Wow, that's quite a combo! That turbo is almost bigger than you need :shock:

iv already purchased almost all the engine and fuel system parts and so far so good. Iv also dont almost all of the metal work but im a school right now so it prolly wont be done until late summer (or atleast running). please post some pictures of your setup when things start moving along. i have heard of alot of people trying this set up but havent seen one complete. i dont mean to jack you thread but here are some pictures of the progress on my z

just wondering if you got the engine in or test fitted yet. id love to see some pictures of how it fits. spring break is coming up in about 3 weeks. i hope to atleast test fit my engine.

the cam will fit, no problems. the heads fit but the intake valve (or it might be exhuast) on the ls1 head is slightly larger. the valve will likley hit the bore. if you bore out the 5.3l or if you have a 6.0 block, it will work with no problems.

 

the two engine as so similar that they even share the same rods and crankshft.

well i got the motor into the car and i started to test fit everything and would'nt you know it the main part of the turbo stuff does not fit so now i am left with either cutting the hot pipes and making them fit or selling this stuff and just making my own oh well,

Jamar, what exactly "does not fit." Most turbo installations are custom and have to be "fit" as they are installed. Give us more details and maybe someone can offer suggestions to help you. You are going to run a single turbo, which is, by definition, easier to install than a twin turbo system that both Hanns and Silicone boy are running. Details, man.

What Davy said.. Also what type of manifolds are you using? 6.0 casts or customs? i'm really interested in this because I'm looking at a Single setup on my LS1 240z. Thanks

i have a setup simular to the sts setup that is made for the camaro, in order to use the manifold i will have to cut the turbo flange off extend it about 3" and have the flange facing upwards so that the turbo sits on top and then have the downpipe run to the back and down near the fire wall which means that everything has to get ceramic coated so that the brake reservoir does not get too hot and then comes the passenger exhaust manifold which i have been researching and i think the best way to route this is down in front of the oil pan and up to the opening on the driver side exhaust manifold but i think once all that is worked out i think that the kit would be real easy to work with and i will post pics of what i am talking about later BY THE WAY I HAVE A VERY GOOD FRIEND OF MINE THAT DOES TUNING ON THE LS1 COMPUTER AND IF YOU GUYS ARE INTERESTED IN GETTING A TUNE OR GETTING STUFF DELETED FROM YOUR PCM I WILL ASK HIM IF ITS OK TO POST HIS NUMBER ON THE SITE AND AS YOU KNOW THAT THE LS1 WAS TUNED FAT FROM THE FACTORY SO THAT PEOPLE WOULD NOT BLOW THIER MOTORS

Hmmm, I'm trying to visualize what you are describing and it's not easy. If the trurbo is on the passenger side and you need more room, consider removing the battery tray/supports to gain more room. The turbo will sit on top of an inverted exhaust manifold, correct??
