i did a search already, and found a lot on ls/vtec, but not 2 much on automatic ls/vtec integras. i'm thinking about putting a gsr head into my automatic ls. i already got my hands on a jdm auto ecu, and i'm going to pick up a ls/vtec conversion kit.

i realize i would get better response with a manual transmission, but i am not doing a transmission swap now.

is there any other parts i should pick up, or anything i should know about doing this on an <U>automatic</U> integra.

any help and advice is greatly appreciated! thanks

 

The head has absolutely nothing to do with the transmission

 

I'd be afraid that the auto trans would limit your rpms...honestly the only auto honda I've driven is an Accord...so I might not be right.

ya, i know wat u mean.. but, i could always get a vtec controller, so it kicks in sooner.

 

since u have the ecu you are good to go........this would be the only diff between an auto ls-vtec and a manual

Yup that would probably be the most difficult part is locating a Auto VTEC ecu but since you already got one everything else should be the norm.

 

Where did you get the ECU from?

 

alright, good! i just wanted 2 make sure!

Ebay

 

I think there is a cable that comes off the TB or something and runs over to the tranny that you might have to adjust to get the shift points right. Other then that it should work fine...although you will have to wire in the extra stuff for the vtec head vs. swapping to a gsr wiring harness due to the auto part.

 

hey could not help noticing (lquid ice nf) u from newfoundland or are you coming here to dj cuz would love to cheak it out

 

would the ecu allow him to rev that high? Since I have very little background with autos, I might be speaking out of turn, but I thought it might hinder his ability to wind out to 8k...again, I'm quite possibly wrong...

 

gsr auto ecu from japland....redline is at 8k

So it would only go to 8k if u had the pedal to the floor right? utherwise it will shift normal.

 

ok, bu what I'm getting at is this...will be able to run the car that high into the rpms with that trans...maybe I should have clarified...lol

 

idk what's gonna happen when the vtaaccc kicks in

 

Why would you even want an auto ls-vtec, really. I'm not trying to knock on you or anything, just curious what the reason is.

 

Yes, the ecu/cable controls the tranny, so it will let the engine wind out until told otherwise by the ecu. Im sure he wants to do it for one of the following reasons:

1) To say he did
2) He cant drive a manual
3) He doesnt want to drive a manual due to traffic
4) He bought an auto and now wants more power without selling his car
5) He bought an auto and doesnt have the cash/experience to do a manual swap yet
6) His parents wouldnt let him get a manual, so this is what he's stuck with

 

its gonna be super slow w/ an auto...

but since youre goin through all the work of building a motor, why not go swap the tranny too???

 

you can't just set vtec to where ever you want....you need to dyno and see where your car should have it engage. if its to early it'll hurt you and if its too late you'll be losing power too

 

Actually I was thinking about it and honestly with the ultra long gears in that auto tranny a turbo might be much better. With the raised redline 2nd is going to top out at like 80-85ish

Mostly #4 and some #5.. i have no idea what 2 do for a tranny swap, and i dont want 2 spend the cash havin someone else do it.. i have a friend who can help with the head, if i even go through with it. This is my first car, when i bought it over a year ago, i wasnt too concerned about auto vrs. manual, b/c i didnt know better.

i'm kind of having 2nd thoughts now.. i dont want to risk damaging my car, ya know?

but anyway, thanks everyone who replied!

 

I'm running auto-LS VTEC.
best time is a 15.6 so far I use a VAFC to control the engagement.

Thats much better then I would've expected to be honest (auto gears SUCK). Is that with stock cams and bottom end? Bolt ons?

 

I have the basic bolt ons I/H/E. Nology plugs, stock ignition, AEM sprockets set at 3-2. Header back straight pipe. B&M fuel regulator, Stock bottom end, VAFC to control the VTEC and fuel tuning. Full Buddy Club body kit and a 3 piece wing too. OEM hood also

I shift 1-2-3-D when racing.

I never seem to get to D though.

with the ls/vtec it would not be safe to run the engine up to 8,000 the r/s ratio on the ls motor is way different that of a gsr motor. so the bottom end is not set up to be reved up that high
