got a few prices on some things, what do you guys think?

Rb30 water pump (silverline) - $80

timing belt (dayco) - $22.95

Rb20 thermostat and housing - $28.95

Rb30 sump gasket $12.50

Just wondering is the brand 'silverline' a good brand of water pump or should i try and source a genuine nissan water pump?

all good :(

Make a choice on what thermostat u want, -genuine std .or aftermarket. They differ slightly in the way each holds water temps.

what would u recommend?

What about the water pump? genuine nissan or won't it really matter?

i have used both aftermarket and genuine thermostats and would recommend the genuine nissan.

i have also used various water pumps, i currently have powermax on my car which is fine.

why the genuine nissan over the other brands?

my car ran considerably hotter with an aftermarket than with a genuine nissan. The aftermarket also got stuck open after a while, i changed it back to genuine nissan and havent had a problem with overheating since. I also use the standard clutch fan although people are starting to change to the twin AU thermo's which work well.

well i just rang another nissan dealership here in adelaide and they only want $260 for the vrs kit so search me? I also asked them about the thermostat and housing and they've said about $110 for both compared to the $30 i got quoted for the non genuine nissan items, do u guys/gals really think its worth spending the extra $80?

I like the genuine thermostats. $~50.

They get the car up to operating temp real quick, which equals better fuel economy and less engine wear.

From my observations the aftermarket thermostats react very quickly, in other words it flings right open, and very wide, and shuts really quick.

The genuine tends open not as wide and it does so a little slower, it also closes slowly. If that makes sense.

My sister had overheating issues in her VL Commodore when cruising up Willunga Hill (big arsed many km hill), drop the genuine thermostat in it and its fine.

I suspect the aftermarkets open too much that causes issues with either water flowing too quick or some some how reducing the pumps ability to flow?!?! No idea.. ;)

Grab a decent quality RB30E waterpump that come with a gasket, no need for rb26 n1 items unless it will see lots of the track.

As far as I'm aware there is only a genuine thermostat housing available. Obviously, they are a little pricey. :)

Use the one of your rb20, it should be fine.

Don't forget to change the block heater hose attachments on the rb30 to suit the rb20 setup.

One off the thermostat housing and another at the rear of the block on the drivers side.

so get a genuine 'Nissan' one form a nissan dealership? water pump that is!

I think they're about twice as much as getting one from motormate/sprints?

ok, i found an rb30e waterpump, Brand name 'silverline' sounded pretty good for $80 and came with a warranty. I'll keep my thermostat housing from the rb20 as it looks in pretty good nick and i'll just grab a genuine nissan thermostat, better to be safe than sorry!

What turbo are you bolting on the 3ltr rbman?

Stocker for a while or..?

With these petrol prices i'm starting to want some lag back.. :P

The 3ltr drops out of closed loop mode so easily, its actually quite hard to accelerate up to speed and keep it in closed loop.

The old rb20 would stay in closed loop until it was making a psi or two.

RB30 being the rb30 spools 1psi as you let the clutch out at idle. :)

Bolting a XR6turbo is looking attractive. Even if it doesn't get going until 3800rpm or so who cares. ;)

I find I don't really use the power under ~3500rpm.

Is that the way you'll go Cubes and yes mileage is important to me as well , hence pedalling on loan G11 Charade - true king of three cylinder carby n points terrors !

I can well understand why JE had heaps of fun in the turbo Mira .

Beware of the flying flea cheers A .

I'm able to get the bb VG30 pretty cheap so thats what i'm looking at pretty much before it gets bolted into the car. I remember you saying with your pissy little turbo that u were getting crappy mileage so i figure if i spend a little on a bigger turbo i'll save while running the car in and waiting for my 35/40 :D

Another noob question, Do you use the rb20/rb25 runners and plenum? I just can't remember what you said a while back!

Fuel economy isn't too bad, roughly 430kays to 50litres or so.

I am finding it annoying how she snaps on so hard with such little acceleration, you constantly have to be on the ball when trying to accelerate just that little bit harder than limping pace.

The VG30 with its larger turbine housing will be better suited and smoother to drive.

------

Use the R32 RB25DE inlet manifold and RB20DET plenum.

You can use the R32 RB25DE plenum, it lacks the BOV's boost feed, T into the carbon canistors feed.

You will also notice the turbo inlet manifold has a water galley run around the injectors that then feeds in to the turbo water lines around the back of the head. On the n/a inlet manifold this is blocked off. Not too much of a drama, I left mine blocked off. :)

I drove my oldies 100series v8 landcruiser around for a few days this week.

Jumping back in to my car I realised i have a big diff whine. :D

What clutch are you settling on?

    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
