1NZFE K1 by Carrillo Rod interest list

ok noob question. So if I'm planning on building a turbo motor all I need is bottom end parts ( crankshaft, rods, pistons, sleeves )? No head parts? And with all this upgrade parts how much boost can these parts and motor take? :)

well, essentially, if you want (a lot) more boost, you gotta eliminate the "weakest links" in your engine, in this case, the rods. It's also good to uprate the rest of the bottom end, since that's where there's the most stress from the higher compression.

You don't even really neeed to change out any bottom parts if you go for a sensible amount of boost. When we talked to the local TRD guys here, they only recommended pushing the engine to about 140hp on stock internals. But, others have been pushing the 1NZ way past that, and results may vary. I think Tamago's gone through a couple engines already with his ghetto setup

The top end is relatively strong by comparison, making modifications to the head of most engines is related mostly to airflow and timing.

How much boost you can run, in the end? well, we'll have to wait for cali yaris to tell us, and he won't be happy til he sees 300whp And, the more money you throw at a project like this, the higher the results you can see... FYI, 80's F1 cars used 1.5L turbo engines producing over 1000hp. Of course they were of a very different construction than our economy engines!

actually, no, just a transmission and set of axles :) the engine is fine! the one i broke before was stock
