Thread: SR20VE build with 16VE pistons

Creo que se te fue la mano en el porteo...pero bueno...suerte con el proyecto.

In regards of the SR16 Pistons this is a dead horse we have repeated this a few times.

there is NO need to notch the regular SR16 pistons with N1 CAMS. we have proven that over and over...with plenty of cars running here like that AND WITH 91 OCTANE. with some timing reduction.

gracias

Actually I also think porting was a bit too aggressive too but this is how it came when I bought it, what could be the possible negative effects of this?

On the SR16 pistons/ n1 cams combo, you mean there is no need to shave the pistons head? because right now I have the distributor almost at minimum so it doesn't detonate, specially in the 3500-4500 range at WOT.

Thanks for the clarification and advice, much appreciated!

What are you using to control the ECU? You don't need to be playing with the distributor. Just set it at base timing and tune it on the ECU.

And yes No need to shave the valve relieves or piston dome on the N1 cams with 16v pistons.

I just got a reprogrammed ECU with a base tune, but seems that timing is to aggressive for my build, so John from nismotronic is sending me some new chips to lower it and do a better fit for my build.

What's your thought on my porting?

Well best thing is to get it tuned live on a dyno but since sometimes its not an option best thing is that. Get a lower timing map. And about the porting who knows. Never seen such big intake ports. Test them out no other option.

You should not have any issues. We have had plenty of these builds years ago. My most recent was a 20VE bottom with SR16 pistons. Only thing we modified was for the oil squirters. We ran N1 cams as well as Kelford's. We were spinning these motors to 9-9500.

Mine went strong for a long time before I pulled it for my 2.3. It's still alive in another car.

Tuning is key.
