rb25debt

Ok awesome, thanks for that

damn, So my only option is to get an aftermarket ecu? I was told neo ecu's can't be chipped?

Hi guys, i have a rb25det neo in a r32. Mods are: 3 inch straight exhaust Tial gate 7.5psi spring FMIC WALBRO pump Chinese t3/t4 turbo For some reason, if you slowly ease the throttle on it goes pretty good, Makes good power. But if you just plant your foot, the wastegate screams but but its slower. On the boost gauge it goes up to 10psi I have done a compression check and its algood, I have checked the wastegate diaphram and its algood also. The car doesn't miss at all. I'm thinking it could be a air leak because it will stall sometimes after you come to a stop. Any ideas guys? Also because its just the factory ecu with a Larger turbo i'd imagine it would be a problem but my friend has the exact same setup with the factory ecu and it goes really well.

Yea that's what i thought, i'll try find some to borrow haha, do you think it still could be the switches if the regulator clicks when i use it?

Hi guys, when i first bought my car only the drivers side window would work. One day i smacked the window switch in hopes it would fix it. After i smacked it, the passenger side started working. But then the drivers side stopped working. I have checked and tried two regulators and when i try put the drivers window down, i can hear the regulator click. Any ideas??

Never new this, i shall start doing this then

It has a aftermarket turbo on it and it has some random nuts. there is one 17 but the other 3 are 14s

Im replacing my turbo now but the nuts that hold it to the manifold are very weak and are starting to round, i can't fit a socket or a spanner completely around them because the nuts are placed so close to the inlet and there is not quite enough room to fit around them. I don't want to use a crescent spanner as im sure that will just round it

Awesome cheers guys, i'm going to have a good look tonight, luckily i have a spare turbo i can put on

So two days back i started my car first thing in the morning to warm up. I went inside and came back out after 5 minutes and noticed smoke lingering from my exhaust, it looks blue so im assuming its oil. I gave it a little revs and it stopped smoking, i drove to work, no smoke. On acceleration there is no smoke, it only happens first start of the day. There is no oil in my catch can nor is there any really in my intercooler piping. I am going to check the turbine housing for oil tonight. Does this sound like rings, valves or turbo? thanks guys

Hi there, Just wondering if anyone in Auckland can take a look at my r32 with a rb25det neo for me. It's not running right and i really don't know what's wrong. I will pay you and can bring to you. Thanks guys

its 1990

Hi guys, i have a r32 which originally had a rb20de in it. It now has a rb25det NEO. The problem i have is it came with a 320 speedo dash cluster and only the rev and gas gauge work, so it has to go. What dash cluster do i use?

Haha yea it is a frankenstein but its running alot better now, its all certed for the engine swap, has 4 pot front brakes and 2 pot rears and adjustable suspension. And i just got it a fresh warrant of fitness no problem haha

Okay great, the 4.6's are for motorsport uses? Would you know what ratio my current diff has?

I currently have a open diff and want to put a LSD in. I have a r32 with a 25det neo in it. What are your thoughts on this diff? i can get one for a good price. Heard they a good option if wanting better acceleration. But will it be too much for everyday driving

So it turns out because the shell is just a GTS, it still had the Rb20de fuel pump, i have got an aftermarket walbro fuel pump and i put it in and it's running alot better, i am going to try find a rb25det neo turbo and put it back to stock until i can afford a better ecu and tune. For some reason since earlier today when i come up to stop at lights etc, the car dies? could this be a air leak?

Yea i'm really confused, what is the engine from do you know? i'm taking it a expert tomorrow

Ahh good idea, yea i'll do that tomorrow, i also realized my bov isn't going off, it just compresser surges. as i said earlier it makes 8 psi boost but doesn't pull like it is. When i had the gate hooked up wrong and it was over boosting the bov was going off.

Yea it's still connected to the correct place it just had a hole melted into it. i taped it for the mean while

Sorry didn't see that i'm using my phone haha

would you know the ecu number i would need?

Yup says ov300, that would explain why its running so crap, doesn't like to boost. If i was to get a the neo ecu, would it be hard to swap over?

I have a r32 with a stagea rb25det neo. It isn't running right and im thinking maybe the ecu has something to do with it. The r32 is manual converted. The current ecu is 23740 0V300 I'm sure this is the 4wd auto stagea ecu. if my car is rwd and manual, would the ecu possibly need to be changed to a different ecu?
