Yep. That is it. It is like ~180 after shipping. Seems like a good unit, well built but hard to install if you have studs like me. I actually had to grind on the unit some.

I will build something to make it fit, you are right it would be better with a different header. This would be another thing I could potential make for people (when time becomes abundant). It will be a pie cut stainless short radius elbow semi fabricated from scratch.

It is just aimed down because it was originally used as a recycle BOV when it ran on the stock ECU. Obviously it is on Megasquirt now.

Thanks

I think you may have passed the point of no return here but if you can't find a 90 to fit the down pipe you could try this.

Love the build.
Do you have the dimensions on that grill opening?
It is by far the best cutout one I have seen.

I've always wanted to make a manifold but feel like this is easier.

I don't have any on hand but next weekend I can try measuring it for you. I just kinda went with something. I like it as well, i tried matching what I thought the cosworth was.

No real updates with weekend, doing other things, spend a few minutes on this. Here is the down pipe. I started it and it wasn't really that bad just need to add a bit more heat wrap/shielding to keep the brake line from baking.

Looking good! You can also just move the brake line - it's just as easy :)

I had some time. So I copied your grill.

Where did you get the studs holding your V-Band adapter to the turbo?

I could use some of them myself.

Thanks!

You can get them @ sears hardware, mcmastercarr, etc. Not too uncommon.

I'm not looking for the mild steel ones, I want the hardened steel ones.

Again, both of those places should have that.

I assume the reasoning for the new turbo outlet / downpipe set and IC set up is for earlier boost ?
Is the existing the exhaust under the a car 3" to the back?
I'm really interested in your "seat of the pants" review on this for hopefully good spool reduction.

I am too. Should be interesting. Here is the downpipe awaiting heat wrap. It was pretty easy.

MercMike - Grill looks good. Maybe we can start a trend.

Few images of the changes over the last few weeks. It has been cold and the motivation to go to a unheated garage is low.

Some paint, fans and mounting of items.

Turbo feed

Baffles on the inside to force air through the radiator and intercooler.

Few more additions to the car. Nothing major.

Lower radiator tube made form some tubing I ordered. It runs under the crank pulley nice and tight.

Image

Mocked up some of the exterior stuff it is all in the details now.

Image

Order most of the remaining parts this weekend. So I should be able to get it running in a week or two. Just before the first season autox.
