How much power will the stock rods and pistons handle?

[Turbo4L]

Hey guys wanting to get some sort of idea on how hard we should push our early model 1uz motor.

We did make 363rwkw before but we would like to make 400-430.
GT8 your about the only person in Aus that would have an idea?
Also what have you done to your motor, valve springs? head studs?

Cheers

....you might want to add to that equation, how much hp can the early 1UZ engine produce "in general".
Let's assume the stock pistons & rods can handle "anything" you throw at them...then cams + intake etc. become the limiting factors.
Figures i heard/seen sofar are 540 rwhp (+/- 400 rwkw) as MAX....so if you are already making 363 rwkw, maybe you are already close to max.
Maybe gain an extra 40 rwkw ?...and reach the limits of the cams, intake, valve springs etc ????

On the other hand I hope you prove everybody wrong and make the 430 rwkw (+/- 580 rwhp) an that STOCK early 1UZ ! :You_Rock_Emoticon:
