Some decisions were made, a b230ft 13c in good condition got bought, a stock 90+ manifold is in the works and a set of chinabay intercooler tubes have been ordered.

I'll create the best 2 13c's possible from the parts and sell off the worn spare for someones turbojet engine project on the cheap

I also got the generous offer of a cheap 18t upgrade so I might send off one of these 13c's to receive that. For now I'll just get the engine in the car and a turbo tune going, to later still possibly switch to some sort of sequential TT setup. I'm done with the whole 'slow' car and engine on the stand deal

Nice work Swedbrick, "ik kom graag eens buurten om te oh'en" ;P

Cheers

I just got my old 13c rebuild put together with the best parts, and the second one sold. I also got a spare 13c compressor housing, got it turned to an 18T with a fresh core thanks to TurboDutch


The perfect sleeper turbo


I fitted the straight bigger housing from a well used second hand 13g turbo, which was pretty terrible but crack free, should fit perfectly to the planned 3 inch exhaust system


A crack free 90+ mani has also been obtained, the plan for now is to go 13c up until 1 bar, and after a set of bigger 630cc deka's put on the 18t and start the fun!


My cheap 3 inch throttle elbow also arrived which will be added to the k-jet manifold, if my friend with the welder is still willing after I get the intercooler piping made up for the chinese special

At least for now, the engine has been sitting for too long, getting it in the car and running should get me exited enough to try again at some point hopefully

Finally some more progress on this, firstly, the twin turbo will be continued, but not by me The manifolds got shipped to canada to TentShedTrev, as he seems the most suitable to finish this, and I realized there is now way to get this legal here without keeping it as a track only car unfortunately. So follow along on his instagram if you want to follow the project further, I will



The stock manifold I'm switching to got sandblasted and painted.



Followed by a temporary oil cooler delete (will install a oil cooler after break-in)



A non-turbo water line and the oil pan received treatement and black paint



After which during the monthly online meetup I installed the turbo



The PCV got sorted through some 3d printing, which will follow in vinyl 303 filament


With my new 3d printer enclosure with fume extraction I should be able to print high quality engineering materials from now on


I also sold off the k-jet manifold and started on the design of a 960 TB adapter setup, which is still in progress, which might get printed or machined as a future mod with a bigger intercooler for the 18T eventually.

Because if it can, I think I may have to revisit my future plans and squeeze a nice little set of ITB's in!
Identical experience with my very nice ITB from UNIK Sweden on my B234FT (see build thread). Misleaded by the looks of it. Hard to tune/map on the bench because of the on-off effect the ITB’s produced on a turbo engine. ITB’s are better suited for NA engines, I was told afterwards. Have switched to nice 16V KL Racing manifold with Chrysler E-gas TB. Works way better on my engine.

Very nice idea this setup, I wil copycat that. I've been thinking for ages for how to do this in a need way. The thing I like is the less hassle of tubing when working this way.

Interesting, well, for now they are stil on the shelf, I will end up with two b230 engines (turbo and na), so maybe I'll move the N/A one on to a volvo 360 chassis with ITB's, if I can still find one Possibly when I move to the 18T I'll look at the KL manifold.

Yes, for the cap I had to get a L shaped hose from the amazon, which was a bit of a search, the rest is pretty simple. The 3d print simply adapts a generic chines catch can to original mounting, I embedded a adapter fitting in the print so I can clamp the thread properly

My "budget" setup is like diy ported head with orig. valves, diy tubular exhaust manifold and a used hx35 super. Those cost around 400€, then we need only a camshaft, in here, finland we have speedshops which grind new camshafts from example vx3 or an a camshaft, so the "blank" cost around 80€ and regrind cost about 100€, so it adds up to 580€, then you had to open the engine and replace all bearings and piston rings, this will cost something about 200€, then you had an engine which produces 350hp at the wheels and are actually like a new engine, and it cost only about 800€.

But i made an assumption that you can weld and you have access to cheap camshafts and cheap regrinds. I dont know what tohse cost in u.s but there, next to sweden those camshafts are very cheap and very plentiful.

You need and manifold like this, this is and diy manifold welded by mig and tig, this is what i bought, this is not welded by me. But if you had welding machine and little of skill, then you can do this kind of twin scroll manifold by yourself:

Well this tread is mostly my own progress and approach, with all the scope creep involved, rather than a tutorial on a cheap build. The welding isn't a big concern, if your read back a couple of pages;)

New cams that don't require additional shims are roughly around 250eu around here, and given that I added chinese rods, a wider timingbelt with 16v camgears and some better headbolts and springs in the mix, it's not that far away from your 580eu rebuild estimate without the goodies. The upcoming freshly 18T turbo was a custom one off, which including the manifold was roughly double your used HX35 estimate, but that one does work as direct swap, without moving away from the reliable factory cast manifold.

I'm looking for something that works on track with a wide powerband, that teaches me all there is to learn from it when rebuilding turbo's engines and all, and something that will remain legal without too much hassle

Default Last update!

As the engine is now in the car and running, this will be the last update here, the rest will be in the chassis thread

I started off somewhere last month getting the last bits painted


And installed


Finally figured out the mystery fitting, a hose barb at 45° threaded with M14 and a 8mm hose connection I bought from a diesel specialist.


I also got a second pressure regulator setup, so I could swap it all over at the same time and keep the old engine as complete as possible.


The crankcase ventilation received another revision, including an o-ring seal.


With the design finalized I got ready to print my vinyl303 version, all extraction fans in the enclosure and a ffp3 mask required, since high amounts of chlorine gas were emitted


Before cleanup


After cleanup


And installed, I did a few oil and heat tests on the solid print, and it held up, so it should last quite a while


Last look at the maxspeeding rods and the custom oil transfer tube


A little silicon on the edges of the front and rear cover seals


And the pan is on


Ready for installation!


The progress continues from here

Live and learn, luckily a scrapyard had a genuine bosch left over, online they are all sold out currently. It would be a shame if bosch stopped production on these, even the -204 code substitute is no longer to be found

What did you use for the oil filter fitting on the adapter with oil cooler delete? I'd like to do the same.

I used a N/A b230 oil nipple, after making a bit of clearance with a step drill, only a bit of the thread had to be removed to make the unthreaded section fit, so it would not interfere with the filter.

I used this one:
