Guest Anonymous Posted December 12, 2001 Share Posted December 12, 2001 Hello fellas, I'm would like to know what is involved in doing a turbo into a 72 240. I think from what I've read the engine is basically just a drop in so I think I could manage that. Some said I can't use my gas tank, why not with a bigger fuel pump? The wiring for the turbo, how hard is it? Do I just get the ecu and put it somewhere in the car or do I need to have a electrical degree? Also, the guages, do they all work and connect the same? Just trying to decide between V8, turbo L6, or stock L24. If anyone is near me that has done this and don't mind showing me their ride and some tips I would appreciate your help. Thanks, Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted December 12, 2001 Share Posted December 12, 2001 why not turbo a tune port 350 and put that in insted of a L6 the cost would be about the same but the power would be awsome This is an experiment, sorry if it goofs up.

scottyMIz Posted December 13, 2001 Share Posted December 13, 2001 Do the turbo swap, i will tell you it's the best thing i have done to my z so far.It's still good on gas as long as you keep your foot out of it.Not all the time unlike me I have a turbo in my 76 and it was easy i did it in a weekend.The gauges hook right up i have all of them working but i put in an aftermarket boost gauge.If you take apart the donor car and trace all the wiring there is only about three or four wires that need to be hooked up.All i did was trace them and label them and it worked out great.The ecu fit right in the kick panel where the old ecu was but them you don't have a efi car so you might have to find a place or maybe get a cover from a fi car and use it to cover yours on the kick panel.Just take the fuel pump out of the donor car and it will work great.They are super cheap to mod i only spent about 600 bucks to get it into the 12's in the quarter.Could have neeb a little more or less on the price but it was cheap in my book.The motor just dropped right in no mount mods and i had an auto trans on the donor car and just put on my trans and flywheel.Just make sure the motor runs before you pull it.It will be easier to fix the engine in the donor car than in yours.Cuz you don't know if you did something wrong or not on the install if you don't know how it runs.Hope this helps we need more turbo guys on here the V8 guys are starting to take over Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted December 13, 2001 Share Posted December 13, 2001 The reason you can't use your 240 tank is there is no return line or baffling in the tank. The FI pressure regulator requires a fuel return to properly regulate fuel pressure. The 240 tank can be modified, but I've heard folks have problems with fuel starvation on acceleration or corners because there is no baffling in the tank. I believe a '75 Z tank will bolt in - just get one of those, a turbo pump and the fuel lines, then you'll be set. Quote Link to comment Share on other sites More sharing options...

BLKMGK Posted December 14, 2001 Share Posted December 14, 2001 No way, the price difference would be substantial. ZXT motors are usually sold pretty cheap judging fromth eprices that have been posted here in the past. Do a ZXT if that's what turns your crank. A turbo V8 would certainly be faster but not what I'd call very cost effective I want one though (lol). Quote Link to comment Share on other sites More sharing options...

Guest Anonymous Posted December 31, 2001 Share Posted December 31, 2001 I noticed you guys were discussing l28et buildups, I just wanted to mention that I started mine I've been taking apart the bottom end, prepping some stuff and saving for getting machine work. Anyway, this may interest you guys. The motor had about 60k from the zxt, then the fellow I bought it from ran the stock turbo a little higher with an hks intercooler, he put about 5k on a trip down to cali from canada and back. He said he had a problem with it running rich, which I could tell... black combustion chamber. Thank god rich.. and not lean. I'd rather have black chambers than detonated pistons I haven't checked out rods, crank, bearings.. I'll put new rings, o ring the block, get a 3< valve job, hot tank everything, get all of the lower end balanced... deburr and paint everything. I might go with a ceramic coating on the pistons and some others, depends on what kinda prices I can get. I have chosen to go with sds 6f.. the coil packs.. 3 bar MAP sensor, knock, fast idle.. some others, which means I have to upgrade fuel pump and injectors. I'm looking into getting some decently priced svo's or murker's, any high flow injectors I can get cheaper than 300 for six. I know that the stock ones will probably not take me to 300 hp even running full duty. As for the intercooler and turbo, I'll be looking for an npr, or spearco, any high efficiency fm i/c. I'll stick with the stock turbo until I can afford to pay a good grand on a ball bearing t3/t4 that can give me the power I need. Greddy BOV, and "A" evc, turbo timer.. some other small stuff. Anyway, this will probably run into the 4-5k mark just into the motor and turbo. Yikes! That's pretty comparable to the 2k I originally planned on doing a stock turbo setup with a slightly increased boost setup if you guys have any ideas or advice for me, I'm all eyes -mak Quote Link to comment Share on other sites More sharing options...
Evan Purple240zt Posted January 1, 2002 Share Posted January 1, 2002 It was stated before that the 240 fuel tank did not have a return line. That is incorrect. It has a return line. I would not try to run that much fuel through those dinky lines though. I used the factory fuel supply line to return and ran half inch aluminum line to the tank for the feed. The stock tank wont flow enough fuel for a turbo setup. The inlet/outlet is too small. You will need a tank out of a 280 w/fullsize spare tire. Scottymiz, im a turbo guy too I have NOT had time to finish tuning my motor. Spring will come soon enough though. Evan Quote Link to comment Share on other sites More sharing options...
