Talked to a guy last night, he has the same car I have a 97 Civic EX, but the sucker get's to 110mph on third gear, with I/H/E and an Civic HX transmision, He says the EX trany is weak and the gear ratios are too far apart and that that would hold the car a lot. I can get to around 95mph on third and I have an OBD1 chipped ECU redlining @8500rpm, and a stage 2 clutch. Any of you guys heard of this before? Also have a friend selling a transmision from a 90 Hatch Si, would that fit and be better?
any info thanks
Now I'll go and try to research this further
Google Yahoo here I go!!!!!!!!

 

the hx tranny is an economizer piece of dog ---- with the longest 3rd gear known to man. my brother has a vx htch with the same tanny and i hate it. you can do 90 in 3rd gear. it sucks. you would need about 400 hp to make that trnny work. id use the ex its way better.

 

Well my real problem is that my car used to run pretty good for being NA, best time 16.4. After I ran that time I added headers, an MSD blaster coil and cap, FPR, and the car actually felt worst. A guy told me it was the clutch, got a stage 2 Centerforce clutch, same ----, best I could do was 17.8. When to a place called Honda Car Clinic in Orlando, FL, the guy told me my problem was the stage 2 clutch, that I should have gotten a stage 3 or 4, that's just stupid. Then I got a cam gear to adjust timing, took it to another shop in orlando, the guy told me it was my ECU??, He said if I got a DOHC-Vtec Si ECU or an OBD1 ECU it would run better, Got an OBD1 ECU chipped redlining @8500, it feels better but still my best time is 16.8, much better than when my problem started, but bad comparing it before when I only had Intake, Exhaust, spark plug and wires. I read in here about a CRX with a mini-me that ran 17 something and after some timing adjustment he ran 15's. I have never fixed the timing on the car, yes I have played with the distributor moving it to advance the car and the last guy that put the cam gear on moved the distributor a little, but I have not fixed the timing with a timing light. Before I could kill any stock Integra non-Vtec. I think it might be something with the car's timing, but because this other mechanic told me that my problem was the transmision I though I could ask. I don't expect it to run 15's but at least get back around 16.4, 16.3 wich it once ran.
thanks for the info, that would explain why he gets to 100+ on third.

what fuel pressure are you running? could be loosing power if too rich.. also.. put your timing back to stock if its WAY advanced.. you loose power when its too advanced...

i have a I/H/E cam, light flywheel and a centreforce dual friction in my rex and it runs 15.6's

and yes, the Si tranny would give u better acceleration, but you'd be turning 3,000-3,500 rpm doing 60 in 5th good luck

 

Are EG & EK trannys swappable? pretty sure they are.. The EG p20/a20/s20 EX/SI tranny is the shortest geared hydro D-series cable trans...

HX/CX/DX and all those other trannys are ----, especially the CX. The CX tranny has the same gear ratios as the L3 HF tranny. 2nd Gear goes to 92mph lol

well i dunno about u killing non vtec integra dude, cause my STOCK 91 GS ran a 15.9. anyway, i think ur way to rich, that is def a possibility. i had a friend in the exact situation as you. he had a million bolt uo upgrades, all top of the tine ----, and his car was slower than ----. i didnt get it. he finally took it to a shop to get it tuned, he went from a 17.1 to a 15.7. all with just tuning. go somewhere that knows WTF they are talking about. dont try to make them tell u that u need an OBD1 ecu, cause u dont. sure OBD1 is easier, but ive been OBD2 cars in the 12s on the stock computer and piggyback fuel/spark computers. take it somewher to have it tuned man, even if you have to travel a couple hours to do it. oh and i didnt meantion, the guy i was talkin about had the exact same car as you and kept his OBD2 computer. just trying to help dude. good luck man, with all that work u should be in the 15s EASY

