Jeep Driver Posted March 19, 2020 Share Posted March 19, 2020 I want to see a couple of success stories. Daily drivers, no tuning problems, no overheating, everything fits under hood. I've not seen a success story, not one. Link to comment Share on other sites More sharing options...

Sent from my SM-G973U using Tapatalk The turbo manifold is under $400 from boostwerks, turbo itself is cheap (that version has an internal wastegate that personally I wouldn’t run). Your basically paying almost a grand for a downpipe (which is how much his down pipe is on eBay). My exhaust wouldn’t even be compatible since I use a TJ downpipe that wraps around the front of the oil pan. Link to comment Share on other sites More sharing options...

Daily drivers, no tuning problems, no overheating, everything fits under hood. I've not seen a success story, not one. Are you specifically referring to Comanches and the 2.5? Renix? What's your metric? There are a lot of JTEC and NGC success stories. My TJ is a daily driver, 5.13s, 37s, 6 speed. As I said before, not a huge fan of the Split Second but it operates fine. I don't like that I have to tune two different computers so I'm swapping in larger injectors and a 2bar map and remapping the factory PCM, ditching the Split Second entirely. But the engine loves it, drives great, never overheats. And there are a lot of people cruising around with the Banks turbo setup, a little less homebrew. I don't see why an older 2.5 or 4.0 wouldn't be happy to be boosted, the approach will just have to be appropriate. Address fuel. Address timing. I retard 1 degree per psi and aim for a slightly too rich, and safe, afr. Link to comment Share on other sites More sharing options...
ghetdjc320 Posted March 20, 2020 Author Share Posted March 20, 2020 I agree. I don’t see any problem with boosting a 4.0 as long as you get the tuning right and I also agree that the split second is not the best way to go. Afr’s go a long way to keeping your engine temps in check as long as your cooling system is working as it should. Link to comment Share on other sites More sharing options...
