Ls1 Single turbo TJ

speeddemon651 · 07-01-2009, 12:04 PM

Figured I post my build tread for my Single turbo LS1 build in my TJ

Currently I'm building a 1997 Jeep wrangler with a Ls1/4l60e out of a 98 Camaro. I have plenty of room for a single turbo setup in front of the engine and for a front mount intercooler in front of the new aluminum radiator in the grill. I also can mount the turbo high or low with a good amount of room in the engine bay. I'm going to try to post pics of how much space I have.

Previously I had a fresh Ford 302 c6 tranny and ford transfer case and It sucked, Constantly had to screw with the 4 barrel and never quite got all the ponies out of it that i wanted running a carb. Jeep came from PA. and had heavy heavy heavy salt rust so I decided to pull the body off, sand blast and paint the frame and treat any rust I found while doing the engine swap to a LS1.

So far just to do the Engine sway I have had to change the fuel pump to a Walbro 255, "stock Psi was internally regulated @ 49 psi", All new engine mounts,Daystar 1" body lift, take the tail shaft off the 4l60e and change the output shaft to a short 4x4 one. New exhaust, Radiator, Fuel lines, Fuel regulator, tubing for a intake and Air filter, Adapt the LS wiring harness to the stock Jeep one, new radiator hoses, replaced all brake line with stainless ones.

Also to mention, I re-undercoated the entire underside of the body, cut the radiator shell for my ebay front mount, Core size is 23 x 12 x 3.

cold water + hot turbo = many tiny expensive pieces.

Also I stripped the gas tank top and made a aluminum plate to mount my new -8 feed and -6 return lines.

Turbo's come on countless trucks, cars, boats, planes, tractors and just about anything, I'm not really sure what you mean about cold water + hot turbo = many tiny expensive pieces. You don't know much about turbo's do you ?

I think he was saying if you get your turbo really hot and dunk it in a big water hole it could spell disaster. I'm all for overpowered rigs though.

Carry on!

Good luck.

Make sure you put a heavy duty cooler for that transmission though. The two week points on an LS1 Camaro were the 10 bolt rear and the 4l60E. Head over to www.ls1tech.com they have a hybrid vehicle section that may have some good info for you.

Good luck!

Looks like your going a pretty good job !! What size turbo are you using ? I'd recommend something smaller like a T60 and shoot for powerband over peek numbers.

You should have done the mustang EFI on your 302, but the LS1 really is a whole different animal.

Good luck with the build and keep us updated.

ALso.... What axles you using ? I asked how long a D35 would last with a LQ4 ( 6.0L LSx motor ) and most of the responses were " how long is your driveway ?".

Ebay intercoolers ftw! I had one on my wrx.

speeddemon651 · 07-01-2009, 01:41 PM

working on the turbo manifold and cross over tube right now, and it doesn't really work that way, but what ever. Even if it did, I'm mounting the turbo up top. Going with a Turbonetics Tc78, a 60 series housing with a 78 wheel. Looking to make this thing scream

Hey man, where are you in MD? I'd love to take a ride in that thing when it's all done and lend a hand if I can! Sounds like your experience is way above mine, LOL ... that's how people learn I suppose.

La plata, pretty far south

Cool project! One thing, if you're putting all this work into it, change the tanks on that intercooler. They are of a terrible design that lends themselves to short circuiting which great decreases the efficiency of the intercooler.

^What he said. Or if you have the money, sell the 4L60E and get a 4L80E.

Do you seriously have an airplane next to your Jeep? I will also be going the turbo route but I'm saving for AEM's stand alone computer to run the set up. What are you thinking of using? I'd be glad to drive down and give you a hand sometime when you start fabbing things up.

I just went through my current 4l60e and installed all new clutches, and added a corvette servo, so it should be good for awhile. As for cooling it, my radiator has a large built in transmission cooler designed for this ls conversion from Advanced adapters.
