Speedtech Twin Scroll N54 bottom mount kit Released

[Jeff@Speedtech]

Good find. Will you be modifying your manifold to fit Gen5 gates? Or just not offer the Gen5 gate?

I don't think many of the current kits with the Gen5 will likely see any issues, as there should be enough clearance to function properly, but there is a tolerance stack to this, so to be sure, I'll give the few guys (most choose the Tial MVR) that have the Turbosmart Gen5 a heads up, and add a machining op to take off just a bit of material to ensure a worst case tol stack will never touch on anything going out (Tial or Turbosmart) from this day forward.

I ordered a 38mm WG block of kit from Ebay for $30.
Best Smile/$ mod I've done in a while.

Any issues at all since you’ve disconnected the WG tube and blocked off the port? Nothing melting? I’m considering doing this on my kit.

No issues yet. I want to extend the WG dump to exit near the sub frame to lighten any melting worries and for a cleaner sound. I'm waiting for an external dump option from @Jeff@Speedtech before diving in to something custom.

Has anyone had the downpipe or dump tube ceramic coated? I'm would love to wrap it to keep temps down but I'm afraid of the possible stress and corrosion it will cause. I'm ready to install but wondering if I should have my downpipe and dump pipe cerakoted and wait another 2 weeks for the install.

I had the manifold and downpipe ceramic coated and wrapped. I also run a turbo blanket for the hot side as well. Seems to hold up well.

Just a heads up if you order this kit and use an AGP Borg Warner turbine housing it's going to push the downpipe out of alignment of the wastegate dump tube. Not a big deal I just bought This 38mm block off plate and swivel the dump tube out of the way.

Hey guys! Having big trouble with my Speedtech kit. Running S362.

Issue is bank1 02 going crazy when getting boost, and misfires on bank1 at 6000 rpm. Coils, plugs and injectors are all taken care of.
Running brand new OEM 02s, front and rear. Anyone with similiar issues and soulutions? Anybody running OEM 02 sensors with clean readings?

They are brand new. Why would there be differences between the banks? Bank 2 is fine all the way!

This guys is having the same problem even with NTK sensors: https://www.spoolstreet.com/threads/lamda-issues-after-speedtech-install.5989/#post-89636

 

[N54135iAT]

is there already an option for open screamerpipe? Thinking about modifying mine by closing the downpipe and extending the screamerpipe to the floor

on there website all N54 Turbo Kits are sold out.
Have anybody news about that?

 

[N54135iAT]

This happened to me with my CES ST and it was the o2's. I now run with the VTT thermo o2 isolating bungs and haven't had an issue after countless dyno pulls and track days. Running OEM o2's. https://vargasturbo.com/product/vtt-thermo-isolating-o2-bungs/

I deleted my statement above because I just recently got my car dyno tuned and come to realize I have the same issue with bank one. Only under boost my STFT's are unstable and i am having minor lean spike's in bank one. New NTK o2, new index 12's, new NGK 97506 gapped to .020

this is slowly rolling into the throttle showing how it gets worse under boost.

They don't fit the speedtech Mani :/


For everyone who asked me about the connectors...

Hey,

Does anyone else make o2 bungs or do you think the answer to this AFR issue just buying the ADV sensors?

 

[JimboFresh206]

@pysical yeah vtto just sells a copy of the innovative heat sinks.

there are other ways to make an 02 heat sinks (big piece of copper etc.) I dont know of anything thats shorter/shallower that still has the semi closed tip to help with pressure :/

I think you guys should give ADVs a shot?

This is the absolute worst log I have with them and a boost box with clogged secondary cats, and with about 12k on the kit+them

Finally I would also post a few pictures of this nice Kit.
The fitment and the quality is really fantastic, thanks Jeff, also for the fantastic support!

So, pictures say more than words....

I ´m running OEM O2 sensors (more than 25k miles on it) with no issues so far, but still running on spring pressure.
