The 3.4L TRD Supercharger Thread

[Black798]

I guess your truck really didn't like them. It's so odd since they are a well known fuel upgrade that's been around for years, I mean even Gadget had them in his 4Runner before he started selling the kits.

How does your piggyback adjust ignition timing? Is it done via the igniter circuit instead of the crank sensor?

It's a well known upgrade but based off what I've experienced with my truck there's also a large percentage of guys running these setups "tuned" that really don't have a full understanding of everything going on and say "it runs great"without really understanding of everything is working properly. Imo running one of these without a pyrometer and afr gauge is just asking for issues down the road. The 5vz is an incredibly hardy motor that allows a lot to think "well it didn't grenade instantly so it's fine" but it suffers from the same tuning issues as any other and without proper monitoring and tuning. It's one thing to make power for 5 minutes it's another to make it for 15 years and not cause damage to the motor.

It's just like the 7th Injector and my gripes with that system. It's proven but I do not believe it's the safest way to tune this setup nor is it the most powerful.

My piggyback is tied directly into the igniter circuits. By some black magic that's how it allows me to both advance and retard the timing

Welcome to the club!

These superchargers are pretty easy, slap it on and go. Having the 2.2 pulley does change that a bit but depending on what elevation you are at you may not need to change the tune much at all. There are different tunes but the Toyota ECU cannot be flashed so it has to be done via the 7th Injectors software and interfacing with the box in or behind your glovebox.

Boost gauge is just for show, wideband oxygen sensor with an air/fuel ratio gauge is a must if you want to tune it though. No way to do it if you have no idea how rich or lean you are running. Seeing how much boost you are pushing is irrelevant for a S/C vehicle (not like a turbo) except for tuning purposes, but your air/fuel ratio is critical for making sure you're not running lean when you start modifying.

Ok thank you for the info, as for elevation im at sea level. I really dont want to tune anything if its not needed. The PO tuned it and did all the work and said it ran better than his tacoma did with a SC. Now whether thats true or just a line of BS idk. Overall the truck runs good, no hesitations, hard starts, sputtering, rough idling, trans shifts great etc... Gas mileage could be alittle better lol but oh well.

Yeah there's a lot of subjectivity out there and a lot of people who just "consume" vehicles. A mechanic was working on my car once and shared he had a S/C Tacoma and burnt the valves and recommended me taking it off mine (lol). He then went on to say he was always gunning it around town at every chance he got...

So, I just picked up a second gen(black) supercharger from a guy that bought it new 6 months ago and now needs the cash.
The kit came with everything I need except for the TB gasket... I've poked around and haven't found a clear answer on where I can get one... does anyone have a link to spot where I can get it?

I know on the first page it says to call Magnuson, and I've not done that yet cause it's late on Friday, but is there a place I can order one?


Excited to be apart of the S/C gang.

URD Sells them, or cut the metal one and make it round...thats what I did

I just Googled "3.4 supercharger throttle body gasket" and the first link lead me here
URD Throttle Body Gasket for 5VZ-FE O-Shaped - Underdog Racing Development

I think I found it in under 45 seconds. (sorry, couldn't resist being a prick)

Good luck and welcome aboard! Keep your wallet out... You'll need it

Be whoever you want to be, googled the same and got a result saying it was backordered a few weeks from URD... Magic of the Google search and localized availability based on of search. Glad you found it! Enjoy your weekend.

Wait, that made it sound like it's not available to you?/for your area? Do you want one of us to order on your behalf and then send it to you? All assholing aside, I think every owner of a 3.4 should be able to supercharge it. That's shitty if this gasket is holding up the show.

Let me know if I'm understanding this correctly and you'd like me to attempt

1st gen nose cone rebuild - tension spring?

Ok, so Im just about done rebuilding the nose cone...on my gray top...but i realized that there is no tension spring in this nose cone...and in all the rebuild pics I have seen regarding the gray top...there is no tension spring. Only the black one has the spring. Is this correct? Or should I order a spring and put it on mine?

Truth on keeping the wallet out. My blower install has gone from small dollar investment to not so small dollar investment. :Cry:

The hole opening was about the size of a wd40 can base...i lined it out and used a dremel to cut it. took all of 5 minutes, which included polishing it up and cleaning any burrs off. Now its a reusable metal one that wont tear, and was cheaper than the paper one. I think $6 shipped from ebay

LCE Performance offers a few different options for that gasket too. I am running a teflon one from them. I like it.

I appreciate that. I was able to order one.
That was the final piece of the puzzle I believe.

At this point I am not planning on running any fuel mods, and am still on the fence about which plugs to go with.
I have read a lot of this thread, not all but a lot, and done some other reading. Some say don't worry about plugs unless you're doing fuel mods, some say you have to do at least one click colder, some say two. Not sure I've made my decision yet.

either way, 4runner is getting oil, air filter, and once I'm through this last bit of gas a tank of premium and a new fuel filter - then I'll do my instal.

 

[4Reak Show]

Nice! Plenty of folks have ran standard plugs with the SC (myself included) and it was fine. I would recommend a larger fuel pump at some point, so at least there is sufficient fuel available for the stock ECU to use if it so desires.

If you add a 7th, you'll certainly need the fuel pump and plugs. Otherwise, you'll be just fine. Only recommendation is to keep an ear out for the ping and avoid those RPM's/load conditions.

Have you guys never heard of rock auto ??
They have everything that will need to swap your sc on.
I know most guys like to use OE only but me personally i don’t care.
But rock auto does have aisin, koyo same stuff the factory will sell you and charge extra for cause the box says toyota on it.

 

[Rockdawg84]

well I'm pretty sure that my Walbro fuel pump that came with my 7th injector setup is taking a dump. several days this week I had trouble starting my Runner and it was acting like no fuel. Once running it seems to do OK but something is off, like Its just a little underpowered. Also the pump has been louder than normal which is saying something. So I'm going to replace the pump but I really want to go back to a Denso pump but also want the greater flow rate. So I think I am going to try a Mazda Rx7 turbo fuel pump. Similar size and flows 223lph. Part number Denso 195130-0782. Has anyone used this or a similar pump. I'm running a 2.0 pulley boys pulley and am hitting about 12-12.5psi max boost. I am running the URD preloaded maps. I'm interested in your thoughts. :tea:

I didn’t think to look at Rock Auto for SC stuff. Not a bad idea. That said, I’ve had some bad experiences with them in the last year or two so I’ve pretty much stopped using them.

So i have been away working for the last month and half and only just got back to the house to look at my new parts...

I had purchased a used supercharger online and when it was delivered, the packaging was obviously not adequate. One of the components and bracket were bent and broken off.

Does anyone know the part number for this?
Is the rod supposed to be straight? can I bend it back?
Can I JB weld the canister onto the bracket?

I was able to bend the black bracket back into a straight position, but the canister looked as though it was riveted in place.

if anyone can provide similar pictures of what this is supposed to look like it would be greatly appreciated. thanks ahead of time.

Yeah it should be straight. Get it close and it'll probably be fine.
