Yeah I don't think they should have bypassed the upper line there, I'm pretty sure on my car that runs to the AAC valve and controls cold-start, not sure on the R33, would need confirmation :S

That bolt mod is also pretty dodgy :S

Oil pressure switch is to let you know when your oil is low

Behold, the fabled $100 (S)Exa, the missing cylinder is injector related, I can't hear a pulse and the loom seems shabby (loses another cylinder on moving) OK time for some TLC and boost!!!!

Oil Pressure switch? Hi-Power Racing are sorting that out for me, I think they're relocating it or something? I'll confirm all the details with the way they done the oil n water lines when I pick it up this arvo...I hope it will be this arvo lol It's getting catback done this morning then it's on the rollers for tuning. Coincidentally it's my car's birthday today, had her for exactly a year now!

Targa roof is pretty cool, though I got over it pretty quickly when I had my NX Coupe for 2 months lol Was a first car, affordable sporty SR20 run around :blush: What I liked though was that I could remove the inserts on the targa roof and use it like a sun roof :)

Edited by N-DAWG

Yeah there is a leak in the targa roof, I'm thinking of using silicone to permanently seal it. I'll never use it I'd say, too much messing around unlike a sunroof.

Fixing the loom up today, then engine is actually pretty good, just the rocker covers seals need replacing and a minor clutch line leak.

^ minor issues sorted = turbo it sooner :D

u need a turbo for ur conversion??

got a vq30det lying around u can take for $150

May be a tad laggy on the 1.8, I've actually got a GT28R lined up for it if I don't change my mind in the mean time.

One things for sure, tons of intercooler room, the front has a giant void!!!

Got my Skyline back today!

Man it feels different!! It's been tuned for 7PSi at the moment, the boost is doing something very weird...at first the tuner thought it was the front wheel but he checked it and it was fine...so a EBC is going to be next up in the future to be able to smooth that out and run bit more boost.

The other thing is that without the factory crossover pipe, they weren't able to run the factory BOV, so it's running without one which whilst sounds good I still plan to plumb it back in with a blumback BOV. The tuner agrees that it's best to have a BOV, but seems to think it's safe to run it how it is...

Took it for a fair bit of a drive, didn't really thrash it as such, still getting the feel for it...took it from slacks to mt gravatt around the block, up the lookout, then stopped on the side for a while car still running...and noticed it started idling strange, almost sounding like a rotor rev rev rev rev rev... and shaky... thought maybe it's just the way it is at idle, went to drive off, and still shaky and revs sounding almost like a WRX... Does this sound like coilpacks? Or maybe something not quite right with tuning?

I called the workshop and they said to bring it in, they doubt it's the tune, but they said to bring it in to check it out...

So now I've gotta wait it out till tomorrow morning now :S

Yep sounds like the packs are starting to go WRX noise is the giveaway. Also BOV is a must, I can't explain how shit my car feels with the BOV not working, you lose massive amounts of power between gears as it takes more time to get the turbo up to speed.

Yeah just done a search for coilpacks and found eleventybillion and one threads all with my car sounds like a WRX damn...more money lol

Looking at Just Jap ones for $399...or should i spend the extra on super spark or splitfires? I've heard the justjap ones are as good...

It will be interesting to see if it's still doing its WRX impersonation tomorrow morning lol

And yes I definitely want to get a plumback system soon! The chatter sound is kinda cool in a way, yeah it gets the looks n all, but also not the looks I want.

Well tomorrow morning I'll be taking it down to them for them to check it over as I said I would...then if it's coilpacks and they have reasonably priced ones in stock I'll just change them...otherwise it means ordering them.

Is it safe to drive the way it is?

Yeah I'd pay the extra $100 and get Splitfires, I've had a set for 3 years now and haven't looked back :P

The car is safe to drive, it's just annoying that's all really.

What turbo did you end up going with? If it's the stock turbo, your car will be huffing and puffing all over the place haha so much boost so early :blink:

oh yeah did they trick the baffle to stay open all the time????

Hey guys,

just thought I'd share my recent experience doing my NA->T conversion...

Well over the past few months I have been gathering up all the required bits and pieces to do my NA->T conversion... just picking up bits as I came across them cheap, etc.

Anyway, took 2 weeks off over xmas/newyears and spent a fair bit of time out in the garage ripping my engine to bits and then putting on all the turbo bits.

I actually picked up a blown R33 S2 RB25DET engine (broken rod) really cheap, and used heaps of bits out of that.

The water supply for the turbo was T-pieced into the heater line just before the heater tap, and returned into the block via the standard banjo fitting... my block had the hole there but just with a blanking bolt in it... Oil was taken from the oil banjo on the block, again which had a blanking bolt in it, but for some unknown reason the oil return WASNT there... I had to tee it into the head oil return line, so I put a much bigger fitting on that line to cope with the extra oil.

The engine came with the stock dump pipe which I used, and I picked up a pacemaker 3" front pipe off the forums. I already had a full 3" exhaust system sitting in the garage which was on the car when I bought it but was too big for N/A (not to mention incredibly loud and droney) so this meant I had 3" all the way from the dump.

I looked at swapping the injectors over without removing the plenum, but it just looked like too much stuffing around, so I decided to swap the plenum over to the turbo one as well... though in reality the only real purpose that this served was to provide a line to control the factory blowoff valve and somewhere to connect up my boost gauge!

