I'm looking at the costs invovled in an RB26DETT engine re-build. The current engine runs fine, but an update wouldn't be a bad thing.

Not including labour, what should i be budgeting for? .....Pistons? Rings? Bearings? Rods? Cams? Water pump?

Where possible I would like to use genuine parts or better for similar cost. Can anyone help with ball part figures?

It's a bit hard to give you a ball park figure if you dont want labour costs included. They are the killer......

I was speaking to two well known reputable people today and the general rule is to budget for about 8k drive in and drive out. Depends on spec but yeah. It's around there.

That all sounds reasonable. My thought was to try and buy some of the parts before, as you say Gav, spread the pain!

So I should be looking at buying pistons, rods, metal head gasket, anything else or major concern?

is replacing the cams and upgrading the water pump a good idea?

I've bought some N1 turbos and will put an oil cooler on it. i will also freshen up the radiator core.

Arias forged pistons ( rings +pins included)=1200 ,nissan about $1000, bearings aftermarket $200-250 for both mains +big ends , nissan add 100 , nissan water pump $150 , oil pump $500 ( nissan ) Don't know about rods ( i wouldn't change change them if o.k. unless you want over 600 h.p.) , nissan full gasket set $300-350 and you may need a couple of seals ( don't come with set ), aftermarket cams depending on what you want $900 + for the 2 ,then you have servicing the cil head , reboring the block , grinding the crank and allow a couple hundred for belts and what ever and thats about it .

Ah and while you have the donk out you may as well do a clutch and while the box is out the synchros and a while the box is stripped repace a few bearings in it or any worn gears .

Synchros + box bearings are cheap labour will not be .

N1 turbos are just right on rb26 ( depending on which n1's you have )

I have them in my r33 and they are fantastic , good response and making over 300 kw @ the wheels with only power f/c , full exhaust and 1.2 bar boost .

you sholdn't need a metal head gasket as the standard nissan unit is quite happy to service 750 hp.

Same with the water pump...as if

And a couple of hundred for belts and whatever else is not enough.

Should always alow 500 for the extra stuff like heater hoses (which you must change if you haven't already)

Genuine R32 GTR water pump is $300+ from Nissan (trade).....I'd like to know where you can get one for $150.

Get the R33 pump. Only two days ago I was quoted $485 for a "genuine R32 R" water pump. I picked an R33 GTR one up brand new the next day for $170.

They have different part numbers but they do fit....

Thanks for the info, I assume the $170 price was over the counter at a Nissan dealer ?? Do you have the PN ??

Must be some difference other than the PN. Interestingly UAS have the genuine N1 water pump also cheaper for the R33 GTR compared with R32

The part number for the N1 water pump for the R33 GTR is 21010-24U27.

I bought mine from Unique in Sydney and it was $195 including delivery to Victoria. I believe they have gone up in price since.

AFAIK, they need to be modified to fit the R32 which is the reason for the price difference.

wrxhoon  - Thats just the kind stuff i wanted to know! Aiming for 300kws with minmal stress on components. Yeah, while its apart I figure do the gearbox and clutch too.  

Thanks.

Sorry mate i didn't realise you had r32 gtr , the water pump price was for 33 not sure if you can fit to early rb26 ,they look the same to me ask around .

The prices i told you are from nissan hornsby ( sydney ) or lintof motors ( sydney ) sometimes one is cheaper than the other and of course they are trade prices .

Aftermarket parts , for pistons and bearings try Rocket industries ( sydney ) but again they are trade prices . I'm sure there is some nissan dealers in melbourne and aftermarket parts shops but i live in Sydney so dont know where .

I dont know how much work you do yourself if any . Removing the gearbox when you have the engine out , if you get it done somewhere, shouldn't cost you any extra , i always remove engine + g/box togeter , its easier .

As for rebuilding the box , of course you dont have to if you want to put up with worn synchros , its not going to bust it will keep crunching on quick gearchanges though .

Clutch is a must if you going to put extra power though , i only use a full face single in mine ( its a much heavier pressure plate than stock though ) and it holds very well . I have run 11.7 @ wsid at 121 mph , the car only has n1 turbos ( i rebuild them before puting them on ) , power f/c , ebc @ 1.2 bar and full 3"exhaust , everything else is stock including stock airbox .

The power you want you dont need to change rods or even forged pistons for that matter ( but they are almost the same price ) .

You can get wiseco forgies for under $1 k but i dont like them , ask others that have used them they maybe ok .

Allow $10 000, you will need it.

Trade price for the genuine R33 GTR water pump is $120+change (just got that price from my local Nissan parts guy in the last hour). That's a BIG difference compared with $300 for the R32 type.

I'd REALLY like to know what the differences are between the R32 and R33 GTR pumps......think I'll start another thread.

I was told they were same same. But even so, if they needed to be "modified" to fit, I'm sure it would be minimal.

They look the same...

But yeah, how is the price difference eh? :confused:

Better start that thread though just to be 100% sure. I will find out on Monday if my 33 R pump will fit. I'll keep you posted :D

Correct prices have gone up a lot on N1 water pumps. There is a difference in 32 and 33 we mod the R33 N1 to suit R32. There is no N1 pump for R32 and the R32 water pump cost a lot more.

    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
    • To drain the Intake Heat Exchanger, there is a crappy drain plug in front of the driver's side front tyre: You should use the largest headed phillips screwdriver you had, and in my case I needed vice grips on the hose above as the plug was tight (tighter than it needed to be, since it has an o-ring seal).  After you have a tray down and open the drain, open the intake heat exchanger reservoir cap (drivers side one) and you should get a couple of litres of coolant To get to the radiator, you need to remove the plastic engine undertray. It is held on with a series of 10mm headed bolts and some clips. For the radiator, there is another type of crappy drain (kind of like a plastic banjo bolt) and you should attach a length of hose to direct the stream of coolant per this pic (otherwise the coolant hits the rad support and goes everywhere). The drain is on the rear of the radiator on the driver's side and a bit hard to find. Put a big tray or bucket down (5l won't be enough) and slowly unscrew the fitting by hand. You only want to remove it far enough for coolant to flow, it you unscrew it right out the whole fitting and direction pipe will come off and you will get a coolant bath (yum!). Undo the radiator reservoir cap and it should empty about 8l
    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You also need to drain the intake heat exchanger to remove the radiator so you will need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. 2 other tools that really help dealing with coolant lines and spring clamps are Bent Needle Nose pliers Hose pliers Between them they will reduce the frustration (and injury) potential by about 1000% Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
