As i'm sure you all read in the other thread, i've lunched the turbo on my RB20 on the way to work today...

It was the compressor blades that broke (not exhaust like normal) and there is fine metallic dust through the intake, and it appears to be on the tops of the pistons as well... Now, i found larger chunks of metal through the intake, i just don't know if any of those made it into the engine....

Now, the choices i have are:

Put another turbo on and hope for the best

Buy a wreckers engine and hope for the best

Get my current engine rebuilt

Now, there are pros and cons of each.....

Pros for putting another turbo on....

Cheapest option

Cons for putting another turbo on....

Could spend money/time putting it on only to find the engine is fubar, and be in exactly the same situation

Pros for buying a wreckers engine....

'relatively' cheap option

Cons for buying a wreckers engine....

don't know past history, it could have been thrashed, on the verge of death etc... could only last a month or 2 before it dies and then i'm back in exactly the same situation

Pros for rebuilding the engine....

Will be a brand new engine, you know exactly whats done to it, how its been treated, should last for years and years to come (i'm looking to keep the car for a fair while hopefully, as it owes me too much money to sell), the engine has 190000km on it anyway, so its just about due for a rebuild...

Cons for rebuilding the engine....

Is the most expensive option

What would you do in this situation?

Keep in mind that i need the car for work, but i could probably get away without it for a week or 2....

I should have mentioned.. if i got it rebuilt, it would just be a stock rebuild, with possibly some forged pistons (because they may even be cheaper than standard nissan pistons)

I'm only going to be chasing ~200rwkw from the car, so don't have to go overboard with the engine...

im gonna say go with a second hand engine, and get a warranty on it, if something stuffs up, warranty, ask them to test the engine before you buy it even, get a compression test etc, if you have found shrapnal in ypur engine...you could also get a rebuild, but it all depends on how much value a rebuild is going to give you...and the cost when you work out how much damage you have done to your engine.

A. if you got a rebuild you will know the internals, but it will more than likely cost more than expected (past experiences) also, you will rebuild it and then still have to get either the turbo fixed or get another turbo.

B. if you got another engine, that was possibly tested, for less than the rebuild, worst case scenario, something dies, but you now have enough parts to make one engine from two, best case scenario, compressions are all equal and the car powers on like it should and makes your 200kw :P a new engine might come with a turbo also, ruling out some more cost...

C. you whack another turbo on, and the engine screws up, first off you needed the turbo anyway as the other one is stuffed, secondly you need to then choose either rebuild or get another motor so you are in the same situation as before but you have ruled out one possibility. only problem i can see with that is that if the turbo gets damaged in the process of driving the car if something is damaged or some crap gets in the oil. other hand, if the engine works fine, then you have saved yourself the cost of a rebuild.

lol. ok i'll stop rambling now :P good luck

how long you wanna wait? my rb20 is coming out in about 2 months.. never mucked with until I got to it.. Still pulls pretty hard and you can check the compression, etc in the car.

Mine will be cheaper than a wrecker engine.. probably about $900

Otherwise, just get an rb25 or better.. it will add to the resale value of your car amongst 50 other R32 out there. Rb20's aren't the greatest things.

well, i got quotes today for rebuilds etc... most places want 5 - 6k for just a standard rebuild! ouch!

However, was speaking to 101 Motorcafe, and they said they can do a RB25 conversion for me with a low-kay RB25 for around 4 - 4.5k drive in/drive out....

Now, i said to them what sort of things can we check to make sure its not going to grenade itself within a few months etc, and they said that they could do a compression/leakdown test, pull the head off and check that everything looks okay, and also pull the sump off and make sure the bearings etc are okay.... any other suggestions?

101 is pretty good too. I havnt heard a bad thing about them yet. For what you use the car for dude, the 25 would be probably the goer.

    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
