Post your interest in having Chris do another run of the TU Cast Header

[cornflakesglht]

any updates on this ? i would be down for 2 headers !

thanks

I will just jump in and say that I (according to Chris) ordered the last available header he had. It's an awesome piece! The only thing I would like to add, is be very careful if you do get one and have the special heat coating applied. I had to do some pretty severe grinding with a carbide bit (through the coating as well as deep into the cast iron) because it was absolutely impossible to get the nuts in. Even with doing this, I had to "angle" the header down over the studs and start the nuts a few threads at a time. I will never be able to re-torque or remove the header with it in the car. I understand that this is a custom piece, and moves the turbo to a non-standard location.

That being said, I am still glad I ordered it. I will see if I have any pictures of the modifications I had to do, and post them this evening (providing my worthless cable company shows up and restores our service).

I would buy one!

What about using the small 8mm hex I think, with built in washer nuts that where used on a stock setup?

It would be nice to have a wastegate boss right before the turbo cast in. After all the cylinder primaries.

Funny, my friend Steve (glhs613) bought one a couple months ago and was told it was the "last available one" too

The one I had and the one my friend has both have external wastegate bosses cast in them. They are in the middle of the manifold though. It would be extremely hard I think to have one at the turbo inlet.

I think it could be accomplished. I did so on a weld L manifold from TU.

I'm sure it can be done, but it would make things much harder to work on I'm sure. I got aggravated enough as it was, I wouldn't want anything else in the way lol.

I would be interested in buying one of these. But honestly I would like to see the other TU Group Buy on Maserati valve cover gaskets come to fruition before getting involved in another.

Well, you can see by these photos how insanely tight the fit was. It does look great on the motor though.

[wheming]

Which turbo do you have there??

[glhs875]

Yea, that's tight!!! Looks good though!!

[MoparStephen]

It's a T3/T4 hyrbid, .50 A/R, and a 3 inch swingvalve put together by Chris at TU. This thing moves a TON of air - I definitely need to upgrade the stock intercooler.

So when you installed the manifold, did you have to start the nuts with the manifold held out from the head a bit and thread them on incrementally to compensate for the studs being so close to the casting? Did that work allright or did you have to resort to shortening the studs or cutting some of the material off of the manifold to provide clearance? Thanks for posting pics. That is the kind of thing I would like to know about before purchase.

[wheming]

Chris has stated in his header installation instructions to work those nuts down incrementally. It is just the lower bolts that are in that sort of positioning. And that was designed that way to maximize clearance to the firewall.

I'll be installing what I thought was the last new cast TU header very soon....

[iTurbo]

Sounds good. I have a Cosworth turbine housing from another vendor that I'm going to have to do essentially the same thing on to get it installed. No biggie really, just nice to know ahead of time.

I did not have to modify the studs at all, but I did have to remove material from the manifold. Without the special heat coating, this may have not been necessary. The coating is very thick and textured. I did as you said - incrementally lowered the manifold down as I was installing the nuts.

With the motor in the car, firewall clearance is excellent, and I had no trouble at all installing the full 3" exhaust, with the factory heat shielding still in place. I still wrapped the downpipe in several areas with the header-wrap, and put heat shield wrap designed for spark plug wires over my shifter cables. I plan on making many long trips with the car.

I have a ton more pics. I had to customize the turbo support bracket with this setup also. If you have any questions, or want to see how I fit all the oil & coolant lines, wastegate, etc. just let me know. I will start a new thread so I don't completely hijack this one.

[iTurbo]

Awesome, thanks for the feedback. It really doesn't sound too difficult at all really. I will be watching this thread for sure because I've always liked the fact that TU went the distance and had something like this cast.

Did you have any issues with regards to the vacuum booster clearance and intake piping? Seems like I have read about some people having problems with that before, but I also have my own ideas on how to overcome that, if it does become an obstacle.

[MoparStephen]

No - I didn't have any issues with the brake booster. I did have to customize all the piping, I think have some shots posted here, along with the part #s for the adapters. I am lucky, in that Summit Racing's main headquarters is a 5 minute drive from my house. It's one of the few perks of Akron



Here's the link to the post about the piping I used : http://www.turbo-mopar.com/forums/sh...l=1#post994285

Yes please start a new thread on the T.U. cast header if you have time. I recently bought a bare used one.

Thanks

As posted by others those nuts are hard to get to, but very doable, and the thing is ten times beefier than stock so no worries about cracking it. It put my T3/T4 .50 trim too close to my heater hose connections (l body) BUT maybe my bobble strut isnt right...honestly I didnt even care to try and fix it, it is only a summer driver( Im sure it can be fixed), dont need heat. I even had to go back to my S60 and I it worked for that as well (chrysler flanged)...I just had to work on the drain tube a tad....all in all good product.

We had set aside a few TU Cast headers for our own project cars. When plans change with the vehicles we may decide to sell off the header designated for it. We have also acted as a mediary for other customers who have moved on to different vehicles and have contacted us to look for a buyer. In the case of Steve (glhs613), he purchased an experimental manifold which was converted to a Ford style turbine flange, not a standard Chrysler flange. The OP purchased his header years ago and was fortunate to obtain one of the last cast versions that was not already spoken for.

The close tolerances of the studs to manifold was not only done for the firewall clearance. If you look back at the threads where we were posting flow bench results we saw a drop when the manifold was extended out further to clear the studs. We refuse to build a product sacrificing performance in order to simplify install. If done properly the install should be a one time thing where as performance is all the time.

Hope that explains things better,

Thanks!
