Dear God I wouldn't want to try this with subframe in. Some parts are already frustrating enough. Stuff gets tight. Angles get weird. Tools don't fit, even though you've got the right sizes. IIRC, I spent about $1500 in tool refresh prior to my single install.
I didn’t think it was too bad. The bolts on the back of the motor for the transmission are far worse imo.

I installed the kit without completely dropping the subframe. I lowered it as much as I could then stuck a 2x4 between the rear part of the subframe and chassis and it created a gap big enough where I was able to install the manifold while attached to the turbo all in one swoop. This kit simplifies everything compared to stock.

They all use a 38mm discharge, I think that's why that's a bit confusing to some :)

@WOT808 did you use a screamer pipe too?
I'm using the recirc pipe that came with my SpeedTech kit. I loosened the WG connection and swiveled the pipe away from the DP.
I have yet to try, but, space may be too tight to rig an extension to the SpeedTech pipe. I may need to make a new dump tube that extends past the sub frame from scratch.

Installing my speedtech kit with a Garrett GTX3076r Gen 2, Installation is going super smooth. Removed Subframe to get enough space to work, since I’m doing on jack stands
Nice... just got my kit last week... my mechanic is doing the teardown and install. Gonna try to document some of the processes. Will be running 6266 on built bottom end (pistons, rods, cams, closed deck). Should be fun.

That’s awesome brother, sounds like a great build. I’m aiming between 520-550 whp, since my engine is stock, I’m not trying to go over 550whp

I’m running a 12psi spring on a base tune which is only meant to run on wastegate pressure, but I’m getting 16psi on my logs, is that normal or not? Should i be worried?

My kit is being built, S366
Shooting for whatever the hell I need to win.

I'm really anxious. I haven't seen any installed pics of the 366 and from all I read they are large physically. I just really hope it fits well.
