Turbo Questions

[Nexus1155]

Wait, i have a question Castrex since you seem to know alot. What AFR is Cali running in boost, and I have a K03, will the low end torque end up killing the rods because of the quick spool? I really want to turbo the yaris, even if i don't add a BOV or intercooler etc, like Richards kit

Well.. that is a question for Garm... nof for me! I just know that he has mentioned a couple of times that he is running lean at WOT... but then again that is at 8 psi and 180whp

And no, you won't throw a rod... a K03 will not spool any faster nor provide as much power/ torque as Garms GT25R and he has not break anything so why would you?

Then again... what I'm trying to say is that if you are not looking to go near the limits and you can be satisfied with a low boost set up... you could do it with no tunning....

4-5 psi no intercooler... or a small one

And a cheap small turbo like the K03 or even a bit larger turbo if yoou want it to spool later... perhaps a take off from a wrx...

stock injectors or some just a tad lager like the injectors from a 1zz 1.8L

Colder plugs, premium fuel...


And you should be good to go!! with maybe 125-130 whp and about a $1k
or less spent...

Oh... and in case we found an affordable way to tune fuel and timing on this car on the future... you will only need to turn the boost up!! as you ill be all set.
