Guest BadKarmaCreepin Posted October 15, 2002 Share Posted October 15, 2002 what would be the downfall of this? and would it be cheaper and/or easier than building a seperate motor? Quote Link to comment Share on other sites More sharing options...
inZane 240 Posted October 15, 2002 Share Posted October 15, 2002 I would be afraid to push the boosted n/a engine past stock boost. View this turbo setup as only a temporary solution until you can afford a 280zxt engine. Just my opinion. Most of the time you can find L28Turbos with everything included (manifolds, turbo, injectors...everything) for the same cost of buying individual components to turbo your n/a engine. It might even be cheaper. Quote Link to comment Share on other sites More sharing options...
Lockjaw Posted October 15, 2002 Share Posted October 15, 2002 Here's my .02/ If Nissan thought that engine was good enough, they would have used it. Granted about the only thing they changed was the pistons and the oil pump, the fact remains they felt the need to do so. Also, the NA pistons have the rings on a different location. Be careful with the boost and you will likely be ok. Quote Link to comment Share on other sites More sharing options...
Guest BadKarmaCreepin Posted October 15, 2002 Share Posted October 15, 2002 ok, nevermind then, i'm just trying to get this engine done as painlessly as possible... Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted October 15, 2002 Share Posted October 15, 2002 I'm running about 13 pounds of boost on a high mileage stock L24 bottom end with a P90 head. t3/t04b turbo, medium sized front mount intercooler, 280zxt electronics, 370cc/min injectors, 2 1/2" exhaust. I'm using the turbo oil pump, oil cooler, and turbo head bolts. My compression ratio is pretty low 7.56:1 though, and that helps a lot. I've had pleanty of fun with my setup, although I do plan to go with a L28ET bottom end at some point. If you haven't turboed before using a crappy block to learn on may be a good idea. That way you learn what you should do when you go lean, or ping. The learning part is what takes life away from your bottom end. Quote Link to comment Share on other sites More sharing options...
inZane 240 Posted October 15, 2002 Share Posted October 15, 2002 Is there a write-up on integrating the 280zxt electronics into the 240z's harness? I know there have been plenty of requests, and even partial write-ups, but has someone takin the time to do a full write-up yet? Thanks guys Quote Link to comment Share on other sites More sharing options...
inZane 240 Posted October 15, 2002 Share Posted October 15, 2002 Actually I guess what I really want to ask is...Is there a full write-up on the L28T swap? I think I already know the answer though... I know it's easier compared to the SBC swap but it would be nice to have that step-by-step documentation. Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted October 16, 2002 Share Posted October 16, 2002 I'm not sure, but I think my small amount of writing is about the closest right now, I've got some pictures I've posted to others on the list. Maybe I'll put it all into one page some day, or if I go crazy, a book. http://www.zhome.com/~aktar/zcar/73/turbofi/ Let us know if you have any questions, I'd even consider helping out of the phone if you needed it.

inZane 240 Posted October 16, 2002 Share Posted October 16, 2002 GO CRAZY GO CRAZY....well just kidding. What do you think the most difficult part of the wiring was? I want to get all of the information I can before I start the swap. For simplicity's sake. Thanks Tony Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted October 16, 2002 Share Posted October 16, 2002 The most difficult is figuring out between a yellow wire that's used for temp and power to the ECU, and another yellow wire with white stripe is either A/C stuff or coil trigger wire. These wires that are in the same damn plug can confuse you if you don't keep track of things. Also there is no wire to ground the coil igniter (mounted on the coil's base), it gets ground by being screwed into the chassis, this threw me for a loop. Everything else is pretty strait forward, just plug it in the same way it was plugged into on the ZXT. I didn't use the relay that is on the passenger side, and didn't use the circuit that turns on the fuel pump, so that further simplified wiring. Just wireing the fuel pump to come on with the ignition. Quote Link to comment Share on other sites More sharing options...
inZane 240 Posted October 16, 2002 Share Posted October 16, 2002 Are you still using the original 240 fuel tank? I know you are supposed to swap it out in favor of a 75 our put in baffles, but can you get away without it for awhile? Quote Link to comment Share on other sites More sharing options...
