Bdflies Posted September 11, 2020 Share Posted September 11, 2020 Please forgive me if this dog's been beaten. I have a couple of 240Z's and I’m considering an LS swap into one. I'm leaning toward an automatic tranny. Does this combo require extensive tunnel mods? If there’s a thread, point me please! Thanks! Quote Link to comment Share on other sites More sharing options...
zboi Posted September 12, 2020 Share Posted September 12, 2020 A 4l60e barely fits, mostly due to the pan width at the bottom. Any reason that you want those extra two gears and extra weight? Quote Link to comment Share on other sites More sharing options...
Bdflies Posted September 19, 2020 Author Share Posted September 19, 2020 I’ve come to understand that a big difficulty involves exhaust routing. The tranny might fit, but ya gotta fit the pipes too... I’m tackling body work now and will be replacing floor pans soon, so now would be the time to enlarge the tunnel. Just not sure I want to impose on my space to accommodate pipes. Decisions, huh? Why the 6L80? Really just spit-balling the idea. More gears = closer ratios. I’m in the research and ask questions phase. I have an L28/5spd that I can put in it. I figured to go through the L28, with a performance cam and install 3 Webers or an ITB injection system. Giving that some thought, it seems that one might swap an LS (and corresponding tranny) for similar money. I like the fab work and the technical challenges. Just developing a plan!

zboi Posted September 25, 2020 Share Posted September 25, 2020 You would be better off going for the 8l90e if that is your goal, they are similar size. I wouldn't waste money hopping up the l28, it will net you far less $/hp than an ls. Quote Link to comment Share on other sites More sharing options...
