Well, I've been trying to dig up information from every possible place I could find it. I've gone through hundreds of threads on TN in the last few weeks and months. I've talked to tony just a little gettting some basic info on the topic as well.

After reading more about the many options for boosting I decided to definetly go the custom route... Keeping it slow but very reliable. Like most others the camry is my daily driver.

Honestly at this point im not concerned about how much gain im getting and how fast it will be, i'm more into the process and actually getting it to work the way it should without any minor or major setbacks.

A lot of the work I have done on my car is the result of months of research, reading and learning and I want this project to be a part of that. I enjoy working on my car and I'd much rather undertake this myself than pay a shop to do it.

With that said. As far as reading and learning where else can I look for more details on this? I've read and re-read many threads on this and kept notes and copies of the threads aside with good bits of info. I've been on wikipedia trying to learn the basics of the engine in general and learning about the parts that make up a turbo... What they do and how they work.

I know money was something discussed as well, as far as I'm concerend its not an issue since most of the work will be done by myself and yes I do plan to learn to weld before doing this. Of course its not an overnight thing I will be doing lots of practice before making any part.

I wont be starting this project anytime soon but I would like to continue gthering info but this time from people who have already tackled this project and can provide me with much more details and maybe even pictures.

If I've overlooked anything or missed steps in the learning process please do let me know.

Hmmm good luck. This is something probably all of us V6 owners have sat around and thought about. First of all you pretty much have to rebuild the engine. With six cylinders it's going to cost quite a bit of money for the parts and I highly doubt you'll be able to do it on your own. I'm not trying to say what you're capable of or not capable of, but engine work takes a lot of previous experience to do. I would absolutely love to do a custom turbo setup, but it would take so much money to do a good, quality job on it (i.e.- Tony's Camry).

I guess it all really comes down to how much power you want to get out of it. If I did a custom turbo setup which I have thought about a lot, I would keep the engine internals stock and use a smaller turbo. I would aim for 250 reliable wheel horsepower. It would be such a pain in the ass to get a turbo manifold all rigged up and to get it tuned, but other than that it wouldn't be too difficult to do it.

What are your plans for it? What are you trying to achieve and what do you plan on using? I definately wouldn't want to do it without help from a shop.

As stated above I plan to go for a small turbo which will allow me to keep everything on the engine as stock as possible. Again I'm not out for massive amounts of power, Just enough for some kicks. I want something reliable.

My uncle is actually a very good mechanic and my cousin knows a fair bit about engines and tranmissions so that wont be a problem at all.

Since last year I was actually tossing this idea around in my head and I had put it out because after only a little reading I found that it would cost way to much.

But after some research and finding out that a small turbo can be done and be safe I decided this would be something good to fool around with.

As long as you can weld you could probably set up a small reliable turbo for 2 grand. Just use something small like a t28 or something and up the fuel pressure. Better plugs and wires, an intercooler and some way to tune the fuel and you would be set. The hardest part would be mounting the turbo and piping. Just a small simple turbo will easily get you to 250-260hp.

Yea thats exactly the plan. The safe and reliable setup was actually what Tony and I talked about a while back.

if you're really serious on doing this then you can build a reversed Y-pipe that connect the two manifold but points them towards the front of the car and up to where you would put the turbo.

instead of T28...go for a T3 instead..the T28 is just way way too small. you can always control boost level with the use of a good wastegate or even running an internal wastergate.

with such low boost levels you can probably get away with not using an IC (intercooler)..so run the hot gases back down and out to the cat and the cold side to the engine.

it will be safer to run higher flow injectors and higher flow fuel pump. i'm not sure what's the rating on the stock injectors.

a stand alone or piggy back fuel management is always nice with the extra boost.

if you need any parts for turboing, i have a ct26 and 440cc injectors as well as a few other things that might put you on the right path.

I would be very interested. Could you PM the info as well as prices? Thanks!

The t28 was just a generic turbo that would work, there are obviously better suited ones for the task. And i would always use an intercooler since it makes it easier to tune for safety, important on the 1mz. The injectors are rated close to 250hp or thereabout and the pump is good for 300. All these can be upgraded for safety, but a simple cheap turbo doesn't neccasarily need them.

