Thread: SR16VE Pistons And SR16VE N1 Pistons

i wonder if anyone else is running the pistons un shaven on 93

Wish I had 93 out here I would let u know. On 91 I had to pull a lot of timing out on the bottom and top to keep it safe.

was it woeth it?

Not sure yet. I haven't mixed up some gas yet to put the timing back in. They were free so since my motor is running again I guess I could say it was worth it lol.

Its all up to you of its worth it, I kno I pulled my motor apart and put them in total gain after tuning was 5whp.. pump gas

how was the mid range and top end on the dyno sheet. before and after? i do not understand y so little power is it the ecu that hold our cars back? because we should be producing more power than honda b20vtec and lsvtec but sadly we dont

The gain from that jump in compression is about on par. The car gained pretty much everywhere, top end help pwer better. Tq increase was not significant. Again, the only idff on that test was the pistons everything else stayed the exact same. I even tried running 103ish oct and tuning but only gained like 2whp and a few ftlbs..

My pistons did have slightly deeper valve notches machined in so the cr would be about .3ish lower then std sr16 piston.

wanna ask normally as u said.. if we using sr16 n1 piston to sr20ve how much whp and torque we will gain? is it a lot on the mid until high rev? as i know if using the sr16n1 piston at sr20ve bottom the compression is aroud 12.1. but dont know how much gain we can get?
