k so im about to order the trd s/c for my a/t tc and i was wondering...should i get anything additional? do i absoultely HAVE TO HAVE a boost gauge? and i already have dc headers....an aem cai...and tanabe concept G axelback...will this affect the install at all when i go to toyota?

 

You don't need anything additional. You don't need boost gauge。
I have S/C, and don't have boost gauge.
You might want to take off the CAI and put back the stock air box. Because dealership might charge you extra labor for remove the CAI. They charge me to remove my engine dampener.
i also have dc header when i went to the dealership, i told them not to install the heat shield.

Good luck with your SC.

 

to keep the CAI, it will take some modification. You won't need the boost gauge, but it might come in handy later if you use a larger pulley. I would however recommend, as it was recommended for me, to get a wideband A/F ratio gauge, and and EGT gauge to monitor for leaning out at WOT, and possibly an oil pressure gauge.

 

To my knowledge, you can't use the AEM CAI with the supercharger unless you chop it up to fit.

Of course you don't NEED any gauges, but how will you know if you're running right? Something could go wrong and you'd never know it until it actually broke.

 

You might want to take off the header and get it wrapped or jethot. Also, they might not honor your warranty if you have one on.

 

You SC warranty will not be honored if you have an aftermarket header and CAI on it. They will be able to prove a direct relationship between the failed part and the failure (if anything goes wrong).

This is what they'll say:
Header - Heat can destroy bearings or other SC components
CAI - changes the A/F mixture, which could contribute to almost any type of engine failure. They can also say that the CAI doesn't do as good of a job of filtering the air coming in, which can cause about any type of engine failure.

I'm not saying that you will experience these problems, but if you do and have aftermarket parts installed, you will not get warranty coverage.

 

thanks guys... ok well from what ive heard from other people...if i have the cai...it could cause my car to run lean when the s/c gets installed? is this true? so I SHOULD/HAVE TO take the CAI off?

 

^yes

 

It will cause your car to run lean. There's no "could" about it. This is why:

1) An a/f gauge is a good idea

2) An ECU management system is a good idea

 

Since you are A/T you will need the Automatic Transmission Super Charger Fit Kit p/n PTR01-21051

 

k well dont superchargers usually come with the fuel managment system already? and also i found out that the only place u can get a reflash is from toyota...another 100 bucks! ok well wont the reflash take care of the "lean" from my intake? or do i still n need the fuelmanagment system? and where do i get one from for my supercharger?

 

It would take care of your engine running lean... if you weren't running a CAI. Here's why:

When the dealer reflashes your ECU, it assumes that you're running with the TRD airbox. When you hook up something that brings in a lot more air, it can't compensate for that by itself, so you start running lean. You need an EMS so that you can make the ECU compensate for it.

It's a good idea to get both, simply because over time, your ECU will start adapting to the EMS tune and eventually revert back to it's default state. It's much safer for you and your engine if it reverts to the TRD tune instead of the N/A tune.
