Plazaman plenum $1000

Throttlebody $250 - $500

6boost exhaust manifold $1100

Garrett GT3082 0.86 rear $1550

Wastegate $400 - $800

Intercooler $300 - $1200

ECU $1500 - $2500

Intank pump $200

Injectors $1200

Adj reg $250

Other bits and piece/tuning/labour etc $2000

This is a rough estimate depending on if you want to go 'brand' products or chinese-made generic......

I ran up a receipt log of $15000 when I hit 300rwkw and approx $30000 (and climbing) to the current 430rwkw with the 3 litre hybrid donk. Mind you this is cheap as I did a lot of the work myself, it would be a lot more if you calculate in the labour costs what a lot of these workshops charge.

Have fun with the addiction. Just remember 'Economy' and 'Skyline' dont appear in the same sentence !

there's over $3000 that is not even remotely needed for 300rwkw

lol how true!

i don't wanna add up what i have spent!

fpr is good IMHO...

and yeah, adding up, grrr Im at something like 20grand in parts, 18g for the car, then probably 8g for tunes, services, maintenance

4yrs and counting = $45k at least, lol

but she's my 15yr car, so 11 more yrs till the eldest can learn to drive :P

if you are buying injectors anyway then an fpr is a waste of time and money. the nissan one is well up to the job of flowing 300+rwkw

there are that many troubles with them that some tuners will not tune a car with one.... especially those malpassi ones...

Exactly. Aftermarket FPR's are more trouble than they are worth on most cars unless pushing big numbers or trying to be dodgy and get maxing out injectors to go that little bit extra.

Finally, I believe that your methodology for working out the power you want is all wrong. You are comparing apples with oranges as far as your 300kw Holden or Ford vs 300rwkw Skyline. Not only are you comparing a flywheel figure to a wheel figure, but the Skyline is also considerably lighter. You DO NOT need 300rwkw in a skyline to be quicker off the mark than a 300fwkw holden or ford.

Adding to this:

Don't forget that the skyline engine is far more advanced than the falco-dunny-door ute engines so the efficiency from engine to wheels would be less than the skyline, ie: they lose more power. so that 290kw might be less than the 218rwkw we usually calculate (30% loss).

Also they weigh what, 200-300kg more? Which smashes the power-to-weight ratio.

you will find the 4.11 diff gears plays a big part in how the skyline performs on the street

even a mild 200rwkw GTST will take down most street cars with ease and continue pulling slowly

this is why you may find you can beat "300kw" badged XR8's etc etc, they have the factory power, but the lateral acceleration isn't there

in my 192rwkw GTST ive had only a handful of cars actually beat me on the street

from memory a quick as auto vl, and a couple of non-non std xr8's etc

on a race track i was able to beat a clubsport R8 315 badged ute from 100 to 200kmh and continued to pull in front ever so slightly

Are you kidding?

You think your cast iron block skyline motor is "far more advanced" than Ford's quad cam V8?

How about Holden's allegedly power dropping 6 Litre V8 that only needs some breathing mods to run into the 12s NA?

Not to mention that rubbish turbo straight six Ford motor, that is only a couple of pounds of boost away from 300rwkw?

These are not carbie'd 253s out of a kingswood.

Try checking how much an LS2 puts out on a dyno stock. That crap about losing more power than a skyline engine is exactly that. Don't claim it to be a fact.

Dazza and Muzza have the technology now compared to R32/33/34.

Saying all that a skyzer around 200rwkw+ should give most *STOCK* Aussie muscle a damn good run; and thats probably a cheap and cheerful place to be.

it isn't hard to get power out of massive V8 engines even if they are built on caveman tech (holden v8), at least ford are putting some tech into their engines. (the new mustang 5L looks pretty nice and the factory provisions for a supercharger to bolt on, hopefully that makes its way into the XR8

i agree with Paul, my GTST when it was running 200rwkw would pull away from a friends 290rwkw LS1 powered commo.

I find that very hard to believe, something must be wrong with the commo.

I have a 190rwkw R34 and have raced my old mans tuned ls1 (~225rwkw). With a similar launch mine will get a nose in front and keep gradually pulling away. It does beat it but does not smash it. I would think a 290rwkw cammed ls1 would beat me no probs. I have driven a cammed ls1 and it definitely feels faster than my car. although i have never put them side by side.

Although I have seen a 225rwkw 1350kg commo sit side by side with a ~1700kg 300rwkw cammed ls1 car.

This is true, it's easier to get power out of large displacement engines, but we're also talking about a boatload more power than the old "caveman" V8's, ie. 308/350 302/351.

If only Ford and Holden did a "quality control" model XR6T/SS, that cost 10K more, but didnt have shitful appointments (rubbish leather for the main one) and finishing.

Make an XR6T motor happy to rev to 7500 or so, than bang it in a skyline and you could have some serious fun.

So uh yeah, put a highflow and supporting mods on your R34!

(apologies for off topic)

    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.      
    • It sounds like you want what the Toyota Landcruisers have for their roof racks. Wanna know what you end up with? Rust holes in the roof, and water everywhere...
    • Discovered today that if I select reverse first and take my foot off the brake, then select drive, the drive indicator light works and so does the tiptronic gear indicator. 
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Does anyone here have any ideas?   Cheers guys
