zx beast

Your z is beautifull by the way mr jc 05... But anyways, I have been told repeatedly from kids at school (never a good source) but they say running a straight header is bad for your car, because I backfire sometimes, and that is bad for the valves. Is that true? Will running a straight header kill my car? And do you think I could fix alittle of the back fire problem with new high performance sparkplugs, and or wires, and or coil? To reduce the amount of unburnt fuel by burning more is what I was thinking...

I am now running straight headers... lol and the fumes kinda suck, but I like the sound lol I feel a differance when I get past four thousand rpm, but I feel a power slump between two thousand five hundred, and three thousand... So I think it is no good for top end. But when I really get on it, I do notice a differance in how long I do not have traction (I can't hear myself burn rubber now though... exhaust is too loud)

Actually, my heater works just as well as it used to, which is really really good. I have a bunch of holes in my car, and it still gets very warm, very quick.

I have to do the same thing. All I know forsure is that Black dragon auto is very overpriced, and maybe you would have better luck at a junk yard. That is my plan.

You don't have to buy the valve, you can just pick up a 3 way from autozone for like a couple bucks. I was having the same problem with mine leaking, and also couldn't find a new one.

I am running 20w50 in my car, and when the car is ideling the pressure is about 50psi, and when I get on it it goes up to 75 or 80. but the pressure def isnt low because the 20w50

Hey, so I am thinking my speedo is about 10mph fast... so I was wondering if anyone has a 130mph speedo they are willing to let go for cheap, or if someone else has already put one in, if they have the stock one laying around if they would be willing to let it go for real cheap. Or is there an easy way to fix mine? Thanks.

can I put a turbo sized flywheel and clutch plate on my 81 na, or would I have to do a t5 swap? My clutch is slippin pretty bad when I get on it, it is prob stock after the last 28 years... lol

hey, I am in copperas cove tx, and lookin for some lsd... if I were to drive down there, how much would it cost to pick up a lsd... I have an 81 zx na... what is the best gear ratio???

So, what would you have to do to put a T5 into a NA 81 zx?

if you have water on the front of your block it is prob from a bad thermostat gaskett, just fixed the prob myself

So, I bought my little 280zx, and have bought headers, intake, and exhaust for it, but think if I tune the car alittle, I could squeeze some more power out of it... but I don't know how to do any electronic work... or anything... How can I tune my car for more power?

How much would a dash cost me?

He is right about the header wrap, and I think you do need the washers... or at least you "should" use them... They make up for the space differance between the flange of the header since it is a differant size... It goes on the top bolts of the header where it overlaps with the intake.

So amond many other problems, lol, everytime I depress my clutch pedal, there are 3 clicking noises... I read on someones v8 post that there scarab doese the same because a mount is broke... Does anyone have another diagnosis? And where is this mount he is talking about? Sorry for newbishness, but I am kinda at a loss...

Go to dragtimes.com. It is a cool website where everyone puts there dragtimes down in comparison with other cars, and they can also sell parts there. I found so many parts for so cheap, including nismo headers for only like $30... And s30 fender mirrors for $15... it was awhile back, but check it out. Just type in a search for 280zx, go to a persons profile, and on his profile it will say parts for this car. Click that. It is super sick, and there is ALOT on there.

sadly, I have this header. If it is cheap, go for it... I bought mine new, and there was no pipe for the egr attachment, so we had to custom fab some. Also it requires special washers that come with it, so I don't know if it will work without them. From factory they claim up to a 6 horsepower gain.... wish I wouldn't have spent so much money on six horsepower, but they sound is alot better. Also the gaskett that comes with it isn't good, you should get a felpro one. The paint doesn't last more than 10 minutes, so maybe you should paint it with header paint, and wrap it, although if you wrap it it will be EXTREAMELY hard to put on, especially if you do not pull the motor. But your life will be so much easier if you can pull the motor, I had a heck of a time. Also remember you can get to the top overlapping bold by removing the plate on the intake manifold, wish I woulda known that, but it only helps if you are not replacing the gasket. Hope I helped.

I am interested, what state are you in? I am kinda poor and cheap... would like $50 be ok?

I AM INTERESTED! But cheap, I bought my zx for $850 lol Super beast. None of the pics are working though...

If you can make nice fiberglass peice you could sell them. I dumped alot of weight with ac delete, and bumpers, and interior. I would be very very interested if you made fiberglass fenders/ hood/ custom lip

So, do I want backpresure? Or not? I don't care about how loud, purely performance. I have the flowmasters, and if they have to much backpressure, I will hack it off. lol I mean, how would 2 inch exhaust compair to 2.25 manderel bent with a muffler? About the same? Or would I not have enough power and loose low end torque?

The 81 turbo has that hood, and does have those wheels, as well as a 5 speed transmision, same as the non turbo. 79 and 80 had a 5 speed, but fifth gear was forked with reverse, and was not good, but 81 and up was all true 5 speed. But yes, from the looks of it, that is an 81 turbo.

It is way easy. I did it because I couldn't find any tail lights for my 81 for under like 300, so I got some from an 82. Bolt right up, but I want some old 81 ones back, I like the look better... But it is easy

Will wheel that fit on a honda fit on a z? they are both 4 by 100, and look to be about the same... will it work? It is easier to find honda wheels lol:grin:

So, I have a 1981 280zx with k&n cold air intake, pacesetter monza header, and a flowmaster muffler... How much backpressure do I need? Would I gain power and or torque with straight pipes? I think I have about 2 inch tubing...
