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.

I mocked up a NB 1.6 set up.



There is space for a 70mm x downpipe as the flange is a few inches aft in comparison to NA's.

Vid looks good, looks like you've got some good torque going on there.

sturovo

Thanks Firendc, I am pleased with the way it runs for a td04-13t non intercoolerfiedification. (And even surprised by the acceleration to redline in 3rd gear and higher.) I will try a td05-16g soon and see how the manifold deals with more flow but my feeling is that it is better than the other manifolds I have tried up to now.

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.)

Hi,
That's looking good.
Found a picture of a oilline on the ILmotorsport site,it a 1.6na but on a 1.6nb it will work also I think.

well look at that! what size is the thread?

sturovo

Good Info Dirk! +1
Scott I think it is is 1/8" npt or the equivalent 1/8 G designated thread. This plug is from my 99 1.8 so the port must be universal?

dick 5322

hi,
I think it's a g1/8

sturovo

Yes you are right, it is not npt but rather bspt which in Europe is designated g. (27 vs 28 tpi, 55 vs 60 thread angle.)

sturovo

I put together a 6mm stainless hardline to connect to the oil port at the back of the engine. It is a more elegant solution than the pressure sender T off IMO.

sturovo

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?

sturovo

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?

The vf would bolt right onto this setup with no extra work.

sturovo

Fireindc, for sure silicone is a great solution for sure but in this case the oil drain was routed around the coolant hose meaning compound bends were needed. Flexible stainless tubing makes it easy. I will probably add lock wire to the fittings.

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 actually have a knockoff subaru 16g waiting to be installed. From what I've read on the subaru forums, its pretty much the same as all chinachargers, hit or miss, but for the most part, pretty decent.

You want the kinugawa branded stuff if getting a "knock off" subaru fitment turbo.

sturovo

I made a setup for a 1.6 NB.


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.
