Trev's Custom Fabrication

[Trev]

Hey guys, While I was away from the site I went through a lot of changes (including employment), I left road & track (toyota) to go to Signature Performance (nissan) and have been there for 6 months, My role there was to do mechanical repairs but took on the role of fabrication (exhausts, Boost pipes, Manifolds, Body conversions & cages), I am still learning to tig alloy but stainless and steam pipe/steal I am fairly good with so at the moment when I make alloy boost pipes I get the boss to tig them, I have just completed my 1st steam pipe turbo manifold which is going on a RB25, I will leave you with some pics and update when I do something new.

Thats some hot lookin work Trev :lolcry:

 

Noiiiiice !

I wish you were in SA. Then I could pester you to weld my intercooler piping (when I can afford the rb20 lol!)

nice work, welcome back.

I'm currently in the middle of an extensive body conversion, I can't give too much info or post pics as the customer is a member on here, Will post info with his permission.

The fabrication looks good mate, can you ask your boss how much to knock up an itb manifold for my blacktop throttles to suit 2azfe?

 

Oh and glad your back.

Thanks Matt, It shouldn't be too much as its just a plate and 4 flanges joined with tube, Any material inparticular?

Don't care as long as the ports are nicely finished. I guess alloy would match everything else, and light weight is a particular goal for this build. Its got intake ports like a bigport, flat sided ovals. So the transition needs to be nice. The shorter the better really, as long as I can get bolts in there. The mounting plate, and throttle face can be parallel.

Too easy mate.

It has been a while since I updated this, I finished the above turbo manifold and other fabrication and put it on the 33 (will take a pic tomorrow if I remember) so it is now all sweet and running but today I started on another manifold so I thought I would get some step to step pics to show you how I make one.

 

Step 1: Cut 6 bits of tube and cut them at approx 45 degrees (6cyl only) and die grind the sides, This will make the collector.

 

Step 2: Start by welding the collector tubes together in a set of 3 (2 sides of 3).

 

Step 3: There will now be 2 sides of the collector tac welded.

 

Step 4: Linish the bottom of the collector halves so they are flat.

 

Step 5: Weld the 2 halves fully and then weld them together.

 

Step 6: Put the head plate on the engine and position the turbo where it is going to go with the turbo plate and weld a brace on.

 

Step 7: Cut the collector to length and flange width.

 

Step 8: Tac the collector to the turbo flange.

 

That is as far as I got today but I will continue the steps until it is complete.

Did more today and now for the fun jig saw puzzle like part...

 

Step 9: Get various steam pipe bends (tight and wide) as well as some more tube.

 

Step 10: Start by making an outer runner 1st (tac weld only).

 

I started with number 6.

 

Then number 5.

 

Then number 4.

 

Now onto number 1.

 

Then 2.

 

Finally number 3.

 

Step 11: Test fitted the manifold so the external gate pipe can be sorted (looks hawt :lolcry:).

 

Also put the turbo on for photo purposes.

 

Step 12: Tac weld all joins (apart from the collector and head plate) so they don't move or come apart.

 

Step 13: Remove the runners so they can be fully welded:

 

I think I will be finishing it tomorrow pending other work.

That's f**kin awesome, I love your work.
