Have had a bit of time to work on the car lately so an update:

A few parts i had ordered and bought of fellow members all arrived at once which meant i could start work

20140602_105741.jpg

Started with the oil filter relocation, so took off all the factory oil cooler and adaptor stud. Put in a Raw Brokerage adaptor stud, adaptor plate, speedflow 10AN fittings including an adaptor for the factory pressure sender so i dont have warning lights on the dash

Then was installing the plenum, Greddy copy

Fuel rail, after cutting off the extra fuel supply line not needed

20140604_161909.jpg

Whist waiting to pick up an injector cap, which the shop broke and failed to tell me when they were flowing and servicing the injectors!! Either way replaced the valve cover gaskets. Not sure if this is clean for an RB25 or not but looked pritty good to me. Not too much build up of old oil at all

20140606_103034.jpg

Injectors plus harness on, now have the last cap on there too

20140605_165758.jpg

New NKG BCPR7ES.11 spark plugs, coil packs back on and my engine is more complete than it has been for weeks!!

20140606_110126.jpg

20140606_110824.jpg

Now fitting up vac hoses and remaining hoses. Have a throttle body adaptor sitting here too, however when pulling apart my throttle body the hoses on the bottom of it are rusted closed so am after a replacement if you have one.

Whilst on that can anyone tell me where the two small hoses on the throttle body run to?

Have also bought all the required parts to move my battery to the boot. Will be using an isolator switch to hook up new and old positive cables. Have a 100amp resetable switch which i will bolt close to the battery.

Installing that will involve me pulling out the interior too, so i can get it neat and tidy, plus will be pulling out all the interior anyways so may as well do it all at once.

So thats where it is as of now, will be continuing to work on it when ever i have the chance

Cheers

Good progress mate. The hoses you're talking about on the throttle body sound like the coolant lines, if they're rusted up just clamp them in a vice and pull them out, they're not needed. I think the idea was to keep the throttle body warm in cold climates to prevent the butterfly jamming. Just make sure you blank off the hoses.

If you feel like tidying things up a little more you could extend the injector plugs and run the loom under the manifold. And turn the fuel reg around and poke the return line up between the runners.

Ah, when i was looking at it again that makes alot of sense. think i saw someone else just block them off too, cheers.

I was thinking that when i was putting the injectors back on, good idea!

Hooked up a few more hoses today:

20140609_120032.jpg

Fuel and some vacuum hoses. have one outlet left, im wondering if its for the throttle body (top right of the throttle body outlet). if it is ill just block it off. Have put the aftermarket boost gauge line in the a T piece coming out of the factory boost gauge line.

20140609_120024.jpg

20140609_120009.jpg

Found this dual boost controller line like this:

20140609_114204.jpg

So will have to figure why is wasnt plumbed up.

Stripped out the boot, has had water in it at some stage, bit of surface rust so will sort that. Standard fuel pump booo!!! So will put a Bosch 040 in there soon

20140609_131757.jpg

20140609_131753.jpg

Started to strip out the interior too, got the seats out then it started rain so only have the before pics and will continue to strip it out this week when i have a chance

20140609_131717.jpg

20140609_131730.jpg

Work continues, cheers!

Not sure what the vac nipple on the throttle body is for, mines blocked off though.

Should have vac lines for fuel reg, standard boost gauge, actuator, BOV, AAC, PCV and brake booster from memory.

I'd just run a single stage boost T, and get rid of that hose with a screw in it as it will leak. Also good idea to pressure test the intake as you will probably find boost leaks you would not otherwise know about, may as well sort it all out now.

Ive read that its possibly for a boost controller of some sort, or boose gauge. not sure how accurate it would be!

I think ive missed the actuator vacuum line! will check it out and fix it up, have the others hooked up though which is reassuring. Was going too hook the hose back up to the boost controller, again reading about them- they help with boost eg more consistant and on sooner so will work it out to get it working correctly, plus it was already there!!

Whats a good way to pressure test the system? Should have the piping and cooler done within the month, im guessing ill need a complete system before i do the test.

Need to fill all the engine oil, coolant fluids and bleed clutch, brake systems so will have a bit of reading in the best way to do these. So many differing opinions on that type of thing!

