ya right.... we havent even made it to 800hp yet!

The Nice thing will be to simply swap engines and ECMs and not have to do any mods down the road.

just cause it hasnt been posted on the net doesnt mean it hasnt happened

ya right.... we havent even made it to 800hp yet!

but yet a few years ago a 5.3 with twins on it did make over 800 rwhp

They're little turbos though. at about 15 psi i might make 700ish. At which point the factory head bolt will probably stretch and the heads will take off like rockets. And i'm not really looking to lift heads. I figure low boost and high compression will give me great fuel mileage and plenty of power for a turbocharged engine. If it works out, I'll build a second kit to match and somebody else with a rear fuel cell can switch over to this system fairly easily.

The oiling system is one element that will take some work. I don't want to put 30k on a kit only to have an electric oil pump malfunction and burn up both turbochargers. But then again, i don't like the idea of mixing the turbo-oil with engine-oil. So i may look into a separate oil system that can be driven by the engine. I'll have to be able to regulate the pressure, and it will need a big oil cooler as well as a good filter system. So maybe a single stage belt driven pump for a dry sump system will be the way to go.

Moroso PN 226000. External Wet sump oil pump with accessory drive kit. I'll probably have to build my own pulley for the ls engine accessories, but I think this well be the solution. I would dearly like to find a cheaper alternative though.

Anybody need an auxiliary oil pump for say, a turbocharger or something? I got to work on a prototype today and got something that will definitely feed a turbocharger. and it installs with hardly any mods. Just plumbing.

Let's see some pics then.

I'm pretty sure Mitch was north of 25 before he took out a head gasket, with stock parts. ARP head bolts are around $110. Just a thought.

Old power steering pump FTW. I think a regulator downstream from a power steering pump with at least one oil cooler and filter will make a good oil system.
If i can find a pump with the shaft extending out of the back of it, I could attach another pump to the back of it so they would run on a common shaft.
