Just wanted to share this: turbo 1NZFE - Toyota Yaris Forums

Found this, a turbo 1NZFE. The car is a Thai Vios, a Southeast Asia market-only car. It has basically the same internals as the old Echo. Here's an excerpt:

Quote:

Now we come to the juicy bits. The 1.5 16 valve DOHC VVT-i 1NZ-FE engine has been turbocharged with light boost pressure as the compression ratio of the engine is still quite high for a turbo-ed engine at 10.5:1. Normal for a bolt-on setup. The ECU has been upgraded to detect boost and adjust air-fuel appropriately.

This results in 143 horsepower at 6400rpm and 196Nm of torque at 4400rpm. The gearbox is a 5-speed close ratio gearbox for maximum acceleration. This takes the car from 0-100km/h in 8.1 seconds. The car does the 400meter sprint at 15.9 seconds.

I suppose if you can lower the compression to something like 9:1 you could boost it up higher and get even better performance out of it.

More here.

Υοu can have the same result with a TTE supercharger and you keep the warranty intact!

Very interesting and quite rare car, this vios turbo...

paultyler_82 · 10-12-2006, 06:50 AM

that's one of the reasons the 1NZ cant be force fed large pressures is the compression ratio...

eTiMaGo · 10-12-2006, 07:40 AM

as far as I understand shorter piston rods would reduce the compression ratio, right?

That changes the stroke and you will lose too much torque.

Better off changing the pistons to change the compression or simply rechamber the head domes.

You'll see TRD USA with a FI option within a year in the states.

yes it would, but it would have undesirable side effects, best thing would be to go with a lower compression piston... an 8.5:1 would probably be great for a FI 1NZ

I dunno... I seem to hold little faith in TRD these days, with the vehicles they've neglected, as well as their tendancy to price gouge for parts.

I'm new to the Toyota scene so my knowledge on the subject is limited, but so far I don't think they're all that bad. All of their parts so far seem to be competitively priced with other aftermarket options, however sparce they may be. I don't see Toyota neglecting the Yaris... the aftermarket demand goes up every time a male under the age of 30 buys one, and these days that line is blurring more and more. My stepdad is 38 and I just convinced him to put HID fogs on his 325xi, haha.

Case in point, look at the demographic this forum feeds off of. How much money is spent on YW.com alone in a week on the Yaris aftermarket? Better yet, ask the sponsor's wallets.

But yes, when TRD does come out with a FI kit, I agree... it is going to be one expensive box.

Katana · 10-13-2006, 06:47 AM

Well it will be expensive, but you get to keep the warranty!

Thicker head gaskets work as well, so long as you dont buy them from 'Freds Discount Gaskets'....
This doesnt usually net you too much in the CR department, only helps.
If your going to rebuild the engine look at buying a totalled xB and pull the motor.

As long as you don't overdo it on the boost, the OEM gasket should hold up fine, but if you want extra insurance I would get some better gaskets, and while you're at it, some better head bolts... I wonder if ARP makes some for the 1NZ-FE

Just to give an impression of the performance difference with a Vios Turbo...

About a week ago, my friend and I went to pick up another friend from the airport. Keep in mind none of us are lightweights, between 80 to 90kg each.

Anyway we're on the way home, my friend is driving, the other friend just shooting video of the sights, and a Vios turbo zooms past... We tried to catch up, and you can see the rest for yourself here:
