Build thread for MOZDA

I would pull the pistons and clean the ring groves and rings really good. I soak the pistons in acetone or lacquer thinner for a few days, periodically brushing off the carbon with a firm bristled nylon brush. Then, after all the heavy carbon is gone, soak and wash them in hot (almost boiling hot) water with dish soap, using a firm toothbrush to clean the ring grooves. You can reuse the rings, I did with my latest b6t, and it runs excellent. In fact, I have had better results with these used rings than I did with brand new aftermarket rings.

Be sure to keep track of which piston/rings went in which cylinder and make sure to instal the rings with the same side facing up that you took them out.

Piston rings rely on the combustion gasses getting behind them and pushing them outward to seal. If there is carbon buildup (and there will be) in your ring grooves then the rings wont seal properly. Try to clean the pistons without removing any metal from them, especially in the ring groves.

I did the compressed air thing already. Seems to have worked. I've put it all back together except for the head and water pump.

But my gut is telling me to strip it bare and check the rings and oil pump seal.

Go with a soak in water and let the pieces drop out the bottom when you pull the block then use the compressed air. Or turn the block upside down and blow air up into the channels.

Pulled my engine down to the block this weekend.

Turns out the guy who sold it to me was telling the truth (I didn't want to rely on biased opinions).
The bores are all shiny and new looking. The bore patterns are spot on and untouched. There is no ridge above the rings, so I'd say this motor has less than 60,000 km on it.

There is a buttload of carbon build up:



But its nothing a bit of elbow grease won't fix



As you all can see, the head gasket was pretty well stuck on.
I managed to clean it all up real nice [INSERT PHOTO] but some of the bits of gasket have gone down the oil and water jackets.

I'm gonna remove the sump and blow all oil jackets out with compressed air.
Is that what is normally done in this case?

Thanks wolf! Love the encouragement.

And lastly (for today). I made shifter bushes out copper tube.



I also installed my civic short shifter, but I didn't take any pics yet.

The other thing I got done today was my gear shifter linkages







Once again. Having a bad day with my arc welder. But bit did the job.

I know how much you guys like pictorials, so here are some pics of my modded mounts.

Front gearbox mount bracket below. Made from scratch with angle iron and some flat bar.
My mig has been playing up, and I ran out of argon for tig. So I resorted to my good old arc.
Hence the ugly looking welds. Haven't arc welded in ages and I'm very rusty to say the least.







Below is how it looks mounted.



And here you can see the lower profile you get with the 1996-2002 DW 121 (demio) mount. Approx 35mm lower than the festiva mount.



Rear mount below:

Before and after






Mounted below:

You can see the clearance with the steering column. Pretty darn tight.

Been neglecting my build and build thread for a while now.
Life seems to keep happening and leaves me little or no time to tinker.


Anyway. I've finally have the B6T sitting in the bay.
2 of 3 mounts are done.
I'm making the 3rd mount as I type this.

The timing belt side mount is the standard b3 mount with spacers, the rear mount is a modded Capri g series mount, and the front is a DW Mazda 121 mount with a custom made bracket.

Best piece of advice I got was to lower the rear of the cross member by an inch. Made a world of difference.

It took me like 20 attempts to get it to line up how it does now. But its well worth it. This is bound to be the first B6T DA Mazda 121 in australia (as far as I'm aware). I can't help but smile when I think of that.

OOOOK!!! so my project has been in hiatus for a few months.

The car has been on stands for 2 months now. Ive got the aspire rear end in but the drums seem to be seized up hmmmmmm

Even though that is definitely on my to do list. My main concern was the previously mentioned brake booster and master cylinder issue.
I may have mentioned it earlier how i was planning to mod a MAZDA PROTEGE brake booster and MC to make it fit the car and create some more clearance for the DOHC motor to fit.

Well, as i found out, the protege mc was still a bit too long and i needed that extra bit of clearance. So i tried on a kia rio MC and even though the pushrod didnt exactly line up, I managed to modify the booster to make it all fit rather nicely.

####NOW BEFORE YOU READ ANY FURTHER####
THIS IS COMPLETELY EXPERIMENTAL, I HAVENT HAD THE CHANCE TO TEST THIS MODS OPERATION. SO ANYONE COPYING THIS IS DOING SO AT THEIR OWN RISK.

This is by no means groundbreaking. Im just so happy with the result that I thought I'd share.

You'll also get to see the guest apprearance by my B6T who is getting quite comfortable in the engine bay. Im sure you guys will notice how tight this swap is when working with a Right hand drive car.

Looking good mate...

Are you going spruce up the Mazda engine bay and give yourself a bit more inspiration or just mount it in?

Any ideas for a colour theme or is it going in as raw as it would coming out of a $2 hooker?

These thoughts need to be considered, as I can see, your motivation will make this rocket shine and overall, be able to pull up ashphalt from a stop start .

Re: Build thread for MOZDA

I'll be making some metal washers for top and bottom. Top to spread weight evenly. Bottom to prevent the perch on the shaft from biting into the Teflon.
