Hello, this is my first post on this forum, I've mostly been looking and reading over threads here for a few months now.
Here is my 1991 AE92, it is lowered with weapon R coilovers( i know, not that great), it has a header, 2.25" exhaust, and a short ram intake.
Anyway, the real reason I'm posting here is because my poor corolla is needing a boost in HP. Now I know most people are gonna say SWAAAAAP, but thats not what I want. I plan to keep the 4AFE that I have and either turbo it or spray some N2O.
My goal is to be able to get low 14s/high 13s in the 1/4 mile with slicks.
Is it possible with nitrous?
If I were to turbo, are the stainless steel manifolds they have on ebay right now any good?
How much Hp would I need to take my AE92 into this time bracket?
So you think a turbo corolla coupe would need 400+ WHP to make it to the 14s? A 185 whp civic coupe will do 14s, with nitrous they would break into the 13s on slicks. I guess we'll just have to see what i can make the poor corolla can do.
So it takes a toyota double the hp to run the same time?
Does my AE92 weigh like 7000lbs or what? hahaha
The civic in that link weighs 2443lbs factory
Does anyone have an idea what the AE92 weighs? its snowing here now so I can't bring it out but as soon as its stops I'm going to put it on a scale so I can see myself about how much hp it will take.

1100 kg is about the same as the civic in that link, give or take a few. I know there will be traction problems, I had hoped to try to run a 20x10x13 slick on the front to help with that though.
in all honest if you want a drag car the corolla isn't the best option. These cars are meant to corner. Having things like light weight, independent suspension, close gear ratio... If you rather drag then go get something that is better at it. In the end you'll be happier since it will cost you a lot less to modify something like a mustang.
Also with a 2.25" exhaust and headers did you notice a drop in power? I know a couple guys who did the same with their ae92's and found the cars felt less powerful.
I think 250 - 300 hp will definetly get you into the bracket you are looking for. But it won't be cheap to pull that out of a 4afe. You are looking at a lot of money and time into that engine.

I'm not soley into drag racing so a mustang would be a horrible idea in my opinion. A turbo 4afe "should" make around 200whp with boost, maybe a few less. When the 4afe goes its on to a 7agte. Right now the 4afe is what I have and its what I'm going to use for me turbo "education" Hondas are everything you have described also but there are hondas that run 9 second 1/4 mile times at 150+ mph, this is no where near my goal but just because a car is fwd based and not meant to be used for "racing" doesn't mean it couldn't be a fairly capable and even pretty surprising little car.
Also, on a 4 cyl car headers should not be plural as there is only one "header"
No I didn't notice a drop in power at all, it actually pulled stronger from my testing, not much, but 2-3 mph in the 1/4 mile. The SRI I added didn't seem to help much though, I kept it for the extra sound, it seems to make my exhaust deeper.
Just out of curiosity, every forum I've been to is telling me I can't do much with the 4AFE, How many people who have replied here actually have any sort of performance or F/I personal experience on this motor? I'm not saying people don't know but a turbo hasn't been done big bunches of times and every thread I do see about one people have good results, even after the 334390 people who say it won't work.
Anyway, thanks all for your opinions, I'll let you know guys know when I reach 225HP at the wheels which is 167 KW.
The Honda you linked has a swapped B18. Notice he didn't boost the D15 that comes with those(I think they're D15s). Second he has a GSR tranny, not the stock tranny that came with his Civic. I'm not surprised that he ran that well, I have friends with K20s running 14.1, 14.2 on street tires with basic I/H/E.
The reason alot of people are telling you if you want a real fast car to not boost the 4AFE is because the 4AFE doesn't have much parts availability. Look at JMAZ. I'm pretty sure just about everything on his setup is custom. It's too much of a hassle to go through if you're wanning to run 13s. There's a video on youtube of an AE92 from Australia running 13s on 29PSI with street tires. He's pushing around 350KW+.
1100 kg is about the same as the civic in that link, give or take a few. I know there will be traction problems, I had hoped to try to run a 20x10x13 slick on the front to help with that though.
in fact, its lighter than its counterpart
a good example would be the 4door AE92 versus, the 4 door civic, the AE92 is lighter (and yes the sedan is lighter than the coupe in this case for the corolla, 1024 for the sedan)
in fact, only the 9th gen corolla is heavier than its honda counterpart
teh coupe weight something like 2425lbs
the sedan weight something like : 2252 lbs

If you want to build the 4afe your going to have to be prepared to spend more money to get the power levels you want, this is why most people just swap a 4agze. There is little hope of 225whp on a stock 4afe even one with a good aftermarket computer with a good tune. It just won't handle the boost (for very long anyways). I like drag racing myself and am building my corolla more for this purpose.
My stock 4agze with only the small hks pulley in a 1988 corolla gts with stock gts exhaust with cat., stock gts clutch, stock c52, bad alignment, worn winter tires and stock motor mounts ran 15.09 @ 91 mph. It should be capable of mid to low 14s with the above mentioned items fixed. The motor is around 160whp from other cars with similar mods, but I have never dynoed mine yet. Your going to need around 190whp to make it into the 13s with a good launch and knowing the actual powerband of your motor so you know when to shift to get the most out of it. Oh and a c56 wouldn't hurt either.
Know what you want to build the car for then reasearch.
Almost forgot your going to need a e51 or e58 to run with slicks. Any of the c series transmissions have small, unequal length axles that will most likely break if you were to launch it at say 5500 rpm with slicks. Your going to have to let it slip some off the line or what I did was just take a easy launch then get right on it. Slicks are not needed.
