ours are steel, but it's not that easy. You want the scrapers to be about .030 from the rotating assembly. I don't suppose anyone out here sells just a scraper kit that you can bolt on? Aren't your engines mounted like ours? with the belt towards the front bumper of the car? How does that oil...

I'm curious as to your setups on your oil pans on your Holden 3.8L motors. Do you guys have an aftermarket for oil scrapers for the crankshaft or better windage trays? I saw a thread about an ASR (or ACR) oil pan, but because of the square piece at the front I am almost 100% sure that will...

Heads have been port and polished locally, they have 1.9 intake and 1.57 exhaust valves (manley's) The compression is roughly 9:9:1 on this motor. The cam is a custom ground cam 230/240 .512/.512 113LSA. A full list of my mods is here There was a few guys that tried, irrc stroking these...

Thought you guys might be interested on some progress with the "American" 3.8L version of your motor. I haven't been to the track since 2010, and still have a few bugs to work out of this setup. Best time is a 13.4@ 100.77mph in the 1/4 mile....I still havent got my holden intake manifold...

Not true, my buddy backed into a fence with his Honda Odyssey and its like a tanish silver metallic. We did all the steps up until applying Quixx to his van and its still pretty hard to see from far; and his scratch was long, fat and deep. I can't wait to see the end result. I'll take pics of...

ya, I kinda kick myself to because the weather was nice for a little longer and I kept it out an extra week rather than just pulling out the beater. I would've been a lot less pissed if it was the beater this happened to.

I poke my head in and lurk here every so often, mainly nabbing info on your Australian intake manifolds...figured my write-up might help out any of you that have gone through the same B.S of having your car keyed, or just the headache/wear and tear of scratches. Long story short, just before I...

Well the plan was to make some sort of removable plug for them if possible...leave room for juice should I ever decide to go that way, or something like meth. In what sense do you guys think the pcm will go ape ****? Just curious? This has been one of my unknowns for awhile. I believe the IAC...

I'm not understanding where the radiator is coming into play here? The computer cools the car based on the ect readings at temperature (A) it will kick on fan #1, at temp (B) it will kick on fan #2...your water pump is belt driven or electric if you've upgraded like I have...this means your...

I hate to burst anyones bubble and sound like a dick, but no way are you going to get an ITB setup to run on a stock tune...the LS1's over here that have these setups see 60rwhp OVER the fast 90 intakes...you would be retardedly lean on a stock tune. And those tbs could be for either or, quad...

These are the tbs that I have broken down and started cleaning up, well 4 of them anyways....guess They have two injector ports which I plan on blocking actually. Notice the double nipples on them? thats what is going to go to your vacuum canister. The back side has the set screws in...

TPS would be on 1 tb, and all tb's are tied together via the linkage. IAC, I know atleast with motorcycle TBs there is a screw that you can open and close to determine how much air you want to leak in past the butterfly.

that diagram you drew was more or less my thought of doing things, except instead of the flutes you speak of, run a nipple off the top of the tbs into the vacuum canister...your vacuum booster will take from the canister, as well as having your map sitting on the canister as well. Problem is...

they ever find out what caused it? the turbulence? thats why I was thinking 6 compartments.

my thoughts on this...I think 2 tbs on each side without seperating the manifold is going to cause crazy amounts of turbulence. Now I had a few thoughts for making an ITB setup, I think the best way with the holden manifolds would be to split the tbs into 3 per side...like this Just...

has been shitty weather, so I haven't attempted to go nab my car from its shelter lol to pull pcm numbers. Other than that, Im just hear listening to other people throw ideas around and throw my 2 cents in every now and then. I can't do much about the intake until I get my tranny issues sorted...

good read, Im very tempted to use bike tbs for ease of use...but 4 tbs on a v6, people are gunna think I'm definetly retarded. As far as the TPS goes, what about using the existing bike ones? I think they are a 5v wire as well? if not, maybe there is a plug in/resistor or something that will...

