2000 Pontiac Firebird V6

[WarShrike]

Figured I'd introduce myself, I'm in the US, visiting the boards for some quality V6 information and maybe some parts scavenging lol! I've seen some really impressive work on V6's over here both from COME/MACE/FIT and a few others. Also blown away by the Formula Holdens!

Car is currently down for upgrades/rebuild as it has almost 200,000KM on the clock! Started off as just an intake gasket replacement and cam install, but that was out the window when I pulled the valve covers to find a bad problem with oil sludge.

Hopefully it will last me another 200K!



Ran 15.86 @ 86.10mph in the 1/4 bone stock at high altitude.
Before the rebuild the car had:
Stock 3.42 gears w/ posi
Aluminum driveshaft
Whisper lid (intake housing)
Force Fed Fabs stainless longtube headers
Texas Speed & Performance Rumbler catback
32mm front and 19mm rear swaybars

Waiting to install:
Intense Racing S1X NA Cam
60*Inclusive hand ported heads and intake
Yella Terra 1.7 platinum roller rockers
TCI Super Street Fighter 3800 stall
other supporting mods and HPTuners

hey mate looks great.

[WarShrike]

Thanks, things are finally starting to come together after 6 months of just sitting in the driveway without an engine

[HRT 666]

Welcome mate, car is something different to look at and look forward to see what you get up to with it.

[MACE]

Nice ride
Shame the F-body shape wasn't available here at local GM/Holden dealer

[WarShrike]

I remember when I was in junior high (1996 or so) I found out about HSV through a race sim that had a mod for the Aussie V8 supercar challenge. I asked my Dad why we didn't have cool cars like that over here

[Zuicider]

can u get us sum pics of the engine?

[WarShrike]

Here's the extent of everything so far. Waiting on parts to get in and we'll get cracking on assembly!

ar just like an ecotech without the shitty intake

[Grennan]

Everyone loves nice and shiny engine parts

Love the targa top.

Yeah I found that weird... I knew they were a variant of the Ecotec, but its practically the same thing. Wouldve thought theyd make it special if it was getting put in a Firebird.

firebird would be lighter

[WarShrike]

Well GM toyed with using the Supercharged version, but they never put it into production, would have competed too much in sales with the V8. Woulda been nice to have a car in the 12's with a pully, tune and exhaust!

Actually, from what alot of us are seeing, the Holden plenum/manifold is better because of the intake runners. Our intake design isn't the best, and can run into issues for those with nitrous setups. I know a few that have gone to maximum effort setups with turbochargers and have put the Holden intake on their cars.

Best example is this one that ran 8s!

[Zuicider]

lol thats insane, so do u work in a rebuilding kinda layout do you?

[WarShrike]

I'm just a garage tinkerer, that 8 second car is from Tim King at Intense Racing.

I aspire to have a car with some of that potential, but his is just insane!

[vxcalais_01]

Ecoted are special . Your intakes to have better deisgns though, and variants, which is meant to be the reason why your ecotecs put out more power at the engine ?

So you guys didnt get the L67 in much over there?

[redcv6]

i don't understand, the l67 was used in many cars in America, most or all i believe were front wheel drives

[WarShrike]

L67 was used in alot of FWD cars, but not in the F-body. It would have competed with the V8 sales too much over here.

There is one guy who has converted a Camaro with an L67, he's trying to get all the loose ends tied up. He didn't have the Holden M90 which has a different angled inlet on the supercharger. The US M90's are a straight inlet, which would have had the throttle body in the firewall!

I was just thinking there wouldn't be much clearance!

Wow that would be a pain to do simple things such as change spark plugs....

[WarShrike]

Yeah, thank goodness aftermarket headers make changing plugs alot easier!

[Sladdo]

Thats a tight squeeze that engine bay!

[WarShrike]

Back up and running, time to tune!

[QUOTE=WarShrike;1495581]Back up and running, time to tune!

very nice mate

[red_vb]

sounds nice. looks good also.

[WarShrike]

Still trying to find time to tune, working full time plus school lol!

Had to install 130# valvesprings as the 105# ones didn't cut it and I feared I'd be getting valve float.
130's on the left, 105's on the right.



New license plate too
