before my turbo gets here i want to get all of my fittings ready so it all goes on at once. just a little warning:

DO NOT DO THIS IF YOU ARENT CONFIDENT. for a small fee Aaron from Sliding Performance can do all of these mods for you.

i took my turbo off a few days ago so i had all of the fittings laying around so i thought i'd start getting things ready.

i went to pirtek to get new washers which coast $25 for all new copper ones, and got some 6mm drill bits as well as some new circlips rings for the wastegate actuator (old ones looked a bit crappy), i got some 4mm and 5mm ones as i wasnt too sure which ones would work.

so i got to the banjo bolts:

the best thing to do would be to get them into a vice under a bench drill to get a 100% straight hole. if you've got access to something like this then go for it.

i didnt have access to one so i had to make do with what a vice grip and a steady hand.

this is how i held the bolt in the vice grip: (all pics were taken off camera phone)

make sure you're drilling is as straight. it shouldnt be too hard as the old hole should work as a countersink to get you started.

this is what the difference is:

the end result - two perfect 6mm holes:

so far thats all ive done, ive opted to have my oil line modified by Aaron but i might give it a go if i get bored.

dont forget the hard line too. thats if ya using it

yeah im getting Aaron to do that for me, or if i can find a place to do the brazing ill do it myself.

$25 for washers?

i got 8 all together @ $2.80 each which is around $22. i had to be somewhere so i didnt have time to cry over the price.

Good stuff Joe, whens the turbo get in? And which one did you pick?

I'm planning to get one for the R34 later on so would be interested to see the results you pull off.

im not too sure when it'll be here mate, but my old turbo was letting off a fair bit of oil so i took it off the road to be safe.

well i got bored so i thought i'd modify the oil line. you only need to modify the banjo fitting that sits on the motor, which on the oil line is the one closest to the loop.

i put the banjo fitting into a vice then centre punched it.

i got the 6mm drill bit out again and started drilling, making sure that it went straight down. im going to go around on monday or tuesday and try to find someone to braze it. ill find out how much it costs and report back.

a few pics.

i went and dropped off my oil line to get brazed.

apparently you need a brass plug to sit inside the 6mm hole, then braze around that so the braze has something to adhere to. its costing me $40 from an engineering workshop, theyre brazing and cleaning it all up for me to be ready to be bolted up.

i probably could've gotten it cheaper somewhere else but i wanted it done properly as im very pedantic when it comes to my car.

righteo.. ive got some pics of the end result.

seems though the oil lines arent copper. the guy i sent it to couldnt get braze to stick and thought it might be steel so he welded it as if he was welding to stainless steel, and it also isnt a copperey colour after he cleaned it up.. as you can see, it looks like stainless steel.

When i got my SlidingPerformance High-Flow, i was lucky to have a mate who works in an engineering shop, with lots of high-tech tools. He took it to work and i think used a TIG welder to fill the hole. I would recommend this technique to fill the hole, i remember brazing from highschool days and believe TIG would be HEAPS stronger. (looks like yours has been welded too)

Car is a R33 GTST. It has the Slide max oversize hi-flow with the VG30 rear on it.

The tuner was quite impressed with the results and the way the turb's performed

as he said by as early as 2200rpm it was at 5psi and by 3500 rpm it's at full boost

which in this case was set at 17psi.

nice figures mate! ofcorse i dont mind :P

thats the exact turbo ive ordered.

what supporting mods do you have?

Other mods are. Power Fc, FMIC, full exhaust, Nismo reg, Bosch 040, Z32 AFM and using

a turbotech boost controller which holds boost very well at that level. ;)

Oh and upgraded the clutch to a Exedy cushion button.

    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
