Boosting a slushbox ?
 
There's a kid I work with who want to do all this stupid ----(header, intake, vtec head basic bolt-ons) to his car that won't help it out that much being that it's an auto. So I told him your best bang for you buck would to turbo. It's an auto EK DX hatch. I was thinking since it's an auto that a small turbo would be the best since it's gonna shift early with tranny. I was thinking like a dsm t25 or maybe a rhb5. Nothing crazy just a basic kit. I told him I could make it and install it for 600. Since it's obd2 I would just go with a bluebox and keep it simple cause even though it's a simple kit I'll never resort to a FMU and check valves. Any suggestions on how the car would be boosted on a auto tranny?

does it matter? it will be an improvement - dont u guys have anything for mapping auto boxes and their shift points? ive seen them for supras etc

It's obd2 so anything with the ecu is a no-go. Just not sure how the converter would take it and how long?

so this ain't smog legal then...would this be a real pain in the ass or something that can be taken care of relatively easy?

slushbox will die w/in a few months.

Dpends on how hard he is on the tranny. I saw a post a while back with a guy who was running a F22 or something with a small lil snail with an auto tranny and babied it for quite a while and it held up untill he sold the car. You can do it, it has been done but eventually, it will die. Just depends on how hard he beats on it and what snail he runs...

Well I'd be build the kit so I'm trying to get ideas of a good turbo for it. I'm think around a IHI rhb5. Any other suggestions?

not that i know anything but from what i've read, the IHI rhb5 would be a decent choice....that's what i was thinking of going with but still usnsure about the obd2 deal...

he is going to need to baby it for sure. From what i've heard more than probably 5-7psi with a small turbo is going to be fairly rough on that tranny.

Does a turbo really mess with an auto that bad? I didn't know that. What about the turbo auto cars out there. Like my buddies old 1G Talon. It was turbo auto. How's 5 speed make it different?

those honda auto trannys just aren't meant to take that kind of power.

Re: Boosting a slushbox ?
 
ive seen lots of auto trannies take a ---- w/o even any FI.

my auto tranny took a ---- after 2 yrs of very light nitrous use, now imagine what a turbo would do.
my best mod has been the manual conversion, then turbo.

so say a greaddy kit that's for a stock set up would still be too much? what about backing off the boost a little? i would be cool w/2 yrs of tranny life cause that would allow me to scrape together the parts for the 5 spd...i'm a noob at all this so i don't know...

Re: Boosting a slushbox ?
 
i think a greddy kit at stock boost would probably be fine. Just don't beat on it too much.

Re: Boosting a slushbox ?
 
if your gonna do it id suggest a tranny oil cooler and changing the atf w/ honda atf very often.

i only got 2 yrs out of it cuz i sprayed maybe once or twice a month w/ a tranny oil cooler. but the constant abuse of a turbo i doubt it'll last as long...

Re: Boosting a slushbox ?
 
i don't plan on using any spray....yet...if i do, i will definitely do the tranny swap...i may start looking for the pieces now...

Re: Boosting a slushbox ?
 
my experience was with spray alone. im talking about any kind of forced induction.. honda auto trannies just arent stout enough.

i was making a comparison between constant boost vs my 1 - 2 sprays a week, the turbo will own the auto clutch packets unless you plan to drive out of boost most of the time?

get a 0bd2 to obd1 conversion harness for your ecu woes, and if your radiator is a radiator/tranny fluid cooler, please seperate them. if your tranny goes up, so does the motor and vice versa. an auto should be so lucky as to die at the spool of a turbo. boost it till it craps out and then swap in the manual.

You could use the money you would spend on a "Greddy Kit" and you would have enough to do a tranny swap and turbo kit the HMT way. Some of you guys are afraid to build your own kit, cause you say you can't weld, or don't have the tools, whatever. You can do an intercooler and charge piping with very minimal welding, that is where some decent couplers would come in to place and I think everyone can work a hacksaw (not that it would be the easiest way to cut pipe) You can JB-Weld a BOV flange on if need be and you would just have to get somebody to weld up a DP for you. You can practically build a honda with a couple of metric wrenches. Read and see what others have done, chances are if you can think of it, it's been done by somebody on here already.

i was kinda thinking the same thing after going thru a bunch of posts and the faq's so i'm gonna piece everything together now...thanks all.

I think a IHI rhb5 setup would be less powerful than a Greddy kit. Even though I believe there setup at 7psi it's a such a small snail that it would compensate for the psi being high. Also isn't thats what the dualcore is made for? A tranny cooler with the inlets for it already on the bottom of the radiator being that it came in the auto setups and b16 delsol's?I always thought of running my coolant lines from a turbo to those but it wouldn't circulate so it wouldn't be any good?

I ran a tdo4-13g out of a auto 1g dsm.My car was a crx with a zc AUTO.The tranny is now starting to slip over 2 years after i sold the turbo kit and the car to my parents.When i bought the turbo and it had been ported and clipped.I ran dsm 450's,afc,and a wally 255 for fuel.Car made 215 hp,187 torque at 15lbs of boost without pulling fuel and a water sprayed dsm sidemount intercooler.I say go for it and $600 sounds kinda cheap to do all the work and buy the parts.
