kakimoto cat back with hks dumps and front pipe

hks wastegate actuator

blitz air filters

cold air ducting

blitz bovs

fmic

apexi power fc

boost at 1.2 bar

tuned by con at C & V (aren't they supposed to be one of the best tuners around? so i guess shitty tuning isn't the answer... :) )

I have read this thread with great interest....

Nissaner,

190 4wkw at 1.2 bar seems a bit on the low side, BUT

Some Tuning shops Dynos show higher than true power figures to impress their customers. Maybe taking Ur car elsewhere would give u a Higher reading:D

C+ V 's dyno is probably accurate.

do you have an electronic boost controller?

have you had Ur injectors flowed?

cam timing gears settings ?

These are the only things i can think of

hope it gets the ball rolling.......

Akira:)

Hi nissaner, when you say "fmic", what brand? Have you tried the car with the standard GTR one? They flow OK to 300 rwkw, I have seen a lot of aftermarket ones that don't flow as well as a standard one.

Do you have a copy of your dyno run? Does it have the air fuel ratios shown on the graph? If not, get them to print it out (overlaying the horsepower graph) next time you are there. Post it and I'll have quick look for any obvious problems.

What fuel do you run and what was used when it was tuned?

Have you got a Commander for the PFC? What sort of detonation numbers do you get? Should be around 40 to 60 (not enough to set off the warning) which is a good sign that the tuning is close to the limit. If zero, it's tuned too conservatively.

If you want to check if your engine is OK, a leak down test will tell you. Any good performance shop should have a Snap On leak down tester.

Hope that helps.

i don't know what brand my intercooler is , as it just came with the car when i imported it from japan... so i don't have the standard one either... :P

i will try to scan the print out, i think it had four graphs (two in dark blue and two in lighter blue... lighter blue is what my car was running b4 the tuning, and darker is after the tuning)

i do have pfc commander , how do i check the detonation ? will check it tomorrow morning... :D

i used bp ulimate for that tuning session... i usually put mobil synergy8000 coz its just 10seconds drive from my house...

thanks for ur suggestions

Hi nissaner, on the Commander

select "Monitor"

then next button

then 8 channel

then next button

then check and make sure that "knock" has a number next to it. If it doesn't select it with the up and down and left and right buttons.

Then drive the car around and watch the "knock" readings, should be 40 to 6o for a 'tuned' GTR.

If you don't already have one, you should download the Commander Instruction Manual from the US Apexi site, it's in English. The one they have is not a Skyline one, but most of the stuff is the same.

You should really use the same fuel for tuning and normal driving if possible. My choices are BP Ultimate, then Optimax and then Mobil.

Hope that helps

hey nissaner you ever put your car down the qtr mile? if so what time you get? coz after reading your mods, i started to question my car as well.... all those mods i slapped on my car but i still pull a qtr mile time similar to a stock r32 gtr (a 12.8 - 9 in some mags).

i spent ~ $2000 to go .1 - .2 seconds faster?!?!? well thats what i base it on anyway...

mines a bit less mods than yours... only stuff i did was

power fc

3" trust jasma cat back (std dump/fron pipes still)

ebc set to 1bar

k&n pods

5 puck clutch, stronger press plate

z32 afms

EDIT: cam gears set to top end power (less torque)

210rwkw... on 2 other dynos the power reading was only about 2 - 3rwkw out so its pretty consistant.

i guess we've been spoilt by all the other gtr's doing faster times so naturally we think that we should also get around the same time with the same mods... :P

Yep I don't think 160-180 @ all 4 is stock. My GTR made 160kw@ all 4 with just a cat back exhaust. I don't see how 180 @ all 4's is even close!...... it depends on the dyno as well.

An HPI GTR made around 210 with cam gears, cat back, filters and 1.4 bar of boost so I don't know how some ppl get their figures....

Also dunno about flat 12's on stock turbos. To me it sounds like bullshit.... I am not saying its not possible but I'd like to see some timesheets to prove this. On lightly modified GTR's with stock turbos I've yet to see better than a mid to high 12's. On a very light tuned GTR I was only doing 13's

      The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter

      Single Turbo Conversion On R32 GTR.

      By Duncan · Posted

      Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
