I actually think you can buy a billet 19t with the STS turbine in that fitment too.

So... full spool during cranking?

No, the STS turbine is bigger than the L turbine, its actually the same dimensions as the HL turbine, so I'm guessing it'll spool up like the L turbine but flow better than the HL. And of course the 19t comp wheel is a whole boat load bigger than the 12c one.

Might have missed it somewhere in this thread but where are you getting those flexible metal oil drains?
Edit- Also these manifolds are 1.5" pipe or 1.25"?

Most manifolds I make have use a combination of 5/4 for the runners and 6/4 for the merge. I prefer 5/4 for the runners as better vectoring can be achieved. There is a small step where the 2 sizes join unless the 5/4 end is flared before welding. (I guess the step acts similarly to a reversion cone?)



The 5/4 id is less than the gasket / manifold port size so the ends need to get flared a little also. The actual exhaust port size (as opposed to the gasket size) is pretty close to 5/4.



The dual 6/4 merge is a good match for both t2 and subaru 3 bolt flanges.



The oil drains I make myself.
(The stainless tube comes in rolls and it gets cut to length. Tubing is rated for 15 bar and > deg C)
The turbo connection fitting is derived from the first principles of sweat and swearing as it involves 3 holes, threaded pipe, welding, surfacing and gasket in a 1 inch piece.
Why? way to retain the stock coolant line...

Making downpipes is not fun, some kind of endless measure-cut loop

Encouraged by Leafy's talking stuff I went in to a downpipe flat spin and spat out a few more



I added a slip joint as at heart I am not a flexi fan


And a gearbox bolt clamp bracket


And also made a TD05 version


Next up...... NB versions

I have always been under the impression hard mounting an exhaust was/is always a no-no. This is why the OEM's don't and I personally have had a hard mounted exhaust crack/break at the mount.

The stock downpipe is hard mounted to the tranny like he's doing. Unfortunately Bundy says you need a wider band than the one you showed or its still gonna fail in track use.

Nothing wrong with hard mounting as long as its not welded directly to the pipe but rather clamps the pipe like he's doing. OEM's actually do it this way.

Good work Sturovo, your improvement is evident with each iteration

Thanks 18. Several of the changes have been the result of users feedback and suggestions.

Recent stuff...

T25 kit for a 1.6 NA. with a 15mm thick manifold turbo flange tapped for fancy studs.


A t28 manifold for a 1.6 NA with an external waste gate port. The divided merge extends into the waste gate port and hopefully should help flow.


TD04 for a 1.8 NA


And some kits with 70mm downpipes

As many others have said, your work with a stick welder is fantastic! I'm really looking forward to see what you've got coming up next.

This. I'd be interested in a better manifold and down pipe with the bolt pattern on the right.

Ryan, Ben, I appreciate the kind words!

Austin, It is a bit tricky to make a full downpipe without having the matching manifold in hand as a slight twist at the turbo flange can makes a significant difference at the other end. As an alternative a replacement 60 to 70mm downpipe like this one could work.

Ray, I would like to try Thing is that those turbos were never popular where in Slovakia/Europe so getting my hands on one may be difficult.
They were used on DSM's and evo 3's?

Meanwhile I have been working on a few Subaru based NA set ups





decent clearances



and a NB T25
