Street n Strip - Just curious about 1/4 times?

Im just curious what would the quarter mile time be for a 93 civic ex AUTO with the following mods. I know it's kinda hard to tell, but in a approximate ball park.

Apex turbo with intercooler, 6.5 PSI
VAFC, DSM 450CC injectors, Walbro fuel pump, and AEM fuel rail
68mm TB, Skunk2 IM, and Tsudo cat back with a decatpipe.

I would have to guess low 15s to high 14s

yeah. and those injectors are WAY overkill. try to get some 270s or 310s. thats plenty for low boost. much bigger and it will just run really rich.

And your MPG will go down the tubes










I dont really know what tubes I speak of but trust me, it will go down the tubes

Ok. As far as the injectors go, its like every where I look when it comes to turboed D series, every one has 440's or 450's. How would I be sure to get enough fuel through the 270's? Would they be able to put enough fuel at 8 PSI?

yeah. in all honesty, the stockers would be fine for about 8psi, but you would be on the limit. the 270s would be plenty. i did all the math a long time ago on my gsr for like 6-7 psi, and i decided that 270-280 would be more than enough. so on a sohc, youll be golden with 270-310s even at 8 psi. esp with race fuel.

when you say race fuel you mean 91 right?

no. i mean 96 minimum. anything 93 or under is considered "pump gas" but even with premium pump gas, 310s will be fine at 8 psi. and i would be pretty confident with 270s.

I'd guess low 15's... it's really hard to guess-timate a turbo setup, too many variables.

yea i know

Hey fast93, where do you live that you can only get 91?

Midland Michigan, and some imes I think 93 is available, but I never seem to see it as often as 91.

yeah michigan sucks royal donkey balls. i dont think ive seen over 91 in my life here

What's keeping you from a track and finding out?

long distance. oh, I would love to go to a track, but the closest one is like an hour drive or some thin like that, I don't even exactly know where it's at.

i know where the nearest one is and how to get to it and everything...but im not putting my car on the track till i get an intake, exhaust, and high flow cat.

man you from!!

crap, I meant where are you from in Michigan?

Right on dude, I hear ya. Beat situation. I suggest you find a dead strip of road somewhere with some friends and make an unofficial run.

G-Tech. its better than nothing.

i live in michigan....where are you from?

Midland Michigan, I though that Nail was also from Michigan wasn't he?

I'm from Grand Rapids, and Nail I3unny is from Portage i believe

Mid 15's at best....Honda auto trannies suck balls and the tq convertor's are crap

o I think I can do better that mid 15's

You think so lol

I have been doing this stuff for a long time and I myself am boosted. Mid 15's is being nice.

93 Civic EX has 128hp at the crank stock, with a 5 speed that is around 110 hp to the wheels given the average 15% drive terrain loss for a manual transmission. Automatics average around a 30% loss in the drive terrain so that will put you in the 90 to 95whp mark. Now depending on what size turbo you have you will get anywhere from 5 to 8hp gain per lb of boost

6.5 * 10(I'll give you 10hp per lb of boost to be nice) = 65whp

95whp + 65whp = 160whp or so

Ok so your in the range of a stock GSR now with whp but with around 20 more ft lbs of tq

1996 Acura Integra GS-R 7.1 15.5 <---- that is from the sticky at the top of the page and no doubt a manual transmission car, see you will have better tq but your auto tranny will suck most of that right out with it's crappy tq converter,slow shifts, and all around crappy gearing

On top of that a automatic car weights more than a manual car.

I am not trying to down you or your setup but physics are just that physics and on top of that I have watched this stuff with my own eyes. Get yourself a higher stall tq converter and a shift kit of some kind if you plan on running the automatic with good results, otherwise just go ahead and swap to a 92-00 ex manual tranny

Dont forget you are comparing a heavy ass teg to a light civic.

Sacs car with a bone stock gsr in it hit 14s

and automatics do NOT lose 30% to the wheels...a RWD automatic only loses 28or so % to the wheels

That is just a standard that is used across the industry.

That light weight is totally thrown off by not being able to shift at the right points and having crappy 60 foot times which will happen with a automatic civic. I am running around 8 psi from a t25 and getting 2.2 to 2.4 60's and that is with launching at 5000rpm on street tires. Please tell me how you are going to do this with a stock automatic from a civic.

