I,m thinking of building an automatic integra turbo in the street. I know this is ideal for the track,but I'm wondering how it will run in the street.Does anyone have any experience doing this or is it a bad idea?

It's basically I don't understand how the ems will work with the shifting will I have to wire the shif solenoids manually to a hondata, or will it continue to run normal with the stock ecm?????????

 

More importantly what honda auto tranny can hold any power?

 

None. Any performance driving on a stock auto Honda can lead to failure early, add boost and tons more power/tq between shifts and it will heat up, slip, and die. And as far as I know, Hondata doesn't support it either.

There was thread a few months back about people who had boosted auto's and they didn't work. Can someone explain what exactly it is that makes them not hold the power vs other companies auto trannies?

would a seperate/real tranny oil cooler help with this? I have a d16z6 w/auto tranny sitting in my garage...hmmm...it could be fun...haha

 

honda's doesnt, trannys are not pressureized like most other companys,no valvebodys. i worked for acura and i had to replace 4-5 of the v-6 auto trannys a week. it was the suck

I wish i could read this.

 

that better

 

A friend had an DC2 LS Integra auto and put his old turbo kit on it for ***** and giggles. On 6-7psi, the tranny took a **** in literally 3 days. He probalaly got on it a total of 20 times on the beltway 5-6 seconds each.

get this ****, funny i stumble upon this thread.

I have a friend that bought a auto turbo LS. He claims the previous owner had the trans built by someone and he says it definatly shifts harder than any stocker. It also has a 2800 stahl in it, lol. His problem now, is trying to find a fuel managment system that works with an auto ECU. Crome, neptune, anything? i know hondata doesnt...

 

AEM will...

 

for what it costs for AEM i can convert his car to 5 speed and have a ubergaydata 10psi basemap loaded into his ECU. I heard with AEM you have to buy additional solenoids that have to be somehow wired it or whatever. Sounds like a complete mess if you ask me...

 

thanks for the input guys!

so far I 'm understanding that it's good and bad I know now it dosen't run with hondata,neptune, ect. but wat if you left your stock ecm and ran a secondary stand alone to read boost I know this is not the best thing to do but for the $$$$$ it seems like the only thing, because I really want to try this. AS for the cooling part of the tranny I am going to istall an after market cooler and run it in series with the stock one that runs through the rad. or do you guys think that no matter how cool you run the tranny it will blow no matter what. there's so many advantages to running auto. turbo and my teg stalls at 2600 it will build boost at a red light nicely! also my plan is to run low boost like 5to 7 psi because rotating assemby is stock for now!

Yes. Heat will kill the tranny and even with a huge cooler it will fail. There are aftermarket companies that sell clutch packs, coolers, ect but nobody has been able to keep one together. Wish someone would find a way to make one last...

Exactly. Honda automatics are very efficient . I build clutch plates for auto transmissions out of powdered metal. I cnc these parts and clutch hubs so i have a little background. They are very much like manual trannies inside except the clutches are inside not where the flywheel is. Most strong automatics use a planetary carrier and planetary gearset. Hondas do not. They gain efficiency by following the manual transmission design principles and doing so limits the amount of area for the clutch packs and thickness of the gears. This limits the strength of the transmission and there for premature failure. Also the coolers bring the temp down after circulation. The heat where it is generated changes very little if there is slippage. There is simply not enough room for a chevy sized clutch pack. Hope this is helpful.

 

.....IMO, its a waist of time and money. automatic honda trannys hate boost,
and it doesn't matter if use after market oil coolers, or torq. converters, it will not last. So go 5 speed and use hondata and it will be cheaper and last longer. IMO

 

so from wat I understand honda automatics suck boosting. so I'm dying to start fabing my custom set up, so for now it's auto. when the tranny go's south I'll convert to 5spd. but I,m still excited to run the auto in the street...for a bit. if I figure a way to keep it together i'll post it up. i'm still looking for other peoples experiences with automatic turbo.

 

i loved my gutted eg hatch with stock ls turbo auto. the tranny lasted about 2 months. i was drag racing it at the track once or twice a week and beating on it all day everyday. the amount of boost ran was only 6-8 psi. odds are it won't last and you will be doing your five speed conversion.

 

have no exprience with a turbo auto, but my n2o auto has held up all season in pure stock form,

reasons i guess this is
car weighs about 1700 with me in it,
motor is a d series so torque is low
and i dont load up the converter more than an extra 400 or 500 rpms for no more than 5 seconds at a time (in the time it takes to build suffeicent boost at 2600rpm id imagine the trans would crap out real real fast)

ps car is a track ***** ran a 13.70 in the 1/4 the one time i took it to a 1/4 and has made about 70 , 8.7 sec 1/8th mile passes plus a few hundred 9.9 1/8th mile passes and about a dozen 15.3s 1/4 passes ( trans still works awesome plan on using it next season as well)

 

why bother.

 

well if all you guys are beating your automatics at the track and there holding up for a month or two shouldn't be so bad in the street. anyways I'm building it for fun not to race with, that's wat the drag car is for! we also want to try a turbo on top of the manifold set up, because noone around here has a set up like that I'll probly be the only one!

why not bother? you do not know what will work unless you try it for yourself and do the very best you can to fix the problem and not give up. THere is a guy on h-tech that has a civic with a h motor that runs 11.70's with a basically stock auto tranny. The reason he does not have a manual trans is he physically cannot drive a stick. If everyone has the mindset that something will not work then it will not work. But for some people telling them it can't be done adds fuel to their fire and the work harder on the problem until it is fixed. I am going to use a auto trans in my honda. I have already worked out clutch issues and add 66 percent more holding force on the drums and have worked out other issues such as shifting and stall speed. I have confidence that the auto trans with some R&D will work and will become the trans of choice in the near future.

i like your mentality. so what exactly have you done for the extra line pressure? and what are you doing about the shifting? the people who so strongly disagree with automatics have probably never drove or messed with one in a setup with a good power to weight ratio going. you would be surprised. there is a difference in a slow auto and FAST one . for the street (if you are into putting your life and others at risk), it's great...traction control galore. it's not any slower and it's not less quick than a manual. i would love to run a beefed auto with modified line pressure and a switch setup to shift it...with a big motor and a lot of boost. the only problem i might see is not being able to 60 foot that hard. also, something needs to be done about strengthening the oil pump. i believe there is a lot of potential with a automatic...maybe just not a honda auto though.

 

my mom's 2004 V6 Accord automatic just plain ole boogies ... I have fun with that car everytime I use it ... LOL I swear I can get it to run a high 14 sec pass

you can run a 96+ LS auto tranny just upgrade the torque converter since that prolly takes the most abuse.

To up the line pressure I shimmed the pressure relief valve spring up some. Annd to make it shift i am using a 12vdc industrial programmable logic controller . I plan on changing to a more sophisticated controller next year. I built a custom stator for the converter and hope the converter will stall in the 4000-5000 rpm range. I added extra clutches in 2nd gear. 3rd i can add 1 extra but i plan on trying it like it is and see what tears up and keep fixing it until its right. I think an auto trans car will 60 foot better than a manual with the right boost control.
