Another Turbo Yaris Coming Soon!

still not sold on the idea of turbo, especially with stock internals, w8n for better internal parts to come out if not 3.5k can get me a jdm 2zz w/tranny

the internals are already out? :)

Honestly, 190HP is not a big deal for the internals on these motors. I can imagine that if you went hi-comp on the pistons you might want to look into better connecting rods, like you would with any motor, or just have the stockers balanced at least. VW's get 240+ out of a 1.8T all day long with a stock K03 turbo, chip, intake and exhaust with stock parts. Those motors are 10:1 compression as well, so it's fairly hi-comp for a turbo motor!

Beyond a good ZPI clutch and limited slip diff and bigger brakes, you're probably set. If you wanted to pump a 30psi Turbo, Nos and hi-comp pistons you might want to look for some new internals... or a different car. =)

Don't be so sure, like Doc said, these cars were built for different things. There is no need to over engineer a rod on a car that is made for gas milage. But when you have a turbo charged motor that has to see boost for the majority of driving, you'll make a little bit more beefy rod. I had a 1.8T and it made 370whp with a 50 trim t3/t4 on a bone stock motor. Also, the 1.8T is 9.5:1 on some motors and 9:1 on others.
