NOS is overrated Yes it is INSTANT HP. However it is way to hard on Pistons and Rings. Your setup is not right your looking at 5K Overhaul for an engine to accept it. Now with a Turbo it is Free Power or Supercharger you can put in a Popoff Valve and never get above say 10PSI and not have a problem. Sorry talking to someone that setup motors for NOS.
They only burn up pistons, rings and spark plugs if they are set up too lean which generates too much heat. A fatter mixture keeps combustion temps down and avoids burning stuff up. There are 5.7 Tundras running a 150 shot on the stock motor. The Toyota 5.7s are pretty tough from the factory. Forged pistons and crank. High strength connecting rods and rod bolts.
You just have to read the plugs and adjust mixture accordingly. It would be nice to be able to retard timing a bit, but I am not afforded that luxury. Toyota locks down their ECUs very well. I'm going to set it up rich and monitor it with a wide band 02 and AFR meter, then begin leaning it out until I reach the right mixture.

I never pictured you driving a toyota!!
A 390hp/410lbft Toyota...before nitrous.
It'll run a 14.36ET at 95mph as is.....4doors and a camper shell. (roughly 5800lbs) The juice should put me into the 13s.
I installed a McGaughy's 2/4 drop kit at 4K miles and added Lakewood traction bars. It now has 285/60R18 Coopers all the way around.

Do you have any plans to actually put it on the track?
 
Are you running the nitrous off the stock computer or did you get a new system? (asking this for my husband. He is installing a turbo setup on an older Tacoma for a client - I think it's a 2002, and he needs to find a computer setup ot run th car. The guy brought it to us with Haltec, which is garbage so he's desperately trying to find somthing else. )

I made a few passes at KCIR over the smmer. That's how I know what she'll do.
 
I am planning on using it with the Toyota ECU and an URD MAF Calibrator. I'll monitor Air/Fuel ratio with a wideband O2 sensor and A/F Ratio meter. I think you can also replace the upsteam 02s with wideband sensors for faster input to the ECU. The 5.7s run rich from the factory, so I'll be leaning the mixture out a bit with the nitrous.
If your husband is doing a taco, get in touch with Gadget at Underdog Racing Development. He is the go-to guy for performance Toyota trucks and SUVs. If it's a V6, there are TRD superchargers for those trucks that are easy bolt-ons, and I think Toyota has flash programming for those applications. I would do a roots type charger on those before doing the fab work for a turbo.
For a complete engine management system, I would contact MOTEC. Does it have a manual trans? That would make engine mgt easier...not needing inputs and outputs for the transmission.

I also ran a cold air duct from the right hand fog lamp delete trim to the inlet on the factory air box, installed a K&N flat panel, removed the charcoal filter that lives under the airbox lid and insulated the ductwork under the hood.

my wife wouldnt like that at all. If I came home with that she would do 2 things
 
1. laff at the thought of attaching nitrious to a mozda protoge
 
2. divorce me as fast cars + me = really bad news for us and great news for the state and ticket income.
 
I seriously think this is why she agreed to allow me to have a sw tank and not the '72 corvette that I wanted and found for sale near our home.

Just leave it in the living room. When things get boring, crank it open for a while!

all throttle no bottle.
i just would not trust one of the solenoids from hanging up.if one does especially the fuel one there goes the neighborhood.i dont know anything about the forign vehicles but can you just get a piggyback fuel curve computer for this truck?
i used to have a 1973 olds 442.455 motoe with a 6:71 on it.4:10 gears and a 3500 stall.scary car .i sold it for a dump truck to start my business.sucks growing up.

Huffers for these are $5-6K including dealer install with reflash.
Piggyback fuel control is not an option. The trans is a 6speed electric shift automatic that relies on the ECU for shift commands. Toyota locks their software down VERY tight. DIablosport has been working on a programmer for these trucks for a LONG time. Still nothing. For $150, nitrous is a viable option. With a piggyback A/F meter and wide band 02 sensors, I can watch for changes and let off the button if she goes lean.
Here's the TRD huffer... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=140456921342&crlp=1_263602_263622&ff4=263602_263622&viewitem=&guid=ea9b2bd612a0a0aad1e4d794ffd342b2&rvr_id=147741725088&ua=WVI7&itemid=140456921342

Reading this really shows how much things have changed in the last few years when it comes to improving performance. I built my autocross/hillclimb/trackday car about 5 years ago the hard way. I went with a shaved and ported head, bigger carb and cam, header, lightweight flywheel and a better ignition, then started shedding every bit of weight I could with door, hood and trunk skins, delete bumpers, no carpet, no passenger seat and the list goes one. The car at that point was still street legal and a ton of fun to jump on people with, but miserable to drive because the peak power starts to happen at about 6000 rpm so basically I have about 1500 rpm of usable power. I have since pretty much stripped it and it is no longer even close to street legal which means it sits in the garage all winter taking up space which is starting to bother me a bit.
Bolting on a supercharger to a new vehicle in a day sure sounds nice compared to spending two weeks just trying to dial in cam timing after I had my head shaved.

Not much has changed in 5 years...maybe some engine management sotware, but Motec has been doing stand alone engine management for quite a while, now.
Don't forget that we keep the Toyota Powertrain Warranty when installing a TRD supercharger. If something goes south, Toyota fixes it. We keep our carpet and have a powerband that runs off idle to 7K rpm. Nothing wrong with building a car...don't forget I also have a '57 Chevy...but why chop up a car when we can bolt on 150hp and 150lbft creating a near 6,000lb truck that will turn mid to upper 12 second passes while still having room for 6 people, a load of 4 wheelers, and pull a travel trailer? The S/C is my first choice, but for $150, I can make nearly as much power at the touch of a button.
You mention timing the cam after milling the head. Degreeing the cam should have been pretty straight forward. It's something that every race motor should have done, regardless of having material removed from the head. What were you building that had an overhead cam and carburetor? An old Ford 2.3 mustang?

Yeah, the fact that Toyota lets you have a supercharger and a warranty is a huge selling point and a 12 second Tundra is really awesome sleeper.
Degreeing the cam was pretty easy after I bought a degree wheel, got some better instructions, fixed a bad wire in my ignition and got my Weber jetted correctly. The motor is a 1.5 SOHC Fiat in a X-1/9 that I built out of the parts stashes of all the people in my club. It is not the older Fiat motor that ate the valves when the timing belt broke and so far has been extremely reliable for racing.
That old 2.3 Ford motor was a good one too, it was the basis for a ton of race cars, but all most people remember is the Pinto. I'm pretty much all over the place when it comes to my interest in vehicles. I have my sports cars, but I also recently finished restoring my old Ford truck and the motor in that is so nice I could just drive it all day and my wife has a really nice Mustang and after I recover from the ding my savings account took for the last 3 years while I have been working on my truck, we both want to find a 64 Mustang and build a inline six using Clifford Racing parts and mate it to newer 5-speed, do the disk brake conversion and also upgrade the suspension while leaving the outside looking stock.
