Hi Craig , Ben here just letting you know you can't hurt your gearbox by having your clutch pedal pre-loaded you will only hurt your clutch/release bearing , swap your series 1 gearbox out for a series 2 gearbox

The drain/fill holes are on the passenger side of the box.
Bottom to drain top to fill and takes just under 2L from memory

Would anyone know if the pivot ball mount for the clutch forks are interchangeable
(ie: rx4/5 into rx7 Series 1/2 boxes) ..?

i need a new one for my series 1 box - or do Mazda still sell them.?

This has been bugging me for a while so thought I'd ask. I've got an 121/RX5 box with RX5 extension housing in my series 1 RX7. Shifting in to 5th and reverse brings the gearknob very close to the steering wheel. Is there another shifter I can use or should I just bend it slightly?

bend it slightly may be your best bet

my memory is vague on the specifics now but im sure at one pint i used a piston 4 spd stick
with a new notch cut on other side for the location pin to get around the uber long rx2/4stick
( only years later did i twig to just moving the pin to other side of turret )

something in memory is also suggesting i ran with the little kinked s1 rx7 stick

though i know for certain that you have to check the length between the two balls as some sticks in the rx4/5 box will fall out of the cup when you reach reverse

I'm using a box 626 one that I got from a wrecking yard on mine. Perfect for my car at least.

i have just changed my RX2 12a twin dizzy to the RX4 bell housing with bottom mount for starter motor to suit the new fly wheel, now as expected the standard RX2 box is twisted, is the RX4 rear gearbox housing the only option to correct the twist?
it has twisted so much that i will need to cut the floor and bend the shifter, really want to avoid cutting the floor...

Can anyone tell me what this box is?

I pulled it out of a series 5 RX7 that was meant to have the 13b turbo I bought bolted to it....???

Have been told it's likely a series 4 12a N/A box..

slight correction there. My suggestion was that it was a series 4 13B N/A box - off the 6 port 110kw engine - 1986-1988 model year. dazz, rota_motor or bumpstart will definitely know the answer.

Haha you're everywhere! Not doubting you, it's just that I'm not going to use it following what you guys have told me today, so need to sell it. Best selling it knowing exactly what it is firstly. I got a bunch of random new clutch n pressure plates with no real part# on them that I've gotta work out too :-"

that's what I thought initially but check out the FC crossmember. Unless it was modified to take the Y-shaped gearbox mount.
