As I expected, turbo shop couldn't find matching BB CHRA for this turbo. Ended up buying Precision 6262 BB. As always, money spent on cheaper alternatives will eventually be just the money thrown away.

I reused stock CT26 WG actuator with additional spring pulling back the WG to make it stiffer, so it started to open at 15 PSI if I remember correctly, but that didn't help much with the turbo lag. I have a manual boost controller, so either exhaust gas pressure is opening the WG or the turbo...

Nope. I was hitting rev limiter all the time if not looking at rev counter.

Mine is pouring oil as well. It had happened before and then it turned out the oil drain was clogged (bad quality hose close to exhaust manifold). I changed the drain hose to teflon (plus rebuilt the turbo even though it was almost new) and it was fine until it started to smoke again. And it's...

A little update since I've started posting here. As mentioned turbo is fine, but it 100% was leaking through seals. It could be clearly seen as both sides were in oil and exhaust manifold and the exhaust entrance of the turbo was dry. I went back to workshop and they tested it took it apart...

Ok, I think I spread misinformation on the turbo. I got the rebuilt turbo from the workshop, installed it according to the instructions they gave, and nothing's changed (except the money in the pocket) - smoke all over the street. It could be a lot of things causing that and clearly it isn't the...

Here's my experience with the turbo. I fixed all the issues mentioned in the thread, reused the WG from stock CT26 as it seemed to have a stiffer spring. Turned the boost up to 20-24PSI. The full boost comes late - about 4k RPM, but it's significantly more power than CT26 and it doesn't stop...

A lot of good info here. I bought the turbo and going to fix the known issues, but one thing I didn't see discussed is a brace for this turbo (like for CT-26). I think it's important as this turbo is heavier than CT-26. Has anyone made one for this turbo?

I would say - don't think about those dreams. The more you think, the more this idea of UFO get's into your brain. If you cannot do that, you might want to investigate and find out that there's no bases for UFO claims and it's complete BS. If you know what is a scientific method, then you can...

Thank you, exactly the answers I was hoping to get :). What about the pressure numbers? It depends on the setup, but how much pressure gain did you get with thicker oil? Or maybe it was compensated by wider clearances...

I've read all the info on oil in SM (including Motor Oil 101 - Dr AE Haas), but I'm still not confident which viscosity oil to use after the break in. I understand the flow vs pressure thing and the benefits of lower viscosity, so I'm not going to argue about that. I've also read that it's...

Yeah, I already realized the first one is not for our engines :). (actually I don't think it's wrong because of that, but probably the deck clearance). I'm more interested if everything's fine in my last post.

could somebody confirm/correct that ^ ?

hmm... yes, it seems to be calculator for Honda engines... it wouldn't matter if Piston-to-deck Height wasn't calculated as -0.010 (don't know mm or in) for my engine (as IJ said it's already 20 thou out). Ok, tried another one: http://www.csgnetwork.com/compcalc.html If I'm right, the...

I used this calculator to determine CR: http://www.zealautowerks.com/ I've got over sized JE pistons, eagle rods and total amount taken from head and block decks together is 0.5mm (0.0197"). Could someone check if I entered correct numbers (in attachments)? And which one of HG thickness...
