4k-c Turbo Build!

No welding today :( dad is tired.

I spot-welded the plate for the wastegate to a small pipe (acting as an extension)

Ill get it welded when I can..grr (Suppose not a huge issue, need the right angle fitting for my booster)

 

Anywho list of remaining items before drive test 1:

 

* Remaining welding

* New throttle cable bracket

* New coolant lines

* Battery +ve wire

 

As a side note, what do the people think about this?

I will need to paint my manifold to prevent rust, I bought a can of wrinkle red paint ages ago and did a small test on the cut off 2.5" pipe from my manifold log.

Its only one coat and no primer, but was just a test:

Its either that or black (My rocker cover is already black and my silicone joiner is red)

    Mate give me a break, its a correctly sized turbo for that engine capacity. I can't run an intercooler so I wanted something that will compress the air efficiently; itl do just fine.

The waste-gate is also just about done :)

Just need to get a little 90 degree bend for the outlet of the waste-gate to follow down along side the pipe.

Ok update time again :)

 

Battery wire relocation just about finished, the power wire has been run and connected and so has the Battery isolator switch (Free I might add :D)

The wiring to this has been neatened up a little now, its just an earlier photo :P

Made a larger ground wire with the left over peices, just to make sure :)

IMG_2459.jpg

 

Iv ordered my Boost bleeder Tee and that should be here tomorrow (Fitment tomorrow :))

For tuning purposes ill keep it at the stock gate pressure (3.6psi)

Once I'm happy with fuel and timing, I shall bump it up to say 8psi?

Thoughts peoples??

I searched the forums for results, but most of it was all assumptions based on what they had been told.

I could understand 10psi being a nice upper limmit, but I came accross one guy that was running 15psi on a stock motor for over a year now.. hmm..

 

I think I failed to mention previously that my oil return was brazed in, and thats sitting there rather nicely now :)

My external gate is awaiting a 90degree downpipe to point its outlet away from the firewall.

 

IMG_2456.jpg

 

 

I had some left over exhaust wrap from a mates car that I helped with, and well to keep the oil lines behind the engine happy I wrapped the downpipe :)

IMG_2439.jpg

I also wrapped the two outer exhaust runners to protect the power wire and the coolant lines at each end.

IMG_2437.jpg

 

Iv re routed it and made a bracket that goes to the throttle lever so I can mount the cable horizontally along the manifold :)

I don't think I have a photo though..

You can JUST see it in this one, but you get the jist.

Need to secure my fusebox some how... I hate making brackets :P :(

 

Tomorrow I should have my manifold and coolant lines back from welding.

Welded on not it will allow me to make my throttle cable bracket.

i'm starting with 12-14 on my supercharged 4k but thats E85 and i plan to go higher :) i have heaps of pulley's i used dry sump tooth drive pulleys so we have heaps of spares for different boost :)

Testing purposes* Lol

Ill wind her up once I'm happy the hoses and the throttle cable arrangment.

That and I need to buy an oxy sensor gauge, have the sensor already.

8psi to begin with, my diff is about to shit itself and I need to replace a bearing before I put too much strain on her :)

I think ill settle around 12-14, plenty of time to work that out :)

 

If all goes to plan, I should be able to drive it this weekend or earlier :)

Update 1.5

 

Cut and tacked on the waste-gates down-pipe, will be welded this weekend hopefully :)

IMG_2464.jpg

 

New end caps are on :)

IMG_2467.jpg

Still need to weld in the piece for the brake booster, but tomorrow hopefully.

 

IMG_2472.jpg

 

Tomorrow:

Boost Tee arives

Coolant lines SHOULD be welded

Manifold will be ready to paint (booster peice welded in place)

Throttle cable bracket should be done.

 

Providing the manifold booster piece and the coolant lines are done, I'm ready to start her up again :)

 

ET for first drive assuming welding gets completed tomorrow: 2-3 days (Worst case Saturday)

Could do, have somewhat access to a dyno at tafe.

For now at least, ill adjust until its running visibly rich (Or until the exhaust pops and crackles ;) )

Once I wire up my O2 sensor ill do further adjustments from there.

What more can they do on the dyno than I can do with a AFR gauge in cabin?

SU's are pretty simple things, you can move the needle around or just adjust the base mixture screw.
