Planning on picking up either the dezod t.e.a. kit or the new kit from turbo toyotas in a month or two. my question is how much boost or hp can my motor handle with a bottom end build from say zpi or dezod? I planning on reaching between 350whp and 400whp and i know im going to have to upgrade to bigger injectors and a fuel pump.

 

Probably 10-12psi without more work.

 

uhh like 18+

 

oh sorry I missed the bottome end build part. lol.

 

I love these type of questions.....

1st off with the right fuel management, ie standalone you can do 350-400 on the stock motor Granted having a built motor offers peace of mind and will allow you to sleep better at night, but without the right fual management it doesn't make much of a difference.

2nd...how much psi you will have to run to get your desired whp will be based on the turbo you decide to use.

One turbo at 9spi(say a T3/T4) vs another turbo at 9psi(say GT3071R), you will get 2 different horespower figures as each turbo flows a different amout of cfm.

Hope that helps

^^^ what type of fuel management would you use to get 350 safley on a stock block

 

It(350) can be done with emanage, ultimate, unichip etc.

But its allot easier when you actually have full control.

Any standalone will work, AEM EMS, From what I have seen that Hydra system will work, and obviously Motec or Autronic. None are cheap, which for us is the downside.

A good EMS system is all we are missing, all the other components are there

zpi has their standalone fuel management out now. dezod has their aem system coming out soon too!

 

wow 350-400! I didn't think a standalone made that big of a difference.

Can you go a little in depth about how it helps out that much?

 

it doesn't make that huge of a difference on its own, but the stock ecu can only do so much and the same goes for a piggyback ecu. it is just alot harder to get the engine to behave the way you want it if you don't have a standalone engine management system.

 

Isn't ZPI system the Hydra unit? or do they actually have there own stuff? I am asking cause I don't know not to sir the pot.

And yes Dezod is making an EMS adapter, there are others that offer it too, but I am curious as too which EMS there adapter is for, the EVO unit or the Honda 1050 box??? Again just being nosy, it really doesn't matter much.

But these systems are what is needed to make "easy" power. When you don't have to fight the factory ecu, life gets so much easier.

Now all we need is for them to make an affordable option so it will appeal to the "masses"

zpi's is the hydra unit.

 

There is a lot of information with regards to the differences between a standalone and a piggyback system. This is a good article I found that might give some more insight!

It comes down to having full control over the timing and fuel.

With a piggyback unit you are fighting the factory ecu and you have only so much control. Wether it be how much fuel you can add/take away, same with timing.

When tuning a piggyback its a law of averages. You can add fuel etc, make 3-4 passes and there will be differences in each one. Duplicating the exact same thing over and over again is tough. You just tune it to a safe range and go from there.

Piggybacks provide an argument for the factory ecu, you always try to win but not 100% of the time, so you can never be 100% sure in what is going to happen.

Where as a full stand alone unit you have full control and can basically push the limits without having to worry about if the factory ecu is going to fight you or not. There is no argument.

Tried to keep it simple.

finially, somebody who can speak our language!



thanks todd!

 

Do the Hydra and AEM is hand in hand or does one have a better apeal to the tC?

 

Neither are application specific, which isn't that big of a deal.

But both will get the job done

Todd, great information. Just to reiterate what Todd said, standalone gives you 100% control over ignition timing, cam setup, EVERYTHING and it gives you a 100% CLEAN SLATE to operate on (to customize as you please) without any confrontations and limtations a piggyback would cause because it still has to deal with the stock ECU.

 

would you be able to make alot more power on a turbo'ed car with a stand alone than you would with a piggyback?

 

alot more is relevant to the setup, but yes you can make more power.
