Yeah I didn't know that either kinda sucks

I'd rather have a little slower of a spool and a turbo that will make the same power, last and be able to be rebuilt cheap.

Yep but for many who don't want to add parts like different charge pipes and a bov, the zfr is appealing. Seems like a great turbo, just short lived on some of them.

You can buy a s257 or s259 Kit plus an upper CP for about the cost of a 7163 tho.

The 257 looks like a great turbo. Wouldn't want to have to deal with that power though. Would be fun, but I care too much about 0-70 more than 70-140. You would really need to rev out pretty far to take advantage of that turbo.

That kit is like 1000 more than the 71. I'd need the upper cp and I don't know how I'd run meth with the maf in Lower cp. if it was same price is go for it

Have you pulled the turbo or checked for shaft play?

tomj77

iTrader: (2)

I have not. since that takes a bunch of time, that will be the last thing I do before I buy new one. there is non on the compressor side, well very very little that u can hardly feel anyway. I guess I could just pull the o2 housing off to check for play, wouldn't have to take the whole turbo off. that would be easier.

I would certainly verify it's actually blown before you go buying another one. It definitely sounds like it could be the turbo, but like slowbalt2000 said his was smoking and it was valve stem seals. Not sure if a stuck IM pcv could cause the same issue, but it certainly could given higher boost levels of a zfr and you even said you're driving it hard.

tomj77

iTrader: (2)

Yes I know, but I have a few other tests to run before I dive into that headache . Just waiting on some parts and a leak down tester that's on its way. I was thinking valves to but all the other signs of valve seals arnt there, but yes I will make sure it's the turbo before I spend 2k on a new one.

Oh and the zfr actually has 16k kms on it, not that that's much different than 10 lol

63 Nova SS

iTrader: (3)

So that's like 10,000 miles? That's terrible.

tomj77

iTrader: (2)

you something like that. 10k miles of hard abuse though.

sev

I am having the same issue but mine only has about 1100 miles.
I bought another one that I hope shows up today.

tomj77

iTrader: (2)

Oh ****. That one should have warrenty or something on it. Let me know what u find. I'm gonna be driving nice for a while. Iv tested it for a few days, absolutely no smoking on normal driving or even up to 5 psi. As soon as I get into hard boost, then come to a stop, few minutes later. Clouds of white and blue smoke lol

sev

Same thing for mine, no smoke or oil loss if driven out off boost. If I get on it then it smokes everywhere, just clouds of smoke and pukes out oil.

Warranty on turbos is a hit or miss really, thats why I just bought another one.

I'm thinking of getting the s256 kit, don't know how I'd run my meth then though, since the maf will be in lower cp. but I would rather have it since that turbo seems more reliable and safer with its less instant boost

sev

I have rebuilt journal bearings turbos with bearings I bought off ebay and beat the crap out of them with no issues. I abused the hell out of the factory K04 with no problems either.

I bought another efr so lets see how this one goes.

Tap the IM
Spray behind the MAF
Direct port meth

tomj77

iTrader: (2)

no room really to spray behind maf on zzp pipe. intake mani is an option. I have a direct port setup on the bench, but it scares me, if I loose flow on one of the nozzles, could hurt things

tomj77

iTrader: (2)

ya I beat my k04 to, but it was getting shaft play already. I just wish the s256 wasn't so expensive for the kit. or the zfr would be cheaper if they don't last that long.

Ask Josh for a deal on the s256 kit; he has been looking to move stuff out recently.

Do it 5th injector style then.

sev

You said you were getting surge?
Maybe these things are real senistive.

They say they are not rebuild-able and that may be true for the bearings but I dont see why the oil seals couldn't be replaced.

who is this josh? ya id probably drill and tap a hole just above the tb.
