need specific help choosing a turbo manifold on RB26/30

[dorifticon]

Hi all

I'm currently in the process of attempting to fit a garrett GTX4202R split-flange T4 turbine to my R32, RB26/30dett, and having some issues with my MTX manifold.

It's a massive turbo, I know. With the current manifold, I could probably get clearance between the block and the strut tower with some modification/panel beating, but the problem is the clearance for the compressor housing - it's sitting an inch or so too high (probably would have been *just* ok if it was an RB26, but the extra 38mm deck height has screwed me.

I've seen on the internet some brands that seem to position the turbo a bit more forward, and angled out from the motor slightly. I think I would need it to also sit it angled slightly downwards so the compressor housing won't foul the bonnet.

My other requirements/preferences would be:

-split flange T4
-twin 38mm vband wastegates
-steampipe

Anyone got any suggestions for something off the shelf that will fit?

6boost do 26/30 specific ones that sit lower. They also have different versions depending on the size of the turbo which determines how far forward the flange is placed.

Spoke to Kyle at 6 boost, they do one that sits the turbo lower but it requires modification of the A/C line.

Does anyone know what's involved in that, or alternatively if there's some other kit that avoids the need to mess with the AC line?

OK, new question: Does anyone have/has seen any neat solutions for:

1) relocating the power steering reservoir

2) moving the A/C line out of the way?

It's needed to accommodate the merge collector on the manifolds that sit the turbo lower in the engine bay.

You can just bend the a/c line out of the way and the p/s res mounts fine where the charcoal canister used to sit

nice install - is that an off-the-shelf component or a custom build?

Custom.

6 boost manifold, 8374, everything to suit. Grim Performance in Hornsby, Sydney did the fab work.

twin 4-ports is pretty serious!

what springs are you running in the gates?

0.9 bar springs, 38 mm MVS gates, 8374/1.05.

are you actually monitoring exhaust pressure on each twin scroll bank or just wanted the gates to move a bit quicker?
