I replaced the whole exhaust and intake, (yes even the intake piping from the throttle body) have a pod + heat shield. Got Tein springs and wider rims. I also had to replace the coil packs so i have brand new coils..

Only thing i haven't done is a tune, is there much a tune will do with such basic mods??

Btw its an R34 so it should adjust a few minor things by itself i think..

I'd be keen to do something else as long as it doesnt cost more than $2k (unless it gives an impressive increase to performance then i would look at spending more)

hey mate, im in NZ also, ive done all the same mods and after getting some advice from a couple of people on here i reckon the next best upgrade is gonna be new cams, especailly if you got a 2k budget!, but from what ive read our r34's will also need gtr solid lifters or soemthing like that, plus labour, so now cams is prolly tipping over 2k :D but they are supose to be good for like 30 kw with a good tune??

right now im just focusing on cleaning up the engine bay and trying to make the car lighter anyway possible with future upgrades

well the ecus are capable of learning small mods like intake/exhaust by itself and adjusting...even if you reset the ecu so it learns how u drive i hear people saying that the car drives slightly better.

not to sure how much increase a emanage blue + tune will get you i still want to find out myself.

after all that not too sure what direction to go in mods..theres a topic all the top of the n/a section which tells you all mods you can do..

heres a good read for you

A guy was selling his R34 GT-R cams a while back and he said that they might be able to fit the rb25 (de and de-t). I'm not sure if thats true or even if they would be ideal in an N/A setup

ALSO

Is there anything cheap on the list below:

* Motor (shave the head and/or block to increase compression)

o Head

+ Port and polish (remove restrictions in the head)

+ Oversized valves (allow more air to flow)

+ Cams (regrind, intake and exhaust side to improve breathing)

o Gasket (thinner gasket to increase compression ratio)

o Block

+ Pistons (increase compression, light weight)

+ Crank (light weight)

+ Rods (increase compression)

Wouldn't mind having more bottom end torque/power as i don't like revving high lol..

And on a slightly different subject, what would i need to replace if i wanted to restore lost performance (my cars done just over 104,000 ks now) and doesn't seem as responsive as it was when i had it at 56,000ks

Edited by R34 -_-

heard about advancing the timing/ignition or something which is suppose to increase peformance.

cams or cam gears i think are $100-200 only 1-2kw i think and the other is real expensive but boosts 30kw as someone said above.

The R34's advance and retard the timing by themselves to the furthest point before pinging occurs. I'm sure you can hear it when you turn the car on (inconsistent idle for a few seconds), its especially noticeable when you disconnect the battery and restart the car.

2 words, 'cam' and 'belt' lol, mine is about 20 thousand over due for a change and i cant wait to get it changed, (will be done very soon) but i just changed the cam belt on my much smaller and more economical daily driver and its about a 500 dollar job but felt like a whole new car after(was 64,000 over due from previous owners) , way quicker and more responsive as the new belt puts the timing back in place

p.s. i know my car is way over due so dont grill me to bad lol, just got away on me with other upgrades and i only have time to drive it once or twice a week anyways cos of work atm

lol yea i got my belts and water pump changed at 100,xxx ks. Felt better but still not how it once was lol.. My belts were f**ked when i changed them, how the hell did u manage to get away with so many ks?????

im not sure ay, lol, im originaly from canada and nobody back home ever seems to change cam belts, but yea, i never should have let it get so far over, but i wont be driving it more then a few hundred km's before i get it changed so fingers crossed,

what oil u running? a thicker oil could help compression (lots of threads here on that) or the throttle body might need a good clean out, did you change plugs when you got new coils? cos ur plugs will be just over their limit now, i just changed mine with my coils and they were buggered

Edited by AYW550

iv tried 10w50 and usually use 10w30 but they all perform pretty much the same. Might check out the throttle body tomorrow. Only thing i can think of that would help would be to get a strip of self adhesive heat shield on the intake piping (as it is directly above the headers) and clean my pod filter as it has a few bugs and dust stuck to it.

and yes iv changed my plugs twice since iv had the car.

Edited by R34 -_-

I experienced a lot of intake pipe heat after doing my turbo conversion without a heat shield on the manifold and turbo. yes I had a silicone bend on the intake and that was the part that was too hot to touch on the underside, but after using ACL Heat Shield Material over the headers and turbo, combined with boxing up the pod filter, my heat soak issue has decreased "dramatically"!

Before heat shield, leaving the motorway and back on to the main road = a car that was gutless in comparison to how it normally drives. Now it still has that go in it.

HPC Coating your extractors and wrapping them (do it the right way so you don't go corroding the extractors) will help keep engine bay heat to a minimum ensuring everything operates efficiently, and will also help the exhaust gasses escape quickly to increase power. With N/A power, I would suggest that method should work effectively and also help increase power delivery while you're at it.

Here's a pic of my heatshield. Not much to it but it works wonders! Also covers my dump pipe as well and helps keep my turbo lines away from that hot manifold!

From this angle you can see how I've curved it over the manifold creating a bit of a barrier between the rocker covers. The N/A Manifold will probably be slightly different, and I don't know how you would go bolting down the heatshield material (I used a factory turbo manifold so I was able to use factory bolt holes).

...and a link to the product itself: http://www.aclperformance.com.au/prod_heatshield.htm

Its construction, consisting of a ceramic filler sandwiched between two 0.15mm aluminised steel sheets, gives a very efficient high temperature thermal barrier suitable for a wide variety of automotive and industrial applications.

