Ebay 5vz-fe Turbo

[White 4x4runner]

Ive been tuning cars since I was 16. I would build my own map for this car, as long as I had a wbo2 I would be fine.

I don't know the experience you've got. I said ya gotta know what your doin or pay for it. You know what your doin so that's a leg up. I've been building and working on cars for a long time but i leave the tuning part to others. Good to have friends that own performance shops.

Dude, I think you're totally missing the whole point here. Our trucks aren't race cars. We don't need huge turbos to make big power on the top end. We need/want low and mid range grunt. My truck has only seen the big end of my tach on a few occasions, so I couldn't care less what it dyno's or makes for hp. We're not turbo'ing our trucks to have dick size competitions at the track, like an all out racecar would be. Those guys don't care what power the car makes in low/mid RPM's, they're all about top end. You're severely missing why we're looking to add turbo's to our trucks. Would a small turbo on our trucks be very inefficient in the upper RPM's? Yes. Would it be awesome for low and mid RPM applications, such as EVERYDAY driving conditions require. Absolutely.

Actually for what our trucks are for the stock motor is perfect, anymore power just makes you have less traction on the trail. This kit is made to make power, not just a little extra. If you want that then get the supercharger, its low end tq and perfect psi, why put the turbo on and run the same as the supercharger, this kit is to make power and is geared towards the mini trucks.

So true, but thats how I learned, my buddy has one of the largest Mitsubishi shops in the US. I learned from burning up two motors when I was younger and just reading a lot online. I have tuned many cars now and love it.

AEM is not a piggy back, it completely takes the ecu out and you replace it with the AEM unit. Piggy back is like the SAFC where it just wires into the ecu and tricks the ecu into seeing a different air flow reading from the maf. The aem uses speed density so for tuning you would need a gm bar and air intake temp sensor.

I think he's talking about that AEM FIC

which is why we're all saying the turbo supplied in the kit is too big. And with any positive displacement blower, boost is going to be instant, so trying to say traction with a turbo is going to be worse than it will be with a blower is totally moot. I think it's safe to say we are going to agree to disagree on this one.

Interesting concept but I've been saying it for years;

Regear! Boost your low end torque without compromising your 150+k mile engine's reliability.

Built for it or not, boost (especially a little more, because we always want just a little more) reduces engine life. But a set of gears makes the engine work less.

In my opinion, I think a small turbo (T3/T4) would be superior to the TRD supercharger. Sure both can make 7psi, but you'll see more gains from a turbo with that 7psi than you will a roots blower. The parasitic drag of the blower robs you of more HP. And if you ever want to turn up the boost, it's much easier to do with a turbo than it is a supercharger. None of that swapping pullies nonsense.

As far as spool time, check out Clownmeat's turbo thread. He has a rear mounted T3/T4 if I remember correctly, and experiences very little (if any) lag. I can only imagine what a front mount would be like.

Just my two cents.

All turbos have lag. Even the guy I know running rear mounted on his LS1 V8 has lag. No lag only happens with a supercharger.

Ohh sorry, I wouldnt think of using that at all. Piggy backs are junk, they cause the timing to raise because the ecu is tricked into seeing less airflow causing the motor to think it can add timing and then you get detonation!!

The point was that there would likely be very little lag if you went with a small turbo.

lag has nothing to do with the engine. It has to do with the size of the turbo. Granted, yes, some lag would be present, no matter where you mount a turbo. With the RIGHT sized turbo, lag can be made damn near non-existent. As a matter of fact, it can be made so close to non-existant, you'll never even notice it.

With this, why is lag such a horrible thing anyway?

I mean, I see the point of instant power with a sc - thats pretty obvious. But realistically, for those doing a lot of wheeling or crawling i.e., what difference does more hp really make? Youre always moving slow while crawling and the main concern is finding your lines and keeping everything in control. More power doesnt accomplish anything in that scenerio, other than lead to broken drive train parts. More power comes into play when you get off the trail and jump on the highway with your 33s" and lift and youre climbing a hill on the highway or driving at high elevation or towing something. If Im crusing down the highway at 70 the turbo is already spinning and lag will be reduced when I hit the gas to pass someone, correct? Really what difference does counting "one-onethousand" in lag time make in practical scenerios? It seems that the issues people have with the turbo are in the mindset of racing, or creating really large amounts of hp. I have no intention of racing my 4runner ever, or driving with a lead foot. For practical uses when kept at 7 or 8 psi I think the turbo seems like a great option

Piggy backs are not junk. I've personally used them for several years in upper 6-700 hp range without any foul issue.
BUT could you squeeze out more, more efficiently out of a stand alone? Of course not going to argue that in the least bit. Is a stand alone better? Yes.

But back to the AEM FIC or any piggy back for that matter. You will have issue's tuning with an OBDII car. The factory ECU will learn the adjustments made and in time will correct itself back with factory parameters, There are ways around this yes and some companies make separate things around that but by the time you figure it out and the cost of the parts and tuning you're already in stand alone $$.

I could write a book on this subject but I kept it short and simple and hope that the point got through to some wondering.

CX Racing ( as well as Godspeed, SS Autochrome, OBX, etc.) and those blue ebay couplers are two HUGE reasons to be weary of that kit.

Rather than buy that, I'd put together my own kit out of quality parts, then look a turbo with a name brand like Garrett or Borg Warner. That Chinese turbo WILL blow shrapnel into your intake. It's just a matter of how long until it happens.


also, FWIW: My turbocharged RX-7 achieves full boost (about 12psi) by 2k-2500 rpms. Basically lagless when the redline is 9k+.

 

[white_n_slow]

I have seen people run those cheap ebay brands (OBX, Megan, etc) on Hondas and the typical results are cracked manifolds within a few months to a year, and within 2 years enough cracks and problems to be beyond repair.

That said, people who make their own bracket to hold the weight of the turbo do not have the same problems.

I can see buying the manifolds and shoring them up being a worthwhile endeavor. The problem is (especially with a v6 and tight quarters) that it's so hard to get a manifold that fits well without relocating half the engine bay. Then buy a real turbo and get on the dyno to get everything mapped out. Buying the whole kit, you'd end up with a lot of garbage to throw away.

Exactly. A nice smooth onset of boost/horsepower is much easier on parts vs. instant power like a shot of nitrous. Turbo's make boost based on exhaust pressure, so even revving a turbo'd motor while in neutral will not typically produce much boost, if any at all. Loading the engine, like brake torqueing, will make boost. So if your engine is seeing RPM, but not under much load, boost will be minimal. If it's working in the RPM range, it'll make boost. So with a turbo, you really only produce boost when you're loading the engine.

Built for it or not, boost (especially a little more, because we always want just a little more) reduces engine life. But a set of gears makes the engine work less.

A small amount of turbo boost can actually increase engine longevity. It doesn't work as hard to create the same hp output, thus reducing the need to rev to achieve the same results as an N/A motor. Turbo's aren't new people, semi trucks use them and see a million miles or more before a rebuild, so saying you won't install one because it decreases engine life means you're plain misinformed.

Ummm....

Does anyone else wonder why this is so ridiculously cheap????
