Just a conjecture- I think the USDM production kits will come with the "blue-boxes" just like the Honda kits. The blue boxes are basically just like E-Manage, except they cannot be reprogrammed.

I'm curious as to how this kit can get by without larger injectors or larger fuel pump though. EManage can do a little bt, but it cannt get around those basic limitations.

 

I'm sure that the injectors and fuel pump upgrades will be suggested when you buy the kit. But like others have said, it would drive the price up. The E-manage is a good computer, but I think that showpaojoe hit the nail on the head about why it wouldn't be "optimal."

Back on topic though, that turbo kit is really nice! And for $2100.00 it's a steal! Best of luck in selling it bro. Sorry to hear about your car.

I just answered that question. Upgrades refers to doing the fuel system as well...and when you choose to upgrade the fuel injectors and fuel pump...then you still have the E-manage to fall back on and retune...unlike a black box setup which someone has already mentioned as being un-reprogramable.

And this kit doesn't need them because they made it as an efficient setup as possible...they aren't gunna recommend going past 5psi or so. Shiii, you don't even need a black box to hook up a turbo to your car if your gunna run 4psi so stock engine will handle this _____ output no prob.

 

Yeh you don't need fuel upgrades to run 5-8psi of boost, the stock fuel system is adequate. As far as the US kit they are putting out soon, you will get the "mini-emanage" as they call it which is a little black box that is pre-tuned for the kit and cannot be reporgrammed. Yes the US kit will be better for those who dont have a dyno or have access to a tuner. If you work at a reputable shop, then I know you guys dont just slap turbo kits on cars without any tuning.

If you have access to a shop or a dyno then this kit will work great because with E-manage you can fine tune the turbo setup now, and if you upgrade your engine internals in the future you can retune the e-manage to justify more boost.(With the US Spec Kit you will have to purchase E-manage to tune engine).

 

so will this kit be carb legal? i so so so hope it is.

 

theres not much more tuning to be done the motor cannot handle much more with stock internals. and aftermarket internals arent readily available yet.

 

I meant that if you upgrade the motor later on you can retune the emanage for more boost. If you had the US kit and you wanted to upgrade you would have to purchase a e-manage or some type of piggy back. The JDM kit comes with the Emanage so when you do upgrade you can just retune the emanage.

 

So, has anyone here even tried to turbo an xB? I doubt you guys have, all of you are talking from some rumor you've heard. I'd just like to say, that I have a full e-manage system setup in my xB. I also run a completely re fabbed TSI turbo kit, I run 310cc injectors from a 2zz-ge and a 2.5" manifold back w/ magnaflow cat and muffler.

I have first hand experience with the tuning of the xB and boosting the xB. Saying that the motor can take boost without management is false, it will start falling flat with only a couple pounds of boost, it will lean out and stumble. You need management. You can get away with stock injectors, but they're rated around 200cc, which is far from optimal. You need something to increase the duty cycle of the stock injectors, though. E-manage with the injector harness is perfect for this, since it adds to the pulse width instead of forcing the MAF readings to be higher.

Anyhow, have fun boosting and if anyone needs some guidance and really want's some answers to some questions, ask me.

8psi daily, and no internal problems, no detonation, nothing. 10psi on a stock motor is feasable, even.

I'll let you know when I'm running 10lbs... by way of video.

 

Damn 200cc injectors at 8 pounds, your max duty cycle there. Deffinately 310cc would be good for up to 10 lbs.

When you say a re-fabded TSI kit which kit is that? You runnin a 14b turbo? Or have you gone with something bigger? I have heard of some people also adding a 5th injector, is this true? Do people have to do this without a tuning device like e-manage?

Also how do you compensate for the xB being a Returnless fuel system? I remember boosting Hondas with a returnless fuel system sucked.

 

It means he bought the TSI kit for the scion but it was garbage to begin with...so he had to re-fab ____ around to get it operating correctly. TSI stands for Turbo Specialties Inc.

Damn J...been awhile man. These cats need some schooling on scion engines and swaps like mad crazy. And I'm one of the few that answers your first question with a yes...but have gone far beyond that.

I got a new toy for you man...save up $3200 and it'll bump you upto 220whp at 6psi.

 

I too have experience with a turbocharged Scion. You definately need the fuel system reworked if you want to build more than i think it was 3.5psi. My turbo kit is almost the same as Agginmotorsports friend which he didn't have a fuel system upgrade but have it running at 3.5-4psi. It worked but not a lot of power. So fuel management is definately required for higher boost applications. I have ran at 12psi for a couple dyno runs but didn't get the dyno sheet. I have driven my car on 10psi and it felt pretty damn good, but i stick to 7psi because i feel it is all around the best setting.

 

4 hours left in the auction for anyone who is still interested, I need to ship this kit out, I need a new car...I guarentee it is compatible with the US XB or I will give a full refund. Bid away...
