Hey Guys,

My GTS-4 needs a new timing belt aswell... only 55,000kms on the clock so i kinda smell a rat too.

I also have been told i need a water pump aswell so thats handy to both at once.

One Question... How much effect would a stuffed timing belt and water pump have on the performance of my car?  

Thanks

your car wont run without a timing belt dude, might run/idel rough with a really worn belt. But its either on or off. Check your belt for gashes/splits and replace if need be.

if you water pump if fuged, your motor is going to run real hot! as water isnt circulating through your radiator & motor. If you cook your motor, your also fuged. Depending how bad you cook it, you could be up for a new motor. (as the motor+ head expandes under pressure, and never returns to orginal state. Leaving your head/motor warped in some areas. This will mean that water is going to get into your oil, diffrent compression readings accross all 6 cylinders. etc.)

Guys,

just for a bit of genral info about the timing belt:

Timing belt controls both camshafts in the RB20,25,26,30

camshafts control valves & valve timing inside the combustion chamber. Valves control the amount of fuel + air entering and exiting the combustion chamber. if the timing belt snaps, the cams & valves stop turning & lifting, but the crank still spins a short time after. This is wear the damage occurs. Ignition is still active, injectors are still fireing fuel into "stuck open valves" & closed valves. This all will stop in a few seconds after the belt breakes. You might be able to buy a new belt, and start it straight away without any problems. Or you may be up for a new head, set of valves, or a couple of pistons. Its just luck! :)

hope this helps.

I think that if they just had to replace a timing belt you got ripped off! ( but then again it is a alfa!) & i dont know how hard they are too change on the alfas!

But if you motor sustained any damage due to the belt and the head had to come off... that price sounds pretty standard.

Cheers,

Trev

Timing is timing dude!

all happens in 1/10th of second. Wether its a nissan, dihatsu, or alfa! :P

just make sure you belts ok, and make it a genral rule of thumb when you service your car. (i service my car... as i dont like the idear of 15Y/O, year 9 drop outs, apprenticese's, servicing my car! and i also dont like the idear of the shitty generic oils and belts that nissan use & not to mention my biggest fear........whos car they choose to get the lunches!)

Just a quick tip for the people who are extreamly paranoid, take a photo (with the date printed on the photo) of you odometer. They shouldnt move the car more than 100M...... if they do... ask why? and ask for a complete service report. I have many freinds who work at these places and dont feel completley secure about having a "geniune" nissan or holden service. They all hire apprentices.

    • Then today, I went to visit a man with an r33 hat Peter and Road and Race sorted the alignment. As it is being set up for general track/hillclimbs etc it has a heap of caster (7o), less camber than I am used to (1o front and 2o rear, as the caster looks after that in turns without the braking downsides), 3mm front toe out and 0 toe rear. Will see how that goes and track tyre wear to see if it does need more camber, but adjsustment is also limited with nismo arms and adjustable bushes at only 1 end. It does have a bent inner tie rod on the driver's side front but as it came up within spec I'll just leave that as is. So, that is getting close to my chapter of this story....could of tidy ups then a shakedown in early October before it finds a new home.
    • So, it went to Unigroup for a run in and tune on Friday, everything went (generally) well. In terms of fixes, the engine was good and there were no leaks. It needed plugs (I hadn't checked them because the coil pack cover was on a new engine and I couldn't imagine they weren't new.....but turns out the temporary plugs to just keep it sealed up were in there.....new plugs gapped to 0.8 and it was fine from there. Also, there was a little preload on the clutch slave which caused some slip. I haven't had the box off so I don't know what the clutch looks like; my guess it is brand new and the pedal had not been adjusted....backed that off a bit and it held fine. Last thing will have Dose crying....the idle especially when cold is a bit difficult between the cams, forward plenum, atmo blow off valve and an 80s air management system. It is fine when hot but a little uneven when cold, will see if I can sort or at least improve that one cold morning. Other than that, tuning went fine. It made 245 but was pulled back to 227 which 2 opportunities to improve in future. 1. The factory CAS is not great and was jumping around at high RPM, so Mark took 2 degrees out up top (that is why it stops making power and lost 20kw). Very safe this way and the extra power is available but will require a more modern ECU and better cam (or even better crank) sensor 2. The 2871 in factory housings is very big for a low mount, and the internal wastegate is too small, so it was creeping from mid range all the way to redline....the duty cycle on the boost controller is turned down a little for safety. That is much harder to fix, it would need a large external gate and that would require a whole bunch of other changes, so it will go as it is for now. It feels nice and healthy and safe, so should be good for about a billion laps like this.
    • what sort of caliper are they? If they are a slider and you gave everything a good clean, you might need to regrease the pins. My guess though is they will come good after some abuse as suggested above
