AE86 4AC & Nitrous Oxide....
Hey everyone,
On the 6th of february I purchased an AR86 (sr5), and am beginning the conversion to GT-S. Currently its in body and paint getting all the body and paint work done to it. Once i get it back, I plan on putting together the suspension. Problem is, it doesnt have a 4AG, or a 4AGZE, but the lame old 4-AC. Pretty pimp carburated engine if you ask me... The car hasnt been tuned up in ages, and will go through complete tune up, and gasket installation when i get it back. I need to recover as much of the original 80 horsepower as possible. Im also installed a compelte 2 1/4 inch straight exhaust (no cat) to a HKS hi power muffler. That should boost it 20hp. If i had the 2K for an engine swap, id already have it. I however do not have the money right now, and am looking at that as a mid summer, end of summer project. I just want it to look nice, and have a good suspension set up, and be able to drift. Problem is, after im done with weight reduction, I will have a mediocre power to weight ratio. It needs to be better for drifting, if i dont plan on burning up my ebrake and my clutch. Im considering installing a dry nitrous oxide kit on the car. Ive been researching this and have been talking to people for the past two weeks. I think a good 50 shot would make the car quicker, (keep up with my friends 240's), and ensure a driftable car until its time for the swap. Ive learned that similar engines have handled up to 100hp shot, and have absolutly no problem in doing so. I understand the risks involved in this, and I like to look at it this way -- once i blow it... ohhh darn.. time for a 4agze swap... Anyway, let me know what you guys think about the nitrous idea. Include experience, rumors you may have heard, or anything that will help me out with this. Also any other upgrades that will help me get the car up to around 160 horses or so. I do think it would be cool to be the only person to have the 4 AC engine that can drift, and take out some hondas every now and then. Ill be posting pictures soon. I have a ton of them but havent listed them anywhere quite yet. Let me know what you guys think, and keep in mind is a 4AC, there is hardly anything for it.. thanks guys |

freakin a...
in all honesty I could probably buy the 4ag.. right this second, and pay preperformance to put it in for me. however! i want to experiment a little. but in the right way. not too many people have tried nitrous for drifting, and when your doing it on weekends with friends then it cant be that bad of an idea. i know nitrous, if set up properly, with regulators and such, could be extremely feasbile for what i want to use it for. Heres a run down Im 17. I go to high school and summer is coming up. One of my friends has a 240 and the rest a following close behind.. Im the only one with an AE86, and a slow one at that.. The car will be drifted mostly on weekends and such.. Its a 2 barrel carb by the way... |

then try it and learn how to drive ur car first before u even think about drifting  ...and maybe u might have the money by then to get ur 4ag u wanted..i even would try to do it before u make rash decisions for parts u might not even need and waist your money on...

lol. yea. well. how long did it take you to get to know your car? or are you still learning it? the car needs more power and nitrous is a feasible way. stick to the original thread questions too. i've went through all the threads with nitrous written in them so i know this isnt a repeat. and brad i found a tight 240 for sale that tim might like. it looks like that one you guys were looking at and the dude sold it. the license plate was 385-SKD. wa plates. comprare them to that one pic and ill ask you tonight if its the same one. ill show you the pics i took with my phone too. id look now but im on my phone in a clark class.

buy the damn 4age, sh!t cost like 400 bucks man, nitrous has already been tried by D1 driver too, so you wont be the first. experimenting is good but that just seems like a bad idea, but if you do go ahead and do it then post some vids of it on here

dont worry, there will be videos and everything. i dont think its a bad idea. people have used it before. my friends critisize the idea because they think its for drag... one of them doesnt understand what it is, and he drives a 240 with plenty of horses, the other, complete idiot, has a 84 honda thats falling apart... ill admit though, he has a better sounding exhaust then mine at the present time... he has exhaust leaks.. anyways more input ont he nitrous, 145 views and only 3 inputs... just post your experience with it, little or none.. |

everything, about 6 hours worth, has pointed me in the direction that anything up to 100 shot, an imported 4 cyl. engine will be able to handle no problem. thats why im not worried about it blowing up, just if it did, id have to replace it. plus it would be fun to kind of review the affects of nitrous on a drift car. if D1 guys have used it, but not now, mabye theres a reason... however they are full time drift cars, where mine will be used as a daily driver... |

someone is selling the 4AG in the buy/sell section for $400
I have done many nitrous installs for drift cars and drag cars. I would not run a dry system on a carbed motor, (or any motor). your motor will burn way to hot, and you will end up loosing a piston or valve before you know it. if you are dead set on nitrous, run a wet system. here are some things you probably want to do for the nitrous: 1.) compression check, this is the sate of the motor, make sure the numbers are where they are suppose to be, and that they are relatively even across the board. if the numbers are low, or uneven, your gona burn up your motor, DONT DO IT! 2.) do a full tune up, use colder spark plugs, cap, rotor, wires, change all fluids, coil, ect. 3.) check the carb, make sure its getting the mixture right, be a good idea to use a wide band to make sure ratios are where they should be, and use that even on the juice. 4.) *Censored**Censored**Censored**Censored**Censored* *Censored* the timing, check the timing table from HOLLEY to know how far to go based on your shot I would not recoment spraying a motor that is that old with out a rebuild, but if you must, be very care full and watch the mixture on a real wide band. by the way, your gona need an LSD before you can realy drift that car |

yea, thats a lot of help. when i get the car back the first thing im doing a compression check. that will really be the ultimate factor telling me what to do. if the compression checks out im doing a complete change on wires plugs car roter pumps alternater. pretty much everything just under replacing the engine. that way i can gain as much of the original horsepower as possible. because eighty is nothing. but none of that will happen if the compression checks out. im going to in look at that engine for sale. thanks man thats a ton of help. more input guys.

