Hey is that manual 6sp or auto? seems a little low actually, I was under the impression the V35s came stock with about 206-210kw (not at the wheels), so roughly ~158rwkw or ~211rwhp??

It's auto and actually it's too low. been serached all the stock dyno's on g35driver.com they have average 230-240hp

Its not a V35, but its close enough.

2003 VQ35DE in a Z33

JWT Popcharger

5/16" Intake Manifold Spacer

Motordyne MREV2

Reflashed factory ECU with higher redline

Unichip Piggyback

TopSpeed Extractors

Crawford Catalytic Converters

HiTech Exhaust

I've got several exhaust leaks at the moment, and the car's feeling a bit off, so I'm probably making less right now.

I've got my 2004 v35 dynoed at 153 kw at the rear wheels???

The only performance mod done is a cat back exhaust. Its no where near the 170 kw margin.

The dyno guy did have some trouble fixing the sensor into the single exhaust though. Should there be 2 sensors fixed if you've got a dual exhaust system??

Lets bring back this thread.

I dyno 177rwkw right now but picking up the V with new extractors tomorrow then i'll dyno again. (the extractors are really hard to put on)

When i got my car i put it on the dyno and got 163rwkw stock 03 auto.

Do you guys think there is about a 10kw diff in manuel and auto?

v35 paul,

i have since gone back to unigroup and redynoed my car.

i have serious doubts that their dyno was calibrated properly when the previous owner had done the 177kw run when it was stock.

I have since had the car dynoed twice since then.

First time, was after i installed the plenum spacer and CF Z-Tube car made 164rwkw. ISMR dyno.

The 2nd time, i installed the stillen Air intake, lightweight flywheel / clutch and teh Motordyne exhaust. Car made 174kw. Unigroup dyno.

I seriously doubt the mods i have done to this car have made it slower. I suspect the dyno may have been reading "happy" and have since been calibrated. the 174rwkw seems about right. The car does feel faster now than before, there is no doubt about it. So it definatley hasnt lost power.

Near when i first bought (exhaust, panel filter, tube, ground kit) - 131rwkw @ ISMR

Located and fixed overheating issue

Middle of ownership (exhaust, panel flter, tube, ground kit, HKS plugs, nismo thermostat, spacer) - 170rwkw @ ISMR

Just recently (ECU reflashed and rev limiter raised) - 182rwkw @ SAS

Car felt progressively/proportionately faster as i fixed the heat issue and added more mods. It's decent speed now, i'm very happy with it. I don't find myself thinking how i could make it faster anymore really.

Now it's more braking power i need.

Oh sorry, 03 6mt vq35de.

Edit - 182rwkw run also had gramlights on rear, a bit lighter than the factory 18"s. Even though they are wider and have larger tires on.

What did you reflash with?

Custom flash (for my engine and mods) at SAS.

A few people with Z/V have got it done at SAS.. but they are in Sydney unfortunately (if you were looking to chase that).

Car is giving 5.9s to 100 with a soft/medium launch, can't complain for n/a luxo cruiser :D

$1200.

It doesn't relearn, because they actually overwrite/write in their own data. I know one chip on the ECU actually gets replaced so unsure if AFR targets and ignition mapping is overwritten or even written onto the new chip they put in.

Proof that it doesn't relearn is the car hasn't pinged once since the flash/tune. Factory mapping had my engine pinging sometimes (quite a common problem on Z/V on forums).

If you do go ahead, just remember it's an n/a engine, don't expect massive amounts of difference before and after.

I did it more to get rid of the pinging myself. They managed to give me some noticeable mid range and top end gains however my low end suffered as ignition had to be pulled back considerably as the factory mapping was too aggressive causing the low end pinging.

    • Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga
    • yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching
    • Quite right, if you make it to that pension you deserve every cent
    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again馃様 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
