Thanks.. Are the drive lines different between the 280zx na and turbo? I don't have the time or money to make a custom drive shaft. I thought the 280zx's had an over drive. 1:1 does sound like a final gear, but is there a higher over drive above that? I'm pretty sure the maxima has over drive. I'm looking for good highway mileage with good low gears. The gears in my old 3 speed nicely spaced, but third gear wasn't good for crusing above 65mph. I know the 5 speed would probably fix this problem, but I'm keeping cheap and don't want to buy a new clutch kit and resurface a flywheel. Also, not sure if a standard clutch would hold the power.

My orange turbo 240z broke the 3 speed auto that it had in it while driving hard. There are some metal peices in the pan, and there is a metalic rubbing sound when in gear. Just got done pulling the tranny, got dark before I could grab the converter. Anyways, earlier today went shopping for an auto tranny out of a 280ZX because I'd like to have over drive. Do the Maximas that have the L6 bolt into z cars, and use the same drive line spline setup? Any difference between the 280zx tranny and the maxima tranny? I saw a diseil maxima, any difference in that tranny? Most of the trannies in the junk yard have like 200K miles on them, should I not even consider one of them? I was thinking the maximas probably weren't driven as hard as the z's. Also, does the 280zx turbo tranny use the same type of drive line, and bolt up the same way? I thought maybe it had a larger drive line, kinda like the borg warner t5 tranny, but may be wrong. Is the turbo tranny stronger than the non? Anyone know where the are posted gear ratios on these things? Perhaps James T knows about these guys.

Need to finish my 7m-gte dealie.. Other wise I'll bring the orange car with the L24ET.. Kinda a native engine with bolt ons though, so donno if I could hang with the hybrid dudes in the car.

This might be a fun thing to read: http://www.pickuptruck.com/html/stories/sidewinder/page1.html The inline 6 would probably fit well in a z car

Yeah, I put a bycicle lock on my intercooler when I park it Hope to have an air dam soon.

I never got it right.. Man, my car is screaming for a paint job, and an intercooler alignment... I opted to weld a bead around the inlet/outlet pipes. The hose with cloth in it seems to do a lot better at not slipping, although I have this one 3-2 1/2" reducer at the throttle body that is pretty heavy duty rubber that seems to stay well with a set of T bolt clamps, and no bead. Nothing near 25psi, but it has seen 15, and the ocational - Ooops a vacuum hose must have come off 20 or so psi.. Will definately be replacing my bottom end because of those times, oh well get to go bigger this time. Lemme know if someone in my area is looking to rid of a L28 bottom end, I've got a set of turbo pistons to drop pop in. Best of luck getting things aligned better than me, give me some advice after you get it right

I bolted a t04b compressor to a stock 280zx turbo turbine housing. The 300zx housing is just the same, so no upgrade there. Donno my power output, and I'm only 2.4L's. Would be better off getting an upgrade turbine setup. Look around on ebay, I see some pretty good deals on t3/t4's sometimes..

Would be interested in more details such as condition of the hybrid setup and the a/r's, trim, and if the t3 turbine is clipped or upgraded. Water cooled? Would love to see pictures of the big one, always like to drool.

Here is one way that works as long as you have a little bit of gas in the tank: Drill and tap the drain plug for a 1/4" NPT You can drop a 75 280z tank in, or feed a small tank that won't get bubbles in it with a low presure pump, then off of that use your high presure pump to feed the engine.

After giving the advice I think I deserve a little advertisement space here. If I'm wrong to do so please flame me Here's my very nice 280zx turbo air flow meter for sale one ebay: AFM eBay link And I also have a 280zx turbo computer up for sale as well. Tested, so there is no doubts: eBay link for 280ZX Turbo ECU

A lot of these answers have been answered in previous threads, so do some searches. Although I'll try and give you some quick responses. The engine fits with no complications. A different down pipe is required to hook the exhaust up to the back of the turbo. You can bolt your manual tranny over to the engine that originally had an auto tranny, just swap the flywheel over to the engine, and bolt everything else up. Pretty easy, swapping trannies with L series engines is generally pretty easy except for a few exceptional trannies, ie the Borg Warner T5 tranny that comes in the 280zx turbo is a bit different, but still can be swapped with some work. The stock 280z clutch may not be strong enough to hold the added power for a long time, so an upgrade might be something to consider, although you could get away running the stock one for a while if it was in good condition. If you are swapping into a 280z the stock fuel pump should be able to deal with stock boost, and should have no problem dealing with up to around 9psi or so at which point you need an intercooler. If you plan on using the stock 280zxT EFI system then get as much as you can. Get the distributor, complete EFI harness, AFM, o2 sensor, head temp sensor, ECU, coil igniter (mounted on coil holder) throttle possition sensor, and optionally the idle control system components. The relays are not important to making the system work, but if you are comfortable with using relays then it might make you feel better that you have them. You do not need to have the EFI system control the fuel pump, you can wire it up to come on when the ignition is on. This will make wiring a little less complicated, and when you decide to upgrade to a different pump you will have less issues. There are many limitations that come along with the stock efi system, and if you have the money to jump into a stand alone engine management system then this will rid of a lot of head aches in the long run. A lot of us are running on the stock 280zxt EFI and can make over 250hp to the wheels with larger injectors, intercooler, larger fuel pump. When running larger injectors on the stock efi system the car will run pig rich at idle and medium load. This causes bad gas mileage, and a raw fuel smell which is no fun. If you intend to stick with the stock injectors and run 9psi or less boost then there is no reason for you to go with the stand alone engine management system. This would put you into the low 14's in the 1/4 mile.