I got a PVC plumbing cap from Mitre 10 and drilled a hole in the end for a tyre valve, then used a 2.75-2.5" silicon reducer to attach it to the cooler piping. Make sure you clamp it properly so it doesn't fly off when you pressurise it, 10-20 psi is plenty. It was then pretty easy to hear/feel any leaks, can also use soapy water. I found that even with all boost leaks fixed pressure would still drop slowly, I suspect it was getting past rings, so don't spend hours looking for leaks if yours does the same, any boost leaks in intake will be pretty obvious.

Bushy, you mentioned that one vacuum line from the plenum should go to the actuator, is this cabled up wrong or am i looking at the wrong part haha. Still getting my head around RBs and turbos (NA V8 background)

I didn't realise you've got the brass fitting on the compressor housing, in that case you don't need a vac line from the inlet manifold as well.

I've got no idea now that dual stage manual boost controller works so not sure if it's setup properly. I just have a single stage boost T that is inline between the inlet manifold and actuator (or compressor housing in your case). Someone else will have to chip in here.

Ah, perfect thanks mate. think ill just block it off. Seems like there is nothing else that needs to have a vacuum feed on it.

After going on the turbosmart website, seems like its hooked up correctly (when the line is hooked up) so not sure there. It does need a computer and tune, maybe thats why it was disconnected.

Finished up the battery relocation. Came up pritty well and nice and neat. Works perfectly, including positive action on the circuit breaker and cut of switch. Used the cut off switch as a way to link up the new positive cable with the existing cable. Was a bitch to get it in behind the fuse box like that but got it done!!

Cut off switch

Earth strap, seems to earth it all well when i tested it with the multi-meter

20140618_142540.jpg

Finished product!

20140618_142531.jpg

Quick look of how the dash looks at the moment

20140612_171120.jpg

Also in some of the pics you can see the interior is now stripped. Will put some of the dash back in, up to the front of the gear shifter. Have it all out so that i can get rid of all the glue and sound deadening using dry ice, another job on the list!

Also have the throttle body all hooked up ready for the piping to get made

Few more jobs out of the way.

Installed the lock bar after removing the Hicas. Found it like this:

20140622_114320.jpg

20140622_114432.jpg

With no lines going to the engine bay, win job half done! Explains the Hicas warning light too. When the conversion was done they must of kept the non-hicas power steering pump on the engine and just not hooked it up, works for me.

Lock bar on:

20140622_135049.jpg

Just have the wire to cut so i done have a warning light.

Pic of the diff, does this look like a standard R32 diff? Im not sure what it is, would be great if someone knew, has these markings on the bottom of it, 94 represent the year? Would make it an R33 of some sort im guessing

20140622_114421.jpg

While I had the car up on 4 stands had a look underneath, tail shaft looks pritty new. Im guessing this is a custom one to make it all work with the gearbox

20140622_143726.jpg

Pic of the exhaust while i had it off, its bluddy massive

20140622_144018.jpg

Bigger rear sway bar, another win

6ccd1629-486a-4b5e-8462-b30bdfdad17f.jpg

20140622_135121.jpg

Can anyone confirm if this is a R33 gearbox?

20140622_143711.jpg

20140622_143705.jpg

Chipped off some of the sound deadening so i could get the dash back in, when doing the whole car ill get some dry ice. Quick coat of paint, then got most of the dash back in. no pics as it got dark very quickly

20140622_160645.jpg

Yep, looks like a r33 gtst gearbox to me (from the outside at least). I have seen a fair few in my time.

If you want to control boost cheaply and reliably, you can throw in a turbotech boost tee in between your actuator and pressure source.

The turbo looks like a china 400-500hp job. Depending where they come from, some people have been running them reliably. Others have had disastrous endings. I would replace with a kinugawa or holset for peace of mind.

Yes, the tailshaft would have been altered to suit the longer r33 gtst gear box.

That diff looks factory r32 gtst r200 from the outside. I cant confirm from the castings though. Castings generally are not a real good indication in knowing, as people tend to change the centres for aftermarket items. Perhaps the most important thing about the diff is knowing the ratio and whether it hooks up both wheels.

R33 r200 diffs usually have a different back plate (mostly interchangeable with other nissan diffs), so if it looks like its been resealed recently, there's potential it could be a different diff or perhaps just simply opened up.

You should have an orange 'viscous lsd' sticker on the side, which could be covered in dirt

    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
