Also, I'd take 20 year old nissan manufacturing over most builds any day... Al has had to have his built 3 times now aswell, as has Dean.

Yes, this is the power of a decade of hindsight and knowledge of what happens to others, a much larger sample size than 1. In theory, a proper rebuild should be fine.

There's also the argument of how long or what better durability you actually get from a rebuilt 350RWKW engine. I don't think any amount of forged parts or expert assembly can get you 300,000kms at 350RWKW, it doesn't seem like that would be a reasonable expectation anyway.

Or what would happen if you got a forged build and then only drove it like a regular road car, then saw how it looked/lasted 300,000kms. There's not really enough data for it.

Race cars build race engines and they make 500hp or what have you, and they last four laps on a track every now and then. Whats that, 15kms per rebuild? Expecting a 2.5L to make 200,000 track kms just because FORGED is a bit much.

Still would be nice to last more than 500kms of street driving. ;)

Mine still going well 45,000km at a half decent power level daily, just do my oil every 10,000 and clean air filter

tl;dr get a v8 m8

A pretty valid point actually. There is a lot of merit putting a LS1-3-flavour into a RB, S13, whatever if your goal is 270-300rwkw.

Response, Sound aside (both benefits for a V8) there's merit in it being legal, EPA wise and the main factor of it working near 100% of factory/designed power, vs trying to run something at 200% of factory power.

v8 m8 is gr8

?

are you trying to say it's legal?

It's entirely legal to V8 into things, if you do it correctly, which can be done.

I know people who have engineered RB25's into things as well, but if your aim is hiflow RB25 territory for power, why not V8?

There really isn't any reason not to.

cost of getting a 5.7l motor engineered into a factory 2.5 = not worth it

Did you say this 8 years ago?

The only reason I've persisted is because I got the Stroker kit for near nothing and had a free rebuild coming my way via someone who had a really, really great reputation 8 years ago. Someone who was recommended directly by someone else who owns a certain hub dyno, at the time.

I did initially put a stock neo in, it just got exploded before I took delivery of it, my options were

1) Free replacement neo, which could have the same problem.. or..

2) Near-nothing RB28 upgrade which would have 0kms on it, which you'd think logically would be better option long term.

Again, this was 2007. We all have 8 years of experience since then to see what works longer term and what doesn't seem to. I would still say, that if the engine was implemented correctly that option 2) should still be the better option to go down.

Even if you still only want 320rwkw, it's a better option to have a new engine over an old engine, assuming they are assembled to the same standard, which you would think would happen in most/all professional scenarios.

You'd think.

And you were trying to convince me to go a neo

Well I think this is your problem Greg

Also you don't know when to call it a day on something, like I admire the persistence, but sometimes for your own sanity and wallet you gotta move on cause no amount of solution or success will make up for the journey you've had to take and continue to take to get there

Shit is sucking you in like a succubus

I advise all people out there to simply go to where a hiflow will get you on a RB25 (i.e 320ish) because its the point of which everything else breaks or becomes very visible to Mr Plod.[/img]

People take your advice on modifying cars?

Everyone bagging RE, meanwhile my old engine is still going strong

I agree, but every now and then you see them pop up/appear with something already in it. Someone was selling a S13 with a LS2 in it for 6k before, with the gearbox and engine mounted. Someone with some know-how could easily pick that up and get it finished and enjoy it for quite a long time. I would rather a LS1-LS3 than say, a RB25 into a 180sx was my point to be made.

Big difference than say... putting a LS1 into a Supra because "its better to run an engine at 100% than 200%"..

I wasn't suggesting the neo for you, I was thinking about it for me. :P

There is no reason to call it a day on something, because there is no actual demon involved.

If I gave it up and started again, I would want/get something very similar to what I actually have.

If you sold your GTST and started again (Ignoring the GTR) you would get... another GTST. With the same mods, with the same problems and things to consider. I'm not actually trying to push the envelope or do anything too unusual. I just want what is relatively standard to actually work correctly.

I would never recommend anyone put a neo into a 33 because the benefits don't really make a lot of sense given how hard it is, for some very minor benefits if any at all.

son of rajab knows I know what not to do, and what to look out for by now :P

RE had a good reputation for a reason, for awhile.

new worst thread on SAU: http://www.sau.com.au/forums/topic/460737-z-tune-inspired-r34-project/

R34 GTR with 15 pages in 2 weeks of endless questions and indecisiveness.

made worse with the countless threads with the OP asking about purchasing a R34GTR

    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
