Stock engine internals 2g

[robbversion1]

About how much hp can you push a 2g stock eclipse gsx engine before the internals fail?

That depends on not only the condition of the engine but how well the engine is tuned. A few members here have exceeded 400awhp on a stock 2G 7 bolt bottom end. That seems to be very near the limit for the 7 bolt con rods. They usually start bending or just plain snap off before reaching 450awhp. Which is way more than the average member here would ever need or be able to harness on the street.

yea i'm not even sure what i would do with 450 whp on the street. Sorry for sounding like a complete noob, but what is 7 bolt? I was looking on some other forums and heard them mention a 7 bolt flywheel.

The early 1g 4g63 engines were 6 bolts. (89-92.5) The later 1g engines were 7 bolt bottom ends. (92.5-94) The 2g were all 7 bolt engines. (95-99) The 6 bolt engines were stronger from the factory.

6 bolt and 7 bolt designates the number of bolts that hold the flywheel on. As Zach stated, depending on condition, tune and overall condition of the engine it varies as to how much power you can make but you can expect a max somewhere in the 450hp range.
