only 900... damn though

 

By looks do you mean visual or quality? Visually it actually looks pretty good.

Quality wise it looks like a better then average made china piece. Only time will tell if it holds up.

Yep thats the pull for it, so cheap it is hard to not pay attention. Plus you save the money and hassle of the oil return ect.

Either setup will work, the top mount will give you better performance obviously but really comes down to what you want.

Most important thing for either setup is properly matching the turbo to the goals and of course proper tuning/fuel mods.

 

well imo im not looking for a race car man, just want more power 50-100hp. for hauling, general show-boatin the nice newly painted engine about

 

Well like I said, either setup will work, just depends on what you want. Either way fuel mods are a must unless you make so little extra power it is not worth the hassle. By 180-190whp the stock injectors are maxed out, everything after that will have you running leaner and leaner.

Gadget did tests a long time ago and even with the stock supercharger with a pulley his EGT's would get up to ~2000f degrees! The engine lived and ran due to how stupidly overbuilt they are from toyota but that sure as heck ain't good for it.

 

Well is there a retro for kit for putting he 1uz injectors on the 3.4 or what. I don't wanna spend 700$ on a new fuel system.

 

Putting larger injectors on the 5vz is not a good idea IMO but do whatever you want. Tuning is the #1 most important step to getting the most out of a setup and it lasting. Not the place to skimp IMO.

A rising rate FPR with a high flow fuel pump could buy you a little power but not that much.

 

Then how am I gonna figure out the fueling
Problem. If I need more fuel into my engine.

 

Not sure I understand? Thats the point you need fueling mods if boosting the 5vz.

 

what type of fuel mods are you suggesting then?

 

Up to you, lots of choices with varying degrees of quality.

Always got the URD fuel rail with a piggyback option. While this works fine I think that a replenumed manifold should be a given for a turboed 5vz and not sure this would work with it.

You could use an AEM FIC with some larger injectors, if you can get the sensor signals cleaned up and working this is a real good option.

Could use heavy amounts of 100% meth injection like I did but you need access to drums of methanol for cheap.

Could go with a 7th injector style setup although the prior options make more sense in this case.

Then you have the best option of all, complete standalone. Although this is overkill for what you plan I think.

Really comes down to budget and what you want.

For a piggyback setup my choice would be an AEM FIC either with an extra set of injectors or a larger set.

Meth injection is what I personally used with GREAT success but that is not for everyone.

 

Not having any luck finding my answer, but where do I hook up my fuel pressure regulator to in a turbo application? I keep seeing "hook it to boost port" with a supercharger, but not being familiar with the supercharger- is that only a port that sees positive pressure when making boost?

So then where should I hook my fuel pressure regulator on my turbo application?

 

The FPR just needs a port post TB in a turbo application. Any will do, it needs to see both Vacuum and boost.

Although honestly you really don;t need an aftermarket FPR unless you are trying to stretch stock injectors with a much higher flowing fuel pump.

 

Perfect, thank. I'm using factory FPR.

 

 

OK, I was wondering who was posting the new turbo 4runner videos on Youtube.... I forgot Youtube made everyone change their name. Good stuff!

 

I'd like to bring yet another discussion back from the dead.

I want to revisit the BOV vs no-BOV issue. After lots if reading on the subject, I also agree that going BOV-less shouldn't hurt the turbo (theoretically). But let me ask this, wouldn't the lack of a BOV screw with water/meth injection kits?

For example.... Let's say my meth injection cuts on/off at 4psi. If the turbo is pushing 8psi and I close the throttle, the pressure in the charge pipe will gradually fall, instead of immediately being discharged by a BOV. During this time of the pressure gradually falling, it seems the water/meth would still be injecting, due to the pressure switch still seeing boost, even though the throttle is closed.

Seems like a problem?

Cavitation?

Compressor surge/stall?

That's what happens when the pressure differential gets too high on the compressor, and the blades stall out and stop moving air. When that happens aid can move backward through the turbo. Also, when the blades stall out, the drag on them can drop and the turbo can overspeed and damage itself.

 

Nope, no problem. The meth injection should be reading the pressure from the intake manifold, with the throttle closed there is no boost in there.

Close but not technically correct IIRC, been awhile since it was explained to me. It is good enough for this discussion though.

Sorta, the blades never "stall" in the sense that they stop moving. They will Cavitate.

Overspeed is impossible when there is no torque being delivered to the turbine to drive the turbo such as is the case with a closed throttle.

On throttle surge can do this and is part of why it is so bad and a turbo killer.

 

Texas_Ace, I'm also in the DFW area; would you be willing to get together sometime to help walk me through this stuff?
