Hey I have a b16 in my ef with 12:1 comp. pistons and I am currently building a b16 low comp bottom end. And I want to boost it with the 12:1 comp. pistons in it to see what it will put down. Let me know if anyone has done this and what will it put down. And is there anything major that could go wrong.

Here is more info on the motor

-The transmission is a JDM SiR cable trans.
-The head is put together with InlinePro dual valve springs and titanium retainers. The valves are brand new Honda OEM valves, and I just had the head resurfaced before re-installing, as well as having had all the valve seals and guides replaced with OEM Honda parts.
-The bottom end is built using CTR replica 12:1 compression high-rise pistons, with shot-peened rods, ACL race bearings, and a knife-edged and re-balanced crank.
-It currently has Buddy Club cam gears bolted on to GSR cams.

I was going to get new cams and it is tuned on chrome right now.

 

I doubt this car could be a daily driver. Make sure you bring it to a really good tuner and run it on race gas.

 

I just wanna see what max whp i can get out of it and see how long i can dd it before it blows lol then put the built low comp bottom end in. I am just seeing if anyone has done it or if it is just a waste of my time thanks for your comment

 

Its not a good idea especially if you running it on like 91octane.

 

What you said is very possible to do except the daily driver part. Unless you want to daily drive it on high octane.

A compression ratio of 12:5:1 all motor people talk about it being risky to run on pump gas. So imagine when you turbo that motor. I say go for it if this will be a track car 1/4mile; but, just not on pump

 

sell your built bottom end and buy more stuff for your build. no sense in blowing it up just for fun... unless it was a stock sohc.

 

12:1 is going to be too finicky to run in my opinion. If you are set on trying, then consider switching to E98 or some other high octane fuel.

 

yea when you hit 11:1 comp is usually when u need to uping ur gas to something other than pump gas to be reliable and hi comp turbo builds are a definately waste of time and could ruin more than just your bottom end

 

thanks for the info I put more specs on motor
