Im wondering if anyone knew a place that sells or makes a 5vze 3.4L turbo exhaust manifold. I've been searching on yahoo but to no avail. Maybe you guys know a place that has one or can make one for me. I always like to do a bunch of research before jumping into a project.
Thanks, Gene

 

I know you asked specifically about a "manifold" (I will give you the benefit of the doubt and assume you left off the "s") since there are two you will need.

I am not aware of a readily manufactured turbo manifold for each head on the 5VZ, however STS makes a remote mount turbo kit that should fit. It is $$ and exposes the turbo to harsh conditions while off-roading...which is ironic because they show a Tacoma climbing the side of a rock wall

My point is: If you wheel your rig and end up submerging the turbo, you are in for some trouble. Lag might also be an issue given its mounting point.

Anyway, here is the link.

Again, I know you asked about manifolds, but other than going custom, this is all I am aware of in the turbo dept for the 5VZ.

 

The turbo takes the place of the muffler. It's in the same position.

Everything on the undercarriage is in danger on the trail.

It's just seems more vulnerable because it costs 3 or 4 thousand dollars.

 

Im considering turbo'ing my runner to and was wondering about costs and options for a good custom job.

 

I would ask in the "performance" section on Customtacos.com, those guys have a bunch of turbo'd 2.7L's and might now where to get a set of manifolds for the 3.4L as well...

Otherwise order some mandrels from magnaflow, have some flanges laser-cut and weld a set up yourself. I think that's more or less what we are going to do for the cross-over on our 3.4L swap...

 

Thanks for the replies guys.
96 Runner, I read that thread about 1 week ago. Even though i dont go wheeling (yet), i dont think its a good idea to have a intake easily accessable to water. About the manifolds, thanks for corecting me on that. I've never paid close enough attention to my headers to know that there are two. This is a place of discussion and learning, your tip will greatly assist me in my project. I cant seem to visualize where to mount a turbo without seeing the turbo manifold. For my turbo, i totally want to customize it. Kits imo are a waste of money.
Sean, thanks for the reply. I'll browse around at customtacos in a bit. Your method sounds nice, but i dont have access to a welder. Any welding done I would have to bring to a local muffler shop.

 

That's what they say, but you can clearly tell from this picture that the turbo is mounted in front of the muffler - way in front. In fact, they must have moved the cat back or removed it. This picture is the turbo (look at that filter location! ) mounted right at the output shaft. Too much crap to break and too easy to suck in water if you ask me.

 

No problem. You may want to take a look at the 300ZX TT for reference (but it is twin turbo). I honestly do not see how you are going to fit custom manifolds in that tight of a space. And trust me, it is really tight. Quite honestly, you might be in Supra-swap territory by the time you get a custom turbo set up going. I am sure we are all interested, so keep us posted on your progress.

 

I know we have gone over the STS setup many times but every time I see it I can't help but notice how poorly designed it was for multiple reasons......turbo very inefficient due to the distance away from the heads, poorly placed intake, turbo easily damaged by water or debris from underneath, outlet to 3.4L intake has many obstructions and thus large losses as well....it is just a very poor setup overall. It was designed more for convienence of turbo placement by the designers and to keep costs down for the manufacturer because if you added a set of custom headers and a second turbo, the price would easily be in the $6K range for sure.

I am not saying not to try and go for a dual turbo setup but you are definately going to pay more than you would for a supercharger setup and you should also do as much research on turbo setups in other cars as you can so you know what you are getting into (as far as parts, time/labor, cost, efficiency, boost pressure, fuel injection, ignition setups, yada, yada).

 

One of my buddies in sporting clays had a 3rd gen turboed 3.4L...at the time i didnt know squat about turbos, but that thing was crazy fast. His was intercooled as well.

Ill ask him about it the next time i see him.

All I remember about it was that it had a turbo time and he had a manual fuel control setup...that was wierd.

 

You really should just do the swap. It isn't cost effective to turbo the 3.0 or 3.4. And if you do turbo one of those, you will beat your head on your dash when a supra powered 4runner dusts you.

 

My buddy just purchased a 350zx n/a. He was thinking about turboing it and that engine seems so cramed into that area. I can barely fit my hand anywhere let alone turbo.

Pics would be awesome. I clicked on most of the turbo 3.4l turbo threads and all of the pics are dead.

I'll probally do that as a last resort.

MTL_4runner: Im doing as much research as i can before jumping in blindly. I'll probally start this in a couple months if everything works out

 

Research is the key to having the project come out with a good result.
Here is a good link to where they did already do a 3.4L dual turbo setup:

Might want to email them of give em a call and see what was involved.

The cost on building a motor like that is out of this world. I know they did it but to build a motor like that one with 800rwhp is going to run you like 16k or somewhere in that range. They would have to totally rebuild your motor then start on the manifolds and other things like that. The 3.4 was never meant to produce that much power so its gonna take lots of $ to get it done right and have it be reliable.
