Sam's build thread

Eddy when you fitted your turbo bolts did you do them up f#####n tight or to spec before you welded the heads?

Hoping if anyone who has a genuine borg warner K04-001 can help. I need both the VW 06A.... number and the full borg warner K04...... number off the turbo placard so that I can get a quote for a newbie off GCG. I was quoted $1550 for a complete new K03s and $650 for its core. That core price was looking unreal until I found the exhaust housing cracks. But now if a complete K04-001 comes in at less than that I may go the K04 route and just sell sell sell everything that's not bolted down in the garage for the hardware/tune to run it. Anyone got a stg 3 APR ecu out there that they want to swap with a stage 2??!!

First of all my Ko4 does have that turbo bracket, but added extra webbing for strength & then added another one with pressure pushing up when tightened up.
I done the turbo bolts extra f***** tight.

gotcha. ha ha re the bolt torque - I thought so. I've made up my mind then. I'll re linish everything, use 12.9's with a short shoulder to fill out the oversized manifold holes, use the big O.D nordlocks that arrived yesterday and do them up f###### tight like you say.

Now to just sort a turbo to put in there!!

Sorry I can't help ya with the Borg Warner Ko4 No's Sam, with it bolted up I can't see what it is.

[sambb]

no worries. I can barely make out the numbers with it off the car!

Hoyhoy.

Well, well Borg Warner are now made in China.
I don't know if the No's on there will help Sam.

nice Eddy. Good detective work. thanks for that. Genuine Borg warner made in China.... really! hopefully that's a counterfeit badge on the turbo and they are at least made in the EU. When I call GCG i'll definitely be asking about the made in China thing.
I sent the pics of the cracks to a few people and was surprised that they thought the cracks could be easily/reliably welded. Maybe the K03s with a new centre is still in the game. To be honest for the hillclimbs I do I think the modded K03s is spot on. It just has instant throttle response and is basically lagless. It feels like an NA which I love so I'm more than happy to stay with it even though its being pushed really hard.
