here it goes --A water jacket was leakin on my engine and didnt notice after 2 days! So apperently drove the car with little or no water to and from work 15mins each trip for 2 days! And the temp gauge read normal.

So i changed the jacket filled her up and ive been using her for 2 days now and noticed today when i came from work the catch can was filled to the brim with oil.

water Temp reads fine

oil pressure reads fine

wideband reads fine

car still makes power like before

What u guys think? Seems like i would forkin out for a rebuild!?

motor is f*ked lol

when i cracked 4 pistons in mine, car still went hard, idle like a VW lol and i could fill the catch can pretty quick.

rebuild time mmm

doesn't sound promising, i hate the factory temp sensor cant trust it one bit

in s13's the temp will only go past the middle when its 100c...fail

i know this may be a stupid ques but should i drive it? seeing that it fills the catch can with oil on a 15min drive

Also wats fu*ked Ringlands?

well it was 4 cracked ring lands on my pistons that went.

personally i wouldn't drive it. park the car leave it and work out your budget then send it somewhere to be rebuilt.

Step 1/ Take car to mechanic

Step 2/ Have mechanic perform compression test

Step 3/ Go from there

better solution:

go to supersweet auto and get a $25 compression tester

do compression test (the tester will have instructions but i can explain if needed)

should be getting anywhere from 140 upwards in each cylinder

Dr Mr Smell.

I hope you dont take this the wrong way, but i have done some looking around and I have found out why your engine is destroyed.

You Destroyed it.

Reason #1:

Thread http://www.skylinesaustralia.com/forums/Dr...39#entry4010239

today i fitted a jap tuned ecu an dynoed to see the results

If you had of listened to advice.....

AFR of 9 is just too rich. That why when you drop the pressure, your ratios are getting closer to what they need to be.

You mentioned that you fitted an ECU, but did you tune it? Sounds like the injectors are too big for the program. Retune should do it.

The higher fuel pressure will atomize the fuel more, creating an even air/fuel mixture, therefore a cleaner,better fuel burn.

Your engine would still be OK.

Reason #:2

Lets quote some parts from this thread.. they key issues...

I recently installed a mines tuned non programmable ecu,
it made the car lazy going to about the same readin as before AN IT STILL PINGS!!!!!!
Also i tried to richen it up in that area with an safc2 -it retarded it by one or two degrees but IT STILL PINGS!!!!!

You ignored good decent advice given to you from a well known forum member...

you are using 2 bandaid solutions and 1 monitor only device

throw all of your devices in the bin and buy a real ecu

failing that, if you insist on keeping it, get rid of the mines ecu and use stock ecu

then get the safc tuned properly.

Had you have listened to Paul, (very clever fellow - just look at what he has done for the SAU community) your engine would still be going strong.

Reason #:3

Can the vtec signal from the neo be used somehow to switch nvcs on an off at specific rpm's

okay, Who knows what else you have been playing with in your travels... anyones imagination could probly tell a accurate story.

Your engine has been toasted because you put it through hell.

The good news is, rb25's are getting cheap, I will even sell you one for $1,100 :)

Good luck with getting it all fixed up, and try and take our advice next time.

^ not only are you the 'mad professor' but also 'inspector cluseau'...great detective work 'Tony'

id say the post above should be nominated for post of the year....top stuff

yeh ill do a compression tom........... but i think i'm screwed anyway!

Does anyone know if the head and block from a stagea 25det is the same as the skyline?

I sourced one already an was thinkin bout transfering all my externals including gearbox, sump, ecu and harness to it

Will the stagea 25 make the same power and will my harness(s1) work on this block ie. knock sensors,cas,injectors etc.

And yes i searched!

oh..... and guilt toy i did take the advice I got rid of those ecus a log time ago i think it only lasted 2 days in the car just to try them out. And i did also raise my fuel pressure back to about 30psi.

I suspect it was the over heating that did this.

Pinging the engine just ONCE is enough to do damage to the engine, even though the damage was not noticed straighta way, sometimes it can take some time before the engine stuffs up after a detonate.

The stagea rb25 is different, there are some modifications required to get it to fit. where are you located? your better off getting another engine from a R33 skyline. much easier.

What "fitting" modifications u refer to other than the sump?

My main concern was the difference in the head if any at all An as i said i will be using the r33 harness and ecu so should i get the same power? R33 is kinda scarce right now.

I live Trinidad and Tobago WI (huh! i know google it)

you have to mod the 25 sump, and you have to make a new oil pickup for the oil.

it can be done, my mate has done it before

Only about 1bar south of where it should be. :P

Good work inspector. Bad work smelly.

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
