Im doing the vt hub and rotor swap on my VH and my right side has rust in it. Q: do I have to replace the whole strut or is the axle removable somehow? I dont think I can sand and polish the arm, can I?

What were your mods if you dont mind me asking. What was the end result?

Just read his web page. Sounds promising. Thanks for that.

Who do I contact for a delco tune for the Holden 304. I have read Greenfoam used to with great success. Im doing my rebuild on a budget and could do with saving a heap of cash to put on something else. Its pretty much a mild build that shouldnt need parameters changed a whole lot.

Theres also the remote mount turbo option. Placed at the tail end, ive seen a few cars with the mod who have had great results. Bolt a 2L oil tank in the boot and an electric pump to feed the turbo. Add a cooler and fan if temps get high. But a Garrett 35/82 on a stockish block would be plenty...

Nice, how would I find if the ecotech sensor will give the same reading as the stock? I mean is the signal output the same.

Ive modified my bunch of bananas manifold to take a 90mm throttle body. The Idle air control is sorted but my throttle rotates clock wise whereas the standard was anticlock. I need a Throttle position sensor that rotates the same. Question: What parameters does the sensor have to be or can any...

Im replacing the cam for a performance cam probably crow 4503. I pulled the old out and noticed it is a Crane. As far as I know the motor hasnt been rebuilt. It has 950800 stamped in the bottom but this code doesn't match anything in their catalogue. Is it from factory? Is it custom? I...

Don't know the cam code but call them and they can fill you in on designs. Like EYY said, id go turbo for price and simplicity. Twin screw blowers are cool as f, but not easy to engineer. With a typical Garrett 35/82R you can make 300kw and boost will come on early and steadily enough. But if...

I was contemplating the same but with Eaton m112. For 300kw around 10psi running e85 considering its a weekender. Crow make a boosted cam profile for the 304 for a twin screw. The beauty of twin screw as opposed to turbo or centrifugal is you dont need high revs to make power. You could leave...

I may fall short but pretty sure I wont be far off. Mates with similar mods without touching the manifold saw 180-185rwkw. If all else fails ill install a sneaky pete 50hp NOS.

Dont port them on a mild street car. Unless you're stroking with hi comp and want to have it rev high. The restrictions from everything else will waste the efforts of having the heads done. $800 could be much better spent.

The biggest restrictor in the 5L is the manifold. The throttle body to be precise. The intake has 8X 40mm runners bottle necked by a 90° bend and a 65mm t/b. If I were you I'd bolt on a set of extractors and twin 2.5"- single 3" mandrel exhaust. Im aiming to do the same thing on the cheap...

Does anyone know why there are coolant ports at the back of vn heads but the manifold doesnt flow coolant through like at the front? Also I wont be welding, alloy is beyond me. Im getting one of the boiler makers from work to help out. Do you think there'd be enough heat to warp the manifold...

So I decided to cut the bottom off to port and hone the intake runners by hand. Extrude honing was too expensive. I think I can get similar flows. I also noticed at the back of the heads there are coolant ports that are blocked by the manifold gaskets but the manifold has bowls to match the...

Fibre glass is much easier to make than alloy. I wouldnt know how to make a smooth alloy neck. I have to maintain a certain angle as the thermostat housing blocks a clear access for straight on. I could make the neck straight to the TB and have an angled 45° hose. How expensive is extrude...

So far I have cut the neck off. I will be welding an adapter plate and bolting a hand made fibre glass 90°neck mated to a 90mm tb. I am thinking of placing a divider plate through the neck to split air to each bank. Upon cutting the neck I noticed the runners at the plenum are rough some have...

I have a VH, 304, VS brake booster, VT master cylinder. It has vl turbo brakes/rotors. I want reliable stopping power to handle a 300+rwkw turbo 304 and take it occasional racing. K mac sell a 356, 8 pot for $2300. Id rather do it once and do it right. What are your suggestions? Anything I can...

Orange wire wasn't connected. In the engine bay there are relays for fuel and injector. With a test light both get power and fuel fuse lights up when priming. I relocated the ignition module but its still plugged in. Is there a way to find if its ignition?

Hi guys. i have an EFI 5L powered vh. Recently i took it off the road to fix/clean and upgrade it. I have a hidden prime switch and dash push button start. Upon trying to start it the fuel primes and push button engine turns over but no life. I cut out the Python alarm/ imobilizer and...

The car used to run. The alarm/imobilizer was a python. I had a spark plug pulled out but it didn't have a spark jump across it. Sent from my GT-I9100 using Tapatalk 2

Hi guys. Im struggling to restart my project. Its a Vh Sle with a EFI 5L. I've redone the interior and changed a lot of the dials, switches and buttons. I have an ignition switch and push start button. The fuel pump primes and engine turns over but no spark. I moved the ignition module while...

Size of turbo depends on the power level you want to reach and what the car will be used for. For a daily driver id choose a Garret 35/40. It will spool quick and make great boost over a wide range. to change to turbo you need to run headers to single merge and plumb into the turbo behind...

I use Penrite 15/60 semi synthetic. While im on i thought id ask if there was someone with a world of knowledge on oil that knows of a better choice. I use the standard oil pump and know pressure is low so is there changes to be made? Also, are there additives that have a positive effect.

Green foam, amazing thread. Could you please inform us less knowledgable people of how the different cam specs ie: lobe height, seperation, duration etc, affect/work with different car mods eg: Exhaust, intake, fuel, compression, diff gears, porting, timing etc. As every performance mod...

$15k you could stroke, blow and trans with >300rwkw. more if you do work yourself and save money. not to sound soft or boring but 600rwhp (455rwkw) is huge power. you could light up the rears at 100kmh. maybe go in steps. 1: stroke with boosted friendly comp (<9:1) = <$5k and 250rwkw 2: boost...

if you want substantial increases id say stroke, forced induction, nitrous (not street legal) otherwise simple mods with limited gains would be a CAI, extractor/exhaust heat wrap, tune to run E85 or electric water pump and fan. you could go bigger valves with bigger ports and large cam and...

im having problems working out the wiring on my msd. what i cant work out is to use the white wire (amp output) or green/purple (mag pickup). on my wiring diagram the ignition module has three wires connected to the dizzy and one to the coil which also relays to the tacho. is it the wire to the...

i have the same problem. i have my battery in the boot so all the wiring is close together. where would be the best place to place an earth in the back of the car.

i have a problem where my 304 motor doesnt like idling when i pull up at the lights and often stalls. it idles fine, has plenty of power but wont find 600rpm to sit on after ive driven to a halt. ive been told the TPS may be playing up? im guessing its either that or the idle control. is there...
