Drove a Turbo Yaris

[PETERPOOP]

thanks. i haven't seen these yet. could the torque be increased with a proper dyno tune? I mean, obviously all numbers will probably increase, but is the gap between HP and TQ usually similar to what is shown there on turbo applications?

Absolutely I could increase both HP & TQ by fine tunning it with the AEM FIC. But honestly I want to stay in the 150-155HP range. I feel that is the safest range of power for the stock pistons & rods. That not to say that I couldnt make more HP just for a race or something.

I think the GT28 on a stock motor is not the appropriate turbo. It would be doggish at 6 psi. The GT25 worked great on my stock motor, it's nimble, spools fast and delivers the power range intended for the kit we're working on.

My intention is to have Carlos build a 2nd kit that I can use for a test car. With two test cars, I think we'll have solid and reliable data. We'll also all have proof (which some people will want to see) that Carlos delivers quality, on time. I believe in him, but it's faith til a kit shows up in a box, if you know what I mean. NO disrespect intended, just to be clear!

+1 on the gt28, a gt25 would be the best choice w/o a built motor and even then it can still destroy our motor at mid to high psi.

FYI & I wont claim to have always known this but a there is very little difference in between the GT2554R & a GT2854R. They are both exactly the same size physically. The only difference in the between the 2 is the size of the turbine wheel. The GT2554R is 53mm & the GT2854R is 53.8mm.

so why go gt28 over the gt25?

[cdydjded]

I think there is a little confusion here, I never said we were going to use a GT28, I said a T28. The difference between the two is that the T28 in not ball bearing as opposed to the GT28 which is. Also the GT28 is made by Garrett & the T28 is not.

thanks for clarifying that, I think I created the confusion.

As for gt25 vs gt28, there sure is a difference in spooling up.

This is getting exciting.

Let's just hope this won't be you.

Mmmm ... turbo. Sorry I got nothin'.

Personally cdydjded, I think the industrial look is great. That kit looks like it seriously gonna whoop some ass. It would have all kinds of people asking questions when U pop the hood. Being a mechanic for about 12 years, functional is always better at the stop light then pretty. Its better to spank their ass and then ask how much they spent on their chrome later!
What did U use to street tune? Is a wide band A/F ratio sensor and guage all that is needed. Or what other equipment is needed if any?

Thx for the compliments. I used the good old fashion butt dyno first to tune the AEM FIC. Eventually Ill throw is back on the dyno. Im also installing a AEM wide band soon so Ill use that in conjuction with the butt dyno...

Wait, so you tuned it by feel without knowing what AFR you are? Or did you have it on the dyno, or atleast have a handheld wideband and stuck a tailpipe sniffer in the back? Please tell me you did.

What would also be cool i think that Garm or someone mentioned in a previous thread is a downpipe with multiple bungs and one is sealed off until later use, I do not know if your kit has this already.

And whoever was arguing about the GT25 vs. GT28, joey is right, the ones that he listed are almost identical turbos with the same fingerprint maps if you look at them. There is a slight difference, yes, but nothing extremely significant. Something more substantial would be a GT2860R + or something. larger

FIC can be tuned with a laptop. My car has the EMS, but same idea. We street tuned also before going to the dyno for tweaking.

[cali yaris]

which 28 is the disco potato?

I wouldn't mind driving or just taking a ride in your turbo yaris.....Simply cause it might sway me from getting something else.
