Rinus gt4082 build

[Rinus]

He good people

 

Like to share some pictures of my setup...

 

Started with;

 

Cast-manifold (turbonetics)

Garrett Gt4082jb

Mines wastegate 35mm

Aem intake

Xs-downpipe

 

 

At first drill out the wastegate of the manifold, it was a bit small, 32mm;

 

Now it matches the mines wastegate 35mm;

 

Modify the downpipe,

first cutting 3cm off the beginning of the downpipe,

where pipe connects to turbine;

 

After that cut out 5cm in the middle of the pipe;

 

And 10cm at the end of the pipe;

 

Ready to weld;

 

Testfitting;

[Rinus]

And getting the screamer pipe back in exhaust;

 

My first time wrapping ever, so be gentle...

Will get the T-rips offff:Pling:

 

Oil drain, with custom made flanges;

 

Blockoff waterfeed, pipe has been pearled (no its not a new one );

 

 

Has anyone an idea what the big sensor is for?

Does it acctivate the little airco fan when its getting too hot?

Cause I thougt myself the sensor at the bottom of the radiator does that...

The little one is for the stock temp gauge I think?

 

2 spal fans, thats why I like to know about the sensors:);

I bought one sensor 87-82 degrees, dont know best place to fit...

 

Right know I'm waiting for the vband flange from garrett,

for the outlet of the compressor (to fmic piping)

This is smaller than 3inch and bigger than 2,5inch ,

7,39cm cross-cut...

Cause of the vulcano problems I'm waiting 6weeks already

 

 

If you guys have any comments, good or bad, will appreciate that...

 

Cheers Rinus

on the water pipe, the small sensor is for engine temp guage, the other is for ECU I belive.

Yes, that's how they are. Very nice set up, cast manifold, flexi sections in both down and wastegate exit pipes, and neat welding It should be a reliable set up. My only concerns would be the small amount of material around the hole for the wastegate, if anything is going to warp and blow it will probably be there, but there are options to retrieve it if it does. The other is are you sure that turno oil drain hose is up to the temperatures involved? It also looks a bit small on the ID of the fittings, but a ball bearing turbo doesn't flow that much oil around the cartridge, so it will probably be adequate. Please posy more info as it progresses

Do tell Chris, as I have a similar set up...

[Chris Wilson]

You could have a square section groove machined in the manifold or wastegate flange to take a ring, of the type similar to where the stock turbos mount onto the stock manifold. They allow some movement and still maintain a seal. I think Wez had the adaptor welded on, but maybe that was due to cracking?!

[Rinus]

Ok,

I hope it will hold around the wastegate,

I think its no option to weld a stainless steel wastegate flange,

to the cast-manifold?

But its a good idea for a ring groove drilled if it blows...

 

@ chris its journal-bearing, so a bit more oil will get trough the oil drain...

The material of the oildrain is an hydraulic-hose 300bar,

outside is sort of plastic, but inside its steel...

So if it melts I will first smell it...

Thinking of some sort of heatwrap/tape around it,

I will measure the smallest hole of the oil drain,

I think it should be big enough or is there a minimum size for an oil drain, for journal-turbos?

[Chris Wilson]

If you are in doubt I would refabricate using mainly alloy or steel tube with connectors made of silicone with a flouro/silicone liner. The liner isn't vital, but stops long term osmosis of the oil through the tube walls. I use these people as they are local, but their delivery can be unreliable..... http://www.viperperformance.co.uk/plainpage.php?pgId=28

 

I would aim for 12 or 13 mm bore pipe and push on fittings. Swaged and crimped bolted fittings have too small an internal diameter to use with sensible hose OD sizes for this sort of application. Look at the size of the drains on a stock 2JZ-GTE or RB26DETT engine to see what the manufacturers use, they are quite big ID hoses.

 

Not criticising, it's just that a restricted or unreilable turbo oil drain can cause serious problems.

[Rinus]

I appreciate that you give your opinion,

than afterwards comment when I blew up the car...

I will compare my oil drain with de stock one and then make a decision...

I'm not affraid of melting,

have seen a frien of mine with tubular manifold,

with on the compr-outlet a 90degrees plastic pipe only 1/2 inch from the manifold and no burning or melting [sHOCK][/sHOCK]

 

The watertemp.sensor for the ecu (the bigger one in the elbow),

what doe the ecu with these data?

[Chris Wilson]

It makes changes to injector pulse width and ignition timing based on coolant temperature. It's a very important sensor.

[Wez]

I think Wez had the adaptor welded on, but maybe that was due to cracking?!

 

I had issues at Marham where it blew the wastegate gasket out, I replaced it but it happened again so I removed the gasket, cleaned the faces, bolted it down and had it welded. Hasn't given me an issue since.

 

My cast manifold was modified by Induction Motorsport, they build up material around the wastegate port and then bore it out.

lekker bezig rinus !!!

 

Lots of respect for this project! Next winter we will do mine
