Hi all,

Need help with the attach picture. Can u guys send me a pic of that exact spot or can I assume A connects to A and B to B as per the pic?

Can't believe a f**king rodent can cause me so much pain and suffering and unwanted expenses!! [emoji35][emoji34]

And also can i drive around without those attach and i have no known issues of over heating ? [Till i have the connectors ordered and arrived of course]

Thanks!

No, they are not connected. top/black is a coolant sensor for dash, lower/red is a coolant sensor for ECU. the things you marked b are earths.

I don't know which colour wire from the engine loom needs to run to each, but you may be able to tell from the remaining wire at the sensor/earth end.

Can you just get a new engine loom? And what is it, 33 gtst?

Oh btw if it starts and runs, yes you can drive around without them. It won't run properly when cold (because ECU won't know it's cold) and your dash gauge probably won't work

An engine loom will cost more. I mean they're also selling just the connectors so might as well utilise them?
f**king hell it's pissing me off...can anyone send me a pic of theirs so i know what connects what?

This is from a rb25det.
i won't be doing the work. Will send it to a mechanic. And i am using a power fc too if that makes any difference...

I can't help with a pic but hopefully someone can.

The only connector you need is for the coolant temp sensor (red). You have the connector (black) for the dash sender, which it may not be repairable due to not enough wire, it can be replaced with a simple crimp connector. The earths are also crimp connectors so nothing special there use a 10mm spanner or socket on the bolts to disconnect them

The other part to this puzzle is the wires at the end of your engine loom that used to go to those connectors. Do you have a pic of the end of your engine loom?

In any case a reasonable mechanic or auto electrician will sort it out

OK, so assuming it starts and drives, you take it to a competent mechanic, (it will probably run poorly when cold so let it warm up for say 5 min). They will say "holy shit, what's this mess", you'll tell them to fix it, they'll pull back the engine loom wrapping far enough to see the colours and will match the wires in that loom to the remaining wires at the manifold that you've pictured, they'll rejoin them all (probably 5 or 6 in total) and everything will be happy again.

do you have a hand controller as well? If you go under sensor check you can see which sensor is causing the check light.

my guess would be it won't cause the light because it would just read a broken wire as some sort of very low temp. but that's just a guess....

It should be looking for a voltage (usually between 0.5v and 4.5v) and anything outside that is a sensor fault (short circuit would be 5v and open circuit would be 0v)
Fairly sure this will show up in sensor/sw check but may also give a fixed, incorrect value as well as suggested

I don't have the time to check yet as car isn't with me. .. so saying that. .. the car will trigger the engine check light? ?

      "Cheap" bolt on turbo on RB25DET NEO

      By GTSBoy · Posted

      The HG high flow is excellent, and costs about the $$ you're talking about. But it, and probably every other highflow, uses a diffeent core than the original turo, and the original Hitatchi core is quite long. So, I think it is inevitable that there is likely no such thing as a highflow that just "bolts on" with no other effort required. And the same is likely true for HG's outright replacement "bolt on" turbos (the ATR things). And the same is likely true for anything similar from elsewhere. I have no idea if the cheap Chinese/Taiwanese complete turbos from eBay/Temu/etc are as bolt on as they claim. I mean, they claim the bolt onto the NAs as well as the turbos, and we know that can't be "bolt on". But it wouldn't matter because I'm not buying a $169 4 psi turbo for anything other than a paddock basher.

      Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD?

      Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.

      So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!

      OK, few more things sorted and it is ready for a shakedown on 10-Oct, with one weird thing. Changed the run in oil and filter for the good stuff. 8l came out, about 8.5 went in with filter so that looks all good. Changed the starter (again), this time for a brand new one, works good. Interesting that the Taaaarks one is shorter than factory but spins harder, I guess electronics have moved on a little in the last 30 years. Will be nice to have a bit of extra space under there. Put the timing cover back on, and noted where the cam gears were set as a record.  Will need to double check the timing but it is pretty close. Also put the coil pack cover and intake snorkel back on. Exhaust Inlet Changed the water out for coolant, bled up nicely. Removed the rear brake pads (well worn factory sumitomo ones!), gave the hardware a good clean and reassembled. I've put bendix XP on the back again because the price is excellent at $150 a set and they worked well on the V37. Front pads have plenty so no issue there
