It looks either wastegate is unsealed or VCT is not activated.

Ask Sean to change the VCT settings through the ECU and see it response to power curve. 2ndly the actuator has to be removed for turbo installation and in many cases the pre-load was let by the operating mechanic (many believed they shouldn't be tensioned) or not been corrected adjusted after installation.

Drop the cat, have a play with the EBC, that dip and claiming back up shape looks strange. To get around the 280rwkws mark it needs to hold around 20psi up top.

Further more, pretty much all results came out of the test car are on aftermarket manifolds. I will see Trent next week to trail a larger turbine housing for the SS2, which should compensate a little working with stock exhaust manifold.

I installed turbo to engine, then engine into car. Actuator hasn't been adjusted. But i will check it Saturday morning And test Vct just to be sure.

Might be able to log boost against Rpm then drop Cat and compare and see if it gains much response

Thats honestly a pretty good graph man.. I can imagine you would want boost in as early as possible, and to hit the mark for power, but that is all in by 4k already.

It definitely has the marks of a fast car, and I do believe the turbo is performing based on the shape of the curve. For a turbo thats capable of more power, to me it looks like its not running enough boost, or theres a flow restriction of some sort (other than the turbo). As its only a minor hold back on boost and your missing 10-20% power.

Theres definitely more in it once you work out whats holding it back.

Hi all

I bought on of hypergears highflows around 6 months ago with the intention to put it on my track car, but as life likes to play its little games, the track car was stripped and sold.

But I kept a few select bits to make myself a budget, reliable and responsive daily driven drifter

A r33 4 door, so sticking to the budget I fitted a front mount cooler, a intank fuel pump, the highflow I had (r33 21U rear, 14psi actuator) and a microtech lt16 I had.

Then took it in for a tune, stock injectors(remember budget build) and all

So on a safe tune, to handle me thrashing it at the track :P

The injectors had a little left in them at 300hp but 282rwhp (208kw) was the final tune

For the very minimal cash outlay, I'm very very happy with the result

Interesting that they didn't use any correction method, I've never had a run on Allstar's dyno without SAE being used.

Make much difference?

I see mine says 2000+4000 while simonr32's says 2000+3000. Googled last night but didn't find an answer. I know nothing about correction methods so have some studying to do

Yeah I'm not too concerned. But would like to get the most out of it after spendibg so much time and money on it. Regardless I want to change exhaust from behind the dump, check all obvious things then wind more into it. I'm confident with more boost the power curve should be close to everyone else.

But yeah it feels fast as for me after only driving a ford ranger and grand vitara for the last 3 yrs ;)

Great result for a very budget build! That turbo would be good for 18psi at least, so I can see it would really come alive with some injectors and more boost.

Good work, I would be happy with the result of a nice reliable ultimately budget build like that.

Thanks mate, I did consider going the injector path but for the extra outlay I might just stick with this setup, it seems to drive so well and still has the balls to fry tyres rolling onto boost in lower gears.

Either way I am in QR matsuri in 2 weeks so will see how good it goes :)

a cheap option for injectors are S15 450cc injectors, they flow decent amount and can be had for next to nothing on silvia forums :woot:

just read you have a GT-t, fail on my side lol

Not a fail on your side, fail by me, I should update that, I've had 4 different cars since the r34 4 door

This is a series 1 r33 4 door :D

haha well there you go!

S15 450s will get you up to 230kw man, easily.

even more, I was making 246 kW on my old shitbox with the duty cycle at around 70ish %

I dont want to set the bar too high, it is a HF and is running a microguess. The microguess is the biggest holdup, to keep the tune safe I say discount about 20 from what it can do as a maximum.

Make much difference?

I wouldn't have a clue myself, but from memory Simon said it adds 7% to the total power. As does their dyno apparently. So together my power figure is apparently 14% out. I think that's what it worked out to, the question was whether my 393rwhp figure on Allstar's dyno was accurate compared to my 318rwhp on Autoworx Dyno Dynamics a day later.

haha well there you go!

Still a lot of effort for and extra 20 odd kw lol, but I will keep my eye out for some cheapies as I'm always on nissansilvia.com

But I have my basic engine setup I wanted :)

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