850-900 degrees celcius. $48.50PP on eBay for a 700mm x 290mm sheet. I had enough do do the manifold and still have a couple of decent squareish pieces that I'm yet to find a use for.

hey n-dawg, ive been thinking of wrapping my extractors , is the only way to prevent the wrap from causing corrosion to have them HPC coated first?

i tried painting mine with woodstove paint rated to 650 degree celsius and was recommended on the can as being good enough for manifolds but its already flaking off :D

Slightly off topic but oh well, does the factory R34 Aero side skirts fit on series 2 R34? (2001 face lift) I just bought a pair today and noticed that they are a bit different than my current ones... doesn't look like the front inserts will fit

    • Must have been an absolute nightmare to drive when the power steer was out, the rack ratio/wheel size/caster is all set up for power assistance
    • Welcome to SAU, what are you looking at buying?
    • I checked the injectors again (1 and 2, since they’re easiest to access) to make sure they weren’t clogged. Even though the entire fuel system had been cleaned, I wanted to be certain. Everything looked clean, so I reinstalled and connected everything. When I started the car to confirm everything was okay, it immediately revved up high, so I shut it off straight away. I checked to see if I’d missed a vacuum hose or something, but everything was connected. On the second attempt, the car ran without the high idle, but I noticed a distinct “compressed air” sound coming from the engine bay. Tracing the sound, I pushed injector #6 forward slightly and the noise stopped — it turned out it wasn’t seated properly, despite the fuel rail being bolted down. While holding it in place, the car idled steadily without stalling and ran for over 5 minutes. At this point, I pulled all six injectors out just in case I hadn’t seated them correctly or dirt had gotten onto the O-rings. Unfortunately, I discovered that I had damaged 3 out of 6 injectors (the OEM 270cc ones) during installation. So yes, this was my fault. Since only the pintle caps were damaged, I’ve ordered a Fuel Injector Service Kit from NZEFI to refurbish them. In the meantime, I reinstalled my new injectors – the car now idles fine for over 15 minutes without stalling. I have not attempted to drive it so far. It’s not perfect yet, as it hesitates when the throttle is pressed, but it’s a big improvement. Unplugging the IACV with the new injectors idles at around 800rpm, even with the IACV screw tightened fully. But this is probably due to tune.
    • I wanted to try and preserve the front bumper as long as possible, they're not cheap and are made to order in Japan. Taking inspiration from my previous K11 Micra build where I made an undertray for the Impul bumper, I did the same for this BN Sports bumper but a little slimmed down.  This time round I only made a 'skid plate' (if that's the correct wording/term) for just the bumper surface area, the Micra version covered the gap like an undertray. Starting off with a sheet of mild steel approx. 0.9mm thick 4ft x 2ft in size. I traced around the bumper, cut it out and cleaned the edges. Luckily I was able to get two halves from one piece of metal In the video I installed it as is, but I've since then I've removed it to spray and add a rubber edging trim. The rubber trim is suitable for 1-2mm and it's a really nice tight fit. The bolts had to be loosened due to the plates being too tight against the bumper, the trim wouldn't push on I used some stainless M6 flat headed bolts for a flusher finish (rather than hex heads poking down), I believe this style fastener is used for furniture too incase you struggle to source some. The corner's are a little wider, but this may be an advantage incase I get close to bumping it  The front grill got some attention, finally getting round to repairing it. Upon removal one fixing pulled itself out of the plastic frame, one side is M8 that fixes inside of the frame, where as the other side is M5. Not knowing I could get replacements, I cut down an M8 bolt, threaded it inside the frame along with a decent amount of JB Weld.  The mesh was replaced to match the bumper. One hole on the bonnet/hood had to be drilled out to 8mm to accommodate the new stud, once the glue had set it could be refitted. I think the reason the grill was double meshed was to hide the horn/bonnet latch (which makes sense) but I much prefer it matching the bumper Bumper refitted and it's looking much better IMO The Youtube video can be seen here: https://www.youtube.com/watch?v=bVZP35io9MA
    • The video for the servicing and fuel filter change can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44 One of the main jobs I wanted to do before the car officially went on the road, was to remove the awful looking blue silicone hoses. There's nothing wrong with having coloured silicone hoses, but I realise as I'm getting older I prefer monotone engine bays with a splash of colour on the engine cover(s). I cover this in a lot more detail in the Youtube video, so unfortunately there's limited photos of the process. The intercooler, upper radiator, boost vacuum and upper breather hoses were all changed to black silicone with mikalor clamps. The only blue left is a blanking cap at the back of the inlet manifold and the GReddy pulleys (which will be replaced for stock when the cambelt gets replaced) While the intercooler pipes were off I gave them a quick clean/polish too A before photo I do have a replacement air filter on its way. Fuse box covers were painted blue, they're now satin black Another job on the list while the bumper was off, is to add some mesh https://live.staticflickr.com/65535/54737966256_99b28bfa30_c.jpg[/img] I was hoping to use some thin wire to secure it, but it seems I've misplaced it and the wire I had was too thick to twist easily. I ended up using cable ties for the time being https://live.staticflickr.com/65535/54737131882_c2b7989dcc_c.jpg[/img] Was pleasant to see this https://live.staticflickr.com/65535/54737131627_8b2aab13b3_c.jpg[/img] The last thing to do was to fix the front grill and re-mesh that to match but I ran out of time The Youtube video can be seen here: https://www.youtube.com/watch?v=R4FsF6tgizE&t=23s
