Did you guys weld it up with the funky flange? i see #4 is notched at the top bolt.

Patrick,
The header you built looks Great!

Yeah I'll be going out on the Friday. Not sure on the Sat just yet. I'll look out for you.

Exactly as Spencer outlined. I didn't realise this. I had hoped we might be able to massage the old headers to work but it was going to be pretty touch and go. Especially trying to retain the bungs that were already welded in there. The time to modify the old ones vs making up new ones wasn't that different and the new ones while not Paul's 'prettiest' work, are actually much more even in terms of length than the old ones which had quite a bit of variance across the range. The CC value of the headers is almost exactly the CC of each cylinder for what that's worth. These headers may not be perfect for chasing tq but it's really tight in there with canted motor and steering column. The X-over needs to be shortened a little bit too.

Yes, we did have to make room for the new larger housing on the turbo. Now that we're out of WTAC for this season I started back down the path of doing the twin scroll EFR swap...but it's a big job and again, Paul thinking of my pockets convinced me to stick with what we have and just get the car on the track again. While this turbo and exhaust size won't be ideal to extract the most out of the motor, I need to stop the bleeding and pay off some debts so we'll stick with what we have for now.

Perfectly put!

Yes, funky flange made up as the #4 is different to the other 3. Because Porsche.

Thanks Max.

In the last two motors we had the steering shaft actually touching the headers and that is with the motor 'shifted' to the left on the mounts to make extra room. With the new headers Paul was careful to allow more room and we've gained about 1/2 an inch. Doesn't sound much but it's not rubbing!

The intake cam wheel also pushes through the hood line so we'll make up something to allow it to work.

Looking good Patrick!

Patrick...
How would you feel about a LHD racecar?
Might free up some plumbing room....

I'd have put a thick washer over that stud and welded it onto the flange

LHD would be better for a few reasons. Steering shaft being one of them but also we could relocate the turbo somewhere down in the passengers footwell area.

That won't be how it looks once it's finished. Just hanging in place for a quick picture.

Thanks Shawn. For a long time now I had thought there would be no way we'd possibly beat you to tuning our 16v motor but perhaps....So where's that at now? I know there were some holdups for paint. Must be ready to go now, yes?

Sorry wrong thread

Holy crap how'd I miss this?

Mine is going to be the street, little brother of yours.
Just got my head back.......plenum time...... Sigh.

Small update. So with the motor having been in the car for some months now and no work going on we will slowly be moving forwards again. Have decided to do the whole EFR twin scroll turbo change. Going with the 9180 t4 ext w/gate model. I also bought one of Rod's spare housings (1.05) as he uses the 1.45. Being that our cars are in different classes and he has paddle shift SQ box vs our stock syncro, I decided to try the 'small' housing to get a little more response out of it. Rod suggested it wasn't a huge difference but it's a starting point for us. Along with that will be the twin X over pipes and gates. Plus a new turbo back exhaust. Ours is 3" and I wanted to go to 3.5" or 4" depending on space.

The water pump has been mounted. Not too many spaces for this but it looks like running low down off the radiator will work nicely.

We're also upgrading to a new ECU / and Dash. Another member bought our old ECU and other parts which has helped in offsetting some of the costs.

We're also working with a local manufacturer of high end intakes and may be employing one of his 'creations'. http://www.customplenums.com/
More of that later with any luck.

As you can imagine, we're very keen to finally get this motor finished and tuned.

Am going to have a few things to sell soon. Not the least being the 2.5 racemotor. This is a high end build with all the 'right' pieces on it and saw over 520whp on the dyno. It can be supplied with a custom intake, 4-1 headers, modified X over, GTX3582 turbo with any of the 3 housings. Full 3" s/s exhaust, billet dry sump pump mount and oil pump.

I also have the head/cam/intake from the 3.1lt 8v motor available. This has all the good stuff on it too. Saw just under 250cfm with big valves/cam. One the 3.1ltr motor we saw over 550whp. Can also be supplied with some of the options from the 2.5lt racemotor.

Probably a few other things I have forgotten. Anyone with genuine inquiries can P.M. me for details and possible pricing.

Awesome work Patrick. Keep it up, that turbo looks like it could swallow a few children!

Glad you went the EFR route. There will be more mucking around with headers ect but it'll pay off. It's a huge turbo though! interested to see where and how it gets mounted.
WP is mounted in a good spot too.
Good luck.

Thanks guys.
Yes, it looks massive doesn't it. We shall see how it responds but Rod and his engineer were confidant that we should opt for the same model turbo as them. Just a matter of getting it in hand so we can start fabbing up the Xovers etc...

thingo

It's a great turbo, but yes it is a big thing to fit in.
