Best et and mph was with a 750 DP on a LD340 intake.

That said, there is probably something else amiss for the AFB to be a full second slower than the 750 IMO.

My mild 340 swinger had one of those Carter 625 comp carbs on it. ran fine. I had a 750HP on the shelf. Drop it on w/ 28's and light jetting and it ran killer. went form 14.20 to 13.80 and had zero effect on mpg or drivability. Holley 750's are VERY easy to tune and work on almosty every application. He has more cubes more cam and btter heads. A 750D tuned will work great. Now a 70 will too but you can't swing a dead cat at a swap met and not hit a 750 for sale.

I doubt it. We shall see. My prediction is I beat him by half a second. I have doubts just putting a turbo on a honda civic makes a low 12s car. He's got alot more things that have to go right than I do. My car runs good and is consistant. He's still working the bugs out of his and he has to drive a stick shift and he better get it right out of the hole and not miss a shift!

Smaller carbs have better throttle response. Most daily driving is done with part throttle. So yeah they would be better for that.

13.80s is all you got out of that Swinger, Any holley DPer is easy to tune, that has nothing to do with it, If your happy running high 13s with your 750dp in your Swinger thats cool, i'll take running 12.5s with a 650dp on a mild 360 in my Swinger .

If its a stock engine internally enough boost to make any power will turn it into a grenade.

Not neccessarily. They don't need much to make them move, good clutch set-up & axles/sticky tires/exhaust ect. & they can run 12s all day on a small boost. Heres a link, notice how fast the Neon runs with stock internals, & the weight too, they weigh about like a civic.

NOW, look at the HP & weight of this civic, its not insane by any means, look at the ET & MPH, not trying to burst bubbles here, just proving a point on reality, i've aslso includeing a Neon, yeah & thats a Mopar.

Yeah but thats an SRT-4 engine, which came with a turbo. I dont know what a civic has for a compression ratio but i'm sure its at least 9.5:1. We'll say that maybe it will take 7 lbs of boost safely, that might make 275 to the crank as a best cast scenario, depending on what engine they started with, so we're talking more like 225 to the wheels, not 300.

Civics are not only the butt end of our jokes, they are the butt end of jokes from the tuner crowd too, and for good reason. You can not make them fast and hold up without spending insane amounts of money. I know guys who spent 8K on an engine to run 13.50s in a 2600 lb car. Can you make them fast? Yes. But you will spend way more than you would to make a better car as fast.

The guys dropping 8K on an engine to run 13.50s could easily have bought an LT1 or LS1 GM product and done a gear swap and run faster, with more potential to improve. They also could have bought a car that came with a turbo, like a WRX, and just done bolt ons and cranked up the boost. I know the tuner cars are very capable from working on them. You can make them VERY fast. Hondas are not tuner cars though, they are just cars. With the cost involved with making them run and hold up its like guys are removing the valve cover and literally pouring money into the engines. And lets not forget, to make them really run you have to get an engine all built up to take the boost, then spend a few thousand to turbo it.

Back on topic do whatever makes it fastest. If you can't tune the Carter to come close to the times the Holley makes it run then the answer is no you don't.

Who are your kidden, they don't sink any more into there cars then we do, but obviously you must be an exspert on imports ..
