is a 75 shot safe on a b16 with stock internals.

 

I wouldn't do it, but it's your motor & $$.

 

what about a built gsr bottom with ctr pistons,etc. and fully done si head, it's built all motor, 75 should be no problem for this motor right.

 

depends on a lot of things like compression, fuel, piston rings...

I'm not a fan of nitrous unless it's used as a final upgrade to an already monster setup made to handle the stress that nitrous has on a motor.

CTR pistons are still OEM... and higher compression. If you want to run nitrous 'safely', get aftermarket pistons/rings made for nitrous, imo.

 

I've never really trusted nitrous systems on cars, especially stock motors.
The gain is just not worth the risk, in my opinion.

 

I couldn't agree more...

 

Compression and Leakdown test will tell you what condition your internals are in. You can make a judgement call after that.

 

As long as the user has common sense then nitrous is not an issue. i dont understand where everyone gets these bad ideas about nitrous.

It is by far the best bang for your $ that you can get.

 

I'm not arguing that at all, I'm just saying I don't trust it in my motor.

Maybe after getting some parts replaced, but it is not worth the wear you cause on the motor.
