Received word yesterday arvo (xmas eve) that my head has quite a few issues (broken valve guides etc) and is going to set me back ~$2500 for a refresh :-/ seems rather rich and I know of a head freshly port & polished with oversized valves for around the same $$$ so may as well head down that slope (by god it's a slippery one ;) ) 

On top of that there appears to be a bit of scoring in cylinder #3 (enough to catch your finger nail) and already being bored to 87mm i'm at a little bit of a crossroad...

Mechanics on holiday til the 7th so at least i have a bit of time to think about it (research)

Merry xmas to me :34_rolling_eyes:

What happend? Did the timing belt skip a bunch of teeth?

Is anyone taking responsibility? 

Get a 30 block mate. Bin the 26

None of the above... :-/ Car was actually driving fine and only blowing a little smoke which I put down to valve stem seals or rear turbo seal...

Only reason for pulling motor down was precautionary... adding head studs, oil pump gears, metal head gasket etc...

I did buy the car knowing it had a forged rebuild but done by a shop who doesn't specialise in Jap cars so i knew when buying I was taking a risk...

I do have a 30 block sitting in the shed that's been there for years but everything I've purchased to date (specifically turbos) has been based around the standard displacement RB26... so i'm kinda dedicated to that now...

 

Looking in to sleeving just that one bore, I'll take a UTT set home from site this swing and check bore thicknesses...

 

  • 3 weeks later...

So I've stripped the block and it's being sent off to see what we can do about the scoring... Bore is already at 87mm...

Pictures are cylinder #3

Least i got a second Xmas opening up my goodie boxes :34_rolling_eyes:

Keen on selling the RB26 head? 

was contemplating selling it yes as i've just picked up one ready to bolt on already ported...

though i have an rb30 sitting here i was contemplating building up one day :7_sweat_smile:

The mythical 'one day' haha, in my experience that day is forever just around the corner ?

Let me know mate

haha, you're not wrong there ;)

 

you're welcome to pm me what you'd be willing to pay considering the damaged valve guides and obviously shipping....

nope, still nothing as of COB today :34_rolling_eyes:

I lose motivation to follow this stuff up whilst i'm 3000kms away :7_sweat_smile:

Though my turbos actually turned up today (ordered late October 2018 after being told they were 'on the shelf') After reading @Dose Pipe Sutututu post about sparesbox and the guy having issues with hypertune it seems i'm certainly not alone...

Sparesbox gets all their turbos from GCG. GCG generally have a small amount they carry as well.

They're a lying bunch of scumbags, their entire business works on drop shopping with the exception of service items which they keep in house.

Hypertune seems to prioritise shops over clients or those with a big market presence.

Just how the world works I guess.

    • Bit of a late reply here as me and my wife have been really busy with new born twins. I finally got these issues fixed and it was something really stupid that caused all of this 🤦‍♂️... After alot of mucking around with trying to figure out what is causing these issues, I back probed one of the R35 coils on the power 12v supply, with the engine running it got 25v! And I thought, hang on..., this isn't normal. Measured my battery with the engine running to check for over charge from the alternator and it wasn't that. So then I dissconnected the R35 PRP coil harness and backprobed the power supply on the engine loom where the ignition coil harness connects, with the key on ignition (engine off) it measured 30v! So then I had to trace where that high voltage was coming from and it lead me to the brown relay "ECM & IGN coil relay" inside the cabin next to the ECU on the passanger wall. This relay feeds power to the ECM and ignition coils. Tried swapping it with another same relay. nah still 30v.. coming from the 2 green/white wires in the brown relay. So then I set my multi meter to the beep continuity mode and probed every fuse on the fuse box inside the cabin to try and find this high voltage power source. Wasn't any of the fuses inside the cabin. Then probed all the fuses in the engine bay and BAM, got my power source that was a 10AMP fuse called "ENG CONT". Pulled the fuse out, and what do you know... it was blown. 🤦‍♂️  So then I quickly replaced it with a new 10AMP fuse, started the car and yeah haha [insert extreme face palm]... The RPM blimping thing went away, car idles smoothly now like what it was before. I swear! I checked all my fuses with my test light twice before I created this forum thread. I think, maybe because one side of that faulty 10A fuse lit up on my test light, I must have thought it was still ok and not blown. But now I know to have both sides light up on the test light when checking fuses... I hate diagnosing electricals.... I'd take mechanical problems over electrical problems any day🤣. Drove the car around my suburb with the engine up to operating temp and it runs fine like before. However, I notice that my fuel pressure is still at 49psi. So I'm thinking this must be normal for my system as I've upgraded the stock fuel pump to a Walbro 255L/h with a constant 12v mod.  But anyway, I'm just glad to have my daily back on the road! Thanks everyone for the replies on this thread, all sorted now! One thing I want to ask you tuner guys, my base fuel pressure on the haltech main settings are set to 43.5psi from default (my tuner must have not checked the fuel pressure maybe when tuning my car?). Do I set it to what it actually is idling on at 49psi? Or just leave it ("if it aint broke, don't fix it/leave it")?  
    • The max they would go for me is 50.
    • That cannot have been a fun set of drilling. The stock "baffle" looks identical to rb26, I just cut fuel cell foam to fit the full length under the baffle.
    • I understand your sarcastic exasperation. But to be fair - the baffles do indeed fit OEM cam covers. They did omit to say that you need to do a bunch of stuff. But they do fit them.