Ack, why the supra owner bashing? I agree with the rest, the big T series are probably not the way to go with the L6. I think the weight of the supras also help keep them under a lot more load to get that air flowing for those big turbos. I don't know much about the new t3 turbine setups, but I don't think you could go wrong with a t4 P trim, low a/r and then put one of the largest compressors you can bolt on for the small shaft setup. Going to big shaft probably will only make more time to spool, and unless you get a BB setup it could be a big pain.

hope to see pics of the gasket after you pull it out.

Try that out, if it doesn't work you can rebuild it yourself with a kit. The kits are selling on ebay now for pretty cheap, like $40 or so. It doesn't take any special tools, but somtimes the bolts in the turbine housing are a little stiff.

Had a friend with a vr6 VW, not sure of the model, but it was a 2 door. Anyways, I was racing him with my `72 240z with stock L24/SU carbs and it seemed like he had a lot more top end than I did. Like if we punched it going around 45mph he would pull away from me, but from a light I could pull a couple cars on him and he would gain it back a little, but by the time we did the 1/4 mile I was still ahead. With a L28 in the little 240 I would probably be able to pull on him at any time if the engine was able to breathe real well. With the added weight of the 280zx body it might be similar to how I ran with my l24 in the 240.. Race'm and let us know.

The igntion trigger is built onto the 280zx turbo's coil mount, which NEEDS TO BE GROUNDED for it to work. It does not pull ground through a wire, it pulls it through chassis. Can use one out of a 300zx, but it wires up slightly different, same idea though. I think it actually has a wire for ground.

If you didn't know, the Turbo XS type H is adjustable with washers. If you didn't get them with your bov then I can get the size for you. Anyways, all you do is drop another washer to set the preload a little stronger and that may fix some issues.

I love her toys I have the 3rd generation supra, the first gen to have it's own body style (not sharing parts from the Celica), and first to have factory turbo (7M-GTE). I'd say it's the heavy one 3650+ pounder. Would love to have the MKIV supra, but my supra doesn't bring much attention by cops and ricers and such. It's almost like having a 2 door Camery, with no one knowing what's under the hood. The silver Z draws a bunch of attention, and has gotten keyed because of it. Lots of ricers rev on me and such. I don't even have the 4 foot wing, or sticker

IMO it's not worth doing the lifter swap unless you have a lot machine work already dumped into the P90A head. Anyways, a properly working P90A head can be a good thing. Cleaning them up with diesel will sometimes help. Could always pull a spare set out of a junk yard for insurance, and maybe some of those would be good.

Ever notice how the stock AFM door gets slammed closed hard if there is no BOV? Man, that's anoying. I've seen the BOV's installed on both sides of the intercooler. I'm not sure which side is best. Probably have seen more installed on the cool side, where the air is more compact.

Boy, my ears are ringing I picked up my tranny for $200 + shipping, then had to get a clutch and resurface the flywheel. My JDM engine didn't come with accesories, but came with injectors, manifolds and turbo for about the same price. Replace the timing belt, as the engine has been sitting for a long time (10+ years). The stock supra EMS is pretty limiting, and is expencive to buy piggy back systems for it. I went for a stand alone system from down under called Wolf3D. There are links to many of these places that I've used on my web page. I would compare the swap as being about the same difficulty as sticking any turbo charged fuel injected engine in that you have to fab up the mounts and driveline for (ie any RB engine or the 2JZ engine). Probably a bit more expencive than your regular fuel injected v8 setup. I think there is more room in the 240Z/280Z to go back with the engine. Take a look at some engine pics and I think you will see. This may mean that you have to go up a little further with the shifter.

I'm pretty sure it gets warm where you're at. An A/C system seems like it would be nice. A good quality muffler, and good door seals to keep sound down. Maybe adjustable shocks (but I don't have personal experience with them). A leather wrapped steering wheel would be nice. Make sure the car seals up well, so that none of those fumes get in. Like replacing the seals around the rear lights, and tank eveporation lines.

Here's the deal, my significant other is cool with me putting money into the cars. She would rather I just have a large amount of power in a heavier car than the Z car for safty reasons. Also, She really likes the comforts of the Supra, which is roomy, quiet, and has a smooth ride. Quite the oposite of the light 240z with tokico suspention, and very little sound dampening material. I've got this engine management system, 7M-GTE engine with header/t4 turbo/larger injectors, HKS FMIC, 5 speed tranny with TRD clutch in the Z car right now. Still no exhaust system, and no drive line made up, basicly just mounts. The engine would slip right into the Supra, obviously. I'd like to keep a fast car in the family, and since the Z car doesn't sit more than 2 I'm afraid I might have to loose it as soon as I have kids. The supra on the other hand sits 4. Also, the surpa already has room for larger tires, has a strong LSD diff in it, already has good sized disk brakes all around, has ABS, PS, A/C, etc. Do I stick the low mileage 7m-gte into the supra or finish it off in the Z and risk loosing my setup after a baby comes into the family. Keep in mind the woman might be more supportive about more mods if she likes the car as well. If I let the Z car go maybe one of you would like the engine that is currently in the supra (has 115K miles with new head gasket), to finish up the project. - OR -

It'll still be damn loud, just a different loud. Kinda like a jet taking off with a low rummble. Add a loud BOV ontop of that and you'll be getting more attention than now.

Welcome! It's a custom job unfortunately. Very nice work, I've seen the car in person and love the styling as well.
