Hello hybrid guys - new to the forum, just finished my LS1 / wrangler project, went for a drive last night and the jeep is an animal! It looks like there are some really interesting projects going on around here, I am looking forward to reading about them and seeing them completed. Hopefully I can be of some help if anyone has any questions.

Sounds fun, got any pictures or videos? I've thought about a 5.3L Wrangle project for it would be cheaper to get the 5.3L. Guess I should get my swap project done first though!

Anxiously awaiting pics AND VIDEOS for wednesday...

Really really really try to get some decent videos. If it really looks as nasty as I think it will be...it might just push me over the edge to get my Jeep project swap going....

did you use the help of Novak Adapt? i have a 97 wrangler as well, but with 205,000 miles (yeah thats not a typo...) i think average for 97 wranglers is little under 100k eek

Ive seen 4.0s go for over 300k without much of an issue I love those motors. Im rolling up on 200,000 in my 94 XJ. And I beat on it regular...But I keep the maintenance up on it as well. I used to like them more than LS1s....but Ive been turned since doing the swap in my TA. Those 4.0s, if you take care of them, will run forever. They are a great motor.

Novak seems to have some good products, and they are an excellent source of info too, I went with Advance Adapters as I have had great luck with them in the past. I had no problems with my old I-6, they are great motors, and will last forever. I had a big cam in mine with some mild head work and it made good power with a header on it - but the desire to be different and for more power took over.

ummmm mine has the 2.5
lol
thats why i wanted to swap in a 4.8

ls1jeeptj

Well in that case you need to get your project started asap!

i want it to be a father son project but my dad doesnt want to go trhough all the chrylser to gm stuff even though it really isnt that bad and he thinks a v8 wrangler is too much power

im working on a Lsx to S10 at the moment so ill see down the line.

found a local 1947 CJ2-a for 800$ and he wouldnt budge on that either! im bummed from it.

bet if he gets to drive the s10 when finished he would want a v8 in the jeep

I also have a cj3a flatfender with a 4.3L FI vortech in it - it's a great motor for that little jeep, if your father doesn't want to go V8 I would suggest considering something along those lines! Good luck!

I'm almost done with my LS1 into a TJ project. I have a few questions for you. What did you do for gauges? What did you do for your fuel pump?

Those are really the last two things I have left to figure out.

If you went with aftermarket gauges, can you send me a picture or two?

I think it's good to post this stuff, but you can also email me at mnevitt@offroadtoystore.com

Thanks,

Mike

Mike - I rewired my chassis during this project, so I went with Autometer gauges I installed inside my factory gauge cluster. I gutted the cluster, used some abs plastic, and made a new cluster that fits behind the factory clear plastic cover. Most people don't rewire the whole chasisis however, if you still have your factory ecu, you can just leave it in the jeep, and run the jeep senders in the LS1, and use the factory cluster and the ecu will still think the stock motor is in it and the gauges will function fine. I ditched my stock gas tank and went with a fuel cell behind the seat for ground clearance reasons, and am running a Mallory Comp pump with an Aeromotive regulator up under the hood. If you have any other questions, feel free to post or you can e-mail me @ dennywal@aol.com.

Thanks for the reply.

The only issue I've had with the factory cluster is that the computer doesn't see the engine running, so it won't output a tach signal. I don't know how to get that to work. Maybe you can enlighten me. I"d love to get the factory cluster to work. The factory jeep cluster works on a a "bus" system, so you can't just interface with the cluster directly. The only possible way I could see this working is if I could somehow trick the computer into seeing that the engine is running. I guess that would take some fancy wiring from the LS1. Even then, it would be getting 8 pulses per rev, so the cpu would think it was going faster then it is.

I saw that you put in a fuel cell. I'm using the factory tank. I figured that I really have two options...

1.) I put an aftermarket pump into the factory intake system.. .I've tried to do this, but it's a tight fit, and I don't know if the intake system will work right on an incline.

2.) I use an aftermarket pump after the factory pump with a small resevoir in between. This sounds like the best system for me because it would use the stock intake system and should work pretty well at angled situations.

Anyway... thanks for your help. You jeep looks great
