Lets make a Yaris Real Fast.....

[Blown_xa]

Build the motor. It's weak. I have been through 5 or 6 motors, 150whp (DD dyno uncorrected) is the limit for hard driving I know this all too well. Maybe a bit more if you just plan to drag it. I was able to pull a 14.01 in the 1/4 on a stock motor, I don't think anyone has been able to touch that yet. in a stock 1nz-fe.

Build it and turbo it. Custom manifold and large turbo maybe if you want big numbers, nothing bolt-on will put down big numbers unless you run nitrous also. The HKS and Greddy kit have tiny turbos which is alright but max out around 200whp.

If you do it, race it! Rock it! there are only a handful of big number 1nz-fe's in the US that put down crazy power, but I never see them race!! Im lonely!!!
