Hey, I just found a Stock G4cs in the JunkYard out of a 92 Expo.

I took the engine out and inspected.

The Block looks OK, no damage from out side, ether internals, When I removed the oil pan, there were no debris, the oil looks kind of sparkling things in it, (metal shavings), But nothing crazy, the debris where to hard to see in the oil, It was only visible when the sun shines the oil.

The Head gasket was missing a peace between the cylinders, Here you can see how it was.

I open the front cover and the balance shaft belt was broken, It didn't damaged the Timing belt, so there were no bend valves at all.
The pic will tell better.

This is going into my Daily Drive, so no high boosting, Road racing, track or anything like that.

My plan is, to hot tank the block, hone it, resurface, polish the crack and replace ring and bearings (Stock), I was planing on using the stock internals, which I read a thread were it was making around 300hp on Stock G4cs.

My budget is very, very, very tight, But for a daily drive, with an Evo 3 Turbo and maybe a T3 Turbonetic, I don't think I should go with aftermarket pistons.

However, I am worried about the piston shape (Top), I don't know if they might hit the valves.

I am using a Sonata 2.0 Head though.

Any advice on my build, and about the Pistons hitting the valves.

Thanks in advance.

You cant use those pistons, compression will be way to high, you need to buy some aftermarket pistons.
