Project Boost - BSDD Style

[Uncle Arthur]

Well - Max is on her way towards boost.

I've already posted the engine bay bling prelim pics (polished turbo manifold etc).

Well - a bit of EBay and a bit of birthday pressies, and the interior 'monitoring' stage is set up in anticipation.....







It was interesting feeding the vacuum hose and oil temp sensor wire through the firewall - there's a big grommet near the top of the firewall which I have poked wire through previously, but the vacuum hose is a bit bigger than a wire. Heating up a screwdriver with a pen butane torch made the perfect tool.

Last week I had the turbo housing 'clocked' 180 deg so the oil drain now points down (turbo was originally a bottom mount, now going top mount), and I'm ordering a few bits and pieces to allow me to fit it sooner than later.....

Oil lines are next, followed by a fitting plate from the US (EBay) that sandwiches between the oil filter and block. It screws onto the oil filter fitting, and allows for an additional three oil accessories - feedline and temp plus another to be fitted without T pieces and the like. Pics here.....





I love projects

Hey Uncle, that oil adapter you picture is available through Just Jap for $30......great quality too!

[sabretooth]

Cool, coming along nicely. The middle plate is a great idea - does it make the oil filter any harder to remove?

Weren't you after another Autometer cup for the other gauges?

Dont mean to hijack, but can that adapter plate be used to feed an oil cooler??

[CT]

Nope - you need a MOCAL one with a thermostat for feeding a cooler - this one is just for additional sensors. I run a 30psi warning sensor and an electrical guage sender off one. There is plenty of room to remove the oil filter with both adapter plates fitted. Could even fit a relocation plate if required but it's not something I care for.

BUGGA!!!! I did a google search of Australian online stores looking for a similar product here and all I could find were yukky cast copies. I paid $30 US plus postage not knowing that this was available locally.

while your looking for parts

dont worry bout trying to fit the S5 IC go straight to what you really want for a good $$!

exact dims as mine and fits perfectly!
and looks cool

btw I might have to get some more gauges! your catching up!

Sorry Uncle... ...I just happened to ask them about one and voila - it appeared in front of me.

Thanks for the info CT. Could come in handy for a future oil cooler project.

Flyin Miata's kit uses the Mocal one FTW

Hey Uncle,

So are going to run your turbo oil feed off of that adapter plate?? Would there be any problem's doing it that way?? How are you going to run your return?

sorry for all the Q's, just interested..

[Uncle Arthur]

Turbo oil feed will come off that plate - as will the oil temp sensor. Oil return will go back to a tap in the sump as per Juffa, LM, etc.....

The mob in the US I'm getting the plate through also do a similar bit of kit for attaching an oil cooler or relocation kit. It's a bit more expensive, but is done in blue anodised alloy. Looks a bit schmick.

(Have a look at the image properties in the pics above - will probably give you the EBay store site)

Why run the oil feed line from there? That's going to result in a pretty long feed line as you run it around the block to the turbo itself.

Running it from there actually at the suggestion of LowMiata...

If you are taking oil from the filter pickup, it
- has been filtered (good for turbo)
- is at max pressure (guaranteed flow)
- is easy to access (not like the hose pickup behind the exhaust.

A long oil line isn't a problem in my books - and it can be easily routed along the firewall - away from heat generation areas.

[sabretooth]

I'm pretty dubious of those points.

All of the oil circulation in the block is filtered - if it weren't then you'd be pretty screwed - mains bearings, big end bearings, oil squirters, camshafts etc etc all receive this oil, and if you're pumping unfiltered oil into those then you'll have more to worry about than your turbo. Bearings undergoing such loads as those the crankshaft is under won't take too kindly to metal filings and will quickly result in a stuffed engine.

Pressure also is not a problem - there is sufficient pressure there as I found out one day when diagnosing my oil pressure issues a while back when I unscrewed the feed to check my oil pump. When the pump's bypass valve was stuck the oil would just ebb, but after fixing it even just when cranking it flowed out readily. If you have a look at the top of the turbo you'll notice a restrictor on the feed. It's tiny, and greatly restricts the amount of oil that goes to the centre housing. If you've ever forgotten to replace the oil return hose, you'll notice that you only get a dribble of oil out of the turbo.

I guess easy access comes down to design of the manifold. My dump pipe goes straight down and I can easily get a spanner and ratchet down there.

But, up to you I suppose! It's good enough for Mazda to use as the factory turbo oil feed on a production car.
