Hello, I have been lurking the board for a bit and have finally decided on what my plans are. Initially I wanted to go right at a 5SGTE build but later thought I should build the engine first so it can handle the boost and do it right the first time. Soo....here is what I am thinking about doing unless anyone objects or knows of something to do instead:

Buying...
Wiseco forged pistons/rods 86.5mm (.020 over) 138mm rod length 22mm pin diameter
Rod bearings
Valve seals
Lightweight flywheel
Axle Assy's
Front hub bearings

Machine shop...
Resurface head
Valve job
Bore/hone block
Port/polish head
Grind crank


I will be doing a dyno and taking lots of pictures before so I will know if this was even worth it. Would anyone suggest not boring the head and keeping the stock 86mm pistons and save the money at the machine shop?? I just don't know how much bang I can get for spending the extra bucks.

Also, buying through Wiseco, they only have a part number for a 3SGTE block but the 5SFE block is the exact same right? So the rod length should be ok? Anything else I am overlooking?

Thanks,
Don

NO. You need to do some more research. The 3S has 86mm pistons and 86mm stroke. The 5s has the same block casting but the block itself is very different.

Does anyone know where to get 5S pistons. I can't find anyone who sells forged pistons online or locally for the 5S.
