Need Info: True dual exhaust and turbo 3VZ-FE

[camry6]

Hey there, I don't know much about turboing an engine in regards of the technical changes that I will HAVE TO DO to get it to work decent , I know what a turbo does and how the system works . I do know how to phisically pipe it up and install all of the components .

#1. I am wondering how much "turbo" I can run on my stock engine management before I need to get into piggy backs, bigger injectors, fuel regulator, $$$$ etc... I am not looking for crazy power, just a little more edge for everyday driving .

#2. Are the hybrid turbos I am seeing on eBay worth buying ? I know that Garrett is what I should be looking at , but it will be a BUDGET project . (Yes, I do know about the Tuners Tri-angle ) I can do all of my own fabrication and install. Have anyone here used these eBay turbos before?

#3. Has anyone ever known the gains of true dual exhaust on the 3VZ-FE engine. (By true dual I mean 3 cylinders on each pipe x 2, with crossover. NOT dual catback). I have a 2 inlet-2 outlet Magnaflow with built-in crossover. I am planning on removing the catalytic converter and resonator, and going with two straight pipes using the 2 in-2out Magnaflow muffler .

#4. Can you suggest an entry level turbo combination ie: Exhaust wheel and compressor wheel trims to work best and other suggestions to get my 3VZ-FE up around 225-250 Horse power. Any input is appreciated, Thanks!

1. any turbo you install will require some sort of tuning. this is a good thing since you have obdI which is great for tuning.

2. in most cases, ebay turbos are liek a macco paint job, look good for a while but will ware out quickly. thats one of the areas you dont want to cheap out. getting something like a factory spec ct26 would even be better. you can however use component kits found on ebay and they are jsut fine.

3. unless your going to twin turbo then a true dual would not work. no tto mention the gains wouldnt be really worht all the work. a large Ypipe into a 3" exhaust would me more then enough for sub 300hp goals. if you want more info on it check out solaraguy.com. a member did that on his lara.

4. cant help much there, im a turbo noob too...but ive used this when i wanted info...

im sure someone will chime in with more useful information.

this is a project that i'm working on in the long term.

first of all, u will need a good piggy back to tune the car if you go turbo.
i bought myself an Greddy E-manage Ultimate, so it'll suffice

2nd, DO NOT ever ever buy turbo from Ebay. too many knockoffs, too many defective products that u won't be able to know until you install and run into problems.

try ATPturbo.com, they are a reputable garrett turbo seller and their price is more than fair.

since i've been doing a lot of turbo searching, the best budget turbo would be the T3/T04E hybrid turbo in 57 trim and an compressor AR of .82.

this is a good size turbo to crank out 300whp, given that tuning is done well. theres no point in turboing the car if you only want 250whp. it's not worth it because you can easily acheive 250 with TRD supercharger.

as for the exhaust. I have a full custom from Y-pipe to muffler. I recommend at least one large resonator because straight pipe 3VZ on a magnaflow is very very loud. I'm in process of throwing in two Vibrant resonators in my car.

hope u find this helpful

Something like this, then?

TRD S/C will need a adapter plate to fit, and i'd push for factory turbo (ct26 or if you wanna get crazy ct-12a/b's) over the T04

[EEngineer]

^fitting a small CT26 on the 3vz is a very bad idea...it will destroy the turbo cuz it'll spool at max all the time.

the adapter is for IAC and that can be custom fitted with someone with knowledge.
adapter plate is too expensive to buy from woodsport

i figure if its good enough for the supra, it should do equally as well on the 3vz. its not like much in the way of power or displacement has is different between the 3vz and the 7m. but im no expert on turbos.

[EEngineer]

well, based on the different characteristics of the 3vz...
the 3vz generates much more flow at lower rpm than 7m.
a ct26 operates at 10 psi as max for the stock setup..which is reliable...the 3vz would be able to spool that so quickly....it would wear out the turbo much faster

[camry6]

Any more opinions on my post?

[oopssorryy]

I know I'm reviving an old thread but about the CT-26. Could you run it at 7-8 psi on the 3vz-fe without damaging it? I want to run just a real mild boost and was wondering if this could be a good option. It's the only solid turbo for 500 bucks, and I'm hoping with some port and polish, and cutting out the cat, I could get it up to 230-250hp.

[Tony the Tiger]

CT26 off the 7M-GTE will work just fine at 7-8 PSI on a 3VZ... The difficult part is to find the proper inlet and downpipe flanges, and also make the oil feed and oil drain connections work on the CT26. Externally, the CT26 is quite bulky.

The CT26 on the MR2 has a much smaller turbine housing and a divided scroll housing... Don't use that, like what EEng mentioned, it will be too small for a 3VZ.

Okay Thanks! My dad is a fabricator and a mechanic, as is my brother in law. I figured I would clear it with the people who really know their stuff. One more question, everything I have been seeing says that you can turbo the 3VZ without changing any of the internals. Is this true?

Yep! Stock internals are good to 350whp. Upgrade to forged pistons and you're good to 450whp. You might want to look in better head gaskets though. The 3VZ has a bit of an issue with those.

[1BADBAJA]

Sorry about bringing up a old post.

What head gaskets will work with the 3vzfe and some extra boost?
Factory?
1mz?
Copper are more expensive and more expensive to machine the block and heads for as well. Plus then you have to use coatings and hope for no leaks. Yikes
