Bellow was from http://www.atpturbo.com/ The bellow in nothing special and can probably be had from a number of sources. I have typically used Slip Joint Bellows, but those are not designed for axial movement so I was concerned for this application. However, if located directly below the engine rotation point it would probably be fine as i suspect it would see linear movement. Another advantage is the slip joint bellow is smooth on the inside, which is better optimized for flow. Downside is $200 for 3.00".

Contact Advanced Thermal Products for pricing, but shields are not cheap. With that said, I don't think you will find anything more effective.

 

Patiently waiting for MOAR updates/results!

I took a week off from the project due to travel, but I plan to proceed quickly upon my return. I spent ~3.5hrs porting the exhaust manifold to remove flashing and smooth the runners. I also need to port match the turbine inlet as there is a slight alignment issue with the manifold.

I am likely going to ditch the Tial 38mm to 44mm adapter that is shown in the previous pics. I will have the wastegate hole bored in a mill to 1.75" and then weld a piece of 321ss pipe to make a true 44mm setup. I suspect I will have the car finished in ~3 weeks. I will post pics when I return.

 

nice project! Can I ask you where and how much you bought that Revhard manifold for?

I've been thinking of doing something similar...but using the stock manifold with t3 adapter and welding a external wastegate flange to the stock manifold. Might be more trouble than it's worth though.

 

I don't remember where it was purchased other than a shop in CA. As I searched my old post I paid $285 shipped. I will search around to see if I can find another source, but you might try searching RevHard or Blox manifold. Also, there are two manifolds that fit the head, but you need the one specific for the EVO as it places the turbo in the correct position. I'll see what I can come up with.

 

I found a company that has one remaining RevHard manifold for an EVO at a cost of $220. PM for information, but I will post on Friday for anyone who is interested.

One is remaining at the following company.

UPDATE:

My attempts to remove the stock O2 resulted in a damaged sensor. I soaked in PB for several days and tried a wrench, but ultimately I had to use the impact socket and it jacked the threads. Not wanting to spend $350 on an OEM replacement I opted for the Denso plug and play for $63. As you can see it is a direct fit to OEM and is also Denso like OEM.



Because I was using the Tial 38mm to 44mm adapter I was thinking about welding a 1.75" pipe to the top of the manifold to make it a true 44mm. However, after measuring everything the adapter would allow me achieve this goal. Pictured below is the valve seat for the Tial 44mm, which measure ~1.56" as opposed to the top of the manifold that measure ~1.54". You can see the adapter has an ID of ~1.40" so it only required some porting to make it match the Tial valve seat.




After about 30 minutes of porting I was able to make it ~1.50" and the adapter now matches the manifold.



This is a picture with the Tial valve seat sitting on the adapter before I did the final porting/smoothing.


Lastly, I port matched the turbine housing to the manifold.


Next task is to have the manifold, adapter, and dump tube sandblasted so I can apply the high temperature coating.

 

Hi 240Z,
mind to share the Denso O2 sensor code?
Planning to change my old O2 sensor.

UPDATE:

I had the manifold, wastegate adapter and dump tube sandblasted. I then coated with the 2000deg thermal paint. I have installed the wastegate adapter and wire tied the bolts so they wouldn't loosen.



I then installed the turbine housing to the manifold. I ordered some metric studs and top lock nuts so they wouldn't back out.


I am starting to assemble the setup so I should have some updated pics over the next couple of days.

 

UPDATE:

Wrapped the lower IC pipe with some adhesive insulating reflective tape as it sits fairly close to the coated downpipe.


I also got the manifold installed with turbo, wastegate, and downpipe. I won't say it was hard, but it is always a learning experience trying to reach all the bolts and assemble in the proper order. I will try to get some better pics tomorrow and I should finish the assembly except for a few minor hoses that must be fabricated.

 

very nice.. looks good.

 

UPDATE:

I had a fun weekend trying to install the dang water line with the turbo installed. Unless you are using banjo style fittings this is not something I would recommend. I ended up modify two wrenches and a socket (11/16") to allow me to access and tighten the fittings. Some of the trouble was caused by a reduction in space due to the turbine heat shield.


I finished fabricating the turbo inlet tube, which was a modified HKS intake as well as welded some 1/8" NPT bungs to the intercooler pipe for boost references for the wastegate and wastegate controller. I will take them for powdercoating on Monday.



The remaining pics are just some various angles.




I need to order some remaining hoses and hose ends as well as fabricate my enclosed catch can. Other than this the car is pretty close to completion.

 

Great DIY work. I'm curious to see how the coatings hold up. I've heard the adhesive heat reflecting tape doesn't stick for very long when close to a heat source. DEI makes a hook and loop fastener (velcro), non adhesive, heat reflective material you could try as an alternative if the tape begins to peel. I've been thinking of using it for IC piping and the intake pipe too...I like that it is very non-permanent and can slip on and off as needed. Good luck and great work...I'm very interested to see GTX 30r results on our cars.

I had the same heat reflective tape on the same part of the oil pan. After about a year, when changing my driveline fluids, the whole sheet of tape was gone. It fell off sometime in that first year. I never scuffed the pan before applying, but I did clean the crap out of it with brake cleaner. Kinda disappointed with how that turned out.

Sweet heatshield for the manifold, though. I'm all about reducing heat anywhere I can.
