Rb25de (supercharged) Project

[Mister25t]

Choice, been watching out for an update on this.

The manifold is looking nice all ceramic coated. Looks really tidy from what I can see.

Very clean job on the wastegate inlet off the turbine housing too. Have seen some butcherous jobs on those before.

Haha, that side of the engine bay is going to be packed as when it's all assembled.

Glad you are still working on this. It's been a while in the making but I'm sure it'll be worth it as soon as you can give it that first squirt eh. Bring on the chubby ass power curve.

Yeh the manifold is not too shabby. If I had spent more time planning it out It could have been done a little better, but its going to have to do. If i was doing it again I would change the merge angle of the collector so its closer to ideal around the 10-15 degree marge rather then the 25-30 degree its at now. I was worried about it being too close to the bonnet, but it appears to be further away then expected. Live and learn.

I can say when its all in and going there literally wont be room for anything, at all.

Certainly has been a long time. But its getting there. Im hoping for the same thing!

Coming along very nicely.

How are you going for room for everything?

[r33_racer]

Lol there should be enough room for everything I need, I think. It is going to be a little tight where the outlet of the turbo goes into the charger inlet though. I will cross that bridge when I get to it But its very safe to assume the engine bay will look full!

The dump pipe is nearly there! Lobster back central in this bitch.

Everyone likes lobster right? Nice one Mike

[Craved]

Looking sweet!

was that cone hard to source?

[Madaz]

awesome work there

[r33_racer]

Lobster backs ftw Mike!

Chris, I was given that one, however im told you can get them from a company called Midway Metals. MIght be a good place to check if you are in need.

Thanks mate. Hopefully Ill have it finished and fully welded tomorrow, ready to bolt up!

Needs more pics Mick

Great Work Michael,

Hope you will PRUGE DUMP when you weld it,

save you having to do any GRINDING inside,

[r33_racer]

Lol yeh I should have purged it, but I was too lazy to machine up some bungs. I seem to like doing things the hard way lol. If I was doing this all at work then I would have as material and machines would be there. But its done now.

Took forever to weld it.....stupid lobster backs.

Hopefully have wastegate outlet finished tomorrow night.

Love the step at the end.

Goes back to 3" or 3.5"?

[r33_racer]

Its steps back down to 3" to match up with the existing system I made when it was just supercharged. I didnt really wanna fork out for more mufflers and redo the whole system in 4". This will have to do!

Its not an ideal step down either, its a 60 degree step rather then the proper 15 degrees or whatever its supposed to be. The first expander is more like what it should be.

It's a tube reducer. You can get them concentric and eccentric. Available in 304 or 316L

Lobster backs ftw Mike!

I used to order mine through M&S Stainless in Prospect; http://msstainless.com.au/

Been following your thread for a while now; fantastic work, amazing!

Excuse my intrusion; back to the show!

Cheers mate.

Well wastegate outlet is all tacked up, ran out of time to weld it. Lol no pictures sorry. However I have spent the last 3 hrs at work this morning working on the charger intake flange to accept a 3" tube to hook up the turbo outlet. Starting to take shape, Its going to be tight getting the turbo outlet plumbed into the charger intake though .

Got any pics to show how close the two are together?

[r33_racer]

I have one but its on an angle. Hopefully will give you an idea though. I think from memory it was 75mm or thereabouts.

[zebra]

That is rather toight!

[Sir Lord Van Von Vader'ham]

might be a silly question, but why did you make it go to 4in in the first place?
