I got tired of looking an my old pod filter and decided to fit back the stock air box and filter. I turned it upside down and bolted it to the chassis.

Fabbed up a cover that fits under the hood with the air opening at the front next to the headlight. (Used some prepainted roof flashing for cover.)

Hopefully the stock filter element will boost power, eliminate knock, increase my social standing, give better gas milage, etc.

Hi Sturovo,
Love your flowish manifold and downpipe elbow.
Live in the Netherlands and have a 1.6 mx5 year 2000.
If you start to make kids for the subbi turbo mail me a price and maybe I am your first costumer.Have a td035 turbo off a forester laying in my barn,for just a little bit more fun.

Thanks Dick, I am glad you like it!
I am working on a 1999 1.6 setup now which should also suit your car I think. I will send you the details.
I was doing some further kit testing today on my mobile test bed
Later I added back a few degrees at 6.5k to cure the missfire.

Meanwhile I test fitted another setup to a 1.6NB. The ps hose is closer on NB than NA but It is possible to rotate it with a custom backing clamp. Importantly the compressor outlet clears coolant hose and there is plenty of room between turbo and frame rail.

Also plenty of room on exhaust side for 70mm downpipe. (Heater hose is loose in picture so less clearance than actual.)

Just curious if people use flexible stainless piping for oil drains?

It seems like a decent alternative to rubber hose as it is tough when connected and there is only ever going to be minimal relative movement of the ends. It is easy to substitute 3/8, 1/2 or metric fittings for the bung connection which should make finding taps easier.

Thoughts, has anyone tried this?

I made a turbo manifold and downpipe for an NA engined Exocet!
After looking at the project/car/specs I realized that that a kit car is on the cards. (Hopefully soon)

I increased the downpipe outlet to use 60mm piping (versus previous 55) at the exit and included a 60 to 75 mm expansion section. This allows the set up to be tied into the stock exhaust or a 3 inch exhaust.

Cool parts! I'm sure that drain line would work, but what's wrong with a straight piece of silicone? That's what I used and it is awesome.
I really like those hot parts though, good job. Anyone run a vf39 on a BP yet?

vf39's are pretty rare, I am curious about the china knock offs. How would these hold up? New TD05 TD05H 20G Turbo Turbocharger for 02-06 Subaru Impreza WRX STI EJ20 EJ25 | eBay

I made a setup for a 1.6 NB.
![](https://www.miataturbo.net/attachments/diy-turbo-discussion-14/82853-td04-td05-fitted-place-t25-t28-p1030787_zps393315be.jpg?dateline=1374162545)
The downpipe goes from 70mm at the turbo outlet back to a divided 2 x 44mm to match the exhaust. (It should be possible to chop off the merge and join it to a 3 inch exhaust as a future upgrade path if needed.)

I used heavy wall boiler steel bends for the manifold as seen in the photo. (These are 4mm + thick so should be track durable.)
A divided merge and short clean runners should make for good spool and flow characteristics.

Now that I have figured out NA and NB it is time for NC.
