TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Your updates are the ones I am currently (and many others i'm sure) interested in the most!

 

I’ll be finding a dyno once my motor is all done. Very curious. I’m praying for over 400 but the number isn’t a real big deal for me. I love my truck and will be happy with what it makes. If I want it faster I will have to save for a t56 swap. Will be night and day difference. I didn’t go stroker but with internals in lower compression and kelford cams and some port and polishing work. I feel like it will get the job done.

 

Do you have to worry about state emissions testing? Otherwise, did you consider a larger blower like the Rotrex/centrifugal charger for the future? Obviously it's fun to build and see where you get with your current set up but I think you'd get into the 400s much easier with a cheat code lol. We used to compensate every little bit, up the compression slightly with high CR pistons/thinner headgasket, ARP studs everywhere, run tighter ring clearances, lighter weight oil on race days (depending on duration). I really appreciate all you're going through. Can't wait to see after the break-in.

Seems like we have to take advantage of it all on our 1GRs

 

The t56 is by far the worst transmission ive ever shifted. Granted i dont have a manual tacoma so take that for what its worth. Driven bmw/vw/honda/nissan

 

My cousins 6 speed f350 diesel shifted better then the taco

 

The T56 is pretty garbage I agree and so is the Tacos as well as far as shift quality goes. I believe their notchy shifting has to do with an imprecise shifter though, as I have noticed many folks with both transmissions (GTO and Taco) remedied their clunky and just overall sloppily feeling assemblies with the installation of a Hurst short shifter and a TRD short shifter for each of the trannys respectively which solved all of the horrid feelings entirely.

 

I have a mgw on it. Itll occassionally get locked out of first gear at stops if you happened to not put in while rolling. 2/3rd have slow synchros (might just need new ones)

 

Yeah I remember reading a lot about bad synchros as well. Auto or manual, no one is exempt from issues right? Lol.

The MGWs were good short throw shifters as well. I guess these are just the pains of high horsepower.

 

Emissions in NY are simple enough to pass. no sniffer or visual inspection. Just a safety check and no check engine light or pending codes. If or when the larger blower becomes available for us - I can see myself getting it or maybe someday I'll join to dark side with @Torspd and get a whistlin wirly boy

 

You guys have any good Boxing Day hauls to brag about??

 

Most counties in CA recently changed to this. Just plugged up to see the monitor systems working. But visual is a pain. Still need carb legal stickers on everything. And luckily they didn't comment on the DT Ypipe but the resonators almost pass for cats. I want to follow the whistly whirly swirly path!

 

Got a new twin scroll turbine inlet flange. Each inlet is 2" tubing. Next month I have plans to mock up and fab that one in. Reducers to 2.25" and some bends, and shouldn't take too long. Currently a tangential inlet, into a twin scroll turbine housing. Not making use of the efficiency that it could. Should make it much more responsive, even for the size of the turbo and the inlet A/R. Means boost quicker.

 

I pulled out the restricter jet thingy before a long road trip from Denver to Dallas this past week. OMG. Made a huge difference with getting rid of that lag! I was passing people like a pro! lol. Should have done this three years ago.

 

As far as the actual y-pipe diameter though, is there any benefit to having it be 3" or is it best to keep it 2.5", then to a 3" flange/v band for the remainder of the 3" "cat back" portion? Doing a brief search, it seems as if most headers are 2.5 at the collector so im thinking the 2.5" y pipe to 3" exhaust may be best?

 

Mine is 3”collector to a 3” URD Mark lll exhaust. Prior to the jfr I had a URD y-pipe. All I can say is it flows/runs much better now. It also sounds dramatically better....

 

Nice! I am currently running your old setup, URD Y into a TRD cat back. I'm also switching to the JFR Y and a 3" URD. Good to know it all sounds awesome, I cant wait to get rid of the rasp and choke of my current setup.

 

Finally able to rev it up a little as the tune is getting closer to right and I feel more comfortable pushing it some (big thanks to @JustDSM ). Maxed out my maf sensor as low as 5450rpm. Prior to the engine work- I didn't hit this till ~57xx rpm. As for boost- i'm able to hit 8 currently might get 9 on an extra cold day. Time to look into re-scaling the maf sensor numbers again.

 

Just got my urd exhaust dropped off. Needs to be clean but will Probly have it ceramic coated once I get some resonators installed. It’s also forms double cab but needs to be cut up anyways.

 

You’ll have zero rasp and be more than happy ...

 

You’ll like that too. I did the same about a month and a half ago.
