When i get my xB i am going to want to get a turbo... well maybe... I just want to know how much a good one might cost and how much hp increase it will give me and if it will help/hurt my mpg

A lot depends on how much you want to get out of it, how much boost you plan on running, etc.

Remember the hidden costs of turbocharging, such as replacement parts if/when anything breaks, the need for premium gas (esp on xB's 10.5:1 cr engine), switching to synthetics (usually recommended for turbo motors), and so on.

If you have lots of cash, time, and knowledge; go for it, but be sure you have a backup ride.

 

wow i didnt know that i would have to get the expesive gas if i would get a turbo... and no i dont have the money but i do have the time

 

well, the guy that does fab. work for me is doing one for the xB for around $3500 for a friend. This includes intercooler, charge pipes, turbo, custom manifold, wastegate and the misc. parts to make it work like fittings and clamps. If done right it can turn out really good and it would be awesome to see some turbo boxes on the site.

 

Sounds like you need to do your homework bro'...

 

You can use 89 or 92. Depends on if you upgrade your fuel system and what management system you use. You can run a conservative tune or mild tune with a good management and use 89 octane. It is a little better to use 92 due to the fact that it will burn better.

 

You cant use 89 on these motors w/out any minor detonation. You can do all the fuel upgrades in the world and it really doesnt matter what kind of management system you use...I still wouldnt advise it.

 

well research is the best thing for any car you wanna tune.

look at other peoples set ups and what not, then go from there.

Turbo charging can be expensive if you dont know what your doing. research research research. run a search on turbo by clicking on search and typing in xB turbo or similar keywords. i havent seen any complete build ups, such as pistons, cams, sleeving, polishing and porting, fuel pump, and lines, injectors, intercooler plumbing, cuting and welding, etc, etc.

Sorry if this sounds intimidating but dont go buy a turbo and throw in 15LBS of boost unless you know what your doing. Were here to help at scionlife!

Theres been a few of them running around
$3500 aint too bad but whats the guy gonna do about fuel delivery/tuning??

 

for fuel delivery, what about the fuel pump included with teh PE blower? is thatsufficent enough?

 

Naa...has nothing to do w/ the fuel pump because the in tank regulator will only allow you to flow up to 50 psi w/out modification to it. I had a 255 LPH Walbro to test this out and it still only flowed about 50 psi under boost...I believe that PE sends a replacement regulator or some sort of setup that eliminates the in tank regulator. Converting to a return line will only get you soo far as I have learned and I feel that the injectors did nothing but make me run rich at idle and low RPM's when not under boost.

 

Haven't really discussed fuel system yet. Probably will go with a greddy e-manage or Autronic SM2. Will probably go with upgraded fuel pump, ss lines, inline fuel pump, better flowing injectors....all the basics. Not looking to push huge boost. Just between 8 to 10 psi for daily use.

I will make sure pics and dyno sheets are posted as soon as it is finished.

 

I did all that already...it dont make a diff. Its a waste of time IMO. Even w/ those upgrades I very rarely turned the boost up to 8 psi. Try intergrating a Injector interface w/ 2 additional injectors and place the unit between the throttle body and the I/C.

 

Sorry if im wrong, but this sounds like you have no idea what you would be getting yourself into. Converting a n/a motor to f/i is very high maintenance and expensive. In most cases its worth it, i'd say its worth turbocharging the 1nz-fe. It boils down to a great deal of things when you talk about cost. Manufacture, boost levels, how envolved the turbo set up is, hidden cost with fuel delivery, so on. To get the most out of the turbo you would want to run a turbo-directed (specific to turbo if you will) exhaust. They don't run too cheap for a decent one. Also, long term maintenance can be costly if it isn't tuned correctly and taken care of. As far as gas, the best thing for you to run is 91-95. (depending on where you are and how much boost you are actually running) Lets just say premium.

At any rate, the best advice i can give you is learn how a turbo is made, what it does exactly, how its pieced together, what you need to run properly, cost, calculate rough costs in time for install, tuning, dyno time, so on. Basically, add roughly $600-$1,000 on top of the turbo kit itselft right away for tuning and so on.

Know exactly what you are doing before you go the f/i route. Not trying to scare you, but you need to be prepared incase things go wrong, or whatever. Better safe than sorry.

I know a few honda guys who did the 5th injector thing and had great results. On my Conquest there is a primary and secondary injector. The secondary kicks in under boost for more fuel. Which is similar as the 5th injector. Autronic can control a 5th injector. Not sure if the e-manage can.

 

hey killerx, he should read the book on Basic Turbocharging. Its a good info book and gives you an idea of all thats involved.

 

Read Maximum Boost by Corky Bell front to back....then go and re read it again and then finally you are ready to turbocharge an n/a motor

 

sounds like i am getting myself into a lot of trouble with wanting a turbo... think i might just stick with the basics... thx
