Looks like aurora plating. IRRC there's only a few companies that will do just a one off for a random person because it has a pretty high chance of scrapping a part compared to anno or other plating/coating.

I like it. I think it's cool, and goes well with what's going on in the engine bay.
Plus i'm sure it would score me a ton of swag points on CR.

the valve cover plating im told was pretty pricey. a new coating job on a vc is ~$500.


The brakes are upgraded already. those are Integra rear discs in the back and i think he has those on the front too....

The rear brakes barely do any work on a civic. most people dont bother upgrading them.
There isnt enough weight in the back of the car to overload those brakes before you start to lock them up from how I understand it.

Not my car though...

Question to schlammed and leafy.

guys how do you weld the those tight collectors to the rest of the manifold, what cups and techniques I always find it very frustrating trying to get the welder in there.

Not that i've ever had to do it. But when i'm challanged with a tight space, i turn the gas up, and pull the tungsten out.

Yeah thats how I did it. But I literally only have a #6 cup, long cap, and 3/32 collet so I didnt have any other options. Having a really sharp tip helps you not have the arc jump off the side of the tungsten.

Optimally I would have used a gas lens and the correct size cup for it with the really short cap.

there is no design options?

or an order you weld in specifically, i always struggle for ages doing it, is this just how everyone in the trade does it?

Some collectors are so short and with such a shallow angle i struggle to see you you can get a nice weld especially on something thin walled like headers.

I use a #6 cup with the argon flow pretty high and a long stickout.

You have to be steady or you will hit the sides.
sharpen the 1/16 tungsten to a fine point.

Running a nice fat bead helps too.

Well a good collector shouldn't be short and have a shallow angle. Thats bad for flow, and the collector is the most important part. I'd rather have an unequal length noodle header with an awesome collector than one with perfect equal length straight runners and a garbage collector.

If i was going to do it again, I would have not bought a fully welded collector but one that was just tacked or one that was only pre-cut. I'd tack up the whole manifold, then cut the tacks somewhere in the middle of the runners that made it easy to finish weld at the flange. Then cut the tacks on the collector, finish weld around where the runners meet the collector, then weld up the collector. Make sure the runners still all line up them finish weld the runners on the flange and collector sides, then mate them back up.

This is a good collector, but how do you weld that with 4 pipes on the ends?

How do you possibly fit the torch inside and do a nice weld? And it wont look nice on the outside at all.

there MUST be an answer the pros know that I just dont.

You leave enough pipe after the collector so that there's enough room to fit the electrode in there.

I guess...?

I couldn't figure it out, so after making my pretty collectors and welding 2 of the 3 pipes onto the collector, I had to cut the collector in half so I could fit my fat gas lens inside and weld along the inner surface of the 3rd pipe. Suck.
