I'll try to make this short. In the middle of my 20 mile drive to the local 1/8th mile track friday night I had a breakdown on the interstate. My NGK/AFX wideband was installed in the glovebox when I got the car and all of the extra wiring was stuffed uner the center console and the harness ran through the shifter boot to the o2 sensor in the exhaust. Well I hit a bump on these rough Kentucky roads and the harness got tangled in the output shaft on the transmission and wrapped all 15ft. of harness around the output shaft and made one hell of a racket until I got here stopped. I had no idea what had happened so I had a buddy of my come trailer it home. It took 1hr of cutting and pulling with channel locks to get the birds nest of wires off the output shaft. I drove the car when I got it clean and it seemed fine except when I got back it was leaking gear oil out the output shaft. It destroyed the rear seal.

I am wondering if the rear seal on the SR transmission and the KA transmission are the same ??? I would think that they would be but not for sure.

I am going to put it on a rack tomarrow and try to get it fixed. any advice on removeing the output shaft? Here is a pic I stole, not my car.

I got a rear seal for a KA transmission at Oriely's for $6 and I hope it works. Now for the real problem. When I got out of the car after it broke on the interstate I poped the hood and the turbine side of my turbo was glowing like a light bulb. I mean no sh@# it looked like a cigarette lighter and the bottom half of my manifold was glowing red. WTF??? When I drove it down the street and back today it boosted fine but I didn't go a 1/4 mile and never got out of second gear(transmission still leaking gear oil). I am running at 20psi and I only have about 4k miles on it since I got it but I don't know if it was used before it was put in the car? I could have oil feed or coolant feed problem but I am not leaking anything and can't see any problems with the lines.

1. Is it toast? If so, why is it still boosting fine?2. How do I make sure that I am flowing oil and coolant into and outof my turbo?3. Do you think the wideband harness wrapping around my output shaft could have had anything to do with my turbo getting hot? It made a hell of a racket at 80mph but I pulled over immediately and only drove it on the trailer after that. I wouldn't think so, I think I have to seperate problems but IDK.Looks like it might be time for the GT30R.

Looks like it might be time for you to sell your car!!!!

Anytime you have engine harness wires from your car running close enough to your driveshaft to do something like you are saying it did makes any sensible person wonder why you would even try to work on your car by yourself.

To answer your question about the turbo well guess what--- it is running off the exhaust and as such can get glowing hot from the exhaust gases being pushed through there-- You are boosting your engine to 20lbs which is 1.3 bar and I would expect it to glow like that. It is possible that the wires you pulled out might have had an effect on the air flow and could have gotten it to dangerous levels if you have a rom tune then it should be ok--

To answer your question about the turbo well guess what--- it is running off the exhaust and as such can get glowing hot from the exhaust gases being pushed through there-- You are boosting your engine to 20lbs which is 1.5 bar and I would expect it to glow like that.

you sir should shut your noob A$$ face and step away from the key board and watch what comes out of that smart A$$ mouth of yours! and if you red he only got the wide band wire caught cuz it was to close to the drive shaft. not his WHOLE WIRING HARNESS!!!! now to the problem, im almost positive the KA seal with in fact fit your SR transmission. cant hurt to try. and as for your turbo glowing. were you boosting it alot on the high way? how long were you driving?

hope dumb **** here shuts his mouth. oh and FUC# HONDAS! this is NICOCLUB home for the nissans

For your information; I did not red or is that read his mod lists before I posted those comments. Thanks for taking 3 posts pointing out my newbie comments. Maybe then you can pm the OP about the proper ways to wire up the birds nest that ended up wrapped around his drive shaft.

I didn't run the wideband harness through the shifter boot and would have never done it that way if I had put it in the car. It was like that when I got it but I should have put a couple of zip ties on it when I saw how it was ran. OH WELL, spilt milk now.

For the turbo, no I only hit full boost when I got on the entrance ramp coming around a semi and had driven several miles at 75-80mph in 5th gear before I broke down. I don't drive it to hard on the way to the track because it was like 78 degrees Friday night at 11:00pm down here and I don't like setting for ever to let my car cool down when I get to the track. It ashed the flange on the manifold and the turbine is very discolored now and I won't be able to really test it out until I put the rear seal on the output shaft tomarrow. I just want to check my oil and water lines and look it over before I push it hard. IDK what's up with it but it has never gotten hot like that ever, not even on hard country rides boosting the entire time.

If I have to replace it this is what I will be going with.......http://www.atpturbo.com/Mercha...e=GRT

With the .64 AR it hits full boost at about 4200rpm but is easily capable of maxing out my 72lbs injectors. The GT3071R with .86 AR on garret's site is rated up to 480hp and the GT3076R(WG) with the .64AR is rated at 550hp. I should be able to run this turbo conservatively and still push 450-500WHP on 93 with my new cams and intake. Not to mention the water/meth injection.

yeah the .64 will boost earlier that is for sure. If it gets hot were you are and I am assuming Kentucky then yeah the water injection system would work well (awesome on Stis). Hell I am thinking about doing it to my car and I am only pushing 260-300 horsepower. I kinda don't want to get into bigger injectors, larger turbos, and tuned ecus since I occasionally get 28-32 mpg..... I want and need my mpg....
