Your optimal afr is around 6 to 1 instead of 14 to 1. You would need a wide band oxygen sensor too. Other then that shouldnt be to much of a difference. It sure is cheap though there are a few issues. I dont know why the goverment doesnt try and use it as a altenative fuel. Well I do, its toxic and its very water soluble. Nick

Taps are tool steel so there very hard. A normal drill bit wont even cut them. If you could get it cold and hit it with a punch it will break easy. Used some canned air with the can upside down so the liquid comes out. Spray it on the tap for a few minutes the give it a few good smacks. If that doesnt work you need a diamond cutter or a tap extractor. On a side note you can dissolve it with nitric acid. It wont do much to the aluminum but it will eat up the steel. This is what a lot of machine shops do when they break off a tap in non ferruos metals. Nick

Thats seems a little high to me. Depending on what needs to be replaced though. Nick

I measured it and gor a radial play of 15 mils. By the limited info I found this seems within spec. So I guess once balanced I have a working turbocharger. Thanks for all the help. Nick

I goit the rebuild kit and I put the turbo together. There is a little radial play in the shaft but it doesnt make contact. Is this normal or not? Thanks, Nick

Oh cool, Ill try that, thanks.

Did that guy Jermery, did he use to work at road worriors? Nick

Just the usual if the engine needs it. Im hoping I wont need the block bored or milled. But other things like disassymble the engine, hot tank it then tell me what machine work is needed. Then a valve job. Thanks, Nick

The inducer of the ompressor is a tad under 3" the exducer is 2". The turbine sides excuser is a 3" v band connection and the inducer flange is a t4, so what ever the dimensions are for that. I am going to put a new scroll on the turbine side though, with a higher a/r. nick

Im going to need some machine work done soon. But im not sure who to use. I know theres some houston z club guys here so I though I would ask. Just dont know if there a shop that specualizes in nissan stuff. Just hope I dont get taken to the tool shed. Thanks, Nick

Ok so I found out exactly what this turbo is now. Its a to4e02. Does anyone have any info on this unit? Also the thing had been sitting in a garage for awhile and there was junk built up on the compressor wheel. I was able to clean most of it off by putting it in a ultrasonic cleaner with some soap in it. There is a little bit of corrossion on it too. WIll this be a problem when I take it to get balanced? It was off of a 2.6 liter diesel. Im guessing it probably wont work to well for a high proformance engine? It has an a/r of .50 on the compressor and .41 for the turbine.These numbers seem pretty small to me. T'll probably have to put somehing bigger on the wont I? Thanks Nick

ouch! No thanks. My friend wants to run a car on hydrogen. I fixed him up with an electrolyzer that can produce 1.8 liters per minute. I sure as hell wouldn't want to do that. As you mentioned, h2 embrittlment. Ordered a rebuild kit today. I took a gamble since I'm not 100% sure that this turbo is what I think it is. It spins ok and it doesn't look like the turbine or the compressor fan rubbed anywhere. There is a little radial play in the shaft though. But its slight. I finally got off the exhaust scroll but I can't get the it loose on the compressor yet. I poured some atf on it and I will try again tomorrow. nick

Try hydrogen,LOL. I used to work with high pressure water electrolyzers. Scarey when you think about it. And these things went on submarines. Small atoms, itty bitty spaces.

Hence why they use heilium to leak check vacuum chambers. Ill just make sure the mating surfaces are very clean after I rebuild her. Nick

Thats what I thought. Just wanted to ask though. Thanks
