Hi, I am new here and was referred off TW forums. I am looking for the NST overdrive TRD supercharger pulley insert kit. I ordered a kit about 6 months ago and only recently found out that the kit is discontinued. I am looking for a used kit to purchase and possibly get some more kits into production. If you have one for sale please post here or PM me, ill be checking this thread daily. Thanks in advance!

The NST overdrive kit is hard to come by these days. You could get lucky on this site though. NST stop making them for a reason; and that's no demand. If you got tuning under control, changing the sc pulley to a 2.7, 2.6, or 2.55 is very easy with the snout cutter and a press on tool. Good luck:top:

thanks for the suggestion

Thank you for the suggestion, heres the exact reasons I want the NST kit:

I completely agree with you, the URD pulleys are very nice, and cheaper - but I already have the 2.55" pulley, and I still want more boost.

I understand I could change it out and put a turbo on it from STS or get the URD supercharger kit, but I live in california. Both these kits are very easy for a CHP or similar law enforcement entity to pop my hood and know its not legal, they pop my hood and see a TRD supercharger with EO #'s 99% of them have no $%&*ing clue how to determine from there if the supercharger is modified etc, and therefor will most likely move on to the lowered honda idling by on the I-10. (yes I live in LA).

Already having done the 2.55" pulley - the only way to make more boost with the TRD supercharger is a larger crank pulley insert. (my understanding is machining down the snout any further will seriously compromise the integrity of the supercharger snout). I also realize I could have the supercharger regeared but thats thousands of dollars and most likely will be un-reversable.

So here I am - WTB NST crank pulley insert kit :) There must be others out there that are also interested in this kit or option and thats my plan, I want to buy a used kit and then make some more. I already asked NST if they would be willing to do a limited run, or just make me a kit, they wouldn't even entertain the idea or give me a price quote. Money is not the issue unless the pulley kit is going to cost more than my other options (but again my other options are also easily noticeable as not street legal in california).

having already done the 2.55" one would think you're really pushing what the TRD's efficiency

Too much overdriven and it turns into a heat pump

IMHO, FWIK

That is correct, but I'm not at that point yet and the 7th injector + E-85 definitely pushes the efficiency threshold a lot further out. If I run into that problem I can also start running C02 sprayers on the supercharger radiator behind the grill to bring intake temps back down. Could also add an external oil cooler for the supercharger if need be. (scion tc's run an oil line to their TRD blowers), would only require an external oil pump such as one for a turbo charger and an external oil cooler. Both of which are smog legal - no laws saying I can't spray C02 on my radiators, no smog laws against an oil cooler for the supercharger.

I am not your average bear, I have put a lot of thought and research into this. Really the only option for my specific application and requirements, is the NST overdrive kit. Im an ASE advanced level specialist, and a smog technician so both of these knowledge bases have also been factored into my decisions. I am more than willing to answer any questions, I just don't want to keep telling everyone and their mothers about why I want to / need to do this instead of other options. I am set on this decision, unless someone wants to buy me the STS or URD kits and pay for the fines when I get pulled over then this is the direction I am trying to go.

If you are really serious about this and cant find the kit, get ahold of all the pullys that are stock but would be replaced with the NST kit. Sit there with some callipers and reverse engineer them. Choose where you want diameter reductions or not. Do up some drawings and research bearing sizes as well as press fit standards and have someone machine them for you. Not the easiest way but definitly effective. If you have access to a lathe and are good with it you could probably do this on your own.

So you are currently running the trd supercharger with 2.55 pulley, 7th injector, e85 all tuned on a unichip? If so, you have to be the first... What injectors are you running and whats your rev limiter set at? Have you thought about a larger heat exchanger, reservoir, and intercooler... Got any pics?

As for the e85, are you using an ECA to work with the unichip?

You could always tear the supercharger and install ceramic bearings inside. Wonder how much boost he is currently making. Has to be close to 12psi im guessing

driving

Depending where I'm driving I get anywhere from 11-12 psi of boost so the gauge says. Im running a regular unichip with an extra driver module for the 7th injector. I built my own 7th injector setup using this:
http://www.billet-speed.com/fuel-injector-holder/
Im running 6x siemens deka 60lb injectors in the main ports soldered in with new ev1 pigtails, and an 80lb siemens deka in the 7th injector setup. I chose to run this way because of the throttle body adapter setup both URD and APR use, I already have a throttle body adapter from urd for the 5.7L tundra / sequoia throttle body. Bought the URD fuel rail tap and built some AN lines from Russell parts found on Amazon. I do have an E85 sensor but I'm waiting on some fittings to tap it in on the return line and hook it up as an input to the unichip (got a 0-5v linear output specifically for this), the reason I am actually running the unichip is because from what their tech guy says I will be able to hookup the E85 sensor and have the unichip switch between 5 maps seamlessly while driving dependant on inputs. The URD computers from what I can tell have two major downfalls in my eyes, I realize they are much more end user programmable, but they only have 2 maps to switch between from what I can see, and although gadget is working hard we have yet to have a plug and play harness for the 2012 tacoma prerunners. Also from what I can tell theres a debate over whether or not APR x1 (good luck finding one right?), the econ EMS and map ecu 3 can control the air injection properly. Although the unichip is simple, it works and its plug and play.

Ill take some pictures later and post them if you all are really that interested. I'm also waiting on some radiator hoses to put this 79-93 5.0 mustang 2 row 3" thick all aluminum radiator in, I have been looking at new heat exchangers for the supercharger but haven't quite grown the b*!!s to buy one and figure out the mounting of it (I know funny when Im replacing the radiator, but its true.).

Nice to read this. I took a chance on the Unichip as well because there isn't anything else available that was pnp. I also bought the tuner software so I could tune it myself. I have it installed and have really not strayed from the standard maps yet. You cannot. Also use it as a security system which will prevent the vehicle from starting via a map. Anyway, I will be picking your brain Toyota Tech because you are already ahead of me in building using a Unichip. Hopefully I can get everything out of the Unchip that the manual says you can, so far I have no reason to believe we can other than what DoubleD mentioned, which is using maf vs map and stuff like that...

I dont think Co2 will work on a water to air cooler.... You will have to drop the temp of the water with ice.. There is too much water to cool efficiently or you would have to run the co2 for a long time...

I know you said you were in cali but another way would be to hide a nos jet in the snout of the sc

I've been running filtered water and RP Ice for my intercooler system. I still can't believe only a quart of liquid is used here. Water is such a better heat displacer than Toyota pink coolant.

Anyway, glad to see Toyota tech thinking outside the box:top:

Im making a build thread ill have it up in the next few days as I am truly just finishing it. Need to clean a few things up where I have sensor wires and stuff all over, Its almost in somewhat presentable condition although the oil cooler looks terrible. Ill get some pictures posted and a few write ups since I don't see any other custom injector setups on here.

Still Looking For NST Pulleys! (Have the CR-Lite Set, Need overdrive for TRD SC). Offering my firstborn.

Well wouldnt a bigger tank for the SC heat exchanger help with temps? I know that subaru use to run a water sprayer on their innercoolers. I wonder if something like that can be done on the aftercooler on the trd supercharger. I know they make a snout cooler for the oil although im not sure how hot that oil gets. I do know that the blower under WOT for a long period of time just heat soaks the crap out of it

^^^the heat exchanger has always been cold to the touch from my experience, the inter cooler however is the main culprit. With 3D printing on the rise there could be made a larger inter cooler to swap out for the factory trd yet still have the same bolt pattern

Nice!!!!!!!!!!!:top: i was thinking of running the 2.55 pulley but i was hesitant...