The CT26 seems to be the best way for me to start anyway. I can always upgrade later on.

CT26's are complete blah.
Which means buy a plasma cutter, or an oxy-fuel torch for your flanges. oil, coolant, turbine inlet & exit. Even at that, it's roughly the raw flow rate of a T3 60/82 (A small hair above the common 60/63).
Why, on Earth, anyone would choose that turbo is beyond me. Which is why I sold mine. Absolutely no reason for that entire family of turbo's to exist in the second hand aftermarket.
I'm ranting. Anyways... Skip that POS.


Pick your peak power, and powerband goals.

I would highly suggest that if you don't plan anything more than an aux. cooler, fluid change & valve body upgrade for the automatic transmission. Daily drive 280hp & don't exceed 320hp.


That would lock you into a t3/t4 hybrid class turbo. A large t3 could easily enough stretch up there, but you might wanna take the t3/t4 for future use.


A T25/28, or small T3 would be more of a low end torque monstor build. Basically... You'll add alot of responce, but it will not make descent numbers passed the midrange. Which is extremely unsettling. Especially since there is plenty of exhaust flow to severly over-accellerate the turbine.









Plan on water injection, you'll want 369-390cc'ish injectors to begin with. 330's would get there with pressure, but the slightly larger ones will have an easier time. Especially if it's a used set - as they'll be more than enough.






























Curry what do you actually want to know? Nothing about it is particularly complicated. It's simply taking & understanding thigns one step at a time - it's just that you take the steps en-mass. Set a budget too.

Yes I was waiting for toys to shed some light on this.

If you say its blah then its blah. I will go with a T3 setup.

Well as far as wanting to know, I now have an idea as to how the entire system works so thats a start.

I'm basically just trying to figure out exactly what parts I need, the best spots to find them for decent prices.

I need to know what a normal part would go for so i can pick deals and set my budget as you mentioned above.

Basically a parts list of everything I need.

From what I have read and talked to Rdizzle and Tony about I need the following:

Turbo
Intercooler
Oilcooler
BOV
SMT6 (read about on a site of yours)
Wastegate
Fuel Regulator
Turbo timer
and of course guages.

Basically I understand enough to this point where I just need an exact parts list with part numbers and what not to get going.



I wont be the only one doing this. My cousins friends will be doing a great deal helping me out with this. One of them is very knowledgeable about turbos and performance. Another is a very skilled welder (saved me the trouble of learning on my own) and the other two are beer specialist =P


So the project can get started as soon as I finish my research and part gathering...

Several things I have to address... Small turbos that chokes the motor would only add low RPM "boost" response, but not throttle response. In fact, small turbos will always give you that spongy throttle feel whenever the engine is not in boost. Just making sure that people won't think about getting really small turbos to improve engine response. You'll only get low-end and midrange torque and quicker power delivery with small fast spooling turbos, but the motor will lack the "lightness" of say a good breathing NA motor. On the other hand, a really large turbo sometimes will add lightliness to the motor because of the great free flow before the turbo begins to spool.

Anyway, for larger motors matching with small turbos, you can always step up to a larger turbine housing. You'd be surprised that a small GT2860RS for example which falls into the T2 frame family can still breathe faily well for a 3.0L. The turbine flow maps for the 0.86 a/r T2 housing can easily support the flow, but a common thing to do is upgrade to an ATP T3 drop-in housing and that turbo would work really well with the 1MZ. I can't even stop imagining the insane spool AND response if I slap on a GT28RS with a 0.82 a/r turbine housing... It's basically instant spool starting off 1800RPm probably and probably enough flow to hold torque all the way to redline if not surpassing the compress flow rating (kept under 300 WHP). Hahaha, that shit would be insanity. (Hint: I might be running two of them :naughty:)

yea it would. id rather do that than the t3/t4 hybrid setup i was going to go with. but i probably wont be going with it at all now that luis is a no show. damnit tony i wish i had just given you all the money i gave him and had YOU do my turbo setup!! :hammer:

So your saying in the end the smaller turbo wouldn't be all that great but if I go with the T3 or use a GT28RS with a 0.82 a/r turbine housing... that would provide me with the safe/reliable setup?
