Not really any lag just peak power comes on a bit later with a bigger hit.

you will notice more tq at all rpm ranges than stockies. You will be happy.

Nice! I am looking forward to hearing how it goes. I have the following on order coming from Rob next week or so.

*RB Next Gen Plus’ (TD04L-9 Blade Turbine with 17T Billet Compressor/Ported Compressor Housings)
*RB USA Made Billet High Heat Anti-wear match wastegate upgrade
*RB High Flow Silicone OEM Style Inlets
*RB High Flow Silicone Angled Outlets (including Heat shield and Wastegate solenoid bracket)
*RB Custom 2.5” to 2.5” Intercooler adapter
*RB High Flow Oil Drains
*RB Basic Install Gasket Kit
*RB PCV Valve
*RB PCV Screw-On Cap
*OEM Vent Hose

I have a wastegate stuck open on one of my oem turbos after 40K tuned miles, so its time for an upgrade

My standard RB's lag a good amount more than stock. Stock feels solid from like 1500 but my RB's with inlets really dont kick in until 2500-3000 rpms

Installed my new RB Turbo Next Gens & turns out the JB4 stopped sending the signal to close the waste gates. That's what prompted me to replace my stock ones. A costly rookie move replacing the turbos when I should of removed the JB4. It gets better after replacing the turbos and still not making boost my mechanic had me replace a few vacuum hoses & two boost silinoids. After pulling the JB4 my waste gates closed & back in business. Now I have to go get a custom dyno tune. Man I already miss those cool features the JB4 offered.

Will you be running inlets? If not, may as well do those while you are in there
