Stock manifolds reversed or shorty headers for turbo

[SavageZ28]

Hello I am going to begin piecing together my turbo build and I was wondering what would work best, the stock manifolds reversed or some shortie or mid lengths? Which would get me the most gains or does it not matter what type of manifolds for a turbo build? I'm planning on pushing only 5-9 psi and hoping for 500-600hp with a turbo cam. Also where can I get some forged pistons for the stock block? The only ones I can find are for a 4.030 bore. Or something simular. Any help would be appreciated.

I don't think anyone's flipped stock manifolds for clearance reasons. Shorty headers are used a lot (BBK's seem to be the most prominent) but even those aren't flipped. Only forward running headers I've seen have been either custom made or the ebay ones.

They would be like this. I just didn't know if the power gain would be more with shortie or not when it comes to turbos @Fastbird

The hotside posted was mine. Fit well, had to delete ac. I made 426/511 with just that hotside, an eBay 70, and a walbro. 7psi. I wouldn't expect crazy numbers but it was a fun street car.

LOL, I don't know why but I wsa thinking flipped upwards. I'm braindead today. The shorties would do better than the manifolds.

@ryanstout that's about all I would expect until I actually build it. So did you replace your pistons? @Fastbird don't worry man lol we all have those days

[Ryan Stout]

Nope. Stock down to the tune. No fmu or anything LOL. Just a walbro.

I'd go shorties for sure. I'm running cheapo shorties now actually.

I bought these off eBay a while back. They were $400. I probably won't ever use them. Let me know if you're interested.

@ryan_stout how long did it and up lasting? @firebird_1995 those are sick! I wish I had extra money for those. Do you remove what brand they where?
