kit?

[Scubaru Steve]

anyone see this kit in person or even running it?
im a big fan of the top mounted turbo, and thinking this may be the next step for us. gt25 probably. flow more than the tiny tiny greddy, mayby a 28rs but dont know if thats gonna be to big.

whatcha think?

I run a GT28, and you give up quite a bit of low end power -- takes a lot longer to spool than a GT25, even with the smaller A/R choice. At least 600-1000 rpm.

I would run a GT25 to 200 whp or so.

[Yoda]

^^^This i am at 210 whp @ 10 psi. If you gonna build your engine up then go bigger.

[TURBO YARIS]

The OBX parts are designed for an xB. It will not fit correctly on a Yaris with modifications. And the more I look @ it I think you will have an issue of the turbo hitting the block. Notice that the flange the turbo bolts on to it is in an angle.

what a/r are you running? where does boost come on? does it fall off up at higer revs?

i understand its for an xb, i have the greddy turbo kit for the xb, both this and my kit the turbo sits up top (top mount) by the valve cover not the block.

[Crackerballer]

Yea and OBX stuff used to be TERRIBLE, they sold everything through ebay back in the day and it was garbage. I am not sure if their quality is improved or not, but I wouldn't risk it.

Just realized that it is a top mount. That even less likely to fit. The Yaris has less space than an xB. A part of the Yaris's engine is under the cowl. An xB doesnt have that issue. Also I know for a fact that the down pipe wont work. When I first made a mock up of my turbokit it was top mount, trust me when I tell you, its not going to work.

i too agree that the engine bay in a yaris is tight. but this is an echo and the engine bay is close to the size of an xb if not the same, the greddy turbo dp fit with no issues at all, why would this be that much different?

we have alot of space to work with, and if the wiper tray needs to be trimmed im sure we an figure that out.

[cali yaris]

the cb and echo motors are mounted closer to the radiator than the yaris, I think this is the point about how much of it sits under the cowl in back.

Only one way to settle it, right? Buy it.

[raja_kerbau]

can i get suggest, where is best turbocharger for use in 1NZ-FE with quicker spooling maybe in 2500 rpm, and journal bearing or ball bearing type?

i have choice brand garret GT1548 - 466755-3 or GT2554R - 471171-3?

because i not have a downpipe and exhaust manifold to.


i confused....:frown:

maybe i want to make custom turbo....

[Yoda]

get the zage kit

[raja_kerbau]

I am not sure with Zage kit long life.... for that's reason i trust to make it custom...

[cali yaris]

You want the 2554R. We sell a good mani, you can make a down pipe.

[raja_kerbau]

when 2554R start spooling can start from 2500? and do you have downpipe to?

[Scubaru Steve]

so the kit arrived, and all i have to say is i am impressed with the quality. it seems to be very good quality.

now to find a gt2554r at a reasonable price. trying to stay away from the ebay brand turbo's, but i guess we will see whats out there.

[Bluevitz-rs]

have you considered one of newer style variable vane turbos, or do they need fancy computer control to work?

What company is making them now?

[Bluevitz-rs]

I know Honda has one on their RDX SUV. And I'm sure ford is using them on the Eco-boost engines.

[TURBO YARIS]

I know Honda has one on their RDX SUV. And I'm sure ford is using them on the Eco-boost engines.

You cant use a turbo for 2.4 (RDX) on a 1.5. And the eco boost motors use Garrett gt15's on the V6, Borg Warner K03 for the 2.0 & the Borg Warner KP39 for the 1.6. None are variable.

And even if the were variable those turbo would cost a fortune & the flanges would have to be custom made.

[Scubaru Steve]

garret makes the vv turbos. very expensive and way to large for our application. very cool. and they have been around for a long time.

[Bluevitz-rs]

any progress in finding a turbo to go with the new manifold?

[Scubaru Steve]

no, all the ebay turbos have the wrong downpipe flange.

our greddy turbo kit is for sale though!