I made a custom pod box and used flexible intake hose from the AFM to the turbo, and bought a CoolingPro FMIC with piping to suit. I just had to get one little piece of piping (turbo to cooler) made up and that all just worked.

I grabbed a TurboSmart manual boost controller and hooked it up between the FMIC cold pipe (already had the nipple) and the wastegate actuator, and wound it right out to basically nothing (i.e. just whatever the wastegate spring would hold) for the time being.

I bought an eManage Blue a while back, but it was second hand and had the loom for an S15/200SX. I figured I would just chop up the loom to fit the 'line. Clearly I wasn't thinking too much at the time... but didn't click that that was only 4 cyls. So I couldn't actually hook up the injector or ignition harnesses, just the AFM (and tach, etc).

I hooked it up, entered the injector size values and exported the blank map to the unit.

Now it was time to actually start the engine! Of course the battery had gone flat as I'd been running a 12V worklight off it, so I had to jumpstart it, but to my excitement it kicked over straight away and it all seemed good! (actually... to be honest I had a massive exhaust leak which turned out to be that I'd forgotten to do up the dump-front pipe bolts :blink: did them up and it was all good!)

I noticed it sounded like it had a bit of a miss at idle, but just figured that would all be sorted with a tune...

Anyway, put the front bar (cut the reo to fit the cooler and cut the 'mouth' of the front bar (R33 S1 Type M) for better airflow... and coz it looked awesome!), headlights, grill, bonnet, etc back on and took it for a bit of a spin (no tune yet, just the adjustment for the injector sizing...).

I can certainly relate to 666DAN's observation that it sounded like an electric leaf blower under there! I had the 'lid' off my custom pod box, but you could hear it spooling up soooo loud! And the BOV noise was incredible :P

Now, because I hadn't had it tuned yet, I knew I couldn't push things, but even so, it was like a totally different car to drive! at say 1/4 to 1/2 throttle off from the lights it would move off fairly gently and then just start spinning up the rears as the boost built!

Once or twice I put the foot down fairly hard and under load it started to ping/knock... so I immediately backed off!

Anyway, went for about a 30 minute drive, on the way back I stopped at a set of lights, they went green, I put the foot down (but not hard enough to loose traction) and looked in my rear view mirror to see... well... nothing actually... all I could see was blue smoke. I couldn't even see the car behind me. :blink:

I took it fairly gently from there home... I got home, popped the bonnet and it really sounded like it was running on 5 cylinders. Not good!

I decided I needed to do a compression test. Removing the little hose which connects the oil breather on the two rocker covers showed lots of oil... out of interest I removed the FMIC hot pipe and saw LOTS of oil. Not a good sign!

I grabbed a compression tester and tested each cylinder...

200 - Wow! better than I expected!

200 - Very good in fact!

60 - Ah. That would be the problem!

200 - Okay

200 - Still Okay

90 - Bugger!

So that's where I'm at. I was a little worried at the start about putting a turbo on an engine that, while it seemed to run well, had done over 180,000kms. I'm thinking it might have already had low comp on one cylinder (hence the 'miss at idle' I noticed even before I ever force fed it...), but now it's certainly got two down!

Ah well... time for a rebuild, I say!

Yeah splitfires I think will be ther better way to go...spend bit extra now rather than more again later.

I took it in this morning, it's 99% coilpacks, but they want to diagnose first just in case it's an injector, before I go and fork out on coilpacks. Coil packs seem to be fairly straight forward to swap, i've seen the DIY for them so at least I can do that myself.

Ended up going with the R33 Series 2 Turbo, it's only running 7 psi, so it's definitely pushing a lot more power than before though! The boost graph was quite wavey though so no more boost till I get a EBC and probably a plumbackBOV, I think I'll be over having the flutters after a while lol

But yeah the boost is there very quickly! Exhaust has a nice deep sound to it when i put the foot down, but for normal driving it's quite good not too loud, and if I get to my cruising speed around 60-70km/hr take foot of throttle she just rolls very very quietly! Just the flutters are obvious though unless I shift at 2k revs. I've got a tiptronic auto box.

The intake plenum hasn't been modified, maybe something to look at later... for now I'd rather have been spending money on an EBC rather than coilpacks, guess I'll be trying to sell my unused parts quickly first. Costs add up very quickly when doing a conversion.

Coil Pack 3 = Dead

They threw in a coilpack from an R33 Series 2 in the meantime to help me out till I can get some Splitfires.

For now i'm just gonna see how she goes, I don't want to go for too long a drive in a hurry, particularly with long weekend coming up n all, hopefully I won't have any more dead coilpacks in a hurry!

$100 for more splitfires over jjr direct ignitions; show me where please,

cheapest ive found is $615 + delivery on ebay where as the jjr ones are only $399 WITH 1year warranty.

please show me where i can get them from and ill ditch my JJR and get the splitfires right away :laugh:

ndawg, told ya it was the pack lol.

you can run the boost tee but a ebc is sitll always better.

Sorry, around $100 more than say superspark lol

http://www.skylinesaustralia.com/forums/Sp...mp;hl=coil+pack

Cheapest i've found.

Heard not so great things about superspark, and heard mixed things about the JJR ones...so i'm just gonna look at getting splitfires straight up.

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