$220 each? :rofl2: Buy a set of 4 off of a bike...they come in a million sizes and cheap, I have 8 sitting in my basement that I got for $160 that I've been playing with...Hell, I've contemplated just slapping on some haybusa or gsxr 600 throttlebodies (all 4 in a row and not breaking them...

well stock size tb is what? 65mm right? so a 65mm tb will have an area of 10,414.20mm a twin 55mm throttle body will have an area of 14,912mm so essentially you can flow alot more air. A triple 55mm tb setup would give you about 22,368mm of area allowing you to take that much more air into the...

see, my map based tune works fine the my huge cam and modded heads car atm, but Im tricking the system, skimpish is running the same tune that I have, but modified to his motor (atleast he was)...for us, the VE is maxed out at 200% at WOT and we need to "cheat to attain our tuning goals) I dont...

my main concern is tuning as well...You need a MAF to get a reading for timing and see where you are getting KR, and it would be difficult to run a maf unless you did one on a collector tube that fed into the 3 throttlebodies, but I think that restricts how much air you can get into the motor...

not total max size, like (3) 55mm throttle bodies...if my math is correct, that will give you an area of about 22,368mm If you went with a bigger single 65mm throttle body your total area would be 10,414.2025mm. But air is going to flow alot slower through that bigger tb. I dont have any other...

Im not sure what size they were to be honest, If I had to guess I would say you probably shouldn't make them over 55mm each if you are going to go triple's... Here is a picture of it, I think this would give you the best distribution of airflow.

Ive never had an issue with lockup like you suggest...although the car does rev a tad higher to get into gear when it is cold. Make sure you tune out the pwm parameters as well, or that will damage your converter. I dont know what your other guys holden pcm programing looks like, or if you...

Go with a higher stall...grab something around 3200 rpm...its only going to slip up on you around town starting up...once you get driving the converter locks up and and you will rev at the same rpm as you normally would (assuming you are buying a stall with lockup capabilities, which you should...

Hey...I'm lurking round here to :p ... I'm actually attached to a triple throttle body manifold I think I saw on here awhile back...I think that would distribute the airflow a little nicer to the cylinders, the only thing that has me worrying is the turbulence of the airflow in that tiny...

1/4 mile....12.3 to be exact...and on stock heads lol...you just need the right kinda combo. Actually I expect at a minimum a high 12 out of my car as last season on a smaller cam and only about 15-17* of timing (due to KR) I ran 13.6 when I spun a bearing in the motor. My old cam was 210/220...

no one is staying N/A over here?? anyone running any custom inlet manifolds? I know I've seen several posted, but I want to know about the ones specifically on cars and the types of gains you got and with what kind of mods? More specificically I guess the VS style motors?

as long as you are going to stay N/A 4.11's are fine than...if you go F/I that gear will be too short

I dunno if your tranny gears are like ours, or which tranny you guys have...but if it is like ours I'll say go 3.90s...I originally had 3.90s in my car and loved them...after blowing 2 rears and putting in a ford 8.8 I didnt have a 3.90 option so I jumped up to 4.11's...I did notice a difference...

I dunno, I've always just felt that FI is the easy way out and that N/A power gains are more of an accomplishment to be proud of I guess. We have a couple of guys In the USA that have run low low 12's N/A..I myself am expecting to run high 12's as I sit currently, but I would ultimately like to...

I've been searching for info on your motors...I got the buick 3800. I'd like to see what are your notable all motor builds you guys have going on? Anyone running 12 seconds or better all motor? What was done? I got an Aussie Lower intake manifold myself kicking around, I was toying with...

New over here from Canada. I don't normally do an introduction thread, so excuse me if this sucks lol. Don't have a commodore either, but I got your american 3800 counterpart with an ecotec holden intake manifold waiting to go on. I joined up mainly because I am looking for information and...
