I'm sure this has been discussed before but I was wondering what are the limits of the internals on a stock 2v? Could I safely be at 450-500 rwhp?

 

negative. 450 rwhp is the claimed breaking point for our motors. some have run that much power, but it would be on borrowed time. i would be hard pressed to go over 430 rwhp on stock internals.

500 rwhp, good luck getting it past the dyno.

 

keep it around 400RWHP. as stated, 450 is the breaking point. there's still no guarentee even with 400 though

 

Hell, you're engine can blow at stock power. There's never a guarantee, but 400ish is the common point where people either stop modding or get forged bottom end if they want more power.

 

450 is pushing it..500 and blown motor in a week lol

 

There are Sooo many variables that come into play. Any tiny problems within the engine before modifiying it will be intensified x 92255215215 once you strap that turbo or supercharger on. If you were planning on getting near the 400 mark you should first get forged internals, better to be safe than sorry. Of course the grand-am :clears throat: .... ummm ....GTO will respond waaay better to mods, they're ugly but fast as hell.

 

This is what I expected of them. thanks.

 

max400rwhp, and start saving for a new longblock, its just matter of time

 

there are plenty of people i knowrunning around with between 400 and 420rwhp on stock bottom end 2v's for a couple years and no problems...............anyone notice how the number keeps getting lower? Everyone used to say keep it under 450rwhp to be safe, now people are saying get forged internals at 400 rwhp[8D]

 

matter of fact, a guy i know is pushing 511rwhp on his '04 GT with a 2.1 KB with stock bottom end, and it hasnt blown up in the 6 months hes been using it........its all in the tune i guess