before we get all out of control with stuff, let me ask you something. did you install all the parts yourself? and if you did...did you tune it? tuning is a BIG key to being fast. you cant really just "bolt on" power. you have to unlock it from within. I totally agree with everyone else on the fpr running too high of a psi. And all that the dohc ecu is gonna do for you is bump up fuel and timing maps. and also.....who said the higher your RPM's go..the faster you go. just because you have a chip in your ecu that lets you rev to 8000+ doesnt mean you do it. especially a sohc. they dont make much power after 7200 or so. i had a 8200 limit on mine but i had the right head work(valves,seals,retainers,springs) to support the high revs....and plus i had 44 mikuni side drafts on it. but it was a real programable chip w/ warrante from dinan. not some cheap *** ones that everyone has now that they do for dirt cheap. some arent, but alot are. some people just run a circut to short or overide the main governor. thats it. and just add a cool catch to it like "spoon" or "mugen" programs for 100. but my point is that your motor cant handle the high rpms and WILL sooner or later, go out on you. your pistons will bottle neck if you ---- up one day. and the HX tranny?? you must be crazy. how could a super long geared tranny compete with the shorter ratios of the ex/si's. well they arent super closed ratios like hybrid ones but they are way better then the hx/vx/cx/hf ones. let me show you
si/ex
1st-----3.250
2nd-----1.900
3rd-----1.250
4th-----0.909
5th-----0.750 for Si HB and Del sol Si
or------0.702 for 2 dr or 4 dr sedan
or------0.771 for 88-91 si
Final Drive---4.250

hx
1st-----3.250
2nd-----1.761
3rd-----1.066
4th-----0.853
5th-----0.702
Final Drive---3.250

look at these numbers.....how can you want this. the only reason hes at 110 on 3rd is ....cause thats all he has. 4th and 5th will slow his *** back down cause it'll drop his rpms way under 3000. trust me....its not good.
And the clutch thing. why get a power grip off like 300+hp when your car barely hits 100 hp. you'll just be blowing trannies and burning tires. just cause you can do crazy burnouts going into 3rd doesnt mean you are fast. your just damaging your motor/trans more then you are helping it speed up. the heavier clutch wont solve anything except give you more muscles on the left leg.
my 2 cents would be.....get tuned by a "reputable" shop that deals with dynos and unlock the power that you have already that arent putting out yet. dont add more mods you dont know. good luck

 

That's what I told the supposed Honda Expert, Stage 3 or 4 clutch with my superpowerful 100 some hp, come on, never havegone back there. The last guy that installed my cam gear and "tuned" the car, bumped up the fuel pressure to like 65psi, as what my fuel pressure gauge marks, when stock is what 32psi. My Air/Fuel gauge always marks rich when accelarating, never stoich and never lean, What should it be I've had different people tell me different things.
Also I have done somethings, and some others I have taken the car to different shops, never have dyno tuned it, which is waht I should do, so I'll make an appointment for next week somewhere in Orlando, I think there's only like 3 places that could do it around here. And the Integra issue, I raced 2 of my friends, one had a 1991 ls and one was a 1996 GS both with intake/exhaust, and messed them up, that was before all this started, by like 2 cars, I would pull out quick 1st and 2nd, then in third they would catch up but never pass me up to like 85 90 mph about 1/4 mile.
Thanks for all the info, I will try to lower the pressure and see how it feels, and definately take it to a good dyno equiped tunning shop.

Ok now you guys sound like the pro's but the hx tranny doesn't lose power till about 121mph(in 4th) where the fuel cuts off. I don't know why you think its done in third when its not done till 4th and who's knows with more power and no speed govener 5th could even have some benifit. I have one with I/H/strait pipe, underdrive pulley, excedy clutch, lightened fly wheel and it breaks loose when I shift into 3rd, I will be adding boost and goin to retain this tranny for top speed reasons, till it disinigrates at least.
but as you guys are talking about running the 1320 I wouldn't think this tranny would be worth ---- in the quarter mile but i kinda like the long gears when i auto/rally X.
just my $0.02