What kind of turbo is the OBX turbo?

[Scubaru Steve]

garret t2 flanged turbo.

perfect turbo would be the gt2554. new are 1000.

[Scubaru Steve]

long time since post, but i found a source fora genuine Garrett Gt2554 journal bearing. $100 used but in great shape. and if it blows up... i go get another for $100 lol.
so now to order a 3psi actuator, clock the turbo, find a way to mount the actuator, ceramic coat the exhaust pieces.

its so nice to have this turbo project back on track, not excited to but a stand alone though :( need to find a good stand alone for cheep that will work along side the factory ecu.

[cali yaris]

Great find on the Garrett.

Standalones don't work "along with" the factory ECU -- they work instead of.

[1.5]

Nice find on that gt2554

[Scubaru Steve]

Great find on the Garrett.

Standalones don't work "along with" the factory ECU -- they work instead of.

as long ad they completely control the air fuel and spark you can use the factory ecu to control all the other non horsepower stuff like an auto transmission and other bits. so they do work "along with".

no such thing as a cheap stand-alone. (ECU)

You get what you pay for.

Not sure why anyone would look for the cheapest stuff to build horsepower with. It's a time bomb waiting to happen. Building cars isn't for someone that needs to cut corners. In the end you pay the price for not going down the right path.

so your saying don't buy used parts? dont look for deals? my garret was a waste of money? a Haltec sprint 500 on sale or used is a time bomb? im no newb to modding cars. thanks for your input...

You are talking about a Piggyback like the FIC and eManage, etc. Garm is correct...a standalone is a full replacement of the ECU and if not mistaken the ECM in some or all cases?

[cali yaris]

If the management is fooling the ECU (sensors still hooked up to ECU; management intercepting signals and modifying them) and controlling fuel, spark and sometimes timing, that is a piggyback. If sensors are wired directly to the management, completely bypassing the factory ECU, that would be standalone.

This is my understanding of the words; I don't think anyone is right or wrong here.

And hell yeah, I would buy used parts if I knew where they came from and who was selling them.

Not a piggy back a stand alone, stock ecu cannot be fooled, we have tried and aem is even stumped. All fuel air and spark sensors are hooked up and have complete control, but stock ecu stays in place to help with all other bits like trans shift points. Do some reading and it will come clear. 1.5 knows, as he put it using a standalone "inline".

[cali yaris]

aem is even stumped.

I've experienced that before! :frown:

[1.5]

I thought people were having success with the fic piggyback

[why?]

I just don't know why you'd want to do that with an Echo, what is there to control that a standalone couldn't handle?

That type of thing is usually done for more expensive vehicles.

[Scubaru Steve]

Thanks for the settings! Now just need to find one on sale.

[Scubaru Steve]

well, finally clocked the turbo and fitted it to the manifold. need to make a custom waste gate bracket and the fit to the car. this turbo is easily larger than the Greddy setup. here some pics! everything will be ceramic coated black, the compressor housing will be pink to keep the theme of the ladys car.

[Bluevitz-rs]

thread revival... how are things working out with the OBX?

[pimp my yaris]

Looks intresting. Curious to see how it works out. My turbo has a .48ar turbine housing and will only maintain boost to 12 psi. It is great to 200hp. More then that needs a bigger housing with more flow and more lag.

[cali yaris]

I'm running my GT28 with .64 up to 25 psi.

[Golddeenoh]

if the gt25 are really good for response then wouldn't twin turbo kiting with a pair of those still have good response or would the split from the air flow of only 2 cylinders take away from that good response time?

[cali yaris]

^ don't know anyone who has twin turboe'd this motor. Seems kind of small to be a good match.

[Bluevitz-rs]

I think if you were to twin turbo, you'd need to use smaller turbos. You'd only have half the exhaust gasses to operate the turbo with so a smaller turbines would be needed to maintain the response.
