    Water hoses/Water pump help

    For a short time I fixed water leaking out of most hose connections ( when the engine turns off ) with a new. 1.1 bar radiator cap, then burst a couple of pipes but now some leaks are back. The latest leak happened after changing gear to 1st gear at 55kph and accelerating up a slight hill at...

    The WALL ( no more acceleration )

    Just curious when people stop accelerating in over drive on a steepish grade say 17% rise. I notice I hit the wall just after 120kph 74.5mph at 5 psi curious thing is about this right for the torque I have at around 3000rpm in OD and my car mass of around 930KG+driver. It needed 15psi on the...

    Exhaust Back pressure and oil leaks

    Looking to fix the 4e leaking seals but repairer says they will leak again. I am wondering can pressure through valves seals get into the block and push out the block seals? Seal Symptoms are - Exhaust back pressure seems to be the cause of oil squirting out of the top breather...

    Temp gauge at bottom with FMIC

    Not usually this cold but today was 11degC and while cruising at 110kph I noticed the temp gauge went fully down. Is this the usually thing with FMIC and colder weather?

    Air temp sensor ( racing type ) too much variation at idle leaning when very hot.

    From what I have read the air temp sensors can override all other sensors which is what I seem to be experiencing. As you know NA has air temp on air box where as Turbo has it in the inlet manifold after the throttle plate. I think the idle heat from the pcv plus heat in manifold and hot bay...

    Auto box shudder - now gone

    Auto box shudder - now gone at low boost I had shudder going from 3rd to OD on the auto box and that got really bad when accelerating hard at the change point. Simple fix - I changed the gear box oil and the shudder has gone. [ Yes old tran. oil - it felt pretty flat between the fingers it...

    Rod weights for 4efte piston

    Does anyone have the stock 4efte or 5efte rod and pin weights? I have seen a post saying 4efte EP91 Con Rod is 11g lighter than EP82 and so are the pins but no actual weights were given. I was wondering how much lighter the stock rods would be than forged rods that are 420 grams.

    Knock fun with safcII

    I am gradually warming to the idea of the SAFCII knock function. The manual says it picks up some but not all dangerous knock. That being said I am finding it is pretty capable and thought I would share this experience from when my car was running lean ( approx 16.33afr at 2800 ) and I had...

    ct9b does anyone know the 9 blade exhaust wheel size or exhaust port size?

    Threads seem indicate the ct9b exhaust side blades are the same diameter as the ct9a exhaust blades ? I am looking for some size confirmation on this as the ct9s I have found on the net dont seem to match. I particular the exhaust port size or the smaller part of the blade diameter the...

    Knock noise at idle

    I have noticed a lot of ' tinny ' high frequency sound coming from the top of the engine at idle is this knock ? I show a lot of knock below 950 rpm when engine is rough but knock is gone by 1300rpm on safc2 when I rev the engine. I have been ignoring this but could do with some ideas...

    Earthing the intake manifold even though it looks properly earthed

    I have been tracking idle issues for years improving gradually including removing aluminium oxide ( white powder ) discovered on the intake manifold earth bolt thread. Cleaning the bolt thread made an improvement but after a short time even with the bolt sealed very tight the poor idle and...

    Management light on or is my car trying to tell me something

    Well today I had 2 lights on never had that before . I changed back a gear and boost shot up to 15psi but I noticed I had left the ac idle up on ( which reduces my boost gauge reading by about 4psi because it shares the same vacuum pipe.) this means I had about 19 psi or something around there...

    o2 sensor limits and open loop

    o2 nb sensor limits and open loop I read that some ecus go to open loop when the o2 sensor reaches its reliable limits. Now as many will know typically narrow band o2 is accurate from 14 afr to 15.2 afr outside this perculiar things happen, variations on too rich and too lean also temp...

    Timing advance stock ecu

    Well trying to check static timing today noticed a few things. Looks like I am running about 9.5 deg of advance which is ok as I boost spike well above 18 psi and run a safc2 which is supposed to advance the map a little. > when I took more fuel out at idle with the safc timing was pulled by...
