How Much Can I Make With Stage 1 Gtr34 Mods

[Longz]

Hi ! i am thinking of doing stage 1 performance upgrades for my GTR34 V Spec

Current mods on the car is only a Ganador Titanium Exhaust

i was thinking of geting a apexi power fc and hks ev5 boost controller

roughly how much will this make at the wheels ?

[Tangles]

300Hp at the wheels Id say (250kw)

[Longz]

seems preety decent

Any idea on what

Further stage upgrades i should do

Spark Plugs \ Intake etc

[Tangles]

a nice Apexi panel air filter for now

1 bar boost

bp6re copper sparkplugs, pre-gapped to 0.8mm, v-groove, $20 for the 6

perhaps splitfire coilpacks but see how your stock units go for now.

best of luck

hmm with the apexi filter i cant use the oem box right ? need to buy a new one for street use ?

[Tangles]

yes the panel filter will drop right in.

here is a Greddy one for $80

http://cgi.ebay.com.au/Greddy-Trust-Airinx...=item414dd9ec5a

injectors for under $600 delivered

http://cgi.ebay.com/ebaymotors/Toyota-Supr...=item27b0a5158f

coilpacks for $400

http://cgi.ebay.com.au/Performance-Coil-Pa...=item19b8125d38

Im using siemens 550cc injectors for my rb26 track car, got them from ebay usa new for $363 delivered.

z32 new air flow metres, $170ea delivered

http://cgi.ebay.com/ebaymotors/VG30dett-z3...sQ5fAccessories

Up to you if you drop in larger injectors or not, but IMO Id keep the intercooler standard for now, air box standard just with a topbrand panel filter,

Sparkplugs I mentioned are good for 300rkwk so definately grab them, cheap but perfect. NGK BP6RE .8mm copper

Power-fc tune will cost around $450, and your stock airflow metres (and coilpacks) should be fine up to around 280rwkw

Cheers for the info ! that has helped me alot !

P.S alot of the items say

for

BNR32 BNCR33 RB26DETT Engine

so i guess i need to find it for BNR34 ? for me

nope what Ive listed for you above WILL be fine for R34 GTR

panel filter, sparkplugs, injectors, afm's,

coilpacks yes - r34 gtr is same as r33 gtst, see here http://cgi.ebay.com/ebaymotors/YELLOW-JACK...eQ5fCarQ5fParts

you'll be right ! I got a set of yellowjackets for my r32 rb26 for $148 delivered !

if you do injectors, coil packs (if needed), air filter, new spark plugs, and z32 air flow metres, then tune the power FC for 1bar you should be right on 250kw

however new injectors, air flow metres and coil packs most likely are not needed for Stage-1 tune

all the best

go power fc d-jetro and piss those afms off

[Longz]

apexi power fc and d jetro any huge differences ?

apexi power fc and d jetro any huge differences ?

PFC 'L-Jetro' retains AFM and will accept range of AFMs such as Standard to Z32 units.

PFC 'D-Jetro' deletes AFM and use 2 MAP sensors on the inlet plenum - plenum will have to be removed and 2 holes drilled for the sensors to slot in.

For your power goal, get L-Jetro as it's pure 'plug and play' no piss farting around - you can even install it yourself in 30 minutes. There are couple of units up for grabs on FS section of this forum.

D-Jetro unit is $1,900 to purchase then you'll need to pay for plenum removal and drilling so that is $$$ job. Should you crave for more power when standard AFM decide to maxed out, just buy a pair of Nismo AFMs for $900 and it's 'plug and play' so saving lot of money in labour.

250kw at wheels, EBC isn't needed, just take out the boost restrictor off (will give you the boost pressure rated on actuators which is 14psi - located on drivers side of the engine bay, next to fuse box), decent quality panel air filter, a pair of cam gears and PFC + Tune (seeing you've already got exhaust).

Preventive maintaince such as coilpacks is a good idea (have read that few 34's have coilpacks failed), I wouldn't know if worth getting yellowjacket thing over decent brand as Splitfires.

Hope it helps with your desire for more power.

Talk to your tuner and most will tell you just go with PFC as the dejetro will take longer to tune and afm will generally give you better fuel consumption (dont know the details but 3 tuners told me this). But dejetro will be the way to go with you're after high power (in which AFM will be maxed out).

300awhp isnt 250awkw. It'll be close to 220awkw. 1 of my mates just tuned his 33GTR to 0.9bar and got slightly higher than 220awkw. In any case, you will see more than power figures when your car is professionally tuned by someone reputable (response being the main).

Sry for being off topic but you wouldnt have happened to buy your car from Camperdown did you?

Continued OT: Someone asked me that in my FS thread JDM..... co-incidence or is it some inside joke of some description??

[thrtytwo]

250kw is 330hp~

a mate of mine has a 33 gtr with 700cc injectors, PFC DJ, i think 1Bar and he has 350hp atw, pulls low to mid 12's at 1/4 mile

[R31Nismoid]

It is a R34 GTR - stay away from ebay crap please.

As for further upgrade forget coil packs, forget injectors.

Before anything else you need:

PowerFC/Tune

Cam Gears

Tot: $2,000

Then save up for:

Turbos

Injectors

Decent front pipes (2.5" minimum) & decent Hi-Flow cat

Nismo AFM's

Tot: $4,500-$5,000

Inside joke? I don't understand what you are talking about really. I asked because I saw a GTR for sale with ganador titanium exhaust from Camperdown, that's why.

[Longz]

Hi the car might of been at a dealer at camperdown as i was told by the previous owner it was bought from a dealer in the city. Its a midnight purple the previous owner sold it to me the previous owner was from blacktown

- With cam gears are the tomei ones good ? i was looking at

Tomei Cams

Edited April 15, 2010 by Tenkin

[R31Nismoid]

Cam gears are cam gears really mate. $470 is probably double what you need to spend.

Anything will suffice as they are just a gear with 3 bolts

Some of the SAU traders have some for around the $250 marker i think, get those.

[Longz]

Tomei are 5 bolts

anyone else's feedback on cams all being the same ? HKS , Tomie Etc
