yaris ts 1.5 turbo

[Paris vvt-i]

Hello my friends!!
I have a yaris ts 1.5 2004. I am looking forward to turbocharge it!

My 1nz fe has the following and only changed components:

1) CP pistons 9:1 75mm (stock bore)

2) Crower rods and better rod bearings

3) stiffer valves and valve springs

4) toga engine bearings



soon i will get a walbro 255L/h fuel pump and larger injectors.
For ECU I will install a standalone Link g4 storm.
The turbo I chose is the Garret2554R. When I put the turbo I will also put denso iridium spark plugs.

My goal is to achieve maximum 230hp at the crank reliably.

As for the injectors I will get 370cc or 440cc . which of the two would you choose?

[Paris vvt-i]

Anyone?????

[cali yaris]

larger injectors for that power, you'll need them.

probably need a return line too. what turbo are you going to use?

[Paris vvt-i]

Thank you. I will use the GARRET 2554R!

[cali yaris]

230 bhp is about 210 whp, you should be fine with the GT2554R. Good luck with the project, that will be a very fast car.

+1 with what garm said, go with the 440cc injectors just in case you're planning to upgrade your turbo in the future.

you can also check out this 1nz-fe here (http://www.viosturbo.com/2010/08/gt-auto-stage-1-special-turbo-kit.html), the car made 200 whp using the GT2554R on automatic transmission with a meth kit and standalone ecu.

by the way, hi garm long time no see! :)

[slothman86]

Yeah, nice idea. I've been contemplating on boosting my Yaris for a Loooooong time, I would like to follow you on this one, but funds wont allow it just yet.

[Paris vvt-i]

Thank you all of you! but this 1nzfe made 200whp with a completely stock motor????? I thought Garm had the max safe hp on a stock 1nzfe (182whp)??

[cali yaris]

No one knows exactly how much power you can push vs. how long the motor will last.

[cali yaris]

Well. someone figure it out the hard way. Please. LOL

[cali yaris]

^ I mean someone go beat up on a stock motor until it gives up, so we can all learn. :biggrin:

[Paris vvt-i]

I am also thinking of changing the transmission to one of a 2nz fe which has longer gear ratios

[changchewsoon]

No one knows exactly how much power you can push vs. how long the motor will last.

double agree on that, hopefully someone can whack the motor until it dies then we all can learn hahahaha....:D

though this guy here (http://www.viosturbo.com/2010/09/gt-auto-special-tuning-package.html) has been pushing the stock 1nzfe motor with his turbo kit for more than 3 years, and is an often guest at the local track circuit.

[Paris vvt-i]

240 whp?? on a stock motor????:eek:. by the way what exactly is that water/methanol kit?

[Paris vvt-i]

do you think that stock 2nzfe transmission will withstand 230hp?

[Paris vvt-i]

We have almost done with the exhaust and intercooler! photos soon:smile:

[FunForDummies]

Looking forward to your next post... :drool:

[Bluevitz-rs]

don't worry about the transmission, it'll hold the power.

[Paris vvt-i]

:headbang:

we pretty much have the same setup, i have the t2560r instead t2554r and i plan to reach 200whp once tuned and get larger injectors too,,, do you know what injectors fit the 1nz fuel rail? (i have a perrin fuel rail) i mean,,, what injectors largers than 1zz can fit

[Bluevitz-rs]

I think I read 2AZ injectors fit

[cali yaris]

^ yes, and 1ZZ, and you can order any injector size you want from RC, etc to fit the 1NZ

I'm running 632cc injectors, I don't think I can max them out with this motor.

[Paris vvt-i]

I will use denso 440cc injectors

[Toy Box Racing Store]

What valves and springs are you running?

[scioncrew]

^ yes, and 1ZZ, and you can order any injector size you want from RC, etc to fit the 1NZ

I'm running 632cc injectors, I don't think I can max them out with this motor.

yes you can with GT30R and 30+ boost :thumbup:

[Paris vvt-i]

I am running yaris cup valves and springs. I am planning to raise a little bit the rev limiter:smile:

[Paris vvt-i]

update! the car is finally tuned and running very good! this is at 0,9 bar of boost :smile:

AWESOME, nice job!!

[pimp my yaris]

I am running 2azfe injectors from a 08' scion TC. The 1zz maxed out quick. They are not much larger then the 1nz injectors.