yea whats the number i could use it. there was one on here for four three fifty that is pretty complete. that might be just as good of a deal. let me know the number and check out that 4ag thread under buy and sale. let me know. any one else have anything else on the nitrous issue?

me personally on the whole NOS factor...
if it's used during mid-drift i'm against it, has bad news written all over it.. Actually with how old that motor is i would think the first shot would have the piston fried.... Now in the straights hey sure why not... But if you think about it cost wise a wet shot kit and install vs. a 4age and install they're about the same if I were you...which I'm not...I would go for the swap and then in the future think about supercharging or turbo  the longer lasting boost

yea. that makes a lot of sense. well Damn. maybe ill just do a major tune up and add the nitrous for the straights. hopefully i wont get pulled over for not having a cat. the muffler shop said its a 25k fine. he also said the only way they find out is through DEQ. hopefully that and LSD and a complete tune up with weight reduction will give me the drift horsepower. i guess i would like the nitrous to give me some power for the straights. hachis are slow. and i own one. man. decisions

after i reread the comment about the cost for install verse the cost of nitrous is not even close. nitrous is three hundred and i install. 4agze is 500 to a grand plus 1000 for install.. ill elaborate when i get home. im in a meeting right now lol

First off a 2 1/4 exhaust WILL NOT net you a 20hp gain. Plus a 2 inch exhaust is ideal for a 1.6-2.0 NA motor anyways.
Second 4AG's can be had at most every motor importer for aroun $350-500. I bought my hi-comp with 60,000miles and taken from an automatic transmissin (less likely to have been abused) for $380 out the door. Slap some carbs on the *Censored**Censored**Censored**Censored**Censored* if you don't wanna deal with the whole ECU wiring mess. |

2 1/4" straight pipe will not give you 20hp! I gaurantee you that it won't you'll actually be losing a huge power band if you do that, especially given that you are running a 4AC. The carb on the 4AC is very tempermental to back pressure changes, especially if it's 2 1/4.
Secondly, I would not recommend any means of forced induction with that 50 shot. Well, of course, if you want to blow that motor up, by all means do it and get a video clip while you're at it. I suspect that you MIGHT have a chance if you find a heavy duty head gasket for the 4AC if you are going to plan on building power from forced induction. You should post in club4ag.com about this particular project, I'm sure they'll give you more quantitative evidence to disprove your theory about the 20hp gain simply by installing a straight pipe.  BTW: If you're in Southern Cali, I know where to get a 4age (just the block). It's at K.Watanabe's for 350, I think 25 bucks for core charge. I pretty sure they still have a 4AGZE full clip as well. I remember them asking for 750 or so. Last edited by general ganja; 03-04-2005 at 12:17 AM. |

Hey interesting concept... we're actually modding a 4AC engine on a project rust heap AE86 as well. I picked up a sprinter as a spare for my CA18DET circuit levin, and instead of just letting it be used for scrap, we decided to do an oldschool mod on it.
So far we've taken off the standard carby and changed it over to a SU carburetor. We're in the process of fabricating a pressure box to house the carby in. Why? Because we're turboing the carby a single turbo off a Skyline R32 GTR (theoretically this is a 1.3L turbo, and should spool nicely on a 1.6L) and an intercooler off a Mitsubishi Starion, into a age old tested n proven blow through carby system. Only problem is that the pressure of the induced air will push the fuel that's in the carby back in, rather than siphon it out, hence the pressure box to equalise the pressure in the carby and outside. Once we get a manifold to feed the turbo from the 4AC and bend some mild steel pipes for the intercooler and into the pressure box, we should be ready to rock.To decompress the engine we used a 2mm headgasket, which dosen't really make a large difference, but anything helps. The idea is to do the whole thing cheap without touching the engine's internals. At one stage we were thinking of putting nitrous in there as well for lower RPM, but that involves strengthening the engine. Seeing as the engine only costs AUD$100 at the wreckers, the engine is expendable. So if it blows, throw it out and get another in and whack the whole system on it. Would be awesome for drift, which I wanna try out. Last edited by funkymonkey; 03-04-2005 at 12:54 AM. |

think I should also mention that a guy that's putting a 4AGE into his AE86 has agreed to give me his 4AC for free... sweet... another one to blow up in the name of forced induction

with that exhaust system you would probably get about 8hp. and it would not surprise me if you lost a little on the low end.
if you really want to drift, dont mess with the motor (aside from the tune up), get an lsd, upgrade the suspension, then just work on your skills |
