I have DLC'd the tool steel lifters from Thorsten, so the lifters are the least of my worries
Personally I would like to see how the pistons are wrt skirts in relation to the clearance they had and of course the head seal

Nice one Wally! Did you put rope inside the cylinder to hold the valve or did you use air pressure?

Great idea with the jubilee clips, that would made it much easier for me if I had thought of that!

[Wally]

I used air pressure Paul. Killed an old compression measuring device for that a few years ago

[Wally]

The Berg double springs were about 35% down on spring pressure

Check your springs after about 2 years of driving I'd say...

Anyways, back tp building the twin scroll header:
Trial fitting:

[Frix]

Impressive, as always! How will you route the oil return line, with the turbo that low?

[Wally]

Welcome to the board Frix!

Oil return will run as it was before with the former turbo as its about as high or low as the other one was

Wally,
Check this divided housing fabrication.

Wicked nice welding for sure! Subies/Evo's and Honda's use the twin-scroll set-up a lot.
You're reading ricer forums now?
j/k its a good thing to broadthen (sp?) our minds and apply new (although usually very old) tech to our engines/cars ;-)

I agree!

Walter, what's with Your 1200 turbo engine and will you have thread here on GL forums about build? That downsizing stuff is very popular now

I dunno if that would be a good idea, its not really in the spirit of max performance, though I am very exited about the project it myself tbh . Its slow progress too as it all costs still a lot, even if its type 1.

Meanwhile, some progress on installing/trial fitting the Tial wastegate, trying to outsmart the system by just using one WG by dividing the uppipe
Divided pipe is now visible, of course needs to be shortenend and connected to both up pipes to turbine.




New wider pipe to the intercooler fits well too now, almost straight shot from the turbo

Looks like it´s getting tight in there now I suppose there´s no way of locating the WG further upstream?

Just for the WG there would be room upstream just under the rear valence right after the 4-2 sections, but I saw no routing of the neccesary slicencer anymore then.

[NO_H2O]

Getting close. I look forward to some new videos.

[Wally]

Yeah, coming saturday I hope to get the oil return outlet for the turbo and have the flange machined flat again as it has warped a bit after my welding...
Still the main downpipe silencer is not here yet and that needs lots of modifying too. Lots of work still.
