These are stainless swivel fittings. There a bunch of different tubing sizes and materials. Same for the fittings. Got the idea from the green brother's 323 wagon were using them on there water Inj setup. I'm using nylon tubing as it's good for 300psi but has much higher temp threshold then other materials. I'm using for Wastegate solenoid and water inj solenoid and fuel pressure reg. So have eliminated all other vacuum ports on mani

 

New tire Tuesday...

Picked up some new Bridgestone Potenza Re003's up front .

Moved my old Dunlop Direzza Dz101's to the rear.

Pretty stoked .

 

Thought I'd chuck up my street alignment settings. Not too aggressive !

 

Some oiling updates!

Finally got my Mazda speed Dry sump after a lengthy 6month, tiresome deal with a forum member.

Don't deal with David Eppinger. 1FaastFD3s




In the time where I thought this Dry Sump wouldn't turn up at all, I ordered this cool gated Wet sump. A definite step up from my Xcessive Alloy sump, which I thinks only advantage is better sealing than the factory sump.








And its final design has a integrated Baffle



And also a Oil pick up sandwhich plate to lower the pick up tube to the bottom of the deeper pan.

Sprang a leak in the weekend,

Heard a little fizzing after shut down, found coolant bubbling from between the centre plate and front rotor housing near the primary injectors. Im now in the process of pulling the engine, going to check the torque of the engine bolts first.I haven't re torqued since the initial build.... Hoping for the best.

 

Do you have a cap of some sort on the side of the water pump housing(facing turbo). There is another coolant steel hose barb here( oem tt return) and my guess is this is where it came from looking at photos.

 

Thats was an older issue about month before this thats why theres some/alot spray to the left there. But it was definitely bubbling from the housing gap and filled the recess in there with a pool of coolant.

 

Little Garage **** ..

Ready to pull our engines for some winter maintenance.

Doing quite a lot on mine, and Non sequential conversion plus hopefully a Greddy Vmount on my flatmates Joshs red rx7.

 

Pulled my engine this week for some upgrades,

Mainly to upgrade the wastage lines and fix the oil loop line leak and heat shield both.

I posted i had upgraded the lines previously but i never got to replacing the rear wastage lines, with the engine out it was a perfect opportunity.



Starting with the rear , i used silicon double layer and inner braided hose wrapped with heat shield separately then again half way and another layer combining the two lines.



On the front I used a rubber inner braided line and used some high temp silicon over the top.




Now some random garage pics haha



Thats it for now ...

 

Hey nice build , specially work , that oil loop line leak your have, are you able to elaborate about it .

I'm currently doing the "oil mods" , the direct front bearing and return on front iron now have -8orb fitting, just wondering if that's what your talking bout.

 

Thanks

Ah i didn't mean a true loop line, i was referring to the oil vent line from the exhaust side if the engine back to the catch can and filler neck . Sorry! It totally burnt thru the braided line and ill be repairing and heatsheilding that in a post tonight !

 

Whoaw eh, how many clicks you did before that line cooked ? I'll have to protect mine

Really well taken care car here
It's nice to follow you.

Ooo about that "full oil loop line"
I believe it will be a mandatory process once you install that dry sump you finally got.

 

Alright Oil vent line protection time !

I burnt thru pretty much right away ...



Something that didn't work initially was using a normal 90 Deg bend , it stuck too far out and was touching the wastage's dump pipe.



So i used one of these instead , its sits much better... and gives a lot more clearance .







Now with the heatsheild , covers over the top of the fitting too.




I thought it would be cool to document this a little bit as its something i haven't seen too much on this forum specifically , and when it / if it burns out could be a very tricky thing to fix on the go (not to mention catch on fire )

 

Tonight's mission... Putting the Heart back in !



So low can't even get the crane underneath without jacking the subframe 😉

 

Some interesting welds on the inside of my watsegate plumb into the exhaust ... What's happened here?

 

WHAT THE ****!? Who sold you that manifold? That is from some sticking mig weld in there, sucking at it, and then not grinding it away.

Absolutely NOT what is supposed to be done.

 

WOW!!! Those are some truly awful welds... I did better than that in 5th grade! Just grind them down.

 

Indeed, pretty shitty

 

So after back to back late nights and all today, i finally got it back together.



But within 2 minutes of starting , it started bellowing white smoke.








It wasn't doing this before i pulled it ... is this common to just occur on an engine sitting for a month ?

Just wanna confirm too, white smoke .. coolant leak?

Better start the pull down

 

Did you change your catch can setup at all? Excessive crank case pressure will push oil into the combustion chamber.

Before you do anything drastic like pulling the engine, check the basics. if you think your burning coolant you will definitely smell it and see your coolant level dropping significantly. A very quick test would be to start the car and take the oil filler cap off and see if the smoke persists. If the excessive smoke was caused by oil it may take a couple minutes after start up to clear up.

 

Thanks for the advice, indeed you were right. I had sealed it off and it had no vent to release any pressure.

It still smoked a little bit but definitely not as much when fully warm, maybe could be deposits on the exhaust and changing to a thinner oil... i usually run thicker.



I prepped the car up to take it for a drive and to get the exhaust nice and warm,
hopefully burn anything out ......but i knocked the Air temp sensor off and broke it

Just my luck haha new one is $60

 

I'm glad it was something simple. Sucks to hear about the intake temp sender.

Im going to be looking for a Version 6 Series 8 2001-2002 or get my hands on a Spirit R if possible.

 

Excellent build! Quick question though, where did you mount your front relay? I've been trying to figure this out to no avail.

 

Thanks man Do you mean The long black fuse box at the front ?
