I will be doing a cam swap soon on my 01 Z06, the car has headers and a Halltech already. I have a fast 90 laying around and a extra LS2 90 TB. My question is this a good upgrade, and will there be problems tuning it versus the stock size TB?

 

Not at all, as long as it's going to an actual tuner. I take it you have the appropriate harness already to run the ls2 TB?

 

No, but going to ck with caspers to see if they have a wire harness.

 

If your tuner questions the intake/ throttle body-----you are going to the wrong tuner

 

Nope, don't have a tuner, Just trying to get all my ducks in line, before I make the switch.

 

I posted the info below in a post earlier this week and it applies to you also. You can just slap a cam into the engine and it will work, BUT,, it may not work correctly, last long and be really noisy.. So,, here is what I can input:


Your wallet is going to HATE YOU!

I did ALL the stuff that your going to do.. So, that being said:

I did my 02 ZO6 with the following up-grades: Patriot Performance Stage 2 Heads, Cam,Home ported Fast 90/ported 90mm TB, Stainless Works 1 3/4 primary LT SS headers, 3" mid pipe/mufflers VARARAM and ALL the supporting STUFF and a very good tune.. She made 450 RWHP.

Here is what you will need. If you cut cost, the quality and dependability of your build will suffer!

New Quality Lifters!! Most use LS7 and are happy. I strongly recommend NOT using your old OEM lifters!!

New Lifter trays!

New Pushrods!! MEASURED with a push rod length checker!!!!

New Rocker Trunions/ COMP CAMS Trinion Kit

New Rocker pedestals (Things the rockers sit on)

New valve springs and Ti Retainers

Higher compression ported cylinder heads

New high volume oil pump

New LS2/LS7 timing chain or better
LS6 Style timing chain dampener

The correct CAM (we can discuss the specs later)

LS2 Throttle Body with the correct conversion harness.

New Higher flow injectors!! I used 42 lb/hour but 36 lb/hr may work for you

PROFESSIONAL TUNE!


I have a Ported FAST 90 and I home ported the manifold and the TB. Works fantastic! Im NOT loosing any power because of the manifold and neither will you! Excellent choice!

RECOMMENDED UP-GRADES and IMPROVEMENTS!

You dont have to have the following BUT,, knowing what I know now, I wouldnt do the job without them:


ARP Head Studs! Trust me,,, you will thank me after your done!
ARP Dampener Bolt
NEW OEM Dampener or UP-Grade to a powerbond dampener.
Pin the dampener to the crank
Oil Pressure sensor relocation kit
Ceramic Coat your new Headers!!!!
New GM Red Performance Spark Plug Wires

Replace the coolant passage block off plugs on the rear coolant crossover passages with a 2001+ front pipe to gain that steam vent for the heads!



As I was tuning my car on the street, My OEM 50,000 mile clutch started to have issues. The clutch peddle will stick to the floor under full power runs.

New clutch Master Cylinder (OEM is fine) unless you replace the clutch.

Install a remote bleeder on the slave system and flush the complete system

I installed a $1200 SPEC Dual disk clutch, new TICK master cul, new slave, new pilpt brg, new throwout bearing and aremote bleeded. My bell housing was cracked so I had to install a new bell housing.



I wanted to up-grade my drivetrain so,, I did the following to the differential.

I also changed my OEM MN12 transmission to a C5 converted TRANSZILLA T/60/60 trans with a hardened output shaft

I disasembled my torque tube and inspected the rubber couplers. Mine were fine. Yours may not be. Better check!

I probably missed something. Its a SICKNES that just keeps getting worse!