Plus the average automatic transmission takes .09 to .1 seconds to change gears while a good driver with a 5 speed will shave that to .02.

So take .09 * 3 which is the amount of times it should shift in the 1320 and that pulls another .3 or so off the 1/4 mile times

You will not run high 14 second 1/4 miles with a 2.6+ 60 foot time and shifting at 6300rpm with a civic even if it does have 160whp

How much drivetrain loss do you see with AWD?

well most STI's and EVO's dyno at around 240whp stock

damn, slow down dude. First of all, you cant compare integra to a lighter civic as stated above. Second, my civic does not shift at 6300 RPM even if it is in D, but usually I shift it manually if I want it to move, and it is a little bit faster. Thirdly, a stock 93 ex coupe auto does about 16.7 in a quarter, you're telling me after running at 8 PSI (which is what Im planning) I will only be able to lose like 1 second off my time? Not to mention I have a 68mm TB, Skunk2 IM, and a free flowing exhuast. Im almost positive with my current mods, and my turbo at 8PSI I can do a 14.7-14.8. By the way, a stock 93 ex has a 125 HP and not 128.

whoa whoa whoa guys, heres the thing, we need fast93civic to take it to the track and get vid footage and end this battle. I have a question for fast93civic, why don't you do a conversion over to a manual and change you name to faster93civic?

I am not trying to be an ass or down your setup at all man so dont take it that way I just know how much honda automatic transmissions suck and I dont know where you got that 16.7 time from and that is right around what a 92-95 civic ex 5 speed will run but I 100% promise you that a stock 92-95 automatic civic will not get near that time. Gearing,gearing,gearing man it's all in the gearing and the lack of control you have over your automatic transmission.

Just do me a favor and take it to the track before you boost it and see what it will run then come here and post a time slip. Your 60 foot times will be complete crap because you will have to launch at 3000 or so rpm. Also if you plan to like leave it out of gear and throwing into drive or first when the lights drop while your reving to 4 or 5000rpm do cause you will rip your tranny out with in 4 runs.

I totally agree... low 15's at BEST, especially since you have an auto tranny. That's just how it is. Also, a full second on the 1320 is alot, especially whenyoustart getting into the lower times. People spend thousands of dollars to drop a fraction of a second.

where can these be found?

This is what a 5 speed will do in a quarter.

1992 Honda Civic EX Sedan 9.4 17.0
1992 Honda Civic Si 8.5 16.4
1992 Honda Civic Si Hatchback 8.4 16.5
1993 Honda Civic Coupe EX 8.4 16.5
1993 Honda Civic del Sol Si 8.8 16.8

The reason I don't do a tranny swap is because it costs money. I will try to get the Gtech depending on how much it is, if not I'll make an unofficial run with a few buddies. Im not gonna argue wether Im gonna hit 14's or not. I'll just post once I get a chance.

I'll get a gtech, its only like $30 on ebay. I'll post my current time in about a week or so.

Ok, I dont want you to take it as me downing your setup or your car bro just giving a educated guess as to what it may run. If you need any help with your setup pm me cause I am a avid d series fan that knows my fair share about turbo setup's and so on.

One thing I do want to know is what size is the turbo you are running?

I dont know if they even make them to tell the truth, I am just going on my exp. with GM RWD tranny's.

BTW fast93civic if you need a higher stall tq converter lmk cause I can put you in contact with a guy that fabs them for fwd import applications

I just bought the turbo a few days ago, and it's still being shipped. All I know is its an Apex turbo kit, made for a 92-95 civic. I think its like a 16g. Slightly smaller than a T3

what turbo do u guys think is better? The 16G or the 19T......

what ar spec are we talking here?

DUH...............................16G

there are many different sizes of both

i am pretty sure there are no shift kits for civics. they have different auto trannys than most cars do. its more of a manual tranny made to shift automatically, instead of a whole different setup. at least thats how my buddy explained it to me when he was in a drivetrain class. but ive heard some stories of removing the solenoids and putting stiffer springs in there and they shift HARD. but it destroys trannies in short order if you go too far.

Ok, got the turbo in the mail today, and it's a IHI AX53B60-P18. Read some stuff online about them, and from what I hear, they're ok. Any opinions?

big16.........................DUH

yeah...forty's right. portage
