too bad you can't take full advantage of the compression with bigger cams

So any update to this? Still running? Dyno? Also I was wondering what engine managment you are using to run these. Stock, piggyback, or standalone? Where did you souce these from, new or another engine.

I'm guessing he blew up the engine. That is way too much compression to be running on pump gas and cast pistons. To run as much compression as he had you would need forged pistons and run race gas. Mother wise you would not be able to control detonation. Of course, he could prove me wrong by posting an up date, but physics predicts that he won't be doing that.

@Viperoni
I dont think its the "power" that he is referring to that will blow up the motor, but the compression itself and not using correct precautions. We will never know because OP hasnt updated

i was referring to should it function what would stress out first. valve clearance would be the first issue maybe a shim gasket to gain clearance and lower compression ratio while also adding block guards might work great.

too bad the project isn't work, i still really curious about the result if someone can swap this piston and have about 12:1 compression ratio in 1nz-fe engine. toyota 1NR-fe engine series have 11.5:1 compression ratio, so i think actually it is possible to have 12:1 too.

04-07-2013, 11:27 AM | #53 |
I think 12:1 is possible and even 12.5:1 with premium gas. the prius pistons are 13:1 so it is pushing it.
MicroImage has higher compression pistons for sale but i don't know of anyone that has done it. his 9:1 pistons are very popular in the boosted community. |

With that we'd be hangin' out in the FRS compression ratio arena.
