LS Swap Syclone Single Turbo Build

Hello,

I have been on the forum for a long time and have owned a fairly stock sy for a while. I have been fairly involved in the LS scene for a long time, and was presented with an opportunity to purchase a syclone with an ls swap this summer. Its a 47k mile body, but the work done was pretty bad. I was planning on doing a single turbo setup when I purchased it, but didn't realize just how bad the origional conversion was done so it will take more work than previously expected. Plans are for a 4L80E (being built now), iron LS motor (370-402 cubes), and a single 94 mm GT5594 turbo from Forced Inductions.

I have started fabbing stainless headers for the first time from sch10 stainless weld els. I have completed the drivers side and working on the pass side currently. I started with a Miller Econotig and picked up a Dynasty 200dx (world of difference, fyi). I am fortunate to have friends who have given me advice along the way, and figured that since I have searched the net before looking for advice on projects, it's not a bad idea to share what I have learned so far. I own a couple LS based cars, and this project isn't on a "rush" status, so I will update when I can regarding new progress on the build.

To start, here is my drivers side header not quite 100% finished but I will grab pics next time I am in the shop of the finished product:

Sounds like a fun project. Post up some pictures of the trucks..... also the 2005 TT vette with 1000hp??

Was it a good basic swap? motor mounts, oil pan, 4l80e, 32 spline input for trans case?

Re: LS Swap Syclone Single Turbo Build

The only real good points about the swap are the turbotime oil pan and I can use all the ls brackets that were on the engine for the accessories. The truck had no A/C and won't for this build either as a 94mm deal is just huge and getting everything to fit is a hassle in itself. Possibly tackle a/c later on..

It had a stock reman syclone trans in it.

I would think a 4L80 would be ok.

Edit - the 4L80E I am doing is being upgraded with parts from Jakes Performance including trans brake by a friend.

I've been thinking about doing this in a couple of years. I'd like to see what all is involved first. :)

Very cool! I am just about to start the same thing! Been thinking about it since I bought the ty a few years ago since I've had several Silverado's in the past and currently and after breaking my crankshaft I am gonna finally do the ls swap! Keep us posted! Would love to see what all you've done to the engine mounts, and firewall issues, ect? Good luck with the build!

Re: LS Swap Syclone Single Turbo Build

No issues with firewall. However, the turbo isn't a small one so it is very close to pass headlight and I have yet to determine what I will do for a inner fenderwell if I even have one. I purchased engine mounts from RPM and for mock up so far so good. I did purchase a crossmember for a 4L80E trans from them that is going to require modification although I need to point out that this is in no means their fault as the tolerences in these trucks plus the differences in swaps make it difficult to make a "universal" crossmember.

I am keeping it AWD and hope that the TC will live through the abuse but no idea how much it can take.

I am by no means a welder by trade but have friends that have given advice and I have spent a decent amount of time practicing. Here is my merge to the turbo:

The vette is a pretty boring deal on the outside. I don't have many pics but just picture a silver C6 Z06 with black wheels (it's a standard C6 with Z06 wide body and powdercoated black Z06 rims).

Re: LS Swap Syclone Single Turbo Build

I have more pics, but frame has been painted. Purchased sportmachines front A Arms and coil over. Hope to have cab on by this weekend. Used POR 15 after stripping the frame from surface rust and such. I am fortunate to have a great painter and friends to help on this stuff. Once it is donw, it will be back at my shop so I can finish the tubo hotside and start on an intercooler. Going to run air to air with methanol injection.
