94DXPRO,

Hey Man! I am the guy Wil referred to. My name is Mike and I to have a 94DX with the slush box. The hold button for drag racing purposes is useful as Wil described it with only one exception. At the start with the shift lever in 1 and the hold button on, you can hold 1st gear till 6250 RPM at which point depressing the Hold button will let the car shift to second. At the track, I never get out of second gear in the 1/4 mile but am at about 6000 RPM at the end of the track. There is really no need to move the shift lever to 2 or D at the end of the track cause it will actually run a slower time. By the way..18.2@75.9 with a .5055 reaction time is all I could muster. I will have it in the high 17's but that's it without a turbo or NOS.

Yeah that hold button lets you 'hold' that gear for everything that it has. I have used the hold button sometimes on my everyday driving just to play with it. It is like having a 4 speed manual. But you have to remember, it is an automatic. The automatic transaxle doesn't like shifting. I was wondering if the shift points you were talking about eariler work for the DOHC (125) engine? As for the new cars, my mom's 2001 626 has a hold button. That 2.0 liter 4 cyl has some *****.

The 94DX's only have an an indicated redline of 6000RPM (you can actually go to 6250 before fuel cutoff in the DX). The shift points for the LX should be higher since I believe the indicated redline shows 7000RPM. I have only driven 1LX Pro (GroHarlem's 5-speed), but not hard enough to find out where the fuel cut-off is. I would assume you would be able to get close to 7250 before fuel cut-off.
I wouldn't recommend doing this to your car on a frequent basis. I only do this when I drag at the track to try to limit the possibility of breaking things since it is also my daily driver. Just FYI, I have been through 2 complete sets of motor mounts. I killed the last set 2 weeks ago when I went drag racing with GroHarlem, so just realize eventually something will give when you rag it.

on my 95 protege S (1.8sohc, manual), the fuel seem to be cut around 6750-6800. In fact, i dont know what it feel on the fuel cut-off, maybe it isn't the fuel that is being cutted, but it doesnt get any higher. pretty annoying... j/k

I know through all the literature I've read and persons I know that have the 95-98, that the 94 was the last year for the 1.8 SOHC (103hp). Mazda switched over to the 1.5 liter DOHC (92hp)and retained the 1.8 DOHC for the ES models. If you have a 1.8L SOHC, you are for certainly not able to rev past 6250RPM unless you had you ECU modified.

I just wanted to add that I have never heard of a 95 Protege "s". So if you boys up north got a special edition us U.S. residents didn't, then this is news to me.

Well in 95 in canada, mazda kept the 1st gen S another years because of i dont know why.. (check earlier topics i posted).
Anyway, can the rev-o-meter be wrong?
I'd switched the cluster with one with a 6000rpm redline (form a Protege SE or LX, i think, (keep in mind canadian LX got sohc)) and i'd actualy pass over 6500 a couple of time.

MikeD

Well I guess I do learn something new everyday! I had no idea they held the 1g body over to the 95 year in Canada. Honestly, Wight I can only speak for the U.S. 1G Protege b/c I've lived with mine for the past 7 years. If you are able to somehow run to 6500RPM or higher, perhaps there was a slight difference in the 1.8Can and US SOHC engines. It wouldn't seem logical that they would engineer such a variance since the goal most times is to have the engines remain consistent for cost-effectiveness. But then again, it seems we get screwed when it comes to the models with any real grunt (e.g. the 323GTR).

What does your car indicate for a redline? You mentioned that you had swapped the instrument cluster from one with a SOHC. Are you absolutely positive you have a 1.8l SOHC and not a DOHC??

Well, as far as know, it is a cluster with a tachymetre form a 94 protege. ( here is the picture of my new cluster
http://wight.multimania.com/images/cars/PROT_09.jpg )
Redline at 6000.
In Canada 1st gen Dx, Lx or Se models have the same engine 1.8sohc " here is the picture of mine: http://wight.multimania.com/images/cars/PROT_08.jpg " so every 1st gen got a sohc, except the GT version (Dohc).
The tachymetre can be wrong, but i really got over 6500 a couple of times, and then hit the cutoff. so that's pretty weird to me.
