oh no, im guessing 203whp on the stock motor...

His built one I guess will have 325whp

^ I think the question is how much she'll make with the stock motor, before the swap.

I tell you what, after the initial tune, when we swap motors, I WILL run a poll with a prize for the final number on the built motor.

Hey garm I am still not understanding why you upgraded the throttle body and intake mainfold to that of the xB?

cali yaris · 04-04-2009, 09:50 PM

The xB is a cable throttle, the Yaris is drive by wire (electronic throttle). To use the AEM standalone management effectively, we needed to change the throttle to cable.

Plus, I really LIKE throttle by cable, super responsive and tunable.

Is the throttle body diameter of the XB equal to that of the yaris? Is there any other differences in between and why the XB is cable throttle and the yaris by wire, is there any purpose?

Here is what I know about cable throttle bodies vs drive by wire systems:

Cable throttle:
-Very responsive and has been used for many decades.
-Connected to the gas peddle by a series of pulleys.

Drive by wire:
-Smooth acceleration.
-There is also noticeable lag when you press on the gas peddle because the computer has to tell the ECU how much the throttle has to open; not as quick as good 'ole cable throttle.
-Take a look at the gas peddle on a Yaris. Notice anything? There is a box to which a peddle sits in, connected to some electronics which lead to the ECU.
-When you drive over some speed bumps and you press on the gas peddle a little bit, the car wouldn't jerk or move violently in the event of sudden acceleration. This is meant for driving comfort.

THanks for your reply it is something that I didn't consider.

So if I consider to upgrade to cable throttle what parts exactly I need and how can I know if the ecu supports this feature?

cali yaris · 04-05-2009, 11:36 AM

what ECU do you mean? The stock ECU will not handle DBC

eTiMaGo · 04-05-2009, 12:44 PM

Parmas, are you sure you don't already have a cable throttle? As far as I know the echos/first gen yaris didn't have drive by wire yet...

This is what I have -- Walbro in-tank 255:

What is your Walbro's flow rated at?

Nevermind. I just saw...255 lph.

cali yaris · 04-06-2009, 11:32 AM

UPDATES 4/6:

The GT28 turbo is installed, replacing the GT25. The AEM a/f gauge is wired.

Just some piping and then modding the AEM box for vvt-i and we are ready to fire it up.

m911gt · 04-06-2009, 11:38 AM

Excellent, best of luck Garm!

LtNoogie · 04-06-2009, 11:40 AM

Garm, did you size your fuel pump based on the HP you expected to output or did you just select the largest one they offered of that type?

You already have the throttle by cable!!!

That is the largest that Walbro makes. IIRC, there are many Bosch pumps that flow enough fuel for much more stupid amounts of power, but they are much wider and will not fit the spot in the stock tank (picture is back a couple pages). Plus their low pressure performance is crap.

In any case, the Walbro 255lph pump is still capable of flowing TONS of fuel, in fact for over 500 whp. There are other constraints such as the filter, lines, rail, etc that limit it.

cali yaris · 04-06-2009, 02:22 PM

^ can't add to that, great answer.

The Walbro 255 is pretty much the standard pump that everybody uses and capable of supporting lots of power.

Is good quality and cheap...

There are not that many options in regards to flow capacity....

If you are making anything from 100 hp to 500 hp a Walbro 255 will work for you. You don't really need to match the pumps preassure capacity to your fuel needs. That is the job of the FPR.

You only need to worry to have a pump that will supply enough fuel... and since a Yaris will never push 500hp and walbro is all you ever going to need...
