final installation of nology hotwires - Toyota Yaris Forums

on their scion xb zpi actually upped the boost to 12 psi and had about 230 to the wheels but with slicks, the snapped the axles. They said the engine held fine, now for how long is another story. I am shooting for a decent amount higher then 220 to the wheels. but yea a stock bore with beefier components would definately allow for 220 to the wheels. just be careful with our tiny axles. and taking metal away isnt too bad if like i am doing you sleeve it. it allows for a bigger bore, i'm hoping to be able to get a couple mm over bore, maybe have a 1.6 liter engine haha.

nice to know that zpi got those numbers. and if you are gonna sleeve the block then you should be more than ok to bore it. i just wanna keep the stock sleeves and replace the rods/pistons, headgasket and head bolts.

i'm not sure if i wanna do anything with the head, if any i'll just replace the valvetrain with stock size/angle units and go from there. i don't like messing with the original equipment. i just like to make it stronger.

good luck!

alright guys just to clear it up, I regapped my spark plugs down to .035 instead of the stock .044 as I was advised to do by nology and now... no more misfires at high rpms. Just to clear that up, I was pretty sure that was the problem.
