picked up the new car today. 1998 pontiac formula ws6. hardtop, cloth interior, M6, 63000 miles. BONE STOCK. this is the way the car came in 98. its bright red and has very few scratches. garage kept. that is true, this dude had the facility to keep it in. no rips in the seats. runs and drives like a top. he ran a 13.6 on F-1's and some bilstein shocks. he was into road racing and the suspension is as stiff as a kob. he only had it to a road cours 3 times in the last 6 years. not ran too hard. Nothing like my old car was run. First wave of mods are as follows:

wave 1
qmp turbo kit
ls6 intake
new clutch
6.0L stock heads
pro 5.0 shifter
sub frames

wave 2 Suspension
12 bolt
lca's
torque arm
drag lites w/ sticky tires
hal shocks

Any other suggestions would be apprecitated.

How much boost do you plan on running? your going to need some fuel too, with good tuning

not sure yet, i need to find out what my comp. ratio will be, for got to mention the 340 intank that i am getting with the kit, sorry. how much boost is safe with that set up?

BIGBOS

I would get twin 340 pumps just to be safe, you'll end up getting them anyways in the future or something more serious than that, but that will carry you a far ways.....

I would get 42.5lb injectors for now if you are going to be in the 500-550 range for power with 7-8lbs of boost......on pump gas.....

Get some 73cc chamber 6.0L heads, that will drop the comp ratio down under 9.5:1

KAOS

with 9.5:1 how much boost can be safely ran on pump gas, no alky injection, yet. also the kit is coming with 42lb injectors, its WARBIRD's old kit

BIGBOS

You could probably get away with 10lbs, not sure what kind of power you would make, what turbo will you be running?

Tuning is key

KAOS

t-74, with .96 a/r, sounds like you are saying tuning is the key for FI cars

BIGBOS

Yea, the tune can be pushed pretty far, but it all depends on how long you want that 60,000 + motor to last......

Robs car is making some sick power on stock heads/cam

KAOS

iTrader: (5)

i know that thing is awesome, not sure i will ever make that kind of power or not but it would be fun trying. for now that motor has to last a while. like for it to be a pretty safe tune. also will a stock MAF work or should i step it up. i am brand new at this game and Cannibals brother will be helping with the initial tune, hes pretty good but he has only done NA cars, how much of a difference is there. All input is greatly appreciated

BIGBOS

Tuning F.I. cars takes some work, just needs to work with it I guess and make sure the AFR is in a safe range, I would start with 5-6psi then work up from there, you should be able to see how far it can be safely pushed on a 93 octane tune

Get the Racetronix Fuel pump, Daniel.

Also, I'd get those sweet fuel rails from LS1Speed.

Here are my comments....

Just get the Lou's Short Stick, that'll save you from having to buy the Pro 5.0.
Clutch - Spec 3, do this as one of the first things, get it broken in and ready to go, I don't think the stock clutch would survive more than a few dyno pulls on the QMP kit.
LS6 Intake can be had on E-bay for $279 I believe + shipping.

6-Point Roll Cage
Moser 12 Bolt (Ask Rob or someone what gearing for the FI you're doing)
Denny's Nitrous Ready Driveshaft w/1350 yolk
Torque Arm
Drive Shaft Safety Loop
QTP Cutout
We can make your own LCAs with the QA1 XM ends, same goes for the PHB
Airbag for right rear spring, too
Boost Gauge
Fuel Pressure Gauge
Dual Pillar Pod

Finally, have Rob dyno tune it for you to safe tune. I'd say with a good, safe street tune, you could put down at least 600 RWHP, no problem. Then if you want more later on, get an APE cheap street 347 forged short block.

I think your shifter is a personal choice. I've driven a lous SS and didn't like it. I have a Pro 5.0 and cut the shaft down and it's perfect. You definitely don't want to use a stock shifter, lous or no lous. Get the Pro 5.0. I'd also consider throwing the rear into wave 1. In a 6 speed with as much power as you'll be making it's gonna die a quick death. Clutch, I'd say Mcleod SDK(if this sees occational track time) or twin disk(for a more serious track car). You could also probably put the LS6 in wave two. It's helpful but not neccessary. Clutch, Rear, Turbo, and most importantly fuel is what you should focus on in the first wave in my opinion.

car is going to be at the track but more on the street, fuel pump is coming from racetronix, warbird is going to get it for me and send it with the kit. rear will hold up on the street not at the track i know. goal is to get everything up front fixed first then the suspension, up front includes fuel. thanks for all the suggestions, keep them coming

Go to hell, I already have that designation my car is 'CHAOSS'

6L heads (4 inch bore) arent the best choice for a 3.90 bore engine. Might want to reconsider that.

I would run stock heads and can and throw in good springs (02 LS6 springs would work fine)

Put the money into the fuel system now. big injectors (at least 50#) and good pump.

Put money away for a proper tuning session and eventually put more money away for a rebuild down the road

oh well. asked ls1tech to change my name and they did, formally daniel2002TA. that set up is gone and this is the new one. tough luck it sounds like. but that is not wha this thread is about. its about helping out a newbie to the FI world.

BIGBOS

I'm running some 5.7L heads on my bored out motor, the 6.0L when I wanted them were on backorder.....didn't feel like waiting.....

I had the Pro 5.0 with my 6-speed, that was a badass shifter.......

KAOS

want to get the CR down a bit to throw more boost at it. Talked to Rob and he mentioned your 6.0L "budget" heads to me. sounded like a good deal to me. can i get the compression down with 5.7 heads? if so let me know.

BIGBOS

I have TEA S2 5.7L 73cc chamber heads, got them for around $1600
