hello mona

Sorry to hear about you motor.

I got some parts laying around at my shop if you need something. Standard cranks,rods,ETC.

As for the engine, I wouldnt really blame the Tuner.Sounds & looks more to an oil surge which could of been a long thing comming.

As for this rev limit business,I sit on the limiter which is 8200RPM doing my burnouts with the standard motor on 18 psi.As doughboy and buster have seen.I wouldnt blame hitting the rev limiter.

What is you rev limit set on mona and do you have an oil Pressure guage in the car.What oil do you use in your car.

my opinion on the cause is either

-Rod gave up

-Oil surge

For this to be caused by pinging the pistons would of all been rounded on the edges due to detention.

Good luck with your new build.I would stick to the RB25.RB26 if you want to spend the money. I wouldnt recommend going to the RB30 stage till you wanna run in the 9`s.

I don't think i ever blamed the tuner?! but i did say my car has a very long history of pinging... i NEVER had a ping free tune!! on the road.. most times... on wsid... i always saw the check engine light flash and would fix by chucking in octane booster!

rev limiter is set to about 7.5k i think... and i VERY RARELY hit it! even at ec! i did hit it once or twice when i was still learning where it was.. but thats all... and on the track... i don't think i hit the limiter at all!!! there isn't even enough room to!

it was an oil surge and not detonation like i previously thought.. but it does look like (as adrian has stated) that there was some detonation... and my mechanic did see alot of damage due to detonation in the engine... it may very well have been a combo of both!

no oil pressure gauge and i use motul!

thanks for the offer for parts... i'll keep that in mind! :)

yess. oil surge is the suck. hope all are learning from this debarkle

and there was no evidence of detination on any of the good pistons. so chances are you propbably had a dicky knock sensor..or they were done up to tight on the block

ie.. track use you MUST add at least an extra 1-1.5 litres of oil. but any way...back the the great debate.........:

for all intents and purposes a 3litre would be the go. i have given this much thought.

from having a 330rwkw dr30 i know traction will be very limited on the street.

so either way a 3litre or 2.5 doesnt really mater. from a budget and down time point of view id do a 2.5.

but for the wow factor and ultimatly the better setup for the street id go 3litre.

besides. why rev it past 7k anyway. i know mona doesnt like lag so chances are itle have a relativly small turbo.

clearly the combo works whether it be with a 26 head or 25 head. so you have my support either way

cool. a anti 3litre argument. :)

Not really just misinformed parrot quoting information and being corrected, I too get sick of all the go RB30 talk as its not always the best or easiest solution as I keep saying each RB has a place if only we could all get over our oooh RBXX is the best attitudes and keep open minds :P

hahaha... nah.. thanks morgs :D

i really am still deciding! its alot of money to consider! my mechanic is putting together a pricelist with possibilities.. it really comes down to what i'm willing to spend... and depending on my mood down the track it can range from alot to very little...

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
