cooperma Posted February 5, 2014 Share Posted February 5, 2014 Just joined the board, I have a 71 240 that is about 40 hours from fully rebuilt from ground up. Well, I got a wild hair and now I want to LS1/2 it. I have a few questions to start: Who has a 71 and used the LS1 and 700r4 tranny or what auto tranny did you use?. How did it fit, what did you have to do to make it fit? Also, what are you all doing for gas tanks. Who has used a fuel cell, what manufactuer and size, and what did you have to do to make it fit (Cutting and cage to sit in) Thanks in advance! BTW, here are a few pics of the Z as it sits, Mark Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted February 5, 2014 Share Posted February 5, 2014 (edited) Mark, you would do better to start this thread again in the Gen III V8 forum when looking for advice/suggestions. Not many people cruise the Member Projects forum-it is more of a blog forum than a "Hey, I need help!" forum. Be thick skinned when folks scold you as if you haven't made any effort to look for solutions yourself. When you need something, try using the google search, then follow any sites that google suggests that seem to come from this hybridz.org site. The google search function is sometimes as good (or better) than the search function in the upper right corner of this site. Having met you last night, I know you are straight up guy and that you aren't just whistling dixie. From the looks of your car above, I expect your swap to be show quality. Hopefully you can figure out how the PM (private message) function works. When you do, send a message to ZFan1, EasTnZ, and m1noel. ZFan1 has an LS-style auto trans (4L80E) in a first-series 240z. EasTnZ just did a truck motor swap, so you can learn from him the secrets of front accessory interchangeability, and m1noel has a yellow 280z that is super clean and show quality like I think you will like. If you need inspiration, look at anything by Sunny Z, or CobraMatt, or MiKelly, sq_creations, 280zcar, Phantom, rags, (I'm sure I'm missing a bunch of folks). To review last night's conversation: Try to get a full "pullout" that includes engine and transmission with computor, and wiring harness. Try to get the dude to include the shifter handle, radiator fans, fuel tank and fuel pump, and (if drive by wire) the gas pedal. Easiest swap is with a 1998-2002 "F-body" Camaro, Firebird, or TransAm. That is the powertrain that the JCI mount kit was designed around. But it has been 12 years since those car were produced, so low-mileage pullouts are scarce. Most powerful stock engine is the LS3, but we are talking $10k for a pullout, and the T6060 manual tranny has a goofy driveshaft and a weird remote shifter. Next most powerful stock engine is the LS2 from a 2006 Pontiac GTO. You are looking at $6500 for a T56 manual trans combo pullout with low mileage, but only about $5500 for an auto trans combo pullout. I haven't seen anyone do this, but see what you think about using the GTO fuel tank and in-tank fuel pump. You can save about $1500 by going high mileage, but why do that? If going from an LS2, you will need an F-body alternator and rear alternator bracket and an F-body or Corvette oilpan, windage tray and oil pick-up. That's about it for now. Oh, by the way, your doors and hood are missing. Your car is amazing. Keith Edited February 5, 2014 by RebekahsZ Quote Link to comment Share on other sites More sharing options...
