pistons and rods
so im wanting to up my power and from what ive been reading the rods are the weakest link on the g.... so would just lc pistons and rods be good for 600whp? i have a 60-1 turbo and only going to about 500rwhp but just want to find a little more about these engines and such... also what about the bc stroker? better for n/a or the same as boosted?
oh and if i do pistons rods and a cam what could i raise my redline to?
thanks guys

I would suggest setting a goal. Ex 500 hp and what will it take to get me there. Talk to the people who are going to be building your car and ask them what they would suggest using, then ask others.
If you are going for 500hp you do not need a stroker kit. It can be gone with pump gas, rods and pistons, and other supporting mods. How many lbs is going to be determined by the turbo output and tune.

Cosworth internals all the way! and If you are trying to make over 600, darton sleeving would be the way to go as well. I have been told by a few really great engine builders that stroking a motor and big boost does not go together. If you want to make more power, up your cfm. Thats just my 2 cents

im only going to be making around 550whp for now so im keeping the stock sleeves and doing pistons and rods... the block thats in the car now is going to be pulled and fully built after i get the new one in but its going to take me about a year to build it as i have other **** to take care and cant drop every penny into and plus i want to take my time and do everything right...

I have read this in a couple of places, no first hand knowlege mind you, for high HP VQ motors (600+), the weak point is where the cylinder meets the head. During high rpm, the cylinder itself will start a harmonic vibration that will eat up the head gaskets.
Note there is no support between the cylinders and the main block at the head/cylinder interface
If you want a high HP motor, you must support the cylinders through the water jacket to the main block. As I'm sure you know, proper fasteners and tqk specs will stop part of that.
This one is properly sleeved and supported.

yea this semi build will only see around 550whp so i think ill be good but like i said with the bigger build i wanna take my time and do everything right so it will take me a while to have it done which is ok since im in no rush
are those aebs sleeves in the second pic?
and its called wet sleeving when it in contact with the coolant with the holes in them.
