TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

The standard instructions routes the hoses to a stupid place IMO. The way the hoses rest on the brake master cylinder reservoir is a great way to eat away the plastic of the reservoir which will eventually causes a rupture due to hard plastic on plastic chafing.

 

When is the last time that you changed your fuel filter and fuel pump?

Grab a recliner, and set aside a week to catch up.

 

I would ditch this sooner than later for the sake of your motor's health. Welcome to the boosted club man!

 

I gave the man the link to the HPT thread along with the names of the people to reach out to. He’s more of a pop the hood in a Malibu mall parking lot kinda guy than a head to Mexico and see what the truck can do guy. Ain’t it right @kasnerd Gonna get you some love just like in the jd thread here haha

 

I have a catch can I need to install. I was going to order 10’ of hose and a couple T’s to run from both valve covers to the catch can, and then to each inlet port, or cap one and run to the other. But I’ve only seen people pulling from the left valve cover. Is there a reason I haven’t seen anyone connecting to the right valve cover?

 

Speaking for myself (and quite a few others), I pull from the PCV valve, not the valve cover. Theoretically, the valve vents the entire crankcase, vs. the one side.

Besides, it was much easier to tap a line between the PCV and intake then add a breather valve to each valve cover.

I seem to remember reading a discussion earlier in this thread about venting each side. You might try searching - not sure what to use as a search term.

 

on my race truck I run both sides to a catch can and vent to atmosphere. on the tacoma I will also run both sides to a catch can but have not yet decided if I will vent to atmosphere or return.

 

@3pooches

See below.

 

On the 6.2 (gdi engine) its a complex catch can (cc) set up. (By UPR)

pcv -> cc
Cc -> air intake port with y to oil cap clean side separator (replaces oil cap)
Cap passenger side valve port that went to intake port.
Driver side valve cover -> cc.

Took a minute to wrap my brain around what they were doing but basically it's designed this way for vacuum and wot running.

 

This is what I was thinking of doing. The ~5/8 hose, that connects to the air box right before the throttle body, is a pcv vent hose correct? I saw it labeled as a “clean air inlet” but not sure how it doesn’t suck in junk from the right valve cover. What @JasonLee posted is everything I’ve seen, they only attach the can to the left valve cover. Does the system pull from one side and push out the other?

 

Could be due to packaging, budget, or just don't want to do it. While the driver side has a one way valve the passenger side is effectively an unmetered port. Just open, no one way valve.

 

That is correct. The passenger side valve cover hose which goes to the intake is the fresh air inlet. The driver side has the PCV valve in the back. One way in, one way out basically.

 

Thank you for clarifying. I’ll be running my catch can the same way as you.

 

I changed the pump to a deatchworx 320lph e85 (URD kit) with new sock and the external/remote napa gold inline filter about 3 years ago, one of the first real mods I did.

I can't imagine the giant filter is stopped up already I generally only get gas at Wawa that's ethanol free. (89 Oct.) If that's not an option I stick to 'Top Teir' stations and get their premium.

Where does the fuel rail pressure regulator hookup on a supercharged motor?

 

Depending on the mileage, and a few other factors, it could be. Wouldn't hurt to change the filter, since it is so cheap.

You could hook it up from a port that sees boost and vacuum, or do like Toyota typically does, and route it from the intake tube, pre TB.

I prefer a vac/boost source.

 

For ~$10 you can rule out the 3 year old filter though.

 

Got it all back together! Installed urd low temp thermostat, cam gears, ruthenium spark plugs, hps hoses, zzp s/c coupler. Have the fuel pump mod ready to do next, and an afe stage 2 intake waiting to come in

@Torspd is correct with change the fuel filter. im about to. under 20$ and an hour that it peace of mind done cheap. then we may have data to help others out.
