02 WS6 build questions
i recently purchased a 2002 ws6 an im looking at throwing some more power under the hood. i am looking at getting a new MAF, Throttle body, intake, cam n valve springs, injectors, ported oil pump and headers. I also want ot put in a stall and 3.73 gears. is there anything else that i might need to pay attention to or replace while doing all this?

You should consider some head work, or complete replacements. Otherwise you are going to stuff and suck all the extra air through valve ports that weren't designed for it. Good heads will easily add and extra 30 horse to what the cam adds.

as far as head work goes it was mentioned to me to do a triple angle valve job and do gasket matching

here is the break down of parts i am looking at
92mm FAST intake
92mm FAST big mouth throttle body
Texas Speed Magic Stick 3 cam
FAST 36lb injectors
MAC exhaust headers y pipe n cat back with performance cat
K&N air filter kit
richmond gear 3.73s
oil pump? stock or ported?
other fuel system uprades? needed or not?
ingnition upgrades? have msd 8.5mm wires and ngk tr55 plugs
92mm MAF? any good brands?
looked into some ls6 heads and texas speed has a pair ported that i can have set up with springs for my cam. How much work goes into mating ls6 heads to an ls1? are they just bolt on or do things need to be taken into effect?

Upgraded Fuel pumps are also a good idea, but imho, not needed. Check your pressure during tuning, and that will let you know if an upgrade is in order.
LS6 heads are direct bolt on. Those are the heads I'll be adding.
I saw a good write up on spark plug wires somewhere, but can't remember if it was on here or not.
MAf is a good idea to upgrade with the intake. You want the whole intake the same diameter to provide good flow.
Good luck with the build! Post up some pics. See if you can beat me to the dyno

the car has 73000 on it so i will prolly get a new oil pump. I also want to freshen up the rings and bearings in the bottom end and re hone the cylinders. Im having trouble finding a 92mm MAF. 85 and 100s are everywhere. ill be ordering parts tues and starting work as soon as they get in so i will def be posting pics soon. THE RACE IS ON!

85 is a good upgrade. Every bit helps. Definately a good idea to do a hone, re-ring and bearings. I', hoping my cylinders are good shape so I can just go for a rehone and call it a day. You can see if you're winning by checking here:

You might wanna consider getting a Trick Flow heads and cam package.
12-08-2009, 12:08 PM #12
I looked into the trick flow packages while i was looking at cams. Have my heart set on
texas speed's magic stick 3. Nice rough idle and the powerband i want. As far as the
heads goes i was going to stick with just some mild head work but now im going to go
with texas speed's ls6 ported heads with PRC double springs. Thanks for the suggestion
12-08-2009, 03:00 PM #13
Aright So here is the final breakdown hopefully,
Complete MAC Exhaust System
TSP Magic Stick v3 Cam
PRC Stage 1 Ported LS6 Heads w/ PRC Double Spring Kit
FAST 92mm Intake
FAST 92mm Big mouth Throttle BodyTurbo
Turbonetics 100mm to 95mm coupler
TSP 100mm MAF Sensor
FTP 104mm Lid
FAST 37lb Injectors
TransGo Shift Kit
Perma Cool 16-18000gvw Tranny Cooler
Precision Ind. Vigilante 2600 stall w/ triple disc lock up
Richmond Gear 3.73s
Flatlander Racing Re-Ring Kit
TSP Ported Oil Pump
My Build up may be on hold till the new year due to scheduling issues for the machine
work in the bottom end. So you may have this one!

Weeeeellllllll, mine is on hold cause I just about broke my finger the other day removing a ground bolt from the back of the head. Smashed it between the air ratchet and the block.
I'll be back at it soon though!

In lieu of waiting for the shop to reschedule my machining ive been repondering my
intake options. I want to be able to ultilize the whole grille and ram air hood to allow
optimal airflow to a sealed box(when hood is colsed) that contains my air filter. I will be
equipping a 100mm MAF. I have been having some trouble finding an aftermarket
design that fits my application. Does anyone know if ther is one or is this something im
going to have to custom make?

I believe the only option you have that comes close to that, is the under car ram air kits that are available. The problem with the grill, is it's only cosmetice for the most part. Your bumper support is behind it, and will block most plumbing in that area. Aftermarket turbo kits usually require you to cut the center of the support and remove it.
